Form 146 & Form 145 (Earlier Form 15CB & 15CA): Complete Guide to Non-Resident TDS, Section 393 (195) & DTAA Compliance

Executive Overview: Foreign remittance compliance and withholding tax deduction on payments to non-residents represent one of the highest-risk audit and litigation areas for Indian corporate finance teams and Chartered Accountants. With the transition from the Income-tax Act, 1961 to the Income-tax Act, 2025 (effective April 1, 2026) and the Income-tax Rules, 2026, the erstwhile Form 15CA and Form 15CB reporting regime under Section 195 has been restructured into Form 145 (remitter declaration) and Form 146 (Accountant's Certificate) alongside Section 393 (formerly Section 195). This comprehensive guide examines the statutory architecture, Double Taxation Avoidance Agreement (DTAA) vs domestic rate selection, grossing-up mechanics under Section 195A, SaaS and cloud payment characterisation controversies, electronic Form 10F and Tax Residency Certificate (TRC) verification, and a step-by-step compliance checklist for error-free filing.

• Statutory Transition: Understand how Section 195 and Rule 37BB map to Section 393 and the new Form 146 / Form 145 reporting structure from FY 2026–27 onwards.
• Chargeability Prerequisite: Why withholding triggers only on sums "chargeable under the provisions of the Act" (Supreme Court principle in GE India Technology Centre) as tempered by the explanation covering presence or business connection in India.
• Practical Execution Controls: How to resolve challan-linking delays, exchange-rate conversion rules (Rule 26 / SBI TT Buying Rate), net-of-tax grossing up, and penalty exposure under Section 271I (₹1,00,000 per default) while keeping working files organised in assureOffice.

1. Statutory Architecture: Why Foreign Remittance TDS Exists and How the 2026 Transition Works

When an Indian resident company, firm, or individual makes a payment to a domestic vendor, tax deduction at source (TDS) is governed by specific head-wise sections (such as contractor payments, professional fees, rent, or commission) with fixed monetary thresholds and low withholding rates (typically 1% to 10%). However, once the payee is a Non-Resident (not being a company) or a Foreign Company, the revenue collection risk fundamentally changes. Because the non-resident recipient typically lacks physical assets or a permanent tax presence within Indian jurisdiction, recovering unpaid income tax after the funds have been wired abroad via SWIFT is practically impossible for the tax administration.

To safeguard revenue at the point of outflow, Indian tax law establishes a two-pillar control mechanism at the remittance gateway:

1. Substantive Withholding Obligation: Under Section 195 of the Income-tax Act, 1961 (mapped to Section 393 of the Income-tax Act, 2025), any person responsible for paying to a non-resident or a foreign company any interest or any other sum chargeable under the provisions of the Act (other than income chargeable under the head "Salaries") must deduct income tax thereon at the time of credit of such income to the account of the payee or at the time of payment thereof in cash, by issue of a cheque or draft, or by any other mode, whichever is earlier, at the "rates in force".
2. Procedural Reporting & Certification Gatekeeper: Under Section 195(6) and the operational rules governing foreign remittances, the remitter must furnish an electronic declaration of the remittance, supported—where taxable payments exceed the prescribed annual threshold—by an independent verification certificate issued by a Chartered Accountant before the Authorised Dealer (AD Category-I Bank) processes the outward wire transfer.

Effective April 1, 2026, under the Income-tax Rules, 2026, the legacy forms have been renumbered and upgraded on the e-Filing portal to streamline data validation and challan reconciliation. CA firms managing multi-client compliance workflows through assurePractice and assureTax should align their internal checklists with the updated mapping below:

Compliance Parameter	Legacy Framework (Income-tax Act, 1961 & Rules, 1962)	Current Framework (Income-tax Act, 2025 & Rules, 2026)	Operational Impact for CA Firms & Corporates
Primary Withholding Section	Section 195 (Non-resident payments other than salary)	Section 393 (Consolidated non-resident withholding framework)	Core chargeability test ("sum chargeable to tax") and credit-vs-payment trigger remain unchanged; citations in legal opinions and tax audit working papers must reflect both references during transition years.
Remitter's Electronic Furnishing of Information	Form 15CA (Parts A, B, C, and D under Rule 37BB)	Form 145 (Parts A, B, C, and D)	Filed by the remitter on the Income Tax e-Filing portal; Part C explicitly requires assigning and linking the Chartered Accountant's certification before final submission.
Accountant's Certificate	Form 15CB	Form 146	Issued and digitally signed (DSC) by a Chartered Accountant for taxable remittances exceeding ₹5,00,000 in aggregate during the financial year where no Assessing Officer order (nil/lower withholding) covers the payment.
Quarterly Withholding Statement & Certificate	Form 27Q & Form 16A	Non-resident TDS Statement & Certificate workflows integrated with portal challan databases	Strict cross-validation between Form 145/146 remittance declarations and quarterly non-resident TDS statements; unlinked challans trigger automated compliance flags that surface during assureTax Clause 34 reviews.

2. Decoding the Structural Logic of Form 145 and Form 146 (With Practical Examples)

A frequent misconception among corporate accounts teams is that every single foreign payment requires a Chartered Accountant's certificate in Form 146. In reality, the reporting architecture segments outward remittances into four distinct buckets based on two variables: (a) whether the remittance is chargeable to tax in India, and (b) whether the aggregate taxable payments during the financial year exceed ₹5,00,000.

2.1 The Four-Part Classification Matrix of Form 145 (Earlier Form 15CA)

• Part A of Form 145 (Small Taxable Remittances up to ₹5,00,000): Applicable when the remittance—or the aggregate of such remittances made during the financial year—is chargeable to tax in India, and the total amount does not exceed ₹5,00,000. Here, the remitter self-declares the payment and TDS details directly in Part A without needing Form 146 from a Chartered Accountant or an order from the Assessing Officer.
  Practical Example: Zenith Manufacturing Pvt. Ltd. pays USD 3,500 (₹2,94,000) to a UK laboratory for one-time chemical testing where technical know-how is made available, and has no other taxable foreign remittances during the financial year. After deducting TDS at 10% under the India–UK DTAA, Zenith files Part A of Form 145 directly; Form 146 is not required. However, if Zenith makes a second taxable remittance of USD 4,000 (₹3,36,000) four months later, the cumulative annual taxable remittance reaches ₹6,30,000 (exceeding ₹5,00,000), triggering Form 146 + Part C of Form 145 for the second payment.
• Part B of Form 145 (AO Certificate Route): Applicable when the remittance is chargeable to tax and exceeds ₹5,00,000 in the financial year, and the remitter or non-resident payee has already obtained a specific certificate or order from the Assessing Officer (corresponding to erstwhile Section 195(2), Section 195(3), or Section 197) authorising nil or lower deduction of tax. Since the revenue department has already examined the transaction and fixed the withholding rate, an independent CA certificate in Form 146 is not required.
  Practical Example: An NRI sells a residential flat in Gurugram for ₹2.40 crore and obtains a lower withholding certificate from the International Taxation Ward authorising TDS at 4.16% (computed on actual long-term capital gains rather than 12.5% plus surcharge on the gross sale consideration). The resident buyer deducts tax per the certificate and files Part B of Form 145 citing the certificate number.
• Part C of Form 145 + Form 146 (CA Certification Route): Applicable when the remittance is chargeable to tax in India, exceeds ₹5,00,000 (individually or in aggregate during the financial year), and is not covered by an Assessing Officer certificate. The remitter must first assign Form 146 to their Chartered Accountant on the portal; once the CA verifies the agreements, invoices, TRC, Form 10F, and DTAA position and uploads Form 146 with a Digital Signature Certificate (DSC), the remitter reviews and e-verifies Part C of Form 145.
• Part D of Form 145 (Non-Taxable Remittances Outside the Exemption List): Applicable when the payment to the non-resident is not chargeable to tax under the Income-tax Act (or is exempt under the Act, rather than merely reduced to 0% by a tax treaty where domestic chargeability exists—a critical distinction discussed below), and does not fall within the specified list of 33+ exempt remittance purposes under the RBI current/capital account rules.
  Practical Example: An Indian exporter pays USD 12,000 (₹10,08,000) to an independent commission agent in Dubai who procures export orders entirely outside India, has no business connection or Significant Economic Presence in India, and renders no technical or managerial service under Section 9(1)(vii). Because the income does not accrue or arise in India even under domestic law, the payment is not chargeable to tax and can be reported under Part D of Form 145 (unless the AD bank specifically requests a CA certificate for trade verification).

2.2 Complete Exemption from Form 145 and Form 146 (The Specified Purpose List)

If an outward remittance falls within the statutory "Specified List" of nature/purpose codes prescribed under the rules (aligned with FEMA current and capital account classifications—such as Indian equity investment abroad under ODI, foreign business travel, medical treatment abroad, education fees, or pure freight/import payments covered by shipping bills/Bills of Entry) OR is made by an individual who is not required to obtain RBI prior approval under the Liberalised Remittance Scheme (LRS), neither Form 145 nor Form 146 is legally required under the Income-tax Rules.

3. The "Chargeability" Threshold: Domestic Law (Section 9) vs DTAA Benefit (Section 90)

Before calculating any withholding rate in Form 146, a Chartered Accountant must complete a structured two-step legal inquiry, because the certificate requires parallel reporting of taxability under the domestic Income-tax Act and under the applicable Double Taxation Avoidance Agreement (DTAA):

Step 1: Domestic Act Chargeability (Section 5(2) read with Section 9)

Under Section 5(2), a non-resident is taxable in India only on income that: (a) is received or deemed to be received in India, or (b) accrues or arises, or is deemed to accrue or arise, in India. Section 9(1) deems the following core categories of income to accrue or arise in India:

• Business Income via Business Connection or Significant Economic Presence (SEP): Income accruing directly or indirectly through or from any business connection in India, property in India, asset or source of income in India, or transfer of a capital asset situated in India. Explanation 2A to Section 9(1)(i) (and Rule 13 of the 2026 Rules) expands "business connection" to include Significant Economic Presence (SEP) where aggregate payments for goods/services/data downloads exceed ₹2 crore or systematic interaction exceeds 3,00,000 users in India.
• Interest (Section 9(1)(v)): Payable by the Government, or by a resident (unless the borrowed funds are utilised for a business or profession carried on outside India or for making/earning income from any source outside India), or by a non-resident where the debt is used for a business carried on in India.
• Royalty (Section 9(1)(vi)): Consideration for the transfer of all or any rights (including the granting of a licence) in respect of a patent, invention, model, design, secret formula, process, trademark, or copyright; or for the use of industrial, commercial, or scientific equipment. Importantly, domestic Explanations 4, 5, and 6 give an expansive definition covering computer software, regardless of medium, and satellite/transponder transmission.
• Fees for Technical Services — FTS (Section 9(1)(vii)): Any consideration (including lump-sum consideration) for the rendering of any managerial, technical, or consultancy services (including the provision of services of technical or other personnel), excluding consideration for any construction, assembly, mining, or like project undertaken by the recipient or income chargeable under "Salaries". Under the Explanation to Section 9(2), neither a place of business in India nor physical rendering of services inside India is required for Royalty or FTS to be deemed to accrue in India—it is sufficient that the services are utilised in a business or profession carried on in India.

Step 2: Treaty Override and Beneficial Provisions (Section 90(2))

Once domestic taxability is established, the practitioner evaluates the applicable DTAA between India and the payee's country of residence. Under Section 90(2), the provisions of the domestic Act apply only to the extent they are more beneficial to the taxpayer than the DTAA. Treaty provisions frequently offer three crucial reliefs that substantially narrow or eliminate the domestic tax charge:

1. Permanent Establishment (PE) Protection for Business Profits (Article 7): Even if a non-resident exceeds India's domestic Significant Economic Presence (SEP) threshold or has a loose "business connection" under Section 9(1)(i), if the transaction constitutes Business Profits and the non-resident does not have a Fixed Place PE, Service PE, Installation PE, or Dependent Agent PE in India under Article 5 of the relevant DTAA, the business profits are not taxable in India at all.
2. Copyright vs Copyrighted Article Distinction in Software Payments (Article 12): Following the landmark Supreme Court ruling in Engineering Analysis Centre of Excellence Pvt. Ltd. v. CIT (2021), while India's domestic Explanation 4 to Section 9(1)(vi) treats end-user software licences as Royalty, most Indian DTAAs patterned on the OECD Model define Royalty narrowly as payment for the use of, or the right to use, a copyright. Where a resident buys off-the-shelf software, SaaS subscriptions, or shrink-wrapped licences without acquiring the right to reproduce or commercially exploit the underlying source code/copyright, the payment is protected under the DTAA from Royalty characterisation and falls under Article 7 (Business Profits).
3. The "Make Available" Clause in Fees for Technical Services (Article 12 / 13): DTAAs with major jurisdictions including the USA, UK, Singapore, Netherlands, Canada, and Australia contain a restrictive "Make Available" condition for FTS (or Fees for Included Services). Under this test, routine consultancy, testing, management review, or support services do not qualify as taxable FTS under the treaty unless the service provider transfers technical knowledge, experience, skill, know-how, or processes in a manner that enables the Indian recipient to apply the technology independently in the future without recourse to the provider.

4. Practical Challenges, Case Studies & Numerical Illustrations

While the statutory text appears straightforward, CA firms certifying Form 146 and corporate tax teams handling foreign vendor payments face recurring operational roadblocks. Below is a detailed analysis of the eight most contested practical problems, along with worked-out examples and legally defensible resolutions.

Challenge 1: Should a Remittance Tax-Exempt Only Because of a DTAA Be Reported in Part D or Part C (Form 146)?

The Practitioner Dilemma: Suppose an Indian company, Apex Pharma Ltd., pays USD 25,000 (₹21,00,000) to a US consulting firm for regulatory market research in North America. Under domestic Section 9(1)(vii), consultancy is taxable as FTS at 20% (plus surcharge and cess). However, under Article 12(4)(b) of the India–USA DTAA, because no technical knowledge or proprietary process is "made available" to Apex Pharma and the US firm has no PE in India, the tax rate is Nil (0%). Can Apex Pharma simply file Part D of Form 145 ("not chargeable to tax") without obtaining a CA's certificate in Form 146?

The Technical Resolution: Relying on Part D when domestic chargeability exists under Section 9(1)(vii) and non-taxability arises solely from interpreting a DTAA clause (such as "Make Available" or absence of PE) is risky and routinely rejected by AD Category-I banks. Moreover, determining whether a service satisfies the "Make Available" test or whether TRC/Form 10F is valid requires professional examination. Therefore, best practice—and the standard requirement of Indian AD banks—is to route treaty-exempt service remittances exceeding ₹5,00,000 through Form 146 (CA Certificate) + Part C of Form 145, where the CA records the 20.80% domestic tax liability under the Domestic Act section of the form and explicitly certifies 0% DTAA eligibility under the DTAA section on the strength of a valid TRC, electronic Form 10F, and No-PE declaration.

Challenge 2: Electronic Form 10F Filing When the Non-Resident Vendor Does Not Have an Indian PAN

The Practitioner Dilemma: Under Section 90(4) and 90(5), claiming ANY benefit under a DTAA requires two mandatory documents from the non-resident payee: (1) a Tax Residency Certificate (TRC) issued by the foreign government/revenue authority covering the relevant period, and (2) Form 10F whenever prescribed particulars (such as status, nationality/incorporation, tax identification number, period of residential status, and address) are not all explicitly printed on the face of the TRC (which is true for almost all US Form 6166, UK, and Singapore TRCs). How does a foreign vendor without an Indian PAN file electronic Form 10F on the Indian Income Tax portal?

The Technical Resolution: The Income Tax e-Filing portal provides a dedicated registration category: "Non-Residents not holding and not required to have a PAN". The foreign vendor can register using their foreign Tax Identification Number (TIN), email, and mobile OTP, attach their TRC PDF, and e-verify Form 10F online using an electronic verification code. Crucial Warning for CAs: Do not sign Form 146 granting a lower DTAA rate or 0% treaty exemption merely on a manually signed Word/PDF copy of Form 10F; during Section 201(1) / 201(1A) withholding audits, Assessing Officers routinely disallow treaty rates and demand domestic rates (plus 1% / 1.5% monthly interest) if the portal-generated e-Form 10F acknowledgement number is missing on the date of certification. When tracking such vendor documents across clients, firms can log document status and follow-up tasks inside assurePractice so no remittance gets delayed at the bank desk.

Challenge 3: Grossing Up Under Section 195A When the Foreign Vendor Demands "Net of Tax" Payment

The Practitioner Dilemma: Foreign SaaS providers, cloud platforms, international law firms, and specialized equipment suppliers routinely include a standard contractual clause: "All invoice amounts are net of any Indian withholding taxes; if withholding is required by law, the Customer shall gross up the payment so that Vendor receives 100% of the invoice value." How does grossing up interact with DTAA rates vs domestic rates, and what happens if the non-resident lacks a PAN (Section 206AA)?

The Technical Resolution: Under Section 195A, where under an agreement or other arrangement the tax chargeable on any income is to be borne by the person by whom the income is payable (the Indian remitter), then for the purposes of deduction of tax, such income must be increased to such amount as would, after deduction of tax thereon at the rates in force for the financial year, be equal to the net amount payable under such agreement.

Detailed Numerical Illustration of Grossing Up (Domestic vs DTAA Rate):

• Scenario: An Indian company, Orion Tech Pvt. Ltd., must remit USD 10,000 (equivalent to ₹8,40,000 at the SBI TT Buying Rate of ₹84.00/USD) as taxable Royalty/FTS to a foreign vendor, and Orion Tech bears the tax cost under the contract.
• Case A — Foreign Vendor Provides Valid TRC & e-Form 10F (DTAA Rate = 10% flat, inclusive of surcharge and cess):
  Remember that DTAA rates are holistic maximum caps—surcharge and health & education cess (4%) are not added on top of a DTAA rate of 10% or 15%.
  Grossed-up Taxable Income = ₹8,40,000 ÷ (1 - 0.10) = ₹8,40,000 ÷ 0.90 = ₹9,33,333.
  TDS Payable at 10% on ₹9,33,333 = ₹93,333.
  Net Remittance to Foreign Vendor = ₹8,40,000 (USD 10,000).
  Total Cash Outflow for Orion Tech = ₹8,40,000 + ₹93,333 = ₹9,33,333.
• Case B — Foreign Vendor Refuses to Provide TRC / Form 10F (Domestic Act Rate for Royalty/FTS = 20% + Surcharge + 4% Cess):
  Assuming total payments to that foreign company are below ₹1 crore (0% surcharge for foreign company; note that 2% surcharge applies between ₹1 crore and ₹10 crore, and 5% above ₹10 crore), the effective domestic rate is 20% × 1.04 = 20.80%.
  Grossed-up Taxable Income = ₹8,40,000 ÷ (1 - 0.208) = ₹8,40,000 ÷ 0.792 = ₹10,60,606.
  TDS Payable at 20.80% on ₹10,60,606 = ₹2,20,606 (more than 2.36 times the tax cost of Case A!).
  Total Cash Outflow for Orion Tech = ₹8,40,000 + ₹2,20,606 = ₹10,60,606.
• The Section 206AA (No-PAN) Rule 37BC Relief: What if the foreign vendor has no Indian PAN? Section 206AA mandates withholding at the higher of the rate in force or 20%. However, two vital protections apply: (1) per settled High Court precedents (including Danisco India Pvt. Ltd. and Nagarjuna Fertilizers), Section 206AA cannot override the beneficial DTAA rate under Section 90(2) if the non-resident qualifies for treaty protection; and (2) under Rule 37BC, Section 206AA does not apply to payments in the nature of interest, royalty, fees for technical services, dividend, or capital asset transfers if the non-resident furnishes their name, email, contact number, foreign address, TRC, and foreign Tax Identification Number (TIN).

Challenge 4: Timing of Exchange Rate Conversion (Rule 26 vs Rule 115) and Accounting Credit vs Remittance Date

The Practitioner Dilemma: Suppose an Indian company receives an invoice of USD 50,000 from a German technical engineering consultant on February 10, 2026, books the expense in Tally on February 15, 2026 (when the SBI TT Buying Rate is ₹83.50/USD), and actually makes the bank remittance and obtains Form 146 on March 20, 2026 (when the SBI TT Buying Rate is ₹84.20/USD and the bank's actual TT Selling Rate debited to the bank account is ₹84.65/USD). Which date triggers the TDS obligation, which exchange rate must be used in Form 146, and how should the accounting entries be passed?

The Technical Resolution:

1. Point of Tax Deduction: Under Section 195(1) / Section 393, TDS must be deducted at the earlier of credit of income to the payee's account (including a "Suspense Account" or "Provision for Expenses Account") or actual payment. Thus, because the invoice was credited in the books on February 15, TDS became deductible on February 15 and had to be deposited to the government by March 7.
2. Prescribed Exchange Rate (Rule 26): For the purpose of deduction of tax at source on any income payable in foreign currency, Rule 26 mandates using the Telegraphic Transfer (TT) Buying Rate adopted by the State Bank of India (SBI) on the date on which tax is required to be deducted (i.e., February 15 at ₹83.50/USD, NOT the RBI Reference Rate or the bank's actual TT Selling Rate on March 20).
   Worked Calculation: On February 15, taxable base = USD 50,000 × ₹83.50 = ₹41,75,000. Under the India–Germany DTAA (10% rate on FTS), TDS deductible on February 15 = 10% of ₹41,75,000 = ₹4,17,500 (equivalent to USD 5,000). When remitting the net USD 45,000 on March 20 at the bank selling rate of ₹84.65, the actual bank debit is ₹38,09,250, and the difference of ₹51,750 (₹38,09,250 - ₹37,57,500) is accounted for as a Foreign Exchange Fluctuation Loss in the Profit and Loss Account (which can be reviewed and grouped cleanly in assureFinancials). No additional TDS is required purely on account of currency depreciation between the date of credit and the date of remittance.
3. Avoiding the Form 146 Challan Trap: One of the most common errors in foreign remittance compliance is generating and signing Form 146 before the TDS challan is paid, or forgetting to enter the BSR Code, Challan Serial Number, and Deposit Date in the form. Ensure that the TDS is calculated using the SBI TT Buying Rate on the date of credit/payment, deposited via the e-Pay Tax portal, and the exact challan particulars are populated before finalising Form 146 and Part C of Form 145.

Challenge 5: SaaS, Cloud Hosting (AWS/Azure/Google Cloud), and Digital Advertising (Meta/Google Ireland) Payments

The Practitioner Dilemma: Almost every modern company pays foreign entities for cloud servers, SaaS subscriptions (CRM, ERP, design tools), or online marketing. Tax auditors and certifying CAs face constant pressure: clients argue that following Engineering Analysis (SC) and High Court rulings (such as Amazon Web Services and Salesforce), standard cloud/SaaS subscriptions do not involve transfer of copyright or physical control over equipment and are therefore not Royalty/FTS, whereas Assessing Officers during surveys treat all software/cloud outflows as taxable Royalty under Explanation 4/5 to Section 9(1)(vi). How should a CA approach Form 146 for these payments?

The Technical Resolution:

• Examine the Exact Contract & Billing Entity: First, verify whether the billing entity is actually a non-resident (e.g., Amazon Web Services Inc. in the US or Google Ireland Ltd.) or an Indian reseller/subsidiary (e.g., Google India Pvt. Ltd. or Microsoft Corporation India Pvt. Ltd.). If the invoice carries an Indian PAN and GSTIN, it is a domestic resident payment governed by domestic TDS sections (194J / 194C / 194Q), not Section 195 / Form 146.
• Apply the Dual Filter (Domestic vs DTAA): Under domestic law (Explanations 4 and 5 to Section 9(1)(vi)), the tax department's statutory text still treats software and server access broadly as Royalty. Therefore, taking a "Nil tax" position under the Domestic Act alone (without treaty protection) carries high litigation exposure. To certify 0% withholding on standard SaaS or cloud hosting in Form 146, the CA must rely on the applicable DTAA (supported by a valid current-year TRC, e-Form 10F, and No-PE declaration from the vendor) and verify that: (a) the user agreement grants only non-exclusive access to a standard cloud service without copyright reproduction or source-code modification rights, (b) the customer has no physical possession or exclusive operational control over the servers (ruling out Industrial/Commercial Equipment Royalty under the treaty), and (c) there is no human technical intervention that "makes available" technical know-how.

Challenge 6: Reimbursement of Expenses to Foreign Parent / Associated Enterprise (AE)

The Practitioner Dilemma: An Indian subsidiary reimburses its foreign parent company in Singapore USD 80,000 for global ERP licences, expatriate travel expenses, and regional IT support costs allocated on a "cost-to-cost without mark-up" basis. Does pure reimbursement require TDS deduction and Form 146 certification?

The Technical Resolution: Labelling an invoice as "Reimbursement of Expenses at Actuals" does not automatically grant immunity from withholding tax. Courts and Tribunals distinguish between two fundamentally different situations:

1. Pure Third-Party Pass-Through (Conduit Reimbursement): Where the foreign parent merely paid an airline, hotel, or independent software vendor as a disbursing agent for administrative convenience, supported by back-to-back third-party invoices showing that the underlying payment itself is not taxable in India, there is no income element embedded in the reimbursement.
2. Cost-Sharing / Intra-Group Service Allocation: Where a foreign parent allocates a share of centralized management, IT, HR, or R&D costs (even without a profit mark-up), Indian courts (including the Supreme Court in Centrica India Offshore on secondment of employees and ITAT benches on management cost allocations) hold that the gross receipt itself must be tested for FTS/Royalty or Service PE characterisation; absence of profit mark-up does not negate taxability on a gross basis under Section 195 / Article 12. Always inspect the underlying third-party invoices, cost-allocation keys, and Transfer Pricing study in assureTP before certifying nil tax on intra-group reimbursements.

Challenge 7: Import of Capital Machinery with Incidental Installation, Commissioning, or Training Services

The Practitioner Dilemma: A Gujarat-based auto-component manufacturer imports a CNC robotic line from Japan under a composite purchase order for EUR 500,000, comprising EUR 450,000 for CIF supply of machinery and EUR 50,000 for 15 days of on-site supervision, commissioning, and operator training in India. How should the remittance be handled?

The Technical Resolution: Pure offshore supply of machinery (EUR 450,000) where title and risk pass outside India (and payment is made through the AD bank against the Bill of Entry and shipping documents) is not chargeable to tax in India and falls under the exempt trade remittance category. However, the EUR 50,000 component for on-site installation, commissioning, and training is a service rendered and utilised in India, taxable domestically under Section 9(1)(vii). Under the India–Japan DTAA (which taxes FTS at 10% without a restrictive "Make Available" clause), or under treaties like India–USA/UK/Singapore where operator training "makes available" technical skill to the buyer's engineers, the EUR 50,000 service portion attracts 10% withholding tax and requires Form 146 + Part C of Form 145. Never club a taxable installation or training service invoice under an "Import of Capital Goods" purpose code to bypass Form 146.

Challenge 8: Interaction Between Non-Resident TDS Defaults, Tax Audit (Form 3CD Clause 34 & Clause 21(b)), and Section 40(a)(i) Disallowance

The Practitioner Dilemma: What happens during the year-end Tax Audit if a company deducted TDS on a non-resident payment late, or failed to deduct TDS on a March 31 year-end audit provision for foreign consultancy expenses?

The Technical Resolution: Unlike domestic payments under Section 40(a)(ia) where non-deduction or late payment of TDS leads to a 30% disallowance of the expenditure, under Section 40(a)(i) (applicable to payments to non-residents or outside India), failure to deduct TDS or failure to deposit the deducted tax on or before the due date of filing the income tax return under Section 139(1) results in a 100% disallowance of the entire expenditure in computing business income! Furthermore, in the Tax Audit Report (Form 3CD), the tax auditor must report all such defaults under Clause 21(b)(i) (disallowance u/s 40(a)(i)) and reconcile them with Clause 34(a), 34(b), and 34(c) (TDS deduction, Form 27Q filing dates, and interest u/s 201(1A)). Using assureTax within the assureOffice Practice Suite ensures that any non-resident TDS default in Clause 34 automatically flows into the Disallowance Report for Clause 21(b)(i) and ITR computation review in assureITR.

5. Step-by-Step Verification Checklist for Chartered Accountants Before Signing Form 146

Before affixing a Digital Signature Certificate (DSC) to Form 146 and generating the Unique Document Identification Number (UDIN) on the ICAI portal, the certifying Chartered Accountant should maintain a structured working paper file containing the following ten checkpoints:

Step	Verification Checkpoint	Primary Evidence / Source Document Required	Common Pitfall to Avoid
01	Confirm Payee Residential Status & Legal Entity	Master Service Agreement (MSA), Purchase Order, Certificate of Incorporation / Passport	Assuming a foreign brand name means non-resident payee without checking if the invoice is raised by an Indian branch or subsidiary.
02	Verify Remittance Purpose Code & RBI FEMA Permissibility	AD Bank Remittance Request (Form A2), FEMA Current/Capital Account Schedule	Selecting an incorrect RBI purpose code (e.g., S1007 vs S1023) that conflicts with the tax characterisation in Form 146.

6. Streamlining Non-Resident Withholding, Clause 34 & Disallowance Reviews in assureOffice

In a busy CA practice or corporate finance department, foreign remittance compliance does not end when the wire transfer leaves the bank. Every Form 146 and Form 145 filed during the year creates downstream reporting obligations across quarterly non-resident TDS returns, financial statement foreign exchange notes, Tax Audit Form 3CD, and Transfer Pricing Form 3CEB.

Within the assureOffice ecosystem and Practice Suite, teams can connect these checkpoints without repetitive manual entry:

• Tax Audit Clause 21(b), Clause 23 & Clause 34 in assureTax: When preparing Form 3CA/3CB–3CD in assureTax, imported Tally ledgers, TDS statements, and challan records help identify foreign vendor payments, verify whether tax was deducted and deposited before the Section 139(1) due date, and populate Clause 34(a)–(c) alongside the automated Disallowance Report for Section 40(a)(i) review.
• Associated Enterprise Cross-Checks in assureTP: Where foreign remittances involve royalty, technical services, management charges, or cost reimbursements to an Associated Enterprise, assureTP lets the team reuse AE master details, reconcile transaction values with books and Form 146 certificates, and prepare Form 3CEB disclosures in a shared browser workspace.
• Schedule III Foreign Currency Disclosures & Proceeding Tracking: Use assureFinancials to maintain clean ledger groupings for foreign exchange fluctuations and assureNotice to track any Section 201(1) / 195 withholding verification notices and compliance deadlines in one central dashboard.
• Recurring Compliance Assignment Tracking in assurePractice: Convert recurring foreign remittance certifications, quarterly non-resident TDS filings, and annual Form 3CEB engagements into structured team assignments and billing workflows using assurePractice.

7. Frequently Asked Questions (Practitioner FAQ Bank)

1. What is the difference between Form 145 / Form 146 and the earlier Form 15CA / Form 15CB?
   Under the Income-tax Act, 2025 and Income-tax Rules, 2026 (effective April 1, 2026), Form 145 replaces Form 15CA (remitter's declaration of foreign remittance) and Form 146 replaces Form 15CB (Accountant's certificate). They serve the same substantive compliance function for non-resident payments under Section 393 (formerly Section 195), with enhanced portal validation.
2. When is Form 146 (Accountant's Certificate) mandatory?
   Form 146 is required whenever a payment or aggregate of payments made during a financial year to a non-resident (or foreign company) is chargeable to tax in India, exceeds ₹5,00,000, and is not covered by a nil or lower withholding certificate/order from the Assessing Officer.
3. Is surcharge and 4% Health & Education Cess added to a DTAA withholding rate?
   No. When tax is deducted at the beneficial rate specified in a Double Taxation Avoidance Agreement (DTAA)—such as 10% or 15% on Royalty, FTS, or Interest—that treaty rate is an all-inclusive cap. Surcharge and 4% cess are added only when computing tax under the domestic Income-tax Act rates.
4. What is the penalty for failing to furnish Form 145 / Form 146 or furnishing inaccurate information?
   Under Section 271I of the Income-tax Act, 1961 (and its corresponding penalty provision under the 2025 Act), if a person who is required to furnish information regarding a foreign remittance fails to furnish such information or furnishes inaccurate information, the Assessing Officer may direct payment of a penalty of ₹1,00,000 per default.
5. Can an Indian company claim DTAA benefit for a foreign vendor solely on the basis of an invoice address?
   No. Section 90(4) strictly mandates obtaining a valid Tax Residency Certificate (TRC) issued by the government of the foreign country or specified territory, supplemented by electronic Form 10F under Section 90(5) where required particulars are not present in the TRC.
6. If a foreign vendor does not have an Indian PAN, is 20% TDS mandatory under Section 206AA?
   No, provided the payee qualifies under Rule 37BC (for payments in the nature of interest, royalty, FTS, dividend, or capital gains) by furnishing their name, email ID, contact number, address in the country of residence, TRC, and foreign Tax Identification Number (TIN). Furthermore, courts have consistently held that Section 206AA cannot override a lower beneficial rate under an applicable DTAA.
7. Which exchange rate must be used while computing TDS in Form 146?
   Per Rule 26 of the Income-tax Rules, the remitter and certifying CA must use the State Bank of India (SBI) Telegraphic Transfer (TT) Buying Rate prevailing on the date on which tax is required to be deducted (i.e., the earlier of accounting credit or actual payment).
8. Does import of physical goods require Form 145 or Form 146?
   Pure offshore supply/import of physical goods where title passes outside India is not chargeable to tax in India and is included in the exempt purpose list, so neither Form 145 nor Form 146 is statutorily required. However, any separate or embedded taxable service (such as installation, commissioning, or technical training in India) requires withholding review and reporting.
9. What happens if a remitter discovers an error in Form 145 or Form 146 after submission?
   Both Form 145 and Form 146 can be withdrawn online on the e-Filing portal within the permitted withdrawal window (typically within 7 days of submission, provided the form has not yet been acted upon or locked by the AD bank workflow), after which a fresh corrected certificate and declaration can be filed.
10. How does non-deduction of TDS on a foreign payment affect the payer's income tax computation?
    Under Section 40(a)(i), 100% of the expenditure payable to a non-resident is disallowed while computing business income if tax is not deducted or, after deduction, is not paid on or before the due date of filing the return under Section 139(1). The expense is allowed only in the subsequent year in which the TDS is actually paid.
11. Is TDS applicable on payments made through a corporate credit card to foreign software platforms (like Zoom, Canva, or Adobe)?
    The mode of payment (corporate credit card vs wire transfer) does not alter substantive chargeability under Section 195 / Section 393. While credit card gateways often bypass the manual AD bank Form 145/146 pre-check at the moment of swipe, the tax auditor must still evaluate the aggregate foreign software expenses during the Tax Audit under Clause 21(b) and Clause 34 in assureTax for domestic vs DTAA Royalty/FTS taxability.
12. What is the difference between the "Make Available" clause in the India–USA/UK/Singapore DTAA and the India–Germany/France DTAA?
    The India–USA, UK, and Singapore DTAAs restrict FTS/FIS taxation to services that "make available" technical knowledge, skill, or processes enabling the recipient to perform the function independently. By contrast, treaties like India–Germany do not contain a narrow "make available" clause in their FTS article, making routine technical and consultancy services taxable at the treaty rate (typically 10%) even without technology transfer.
13. Does India's Most Favoured Nation (MFN) clause automatically reduce the DTAA rate from 10% to 5%?
    Following the Supreme Court's landmark judgment in AO (International Taxation) v. Nestle SA (2023), an MFN clause in a DTAA cannot be invoked automatically unless the Government of India has issued a specific, separate notification under Section 90 notifying the incorporation of that lower third-country treaty rate. Certifying CAs must never apply an unnotified MFN rate in Form 146.
14. Does payment to an Indian branch of a foreign bank or foreign shipping line require Form 146?
    Any payment made to a non-resident remains subject to non-resident withholding unless covered by a lower/nil deduction certificate issued by the Assessing Officer (such as a Section 195(3) / 197 certificate commonly obtained by Indian branches of foreign banks) or specific statutory shipping assessment provisions under Section 172 (as clarified by CBDT Circular No. 723).
15. How long must the remitter and Chartered Accountant preserve supporting documents for Form 146?
    Because non-resident withholding proceedings under Section 201 and reassessment notices can examine cross-border transactions across extended limitation windows, firms should retain the signed contracts, invoices, TRC, e-Form 10F, No-PE declarations, SBI TT Buying Rate proof, and challan receipts in their assureOffice client workspace for at least 8 to 10 assessment years.
