Executive Overview
The introduction of Rule 86B into the Central Goods and Services Tax (CGST) Rules, 2017 represents one of the most targeted anti-evasion safeguards implemented in the Goods and Services Tax architecture. Notified by the Central Board of Indirect Taxes and Customs (CBIC) via Notification No. 94/2020-Central Tax (effective 1st January 2021), Rule 86B restricts the utilization of balances lying in the Electronic Credit Ledger (Input Tax Credit / ITC) to discharge output tax liabilities. Specifically, it mandates that registered persons having monthly taxable supplies exceeding fifty lakh rupees (₹50,00,000) cannot utilize ITC to discharge more than ninety-nine per cent (99%) of their total output tax liability, compelling them to discharge at least one per cent (1%) of their output tax liability in hard currency through the Electronic Cash Ledger.
The legislative intent behind Rule 86B was to curb the proliferation of fraudulent "fly-by-night" shell companies and bogus circular invoicing networks that artificially generated colossal amounts of fake input tax credit to wipe out 100% of their output tax liabilities without contributing a single rupee to the Government treasury. However, because Rule 86B operates on quantitative turnover benchmarks, it frequently ensnares legitimate, high-volume capital-intensive manufacturing enterprises, high-turnover low-margin traders, and rapidly expanding businesses that hold genuine, accumulated input tax credit. For tax controllers, chief financial officers, and tax practitioners, navigating Rule 86B requires continuous monitoring of monthly taxable turnovers, tracking statutory exemptions under its provisos, and reconciling monthly GSTR-3B filings to prevent cash-flow shocks.
In parallel, tax authorities frequently invoke Rule 86A, which empowers senior officers to block the Electronic Credit Ledger entirely upon recording "reasons to believe" that credit was availed fraudulently. Managing these overlapping restrictions requires automated compliance management platforms. Within the assureOffice suite, assureTax continuously monitors monthly taxable turnovers, evaluates Rule 86B exemption eligibility across income tax filings and export refunds, and automates 1% cash ledger challan generation, while assureNotice tracks Rule 86A blocking orders and manages legal representations. This guide delivers a definitive, practitioner-grade exploration of Rule 86B and Rule 86A, dissecting statutory exemptions, computational mechanics, circular instructions, and High Court writ jurisprudence.
Comparative Framework: Rule 86A (Credit Blocking) vs Rule 86B (Credit Utilization Capping)
Tax professionals must clearly distinguish between Rule 86A, which constitutes a complete freeze on specific credit ledgers, and Rule 86B, which establishes an overarching 99% utilization cap on monthly output tax liabilities. The table below delineates the statutory differences between both provisions under the CGST Rules, 2017.
| Statutory Dimension | Rule 86A (Blocking of ITC in Credit Ledger) | Rule 86B (Restrictions on ITC Utilization) |
|---|---|---|
| Statutory Objective | Prevent fraudulent credit syndicates from passing on or utilizing bogus ITC. | Ensure high-turnover entities contribute at least 1% output tax in cash. |
| Enacting Notification | Notification No. 75/2019-Central Tax (effective 26th December 2019). | Notification No. 94/2020-Central Tax (effective 1st January 2021). |
| Authorizing Authority | Commissioner or officer authorized by him not below rank of Assistant Commissioner. | Automatic rule of law enforced by the GST Common Portal algorithm. |
| Prerequisite Threshold | "Reasons to believe" in writing that ITC was availed fraudulently or without goods. | Monthly taxable turnover (excluding exempt/zero-rated) exceeding ₹50,00,000. |
| Operational Impact | Debit to the Electronic Credit Ledger is completely blocked up to the specified amount. | ITC utilization capped at 99% of output tax; 1% must be paid via Cash Ledger. |
| Target Amount | Specific fraudulent invoice amounts identified during investigation. | Applicable on total monthly output tax liability appearing in Table 6.1 of GSTR-3B. |
| Statutory Sunset / Tenure | Automatically ceases to have effect upon expiry of one (1) year from blocking. | Applies indefinitely on every monthly return where turnover exceeds ₹50 Lakh. |
| Statutory Provisos / Exceptions | Unblocked if officer is satisfied that conditions for blocking no longer exist. | Five explicit statutory safe-harbor exemptions under the proviso to Rule 86B. |
| Judicial Relief Mechanism | Writ petition under Article 226 for lack of "reasons to believe" or procedural breach. | Administrative verification of exemptions; writ petition if portal forces illegal cash tax. |
Detailed Statutory Architecture & Procedural Mechanics
1. The Primary Mandate of Rule 86B
Rule 86B of the CGST Rules, 2017 establishes an overriding restriction on the Electronic Credit Ledger:
"Notwithstanding anything contained in these rules, the registered person shall not use the amount available in electronic credit ledger to discharge his liability towards output tax in excess of ninety-nine per cent of such tax liability, in cases where the value of taxable supply other than exempt supply and zero-rated supply, in a month exceeds fifty lakh rupees:"
The rule applies strictly to monthly returns filed in Form GSTR-3B. If an enterprise has an aggregate output tax liability of ₹20,00,000 in a month where its taxable supply exceeds ₹50 Lakh, it can utilize its Electronic Credit Ledger to offset up to a maximum of ₹19,80,000 (99% of ₹20,00,000). The remaining ₹20,000 (1%) must be discharged through the Electronic Cash Ledger via an electronic cash challan (CPIN), even if the company holds an unutilized input tax credit balance of ₹5 Crore.
2. Deconstructing the ₹50 Lakh Monthly Turnover Benchmark
The ₹50 Lakh threshold is evaluated on a month-to-month basis for each GSTIN individually. The statutory formula for computing the threshold requires careful segregation:
- Included in Threshold: All intra-state supplies (CGST + SGST), inter-state supplies (IGST), and deemed exports subject to GST.
- Strictly Excluded from Threshold:
- Exempt Supplies: Supplies of goods or services attracting a nil rate of tax, wholly exempt supplies under Section 11, and non-taxable supplies under Section 9(2) (petroleum crude, high-speed diesel, motor spirit, natural gas, aviation turbine fuel, and alcoholic liquor for human consumption).
- Zero-Rated Supplies: Physical exports of goods or services, and supplies made to Special Economic Zone (SEZ) developer or SEZ units (whether made with payment of tax or under Letter of Undertaking / LUT).
If an enterprise generates ₹45,00,000 of domestic taxable supplies, ₹80,00,000 of zero-rated exports under LUT, and ₹30,00,000 of exempt agricultural supplies in a month, its qualifying taxable supply is strictly ₹45,00,000. Because ₹45 Lakh does not exceed the ₹50 Lakh threshold, Rule 86B is completely inapplicable for that month, allowing the entity to utilize 100% ITC to discharge its domestic liability.
3. Statutory Safe-Harbor Exceptions under the Proviso to Rule 86B
To prevent genuine taxpayers from facing undue working capital blockages, Parliament enacted five specific statutory exceptions under the proviso to Rule 86B. If a taxpayer satisfies any ONE of these five conditions, the 99% cap is completely waived, restoring the right to utilize 100% ITC:
Exception 1: Income Tax Payment Exceeding ₹1 Lakh (Proviso Clause a)
Rule 86B shall not apply if the registered person or the proprietor, or karta, or the managing director, or any of its two partners, whole-time directors, members of Managing Committee of Associations or Board of Trustees, as the case may be, have paid more than one lakh rupees (₹1,00,000) as income tax under the Income-tax Act, 1961 in each of the last two financial years for which the time limit to file return of income under Section 139(1) has expired.
Key Compliance Nuance: The income tax payment refers to actual tax liability discharged (after deducting TDS/TCS or via advance tax/self-assessment tax). For corporate entities, if the company itself paid more than ₹1 Lakh income tax in each of the preceding two financial years, the exemption is satisfied. For private companies or LLPs where the entity had tax holidays or losses, the exemption can be established if any two directors or partners paid > ₹1 Lakh income tax individually.
Exception 2: Refund of Unutilized ITC Exceeding ₹1 Lakh (Proviso Clause b)
Rule 86B shall not apply if the registered person has received a refund of more than one lakh rupees (₹1,00,000) in the preceding financial year on account of unutilized input tax credit under:
- Clause (i) of the first proviso to Section 54(3): Zero-rated supplies of goods or services made without payment of tax under bond or Letter of Undertaking (LUT); OR
- Clause (ii) of the first proviso to Section 54(3): Inverted duty structure (where the credit has accumulated on account of rate of tax on inputs being higher than the rate of tax on output supplies).
Exception 3: Cumulative Cash Tax Payment Exceeding 1% (Proviso Clause c)
Rule 86B shall not apply if the registered person has paid a cumulative amount of more than one per cent (1%) of the total output tax liability through the Electronic Cash Ledger up to the said month in the current financial year. The calculation is dynamic and cumulative across the financial year:
Cumulative Cash Percentage = (Total Cash Paid towards Output Tax from April to Current Month) / (Total Output Tax Liability from April to Current Month)
If an enterprise paid substantial cash taxes in April and May (e.g., 5% of its liability), and its cumulative cash percentage remains above 1.0% in November, it is exempt from Rule 86B in November, permitting 100% ITC utilization.
Exception 4: Government Entities and Public Sector Undertakings (Proviso Clause d)
Rule 86B is completely inapplicable if the registered person is: (a) a Government Department; (b) a Public Sector Undertaking (PSU); (c) a local authority; or (d) a statutory body established under an Act of Parliament or State Legislature.
Exception 5: Commissioner Discretionary Exemption (Proviso Clause e)
The Commissioner or an officer authorized by him in this behalf may remove the restriction after such verifications and safeguards as he may deem fit.
4. Interplay with Rule 86A: Blocking of Electronic Credit Ledger
While Rule 86B limits the percentage of output tax discharged via credit, Rule 86A arms the tax administration with summary powers to block the debit of credit lying in the Electronic Credit Ledger. Under Rule 86A(1), the Commissioner or an officer authorized by him (not below the rank of Assistant Commissioner) may disallow debit from the Electronic Credit Ledger if he has "reasons to believe" that credit has been fraudulently availed or is ineligible due to:
- The tax invoice was issued by a registered person who was non-existent or not conducting business from the registered premises;
- The credit was availed without actual receipt of goods or services;
- The tax charged in respect of the supply has not been paid to the Government under Section 16(2)(c);
- The registered person availing the credit is found non-existent or not conducting business from registered place; or
- The registered person is not in possession of a valid tax invoice or debit note.
Under Rule 86A(3), a statutory sunset clause applies: "Such restriction shall cease to have effect after the expiry of a period of one year from the date of imposing such restriction." Multiple High Courts have held that blocking an assessee's credit ledger without communicating the recorded "reasons to believe" in writing constitutes an arbitrary administrative act violating Article 19(1)(g) of the Constitution, warranting immediate judicial unblocking.
7 In-Depth Practical Case Studies & Numerical Illustrations
Case Study 1: Large Manufacturer Crossing ₹50 Lakh Monthly Taxable Turnover
Context & Facts: Bharat Auto Components Ltd is an automotive parts manufacturer in Pune. For the month of October 2025, the company's sales ledger discloses the following transactional breakdown:
- Domestic taxable sales of transmission gears: ₹65,00,000 (Applicable GST @ 18% = ₹11,70,000).
- Direct exports under LUT (zero-rated): ₹40,00,000 (Applicable GST = ₹0).
- Scrap sales to local recyclers: ₹8,00,000 (Applicable GST @ 18% = ₹1,44,000).
- Total Output Tax Liability for October: ₹11,70,000 + ₹1,44,000 = ₹13,14,000.
- Opening Electronic Credit Ledger Balance: ₹45,00,000 (Accumulated from capital equipment purchases).
Step-by-Step Rule 86B Applicability & Cash Tax Computation:
- Turnover Evaluation:
- Taxable domestic supply = ₹65,00,000 + ₹8,00,000 = ₹73,00,000.
- Zero-rated export supply = ₹40,00,000 (statutorily excluded from turnover calculation).
- Net Relevant Taxable Turnover = ₹73,00,000.
- Threshold Analysis: Because ₹73 Lakh exceeds the statutory threshold of ₹50 Lakh, Rule 86B is triggered for October 2025.
- Maximum Permissible Credit Utilization (99% Rule):
- Total Output Tax Liability = ₹13,14,000.
- Maximum ITC Utilization = 99% of ₹13,14,000 = ₹13,00,860.
- Mandatory Cash Ledger Payment (1% Rule):
- Minimum Cash Payment = 1% of ₹13,14,000 = ₹13,140.
- Bharat Auto Components must generate an electronic cash challan in Form GST PMT-06 and deposit ₹13,140 in cash, despite holding an unutilized ITC balance of ₹45 Lakh.
- GSTR-3B Table 6.1 Offset: The company offsets ₹13,00,860 from the Electronic Credit Ledger and ₹13,140 from the Electronic Cash Ledger. Filing GSTR-3B by attempting to offset 100% from credit causes an automatic portal validation error, blocking return submission.
Bharat Auto Components manages this monthly calculation using assureTax, which auto-generates the 1% PMT-06 challan seamlessly.
Case Study 2: Income Tax Exemption Test (> ₹1 Lakh Income Tax Paid by Managing Director)
Context & Facts: Zenon BioFuels Pvt Ltd is a green energy startup incorporated in 2023. In November 2025, its taxable turnover reaches ₹90,00,000 with an output tax liability of ₹16,20,000. Zenon BioFuels has accumulated ITC of ₹35,00,000. Because the startup incurred heavy initial depreciation and setup expenses, Zenon BioFuels paid zero income tax in FY 2023-24 and FY 2024-25. However, its founder and Managing Director, Mr. Rajesh Sharma, is a high-net-worth individual whose personal ITR disclosures reflect:
- AY 2024-25 (FY 2023-24): Total Income Tax Paid = ₹14,50,000.
- AY 2025-26 (FY 2024-25): Total Income Tax Paid = ₹18,20,000.
Statutory Interpretation under Proviso Clause (a):
- Under clause (a) of the proviso to Rule 86B, the exemption applies if "the registered person or the proprietor, or karta, or the managing director... have paid more than one lakh rupees as income tax under the Income-tax Act, 1961 in each of the last two financial years".
- The statute explicitly extends the exemption to income tax paid by the Managing Director personally.
- Because Mr. Rajesh Sharma (Managing Director) paid ₹14.5 Lakh and ₹18.2 Lakh in the last two financial years respectively (each exceeding ₹1,00,000), Zenon BioFuels Pvt Ltd satisfies the statutory safe-harbor exemption in full.
- Outcome: Zenon BioFuels is completely exempt from Rule 86B in November 2025. It can utilize its Electronic Credit Ledger to offset 100% of its ₹16,20,000 liability, preserving working capital. Zenon stores the MD's ITR-V filing proofs in assurePractice compliance repository.
Case Study 3: Exporter with Zero-Rated Supplies (Refund Exemption under Proviso Clause b)
Context & Facts: Global Tech Textiles LLP manufactures organic cotton garments. During FY 2024-25, the firm exported garments without payment of tax under LUT, receiving a statutory GST refund of unutilized accumulated ITC under Section 54(3)(i) of ₹18,50,000 in August 2024. In May 2025 (FY 2025-26), the firm entered the domestic market, recording domestic taxable sales of ₹75,00,000 with an output tax liability of ₹3,75,000 (GST @ 5%). The firm has an unutilized ITC balance of ₹12,00,000. The GST portal flags the return for mandatory 1% cash payment.
Application of Proviso Clause (b):
- Evaluation of Preceding Year Refund: In the preceding financial year (FY 2024-25), the firm received a formal refund order in Form GST RFD-06 for ₹18,50,000 on account of zero-rated supplies without payment of tax under Section 54(3).
- Monetary Threshold: The refund of ₹18,50,000 comfortably exceeds the statutory threshold of one lakh rupees (₹1,00,000).
- Exemption Invocable: Under clause (b) of the proviso to Rule 86B, the entity is exempt from the 99% cap throughout the entirety of FY 2025-26.
- Remedy: Global Tech Textiles overrides the portal cash prompt by selecting the statutory refund exemption check, offsetting 100% of its ₹3,75,000 output tax liability through its Electronic Credit Ledger.
Case Study 4: Cumulative Cash Payment Tracking across the Financial Year
Context & Facts: Apex Steel Distributors LLP operates a wholesale trading hub. The firm does not qualify for the income tax or refund exemptions. During FY 2025-26, its monthly taxable turnover, output tax liability, and cash tax payments are tracked dynamically:
| Month | Taxable Turnover | Output Tax Liability | Cash Tax Paid | Cumulative Output Tax | Cumulative Cash Paid | Cumulative Cash % | Rule 86B Status |
|---|---|---|---|---|---|---|---|
| April 2025 | ₹60,00,000 | ₹10,80,000 | ₹50,000 (Paid cash) | ₹10,80,000 | ₹50,000 | 4.63% | 1% Rule Complied |
| May 2025 | ₹80,00,000 | ₹14,40,000 | ₹20,000 | ₹25,20,000 | ₹70,000 | 2.78% | 1% Rule Complied |
| June 2025 | ₹75,00,000 | ₹13,50,000 | ₹10,000 | ₹38,70,000 | ₹80,000 | 2.07% | 1% Rule Complied |
| July 2025 | ₹90,00,000 | ₹16,20,000 | ₹0 (100% ITC used) | ₹54,90,000 | ₹80,00,000 | 1.46% | EXEMPT u/s Proviso (c) |
Analysis of July 2025 Exemption: In July 2025, the firm wished to utilize 100% ITC to discharge its ₹16,20,000 liability.
- Cumulative Output Tax up to July: ₹54,90,000.
- 1% Statutory Benchmark: 1% of ₹54,90,000 = ₹54,900.
- Actual Cumulative Cash Tax Paid from April to June: ₹80,000.
- Because ₹80,000 > ₹54,900 (cumulative cash percentage = 1.46%), the firm satisfies proviso clause (c).
- Outcome: In July 2025, Apex Steel pays ₹0 in cash and utilizes 100% ITC, because its cumulative cash contributions already exceed 1% of total liabilities.
Case Study 5: Rule 86A Credit Ledger Blocking without Written "Reasons to Believe"
Context & Facts: Matrix InfraTech Pvt Ltd holds an Electronic Credit Ledger balance of ₹1,80,00,000 (₹1.8 Crore). On 12th August 2025, the Assistant Commissioner issued an electronic order on the GST portal under Rule 86A blocking the entire credit ledger of ₹1.8 Crore. The order cited: "Input Tax Credit blocked on directions of Anti-Evasion Directorate pending investigation of supplier M/s Zenith Steels". No formal show cause notice, hearing, or specific written recording of "reasons to believe" was served on Matrix InfraTech.
Constitutional Challenge under Article 226:
- Statutory Mandate of Rule 86A: An officer can disallow debit from the credit ledger only if he has "reasons to believe" that credit was availed fraudulently or is ineligible under specified clauses, and these reasons must be recorded in writing in the official file.
- Jurisprudence: The Gujarat High Court in Valerius Industries v. Union of India and the Delhi High Court in Best Crop Science held that:
- Rule 86A confers drastic extraordinary powers that freeze working capital; it cannot be exercised mechanically or on third-party instructions without independent application of mind.
- The "reasons to believe" must be based on tangible material showing complicity or fraudulent intent on the part of the petitioner, not merely that a supplier is under routine inquiry.
- Blocking the entire ledger (₹1.8 Crore) when the disputed purchases from Zenith Steels totaled only ₹15 Lakh violates the doctrine of proportionality.
- Judicial Relief: The High Court quashes the blocking order, directing the immediate unblocking of the Electronic Credit Ledger within 24 hours. Matrix InfraTech logs this defense and unblocking order in assureNotice.
Case Study 6: Composition of Turnover: Mixed Taxable and Exempt Supplies
Context & Facts: Agro-Industrial Corp sells processed organic fertilizers (taxable @ 5%) and raw unprocessed food grains (wholly exempt from GST under Notification No. 2/2017-Central Tax). During September 2025, the company's GSTR-1 disclosures reflect:
- Outward supply of processed fertilizers (taxable): ₹42,00,000 (GST @ 5% = ₹2,10,000).
- Outward supply of raw grains (exempt): ₹60,00,000 (Nil GST).
- Total Aggregate Turnover in GSTR-1: ₹1,02,00,000 (₹1.02 Crore).
- Total Output Tax Liability: ₹2,10,000.
- Available ITC Balance: ₹8,00,000.
Legal Determination under Rule 86B:
- The opening text of Rule 86B explicitly qualifies the threshold: "in cases where the value of taxable supply other than exempt supply and zero-rated supply, in a month exceeds fifty lakh rupees".
- Total aggregate turnover is irrelevant. Only taxable supplies are counted.
- Taxable supply in September = ₹42,00,000. Exempt supply of ₹60,00,000 is statutorily excluded.
- Because ₹42,00,000 does NOT exceed ₹50,00,000, Rule 86B is inapplicable.
- Outcome: Agro-Industrial Corp can utilize its Electronic Credit Ledger to offset 100% of its ₹2,10,000 liability. The internal auditor's objection is legally incorrect.
Case Study 7: Portal Glitch Forcing Cash Payment: Rectification and Grievance Mechanics
Context & Facts: Precision Tools Ltd qualified for the income tax exemption under Proviso (a) (the company paid ₹12 Lakh corporate income tax in each of the last two financial years). However, when filing GSTR-3B for October 2025 with taxable turnover of ₹70 Lakh and tax liability of ₹10,00,000, the GST Common Portal algorithm malfunctioned: it grayed out the Electronic Credit Ledger offset field beyond ₹9,90,000, forcing the company to pay ₹10,000 in cash to submit the return before the 20th November deadline.
Procedural Rectification & Accounting Treatment:
- Immediate Filing to Avoid Late Fees: To prevent Section 47 late fees (₹50/day) and Section 50 interest, the company deposits ₹10,000 via PMT-06 and files GSTR-3B under protest.
- Lodge GST Self-Service Grievance: Precision Tools lodges an official technical ticket on the GST Grievance Redressal Portal, attaching copies of its last two ITR-V forms and balance sheets substantiating Proviso (a) eligibility.
- Accounting Rectification: In assureFinancials, the ₹10,000 cash payment is credited as a cash outflow and debited to 'GST Cash Ledger Advance'. In the subsequent month (November 2025), the company reduces its voluntary cash top-up by ₹10,000, consuming available ITC once the portal technical ticket resolves the backend master flag.
10-Step Rule 86B & Cash Ledger Verification Framework
To avoid return filing rejections on the 20th of every month and prevent illegal cash drain, tax controllers and chartered accountants must execute the following 10-step verification protocol.
| Stage | Procedural Mandate | Statutory Citation | Critical Operational Risk / Audit Trap | assureOffice Workflow Integration |

Integrating assureOffice Ecosystem for Cash Ledger Governance
Navigating Rule 86B cash payment mandates and defending against Rule 86A credit blocking orders demands continuous integration between tax computational engines and legal workflows. The assureOffice suite equips corporate finance and legal departments with comprehensive tools:
- assureTax: Acts as the primary tax computation engine. It dynamically monitors monthly taxable turnovers, tracks cumulative cash tax percentages across the financial year, applies Proviso (a) to (e) exemptions, and auto-generates Form GST PMT-06 cash challans to guarantee zero return filing delays.
- assureNotice: Centralizes the receipt and management of GST enforcement communications. It monitors electronic orders blocking the credit ledger under Rule 86A, tracks the strict 1-year statutory sunset countdown under Rule 86A(3), and archives official correspondence with anti-evasion directorates.
- assureFinancials: Automates corporate cash-flow forecasting, models the working capital impact of 1% cash tax requirements, and tracks accumulated input tax credit pools to evaluate the viability of applying for export or inverted duty structure refunds.
- assurePractice: Centralizes compliance master documentation. It archives director and entity ITR filings to substantiate Proviso (a) exemptions and facilitates the drafting of formal legal representations and High Court writ petitions to unblock illegally frozen credit ledgers.
16 Practical Practitioner FAQs with Authoritative Answers
1. When did Rule 86B come into effect?
Rule 86B was inserted via Notification No. 94/2020-Central Tax and came into effect on 1st January 2021.
2. What is the core restriction imposed by Rule 86B?
A registered person cannot use the Electronic Credit Ledger to discharge more than ninety-nine per cent (99%) of its output tax liability in a month where taxable supply exceeds ₹50 Lakh, compelling a minimum 1% payment in cash.
3. What turnover is considered for the ₹50 Lakh monthly threshold?
The threshold is based on the value of taxable supplies in that specific month, strictly excluding exempt supplies and zero-rated export supplies.
4. Are zero-rated supplies under Letter of Undertaking (LUT) included in the ₹50 Lakh limit?
No. Zero-rated supplies are explicitly excluded from the calculation of the ₹50 Lakh threshold under Rule 86B.
5. What is the Income Tax exemption under Proviso (a) to Rule 86B?
The rule does not apply if the registered person or its proprietor, Karta, Managing Director, or any two whole-time directors/partners have paid more than ₹1,00,000 as income tax in each of the last two financial years.
6. Can income tax paid by a Managing Director exempt a private limited company from Rule 86B?
Yes. Proviso (a) explicitly provides that if the Managing Director paid more than ₹1 Lakh income tax in each of the last two financial years, the company is exempt from Rule 86B.
7. What is the Refund exemption under Proviso (b) to Rule 86B?
The rule does not apply if the registered person has received a refund exceeding ₹1,00,000 in the preceding financial year on account of unutilized ITC from zero-rated supplies or inverted duty structure.
8. How does the Cumulative Cash Payment exemption under Proviso (c) work?
If the registered person has paid more than 1% of its total output tax liability cumulatively through the Electronic Cash Ledger up to the relevant month in the current financial year, it is exempt from Rule 86B for that month.
9. Does Rule 86B apply to Public Sector Undertakings (PSUs) and Government Departments?
No. Proviso (d) explicitly exempts Government Departments, Public Sector Undertakings, local authorities, and statutory bodies from Rule 86B.
10. Can the 1% cash tax payment be paid using Input Tax Credit?
No. By definition, the 1% payment must be discharged exclusively through the Electronic Cash Ledger using cash deposited via Form GST PMT-06.
11. What is the difference between Rule 86A and Rule 86B?
Rule 86A allows tax officers to block specific fraudulent ITC balances in the credit ledger for up to one year, whereas Rule 86B is an automated rule capping monthly ITC utilization at 99% for high-turnover taxpayers.

No. Multiple High Courts have held that recording "reasons to believe" in writing based on tangible material is a mandatory jurisdictional prerequisite. Blocking without recorded reasons is illegal and void.
14. Can an officer block more credit than the disputed fraudulent invoice amount under Rule 86A?
No. The power under Rule 86A is restricted to disallowing debit of an amount equivalent to the credit believed to be fraudulent. Freezing the entire credit ledger beyond the disputed amount violates the doctrine of proportionality.
15. Does Rule 86B apply to composition dealers?
No. Composition dealers pay tax under Section 10 and do not avail or utilize Input Tax Credit. Rule 86B applies only to regular taxpayers filing Form GSTR-3B.
16. What constitutional remedy is available if the portal forces cash payment despite qualifying for an exemption?
If the GST portal algorithm fails to recognize a legitimate statutory exemption under the provisos and the taxpayer is forced to deposit cash under protest, the taxpayer can file a writ petition under Article 226 of the Constitution before the High Court for systemic rectification and refund.
