Who can claim the patent-royalty deduction?
A resident individual who meets the statutory definition of patentee can claim the lower of qualifying royalty income and ₹3,00,000 under section 152, subject to the reporting, receipt and regime conditions. The patent must have been registered on or after 1 April 2003 under the Patents Act, 1970. Ownership of patent rights alone is insufficient: the income-tax definition focuses on the true and first inventor recorded as patentee, including qualifying joint patentees.
This guide applies to tax year 2026–27 under the Income-tax Act, 2025 as amended by Finance Act, 2026, checked on 23 October 2026. The legacy deduction commonly called section 80RRB should not be copied into a current return without checking the new provision and forms. This is a deduction for qualifying individual royalty income, not a concessional corporate patent-tax rate or a transfer-pricing rule.
Read the patent register before reading the bank receipt
Section 152(8) supplies its own definitions. Match the claimant to the register entry showing the true and first inventor. An assignee who purchased the commercial rights should not assume that being recorded as an owner satisfies this narrower tax definition. For joint inventors, establish each person’s recorded status and actual income entitlement; do not divide a receipt equally merely because several names appear on the patent.
Keep the patent registration date distinct from the invention date, licence execution date and date of the first sale. The eligibility window tests registration on or after 1 April 2003. A royalty agreement entered into recently cannot, by itself, repair a patent registered before that boundary.
Separate royalty from the other receipts in the commercial agreement
The definition covers specified consideration for patent rights or licensing, information about working or using the patent, use of the patent and connected services. It excludes consideration that is chargeable as capital gains, and sale proceeds of products manufactured using the patented process or of patented articles for commercial use. A royalty label on an invoice does not settle the character of the receipt.
A lump-sum receipt is not automatically excluded merely because it is a lump sum: the statutory definition includes non-returnable royalty advances. The real question remains whether the receipt is qualifying royalty income or, for example, excluded capital-gains consideration. Analyse the agreement, rights transferred and applicable income computation before applying the cap.
| Receipt/control | Section 152 working | Evidence |
|---|---|---|
| Ordinary qualifying royalty | Use the qualifying income included in gross total income | Licence, royalty schedule and income-head computation |
| Compulsory licence | Respect the royalty ceiling settled by the Controller | Controller’s licence terms and amount reconciliation |
| Foreign-source royalty | Apply the convertible-foreign-exchange receipt condition | Bank certificate, receipt date and any valid extension |
| Product sales or capital-gains consideration | Exclude from this section’s royalty base | Separate invoices and documented income character |
Apply income limits and foreign-realisation conditions in sequence
Begin with income properly computed and included in gross total income, not an unreconciled gross collection figure. Apply the special compulsory-licence restriction where relevant, and aggregate the qualifying amounts before the ₹3 lakh individual annual ceiling. The limit is not a separate allowance for every licence or patent. Do not import the percentage-of-book-sales restriction of the separate author-royalty provision into patent royalties.
For foreign-source income, section 152(4) limits the eligible amount to income brought into India in convertible foreign exchange within six months after the tax-year end, unless the competent authority allows further time. A customer’s foreign payment advice is not necessarily evidence of receipt in India. Reconcile the remittance to the particular royalty and retain any actual extension order; an application for extension is not the same as an approved extension.
The deduction is unavailable under section 202’s default regime because section 152 is not among its permitted Chapter VIII exceptions. A valid option for the regime allowing the deduction must therefore be established. Compare the complete computation before selecting a regime; a ₹3 lakh deduction is not a ₹3 lakh tax saving. Section 152 also prevents another deduction for the same income once a claim here has been allowed.
Form 37 establishes the patent details; Form 38 supports foreign receipt
Under the Income-tax Rules, 2026, Rules 71–72 and Forms 37–38, Form 37 is the patent-royalty certificate. The Income Tax Department’s Form 37 FAQ explains the patentee’s declaration and the independent certification by the Controller of Patents. The claimant’s self-declaration does not replace that certification. Follow the prescribed electronic process and applicable deadline; the FAQ specifies filing on or before the applicable return due date.
Foreign-source claims also need the prescribed inward-remittance certificate in Form 38. Keep its transaction identity, currency, rupee equivalent and bank certification linked to the foreign royalty schedule. The certificate supports the receipt condition; it does not establish that the recipient is the statutory inventor or that a capital receipt is royalty.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: Qualifying income below the ceiling
Assume a resident individual inventor, a qualifying 2018 patent, complete certificates, the permitting regime and sufficient deduction headroom. Properly computed qualifying royalty income is ₹2,40,000. The section 152 deduction is min(₹2,40,000, ₹3,00,000) = ₹2,40,000. No final tax or cess is calculated here.
Illustrative example 2: Two patents share one individual cap
Qualifying royalty income from two eligible patents is ₹1,80,000 and ₹1,70,000. Aggregate income is ₹3,50,000. The individual’s section 152 deduction is ₹3,00,000, not ₹3,50,000 or two separate ₹3 lakh allowances. The cap excludes ₹50,000 from this deduction.
Illustrative example 3: Patent-registration boundary
Two separate otherwise eligible inventors each have ₹1,20,000 qualifying royalty income. Their patents were registered on 1 April 2003 and 31 March 2003 respectively. Under the stated statutory date test, their section 152 deductions are ₹1,20,000 and zero. A later licence date does not change the earlier patent’s registration date.
Illustrative example 4: Compulsory-licence ceiling comes first
Assume royalty income of ₹3,60,000 is included in the computation, but the Controller-set compulsory-licence terms support only ₹2,80,000 for the deduction. The base is restricted to ₹2,80,000; the ₹3 lakh annual cap does not increase it. The section 152 deduction is ₹2,80,000, leaving ₹80,000 outside this deduction on those facts.
Illustrative example 5: Domestic and foreign-source aggregation
Assume domestic qualifying income of ₹1,80,000 and foreign qualifying income of ₹2,40,000, with no expense or exchange-rate complication. Only ₹1,50,000 of the foreign amount is brought into India in convertible foreign exchange by 30 September 2027, the ordinary six-month deadline after 31 March 2027; no extension exists. Eligible aggregate is ₹3,30,000 and the capped deduction is ₹3,00,000. The unremitted ₹90,000 does not enter the eligible base merely because it is taxable income.
Illustrative example 6: Default regime blocks an otherwise valid amount
An otherwise eligible inventor has ₹2,70,000 qualifying royalty income but remains in the default regime under section 202. The section 152 claim under that regime is zero. An effective permitting-regime option would change the deduction eligibility, but the preferable total-tax outcome needs a separate computation.
Illustrative example 7: A combined commercial receipt needs classification
An agreement produces ₹2,00,000 chargeable as capital gains, ₹1,80,000 proceeds from sale of patented products and ₹1,00,000 qualifying royalty income. Total receipts are ₹4,80,000, but the stated qualifying royalty base is ₹1,00,000. Assuming all other conditions, section 152 deducts ₹1,00,000; the other ₹3,80,000 is not transformed into eligible royalty by the agreement’s title.

Sixteen practitioner FAQs
1. Can a company claim this individual deduction?
No. Section 152’s claimant population is a resident individual satisfying its other conditions. Corporate patent income requires a different statutory analysis.
2. Does every patent owner satisfy the patentee definition?
No. Check the narrower true-and-first-inventor definition, including qualifying recorded joint inventors. A purchaser of rights should not assume ownership alone is sufficient.
3. What patent date matters?
Registration on or after 1 April 2003 under the Patents Act. A recent royalty agreement does not substitute for the required registration date.
4. Can a joint inventor qualify?
The definition includes qualifying joint patentees recorded as true and first inventors. Establish individual income entitlement and conditions rather than automatically splitting the deduction equally.
5. Are patented-product sales royalty?
The specified product-sale consideration is excluded from the royalty definition for this section. Maintain a separate sales schedule even if the buyer also pays licence fees.
6. Is a lump-sum royalty always ineligible?
No. The section’s definitions recognise lump sums, including non-returnable royalty advances. Characterise the receipt correctly, especially where capital-gains treatment may apply.
7. Is the ₹3 lakh cap per patent?
No. Aggregate qualifying income for the individual for the tax year and apply the single section 152 ceiling.
8. Does the author-royalty 15% sales test apply here?
Do not import the separate author-royalty computation into patent royalties. Section 152 contains its own conditions, including the compulsory-licence restriction.
9. What does a compulsory licence change?
The deductible royalty base cannot exceed the amount under the Controller-set licence terms. Apply that restriction before the annual deduction ceiling.
10. Is foreign-source royalty eligible when still overseas?
Only the amount meeting the prescribed convertible-foreign-exchange receipt condition and timing can enter this deduction, subject to a valid further period if allowed.
11. What is the ordinary receipt window for 2026–27?
Six months after the 31 March 2027 tax-year end, ordinarily ending 30 September 2027. Retain evidence for any competent-authority extension actually granted.
12. Can an extension request be treated as approval?
No. Keep the actual approval and its permitted period. Do not enlarge the eligible base from a pending request alone.
13. Who certifies the patent particulars in Form 37?
The official FAQ describes the patentee’s declaration and independent Controller of Patents certification. A self-declaration alone does not complete both functions.
14. Does Form 38 replace Form 37?
No. The foreign-remittance certificate and the patent-royalty certificate establish different elements of the claim.
15. Can the default-regime taxpayer still claim section 152?
Section 202’s permitted Chapter VIII exceptions do not include section 152. Establish a valid regime position before inserting the deduction.
16. Can the same income support a second deduction elsewhere?
Section 152 bars another deduction for income already allowed here, including in another tax year. Reconcile overlapping incentive claims before filing.
