Tax on Income from Patents in India Under New ITA 2025
Introduction
A patent can generate income when an inventor licenses it, permits its use, transfers specified rights, or provides technical information about the invention. For Indian inventors, the tax on income from patents may be lower than the normal rate when every statutory condition is satisfied.
Section 194(1), Table Serial Number 2 of the Income-tax Act, 2025 provides a 10% rate for qualifying royalty from a patent developed and registered in India.
Quick Insights
- Eligible tax on income from patents is charged at 10% on gross qualifying royalty.
- The claimant must be resident in India and satisfy the special definition of patentee.
- At least 75% of patent development expenditure must be incurred in India.
- No expenditure or allowance can be deducted from royalty taxed at the special rate.
- Form 65 must be filed by the applicable income tax return due date.
Legal Basis for Tax on Income from Patents
The provision for tax on income from patents is Section 194 of the Income-tax Act, 2025. It applies when an eligible assessee earns royalty from a patent developed and registered in India. Qualifying royalty is taxed at 10%, while the taxpayer’s remaining income is taxed under the other applicable provisions.
The Income-tax Act, 2025 came into force on April 1, 2026. The corresponding provision under the Income-tax Act, 1961 was Section 115BBF. Older guidance may therefore refer to Section 115BBF and Form 3CFA, while current compliance refers to Section 194 and Form 65.
The Patent Box Regime in India is optional and does not apply to every intellectual property receipt.
What Is Patent Royalty Income?
For calculating tax on income from patents, royalty includes consideration for transferring all or any rights in a patent, including granting a licence. It covers payments for providing information about the working or use of a patent, permitting its use, or providing connected services.
A lump-sum amount, including a non-refundable royalty advance, may also qualify. The agreement’s title is not conclusive because the actual rights, payment terms, and obligations determine the nature of the receipt. Ebizfiling further explains why a patent is an asset to its owner.
The tax on income from patents must therefore follow the real commercial arrangement, not merely labels such as licence fee or assignment fee.
Who Can Claim the 10% Rate?
The concessional tax on income from patents is available only to an eligible assessee who is resident in India and qualifies as a patentee under Section 194.
For this provision, the claimant must be the true and first inventor whose name is entered in the patent register as the patentee. If several people are registered, each claimant must satisfy requirements. A person who merely purchases or receives an assignment of a patent may not qualify for tax on income from patents.
The Patents Act, 1970 generally defines a patentee as the registered grantee or proprietor. Section 194 imposes a narrower requirement for tax on income from patents by also linking eligibility with true and first inventorship. A first importer or a person who merely receives an invention communicated from outside India is not treated as the true and first inventor.
Residential status, inventorship, ownership, and register entries should be verified before claiming the benefit.
Patent Developed and Registered in India
The special tax on income from patents applies only when royalty relates to a patent developed and registered in India. A patent is treated as developed in India when at least 75% of the expenditure incurred by the eligible assessee for developing the invention was incurred in India.
The taxpayer should keep research payroll, laboratory invoices, prototype expenses, testing costs, contracts, and payment records. The patent must be granted under the Patents Act, 1970, so a foreign patent alone does not satisfy the condition.
Where royalty relates to patents registered in several countries, the amount attributable to the qualifying Indian patent should be separately identified before calculating tax on income from patents.
India’s patent system continues to be governed by the Patents Act, 1970 and the Patents Rules, 2003, as amended. The electronic version of the Patents Rules available on the IP India portal incorporates the 2024 amendments.
Rate and Calculation of Tax on Income from Patents
Qualifying tax on income from patents is calculated at 10% of gross royalty. Applicable surcharge and health and education cess are added separately. Health and education cess is charged at 4% of income tax and surcharge.
No expenditure or allowance is deductible from royalty taxed under the special provision. Research costs, patent renewal fees, legal expenses, employee costs, and licensing expenses cannot be reduced from gross qualifying royalty.
For example, on qualifying royalty of ₹20,00,000, tax at 10% is ₹2,00,000. If no surcharge applies, 4% cess is ₹8,000. The total tax on income from patents is ₹2,08,000 before TDS credit.
The patent royalty tax in India may be beneficial when the normal rate is higher, but the concessional rate applies to gross royalty.
Income Excluded from the 10% Rate
Not every patent-related receipt qualifies for tax on income from patents at 10%. The statutory royalty definition excludes consideration chargeable under the head “Capital gains.” A complete sale or permanent transfer of a patent may therefore require a separate capital gains analysis.
The law also excludes consideration from selling a product manufactured using a patented process and consideration from selling a patented article for commercial use. Business revenue does not become qualifying royalty merely because a patent protects the product or process.
The benefit may also be unavailable to a non-resident, a claimant who does not satisfy the inventor and patentee conditions, or a person who fails the 75% expenditure test.
For correct patent royalty tax in India, licensing receipts should be separated from product sales, unrelated services, reimbursements, and capital receipts.
Patent Licence Versus Complete Patent Sale
A licence normally allows another person to use specified patent rights while ownership remains with the patentee. Payments under a genuine licensing arrangement may qualify for concessional tax on income from patents.
A complete sale generally transfers ownership permanently and may result in capital gains. The agreement should state the rights transferred, territory, duration, exclusivity, payment method, termination terms, and continuing obligations.

Form 65 Filing for Tax on Income from Patents
Rule 134 of the Income-tax Rules, 2026 prescribes Form 65 for opting for the special tax on income from patents. It replaces Form 3CFA used under the earlier framework.
Form 65 must be furnished on or before the due date for filing the return under Section 263(1) for the relevant tax year. It must be submitted electronically using a digital signature certificate or electronic verification code, as applicable.
The form requires residential status, tax year, patent number, grant date, patent description, royalty income, and development expenditure. Each eligible patent must be reported separately, along with information supporting the 75% Indian development expenditure condition.
Five-Year Continuity Condition
After exercising the option, the taxpayer is expected to offer eligible royalty under the special tax on income from patents for the next five tax years.
If the provision is not followed in any of those five succeeding tax years, the taxpayer becomes ineligible for the benefit for five tax years following the year of default. The long-term effect should be reviewed before opting for the Patent Box Regime in India.
TDS on Patent Royalty
TDS and final tax on income from patents are separate. Royalty paid to a resident may be subject to tax deduction at source under the applicable provisions, depending on the payer, payment, threshold, and other statutory conditions.
The recipient may claim credit for correctly reported TDS. However, TDS does not itself establish eligibility for the 10% Patent Box rate, and Form 65 remains necessary.
Businesses responsible for deduction and reporting can use our TDS return filing service for challan reconciliation and filing support.
Records Required for Tax on Income from Patents
A taxpayer claiming tax on income from patents should maintain patent-wise records, including the grant certificate, register details, proof of inventorship, licence agreement, royalty invoices, bank statements, development expenditure records, and TDS documents.
A separate working should show gross royalty, Indian development expenditure, and the 75% calculation while excluding product revenue, unrelated services, and capital gains.
Mistakes to Avoid in Patent Taxation
The most common errors include claiming the benefit as a patent purchaser who is not the inventor, applying the rate to sales of patented products, deducting expenses from gross royalty, and failing to prove Indian development expenditure.
Taxpayers may also miss the Form 65 deadline, combine Indian and overseas patent income, treat a complete assignment as royalty, or overlook the five-year continuity rule. These mistakes can invalidate the claim for tax on income from patents under Section 194.

Conclusion
The concessional tax on income from patents encourages Indian research and innovation by applying a 10% rate to qualifying gross royalty. It is available only to an eligible resident patentee receiving royalty from a patent developed and registered in India.
A valid claim requires correct royalty classification, proof that at least 75% of development expenditure was incurred in India, timely Form 65 filing, and compliance with the five-year continuity condition. Careful documentation is essential because tax on income from patents does not cover capital gains, patented-product sales, or every payment associated with intellectual property.
Frequently Asked Questions
1. Is advance tax payable on patent royalty income?
Yes. Advance tax may apply if the estimated tax liability for the year is ₹10,000 or more after considering eligible tax credits. Patent owners receiving periodic or lump-sum royalties should estimate and pay advance tax within the prescribed instalment dates.
2. Is patent royalty taxed when invoiced or received?
It depends on the taxpayer’s regularly followed accounting method. Under the cash system, royalty is generally recognised when received. Under the mercantile system, it may be recognised when the right to receive the income arises.
3. How is patent royalty received in foreign currency reported?
Foreign patent royalty must be converted into Indian rupees using the applicable exchange rate prescribed under tax rules. Any separate foreign exchange gain or loss may also need to be considered while calculating taxable income.
4. What happens if royalty is received after the patent expires?
Royalty received after expiry may still relate to the use of the patent during its valid term. The licensing agreement and payment period must be reviewed to determine whether the receipt continues to qualify as patent royalty.
5. Are damages received for patent infringement taxed at 10%?
Not automatically. Compensation or damages awarded for patent infringement may not qualify as royalty. Their tax treatment depends on the court order, settlement agreement, and the actual nature of the payment.
6. How is royalty divided between joint patent owners?
Royalty is generally divided according to the ownership agreement and each owner’s entitlement. Every co-owner claiming the concessional tax rate must independently satisfy the residency, inventorship, registration, and expenditure conditions.
7. Can royalty received under a compulsory licence qualify for the 10% rate?
It may qualify if the payment relates to the permitted use of an eligible Indian patent and the recipient satisfies all conditions under Section 194 of the Income-tax Act, 2025.
8. Can royalty earned through a sublicense qualify as patent royalty?
Yes, it may qualify when the original licence permits sublicensing and the payment is directly linked to the use or transfer of patent rights. Payments for technical support, trademarks, or other services should be separated.
9. Can Ebizfiling help calculate advance tax on patent royalty?
Yes. Ebizfiling can review royalty receipts, TDS credits, foreign tax records, and other taxable income to estimate advance tax liability and support the applicable income tax return filing.
10. Can Ebizfiling assist with tax compliance for jointly owned patents?
Yes. Ebizfiling can review the patent register, ownership agreement, royalty-sharing terms, invoices, and expenditure records before tax filing. Inventors can also use its patent application and registration service to protect new inventions in India.
