Section 80RRB: Income Tax Deduction on Patent Royalty

What is Section 80RRB?

Section 80RRB is a deduction provision in Chapter VI-A of the Income-tax Act, 1961 for certain income received by a resident individual who is the inventor and registered patentee of a qualifying patent. It was introduced to encourage innovation and reward inventors for licensing or otherwise commercially exploiting their inventions.

The deduction is not a blanket tax exemption for all intellectual property earnings. It applies only to royalty as defined in the provision, from a patent registered on or after 1 April 2003 under the Patents Act, 1970, and subject to the other statutory conditions.

Who can claim the deduction under Section 80RRB(1)?

• The taxpayer must be an individual resident in India for the relevant previous year.
• The individual must be a patentee, meaning the true and first inventor whose name is entered in the patent register; joint inventor-patentees can qualify individually if the conditions are met.
• The royalty must arise from a patent registered on or after 1 April 2003 under the Patents Act, 1970.
• The individual's gross total income must include qualifying royalty income.
• The prescribed certificates and, for foreign-source royalty, the additional remittance conditions must be met.

A company, a mere patent assignee who is not the true and first inventor, or a person earning ordinary product-sale receipts does not qualify solely because it owns or uses a patent.

How much deduction is allowed?

Under Section 80RRB(1), the deduction equals 100% of eligible royalty income or Rs. 3,00,000, whichever is lower, subject to the relevant Chapter VI-A computation rules.

These are simplified illustrations assuming the entire stated amount is eligible royalty and no other restrictions reduce the allowable deduction. The ceiling is a taxpayer-level statutory limit, not an automatic Rs. 3 lakh deduction for every patent.

Compulsory licences

Where a compulsory licence is granted under the Patents Act, the royalty considered for the deduction cannot exceed the royalty amount determined under the licence terms settled by the Controller under that Act.

What qualifies as royalty for Section 80RRB?

For this section, royalty generally means consideration, including qualifying non-returnable lump-sum payments, for:

• Transfer of all or some rights in a patent, including a licence;
• Providing information about the working or use of a patent;
• Use of a patent; or
• Services connected with those patent-related activities.

The definition excludes consideration chargeable as capital gains and proceeds from the commercial sale of products made using a patented process or of patented articles. Thus, sales revenue is not automatically patent royalty.

Foreign-source patent royalty and remittance

Under the second proviso to Section 80RRB(1), foreign-source royalty counts only to the extent it is brought into India in convertible foreign exchange by or on behalf of the taxpayer within six months from the end of the relevant previous year, or within a longer period permitted by the competent authority.

The competent authority is identified by reference to the Explanation to Section 80QQB, including the Reserve Bank of India or another legally authorised foreign-exchange authority. Supporting evidence of the inward remittance and the prescribed certificate for foreign-source income should be retained. See the Reserve Bank of India for foreign-exchange guidance.

Certificates and return filing: Section 80RRB(2) and (3)

The law requires a certificate in the prescribed form, signed by the prescribed authority, containing the relevant particulars. Form 10CCE is the prescribed certificate for Section 80RRB under the Income-tax Rules, 1962. Where income is earned outside India, an additional prescribed certificate and relevant remittance documentation are required under the applicable rules.

Check the filing procedure and form availability on the official Income Tax e-Filing Portal. The statutory requirement should be read together with applicable electronic filing rules and judicial guidance for the year concerned.

No double deduction: Section 80RRB(4)

If the taxpayer has claimed and been allowed a deduction for the same royalty income under Section 80RRB for a previous year, no deduction for that income can be allowed again under another provision of the Income-tax Act, 1961 in any assessment year.

Important legal definitions

Patent: A patent, including a patent of addition, granted under the Patents Act, 1970.

Patentee: A person who is the true and first inventor and whose name is entered on the patent register as patentee; it includes each qualifying joint inventor entered as a patentee.

Patent of addition: A patent relating to an improvement or modification, as defined in the Patents Act, 1970.

Controller: The Controller as defined under the Patents Act, 1970, relevant in compulsory-licence cases.

Lump sum: Includes a non-returnable advance payment on account of royalty.

True and first inventor: The expression has the meaning assigned under Section 2(1)(y) of the Patents Act, 1970.

Section 80RRB and the law from April 2026

The Income-tax Act, 2025 took effect from 1 April 2026. The historical section number 80RRB belongs to the Income-tax Act, 1961. For earlier assessment years, the 1961 Act and its relevant amendments continue to be important for assessment, rectification, appeals and disputes.

For tax year 2026-27 and later, consult the corresponding deduction provisions of the 2025 Act and the applicable tax regime. Under the optional new tax regime framework in the 1961 Act, many Chapter VI-A deductions, including Section 80RRB, were not available; the choice of tax regime therefore matters when assessing older-year claims.
