What Is Section 80RRB?

Section 80RRB is a tax deduction under the Income Tax Act, 1961, which allows royalty income from patents to be partially tax-free.

In short: If you’re a patent holder and receive royalty income, you may be eligible to reduce tax on that income under 80RRB.

Who Can Claim 80RRB?

To use this deduction, you must meet these eligibility conditions:

• You must be a resident individual in India. 
• You must be the patentee (or co-owner/original patent-holder). 
• The patent must be registered under the Patents Act, 1970, and registration date should be on or after 1 April 2003. 
• The royalty must be included in your gross total income for that assessment year.

Also note: this deduction is available under the old tax regime — not the newer simplified slab system. 

What Is The Deduction Limit under 80RRB?

Here’s how much you can reduce:

The maximum deduction allowed under Section 80RRB is ₹ 3,00,000 in a year. But you can only deduct up to the amount of royalty you receive. If your royalty is less than ₹ 3,00,000, you claim that exact amount. If it’s more, you can deduct only ₹ 3,00,000. 

So it’s “less than royalty income or 3 lakh”.

Example: How 80RRB Works

Imagine Dr. Meera, a researcher in Bengaluru, who holds a patent registered in India after 2003. She earns ₹ 4,20,000 as royalty income for one financial year from that patent.

Because the limit is ₹ 3,00,000, she can claim deduction up to ₹ 3,00,000. That means ₹ 1,20,000 (4.2 lakh – 3 lakh) of the royalty remains taxable.

She files her ITR under the old regime, submits required certificates (Form 10CCE), and reduces her taxable income by ₹ 3,00,000.

Things To Consider

• You must furnish the prescribed certificate (Form 10CCE or similar) along with your income tax return. 
• Foreign royalty payments are considered only if brought into India within prescribed time (about six months after year end) in convertible foreign currency.
• Once you claim deduction for a royalty item under 80RRB, you cannot claim another deduction for same income under any other section. 

Why It Matters

If you are a patent-holder earning royalty income, Section 80RRB gives you tax-saving power, instead of paying tax on the entire royalty, you reduce your taxable portion by up to ₹ 3 lakh. For inventors or innovators, that could translate into serious annual savings.
