DTAA Relief Calculator
If your India income is also taxed in your country of residence, a tax treaty (DTAA) stops you paying twice — either by capping the tax India deducts at source, or by giving credit for it in your home country. This calculator models both the credit and exemption methods and shows how much you save versus being taxed in full by both countries. Updated for FY26.
Credit method: income taxable in both countries; your residence country credits the India tax — you effectively pay the higher rate, once. (Most treaties, incl. India-US, India-UK.)

What a DTAA actually does
Without a treaty, income you earn in India can be taxed by India (where it arises) and again by your country of residence (which taxes your global income) — the same rupee taxed twice. A Double Taxation Avoidance Agreement, which India has with more than 90 countries, prevents that. It works two ways, and it's worth understanding both because they solve different problems.
First, a treaty often caps the rate India can charge at source on certain income — interest, dividends and royalties especially. If your treaty caps interest at, say, a lower rate than India's domestic rate, you can have the Indian bank deduct at the treaty rate instead of the full domestic figure. Second, your residence country gives relief for the India tax — either a credit against its own tax, or an outright exemption of the income.
Credit vs exemption method
Most treaties, including India-US and India-UK, use the credit method. The income is taxable in both countries, but your residence country credits the tax already paid in India. The practical result: you pay the higher of the two rates, but only once. If India taxes ₹1,00,000 of interest at the treaty rate and your home country would tax it more, you pay India's tax plus the top-up to reach your home rate — never both in full.
Under the exemption method, the income is taxed in only one country and left out entirely by the other. Which method and which country gets to tax depends on your treaty and the type of income. The calculator lets you switch between them to see the difference for your numbers.
Worked example
You're an NRI in a country that taxes this income at 25%. You earn ₹10,00,000 of interest from an Indian NRO deposit. India's domestic rate would be about 30%, but your treaty caps interest at 15%.
India deducts at the treaty rate: 15% of ₹10,00,000 = ₹1,50,000. Your residence country taxes at 25% = ₹2,50,000, but credits the ₹1,50,000 paid in India, leaving ₹1,00,000 to pay there. Total tax: ₹2,50,000 — the higher rate, once. Without the treaty you'd have paid ₹3,00,000 in India (30%) plus ₹2,50,000 abroad with no credit — up to ₹5,50,000. The DTAA saves you the double hit.
How to claim DTAA relief
Relief is not automatic. To have India apply the treaty rate at source, give the Indian payer (your bank, company or tenant's deductor) two documents: a Tax Residency Certificate (TRC) from your country of residence, and Form 10F, filed on the Indian income tax e-filing portal. With these, the payer deducts at the treaty rate. Without them, the payer must apply the full domestic rate, and your only route is to claim relief when you file your Indian return — recovering the excess as a refund.
Keep the TRC current (it's usually annual), file Form 10F for each relevant year, and retain proof of the foreign tax paid if you're claiming a credit. For income already over-deducted, the fix is the same as elsewhere in NRI tax: file a return, or apply for a Form 13 lower-deduction certificate in advance.
Common mistakes to avoid
The biggest is simply not claiming — many NRIs let India deduct the full domestic rate on NRO interest and never file to recover the treaty difference. The second is using a treaty rate from the wrong country or wrong income type; every treaty and every income article (interest, dividends, royalties, capital gains) has its own rate, so read yours. The third is missing the TRC or Form 10F and then wondering why the payer applied the full rate. And the fourth is assuming DTAA covers capital gains — many treaties leave gains fully taxable in India, so check the capital-gains article specifically and pair this with the NRI capital gains calculator.
Glossary+
- DTAA
- Double Taxation Avoidance Agreement — a tax treaty between India and another country that prevents the same income being taxed twice.
- Credit method
- The residence country taxes the income but gives a credit for tax paid in India. Net effect: you pay the higher of the two rates, once.
- Exemption method
- The income is taxed in only one country and exempt in the other.
- TRC
- Tax Residency Certificate — proof from your country of residence that you're a tax resident there. Required to claim treaty benefits in India.
- Form 10F
- A form filed on the Indian income tax portal, alongside the TRC, to claim DTAA benefits.
- Treaty rate
- The maximum rate a DTAA allows the source country (India) to tax a given type of income — often lower than the domestic rate.
Frequently Asked Questions
What is DTAA relief? +
A Double Taxation Avoidance Agreement (DTAA) is a treaty between India and another country that stops the same income being taxed twice. It helps two ways: it can cap the tax India deducts at source (for example, treaty rates on interest are often lower than India's domestic rate), and it lets your country of residence give credit for tax you've already paid in India (or exempt the income). India has DTAAs with over 90 countries.
What's the difference between the credit and exemption methods? +
Under the credit method (used by most treaties, including India-US and India-UK), the income is taxable in both countries, but your residence country gives a credit for the tax paid in India — so you effectively pay the higher of the two rates, once. Under the exemption method, the income is taxed in only one country and exempt in the other. Which applies depends on your treaty and the type of income; the calculator lets you model both.
How does a DTAA cap the tax deducted in India? +
Many treaties set a maximum rate India can charge on certain income — commonly interest, dividends and royalties. If the treaty rate is lower than India's domestic TDS rate, you can have India deduct at the lower treaty rate instead, provided you furnish a Tax Residency Certificate and Form 10F. For example, interest that India would otherwise tax at a high domestic rate may be capped at a lower treaty rate. Always check your specific treaty for the exact figure.
What do I need to claim DTAA relief? +
Two documents are essential: a Tax Residency Certificate (TRC) from your country of residence proving you're a tax resident there, and Form 10F filed on the Indian income tax portal. For interest and similar income, you also give these to the Indian payer (bank/company) so they apply the treaty rate at source. Without the TRC and Form 10F, the payer applies the full domestic rate and you can only claim relief later by filing a return.
Which treaty rate should I enter? +
Use the rate from the specific India–[your country] treaty for your type of income. Treaty rates vary by country and income type (interest, dividends, royalties, capital gains each have their own article). The exact rates are in the treaty text on the Income Tax Department's website. This calculator does not assume a rate for you — enter your treaty's figure so the result is accurate for your situation.
Does DTAA help with capital gains? +
Sometimes. A few treaties historically gave favourable capital-gains treatment (India-Singapore, India-Mauritius), though 2017 grandfathering rules limit this for newer investments. Many treaties leave capital gains taxable in India regardless. Check your treaty's capital-gains article specifically — and for Indian equity/mutual fund gains, use the NRI capital gains calculator alongside this one.
