That's where DTAA comes in.
DTAA stands for Double Taxation Avoidance Agreement. It's a treaty between two countries that decides who gets to tax what, and by how much. India has signed DTAAs with 95+ countries. If you live in one of those countries, you can use the treaty to either reduce your tax or get credit for tax already paid.
Here's the thing. Most NRIs don't claim DTAA relief because they don't know how, or they think it's too complicated. It's not. This guide walks you through exactly what DTAA is, how it works, and how to use it in the six major NRI corridors.
What DTAA Actually Does
DTAA doesn't eliminate tax. It eliminates double tax.
Say you're in the US and you receive Rs 1 lakh in dividends from Infosys. India will deduct 20% TDS (tax deducted at source) — that's Rs 20,000 gone before the money hits your account. Then the US wants to tax the same Rs 1 lakh as foreign income when you file your 1040.
Without DTAA, you'd pay Rs 20,000 to India and, say, $300 to the US. Two countries, same income, both taking a cut.
With DTAA, the India-US treaty kicks in. You still pay India's 20%, but the US gives you a foreign tax credit for that Rs 20,000. Your US tax bill drops by the amount you already paid India. You pay tax once, not twice.
That's the core idea.
Two Ways DTAA Gives You Relief
DTAA uses two methods to avoid double taxation: exemption and credit.
Exemption method: One country agrees not to tax the income at all. The income is taxed only in the other country.
Picture this: You're a Singapore tax resident earning rental income from a flat in Bengaluru. The India-Singapore DTAA says rental income is taxed only in India. Singapore exempts it entirely. You pay Indian tax, file your Singapore return, declare the income, and Singapore ignores it for tax purposes.
Credit method: Both countries can tax the income, but one country gives you a credit for the tax you paid to the other.
This is what happens with US dividends. India taxes it. The US taxes it. But the US lets you subtract India's tax from your US tax bill using Form 1116 (Foreign Tax Credit). You pay the higher of the two rates, not the sum of both.
Most DTAAs use the credit method for investment income like dividends, interest, and capital gains. They use the exemption method for things like salaries and pensions, which are usually taxed only where you work or where you're a tax resident.
India-USA DTAA: The Biggest NRI Corridor
The India-US DTAA is the one most NRIs deal with. Over 5 million people of Indian origin live in the US, and most have Indian investments.
Article 10: Dividends
India can tax dividends at a maximum of 25% for non-treaty cases, but the DTAA caps it at 25% for portfolio dividends (you own less than 10% of the company) and 15% for substantial holdings (you own 10% or more).
In practice, India applies 20% TDS on dividends paid to NRIs. If you're a US tax resident, you report this dividend on your 1040, pay US tax at your ordinary income rate (could be 24%, 32%, 37% depending on your bracket), and then claim a foreign tax credit for the 20% India already withheld.
Net result: You pay the higher rate. If your US rate is 32%, you pay 20% to India and 12% to the US after credit. If your US rate is 15% (long-term capital gains, not applicable to dividends but useful to know), you pay 20% to India and zero to the US because you've already paid more than the US would charge.
Article 13: Capital Gains
This is where it gets interesting.
Capital gains from selling Indian stocks are taxed in India. The US also taxes worldwide capital gains for US tax residents. The DTAA doesn't give exemption — it uses the credit method.
Let's say you sell Reliance shares and make Rs 5 lakh in long-term gains (held more than a year). India charges 12.5% LTCG tax under the new regime (FY 2024-25 onward, post-Budget 2024). That's Rs 62,500.
You file your US return. The US treats this as a capital gain, taxable at 15% or 20% depending on your income bracket. Let's say 15%. On Rs 5 lakh (about $5,900 at Rs 85 per dollar), that's $885.
India took Rs 62,500 (about $735). The US wants $885. You claim $735 as a foreign tax credit on Form 1116. You pay an additional $150 to the US. Total tax: $885, not $1,620.
One gotcha: Short-term capital gains (sold within a year) are taxed at 20% in India for NRIs. The US taxes them as ordinary income (could be 24%-37%). The credit method still applies, but your total tax bill will be higher if your US bracket exceeds 20%.
Article 11: Interest
Interest income from Indian savings accounts, fixed deposits, bonds — India can tax it at 30% (standard NRI rate for interest). The DTAA doesn't cap this rate, so India takes the full 30%.
The US taxes this interest as ordinary income. You get a foreign tax credit for the 30% India charged. If your US bracket is 24%, you pay 30% to India and zero to the US. If your bracket is 35%, you pay 30% to India and 5% to the US.
Here's what this means for you: Keep Indian FDs only if the post-tax return beats US Treasury bonds or high-yield savings accounts. At 7% interest and 30% tax, your net return is 4.9%. A US Treasury at 4.5% with 24% tax gives you 3.42%. The FD wins, but not by much after the credit dance.
India-UAE DTAA: No Personal Income Tax Changes Everything
The UAE has no personal income tax. Zero.
So the India-UAE DTAA mostly governs what India can tax, because the UAE won't tax you anyway.
Dividends: India taxes at 20% TDS. The UAE doesn't tax dividends. You pay 20% total. No credit to claim because there's no UAE tax.
Capital gains: India taxes at 12.5% (long-term equity) or 20% (short-term). The UAE doesn't tax capital gains. You pay India's rate, done.
Interest: India taxes at 30%. The UAE doesn't tax interest. You pay 30%.
This is the simplest DTAA scenario. Whatever India charges, you pay, and that's it. No foreign tax credit forms, no reconciliation. The treaty just makes sure the UAE won't suddenly decide to tax you on the same income (it won't anyway, but the treaty locks it in).
One nuance: To claim treaty benefits, you still need a Tax Residency Certificate from the UAE. The UAE Federal Tax Authority issues TRCs even though there's no personal income tax. You need it to prove to India that you're a UAE resident and the treaty applies.
India-UK DTAA
The India-UK DTAA is older (signed 1993, amended multiple times) but widely used.
Article 10: Dividends
India can tax dividends at 15% if you own 10% or more of the voting power, or 25% otherwise. In practice, India charges 20% TDS. The UK taxes dividends under the dividend allowance system — first £500 is tax-free (as of 2024-25), then 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate).
You claim UK foreign tax credit relief for the 20% India charged. If you're a UK higher-rate taxpayer (33.75% on dividends), you pay 20% to India and 13.75% to the UK. Total: 33.75%.
Article 13: Capital Gains
Capital gains from Indian shares are taxed in India. The UK also taxes them. You get credit for India's tax.
India charges 12.5% on long-term equity gains. The UK charges 10% (basic rate) or 20% (higher/additional rate) on gains above the £3,000 annual exempt amount (2024-25).
If you're a UK basic-rate taxpayer, you pay 12.5% to India and zero to the UK (you've already paid more). If you're a higher-rate taxpayer, you pay 12.5% to India and 7.5% to the UK. Total: 20%.
Interest
India charges 30% TDS on NRI interest income. The UK taxes interest as savings income — 20%, 40%, or 45% depending on your band, with a £1,000 personal savings allowance (basic rate) or £500 (higher rate).
You get credit for the 30% India took. If you're a UK higher-rate taxpayer (40%), you pay 30% to India and 10% to the UK after credit.
So what does this mean for you? If you're in the UK and earning interest from Indian FDs, the total tax hit is the higher of the two rates — usually 30% if you're a basic-rate taxpayer, 40% if higher-rate. The FD needs to pay north of 10% gross to beat UK savings accounts after tax. That's rare.
India-Canada DTAA
The India-Canada treaty is similar in structure to the US treaty.
Dividends: India can tax at 15% (if you own 10%+ voting shares) or 25% otherwise. India charges 20% TDS. Canada taxes dividends as ordinary income (federal rates: 15%-33%, plus provincial tax). You claim a foreign tax credit on your Canadian return for the 20% India withheld.
Capital gains: India taxes long-term equity gains at 12.5%. Canada taxes 50% of capital gains as income at your marginal rate (so effective rate: 7.5%-26.5% federally, higher with provincial tax).
Let's say you sell Rs 10 lakh of Tata Motors shares, held 18 months. India takes 12.5% — that's Rs 1.25 lakh. Canada includes 50% of the gain (Rs 5 lakh, about CAD 7,400 at Rs 68 per CAD) in your income. If your marginal rate is 40% (combined federal + Ontario), you'd owe CAD 2,960 on the Rs 5 lakh inclusion. That's about Rs 2 lakh total Canadian tax on the Rs 10 lakh gain, or 20%.
You already paid Rs 1.25 lakh to India. Canada gives you a credit for that Rs 1.25 lakh. You pay an additional Rs 75,000 to Canada. Total tax: 20%, not 32.5%.
Interest: India charges 30%. Canada taxes interest as ordinary income (marginal rates 15%-53% combined federal and provincial). You get credit for the 30% India took. If your combined marginal rate is 45%, you pay 30% to India and 15% to Canada. Total: 45%.
Here's what this means for you: If you're in Ontario and in the top bracket, Indian interest income is taxed at your marginal rate (around 53% combined). The 30% India takes is a credit, so you pay 23% more to Canada. Not attractive unless the Indian FD rate is well above Canadian GIC rates.
India-Australia DTAA
The India-Australia treaty uses similar principles.
Dividends: India can tax at 15%. India applies 20% TDS. Australia taxes dividends as ordinary income (rates: 0%-45% plus 2% Medicare Levy). You claim a foreign tax credit for the 20% India took.
If you're in the 37% bracket in Australia, you pay 20% to India and 17% to Australia (after credit). Total: 37%.
Capital gains: India taxes long-term equity gains at 12.5%. Australia taxes 50% of capital gains as income (effective top rate: 24% including Medicare Levy).
You sell Rs 8 lakh of HDFC Bank shares. India takes 12.5% — Rs 1 lakh. Australia includes 50% of the gain (Rs 4 lakh, about AUD 7,000 at Rs 57 per AUD) in your income. At 47% marginal rate (45% + 2% levy), you owe AUD 3,290 on the inclusion, or about Rs 1.88 lakh total Australian tax on the Rs 8 lakh gain (23.5%).
India took Rs 1 lakh. Australia gives you credit for that. You pay Rs 88,000 more to Australia. Total: Rs 1.88 lakh, or 23.5%.
Interest: India charges 30%. Australia taxes interest at marginal rates. You get credit for the 30%. If you're in the 37% bracket, you pay 30% to India and 7% to Australia. Total: 37%.
So what does this mean for you? Australian residents with Indian investments pay tax at Australian rates on most income types. India's tax becomes a prepayment. The treaty prevents paying twice, but it doesn't lower your total tax below what Australia would charge.
India-Singapore DTAA
Singapore is a low-tax jurisdiction — top personal income tax rate is 24%, and capital gains are generally not taxed.
Dividends: The treaty allows India to tax dividends at 10% if you own 25%+ of the company's shares, otherwise 15%. India actually charges 20% TDS under domestic law, which exceeds the treaty rate. You can claim a refund for the excess or get a lower TDS certificate.
Singapore doesn't tax foreign dividends under its one-tier corporate tax system. So if you're a Singapore tax resident receiving Indian dividends, you pay 10%-15% to India (treaty rate) and zero to Singapore. Total: 10%-15%.
Capital gains: Singapore doesn't tax capital gains. India taxes them at 12.5% (long-term equity) or 20% (short-term). You pay India's rate, Singapore doesn't tax it, and there's no credit to claim because there's no Singapore tax.
Interest: India can tax at 15% under Article 11 of the treaty for interest from loans and bonds. But on bank interest and FDs, India applies 30% under domestic law, and the treaty doesn't limit it. Singapore doesn't tax foreign interest. You pay 15%-30% to India depending on the source, zero to Singapore.
Here's what this means for you: Singapore residents get the best DTAA deal among major corridors. Low treaty rates on dividends, no Singapore tax on capital gains or interest, so your total tax is just what India charges at treaty rates. If you can get a lower TDS certificate, even better.
Getting a Tax Residency Certificate (TRC)
To claim DTAA benefits, you need to prove you're a tax resident of the other country. That's what a TRC does.
Each country issues TRCs differently.
United States: The IRS doesn't issue a standalone TRC. Instead, you use IRS Form 6166 (Certification of U.S. Tax Residency). You file Form 8802 (Application for U.S. Residency Certification) to request it. Processing takes 4-6 weeks. Cost: $85 per certification. The 6166 is accepted by Indian tax authorities as a TRC.
Apply online at IRS Form 8802 page. You need your Social Security Number, previous year's tax return, and the specific period you need certification for.
United Kingdom: HMRC issues Certificates of Residence. You apply online through your HMRC account or by post using Form United Kingdom/Individual. No fee. Processing: 2-3 weeks if you apply online, 4-6 weeks by post.
Link: HMRC Certificate of Residence. You need your National Insurance number and UTR (Unique Taxpayer Reference).
Canada: CRA issues Certificates of Residence for tax treaty purposes. You submit Form NR73 (Determination of Residency Status) or request directly through your CRA My Account portal. No fee. Processing: 2-4 weeks online, 6-8 weeks by mail.
