You Are Paying Tax Twice on the Same Income — and You May Not Even Know It
Double taxation happens more often than most taxpayers realise. It happens to Indian residents who earn income abroad. It happens to NRIs earning income in India. It happens to business owners whose company pays tax on profit and who then pay tax again on dividend income received from that same profit.

The good news is that India has a comprehensive legal framework to prevent or eliminate double taxation — through Double Taxation Avoidance Agreements with 90-plus countries, through unilateral relief provisions in the Income Tax Act, and through specific exemptions that protect certain categories of income from being taxed twice.
Understanding these mechanisms is not just a compliance exercise. It is a genuine money-saving exercise. The taxes you avoid through correct application of DTAA provisions and domestic relief sections are taxes you legally do not owe — and claiming them correctly is your right, not a loophole.
Sharda Associates is a CA firm based in Bhopal, Madhya Pradesh, India. Our CA team helps businesses and individuals across India structure their income and investments to legally minimise double taxation exposure — through correct DTAA application, proper filing of Tax Residency Certificates, and accurate documentation for foreign income claims.

What Is Double Taxation
The Direct Definition
Double taxation occurs when the same income is taxed by two different tax authorities — typically two different countries — in the same assessment year. An Indian software engineer working in Germany pays German income tax on their salary. If India also taxes that same salary income as worldwide income of an Indian resident — the engineer has paid tax twice on the same earnings. Double taxation agreements and domestic relief provisions exist specifically to prevent this.
Double taxation has two main forms in practice.
Juridical double taxation — the same person is taxed on the same income in two countries. This is the most common form and is directly addressed by DTAA agreements.
Economic double taxation — two different persons are taxed on the same underlying income. The classic example is corporate dividend — the company pays corporation tax on its profit, and the shareholder then pays income tax on the dividend received from that same profit.
India's Framework for Avoiding Double Taxation
Three Mechanisms That Protect You
India addresses double taxation through three distinct legal mechanisms — Double Taxation Avoidance Agreements signed with foreign countries, unilateral relief under Section 91 of the Income Tax Act for countries without DTAA, and specific domestic exemptions for categories like agricultural income and certain dividend income. Understanding which mechanism applies to your specific situation determines how much relief you can claim.
Mechanism 1 — Double Taxation Avoidance Agreements
India has signed DTAAs with over 90 countries including the United States, United Kingdom, UAE, Singapore, Germany, Australia, Canada, Japan, and most major economies where Indian nationals work or invest.
A DTAA between India and another country does one of three things for each income category — it allocates the right to tax exclusively to one country, it allows both countries to tax but requires the country of residence to give credit for tax paid in the source country, or it limits the tax rate that the source country can charge.
Key DTAA Countries and Key Provisions
The UAE DTAA is particularly relevant for Indian nationals working in the Gulf — since UAE has no income tax, the DTAA effectively means Gulf salary income is taxable only in UAE — and since UAE charges no tax, the net tax on Gulf employment income for a genuine UAE resident is zero.
Mechanism 2 — Unilateral Relief Under Section 91
Section 91 of the Income Tax Act provides relief for residents who earn income from countries with which India does not have a DTAA. The relief equals the lower of Indian tax rate on that income or the foreign tax actually paid. This ensures that even without a formal bilateral agreement, income taxed abroad is not fully taxed again in India.
To claim Section 91 relief — you must be an Indian resident, the income must be from a country without DTAA with India, the income must have been taxed in that foreign country, and you must provide documentary evidence of foreign tax paid.
Mechanism 3 — Domestic Exemptions
Certain income categories are specifically exempted from double taxation within India's domestic tax law.
Agricultural income — exempt from income tax under Section 10(1). A dairy farmer, poultry farmer, or goat farmer pays no income tax on farm income regardless of amount. No DTAA is needed — the domestic exemption provides complete relief.
Dividend income — after the abolition of Dividend Distribution Tax and introduction of dividend taxation in shareholders' hands, Section 80M provides deduction to domestic companies receiving dividends to prevent cascading corporate double taxation.
Tax Residency Certificate — The Document That Makes DTAA Work
Why TRC Is Non-Negotiable for DTAA Claims
A Tax Residency Certificate — TRC — issued by the tax authority of your country of residence is the foundational document required to claim DTAA benefits in India. Without a valid TRC, the Indian Income Tax Department will not give DTAA relief on Indian-source income. For NRIs and foreign nationals earning income in India, obtaining and submitting the correct TRC is the first step in legitimate double taxation avoidance.
The TRC must be obtained from the official tax authority — not from a private consultant or online service. For an Indian earning income in the UAE — the Federal Tax Authority of UAE issues the TRC. For an Indian in the UK — HMRC issues it. For an Indian in the US — the IRS issues it.
Form 10F — Supporting Declaration
Along with the TRC, Indian tax law requires Form 10F — a self-declaration providing specific details about the taxpayer's residency status, tax identification number in the foreign country, nationality, and period of residency.
Form 10F must be filed online on the Income Tax portal. As of 2023 and continuing through 2026, NRIs without a PAN can also file Form 10F electronically after registering on the portal with their passport details.

Double Taxation Situations Most Commonly Faced by Indian Taxpayers
Situation 1 — NRI Working Abroad With Indian Income
An NRI who has property in India earning rental income, or fixed deposits earning interest, or capital gains from selling Indian property — faces potential double taxation if their country of residence also taxes worldwide income.
The DTAA between India and the NRI's country of residence determines the correct treatment. Most DTAAs allow India to tax Indian-source income but require the residence country to give credit for Indian tax paid — eliminating double taxation.
Situation 2 — Indian Resident With Foreign Employment Income
An Indian tax resident — present in India for 182 days or more in a financial year — is taxed on worldwide income. If they also earned employment income abroad during the year — perhaps from a foreign assignment or earlier period of foreign employment — both India and the foreign country may have taxed that income.
The DTAA provides relief through the foreign tax credit mechanism. The foreign tax paid is credited against Indian tax liability on the same income — ensuring total tax does not exceed the higher of the two countries' tax rates.
Situation 3 — Business With Foreign Operations
An Indian company operating through a branch or subsidiary in a foreign country pays corporate tax in that country on foreign profits. If dividends from the foreign subsidiary are then repatriated to India — the Indian parent may face tax on those dividends despite the profit already being taxed abroad.
Section 90 and 90A and relevant DTAA provisions address this through participation exemption or foreign tax credit mechanisms. Structuring these arrangements correctly requires CA-level expertise — mistakes cost significant tax.
Situation 4 — Capital Gains on Foreign Assets
An Indian resident who sells shares in a foreign company or property held abroad generates capital gains taxable in India as worldwide income. The foreign country may also tax the same gains as source-country income.
The applicable DTAA determines whether capital gains are taxable only in India, only in the foreign country, or in both with credit available. Singapore and Mauritius DTAAs have historically been important in this context for investment structures — though treaty shopping provisions have been progressively tightened.
How to Claim Double Taxation Relief — Step by Step
For DTAA Relief on Foreign Income
Step 1 — Determine your residential status for the relevant financial year. Resident and Ordinarily Resident, Resident but Not Ordinarily Resident, or Non-Resident — each category has different worldwide income taxation rules.
Step 2 — Identify the applicable DTAA between India and the country where the income was earned or where you were resident.
Step 3 — Obtain a Tax Residency Certificate from the tax authority of your country of residence.
Step 4 — Complete Form 10F on the Income Tax portal with your residency and tax identification details.
Step 5 — In your Indian ITR — report the foreign income in the Foreign Income schedule. Compute the foreign tax credit in Schedule FSI and Schedule TR.
Step 6 — Claim the lower of Indian tax rate on the income or the foreign tax paid as credit against your Indian tax liability.
Step 7 — Attach documentary evidence — TRC, Form 10F, foreign tax payment receipts — with your ITR or have them ready for verification if your case is selected for scrutiny.
For Section 91 Relief
Same process but without a formal DTAA. Section 91 requires proof that the income was taxed in the foreign country — typically a foreign tax assessment or payment receipt — and that the country does not have a DTAA with India.
Common Mistakes That Lead to Unnecessary Double Taxation
Mistake 1 — Not Filing TRC Before Receiving Indian Income
Many NRIs who invest in Indian fixed deposits, rent out Indian property, or receive Indian dividends do not obtain or submit a TRC to the payer. The payer — bank, tenant, company — then deducts TDS at the higher non-treaty rate. Recovering the excess TDS through ITR filing is possible but time-consuming. Submitting the TRC before income is paid eliminates this problem.
Mistake 2 — Incorrect Residential Status Determination
The residential status determination — which depends on precise day-count calculations of India presence — determines whether you are taxed on worldwide income or only Indian income. An error in residential status determination can result in either underpayment — resulting in notices and interest — or overpayment of tax that is not recovered.
Mistake 3 — Not Claiming Foreign Tax Credit in ITR
Many taxpayers who paid foreign tax on income also taxable in India simply pay the full Indian tax without claiming the foreign tax credit they are entitled to. This is a straightforward financial loss. The foreign tax credit is a right — Schedule FSI and Schedule TR in the Indian ITR are specifically designed to capture and apply it.
Mistake 4 — Using Treaty Benefits Without Proper Documentation
Claiming DTAA benefits without maintaining proper documentation — TRC, Form 10F, foreign tax payment evidence — creates scrutiny risk. The Income Tax Department can disallow DTAA benefits and demand tax at domestic rates if documentation is absent or inadequate.
