A DTAA (Double Taxation Avoidance Agreement) is a treaty between India and another country that decides which country may tax a given type of income, and how much. For service exporters, it matters in two moments: when a foreign client wants to withhold tax from your payment, and when you file your Indian return and want credit for anything that was withheld. The paperwork that gets you treaty treatment is usually a tax residency certificate from India, plus whatever form the client's country uses.
Key takeaways
- India taxes its residents on worldwide income, so your export earnings are taxable here regardless of where the client is.
- A foreign client may deduct tax at source under its own law. A DTAA can reduce or remove that deduction if you prove you are an Indian tax resident.
- The usual proof is a tax residency certificate (TRC) issued by the Indian income-tax department. US clients typically ask for Form W-8BEN-E (entities) or W-8BEN (individuals) instead or as well.
- If tax is still withheld abroad, you may be able to claim foreign tax credit in India. Form 67 is part of that claim.
- DTAA and income tax sit entirely outside the EDF. Filing the EDF does not change your tax position.
Why double tax happens at all
Picture Saffron Code Pvt Ltd in Bengaluru, invoicing a client in another country USD 10,000 for software development. India taxes Saffron Code on that income because it is an Indian resident company. The client's country may also claim a right to tax payments made to foreigners for services, and enforce it by making the client withhold a percentage before paying.
Without a treaty, Saffron Code could pay tax twice on the same USD 10,000. A DTAA sorts out who gets to tax what. For many ordinary services delivered remotely from India, treaties often leave the taxing right mainly with India, especially where the Indian business has no fixed base or permanent establishment abroad. But treaties differ country to country and article by article, and some treat "fees for technical services" separately. You cannot assume the outcome; you or your CA have to read the specific treaty.
The documents clients ask for
| Document | Who issues it | What it does | Who usually asks |
|---|---|---|---|
| Tax residency certificate (TRC) | Indian income-tax department, on application | Proves you are an Indian tax resident for treaty purposes | Clients in many treaty countries |
| Form W-8BEN-E | You fill it (entities) | Certifies foreign status to a US payer and can claim treaty benefits | US clients and US platforms |
| Form W-8BEN | You fill it (individuals) | Same as above, for individuals | US clients of freelancers |
| Client-country forms | Varies | Some countries have their own exemption or reduced-rate forms | Depends on the country |
| PAN and incorporation documents | You | Supporting identity | Often requested with the above |
Tax residency certificate
The TRC is applied for through the income-tax portal, generally using Form 10FA, and the certificate is issued in Form 10FB. Apply early in the financial year if you have clients who insist on it, since a client will usually want a TRC covering the period of payment. Our article on TRC, Form 10FA and 10FB covers when it is worth the effort.
W-8BEN-E for US clients
US payers commonly ask non-US vendors for a W-8 form. An Indian company fills W-8BEN-E; an individual fills W-8BEN. Filled correctly, it tells the payer you are not a US person and may claim treaty benefits. Many Indian businesses supplying services performed entirely in India find that US clients do not withhold once the form is in place, but the outcome depends on the facts and the form's answers. The W-8BEN-E glossary entry explains the basics.
When tax is withheld anyway
Sometimes a client withholds regardless: their policy is conservative, a form arrived late, or the treaty genuinely allows the other country to tax. You are then holding a net payment and a withholding certificate.
Take Saffron Code again. The invoice is USD 10,000, the client withholds 10% and remits USD 9,000. Three separate things now happen:
- For FEMA and the EDF, the invoice value was USD 10,000. You realised USD 9,000 in cash and USD 1,000 went to the foreign tax authority on your behalf. Tell your bank why the receipt is short and keep the withholding certificate. Ask your bank how it wants to see this when closing the export entry.
- For income tax in India, you report the full USD 10,000 equivalent as income, not the USD 9,000.
- For foreign tax credit, you may be able to claim credit for the tax withheld, subject to the treaty and Indian rules. Form 67 must be filed as part of that claim. Your CA will handle the computation; see our article on foreign tax credit and Form 67.
| Item | Amount |
|---|---|
| Invoice value | USD 10,000 |
| Withheld abroad (illustrative 10%) | USD 1,000 |
| Received in India | USD 9,000 |
| Rupee value received at ₹84 | ₹7,56,000 |
| Income to report in India | Full ₹8,40,000 equivalent |
| Credit to explore | ₹84,000 equivalent, via Form 67 |
Figures are illustrative only. Actual withholding rates, if any, depend on the client's country, the treaty and the nature of the service.
A practical routine
- At onboarding, ask every new foreign client what tax forms they need from you. Send them before the first invoice.
- Each April, apply for a fresh TRC if any client requires one.
- Keep a register of clients who withhold, the rate, and the certificates received.
- Chase withholding certificates promptly. Without one, claiming credit becomes harder.
- Tell your bank when a payment is short because of withholding, so it is not treated as a short realisation without explanation.
What DTAA does not affect
DTAA is about income tax. It has nothing to do with GST, which treats your export of services as a zero-rated supply if the Section 2(6) IGST conditions are met. It also has nothing to do with the EDF, which is a FEMA declaration to your AD bank. The EDF does not change your GST or income-tax obligations.

Frequently asked questions
What is a DTAA in simple terms?
It is a treaty between two countries that decides which country may tax a particular type of income and limits double taxation. For Indian service exporters, it often decides whether a foreign client may withhold tax and whether you can claim credit for tax paid abroad.
Do I need a tax residency certificate for every client?
Only for clients whose countries or internal policies require it to apply treaty rates. Many clients ask for nothing, and US clients usually ask for a W-8 form instead. Ask at onboarding and apply for a TRC if needed.
Should an Indian company fill W-8BEN or W-8BEN-E?
An Indian company or LLP fills W-8BEN-E, which is for entities. W-8BEN is for individuals. Get your CA to review the treaty article you claim before signing.
If tax is withheld abroad, is my EDF value wrong?
No. The EDF shows the invoice value. The shortfall is explained by the withholding certificate. Inform your bank and keep the certificate with the FIRA so the export entry can be reconciled.
Can I claim credit for tax deducted by a foreign client?
Often, yes, subject to the treaty and Indian income-tax rules, and Form 67 is part of the process. The credit is computed by your CA when you file your return.
Bottom line
Collect the right residency documents before the first invoice, report the gross income, and claim credit for anything withheld. Keep your EDF and invoices consistent with the free EDF form generator, so the FEMA side never contradicts the tax side.
