Form 10F is a self-declaration that a non-resident files with the Indian Income Tax Department to claim the lower withholding rate promised by a tax treaty between India and their home country. It works alongside a Tax Residency Certificate from your home tax authority, filling in whatever details that certificate leaves out. Without it, the Indian company or bank paying you will withhold tax at India’s full domestic rate, which for common cross-border payments can run as high as 20% to 30%.
Who Has to File It
You need Form 10F if you are a non-resident claiming treaty relief under Section 90 or Section 90A of the Income Tax Act. Section 90 covers agreements the Indian central government has signed with foreign countries to prevent the same income being taxed twice; Section 90A covers agreements between specified associations.1Income Tax Department. Double Taxation Relief In plain terms, you qualify if you are a tax resident of a country that has a standing treaty with India and you receive taxable income from an Indian source.
The Tax Residency Certificate issued by your home country’s tax authority is the primary proof of treaty eligibility, but it rarely contains everything India’s rules ask for. Form 10F exists to close that gap. Even if your certificate happens to cover every required field, most non-residents still file the form to avoid processing friction with the Indian payer.
What Form 10F Asks For
Rule 21AB sets out six pieces of information the form must carry:
- Your status — individual, company, firm, or other entity type.
- Your Indian Permanent Account Number (PAN) or Aadhaar, if one has been allotted to you.
- Your nationality (for individuals) or country of incorporation or registration (for entities).
- Your Tax Identification Number in your home country, or whatever unique identification number your home government uses if no TIN exists.
- The residency period your Tax Residency Certificate covers. These dates must match the certificate exactly.
- Your address outside India during the period covered by the certificate.
If your Tax Residency Certificate already contains one of these items, you can enter “N/A” for that field. Anything not on the certificate must be filled in on the form; leaving fields blank invites the Indian payer to default to the higher domestic withholding rate.
Get Your Tax Residency Certificate First
Form 10F cannot stand on its own. You need a valid Tax Residency Certificate from your home tax authority confirming your resident status for the relevant period, and that certificate has to line up with India’s assessment year (April through March). Mismatched dates are a common reason treaty claims are denied.1Income Tax Department. Double Taxation Relief
If You Are a US Tax Resident
You get your certificate by filing IRS Form 8802. The IRS then issues Form 6166, a letter on Department of Treasury letterhead certifying your US residency for the year in question.2Internal Revenue Service.

Form 8802, Application for United States Residency Certification – Additional Certification Requests The IRS generally issues Form 6166 only after confirming you filed an appropriate return for the certification year.
If You Are Resident Elsewhere
Every treaty country has its own process. Contact your home tax authority well in advance and confirm the certificate will cover the specific Indian assessment year for which the income is earned.
The PAN Problem and Paper Filing
Electronic filing of Form 10F has been mandatory since October 1, 2022, and the e-filing portal requires a login tied to an Indian PAN. Many non-residents do not have a PAN and are not legally required to obtain one, which created an immediate practical problem.
The Directorate of Income Tax (Systems) responded with a partial relaxation: non-residents who do not have a PAN and are not required to have one may submit Form 10F manually on paper and hand it directly to the Indian entity withholding tax.5Income Tax Department. Partial Relaxation With Respect to Electronic Submission of Form 10F If that is your situation, complete the physical form and provide it to the payer along with your Tax Residency Certificate.
PAN still matters for another reason. Under Section 206AA, if you do not furnish a PAN, the Indian payer must withhold at 20% or the rate in force, whichever is higher — potentially above the treaty rate. Rule 37BC carves out an exception: if you give the Indian payer your name, contact details, foreign address, Tax Residency Certificate, and home-country Tax Identification Number, the Section 206AA higher rate does not apply even without a PAN.6Income Tax Department. Non-Resident – Benefits Allowable For non-residents with regular Indian income, obtaining a PAN is often still the cleaner path.
Filing on the E-Filing Portal
Keep your Tax Residency Certificate open before you start. You will reference its dates, the issuing authority, and its address as you move through the screens.
- Log in at incometax.gov.in using your PAN and password.
- From the dashboard, select the “e-File” tab, then “Income Tax Forms.”
- Click “File Income Tax Forms,” open the tab for “Person not dependent on any source of Income,” and find Form 10F under “Double Taxation Relief.” Click “File Now.”
- Choose the assessment year. India’s assessment year runs April through March, so income earned between April 2025 and March 2026 falls under Assessment Year 2026–27.
- Select whether your claim is under Section 90 or Section 90A.
- Complete the information fields. Status and PAN are typically pre-filled; enter nationality or country of incorporation, your Tax Identification Number, the residency period matching your certificate, and your foreign address.
- Enter the address of the foreign authority that issued your Tax Residency Certificate.
- Upload the certificate as a PDF. Each attachment must be under 5 MB, and the combined attachments cannot exceed 50 MB.
Authenticating the Submission
You must authenticate before the form goes through, and the method depends on who you are. Companies and non-residents whose accounts require an audit under Indian law have to use a Digital Signature Certificate. The portal accepts class 2 or class 3 certificates from an Indian Certifying Authority, and the certificate must be active.7Income Tax Department. DSC Tutorial Register the DSC USB token on the portal before you start filing.
Individuals not subject to audit can authenticate with an Electronic Verification Code instead. The portal sends a one-time password to your registered mobile number or email.
Once authentication finishes and you submit, the portal generates a filing acknowledgment with a unique transaction number. Save it. That receipt is your proof of compliance and the document you share with the Indian payer so they can apply the lower treaty rate.
What It Costs You to Skip Form 10F
The Indian payer will withhold at the full domestic rate. For a US resident receiving royalties from an Indian company, the domestic rate under Section 115A is 20%, while the Indo-US treaty rate falls in the 10% to 15% range depending on the category.8Embassy of India, Washington D.C. TDS (Withholding Tax) Rates Under Indo-US DTAA The gap on interest income runs similarly, with domestic rates at 20% versus treaty rates of 10% to 15%.9Income Tax Department. Taxation of Non-Resident
You can recover the excess by filing an Indian income tax return and claiming a refund, but that route can take months or years, usually requires obtaining a PAN, and often means hiring a tax professional in India. Getting Form 10F to the payer before they cut the check is far cheaper.
If the Indian payer fails to apply the correct treaty rate after you have provided proper documentation, the liability shifts to them. In practice most Indian payers will withhold at the higher rate rather than risk their own exposure, which means the paperwork burden sits with you.
Keep the Paperwork
Store the filed Form 10F, the acknowledgment receipt, and the Tax Residency Certificate together. The Income Tax Department can reassess prior years, and the limitation window varies with the amount of income and the circumstances involved. Indian tax guidance generally suggests keeping business-related records for a minimum of eight years; individual non-residents should hold onto these documents for at least six years from the end of the relevant assessment year.
If the department requests these records during a reassessment and you cannot produce them, you lose the basis for your treaty claim. The higher domestic rate can then be applied retroactively, with interest running from the original due date. Keeping the original Tax Residency Certificate alongside digital copies is worth the small inconvenience.
