Taxpayer Brief
A Tax Residency Certificate is a document issued by the foreign country's tax authority confirming that the holder is a tax resident of that country for the period stated. Sub-section (4) of section 90 of the Income-tax Act, 1961, read with Rule 21AB of the Income-tax Rules, 1962, makes the Tax Residency Certificate mandatory for an Indian assessee -- including a Non-Resident Indian -- who wants to claim the lower withholding rate under a Double Taxation Avoidance Agreement on Indian-source income. Without the Tax Residency Certificate plus Form 10F, the Indian payer is bound by the higher domestic Tax Deducted at Source rate. This article walks through the process for the three most common Non-Resident Indian residence countries -- United States, United Kingdom, and Canada -- with timelines, costs, and renewal cycles.
1. The Tax Residency Certificate Requirements -- Rule 21AB
Rule 21AB prescribes that a Tax Residency Certificate from a foreign country must contain at least the following information.
Required Detail | Source |
|---|---|
Name of the assessee | Foreign tax authority |
Status (individual / company / firm) of the assessee | Foreign tax authority |
Nationality (where applicable) | Foreign tax authority |
Country / specified territory of incorporation or registration / residence | Foreign tax authority |
Assessee's tax identification number in the country | Foreign tax authority |
Residential status for the period of validity | Foreign tax authority |
Period for which the certificate is applicable | Foreign tax authority |
Address of the assessee in the foreign country | Foreign tax authority |
2. United States -- Form 6166
The United States Internal Revenue Service issues the Tax Residency Certificate as Form 6166. The application is filed on Form 8802 (Application for United States Residency Certification).
Step | Action | Time / Cost |
|---|---|---|
1 | Complete Form 8802 -- listing applicable tax-treaty country (India), purpose, type of income, year(s) for which certificate is required | 1 to 2 hours |
2 | Pay user fee -- $85 per application for individual applicant covering up to 20 certificates of the same type for a single tax year (per the Internal Revenue Service fee schedule current as of 2026) | $85 |
3 | Mail Form 8802 with payment and supporting documents (passport copy, certified Internal Revenue Service tax returns) to the Internal Revenue Service Form 8802 mail address (Philadelphia, Pennsylvania) | Day 0 |
4 | Internal Revenue Service processes -- standard processing 6 to 8 weeks; expedited not available | Day 1 to Day 60 |
5 | Form 6166 issued -- contains the Internal Revenue Service certification stamp, Letterhead, period of validity (usually full calendar year) | Receive by post |
6 | Translate / apostille if specifically required by the Indian payer (rarely needed -- Form 6166 is widely accepted as-is) | If required |
7 | Submit Form 6166 to the Indian payer along with Form 10F | Day 61 onwards |
Internal Revenue Service tax-return prerequisite Form 6166 will be issued only if the applicant has filed at least one current-year Internal Revenue Service tax return (Form 1040 / 1040-NR / 1120 etc.). For a first-year United States resident, this means waiting until the 15 April or extended October return is filed before the Tax Residency Certificate can issue. Plan India-source income / withholding accordingly. |
3. United Kingdom -- HMRC Certificate of Residence
Her Majesty's Revenue and Customs (HMRC, recently rebranded as His Majesty's Revenue and Customs from 2022) issues a Certificate of Residence on application by the United Kingdom-resident assessee.

6. The Form 10F Companion
Form 10F is a self-declaration filed by the Non-Resident Indian on the Indian e-filing portal supplementing the Tax Residency Certificate. It captures the same Rule 21AB details (name, status, nationality, country, tax identification number, period, address) plus a declaration of Indian Permanent Account Number. From October 2023 onwards, Form 10F filing requires a Permanent Account Number. The form is signed by the Non-Resident Indian and uploaded to the e-filing portal; the system-generated acknowledgement is shared with the Indian payer. Without Form 10F, the lower Double Taxation Avoidance Agreement rate is not applied at source.

(ii) Treatment of the e-Form 10F architecture -- the Income Tax Department portal mandates e-filing of Form 10F. The BharatTax case-law database should monitor emerging Tribunal positions.
