How to update the TIN on a Zerodha account
This guide explains how to update your Tax Identification Number (TIN) on a Zerodha account through the FATCA declaration, why Zerodha emails you to do it, and who actually needs to provide one. A TIN is the number a foreign tax authority assigns to a taxpayer, the overseas equivalent of an Indian PAN, and Zerodha is required to collect a valid one from any client who is a tax resident of a country other than India.
You are reading this most likely because an email from Zerodha asked you to update or correct your TIN. That email is not a scam and not optional. The Income Tax Department directs brokers to collect a valid TIN from clients who submitted an incorrect or invalid one, so that the broker can meet its reporting obligations under the FATCA and CRS framework. The fix is a short online declaration, free, that you can complete yourself.
This guide is for NRIs, OCI cardholders and foreign nationals who hold a Zerodha account and have foreign tax residency. A resident Indian with no tax residency outside India does not need a TIN and simply answers No to the foreign-tax-residence question. If you have actually become an NRI, the TIN update is one part of a larger change; pair it with How to update PAN and residential status when you become an NRI .

Step-by-step procedure
The numbered box at the top of this guide gives the sequence. The detail below expands each step, including what to do when your country issues no TIN.
1. Confirm whether you owe a TIN at all
A TIN is required only if you are a tax resident of a country other than India. Tax residency is not the same as citizenship: an Indian citizen working abroad long enough to become a tax resident there owes that country’s TIN, while an OCI cardholder who is tax-resident only in India does not. If India is your sole tax residence, you will answer No to the foreign-tax-residence question in step 3 and will not be asked for a TIN. If you are tax-resident anywhere else, even in addition to India, you must declare it and provide that country’s TIN.
2. Open the FATCA declaration
Log in to your account at account.zerodha.com/account and open the FATCA section. You can also go straight to the dedicated form at signup.zerodha.com/rekyc/fatca. This is the same FATCA declaration captured during account opening; updating the TIN means re-submitting it with the correct value. The form first collects your income details, occupation and political-exposure status, so have those ready.
3. Declare foreign tax residence
When the form asks “Do you have tax residence in any other country than India?”, select “Yes, I do” if you are a foreign tax resident. The form then expands to capture your city and country of birth and your other country or countries of tax residence. Select the correct country of tax residence from the list.
4. Enter the TIN in the correct format
Enter the TIN issued by your country of tax residence. Each country’s TIN has its own format, so accuracy matters; an incorrectly formatted number is exactly the “invalid TIN” the Income Tax Department flagged in the first place. If you are unsure what your country’s TIN looks like, the OECD publishes TIN formats by country on its automatic exchange of information pages; confirm the format there before entering it.
5. Handle the no-TIN case
Some countries do not issue a Tax Identification Number, and seafarers, who can lack a settled tax residence, sit in a similar position. If your country of residence does not issue a TIN, or you are a seafarer, select “No” to the question about tax residence in another country, then submit the declaration. Do not invent or guess a number where none is issued; the No path is the correct treatment, and the framework provides for the reason-for-no-TIN case.
6. Submit and confirm
Click Continue or Submit to file the declaration. The corrected TIN flows into Zerodha’s FATCA and CRS records and onward to the reporting that the broker files with the Income Tax Department. Keep a note of the date you submitted, and if the broker had set a deadline (the CVLKRA FATCA declaration deadline was 31 October 2024), confirm you have met it.
Why the email asks for a TIN: the FATCA and CRS framework
The request traces to two international tax-transparency regimes that India has implemented domestically. FATCA is the United States’ Foreign Account Tax Compliance Act, given effect in India through the India-US Inter-Governmental Agreement. The CRS is the OECD’s Common Reporting Standard for automatic exchange of financial-account information among many countries. Both require financial institutions to identify account holders who are tax-resident abroad and report their accounts to the home tax authority for onward exchange.
India brought these obligations into law through Section 285BA of the Income Tax Act, 1961 and Rules 114F to 114H of the Income-tax Rules, 1962, inserted by Notification No. 62 of 2015 dated 7 August 2015, together with reporting Form 61B. Rule 114F defines a reporting financial institution, which includes a broker holding financial assets for customers. Rule 114G sets the reporting requirement, the filing of Form 61B with the Director of Income-tax (Intelligence and Criminal Investigation). Rule 114H prescribes the due-diligence procedures, including obtaining a self-certification from each account holder that captures tax residency and the TIN. Your FATCA declaration on Zerodha is that self-certification. The TIN is the field that lets the foreign authority match the report to you, which is why a valid one is mandatory and an invalid one triggers the follow-up email.
How the TIN update relates to your residential status
Updating the TIN is a declaration about tax residency. It is not, by itself, a change of your account’s residential status. If you remain a resident Indian for KYC purposes but happen to be tax-resident abroad as well, the TIN declaration alone is the correct and complete step.
If you have genuinely become an NRI, the TIN is only one piece. You must also update your residential status to non-resident on the Income Tax Department records and convert your resident account to an NRI-NRO account through a full re-KYC . The two are connected in practice, the FATCA declaration with TIN is part of the NRI conversion paperwork, but they are distinct actions with different consequences. NRI clients whose residential status was not updated on the Income Tax Department records by 9 February 2024 were blocked from trading on the NSE and BSE, so an NRI should not stop at the TIN. Follow How to update PAN and residential status when you become an NRI for the full conversion.
