Documents required for Form 13 (lower TDS certificate) application
At minimum, you'll need your PAN, proof of NRI status (passport/OCI), the relevant agreement (sale deed, rental agreement, or interest certificate), and prior ITRs if any were filed in India. Property sales additionally require the original purchase deed and payment proof to establish cost of acquisition.
Why documentation matters more here than in most filings
A Form 13 application is essentially asking the Assessing Officer to trust a computation of your actual tax liability instead of applying a safe default rate — so the strength of your documentation directly affects both whether it's approved and how long it takes. Missing or inconsistent documents are one of the most common causes of delay, covered in more detail in our guide to why applications get rejected or delayed.
Core documents, every application
PAN card (mandatory — the certificate is issued against it), proof of NRI status such as your passport and OCI card or valid visa, and prior years' Indian ITRs if you've filed any before. These establish who you are, confirm your non-resident status for the relevant period, and give the Assessing Officer a tax history to cross-check against.

Ask our CA →For a property sale
You'll additionally need the original purchase deed and proof of what you paid at the time (bank transfer records, the earlier sale deed), plus the current sale agreement. These together let your CA compute the cost of acquisition and the resulting capital gain — the whole basis of the property sale certificate. Any improvement costs you can document (renovation invoices, for example) may also be relevant.
For rental income or interest income
For rental income, the rental agreement and, ideally, a record of rent received so far in the year. For NRO interest, the interest certificate from your bank and your NRO account statements. In both cases, your NRO/NRE bank statements for the relevant period help substantiate the income being declared.
What if I don't have all my prior years' ITRs?
It isn't necessarily a dealbreaker — many first-time NRI applicants haven't filed an Indian ITR before, especially if this is their first taxable transaction here. It does mean your CA will lean more heavily on the current transaction's documentation to support the computation, since there's less tax history to point to.
