TDS on Foreign Vendor Payments: Section, Treaty and Gross-Up Working File

Finin2min Tax Desk·June 2026·9 min readFOREIGN TDSValidated: 17 June 2026

Foreign vendor payments need a combined commercial, tax and documentation review. A clean file explains why tax was deducted, not deducted, deducted at treaty rate, or grossed up.

For broader context, see the Income Tax and Salary Hub.

Detailed analysis

Why this matters
The risk is classification. The same invoice can be treated as business profit, royalty, fee for technical services, reimbursement or software/subscription payment depending on facts. Finance should document the reason, not just copy a TDS rate from last year.

Practical example

Example
An Indian startup pays a US vendor for implementation services. The agreement includes service scope, invoice, TRC request, no-PE declaration if used, taxability memo, withholding calculation and Form 15CA/CB file. If contract says company bears taxes, gross-up working is saved.

Evidence and control checklist

Area	What to check	Evidence to save
Payment classification	Royalty/FTS/business income/reimbursement/service fee.	Agreement extracts and taxability memo.
Treaty support	TRC, Form 10F/beneficial ownership/PE declaration where relevant.	Vendor tax documents and email trail.
Withholding calculation	Rate, gross-up and INR conversion.	Computation sheet and approval.
Compliance forms	Form 15CA/15CB route if applicable.	Filed form PDFs and acknowledgement.
Payment and reporting	Challan, bank remittance and ledger entry.	Challan, SWIFT/debit advice and TDS register.
