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.

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.

FAQs

Is TDS required on every foreign payment?

No. Taxability depends on nature of payment, domestic law, treaty and facts.

What is gross-up?

When payer bears tax, payment may need to be increased to ensure vendor receives net agreed amount.

Why is TRC important?

Treaty benefit generally needs proper documentation such as tax residency evidence.

Does Form 15CB decide taxability?

It certifies details based on CA review, but finance must maintain underlying evidence.

Should exchange rate be documented?

Yes. INR conversion and challan calculation should be traceable.
