About this API

TAN identifies the entity responsible for deducting and depositing tax at source. When a counterparty quotes a TAN on a certificate or contract, the TAN Verification API confirms it exists and returns the registered name, so you can be sure the deductor is who they say they are.

It is a small check that prevents a large class of errors in Form 16, Form 16A and TDS reconciliation, and it rounds out entity verification alongside PAN and GSTIN.

Typical uses

• Contractor and vendor onboarding. Verify the TAN of entities that will deduct tax on your invoices.
• Lease and rental agreements. Confirm the tenant entity's TAN for rent TDS.
• Employer verification. Corroborate a previous employer's existence via the TAN on a Form 16.
• Financial counterparties. Validate deductor details in lending and treasury operations.

Questions

Can this verify a previous employer from a Form 16?

Yes. The TAN printed on a Form 16 resolves to the deductor's registered name, which is a useful corroboration during emver verification.

Is TAN the same as PAN?

No. PAN identifies a taxpayer; TAN identifies an entity that deducts tax at source. Many businesses hold both, and emver lets you verify each with its own API.
