Update

This endpoint modifies the details of an existing business in the TaxBandits API. Use this when a business's name, address, TIN, contact information, or any other detail needs to be corrected or changed after creation.

Identify the business using either its BusinessId or PayerRef. Multiple businesses can be updated in a single request by passing multiple Objects in the Businesses array.

Changes apply to any in-progress returns associated with the business. Updates will not impact returns that have already been transmitted.

Key Points

TIN Format — The TIN Format (PLAIN, ENCRYPTED, TOKEN) can be changed during an update.
DBA Updates — DBA details can be updated here, or separately using the UpdateDBA endpoint.
Identifiers Unchanged — Updating a business does not change its BusinessId or PayerRef.
