Why is proof of authorization required?

If your payer is required to provide proof of authorization, it means you must provide supporting documentation proving your authorization to file tax forms on behalf of this payer. This ensures compliance with IRS and SSA requirements.

How to resolve it:

To continue filing, you’ll need to:

Upload supporting documentation: If the details are correct and you’re authorized to file for this payer, submit proof to confirm your authorization and the accuracy of the amounts reported.

Acceptable documents

CP595 notice – A letter from the IRS indicating the business’s tax status

Proof of tax deposits – Documentation confirming that tax withholdings have been deposited with the IRS or applicable state agency

Providing the appropriate documentation helps confirm your authority to file and allows the return to move forward without delays.
