What California Form 3534 Is and when it’s used

California Form 3534, Tax Information Authorization, is a state-level consent form that lets a taxpayer authorize a third party to receive or inspect specified tax information from the Franchise Tax Board (FTB). The form documents the scope of the authorization, the authorized recipient, and effective and expiration dates. It is typically used by taxpayers, tax preparers, legal representatives, and businesses to share account transcripts, notices, or other tax records without filing a formal power of attorney. Completing Form 3534 accurately helps avoid processing delays and clarifies who may access tax details.

W-9 and TIN Requests:

Provide taxpayer identification information upon payer request; no fixed statutory deadline

1099-NEC and 1099-MISC Deadlines:

Recipient copies due Jan 31; IRS filing dates vary by paper/electronic method

I-9 Retention:

Keep I-9 for 3 years after hire or 1 year after termination

FTB Processing:

Processing times vary; allow additional weeks for identity verification

Common mistakes that delay processing

Entering an incorrect or mismatched TIN that prevents the FTB from locating the taxpayer’s account and delays release of records.
Vague scope language such as 'all tax documents' that does not specify years or document types and leads to request denials.
Failure to sign with the appropriate authority when signing for an entity, without attaching proof of corporate authority or power of attorney.
Submitting a scanned copy with illegible signatures or missing pages, which often causes the FTB to request a corrected original.
