If you discover an error on California Form 592, you must file a corrected form to stay compliant with the Franchise Tax Board (FTB) and avoid penalties. Submitting a timely correction ensures accurate withholding reporting and prevents unnecessary interest charges.
Step 1: How to File a Correction
When correcting Form 592:
-
Isolate only the records that need fixing.
-
Prepare a new Form 592 and clearly mark “Amended” at the top left corner.
-
Enter the corrected withholding and payee details (avoid negative numbers).
-
Attach a separate explanation letter stating the reason for the correction.
-
Keep the original Form 592 for your records.
-
Mail the amended form and explanation letter to:
Franchise Tax Board
PO Box 942867
Sacramento, CA 94267-0001

Step 2: What Happens Next?
-
The FTB reviews the correction and may contact you if further clarification is required.
-
If additional tax is owed, you must pay promptly to avoid penalties and interest.
Stay Compliant with Multi-Form Filing
Handling corrections for Form 592 is just one part of tax compliance. If you also file other returns like 1099-MISC, 1099-NEC, or ACA forms (1095-B/1095-C), errors can compound across multiple filings. Using a professional outsourcing service like our IRS filing outsourcing solutions ensures accuracy, saves time, and reduces the risk of penalties.
