Sacramento – The Franchise Tax Board announced it will soon begin mailing Notices of Tax Return Change – Revised Balance (FTB 5818B) as a reminder and courtesy to taxpayers. The notices will be mailed starting the first week in July.

This notice is sent when FTB corrects one or more items on a tax return. Taxpayers have the option to pay any balance due now or pay by their respective county's established disaster extension due date, which in most cases is October 161 this year.

"The California winter storm disaster declarations are a challenging and fluid situation for us all," said State Controller and FTB Chair Malia M. Cohen. "We appreciate the tax community's patience and partnership as we navigate through this unique filing season together."

The disaster declarations extended the due date for multiple personal and business entity tax payments. To ensure payments are processed timely and accurately, please do not combine payments for different tax years.

FTB recommends taxpayers submit separate payments vs. one lump-sum payment for the following:

  • Personal income tax payments (2022 Tax Year).
  • Quarterly estimated tax payment (2022 Tax Year).
  • Quarterly estimated tax payments (2023 Tax Year).
  • Business entity tax payments (2022 Tax Year).
  • Pass-through entity (PTE) elective tax payments (2022 Tax Year).
  • Pass-through entity (PTE) elective tax payments (2023 Tax Year).
