2024-08: Filing extension announced for San Diego County

UPDATE: The Franchise Tax Board has confirmed that California will conform to the IRS’s storm-related disaster postponement announcement for San Diego County taxpayers, IR-2024-51. (FTB News Release (February 27, 2024)) The FTB’s announcement noted that the postponement includes passthrough entity elective tax payments due on March 15, 2024.

For any given Emergency Measure or Major Disaster Declaration that triggers IRS tax relief or filing/payment postponement in California, the state will evaluate each filing or payment postponement in response to a declaration or emergency on a case-by-case basis. (R&TC §18572)

Due to severe storms, the IRS announced today that individual and business taxpayers located in San Diego County are granted automatic filing relief until June 17, 2024. (IR-2024-51) The June 17 filing postponement matches similar relief provided to taxpayers in other parts of the country suffering from severe storms, such as those for parts of Connecticut, Maine, Michigan, Rhode Island, and West Virginia.

Today’s announcement only covers San Diego county. Currently, no other counties in California are eligible for the filing postponement.

This postponement means that the June 17, 2024, deadline applies to:

  • Individual income tax returns and payments normally due on April 15, 2024;
  • 2023 contributions to IRAs and health savings accounts for eligible taxpayers;
  • 2024 estimated tax payments normally due on April 15, 2024;
  • Quarterly payroll and excise tax returns normally due on January 31 and April 30, 2024;
  • Calendar-year partnership and S corporation returns normally due on March 15, 2024;
  • Calendar-year corporation and fiduciary returns and payments normally due on April 15, 2024; and
  • Calendar-year tax-exempt organization returns normally due on May 15, 2024.

Also, penalties for failing to make payroll and excise tax deposits due on or after January 21, 2024, and before February 5, 2024, will be abated as long as the deposits were made by February 5, 2024.

Taxpayers in San Diego county who need filing extensions beyond June 17, 2024, must file extensions by the June 17 deadline.
