On June 7, 2023 the IRS confirmed (via Twitter) that California taxpayers who qualify for the disaster-related October 16 postponements (August 15 for Modoc and Shasta counties) still have until the October 16/August 15 postponement deadline to pay their 2022 tax liabilities.
The IRS stated that taxpayers receiving erroneous CP14 letters do not need to call the IRS or their tax professionals.
The IRS acknowledged that the CP14s are automatically generated when taxpayers have a balance due, but that taxpayers eligible for the disaster postponements do not have any balances currently due. From the IRS’s tweets: “The IRS apologizes to taxpayers and tax professionals for any confusion as we continue to review the situation.”
They also stated that "The IRS reassures California taxpayers that they continue to have an automatic extension until later this year to file and pay their taxes for those covered by disaster declarations in the state."
