Yes, I agree.Tbh the IRS website does not specifically say no interest, although it does say no penalties. But, if the due date is Oct. 16, that's the due date, payments are not late so there should be no interest. Hoping they address this later.  Notice they anticipate erroneous notices going out. At least they're honest about that.

WASHINGTON — Victims of severe winter storms, flooding, and mudslides in California beginning Jan. 8, 2023, now have until Oct. 16, 2023, to file various individual and business tax returns and make tax payments, the Internal Revenue Service announced today.

Following the disaster declaration issued by the Federal Emergency Management Agency, individuals and households affected by severe winter storms, flooding, and mudslides that reside or have a business in Alameda, Colusa, Contra Costa, El Dorado, Fresno, Glenn, Humboldt, Kings, Lake, Los Angeles, Madera, Marin, Mariposa, Mendocino, Merced, Mono, Monterey, Napa, Orange, Placer, Riverside, Sacramento, San Benito, San Bernardino, San Diego, San Francisco, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Solano, Sonoma, Stanislaus, Sutter, Tehama, Tulare, Ventura, Yolo, and Yuba counties qualify for tax relief.

The declaration permits the IRS to postpone certain tax-filing and tax-payment deadlines for taxpayers who reside or have a business in the disaster area. For instance, certain deadlines falling on or after Jan. 8, 2023, and before Oct. 16, 2023, are granted additional time to file through Oct. 16, 2023. As a result, affected individuals and businesses will have until Oct. 16 to file returns and pay any taxes that were originally due during this period. This includes 2022 individual income tax returns due on April 18, as well as various 2022 business returns normally due on March 15 and April 18. Among other things, this means that eligible taxpayers will have until Oct. 16 to make 2022 contributions to their IRAs and health savings accounts.

In addition, farmers who choose to forgo making estimated tax payments and normally file their returns by March 1 will now have until Oct. 16, 2023 to file their 2022 return and pay any tax due. The Oct. 16, 2023, deadline also applies to the quarterly estimated tax payments, normally due on Jan. 17, 2023 and April 18, 2023. This means that individual taxpayers can skip making the fourth quarter estimated tax payment, normally due Jan. 17, 2023, and instead include it with the 2022 return they file, on or before Oct. 16.

The Oct. 16 deadline also applies to the quarterly payroll and excise tax returns normally due on Jan. 31, 2023. In addition, penalties on payroll and excise tax deposits due on or after Jan. 8, 2023, and before Jan. 23, 2023, will be abated as long as the tax deposits are made by Jan. 23, 2023.

If an affected taxpayer receives a late filing or late payment penalty notice from the IRS that has an original or extended filing, payment or deposit due date that falls within the postponement period, the taxpayer should call the telephone number on the notice to have the IRS abate the penalty.

The IRS automatically identifies taxpayers located in the covered disaster area and applies filing and payment relief. But affected taxpayers who reside or have a business located outside the covered disaster area should call the IRS disaster hotline at 866-562-5227 to request this tax relief.
