IRS Announces Updated Mailing Addresses for Key Tax Forms

With recent updates to IRS Publication 3891, taxpayers in certain states must now mail payments and filings for 1040-ES, 1040-V, and Form 941 to a new mailing address.  Although the publication is dated 2026, these changes are effective immediately for all future filings.  Only the states listed below are affected by this change.

The IRS has indicated that any returns and payments sent to the wrong address will automatically be forwarded and no late penalties will be imposed. However, please scan the list below for your home state and update the mailing addresses accordingly.
