The IRS is closing several individual payment post office boxes (or lockbox addresses) in San Francisco, CA, and Hartford, CT, areas beginning Jan. 1, 2022. Payments are currently being forwarded to Louisville, KY, and Cincinnati, OH, through Dec. 31, 2021. However, payments mailed to these closed payment locations after Jan. 1, 2022, will be returned to sender.
To help ensure timely receipt, the IRS encourages practitioners and taxpayers to avoid mailing to these closing addresses as there could be mail delays. Please check Where to File for active addresses before mailing your payments. If you receive an IRS payment letter, send your payment to the address located in the letter.
