If you are set up to make estimated tax payments, the address to send 3rd and 4th quarter Federal estimates to is as follows:
Internal Revenue Service
P.O. Box 802502
Cincinnati, OH 45280-2502
The IRS had planned to close a few locations by the time 3rd quarter estimates were do. The above address is where Minnesota residents should mail their estimate payments. Sorry about the confusion this year, and thank you for your patience.
