Trouble understanding avoiding underpayment penalty IRS 90%
Trouble understanding avoiding underpayment penalty IRS 90% Since I'm filing an extension, my estimate lets say would be $300k in federal taxes owed for last year. I can pay 270k and not get hit with the penalty and interest come time to file later this year? (i would obviously then be paying 30k when its my time to file later in the year). May seem silly but would appreciate any help. Thanks
