When making a 1-time tax payment to the IRS, because of a 1-time cash windfall, how does that factor into my taxes during tax time? Do I get a form or receipt of the 1-time payment that I enter somewhere on my 1040?
Just talked to an IRS person over the phone. They informed me that you don't get a receipt or anything when making a direct IRS payment, beyond a confirmation number. But I do enter the amount paid on line 65 of my 1040 Federal Tax Return form when I do my end of the year taxes.
