QUESTION: I have a large payment to make on my 2010 income tax return and you told me to pay it as late as 4/15/11. If I pay it on 4/15/11, the IRS will receive it after 4/15/11 so how can I prove the payment was made on time?
ANSWER: I recommend mailing it by U.S. certified mail. Under Regulation 1.7502-1(c)(2), your receipt is postmarked by the postal employee to whom the letter is presented and this receipt is proof of timely payment.
