If taxes are paid by mail, you will avoid penalty and interest if the envelope bears an official post office date stamp not later than the last day to pay in person. A metered postmark is not acceptable.

The IRS imposes a fine if you underpay your estimated taxes. You have to pay the taxes due plus a percentage penalty for each day your estimated taxes went unpaid. This percentage is set by the IRS each year. In recent years, the penalty has ranged from 6% to 8% annually.
