Missing the tax deadline is not recommended. Remember, if you owe taxes this year, the payment is due to the IRS by April 15th, regardless of whether or not you have filed your actual tax return. Missing your payments can result in ugly penalties and interest charges. It’s best to file for an extension immediately, then try to get a rough idea of what you owe in taxes and make that payment as soon as you can. Even if you can only send in a partial payment, that will help reduce the amount of penalties and interest you owe.

Late filing penalties are high. The IRS will assess a late filing penalty of 5% of the unpaid taxes not paid by the due date for each month your taxes are late, usually to a maximum of 25%. It is very easy for late filing penalties to to reach several hundred or several thousand dollars. If your payment is more than 60 days past due, the minimum late filing penalty is $100 or the balance of the taxes you owe, whichever is less.

Late payment penalties and interest are also assessed when you do not send the IRS your tax obligation by the tax deadline. The late payment penalty is usually 0.5% of your unpaid taxes, with the maximum also at 25%. You may be able to have your late payment penalty waived if you paid over 90% of your obligation, however, you would still owe interest on the balance due. The interest stops accruing when you pay the balance. Translation – pay your taxes ASAP to avoid large penalties and fees!
