can i file an extension on my taxes last year but didn't file on time
You will probably face two types of penalties: one for not filing or efiling a tax return or extension on time, and one for not paying your taxes on time. The failure-to-file penalty is 5% of your balance due for every month (or part of a month) in which your taxes go unpaid.he failure-to-file penalty amount will be reduced by the amount you owe for failure-to-pay. The maximum amount you will owe for filing late will be 25% of your unpaid taxes. If you file more than 60 days late, your minimum failure-to-file penalty will be 100% of your unpaid taxes or $135 (whichever is smaller).
