Late Filing of Return
The law provides a penalty of 5% of the tax due for each month, or part of a month, for which a return is not filed up to a maximum of 25% of the tax due (15% for each month, or part of a month, up to a maximum of 75% if the failure to file is fraudulent). If the return is more than 60 days late, the minimum penalty is the smaller of $135 or the tax due.
The penalty will not be imposed if you can show that the failure to file on time was due to reasonable cause. If you receive a notice about penalty and interest after you file this return, send us an explanation and we will determine if you meet reasonable-cause criteria. Do not attach an explanation when you file Form 1041.
