Note that a penalty is assessed against the Partnership if it is required to file a partnership return and it (a) fails to file the return by the due date, including extensions, or (b) files a return that fails to show all the information required, unless such failure is due to reasonable cause.
The penalty is $210 for each month or part of a month (for a maximum of 12 months) the failure continues, multiplied by the total number of persons who were partners in the partnership during any part of the partnership's tax year for which the return is due.
