Reasonable cause for failure to file a timely and complete partnership return will be presumed if the partnership (or any of its partners) is able to show that all of the following conditions have been met:
If all of the above conditions are met, you may return this notice with your statement, signed under penalty of perjury, that you qualify to have the penalty removed for reasonable cause under the provisions of Rev. Proc. 84-35.
The penalty can be reasserted if it was removed based on a statement with respect to Rev. Proc. 84-35, and it is later determined that such statement was false in any material respect. Additionally, a penalty for making false statements may be asserted under IRC section 7206.
Take necessary steps to prevent a similar penalty in future years.
