Penalties and interest don't calculate when e-filing an 1120 return
Understand why the application doesn't compute penalties and interest on Form 1120, Page 1, Line 34 when you enable electronic filing.
When you enable electronic filing (), the application doesn't compute penalties and interest for the Amount Owed on Form 1120, Page 1, Line 34.
The application suppresses this calculation because the IRS doesn't accept electronic files that contain pre-computed penalties or interest. Instead, the IRS computes the penalty and interest after receiving the electronic file and bills the taxpayer accordingly.
