IRS Form 2220 is used to calculate and report any penalty for underpaying estimated tax. File it when you didn’t pay enough tax through withholding or estimated payments during the year.
Plain English
If you owed more tax than you paid during the year, the IRS may charge a penalty. Form 2220 lets you figure out that penalty and tell the IRS why you think it should be reduced or waived.
