Figuring Estimated Tax Penalty
What form to use to figure out the estimated tax penalty for underpayment?
Form 2210, Underpayment of Estimated Tax by Individuals, Estates, and Trusts, is the
form used to figure underpayment penalties. However in most cases, you do not need to file Form 2210. The IRS will
figure the penalty for you.
Will the IRS send me a tax bill?
If you owe a tax penalty, the IRS will send you a bill. As long as you have filed your tax
return by the due date, the IRS will not charge you interest on the penalty if you pay by the date specified on the
bill. If you want the IRS to figure the penalty for you, complete your tax return as usual and leave the penalty
line (line 77 of Form 1040) blank.
The flow chart at the top of the form will tell you if you have to file Form 2210.
