Part I

Part II

Your penalty is lower when figured by treating the federal income tax withheld from your wages as paid on the 

dates it was actually withheld, instead of in equal amounts on the payment due dates. You must figure your penalty

and file Form 2210.

● If box B, C, or D applies, you must figure your penalty and file Form 2210.

Multiply line 4 by 90% (.90) 5

Part III

● You made any estimated tax payments late,

● You checked box C or D in Part II, or

10 Enter the amount from Form 2210, line 9 10

You must use the regular method (Part IV) instead of the short method if:

● You made no estimated tax payments (or your only payments were

withheld federal income tax), or

● You paid estimated tax in equal amounts on your due dates.

You may use the short method if:

● You are filing Form 1040NR or 1040NR-EZ and you did not receive

wages as an employee subject to U.S. income tax withholding.

Note: If any payment was made earlier than the due date, you may use the

short method, but using it may cause you to pay a larger penalty than the

regular method. If the payment was only a few days early, the difference is

likely to be small.

file Form 2210 unless

you checked a box in
