Who May Use this Form?
You may use the short method for 2210 penalty if:
You did not make any estimated payments; or
You paid the same amount of estimated tax on each of the four payment due dates.
You must use the regular method to calculate your 2210 penalty if:
You made any estimated payments late; or
You choose to annualize your income for 2210 penalty calculations.
Note: If any payment was made earlier than the due date for that payment, 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.
