Note: In most cases, the corporation does not need to file Form 2220. (See Part I below for exceptions.) The IRS will figure any penalty

owed and bill the corporation. If the corporation does not need to file Form 2220, it may still use it to figure the penalty. Enter the

amount from line 36 on the estimated tax penalty line of the corporation’s income tax return, but do not attach Form 2220.

The corporation is using the annualized income installment method.

The corporation is using the adjusted seasonal installment method.

The corporation is a “large corporation” figuring its first required installment based on the prior year’s tax.
