  • The corporation must make installment payments of estimated tax if it expects its total tax for the year (less applicable credits) to be $500 or more.

  • The installments are due by the 15th day of the 4th, 6th, 9th, and 12th months of the tax year. If any date falls on a Saturday, Sunday, or legal holiday, the installment is due on the next regular business day.

  • If the foreign corporation does not maintain an office or place of business in the United States, it may pay the estimated tax by EFTPS, providing it has a U.S. bank account. The foreign corporation may also arrange for its financial institution to submit a same-day payment on its behalf or can arrange for its qualified intermediary, tax professional, payroll service, or other trusted third party to make a deposit on its behalf using a master account. In addition, the foreign corporation still has the option to pay the estimated tax due by check or money order.

Estimated tax penalty. A corporation that does not make estimated tax payments when due may be subject to an underpayment penalty for the period of underpayment. Generally, a corporation is subject to the penalty if its tax liability is $500 or more and it did not timely pay at least the smaller of:

  • Its tax liability for the current year, or

  • Its prior year’s tax. No estimated tax payments are required with respect to a foreign corporation’s liability for the branch profits tax. See Regulations section 1.884-1(a).

Use Form 2220, Underpayment of Estimated Tax by Corporations, to see if the corporation owes a penalty and to figure the amount of the penalty. If Form 2220 is completed, enter the penalty on Form 1120-F, page 1, line 6. See the instructions for line 6, estimated tax penalty, later. Also, see Extension of relief from additions to tax for underpayments applicable to the corporate alternative minimum tax (CAMT), earlier.
