When Are Corporate Estimated Tax Payments Due?

Corporate estimated tax payments are, in general, due by the 15th day of the tax year's 4th, 6th, 9th, and 12th months. If the due date falls on a weekend, or a legal holiday, the installment payment is due on the next business day.

Some corporations are required to electronically deposit all depository taxes, including the federal corporate estimated tax payments. If the estimated tax payments are not done by the due date, the corporation may be subject to an underpayment penalty for the underpayment period. Use Form 2220 to see if the corporation owes a penalty and to figure the penalty amount.
