Estimated Tax Payments for Corporations

Just like individual taxpayers, Corporations are responsible for making quarterly estimated tax payments. Corporations generally have to make estimated tax payments if they expect to owe tax of $500 or more when their return is filed.

Estimated tax payments for corporations are due by the 15th day of the 4th, 6th, 9th, and 12th months of the tax year. In other words, a corporation’s quarterly estimated tax payments are due on April 15th, June 15th, September 15th, and December 15th. (This differs slightly from an individual taxpayer’s estimated tax payment due dates, which are April 15th, June 15th, September 15th, and January 15th.)

If any due date falls on a Saturday, Sunday, or legal holiday, the installment is due on the next regular business day. For example, the next two estimated tax payments are due on September 16th, 2019 and December 16th, 2019 because the 15th falls on a Sunday in both cases.

A worksheet, Form 1120-W, is available to help corporations estimate their tax for the year.
