Quarterly Payments

For estimated tax purposes, the year is divided into four payment periods. Each period has a specific payment due date. If you don't pay enough tax by the due date of each payment period, you may be charged a penalty even if you're due a refund when you file your income tax return at the end of the year.

If you mail your estimated tax payment and the date of the U.S. postmark is on or before the due date, the IRS will generally consider the payment to be on time. If you use IRS Direct Pay, you can make payments up to 8 p.m. Eastern time on the due date. If you use a credit or a debit card, you can make payments up to midnight on the due date.
