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.
You may send estimated tax payments with Form 1040-ES by mail, pay online, by phone or from your mobile device using the IRS2Go app. Visit Make a payment to view all payment options.
