2014 Federal Estimated Income Tax Payment Coupon (IRS Form 1040-ES): Like every year before ths, 1040-ES payments are due on the 15th day of the 4th, 6th, and 9th months of your tax year and on the 15th day of the 1st month after your tax year ends. (FYI: For the majority of individual taxpayers, the tax year ends on December 31.)
Please note that if the 15th happens to fall on a Saturday, Sunday, or a Government Holiday, then your payment is going to be due on the following business day—like the 2014 September installment listed below falls on Monday the 16th because the 15th is Sunday.
The due dates are also always printed on the 1040-ES payment coupon that must accompany your estimated tax payment.
