You see, if your tax payments are due

If you pay quarterly estimated taxes, usually makes the first three payments on the 15th day of each third month of April. However, if an estimated tax payment falls on a weekend these days, the IRS changes the schedule.

For the last part of the year you have a little more time. Instead, due on December 15, which is due on January 15, when it falls on a weekend or a holiday, it's a little longer

This is the scale of the anticipated fiscal year 2014 is the last payment of taxes for the year 2014 estimated tax due 15 January 2014.

First payment 15 April 2014
2nd payment June 16, 2014
