Here is a calculator to see if you qualify for the US ESP. By some reports if you file your Fed taxes by April 15 - Tax Day. The Feds would mail your check out by May 2. Or between May 2 and May 16. While some will recieve them as late as the 2nd week in July. So see if you qualify. You neve know, Right?
