tax day

     

Tax Day is the common term for the ay on which tax returns (statements about income taxes) are due to the U.S. Federal Government and to the U.S. states from U.S. citizens, resident aliens, and certain nonresident aliens. More specifically, this is the last day on which tax returns can be mailed (as postmarked) to avoid penalties, with some exceptions. In the United States, Tax Day has usually been April 15 since 1955.
