For Calendar Year Filers the due date for your Virginia Income Tax Return is May 1. If the due date falls on Saturday, Sunday, or legal holiday, you may file your return on the next business day. The United States Postal Service postmark is used to verify the date your return is mailed. If you are a fiscal year filer, your return is due the 15th day of the fourth month, following the close of the fiscal year.
