You probably saw this:
April 20, 2019
Deadline for resubmitting or paper-filing a rejected federal return that was originally e-filed by the April 15 deadline if you
did not
file an extension.
- April 22, 2019, if you live in Maine or Massachusetts because of Patriot's Day.
-
Note: Although the last day to resubmit a rejected return is October 20, the April 20 deadline applies to taxpayers who owe taxes and want to avoid the late-filing penalty.
However, if your return has already been accepted, taxes come out on April 15 (unless you said an earlier date.)
