At some point every spring, Americans remember that it’s tax season and many begin scrambling a little, trying to figure out what forms they must file and when. The official deadline to file your federal income tax return each year can be shifty. Yes, it’s supposed to be April 15 — unless something interferes with that timing, such as because April 15 falls on a holiday. Under a special rule, whenever a tax deadline falls on a Saturday, a Sunday or a legal holiday, it’s moved to the next business day.
That’s April 18 in 2017. You have until October 16, 2017 if you file a request for an extension on or before that date. Here are some other important deadlines to keep in mind.
