At some point every year, Americans begin scrambling as they try to figure out what forms they must file and when they must file them in the new tax season. The official deadline to file your federal income tax return each year can be a little shifty.
Yes, it's supposed to be April 15—unless something interferes with that timing, like the date falling on a weekend or a holiday. Whenever a tax deadline falls on a Saturday, a Sunday, or a legal holiday, it's typically moved to the next business day.
This doesn't happen in 2019, however. April 15 falls on a Monday and it's not a holiday, so the filing deadline for your 2018 tax return is indeed April 15 in 2019.
Here are some other important deadlines to keep in mind.
