Your state and federal filing deadlines depend on where you live.
For most Americans, today, April 18, is the final day to file taxes without facing late fees or interest.
However, the IRS has given taxpayers in several states affected by tornadoes and other severe weather more time to submit their federal income tax returns.
And when it comes to state taxes, a majority of states adhere to the federal government's timetable, but some have their own schedule.
Here are all the dates you need to know for this tax season.

The official deadline to file federal tax returns is Tuesday, April 18, 2023.
That's because April 15 was a Saturday and Monday, April 17, was recognized as Emancipation Day in Washington, DC. According to the IRS, "by law, Washington, DC, holidays impact tax deadlines for everyone in the same way federal holidays do."
The agency has delayed the filing deadline in numerous states affected by severe weather conditions.
The full list of states and counties eligible for extensions is available on the IRS' Tax Relief in Disaster Situations website.
If you're serving in the military abroad you may also be granted additional time to file your return.
April 18 is still the deadline to file a tax extension with the IRS. Getting an extension doesn't change the payment deadline. It just gives you until Oct. 16 to complete the relevant paperwork.
You still have to submit any amount you owe on time to avoid late penalties.
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming do not collect income taxes.
Of the 41 states that do, most are adhering to the April 18 federal filing deadline. There are some exceptions.
California has extended the deadline for state returns for residents affected by severe weather conditions to May 18, 2023.
Taxpayers in Tennessee affected by the March 31 and April 1 storms have until July 31, 2023, to file.
To date, residents in other states with federal filing extensions must still file their state returns by April 18, 2023. In most cases, taxpayers can request an automatic filing extension but they will still have to make any outstanding payments by the original deadline.
