If you get an extension, you'll have until Tuesday, Oct. 15, 2024 to file your return.

According to the IRS:

Can I file my taxes for free on Tax Day?

Yes! More people are filing their taxes using Free File this year, the IRS said.

Free File allows any taxpayer with an adjusted gross income of $79,000 or less in 2023 to file taxes for free through one of eight IRS partners. To access the service, go online at IRS Free File and use the guided software.

If you're eligible, a free filing can save you a pretty penny. An individual taxpayer is estimated to spend 13 hours and $240 in out-of-pocket costs to prepare and file an annual tax return, according to the Taxpayer Advocate.
