How do I file an extension

[CatinaT1]

It depends on what program you are using. See your options here: How do I file an IRS tax extension? - TurboTax Support - Intuit

 This will extend the time you have to file your taxes until October 15th, 2025.  

Also, you may have to do your state taxes: Do I need to file an extension for my personal state taxes?  

Remember, an extension gives you more time to prepare your taxes, but it doesn't extend the time to pay your taxes.  If you have an indication that you will owe taxes, you should make the payment by the original due date of the tax return to avoid additional interest and penalties.

It is too late to request an extension---you had to do that by midnight on 4-15-2025.   Now your return will just be late unless you happen to live in one of the federally declared disaster areas that have additional time.  If you are in one of those areas, the IRS will identify that  when you file the return.
