You can file your taxes for the 2024 tax year starting on January 27, 2025, when the IRS opens the e-filing system. The deadline to file your 2024 federal income tax return is April 15, 2025. If you need more time, you can file for an extension by the April deadline, which extends your filing time until October 15, 2025, without penalty as long as you file by then. However, you should pay at least 90% of your tax owed by the April deadline to avoid penalties.
