Final answer:
To request a six-month extension for filing a federal income tax return, use IRS Form 4868. This form does not extend the time to pay taxes due, so any estimated taxes should be paid by the original deadline. Form 4868 can be filed electronically or by paper mail.
Step-by-step explanation:
To request a six-month extension to file your tax return, you would use IRS Form 4868, officially titled Application for Automatic Extension of Time To File U.S. Individual Income Tax Return. This form allows individuals to obtain an additional six months to file their federal income tax return. It's important to note that this is an extension to file, not an extension to pay any taxes owed. You should estimate and pay any owed taxes by the original due date to avoid potential penalties and interest.
When filing Form 4868, make sure you provide all the required information, including your name, address, Social Security number, an estimate of your tax liability, and any payments you are making. Attach your Form W-2 if you're employed and any other forms showing federal income tax withholding. Form 4868 can be submitted electronically or by paper mail.
