Late to file income tax return? Make sure to file a federal tax extension form. This income tax extension form can be filed online or through the mail. Download the form 4868 first, print it, fill it out, and mail it before April 15th.
Filing a federal tax extension form gives you more time until October 15th to file your federal income taxes; however, filing an extension does extend the time to pay. You are still responsible for estimating any income tax due and sending the IRS at least 90 percent to avoid paying penalties.
If you cannot pay your income taxes, it's still important to file an extension to avoid extra fees and penalties for not filing on time.
