When to file If you're a calendar year filer and your tax year ends on December 31, the due date for filing your federal individual income tax return is generally April 15 of each year. If you use a fiscal year (tax year ending on the last day of any month other than December), your return is due on or before the 15th day of the fourth month after the close of your fiscal year. If your due date falls on a Saturday, Sunday, or legal holiday, the due date is moved to the next business day. For the 2021 tax return, the due date is April 18, 2022 because of the Emancipation Day holiday in Washington, D.C. Taxpayers in Maine and Massachusetts have until April 19, 2022 because of the Patriots’ Day holiday in those states. Your return is considered filed on time if the envelope is properly addressed, has enough postage, is postmarked, and is deposited in the mail by the due date. If you file electronically, the date and time in your time zone when your return is transmitted controls whether your return is filed timely. You will later receive an electronic acknowledgement that the IRS has accepted your electronically filed return. If you served or are serving in the Armed Forces in a combat zone or a contingency operation, or become hospitalized as the result of an injury received while serving in such an area or operation, after the end of your tax year but before the normal filing due date of your return, you may have additional time to file and pay taxes. You generally have at least 180 days after you leave the designated combat zone/contingency operation to file and pay taxes. See Publication 3, Armed Forces' Tax Guide. If the Service determines you to be affected by a federally declared disaster, a significant fire or a terroristic or military action, you may have up to one year after the due date of your return to file and pay taxes, depending on the deadline specified by the Service. If you're living and working outside the United States and Puerto Rico or in the military or naval service on duty outside the United States and Puerto Rico, you may qualify for an automatic 2-month extension to file and pay the tax without filing Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. You will be charged interest on any amount not paid by the regular due date until the date the tax is paid. Please refer to “What if You Can’t File on Time?” in the Instructions for Form 1040 (and Form 1040-SR) and the instructions in Form 4868. Extensions to file - If you cannot file by the due date of your return, you should request an extension of time to file. To receive an automatic 6-month extension of time to file your return, you can file Form 4868. File your extension request by the due date of your return. An extension of time to file is not an extension of time to pay so you'll owe interest if the tax you owe isn't paid by the original due date of your return. You may also be subject to a late-payment penalty on any tax not paid by the original due date of your return. For more information about extensions, see Extension of Time to File, What Is the Due Date of My Federal Tax Return or Am I Eligible to Request an Extension? and Topic No. 304. How to file You may want to file your return electronically. You'll usually receive your refund within 3 weeks of the date when the IRS receives your return, even faster if you elect to have it directly deposited into your checking or savings account. Most professional tax return preparers offer electronic filing of tax returns with their return preparation services and may charge a fee to file your return electronically. Also, when you prepare your return yourself using tax-preparation software, you may have to pay a fee to file your return electronically. However, you may qualify for free electronic filing through Free File. For more information on electronic filing in general, visit Electronic Filing Options for Individuals. If you mail a paper Form 1040 or Form 1040-SR, it can take six to eight weeks to process.

Related schedules and forms behind your return in the order of the sequence number located in the upper right-hand corner of the schedule or form.

Be sure to also sign in the regular space provided for your signature. Attach a statement that includes the form number of the return you're filing, the tax year, the reason your spouse cannot sign the return, and that your spouse has agreed to your signing for him or her. If you're the guardian for your spouse who is mentally incompetent, you may sign the return for your spouse as "guardian." If your spouse cannot sign the return for any other reason, you may only sign it if you have a valid power of attorney. You should attach the document granting you power of attorney to the return. You may use Form 2848, Power of Attorney and Declaration of Representative for this purpose. If you're filing a return for a minor child who cannot sign the return, sign the child's name followed by the word "by," then your signature, and your relationship, such as "parent" or "guardian for minor child."
