Deadline & Extensions

The filing deadline to submit 2023 tax returns or an extension to file is Monday, April 15, 2024, for most taxpayers. All tax due is owed by April 15, 2024. There is no extension to pay. If the tax owed is not paid by April 15, 2024, you will incur penalties and interest until the tax is paid in full.

The due date for filing your Arkansas Individual Income Tax return is April 15. If April 15 falls on a weekend or holiday, your return is due on the next business day. If you file a federal or State of Arkansas Extension and you file your return before the deadline, you will not be charged any late filing penalties for filing the tax return past the original due date. Interest and any applicable failure to pay penalty will be charged on all tax due returns from the original due date until the date you file the income tax return.

If you have already filed a federal extension, you do not have to file a state extension. The State of Arkansas will honor an accepted Federal extension, and your due date will be one month after the due date of the federal return. This is usually November 15th for annual filers and October 15th for Partnership returns. You will need to check the appropriate box on the front of your Arkansas return when you file.

Note: If you file an Application for Automatic Extension of Time (federal form 4868), you will not receive an approved copy back from the Internal Revenue Service.You will need to check the appropriate box on the front of your Arkansas return when you file.

If you want to file specifically for a State of Arkansas Extension, you must file Arkansas form AR1055. This form must be postmarked on or before April 15.
