Under the gun? Filing extensions in each state
I’m hoping to have my taxes all ready without needing an extension this year, but maybe there are some extenuating circumstances that will prevent you from filing your federal taxes, and possibly your state taxes, on time.
Below I’ve assembled links to every state that has an individual state tax, with instructions on how to file an extension. Every state is unique, so be sure to check what your state needs you to do to file an extension, and follow the instructions carefully. You may need to copy federal forms to send in with your state return. You may need to provide a reason for the extension, and will not get the extension if you forget! You may need to estimate your taxes due. You may need to do the form online. The due date may be slightly different than the federal deadline.
The requirements from state to state (and DC, haven’t forgotten you guys!) aren’t wildly different, though, and there are several common threads throughout:
- For many of the states, you’re covered just by filing for a federal extension on time. That’s Form 4868. Be sure to check for your state’s specific instructions by following the link.
- Extra time to file does not mean extra time to pay. I didn’t see an exception to this anywhere. You still owe your taxes at the regular deadline, and can request a refund for the overage when you file.
- You may get a small reprieve for paying just most of what you owe on time. For some states, if you pay most of what you owe by the deadline and meet the requirements for filing an extension, you won’t owe penalties, but you’ll still owe interest on the unpaid amount until you pay. If you pass the extended deadline, they you’ll probably start accruing penalties again.
- If the state owes you money, they’re typically a lot more easy-going. Sometimes you don’t have to file anything to get an extension if you’re due a refund.
Anyway, here’s the table. Please verify by going through to the links that pertain to you!

Some state-specific notes on extensions:
- Arkansas. If you file a federal extension and it’s accepted, you do not need to file an Arkansas extension separately. The form is necessary only in the event that you want to get an extension for your Arkansas return, but not your federal return.
- Indiana. The state extension form only gives you an extra two months, but the federal extension form gives you until November 18th.
- Iowa. There is no form, and the state does not honor federal extension forms, but if at least 90% of the Iowa taxes are paid by the due date, there is an automatic extension to file.
- Kansas. A copy of the federal extension form must be submitted with your Kansas return for the extension to be valid.
- New Mexico. Usually extensions are granted for any reason up to 60 days after the normal deadline. Beyond that the reasons need to be better, presumably.
- New York. Extension request must be done online.
- North Dakota. A reason needs to be given, but filing a federal extension automatically extends the North Dakota filing.
- Ohio. The federal extension must be filed in Ohio. There is no Ohio-specific extension form.
- Oklahoma. For e-filers, you get an extra two days to file your taxes. The e-deadline is April 20th.
- Oregon. As with Arkansas, the form is necessary only in the event that you want to get an extension for your Oregon return, but not your federal return.
- Pennsylvania. The extension time is up to six months.
- Utah. No form is necessary, but there are prepayment requirements to get the automatic extension.
In summary, states want your money now, but they’ll usually give you a little extra time to get your return together if you just ask for it.

Question… maybe I missed it, or maybe I am going blind, or someone forgot us down here in the lone star state. I live in Texas and do not see Texas mentioned anywhere in the information above. Did you forgot about us down here?
Any info about Texas dates would be really helpful. Thank you!

Texas has no personal income tax, so there’s no need to file an extension. I think I included only those states that have an income tax.

Oh, OK. I appreciate that. Business owners do have a tax that is paid to the state and is extendable – separate from the IRS… so I am told. Recently moved here and learning the Lone Star State ropes.
Thanks for replying back.
