How to File for an Extension of State Taxes
While the IRS requires you to file Form 4868 to request a tax extension, each state has its own requirements for obtaining a similar extension.
When a significant natural disaster hits – such as a hurricane, earthquake, tornado, flood, wildfire, blizzard, or the like – the IRS will extend upcoming federal tax deadlines for affected taxpayers if a federal disaster is declared. The extended due dates apply to most federal tax returns and payments, including those for income taxes (including estimated tax payments), payroll taxes, and excise taxes. If you’re impacted by a natural disaster, check our IRS Disaster Relief page to see if you qualify for an automatic tax filing or payment extension.
Key Takeaways
- Some states—including Wisconsin, Alabama, and California—allow you to file your state income tax return after the deadline without requesting an extension.
- In states without an automatic extension, you need to file the state’s specific form to obtain the extension.
- After being granted an extension, your state tax return usually is due by October 15.
- An extension of time to file your state income tax return isn’t an extension to pay any taxes you may owe.
State tax extensions
While the IRS requires you to file Form 4868 in order to request a tax extension, each state has its own requirements for obtaining a similar extension. Some states such as California offer automatic extensions to all taxpayers, while other states require you to file a specific form by the original due date of the return. Here are some tips to help walk you through what you need to do when filing state taxes in your area:
Step 1: Check-in with your state tax authority
Some states including Wisconsin, Alabama and California offer automatic extensions to file your state income tax return without having to file any additional forms. Other states, such as New York, will grant you a extension but you must request it. For the nine states that do not impose a state income tax, you don’t even have to file an income tax return, let alone request an extension. Reach out to your state tax authority to confirm which steps you will need to follow.
Step 2: File the appropriate state tax form
Unlike IRS Form 4868, which applies to all taxpayers throughout the country, you must file the correct state-specific form to obtain the extension. TurboTax also offers TurboTax Easy Extension, an online tool that allows you to file extensions for both your federal and state tax returns.
TurboTax Tip:
If you file with TurboTax, there’s a direct link to file your state extension when you go to complete your state return. Otherwise, download your state extension form by selecting your state from the list at: “How do I file an extension for my personal state taxes?”
Step 3: Pay any estimated taxes by the original due date of the return
An extension of time to file your state income tax return does not also mean an extension to pay any taxes you may owe. If you end up owing owe tax at the end of the year, you may be subject to late-payment penalties if you fail to submit a payment by the original tax deadline. To avoid paying any penalties, it’s a good idea to calculate a quick estimate of what you might owe and submit a payment. Even if you overpay, you can always claim a refund in a few months when you eventually file your state tax return.

Step 4: Submit your return by the extension deadline
In most cases, your state tax return is due by October 15 after you file for an extension. However, if you fail to file a complete return by this date, your state may charge you penalties just for filing your return late.
