Can I Extend My State Tax Return Too?

Most states automatically accept the federal extension, meaning if you filed Form 4868 for your federal return, your state return is also automatically extended. However, some states require you to file a separate extension form, and most states still require you to pay any state taxes owed by the original due date to avoid penalties and interest — just like the federal extension. A few states have their own fixed deadlines that differ from the federal deadline. Check your state's department of revenue website for the specific rules. Even if your state accepts the federal extension, confirm the deadline doesn't require a separate filing step.
