When Are State Taxes Due? Most (but Not All) States Extended the Filing Deadline to May 17
You have an extra month to file your 2020 federal income tax returns, but taxpayers in some states have another deadline to mind: the deadline to file state income taxes.
Most states have followed the lead of the IRS, extending the deadline to file state income taxes to May 17 from April 15. But there are some exceptions (you can find details via a list compiled by the American Institute of Certified Public Accountants). Keep in mind that in most cases, extensions don't apply to estimated tax payments, which are still due April 15.
Here are the state tax deadlines for every state.
