When Are Income Taxes Due?

Federal and state income taxes for calendar year 2017 are due April 17, 2018 in most states. In a handful of states, income taxes are not due until later, April 30, 2018, for example. Most state income tax returns will refer to the income, adjustments, and credit amounts on your federal income tax return. For this reason, it's important that you prepare your federal income tax forms in advance of trying to prepare your state income tax forms.

2018 Federal and State Tax Due Dates

In the table below you will find the 2018 income tax due dates by state for the 2017 calendar tax year. We have included the Regular Due Date alongside the 2018 Due Date for each state in the list as a point of future reference. Each calendar year the state income tax due date may differ from the Regular Due Date because of a state recognized holiday, or the due date falls on a Saturday or Sunday, for example. Income tax returns must be postmarked before or on the 2018 filing due date to avoid penalties and late fees.

Missed The 2018 Federal And State Tax Due Date?

If you can not complete your federal and state income taxes before the 2018 filing deadline, you are generally expected to mail in an extension of time to file request form and make an estimated payment prior to the filing due date. You can then send in your federal and state income tax return a bit later with interest and possibly penalty charges forthcoming.

If you do not have the money to pay your income taxes due, then you generally must file your federal and state income tax return without a payment. Once the IRS and state department of revenue have processed your income tax return, you can request a payment schedule from them by mail-in form or by phone if necessary. Read the published IRS 1040EZ, 1040A, 1040 and state income tax instructions booklet for more details.
