Does Filing a Tax Extension Include State Taxes?

Filing a Form 4868 or 2688 for an automatic extension of time with the Internal Revenue Service gives the federal taxpayer more time to prepare a tax return. It doesn't give more time to pay taxes but prevents penalties for not filing in a timely manner. Certain states consider filing a federal income tax extension sufficient for obtaining an extension for state income taxes.

File Form 4868 or 2688

You must file Form 4868 or 2688 by April 15 to obtain an extension. If you owe a balance on your federal income taxes, these forms don't extend the time to pay. If you can't pay the entire balance, the IRS suggests you pay what you can to avoid penalties and interest. States also require timely payment of taxes; an extension only extends the time to file.

No State Income Tax, No Extension

Texas, Alaska, Washington, Nevada, Wyoming, Florida and South Dakota have no income tax, so an extension is not at issue. No extension exists in Iowa. California and Colorado give an automatic extension to file, but tax is due April 15. Illinois and Utah require no extension if you owe no tax. New Hampshire doesn't require an extension if you owe no tax, but DP-59-A is the correct form to use if you owe taxes.
