State of Colorado Personal Income Tax Extensions

E-file an IRS personal tax extension with TaxExtension.com

General Instructions

Colorado personal income tax returns are due by April 15. If you cannot file by that date, you can get an automatic state tax extension. A Colorado personal extension will give you 6 extra months to file, moving your deadline to October 15.

There is no form or application to request a tax extension from the State of Colorado. The only requirement is that at least 90% of your tax liability must be paid by the original deadline (April 15) to avoid late fees.

You can mail your state tax payment using Colorado Form DR 0158-I (Payment Voucher for Automatic Colorado Extension for Individuals). Note that you are not required to file Form DR 0158-I if you electronically pay your state tax liability online. To make an electronic state tax payment, you can go to Colorado’s “Revenue Online” system: www.colorado.gov/revenueonline

If you are unsure whether you need to make a state tax payment, use the worksheet on Form DR 0158-I to determine if you owe Colorado tax this year.
