What is the deadline to file state taxes in Colorado?

The deadline to file state taxes in Colorado generally coincides with the federal tax deadline, which is typically April 15 of each year. However, if April 15 falls on a weekend or a holiday, the deadline may be adjusted to the next business day. It is important to note that taxpayers who need additional time to prepare their returns can file for a six-month extension, making the extended deadline September 15. This extension applies to filing the state tax return but does not extend the date for any tax payments that may be due. Taxpayers are encouraged to check the Colorado Department of Revenue website for the most current and accurate information regarding deadlines, as well as any changes that might occur due to specific circumstances in a given tax year.
