TAX RETURNS
How to file
- Online - The Taxation Division encourages Taxpayers to file electronically to cut down on processing time and the potential for errors as well as issues in transit. Taxpayers can currently file with one of the many third-party vendors who offer certified electronic income tax filing products. Corporate and Partnership income tax processing will be available in the coming days.
- By mail - Instructions about filing State income tax are available on each form.
The tax filing deadline for calendar year filers for 2024 is April 15, 2025; however, the state offers an automatic six-month extension for filing as long as payment obligations are satisfied by April 15.
How to save money
The Taxation Division’s new, online tax benefits information hub can help Taxpayers save potentially thousands of dollars. Found at Tax.Colorado.gov/SaveMoney, the new online resource offers tax benefits information in an easy-to-understand format and is organized into four high-impact tax groups: families and individuals, seniors and retirees, charitable contributions and climate-friendly.
These four groups house dozens of tax credits and subtractions available to eligible Taxpayers. Many of these credits are refundable and can benefit qualifying individuals and businesses, even if they have little or no state tax liability.
