What forms do I need to complete for my Colorado state taxes?

Asked 2 years ago
For Colorado state taxes, individuals typically need to complete the Colorado Individual Income Tax Return, which is known as Form 104. Depending on your specific tax situation, you might need to include additional forms or schedules along with the main Form 104. For instance, if you are claiming certain tax credits or deductions, such as the Earned Income Tax Credit, you may need to fill out additional forms such as the DR 0104AD or the DR 0226 for active duty military members. If you are a business owner or self-employed, your tax obligations may require different forms, such as the Colorado Corporate Income Tax Return (Form 112) for corporations, or additional schedules for partnerships. Also, there are forms specific to certain types of income or tax situations, such as those related to rental income, capital gains, or retirement distributions. It is prudent to visit the Colorado Department of Revenue's website for the most current information on required forms tailored to your circumstances and for any updates on tax laws or forms for the current tax year.
