The Colorado Tax Form is a crucial document for individuals navigating their state income tax obligations. This form, known as the DR 0104, is designed for full-year residents, part-year residents, and nonresidents who earn income from Colorado sources. Accompanying the main form are several related schedules and instructions that guide taxpayers through the filing process. Notably, the form includes the Voluntary Contributions Schedule (DR 0104CH), which allows taxpayers to contribute to various charitable organizations, and the Individual Credit Schedule (DR 0104CR), where eligible taxpayers can claim tax credits. Additionally, the Subtractions from Income Schedule (DR 0104AD) helps individuals identify certain deductions that can reduce their taxable income. For those who need more time, an extension payment form (DR 0158-I) is also available. It’s essential to be aware of the filing deadlines, typically set for April 15, and the specific mailing addresses for submissions, which differ based on whether or not a payment is included. Understanding the intricacies of the Colorado Tax Form not only ensures compliance but also maximizes potential refunds and minimizes tax liabilities.
