The Colorado Department of Revenue typically begins accepting state income tax returns around the same time as the federal Internal Revenue Service, generally in late January or early February each year. Specific dates are announced annually and publicized through the Department’s official website and media outlets. Taxpayers can begin preparing their returns beforehand, gathering necessary documents such as W-2s and 1099s.
Filing a timely and accurate return is crucial for several reasons. It allows taxpayers to receive any refunds they may be entitled to promptly. Furthermore, timely filing avoids potential penalties and interest for late submission. Understanding the filing window provides individuals and businesses adequate time to organize their financial records and seek professional assistance if needed. The state relies on collected tax revenue to fund essential public services, including education, infrastructure, and healthcare.
