Colorado State Income Tax
Understanding state income tax is crucial for anyone living in or moving to Colorado. In this comprehensive guide, we will explore the intricacies of the state income tax in Colorado, providing valuable insights and detailed explanations on various aspects of the tax system.
Overview of Colorado State Income Tax
Colorado employs a flat state income tax, meaning that regardless of income level, individuals are taxed at the same rate. This rate is consistent across all taxpayers, making it relatively straightforward compared to states with progressive tax systems where rates increase with higher income levels.
Current Tax Rate: As of 2021, the state income tax rate in Colorado is 4.55%. This rate applies to both individual and corporate taxpayers. It's important to note that tax laws can change; therefore, staying updated on current rates via official state resources is wise.
