Colorado Tax Planning Tip

Colorado’s flat 4.4% income tax rate applies to both individuals and corporations equally. For S-Corp owners, pass-through income is taxed at this flat rate with no brackets to worry about. However, Colorado’s patchwork of local sales tax jurisdictions — over 70 home-rule cities with their own rates — makes sales tax compliance complex. Use Colorado’s Sales & Use Tax System (SUTS) to simplify multi-jurisdiction filing.
