Accounting & Tax Services in Colorado, CO
Colorado’s business landscape is defined by its diverse economy spanning aerospace manufacturing in the Front Range, energy production in the Western Slope, and a booming technology sector centered in Denver and Boulder. The state’s 4.4% flat income tax rate creates tax planning simplicity compared to states with graduated brackets, but Colorado’s sales tax complexity—with over 70 home-rule cities maintaining separate rates and filing systems—creates significant compliance burden for multi-location businesses. Cannabis businesses face additional federal-state tax conflicts under IRC 280E, requiring specialized accounting. SDO CPA serves Colorado business owners statewide with expertise in multi-jurisdiction sales tax compliance, entity structuring under Colorado’s flat tax system, R&D credit optimization for aerospace and tech companies, and partnership tax planning for real estate ventures in Colorado’s competitive mountain resort markets. Our remote-first approach means Denver startups, Colorado Springs defense contractors, and Boulder SaaS companies receive the same sophisticated tax planning regardless of location.
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.
