Accounting & Tax Services in Aurora, CO

Aurora’s economy centers on the University of Colorado Anschutz Medical Campus, which generates $6.8 billion in annual economic impact and employs over 18,000 healthcare professionals, making it Colorado’s largest employment center for medical research and bioscience. Healthcare businesses in the Fitzsimons Innovation Community face complex tax issues including physician practice entity structuring, medical equipment depreciation strategies, and research collaboration accounting. Aurora spans three counties (Adams, Arapahoe, and Douglas) with varying sales tax rates—Aurora’s own 3.75% city rate plus county and special district additions totaling 8.0% to 8.3% depending on location. Retail businesses along East Colfax Avenue and the Aurora Town Center must track sales tax nexus across multiple jurisdictions. Manufacturing and logistics companies near Denver International Airport deal with inventory accounting and interstate commerce apportionment issues.

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.

Aurora is home to 28,000+ small businesses and a population of 393,292. From Healthcare, Retail, Manufacturing to professional services, Aurora business owners need CPAs who understand Managing tax compliance for businesses operating in both Aurora and Denver with different sales tax jurisdictions and filing requirements across city boundaries and can provide year-round tax planning — not just compliance.
