Accounting & Tax Services in Colorado Springs, CO

Colorado Springs hosts the nation’s second-largest concentration of defense contractors and aerospace businesses, with Peterson Space Force Base, Schriever Space Force Base, Fort Carson, and the Air Force Academy driving an estimated $9.3 billion annual economic impact. Defense contractors in the Powers Corridor and Briargate face unique tax challenges including Cost Accounting Standards (CAS) compliance, federal contract indirect cost rate calculations, and allowability determinations under FAR regulations. Colorado Springs businesses pay a combined 8.25% sales tax rate and must navigate Colorado’s complex economic nexus rules when serving out-of-state government contracts. Tourism businesses near Garden of the Gods and Pikes Peak deal with seasonal revenue fluctuations requiring careful cash flow and estimated tax planning. SDO CPA serves Colorado Springs business owners with specialized expertise in government contract accounting, R&D credit optimization for aerospace engineering firms, entity structuring for defense contractors (S-Corp vs. C-Corp analysis under the flat 4.4% Colorado rate), and partnership taxation for real estate developments serving the military community.

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.

Colorado Springs is home to 42,000+ small businesses and a population of 483,956. From Defense, Aerospace, Tourism to professional services, Colorado Springs business owners need CPAs who understand Navigating complex federal contract accounting requirements and government compliance regulations for defense contractors serving nearby military installations and can provide year-round tax planning — not just compliance.
