Accounting & Tax Services in Huntsville, AL

Huntsville has earned the title “Rocket City” for good reason. Home to NASA’s Marshall Space Flight Center and Redstone Arsenal, the city receives over $30 billion in annual federal investment. Cummings Research Park, the nation’s second-largest research park, hosts 400+ companies employing thousands of engineers, scientists, and defense contractors. With FBI and Space Command expansions underway and the second-highest concentration of engineers per capita in the country, Huntsville has become one of America’s fastest-growing technology hubs.

Defense contractors in Huntsville face specialized accounting requirements including DCAA compliance, indirect cost pool management, and government-specific billing standards. Alabama’s graduated income tax adds a layer of state planning on top of complex federal contract accounting. S-Corp owners working on classified programs or multi-site contracts also face unique reasonable compensation considerations when determining officer salaries across government and commercial revenue streams.

SDO CPA works with Huntsville defense contractors, aerospace startups at HudsonAlpha, and cybersecurity firms supporting Redstone Arsenal to structure entities for government contracting, optimize R&D tax credit documentation, and manage DCAA-compliant cost accounting. Whether you’re bidding on a NASA subcontract or scaling a tech startup in the Research Park, we provide monthly bookkeeping and fractional CFO services designed for contract-driven businesses.

Alabama Tax Planning Tip

Alabama’s graduated income tax tops out at 5% on income over $3,000 (single) / $6,000 (married). S-Corp owners should evaluate the pass-through entity tax election (PTET) to work around the federal SALT deduction cap. Alabama also offers a unique federal income tax deduction on state returns — one of only three states allowing this.

Huntsville is home to 18,000+ small businesses and a population of 220,461. From Aerospace & Defense, Technology, Engineering to professional services, Huntsville business owners need CPAs who understand navigating DCAA compliance and government contract accounting requirements and can provide year-round tax planning — not just compliance.
