Accounting & Tax Services in Alabama

Alabama secured $7 billion in new capital investment across 224 projects in 2024, creating over 8,500 jobs statewide. The state’s $321.2 billion GDP is powered by manufacturing, and Alabama is one of only five states where manufacturing has been the largest industry every year since 1990. From Huntsville’s Cummings Research Park, the nation’s second-largest research park with 400+ companies, to the Mercedes-Benz assembly plant in Tuscaloosa, business owners operate in a state built for industrial growth.

Alabama’s graduated income tax tops out at 5%, and the state is one of only three that allows a federal income tax deduction on state returns. S-Corp owners should evaluate the pass-through entity tax election to work around the federal SALT deduction cap. The business privilege tax applies to LLCs, corporations, and partnerships, requiring careful entity structuring to minimize combined state and federal liability.

SDO CPA works with Alabama business owners across aerospace, automotive manufacturing, healthcare, and government contracting to structure entities, optimize S-Corp reasonable compensation, and manage the interplay between Alabama’s graduated income tax and federal obligations. Whether you’re a defense contractor in Huntsville’s Research Park or an automotive supplier along the I-65 manufacturing corridor, we provide monthly bookkeeping and fractional CFO services scaled to your stage of growth.

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.

Alabama is home to 440,000+ small businesses and a population of 5,108,468. From Aerospace & Defense, Automotive Manufacturing, Healthcare to professional services, Alabama business owners need CPAs who understand government contract compliance and DCAA audit requirements and can provide year-round tax planning — not just compliance.
