Accounting & Tax Services in Indianapolis, IN
Indianapolis is Indiana’s capital and economic engine, with over 38,000 businesses generating more than $150 billion in annual economic output. Eli Lilly’s $3.7 billion manufacturing expansion and Salesforce’s 48-story downtown tower anchor a growing life sciences and technology corridor along the White River and Mass Ave districts. The city’s motorsports industry surrounding Indianapolis Motor Speedway generates $500 million annually, supporting hundreds of engineering and hospitality businesses. Downtown’s Mile Square and the Bottleworks District attract new restaurants, creative firms, and co-working spaces. However, Marion County’s 2.02% county income tax is among Indiana’s highest, adding $2,020 per $100,000 of income on top of the 3.05% state rate. Many business owners don’t realize they could save significantly by structuring operations to allocate income outside Marion County. SDO CPA helps Indianapolis businesses optimize their county tax exposure, capitalize on life sciences R&D credits, and structure entities to minimize the combined 5.07% state-plus-county effective rate.
Indiana Tax Planning Tip
Indiana’s 3.05% flat income tax is among the lowest in the Midwest, but county income taxes add 0.5% to 2.9% on top, varying significantly by location. Hamilton County (Carmel, Fishers, Noblesville) charges 1.0%, while Marion County (Indianapolis) charges 2.02%. Choose your business location strategically, and ensure your entity structure minimizes both state and county tax exposure.
