How Indiana taxes a business sale

Income tax
Top rate 2.95%: Flat rate on all Indiana adjusted gross income.
Long-term capital gains
Capital gains are taxed as ordinary income at the flat 2.95% state rate plus the county income tax; no exclusion or preferential rate.
Entity-level taxes
S corporations generally pass income through; Indiana has an elective pass-through entity tax.
Local taxes
Every county levies a local income tax on residents' Indiana AGI, including capital gains, based on county of residence on January 1. 2026 rates run from 0.5% (Porter) to 3.0% (Randolph); Marion County (Indianapolis) is 2.02%.

Methodology and sources

Indiana figures are for tax year 2026. State rate fell from 3.0% to 2.95% for 2026 (scheduled cut; 2.9% scheduled for 2027). County rates are from DOR Departmental Notice #1, revised effective October 1, 2026. The examples assume a resident individual selling privately held stock for a long-term gain equal to the sale price (zero basis), with every dollar taxed at the top marginal rates, the federal 20% capital gains rate and the 3.8% net investment income tax, and no planning, credits or local taxes. Full assumptions are in the report methodology.
