How New Hampshire taxes a business sale
- Income tax
- No broad-based individual income tax.
- Long-term capital gains
- No state tax on an individual's capital gains. The Interest and Dividends Tax (3% in 2024) never reached capital gains and is repealed for periods beginning after Dec 31, 2024.
- Entity-level taxes
- New Hampshire's Business Profits Tax and Business Enterprise Tax apply to business organizations, so an asset sale inside the company can be taxed at the entity level; an individual's sale of stock is not.

Methodology and sources
New Hampshire figures are for tax year 2026. Interest and Dividends Tax repealed for taxable periods beginning after Dec 31, 2024; no individual income tax in 2026.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.
