New Hampshire, specifically
No income tax, but New Hampshire taxes business profits.
New Hampshire taxes neither wages nor self employment income, which is why the state line above reads zero. It taxes business profits instead, and a sole proprietorship counts. The Business Profits Tax statute defines a business organization to include a proprietorship and imposes the tax at 7.5 percent for taxable periods ending on or after December 31, 2023. A return is required from every business organization with gross business income above $92,000 in the taxable period. The statute directs the commissioner to adjust that threshold for inflation every two years, so the operative figure for your year comes from the Department of Revenue Administration, not from here.
- A sole proprietorship is a business organization under the statute. The tax is not a corporations only tax.
- Gross business income is defined without any deduction for the cost of materials, labor, interest, taxes or other expense, so the filing threshold is measured on revenue rather than profit.
- The statutory threshold is $92,000, adjusted biennially against the regional Consumer Price Index. Confirm the current figure with the Department of Revenue Administration.
