New Hampshire Business Taxes Made Simple

Stay compliant and maximize tax benefits for your NH business.
New Hampshire has a unique business tax structure, offering no state income tax or sales tax. However, businesses must file the Business Profits Tax (BPT) and the Business Enterprise Tax (BET) if they meet income thresholds. Whether you’re a corporation, partnership, LLC, or sole proprietor, NH provides tax exemptions and credits, including the Research and Development Tax Credit, to support business growth.
