Accounting & Tax Services in New Hampshire, NH
New Hampshire’s business-friendly tax structure makes it one of the most attractive states in New England for entrepreneurs and business owners, with over 48,000 active businesses across the Granite State. The state charges no income tax on wages since the Interest & Dividends tax was fully repealed in 2025, creating a significant advantage over neighboring Massachusetts (5% flat tax) and Maine (up to 7.15%). However, New Hampshire’s dual business tax system requires careful planning: the 7.5% Business Profits Tax applies to net business income over $75,000, while the 0.55% Business Enterprise Tax hits the enterprise value tax base. For S-Corp and partnership owners, this creates a unique optimization challenge around how much income flows through as salary versus business profits. The Manchester-Nashua corridor drives much of the state’s technology and healthcare economy, while the Seacoast region around Portsmouth attracts professional services and tourism. SDO CPA helps New Hampshire business owners navigate the BPT/BET dual-tax system, structure entity elections to minimize combined federal and state taxes, and plan distributions that take full advantage of the state’s no-income-tax benefit on personal earnings.
New Hampshire Tax Planning Tip
New Hampshire eliminated its Interest & Dividends tax in 2025, meaning there’s now zero state tax on personal wages, interest, and dividends. However, businesses still face the 7.5% Business Profits Tax on net income over $75,000 and the 0.55% Business Enterprise Tax on the enterprise value tax base. For S-Corp owners, optimizing the balance between salary (not state-taxed) and business profits (state-taxed at 7.5%) is critical to minimizing your combined tax burden.
