Accounting & Tax Services in Dover, NH
Dover is the Seacoast region’s fastest-growing city, with over 1,600 businesses thriving in a community that blends historic New England character with a modern startup culture.

Wentworth-Douglass Hospital, part of the Mass General Brigham system, is the largest employer and draws medical professionals from across the region. The Dover Industrial Park along Sixth Street hosts manufacturing and distribution firms, while the city’s proximity to the University of New Hampshire in Durham (just 8 miles away) provides a steady pipeline of educated workers. Dover’s housing market has tightened significantly, pushing commercial lease rates up but also creating demand for property management and real estate services. SDO CPA helps Dover business owners structure startup entities for growth, maximize R&D credits for technology firms, and plan commercial property investments in the city’s appreciating real estate market.
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.
