Accounting & Tax Services in Merrimack, NH
Merrimack is one of southern New Hampshire’s fastest-growing communities, adding 2,532 residents (9.4% growth) since 2020, with over 1,300 businesses operating along the Daniel Webster Highway and Continental Boulevard corridors. Fidelity Investments maintains a major campus here employing thousands of workers, creating a satellite economy of financial services, IT consulting, and professional service firms. The Merrimack Premium Outlets and surrounding retail along Route 3 draw shoppers from across the region. Anheuser-Busch’s Merrimack brewery is a significant employer and tourism draw. The town’s relatively lower property tax rate compared to Nashua and Manchester makes it attractive for businesses seeking more affordable commercial space without sacrificing access to the I-93/Route 3 corridor. Merrimack’s rapid growth has created strong demand for healthcare services, home improvement contractors, and personal services. SDO CPA helps Merrimack business owners plan around stock compensation from employers like Fidelity, structure growing businesses for BPT optimization, and manage the tax implications of the town’s expanding commercial 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.
