Do I need to register for sales tax in both Maine and New Hampshire?

It depends on where you cross each state's economic nexus threshold (or have physical presence there). Maine's published threshold is $100,000, and New Hampshire's is not applicable (no statewide sales tax). You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither. Run the nexus calculator with your actual sales and confirm with each state's official source. Thresholds as of 2026-05-27.

When did economic nexus take effect in Maine and New Hampshire?

Maine's economic nexus rule took effect on 2022-01-01, and New Hampshire's effective date is pending verification. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.

Neither state has a transaction-count trigger — only the dollar threshold matters.

Maine — nexus note

Economic nexus in Maine triggers at $100,000 in gross sales delivered into Maine in the current or prior calendar year. No transaction count threshold.

New Hampshire — nexus note

New Hampshire sales tax nexus and economic nexus threshold: New Hampshire does not impose a statewide or local general sales tax, so remote sellers do not have a sales-tax economic nexus dollar threshold, transaction-count test, or general marketplace-facilitator collection threshold for retail goods shipped to New Hampshire customers. New Hampshire Department of Revenue Administration materials instead list targeted state-administered taxes such as Business Profits Tax, Business Enterprise Tax, Communications Services Tax, Meals and Rooms (Rentals) Tax, tobacco tax, real estate transfer tax, and property-related taxes. The Meals and Rooms tax is a separate 8.5% tax on restaurant meals, lodging, and motor vehicle rentals, not a general retail sales tax. Sellers with New Hampshire business activity or taxable meals, lodging, rental, communications, tobacco, or other special-tax activity should verify those separate registration duties with DRA.
