New Hampshire state law changes

November 1, 2026·Minimum Wage

New Hampshire Minimum Wage Legislative Review

New Hampshire's legislature may consider minimum wage legislation during the 2026 session, as the state currently follows the federal minimum wage of $7.25/hr with no state minimum wage law. Several proposals to establish a state minimum wage have been introduced in recent sessions. Employers should monitor legislative developments that could establish a state minimum wage above the federal floor.

Applies to: All New Hampshire employers

What to do: Monitor New Hampshire legislative developments regarding minimum wage proposals, prepare contingency plans for potential state minimum wage legislation, and ensure current compliance with the federal minimum wage of $7.25/hr.

Penalty: N/A (monitoring item)
