New Hampshire Privacy Law Overview

New Hampshire's privacy law took effect January 1, 2025. It follows the mainstream multistate model with full consumer rights and opt-in sensitive-data consent, but its low 35,000-resident threshold means many smaller businesses serving New Hampshire are covered.

The New Hampshire Privacy Act (NHPA)

New Hampshire's law provides comprehensive access, correction, deletion, portability and opt-out rights with opt-in consent for sensitive data. Its relatively low thresholds bring many mid-sized businesses into scope, and the Secretary of State was directed to adopt rules on the form of privacy notices.

NHPA: Quick Overview

  • Effective Date: January 1, 2025
  • Citation: N.H. Rev. Stat. Ann. ch. 507-H
  • Enforced By: New Hampshire Attorney General
  • Maximum Penalty: Up to $10,000 per violation
  • Private Right of Action: No (enforcement by the state only)
