New Hampshire retainage

Retainage in New Hampshire — Sources checked

Who and what this applies to

State-agency retained payments under RSA 21-I:20 and NHDOT federally assisted contracts under its DBE program.

Thresholds and scope

RSA 21-I:20 applies to state-agency contracts exceeding $500,000 with retention pending acceptance.

The rules

  • A covered contractor can withdraw retention by depositing permitted securities with the State Treasurer: initial deposit at least $10,000, each security at least $5,000, and withdrawal no more than the lesser of market or par value. Income goes to the contractor, subject to contractual deductions. Source
  • NHDOT’s DBE program declines retention from prime contractors and prohibits primes from retaining subcontractor payments in its federally assisted contract provisions. Source
