Mississippi splits trade licensing between the State Board of Contractors (MSBOC, which handles HVAC and electrical contractors above project-value thresholds) and the State Department of Health (which handles plumbing). The MSBOC threshold for HVAC is residential plus commercial projects above $50,000.
As of 2026, MSBOC delivers renewal notices by email only. If your registered email address on file is stale, you can miss your renewal entirely. Confirm your contact info is current in the MSBOC portal at least 60 days before your renewal date.
TradesIQ tracks Mississippi license renewals, CE hours, bonds, and insurance certificates in one dashboard — with automated reminders before anything lapses.
