Mississippi HVAC License Reciprocity

If you hold an active HVAC or mechanical contractor license in a neighboring state and want to work in Mississippi, reciprocity can shorten your path — but it doesn't eliminate the process. Mississippi's reciprocity agreements waive the technical trade exam only. Everything else — the application, the CPA financial statement, the Law and Business Management Exam, and the insurance requirements — still applies in full.

Here's exactly what reciprocity covers and where it stops.

Which States Have Reciprocity Agreements

The Mississippi State Board of Contractors (MSBOC) maintains reciprocity agreements with licensing boards in:

• Alabama
• Arkansas
• Louisiana
• Tennessee
• South Carolina

Each agreement has varying terms, but the core structure is the same: if you hold a comparable license in one of these states, you may qualify for a waiver of the technical trade examination.

Mississippi also participates in the Universal Recognition of Occupational Licensure Act (UROL), which recognizes out-of-state credentials for individuals who establish residency in Mississippi. This is a broader pathway that isn't limited to the five reciprocity states listed above.

What Gets Waived

Under reciprocity, the MSBOC waives the technical trade exam — the 80-question HVAC specialty exam or the 100-question Mechanical exam that Mississippi-based applicants must pass through PSI.

That's the only waiver. The trade exam waiver avoids the $120 PSI fee for that trade-exam portion, but the reciprocity process itself carries a $50 fee per exam waived. It also eliminates the need to study Mississippi-specific technical code references. But it's a narrow carve-out from a much larger process.

What Doesn't Get Waived

Everything else in the standard application process remains mandatory:

• The Mississippi Law and Business Management Exam. You must still schedule and pass this 50-question, 2-hour exam through PSI. It covers Mississippi-specific business law, contract management, and regulatory compliance. The NASCLA Contractors Guide — Mississippi Edition is the approved open-book reference.

• CPA-reviewed financial statement. Commercial applicants still need a balance sheet prepared by an independent CPA within the past 12 months, showing at least $20,000 net worth for the HVAC specialty or $50,000 for the Major Mechanical classification.

• Commercial general liability insurance. $300,000 per occurrence, $600,000 aggregate, with the MSBOC listed as certificate holder.

• The complete application package. Notarized application, three references, tax registration numbers, proof of the qualifying party's employment, and SOS registration (if operating as an LLC or corporation in Mississippi).

• The $400 application fee (for commercial) or $50 (for residential).

Reciprocity Eligibility Criteria

To qualify for a trade exam waiver under reciprocity, you must meet specific conditions:

1. Active, comparable license. Your out-of-state license must be in a classification comparable to the Mississippi classification you're applying for.

2. Written examination passed. You must have passed a written examination in the reciprocating state — licenses issued without an exam don't qualify.

3. Three years of continuous good standing. Your license must have been held in good standing for at least three consecutive years immediately before your Mississippi application.

4. Reciprocity Verification Form. You must submit a completed Reciprocity Verification Form that's filled out and signed by the licensing board in your home state. This verifies your license history and exam passage.

5. $50 fee per exam waived. The reciprocity verification itself carries a non-refundable fee of $50 for each exam portion being waived.

The UROL Alternative

The Universal Recognition of Occupational Licensure Act provides a separate pathway for out-of-state licensees who relocate to Mississippi. Under UROL, if you establish Mississippi residency and hold an active, equivalent license in another state (not limited to the five reciprocity partners), Mississippi recognizes the credential.

The UROL pathway still requires compliance with Mississippi-specific administrative requirements — you're not automatically exempt from the state's insurance, financial, and business registration rules. But it expands the pool of qualifying states beyond the traditional reciprocity partners.

Practical Considerations for Out-of-State Contractors

If you're an out-of-state contractor taking a single project in Mississippi rather than relocating, you still need the full licensing apparatus. Mississippi doesn't have a temporary permit or project-specific license for out-of-state contractors.

You also need to account for:

• State tax bonds. Out-of-state contractors must post a Department of Revenue tax bond on every Mississippi construction contract exceeding $10,000 — a requirement that in-state contractors only face on non-residential contracts above $75,000.

• Municipal registration. Each city where you perform work requires separate local registration, and many require a municipal contractor license bond ($5,000–$10,000 depending on the city).

• Secretary of State registration. If your business entity is an LLC or corporation formed in another state, you may need to register as a foreign entity with the Mississippi Secretary of State before the MSBOC will process your application.

The Mississippi HVAC License Guide includes the reciprocity verification checklist along with the out-of-state contractor tax bond requirements, so you can map out the full compliance path before committing to a Mississippi project.
