Mississippi contractor workers' comp is priced by the same formula as every other class of business: (payroll ÷ 100) × trade class-code rate × experience mod. Contracting rates sit on the higher end — well above a clerical office or a restaurant — because trade work carries real fall, struck-by, and equipment exposure. In 2026, a small clean-record trades contractor might pay from the high single-digit thousands a year, while a roofing crew, a larger general contractor, or a contractor carrying a high mod can run into the tens of thousands. What sets your number is your payroll, the governing trade class code, and your experience mod — and because Mississippi lets carriers file their own loss cost multipliers, which carrier quotes you moves the price meaningfully.
Every workers' comp premium starts the same way. Take your annual payroll, divide by 100, multiply by the rate for your trade class code, then multiply by your experience modification factor. For a contractor, the field crew is rated on the trade code that describes the dominant operation, while a handful of standard exceptions (clerical, outside sales) are carved out and rated on their own much lower rates. That's why "what does contractor comp cost in Mississippi" comes back to which trade governs your crews, how much payroll runs through it, and whether subs, overtime, and standard exceptions are handled correctly.
There is no one "contractor" code — the trade drives the rate, and the spread between trades is large. Common Mississippi contractor codes include:
The governing trade classification is the single biggest rating call on a contractor policy. Put a roofing operation in a carpentry code and the audit reclassifies you and bills the difference; put general carpentry into a higher structural code and you overpay all year. This is worth getting right up front, with an agent who knows how the carrier reads your scope of work.
Say a Mississippi commercial carpentry contractor runs $600,000 of field payroll in the 5403 code and $70,000 of correctly split-out clerical payroll. If the commercial-carpentry rate is roughly $6.50 per $100 of payroll and clerical is around $0.20, the manual premium looks like this:
| Payroll bucket | Payroll | Rate / $100 | Manual premium |
|---|---|---|---|
| Field crew (5403) | $600,000 | $6.50 | $39,000 |
| Clerical (8810) | $70,000 | $0.20 | $140 |
| Subtotal (manual) | $39,140 | ||
Now apply the experience mod. At a clean 0.85 mod, that's roughly $33,300. At a claims-driven 1.25 mod, the same payroll costs about $48,900 — a swing of more than $15,000 a year on identical crews. And note what happens if the contractor hires an uninsured subcontractor: at audit that sub's payroll gets added at the 5403 rate, quietly inflating the bill. (Rates here are illustrative to show the mechanics, not a quote — your real class-code rates depend on NCCI loss costs and the carrier's filed multiplier.)
The surprise most specific to contractor comp is subcontractors. At audit, any subcontractor who cannot produce a valid certificate of workers' comp insurance is generally treated as your employee, and their entire payroll is added to your premium at your trade rate. For a general contractor running multiple subs on a job, that can be the largest and most avoidable audit charge of the year. The fix is discipline, not money: collect a current comp certificate from every sub before they start work, and keep the file. An uninsured sub is a premium liability the moment they step on your site.
Mississippi is an NCCI state. The National Council on Compensation Insurance files advisory loss costs by class code, and each carrier files and applies its own loss cost multiplier and appetite on top. Contractor appetite varies more than almost any other segment — a carrier that likes finish carpentry may want nothing to do with roofing, structural steel, or high-work. That means the multiplier and the appetite together can move the same contractor's premium substantially between carriers. Shopping the account across contractor-friendly markets is exactly where an independent agency earns its keep.
Mississippi generally requires employers with five or more employees to carry workers' comp, and part-time and seasonal staff count toward the threshold. Many small trades contractors sit right at that line. But the statute isn't the whole story: on nearly any commercial or public job, the general contractor and the project owner will require every subcontractor to carry comp before they can work — so in practice a contractor who wants steady work usually needs a policy well before the state forces the issue. Confirm current rules with the Mississippi Workers' Compensation Commission.

The goal isn't just the lowest number — it's a program that gets bound, audited fairly, and won't be non-renewed next year. A rock-bottom quote built on the wrong trade class, or on subs whose certificates were never collected, can turn into an ugly audit bill and a mid-year non-renewal. The right question is "which carrier wants my trade, at a classification and payroll basis that hold up at audit" — and answering it, alongside the general liability, inland marine, and commercial auto your crews also need, is exactly what an independent agency is for.

Contracting rates are on the higher end, so a small clean-record trades contractor might pay from the high single-digit thousands a year; a roofer, larger GC, or high-mod operation can run into the tens of thousands.
It depends on the trade — common ones are 5645/5403 (carpentry), 5551 (roofing), 5190 (electrical), 5183 (plumbing), 5474 (painting), and 5022 (masonry). Clerical (8810) and outside sales (8742) are standard exceptions rated separately.
At audit, an uninsured sub is generally treated as your employee and their payroll is added to your premium at your trade rate. Collect a valid comp certificate from every sub before they start work.
Generally for employers with five or more employees, and part-time and seasonal staff count. Even below that, GCs and owners usually require subs to carry comp before working a job.
No. Comp covers employee injuries only. Third-party damage is general liability, tool and equipment loss is inland marine, and your trucks are commercial auto. A contractor needs all of them.
Confirm the governing trade class, collect every sub's comp certificate, break out overtime, split clerical and sales payroll, manage the mod, document jobsite safety, and shop the account across contractor-appetite carriers.
