Tennessee contractor workers' comp is priced by one formula: (payroll ÷ 100) × class-code rate × experience mod. The number swings enormously by trade — a finish carpenter and a roofer are not in the same universe. In 2026 a small, clean-record contractor might pay a few thousand dollars a year, while a larger contractor running high-hazard payroll with a rough claims history can pay tens of thousands to well over $100,000. Your trade class code and payroll set the ballpark — and in construction, two things move it more than anywhere else: Tennessee's stricter construction rule, and how you handle subcontractors.
Every workers' comp premium starts the same way. Take your annual payroll, divide by 100, multiply by the rate for your class code, then multiply by your experience modification factor. Construction trades are rated across an enormous range because injury severity varies so much: a fall from a roof, a trench collapse, and a paper cut in the office are not the same risk, and the rates reflect it. That's why "what does workers' comp cost" for a contractor always comes back to what trade your crews actually perform and what your claims history looks like.
There is no single "contractor" code. Each trade carries its own, and the spread is dramatic:
One of the most common overpayments in contractor comp is office and estimating payroll rated at the field-trade rate. Getting your bookkeeper and your estimator out of the roofing or excavation code and into their correct clerical or supervisory codes can save real money every year — but only when the payroll records support the split.
Here's the difference that catches contractors off guard. Tennessee generally requires most non-construction employers to carry workers' comp only once they hit five or more employees. Construction is different. Construction-industry employers in Tennessee are generally required to carry coverage with as few as one employee, and the state runs a Construction Services Provider exemption registry for certain qualifying owners who want to be exempted from their own coverage. This is the single biggest structural difference between contractor comp and every other industry in the state — the "I only have a couple guys" logic that works for a retail shop does not work in construction.
Nothing produces a bigger audit surprise for a contractor than uninsured subcontractors. If a sub can't show a valid certificate of workers' compensation insurance, an auditor can add that sub's payroll to your policy at year-end and charge you premium for it. A contractor who "saved money" by using cheaper uninsured subs all year can face a five-figure charge at audit for exactly that payroll. The fix is boring and it works: collect a current certificate of insurance from every subcontractor before they start, keep it on file, and re-collect when it expires.
Tennessee is a loss-cost state. The National Council on Compensation Insurance (NCCI) files advisory loss costs by class code, and each carrier applies its own loss cost multiplier and appetite on top. The practical effect: two carriers can quote the same Tennessee contractor meaningfully different premiums for identical payroll and class codes, because their multipliers and their willingness to write your specific trade differ. Roofing and other high-hazard trades are classes many carriers surcharge or decline, so matching the account to a carrier that genuinely wants the trade is a large part of the result.
Underwriters and auditors price to what you can document. The highest-leverage moves for a contractor:
The goal isn't just the lowest number — it's a program that gets bound, audited fairly, survives the subcontractor question, and won't be non-renewed next year. A rock-bottom quote from a carrier with no real appetite for your trade can evaporate at renewal or blow up at audit when uninsured-sub payroll gets charged back. The right question is "which carrier genuinely wants my construction operation, at a mod and classification and sub structure that hold up at audit" — and answering it is what an independent agency is for.

Construction is held to a stricter standard than other industries — generally required with as few as one employee, with a Construction Services Provider exemption registry for certain owners. Don't assume the five-employee rule applies. Confirm with the Tennessee Bureau of Workers' Compensation.
Each trade has its own — roofing and structural steel are among the highest, finish trades among the lowest, clerical and supervisory payroll lower still. Correct classification of each payroll bucket is a major cost lever.
If a sub can't show a valid workers' comp certificate, an auditor can add their payroll to your policy and charge you at audit. Collect a current COI from every sub before they start.
Tennessee is a loss-cost state — NCCI files advisory loss costs and each carrier applies its own multiplier and appetite. High-hazard trades are surcharged by many carriers, so shopping trade-friendly carriers matters.
Fix clerical/supervisory classifications, collect sub certificates before audit, manage the experience mod, and place with a carrier that wants your trade. Classification and audit prevention usually beat chasing the rate.
