What comp costs per plumber in Mississippi
The Bureau of Labor Statistics counts 3,360 plumbers, pipefitters, and steamfitters on payrolls in Mississippi (May 2025), the 36th largest workforce among the 50 states and DC. The median wage is $26.67 an hour, 13% below the US median of $30.67.
Plumbers, pipefitters, and steamfitters make up about the same share of Mississippi jobs as they do nationally (location quotient 0.96).
At the US median of $2.25 per $100 of payroll (Mississippi does not publish its figure online), comp on one worker at that wage costs about $0.60 for every hour worked, or $1,248 a year full time. A 2-person crew comes to roughly $2,496 a year in premium before any experience mod.
Because premium is charged on payroll, who you hire moves the bill. Mississippi pay runs from $17.23 an hour at the 10th percentile to $36.29 at the 90th, so the same rate costs $0.39 an hour on a new hire and $0.82 on a senior hand.
Workers comp requirements in Mississippi
- Coverage required: 5+ employees; no construction carve-out
- Owners and sole proprietors: Owners excluded by default; may elect in at a statutory assumed wage
- State fund: Private market (no state fund)
- Waiting period: 5 days; retroactive if disability lasts more than 14 days
- Penalty for going without: Misdemeanor (up to $1,000 and/or a year), plus civil penalties up to $10,000
Mississippi is one of the few states with no construction carve-out, so a one-to-four-employee construction firm is not required to carry coverage.
Mississippi vs neighboring states
- Alabama: about $1.99 per $100 of payroll
Mississippi does not publish its figure, so the first row is the US median. Among neighbors that publish, Alabama is the cheapest for plumbing comp at about $1.99 and Alabama the most expensive at about $1.99 per $100 of payroll.
If your crews work across the line, list those states under item 3.A or 3.C of your policy before the job starts. Rates follow the state where the work is done, not where your office is.
What moves a plumbing comp bill
- Plumbing rates sit in the middle of the construction classes; the swing comes from your experience mod. Trench and excavation injuries are the costly claims, so trench-safety training pays back quickly.
- Some states split residential and commercial plumbing into different classes. If you do both, make sure the payroll for each is recorded so the cheaper work is not rated at the higher class.
- Apprentices carry the same class rate as journeymen, but their lower wages mean less premium per hour. Your payroll mix matters as much as the rate.
- Uninsured subs (excavators, drywall patchers) get added to your payroll at audit unless you collect certificates before they start.
