Missouri prevailing wage rates are the minimum hourly pay, including fringe benefits, that contractors must pay workers on public works projects where the engineer’s estimate or accepted bid exceeds $75,000. The Division of Labor Standards publishes a new rate for every trade in every one of Missouri’s 114 counties and the City of St. Louis each July 1 through the Annual Wage Order.1Missouri Department of Labor and Industrial Relations. Missouri Prevailing Wage Law and Resources Rates differ by county because they are built from what contractors actually report paying workers in that locality.
When the Rates Apply
The rates attach to construction of “public works,” which the statute defines broadly as fixed works built for public use or paid for wholly or in part with public funds.2Missouri Revisor of Statutes. Missouri Code 290.210 – Definitions Roads, bridges, schools, government buildings, and water systems are the typical examples. Drainage and levee district work is specifically excluded.
“Construction” covers more than new builds. It includes reconstruction, improvement, enlargement, alteration, painting and decorating, and major repair.2Missouri Revisor of Statutes. Missouri Code 290.210 – Definitions Routine maintenance is carved out and does not trigger prevailing wage.3Missouri Revisor of Statutes. Missouri Code 290.230 – Prevailing Wage Rates Required on Construction of Public Works The line between “major repair” and “maintenance” is a common source of friction in compliance disputes.
The $75,000 threshold is measured against either the engineer’s estimate or the accepted bid. Anything at or below that figure is exempt.3Missouri Revisor of Statutes. Missouri Code 290.230 – Prevailing Wage Rates Required on Construction of Public Works Everything above it falls under the full prevailing wage framework.
How to Look Up the Rate for Your County and Trade
Current rates are available through the Department of Labor’s online Annual Wage Order look-up, where you select the county from a dropdown.4Department of Labor. Missouri Department of Labor and Industrial Relations – Annual Wage Order Look-Up A carpenter’s rate in St. Louis County will not match the rate in Dunklin County, and that is by design. The Division builds rates from voluntary Contractor’s Wage Surveys in which contractors report what they actually paid on recent projects in each locality.1Missouri Department of Labor and Industrial Relations. Missouri Prevailing Wage Law and Resources
Each posted rate has two parts: a basic hourly wage and a fringe benefit amount for items like health insurance, pension, and vacation. The contractor must pay the total of both. The fringe portion can be satisfied by contributing to a benefit plan, by paying the worker an equivalent cash amount, or by a combination of the two.
Rates reset July 1. If a new Annual Wage Order has been filed but has not yet become final, keep using the prior order until the transition is official.
Classifying Workers Correctly
Rates attach to occupational titles defined in 8 CSR 30-3.060, not to whatever job label the contractor uses on its internal payroll.5Legal Information Institute. Missouri Code of State Regulations 8 CSR 30-3.060 – Occupational Titles of Work Descriptions An operating engineer, a laborer, and an electrician each have different rates, and classification turns on the work actually performed.
The regulation also makes clear that occupational titles are not jurisdictional. A worker is not prohibited from performing tasks that fall under multiple classifications.5Legal Information Institute. Missouri Code of State Regulations 8 CSR 30-3.060 – Occupational Titles of Work Descriptions When one worker does two kinds of work during a shift, the contractor needs to track the hours by task and pay the applicable rate for each. Labeling a skilled tradesperson as a general laborer to reduce pay is exactly the shortcut that triggers an investigation.
Reduced Rates for Apprentices and Entry-Level Workers
Apprentices and entry-level workers are the only categories that can lawfully be paid less than the full journeyman rate. Registered apprentices in programs approved by the U.S. Department of Labor must be paid at least 50 percent of the applicable journeyman rate for their occupational title, including fringe benefits.6Legal Information Institute. Missouri Code of State Regulations 8 CSR 30-3.030 – Apprentices and Entry-Level Workers Workers on federal-aid highway projects can qualify for reduced rates through programs certified by the U.S. Department of Transportation.
Entry-level workers are a separate category: not a journeyman, not in a registered apprenticeship, but participating in on-the-job training provided by the employer.6Legal Information Institute. Missouri Code of State Regulations 8 CSR 30-3.030 – Apprentices and Entry-Level Workers Any worker who fits neither category must be paid the full journeyman rate. Calling someone an “apprentice” to justify a lower rate only works if that person is actually registered in a qualifying program.
Overtime, Sunday, and Holiday Premiums
Prevailing wage has its own premium pay structure. Overtime on a prevailing wage project is paid at one and one-half times the prevailing hourly rate. Work on a Sunday or a recognized holiday is paid at double the prevailing rate.3Missouri Revisor of Statutes. Missouri Code 290.230 – Prevailing Wage Rates Required on Construction of Public Works
Those multipliers apply to the elevated prevailing rate, not to whatever base rate the contractor would otherwise have paid. Sunday work by a skilled trade adds up quickly, and schedules should be built with that math in mind.
Certified Payroll, Posting, and the PW-4 Affidavit
Contractors have to document that every worker received at least the correct rate for the correct classification. Payroll records should capture each worker’s occupational title, hours worked each day, hourly rate paid, and fringe benefit contributions. The public body overseeing the project typically requires certified payroll submissions on a regular schedule so compliance can be monitored as work progresses.7Missouri Department of Transportation. 110.3 Prevailing Wages and Records (Guidance for Sec 110.3)
At the end of the project, the contractor files an Affidavit of Compliance with Prevailing Wage Law on Form PW-4.8Missouri Department of Labor and Industrial Relations. Affidavit of Compliance with Prevailing Wage Law (PW-4) It is a sworn statement that all workers were paid in accordance with the applicable rates, and final payment can be withheld until it is filed.
On-site posting is also mandatory. Every contractor and subcontractor must post a legible statement of all applicable prevailing wage rates in a prominent, easily accessible location at the project site, and the notice has to stay up for the entire duration of the work. Workers should be able to walk up and check that their pay matches the rate the state requires for their trade and county.
Penalties for Underpayment
The core financial penalty is $100 for each worker underpaid, for each calendar day or partial day the underpayment continues. The public body awarding the contract must include the penalty clause in the contract and must withhold from the contractor’s payments any amounts owed as a result of violations.9Missouri Revisor of Statutes. Missouri Code 290.250 – Penalty for Violation of Prevailing Wage Law On a crew of twenty, two weeks of underpayment produces a serious number.
There is a safety valve. If the contractor pays all back wages owed before the Department of Labor files an enforcement action, the $100-per-day penalty is waived.9Missouri Revisor of Statutes. Missouri Code 290.250 – Penalty for Violation of Prevailing Wage Law Contractors who dispute the finding can request arbitration and then have 45 days after the arbitrator’s decision to pay. Miss that window and the Department can pursue full penalties plus enforcement costs.
Repeat and serious violations reach beyond money. Contractors convicted of prevailing wage violations go on a debarment list maintained by the Secretary of State. A first conviction bars the contractor from public works for one year; each subsequent conviction extends the ban to three years. No public body can award a contract to a debarred firm, and the prohibition reaches subcontracting relationships as well.
Willful violations carry criminal exposure. Any contractor, subcontractor, officer, or agent who willfully violates the law faces a fine of up to $500, up to six months of imprisonment, or both, for each day the violation continues.
How a Worker Files an Underpayment Complaint
A worker who believes they were underpaid on a prevailing wage project can file a complaint with the Division of Labor Standards, which investigates all complaints it receives.10Missouri Department of Labor and Industrial Relations. Wages, Hours and Dismissal Rights Investigators calculate the gap between what the worker actually received and what the applicable rate required.
One limit matters: the Division does not have legal authority to force an employer to pay. It can determine the amount owed and pursue the penalty process, but a worker who cannot resolve underpayment administratively may need to go to court. The public body’s duty to withhold contract payments gives the process real leverage, because contractors who want their public contract paid out have reason to settle the wage dispute.
When Federal Davis-Bacon Rates Also Apply
Projects receiving federal funding can trigger a second layer of prevailing wage requirements under the federal Davis-Bacon Act, which applies to federally funded construction contracts over just $2,000.11U.S. Department of Labor. Davis-Bacon and Related Acts On a project using both state and federal money, the contractor must comply with both. Where the federal and state rates for the same classification differ, pay the higher one. Before bidding on a federally assisted Missouri project, review both the Annual Wage Order for the relevant county and the applicable federal wage determination.
