Prevailing wage in Missouri: Guide for contractors

Overseeing public works projects in Missouri comes with some unique compliance considerations. In addition to the traditional challenges that come with managing a jobsite and meeting budget constraints, contractors also need to adhere to Missouri’s prevailing wage laws, which establish minimum pay for workers on qualifying projects.

In this guide to prevailing wage in Missouri, learn how rates are determined and how contractors can maintain compliance to avoid costly violations.

What is prevailing wage in Missouri?

Prevailing wage refers to the wage rate contractors need to pay employees performing labor on public works projects valued over $75,000. 

There’s no single prevailing wage rate that applies throughout the state. The Missouri Division of Labor Standards releases its Annual Wage Order by July 1st every year. The order establishes rates based on:

• The county where work is taking place
• The trade classification of each worker
• The type of work 

In addition to setting the rates, the Missouri Division of Labor is also responsible for monitoring and enforcing compliance across public projects. But MO prevailing wage laws don’t override or replace federal standards. Projects that receive both federal and state funding need to comply with the Davis-Bacon Act as well as state-specific rules. In practice, this means following whichever rules are stricter. There are no penalties for paying workers more than the required prevailing wage rate.

Who do Missouri’s prevailing wage laws apply to?

There are several types of construction employees that are covered under Missouri’s labor protections. Each has their own prevailing wage rate specific to the work they do.

Skilled tradespeople

Specialized trades are covered on public projects, each with their own specific rates and fringe benefit requirements. Skilled trades include:

• Electricians
• Plumbers 
• Pipefitters
• Ironworkers 
• Roofers
• Operating engineers
• Carpenters 

General construction workers

Missouri’s prevailing wage requirements also protect laborers and other general construction workers. But classifications for general workers are typically based on the tasks and activities they perform, not the job title. This requires contractors to carefully review annual wage orders and assign classifications appropriately using time-tracking data from the field.

Apprentices and entry-level workers

Apprentices and entry-level workers are also covered by Missouri’s prevailing wage laws if they work under a federally registered apprenticeship program. However, both apprentices and entry-level workers typically receive a reduced rate of 50% of the journeyman rate, which includes fringe benefits. The Missouri Division of Labor Standards also establishes a maximum ratio of one apprentice for every journeyman on the site.

How to figure out which prevailing wage rates apply to a Missouri project

Several factors impact how much prevailing wage is in Missouri. Since there’s no statewide rate, contractors need to first determine if their project is covered and carefully assign the correct rate to each worker. 

Where to find the rate

Applicable prevailing rates should be clear in the bid specifications, but contractors should still track prevailing wage rates directly in the Missouri Division of Labor Standards’ Annual Wage Order. This updates every year on July 1st and allows construction employers to look up determinations by county.

County-based wage determinations

Prevailing rates typically reflect the specific market conditions and collective bargaining agreements in each location. So, a pipefitter may have a very different rate in St. Louis County versus Lafayette County.

Since many firms oversee multiple projects at one time, contractors must carefully track where each employee is working and which rate to apply.

Trade and worker classifications

Worker classifications also directly influence wage rates. Even if they work in the same geographical location, an electrician may have a completely different rate than a carpenter or general laborer. 

The type of work is also relevant when determining the correct prevailing wage. For example, Missouri distinguishes between building construction and heavy/highway construction, so one worker’s rate may change depending on the type of work they perform. Compliance requires highly accurate time tracking so that each hour’s rates are tied to the correct worker, task, and jurisdiction.

Combined wage and fringe benefit calculations

Prevailing wage laws regulate both hourly rates and fringe benefit payments. Under both federal and Missouri law, employers can provide fringes in the form of bona fide benefits packages or equivalent cash sums. Qualifying employer-provided benefits include:

• Health, dental, and vision insurance
• Retirement contributions
• Paid time off

Missouri often lists wage and fringe benefit requirements as a combined total. Not having the exact fringe benefit cost listed may make determining a qualifying bona fide package plan more difficult. 

Public Works Contracting Minimum Wage 

The Public Works Contracting Minimum Wage (PWCMW) is a localized wage rate the Division of Labor Standards may use instead of the standard prevailing wage when they lack sufficient wage data for a particular job title. This specialized rate applies when there are fewer than 1,000 reported hours in the county for an occupation.

PWCMW is calculated by multiplying the average wage rate in the county by 120%. This process makes sure workers on public projects still get paid an appropriate wage regardless of statistical limitations.

Compliance, penalties, and violations

Prevailing wage violations often come down to a lack of operational consistency rather than an intentional decision on the part of payroll teams. Disconnect between the office and field, fragmented payroll systems, and poor time tracking are some of the most frequent causes of violations.

Common prevailing wage compliance risks include:

• Failure to pay the correct rate: Underpaying workers can lead to back wages, financial penalties, and civil action.
• Worker misclassification: Misclassifying a worker can quickly lead to underpayment and create payroll inconsistencies, even if hours are recorded correctly.
• Inaccurate or incomplete payroll records: Not maintaining clear documentation of employee classifications, hours worked, and rates paid can leave firms vulnerable in the event of a dispute or audit.
• Failure to maintain certified payroll documentation: Public projects often come with specific certified payroll reporting requirements, and failing to meet them can trigger audits and reviews.
• Subcontractor non-compliance: The contract-holding construction company can face consequences if subcontractors fail to comply with prevailing wage obligations.
• Failure to apply overtime and fringe rules: Under RSMo 290.230 and the Division of Labor Standards, employers must pay 1.5x the prevailing wage for hours beyond 10 in a day or 40 in a week, and 2x the rate for any work on Sundays and holidays.
• Withheld payments and contract disputes: When a violation occurs during the course of an active project, relevant public agencies may have the authority to withhold or delay contract payments.
• Debarment and reputational consequences: Intentional violations and repeated infractions can seriously damage a firm’s reputation. This impacts their relationships with owners and business partners and may even disqualify them for future public projects.

Maintaining standardized systems and processes can help contractors avoid preventable mistakes and the costly penalties that follow.

Missouri prevailing wage exceptions

Most public works projects are covered under Missouri’s prevailing wage laws, but there are some specific scenarios where they may not apply.

Projects that fall below the monetary threshold

Prevailing wage in Missouri is only required on projects that cost at least $75,000. If the value of a contract falls below this threshold, then the contractor likely doesn’t need to follow standard prevailing rates.

Certain maintenance, emergency, or exempt work

Some routine maintenance and emergency repairs aren’t part of prevailing wage coverage, along with certain material supply contracts. It’s the contractor’s responsibility to determine when prevailing wage applies and how to administer it appropriately, so it’s always a good idea to seek clarification from Missouri’s governing body.

Supervisory and other non-covered roles

Prevailing wage typically only applies to workers performing tasks on the jobsite. Even if the project qualifies under Missouri standards, some supervisors and off-site personnel may not be covered. Since many workers wear multiple hats on jobsites, like a supervisor helping out with a concrete pour, payroll teams need to carefully track hours by work activity, not just occupational title.
