Davis-Bacon Fringe Benefits: What Contractors Need to Know to Stay Compliant

Key Takeaways

• The Davis-Bacon and Related Acts (DBRA) require contractors on federally funded projects to pay prevailing wages, including a basic hourly rate (BHR) and fringe benefits.
• Contractors can meet their fringe benefit obligation through cash wages, bona fide benefit plans, or a combination of both.
• Fringe benefits must be “bona fide,” meaning they need to follow ERISA, IRS, and applicable state insurance law requirements.
• Funded plans (insurance, trusts) can be credited without prior Department of Labor approval. Unfunded plans (vacation, sick leave) require written DOL approval before use.
• Annualization is a required calculation method that spreads fringe benefit costs across all hours worked, not just DBRA project hours.
• State prevailing wage laws are typically stricter than federal DBRA rules. If a project is both state and federally funded, both sets of rules apply.
• Common violations include misclassifying workers, skipping DOL approval for unfunded plans, miscalculating annualization, and improperly crediting administrative expenses as fringe benefits.
• The financial consequences of non-compliance are serious. One contractor in California had to repay $220,000 in vacation and holiday pay, plus penalties and fines.

What the Davis-Bacon Act Requires

The Davis-Bacon and Related Acts (DBRA) apply to contractors and subcontractors working on federally funded or federally assisted construction projects. The law requires that workers classified as laborers and mechanics be paid at least the prevailing wage rate established for the area where the work is performed.

That prevailing wage is not just a base pay number. It is the combination of two components:

1. The Basic Hourly Rate (BHR)
2. Fringe benefits

Both must be paid for all hours worked on the job site. If a contractor does not provide bona fide fringe benefits, they must pay the full prevailing wage, including the fringe benefit portion, entirely in cash.

Here is a straightforward example of how this works in practice:

• Basic hourly rate: $27.00
• Fringe benefits: $14.00
• Total prevailing wage obligation: $41.00

A contractor can satisfy this obligation in several ways:

• Pay $41.00 entirely in cash wages.
• Pay $27.00 in cash plus $14.00 in qualifying fringe benefits.
• Pay $35.00 in cash plus $6.00 in qualifying fringe benefits.

The flexibility exists, but the total must always meet or exceed the prevailing wage rate listed in the wage determination.

What Counts as a Bona Fide Fringe Benefit

Not every benefit a contractor provides qualifies for DBRA credit. The Department of Labor has specific standards that define what constitutes a bona fide fringe benefit.

Benefits that are generally accepted as bona fide include:

• Medical and health care
• Dental and vision insurance
• Life insurance
• Certain workers' compensation benefits that exceed legally required coverage may qualify, but workers' compensation required by federal, state, or local law is not creditable toward Davis-Bacon fringe benefit obligations.
• Pension and retirement contributions
• Vacation and holiday pay (under specific conditions)
• Apprenticeship programs registered with the DOL

To qualify, the benefit must be provided under a legally enforceable plan, fund, or program. That plan must also meet applicable ERISA, IRS, and state insurance requirements.

What does not qualify for DBRA credit:

• A contractor's internal administrative costs generally are not creditable. However, certain reasonable administrative expenses incurred by third-party benefit providers, insurers, or trust funds may be included as part of a bona fide fringe benefit plan.
• Benefits required by other federal, state, or local law, such as workers’ compensation insurance under a compulsory state statute
• Transportation, board, lodging, or other facilities provided for the contractor’s convenience
• Travel pay, per diem, or lodging expenses
• Cell phone or vehicle allowances
• Holidays that are already accounted for in the wage determination

A contractor cannot double-count. If a benefit is required by law, it cannot also be counted as a DBRA fringe benefit credit.

Funded Plans vs. Unfunded Plans

This is one of the areas where contractors most commonly run into problems. The distinction between funded and unfunded plans matters because the compliance requirements are very different.

Funded Plans

A funded plan is one where contributions are made to an independent third party, such as an insurance carrier or a trust fund. The contractor makes irrevocable contributions on behalf of workers, and those funds cannot be recaptured or redirected back to the contractor.

Key requirements for funded plans:

• Contributions must go to a trustee or third party not affiliated with the contractor.
• The trust or fund must not allow the contractor to get the money back.
• Contributions must be made at least quarterly.
• The trustee must meet standard fiduciary obligations.

Funded plans include common arrangements like group health insurance, union pension funds, and 401(k) plans. Contractors can take credit for contributions to these plans without getting prior approval from the Department of Labor.

Unfunded Plans

‍

An unfunded plan is funded from the contractor’s own general assets rather than a separate fund or trust. Vacation and sick leave plans are the most common examples in the construction industry. The money stays in the company’s accounts until the benefit is paid out.

Unfunded plans can be credited toward prevailing wage obligations, but only if all of the following conditions are met:

• The plan has been communicated to employees in writing.
• The cost reasonably anticipates the cost of providing the actual benefit.
• The plan represents an enforceable commitment to provide benefits.
• The plan is carried out under a financially responsible program.
• The contractor sets aside sufficient funds to ensure benefits will be available when workers become eligible.

Most critically, contractors with unfunded plans must obtain prior written approval from the Department of Labor before they can claim credit. This is not optional.

To request approval, submit a written request to:

Email: unfunded@dol.gov
Mail: United States Department of Labor, Wage and Hour Division, Director, Division of Government Contracts Enforcement, 200 Constitution Ave., NW, Room S-3502
Washington, DC 20210

Skipping this step is a common and costly mistake. A contractor who attempts to take credit for an unfunded vacation or holiday plan without DOL approval is not compliant, regardless of how well the internal plan is structured.

Eligibility and Participation Rules

A contractor cannot claim fringe benefit credit for every worker just because a plan exists. Who is actually covered matters.

Contractors may take credit for contributions made on behalf of workers who are likely to become plan participants, even if they are not yet eligible. For example, if a health insurance plan has a 30-day waiting period for new hires, contributions during that waiting period can still be credited.

However, contractors cannot take credit for contributions made on behalf of workers who are explicitly excluded from the plan, such as part-time employees or workers excluded based on age.

If a worker is not eligible to participate, the contractor cannot count that worker’s fringe benefit contribution toward its prevailing wage obligation.

The Annualization Requirement

Annualization is one of the most misunderstood parts of DBRA fringe benefit compliance, and getting it wrong is one of the most common violations.

The concept: DBRA credit for fringe benefit contributions is based on the effective annual rate of contributions averaged over all hours worked by that individual during the year, including both DBRA project hours and non-DBRA hours.

Why this matters: Fringe benefits like health insurance or pension contributions generally cover a worker for the entire year, whether they are working on a prevailing wage job or not. The annualization rule prevents contractors from loading all the cost of a year-round benefit onto Davis-Bacon project hours, which would inflate the apparent hourly credit beyond what the benefit actually costs per hour worked.

To annualize correctly, a contractor divides the total annual cost of the benefit by the total number of hours the worker worked across all projects during the year. The resulting figure is the creditable hourly rate.

There are limited exceptions to the annualization requirement. Defined contribution pension plans that meet all of the following conditions do not require annualization:

• The plan is not continuous in nature (not available without penalty throughout the year)
• The benefit does not cover both DBRA and non-DBRA work.
• The plan provides immediate participation and essentially immediate vesting (within the first 500 hours worked)

For any other exception, a contractor must submit a written request to the Wage and Hour Division explaining why the plan should be exempt.

For apprenticeship programs, annualization works slightly differently.

The total cost of the program is divided by the total hours worked by all of the contractor’s workers in that classification across both covered and non-covered projects. The credit can only be claimed against prevailing wage obligations for workers in the same classification as the apprenticeship.

Fringe Benefits for Apprentices

Apprentices are generally paid in accordance with the provisions of their approved apprenticeship program. If the apprenticeship program specifies a fringe benefit rate, that rate applies, but only when apprentices are employed in accordance with the program’s journeyworker-to-apprentice ratio.

If the apprenticeship program does not address fringe benefits, apprentices must receive the full fringe benefit amount listed in the wage determination for the journeyworker classification under which they are training.

Contractors may only take credit for costs associated with apprenticeship programs that are registered with the DOL’s Employment and Training Administration, Office of Apprenticeship, or with a state agency recognized by that office. Voluntary contributions beyond actual program costs do not qualify for credit.

State Prevailing Wage Laws and “Little Davis-Bacon”

Federal DBRA rules set the floor, not the ceiling. Most states have their own prevailing wage laws, often called “little Davis-Bacon” laws, that mirror the federal structure but with additional requirements.

Many state prevailing wage laws impose additional requirements beyond federal Davis-Bacon rules, though requirements vary significantly by state. They may have broader coverage thresholds, shorter contribution deadlines, more detailed reporting requirements, or different definitions of what qualifies as a bona fide fringe benefit.

When a project receives both state and federal funding, both sets of rules apply simultaneously. Contractors on projects with both federal and state prevailing wage requirements should carefully review both sets of requirements and comply with whichever governs the specific issue, often resulting in the application of the more protective standard.

This applies directly to how unfunded plans are handled at the state level. State agencies may have their own approval processes separate from the federal DOL, and their requirements may be more demanding. Contractors working on state-funded projects should not assume that federal compliance automatically satisfies state requirements.

Common Violations and Their Consequences

The Department of Labor has identified the most frequent ways contractors fall out of DBRA fringe benefit compliance:

Misclassifying workers. Assigning workers to the wrong classification results in applying the wrong wage determination, potentially underpaying both base wages and fringe benefits.

Skipping DOL approval for unfunded plans. Any contractor taking credit for vacation pay, sick leave, or similar benefits under an unfunded plan without prior DOL approval is non-compliant. This is a straightforward requirement that is frequently overlooked.

Annualizing incorrectly. The most common annualization error is failing to include all hours worked, not just DBRA hours, in the calculation. Using only prevailing wage project hours inflates the apparent hourly credit and overstates compliance.

Relying on CBA rates that are lower than the wage determination. A collective bargaining agreement does not override a wage determination. If the CBA specifies rates below the prevailing wage, the wage determination controls.

Claiming credit for non-creditable expenses. Administrative costs, travel, per diem, lodging, company vehicle allowances, and legally required benefits cannot be counted as fringe benefit credits.

The financial exposure from these violations is significant. Back wages, interest, fines, and potential debarment from future federal contracts are all possible outcomes. In one documented case, a California contractor was required to repay $220,000 in vacation and holiday pay alone, before penalties were added.

What Contractors and Subcontractors Should Do Now

Staying compliant with DBRA fringe benefit requirements is not passive. It requires active tracking, proper plan documentation, and an understanding of what can and cannot be credited.

A practical checklist:

• Confirm that all benefit plans meet the ERISA, IRS, and applicable state law requirements to qualify as bona fide
• If using unfunded plans for vacation, sick leave, or similar benefits, obtain written DOL approval before claiming any credit.
• Calculate annualization using total annual hours worked across all projects, not just prevailing wage hours.
• Verify that workers excluded from benefit plans by eligibility rules are not being counted in fringe benefit credits.
• Review worker classifications against the wage determination before each project starts.
• Do not count administrative expenses as fringe benefit contributions.
• On state-funded projects, check state prevailing wage requirements in addition to federal rules.
• Keep written documentation showing that unfunded plans have been communicated to employees.

Tracking all of this manually across multiple projects and workforces is where errors typically enter the process. The more workers, classifications, and benefit plans involved, the higher the risk of a calculation error resulting in underpayment and liability.
