Unfunded fringe benefit plans under Davis-Bacon let a contractor pay the fringe portion of prevailing wages directly out of company general assets instead of through an insurance policy or trust — but only if the Department of Labor approves the plan in advance and five specific regulatory conditions are met. Because no money sits in a separate account protecting workers if the business runs into trouble, the DOL treats this route as a privilege rather than a default, and the advance-approval step is what sets it apart from every other fringe benefit arrangement in the construction industry.
The Five Conditions Your Plan Must Meet
Under 29 CFR § 5.28, an unfunded program is not a bona fide fringe benefit unless every one of the following is true at the same time:1eCFR. 29 CFR 5.28 – Unfunded Plans
- The benefits can reasonably be anticipated to be provided. A vague promise or a discretionary perk the company can withdraw at will does not qualify.
- The commitment is legally enforceable by the worker, not just an informal policy.
- The plan is financially responsible — the company can show it has the resources to pay benefits as they come due.
- Every affected laborer and mechanic receives the plan’s terms in writing, typically through a handbook, benefit summary, or formal plan document.
- The Secretary of Labor has approved the plan.
Missing any one of these means the arrangement is not bona fide. Any credit you took against prevailing wages under it is treated as an underpayment.
Actuarial Soundness and Forced Set-Asides
The “reasonably anticipated” test carries more weight than the plain language suggests. The regulation specifically requires that an unfunded plan be able to withstand a test of actuarial soundness, so a program that looks adequate today but cannot realistically cover future payouts fails regardless of current cash on hand.1eCFR. 29 CFR 5.28 – Unfunded Plans
If the Secretary has concerns about a contractor’s ability to meet future obligations, the regulations authorize the Secretary to require the contractor to set aside assets in a dedicated account. Those assets must be sufficient under sound actuarial principles to cover future benefit obligations and must be preserved for that purpose. At that point the “unfunded” plan starts to look a lot like a funded one, which is the intended effect. The set-aside is the backstop that keeps the unfunded route from becoming a way to slip under the prevailing wage floor.
Which Benefits Can Be Provided This Way
The Davis-Bacon Act recognizes a specific list of fringe benefits, and only these can be delivered through an unfunded arrangement:
- Medical or hospital care, and insurance to provide it
- Pension benefits payable on retirement or death
- Life, disability, sickness, accident, and unemployment insurance
- Vacation pay and holiday pay
- Costs of apprenticeship or similar training programs
- Other bona fide benefits, but only where the contractor is not already required to provide them by another federal, state, or local law
That last limit is where contractors most often get caught. Workers’ compensation is required by state law in nearly every state, so paying premiums generates no Davis-Bacon fringe benefit credit. Travel, subsistence, and industry-promotion fund payments generally do not qualify either.2eCFR. 29 CFR 5.29 – Bona Fide Fringe Benefits Vacation and sick leave are the most common unfunded arrangements in the industry because they are simple to run out of general assets without a third-party trust.3U.S. Department of Labor. Fact Sheet 66E – DBRA Compliance With Fringe Benefit Requirements
How to Get DOL Approval
You submit a written request to the Department of Labor demonstrating that the plan is bona fide, meets all five conditions, and is otherwise consistent with the Act. A letter that simply asserts compliance will not do; the Secretary needs enough documentation to evaluate each criterion.1eCFR. 29 CFR 5.28 – Unfunded Plans
What to Include
The regulation does not prescribe a rigid checklist, but a strong submission addresses each qualifying criterion directly. Include the complete written plan document that will be distributed to employees. Provide evidence that the benefit commitment is legally enforceable, such as binding plan language or employment contract provisions. Attach financial records showing you can absorb future payouts — balance sheets, profit-and-loss statements, and cash flow projections all serve this purpose. If the plan is already in operation, records of past payouts strengthen the case.
Identify the classes of laborers and mechanics covered, the effective dates, and the specific benefits included. If the cost varies from worker to worker, explain how you calculated it. Clear submissions get fewer follow-up requests, and follow-ups are what stall approval.
Where to Send It
The regulation lists three channels: regular mail to the Wage and Hour Division’s Director of the Division of Government Contracts Enforcement in Washington, DC; email to unfunded@dol.gov; or any other method the Administrator directs.1eCFR. 29 CFR 5.28 – Unfunded Plans Email is the newer option and generally the fastest. Whatever channel you use, the process ends with a formal determination letter approving or denying the plan. Keep that letter permanently. You will need to produce it during any future payroll audit on a covered project.
Calculating Your Hourly Credit
Approval is only the start. The credit you take against prevailing wages is not dollar-for-dollar against project spending. You have to annualize the cost so federal work does not absorb an outsized share of the expense.
The formula: take the total annual cost of providing the benefit to an individual worker and divide it by the total hours that worker spent on all jobs during the same period — both Davis-Bacon and private work. The quotient is your per-hour credit.4eCFR. 29 CFR 5.25 – Rate of Contribution or Cost for Fringe Benefits
Everything turns on that denominator. If a worker logs 1,200 hours on federal projects and 600 hours on private jobs, you divide by 1,800. Dividing by only the federal hours inflates the credit and is a violation. If benefit costs differ across workers, you calculate the credit separately for each; you cannot use a blended rate.
The regulation permits annualization over a shorter period when the cost is attributable to less than a full year, which helps if you launch a plan mid-year or if costs shift seasonally.4eCFR. 29 CFR 5.25 – Rate of Contribution or Cost for Fringe Benefits The all-hours-in-the-denominator rule still applies within the shorter window.
Administrative Costs Do Not Count
Your own overhead for running the plan is not a creditable benefit cost. Time your office staff spends processing claims, tracking invoices, updating personnel records, mailing tax documents, and handling Davis-Bacon recordkeeping is treated as an ordinary business expense.5eCFR. 29 CFR Part 5 Subpart B – Interpretation of the Fringe Benefits Provisions of the Davis-Bacon Act The only administrative costs that can count are those incurred by a third-party administrator, insurance carrier, or trust fund and directly tied to delivering actual benefits, such as claims review and referral authorization. Paying a third party to handle work that would otherwise be your own overhead does not convert it into a creditable cost.
What Happens If You Get It Wrong
Enforcement on the fringe benefit side of Davis-Bacon has real teeth, and none of the penalties require a finding of intent.
Back Wages Plus Interest
If prevailing wages or fringe benefits come up short, you owe the full difference to every affected worker. On top of that, the DOL charges daily compounding interest at the rate set under 26 U.S.C. § 6621 for tax underpayments.6eCFR. 29 CFR Part 5 – Labor Standards Provisions Applicable to Contracts Covering Federally Financed and Assisted Construction On a large crew, the interest number alone can climb quickly.
Withholding of Contract Payments
The contracting agency can withhold from your contract payments an amount sufficient to cover unpaid wages and any liquidated damages.7U.S. Department of Labor. Fact Sheet 66 – The Davis-Bacon and Related Acts (DBRA) The money is held back before it reaches you, and it stays there until the dispute is resolved. On tight margins, that alone can strain other projects.
Debarment
The most serious sanction is debarment. A contractor or subcontractor found to have disregarded its obligations to workers can be barred from any federal or District of Columbia contract for three years.8Office of the Law Revision Counsel. 40 USC 3144 – Authority of Comptroller General The bar reaches responsible officers and any firm in which those individuals have an interest.9eCFR. 29 CFR 5.12 – Debarment Proceedings For a contractor whose pipeline is federal work, three years off the list is often fatal.
The DOL surfaces these problems through routine payroll audits on covered projects. Claiming credit for a plan that was never approved, miscalculating the annualized rate, or failing to keep adequate records is enough to trigger action, and the burden of producing documentation sits with you.
