The running log that keeps every worker’s wage-determination fringe rate, annualized hourly credit, plan facts, and cash in lieu in one place, so the fringe credit holds up instead of turning into back-wage liability.
Why this exists
The Davis-Bacon prevailing wage is two numbers, not one. There is the basic hourly rate, and there is the fringe rate, and the wage determination publishes them side by side for a reason: the contractor owes the sum. You can pay the whole thing in cash, you can pay part of it as bona fide fringe benefits, or you can pay any combination of the two, but the total has to land. Most firms understand the basic rate cold. The fringe side is where the money quietly leaks, because fringe credit is not the premium you wrote a check for. It is a rate per hour, annualized across every hour the worker put in, and the arithmetic almost never matches the intuition.
Here is the trap that catches good contractors. A firm pays a health premium of, say, a few hundred dollars a month for a field employee and assumes that covers the fringe obligation on the federal job. But the credit is not the monthly premium. It is the cost divided by the total hours the worker actually worked, on both private and federally covered work, over the period the cost covers. A worker who logs heavy private-side hours and only a slice of Davis-Bacon hours generates a much smaller per-hour fringe credit than the raw premium suggests, and the gap between the credit the firm thinks it has and the credit it can actually defend becomes back-wage liability across every covered hour. The Wage and Hour Division calls failing to annualize, or annualizing incorrectly, one of the most common fringe-benefit violations it finds.
The reason this happens is that the proof is scattered and nobody owns the per-hour math. The premium invoice sits with accounting. The hours sit in payroll. The plan document that says whether the benefit is funded or unfunded, vested or forfeitable, sits in a benefits binder. Whether a given worker is even eligible to participate sits in an HR file. And the cash-in-lieu amount that should appear on the WH-347 sits in whatever the payroll clerk remembered to enter. When an investigator asks the firm to show the hourly fringe credit it took for one worker on one classification, the answer requires pulling four documents and doing a division that was never written down.
This log pulls the fringe story for each worker into one row. It captures the wage-determination fringe rate the firm is trying to meet, the bona fide benefits and their annualized hourly credit, the cash paid in lieu, and the eligibility and plan facts that decide whether the credit holds up. It does not approve your unfunded plan or compute your annualization for your specific census; the wage determination, the plan terms, and a Wage and Hour Division approval where one is required all govern that. What it gives you is the structure to show, per worker and per classification, that the basic rate plus the creditable fringe plus any cash in lieu meets the prevailing wage the determination requires, and that you can prove it line by line.
Who uses this
- Federal general contractors and primes on Davis-Bacon or Davis-Bacon Related Act work who pay part of the prevailing wage as fringe benefits and have to defend the hourly credit they took for every classification
- 8(a) and small-business subcontractors running federal crews, where one un-annualized health premium quietly underpays the fringe obligation across hundreds of covered hours
- Payroll and compliance administrators who fill out the WH-347 each week and need the cash-in-lieu and fringe figures to tie to documented, annualized credit rather than to a monthly premium
- Controllers and benefits administrators who have to confirm a plan is funded and paid irrevocably to a third party, or that an unfunded plan meets the criteria and any required approval, before its cost is credited
- CFOs and owners signing the weekly certification, who carry personal exposure when the fringe credit on the payroll cannot be reconstructed from the plan documents and the hours
The 15-column fringe benefits documentation log
This log captures 15 columns for every worker whose prevailing wage is met in whole or in part with fringe benefits on a Davis-Bacon covered project. Open a row per worker per classification, fill the wage-determination and plan columns once, and update the hours and credit columns each pay period. The columns are ordered around the four questions an investigator asks about fringe: what was owed, what was credited, how the per-hour credit was computed, and whether the plan and the worker actually qualified for it.
- Worker name and identifying number. The worker’s name and the individual identifying number used on certified payroll, which under the current convention is the last four digits of the Social Security number rather than the full nine. One row per worker per classification so the fringe credit stays tied to a single person and a single rate. The common slip is tracking fringe at the company level and never proving it per worker, which is exactly the granularity an investigator demands when they pick one name off the payroll.
- Classification and applicable wage determination. The Davis-Bacon classification the worker performs and the wage determination number and date that governs the rate. The fringe obligation is published per classification, so the credit has to be measured against the right line on the right determination. The mistake is recording a loose trade name or an outdated determination, which leaves you defending a fringe credit against the wrong target number.
- Wage-determination fringe rate (the obligation). The hourly fringe amount the applicable wage determination sets for this classification, which is the figure the worker’s bona fide benefits and any cash in lieu must add up to. The Davis-Bacon prevailing wage is the basic hourly rate plus this fringe rate, and the two are interchangeable only in the sense that you may shift the fringe portion to cash, not reduce it. The error is reading only the basic rate off the determination and treating fringe as optional, when the sum of both is what is owed.
- Bona fide fringe benefits provided. The specific benefits the firm provides toward the fringe obligation, such as health insurance, a pension or retirement contribution, life insurance, vacation, holiday, or sick leave. Only bona fide benefits count; the Department recognizes categories like life insurance, health insurance, pension, vacation, holidays, and sick leave. The slip is listing a benefit that is really a legal obligation or a normal cost of doing business, or one the worker does not actually receive, and assuming it lowers the cash the firm owes.
- Funded or unfunded plan. Whether each benefit is delivered through a funded plan, where the contractor pays a trustee or third party, or an unfunded plan, where the contractor funds the benefit from general assets. The distinction drives the proof you need: a contribution irrevocably made to a trustee or third party under a bona fide plan can be credited without prior Department approval, while an unfunded plan must clear additional criteria. The mistake is treating a benefit paid out of general cash flow as if it were a funded plan, with none of the unfunded-plan safeguards in place.
- Funded-plan contribution detail. For funded benefits, the payee trustee or third party, the contribution amount, and the contribution frequency, which must be made at least quarterly and irrevocably. Contributions to a bona fide fund, plan, or program made irrevocably to a third party are creditable, and forfeited Davis-Bacon contributions may not revert to the contractor. The error is crediting a contribution that the firm can still claw back, or one made too infrequently to count, because a revocable or sporadic contribution is not the irrevocable periodic payment the rule requires.
- Unfunded-plan criteria and approval. For unfunded benefits, confirmation that the plan can be reasonably anticipated to provide the benefit, represents a legally enforceable commitment, is carried out under a financially responsible program, has been communicated in writing to the affected workers, and that the contractor has requested and received Wage and Hour Division approval. To show financial responsibility, the Department generally requires the contractor to set aside or separately account for sufficient funds at least quarterly. The mistake is crediting reasonably anticipated costs of an unfunded benefit with no written communication, no set-aside, and no approval, which leaves the credit unsupported.
- Total benefit cost for the period. The total cost the firm incurred for the worker’s bona fide benefit over the period the cost covers, before it is converted to an hourly rate. This is the numerator of the annualization, and it must be the cost of the benefit itself, not the firm’s expenses in administering it. A contractor’s own administrative expenses in providing fringe benefits, including amounts paid to a third party to perform those tasks, are not creditable. The slip is folding claim processing, invoice tracking, or recordkeeping costs into the benefit cost and crediting them as fringe.
- Total hours worked in the period (private plus DBRA). The total hours the worker worked during the period the cost is attributable to, counting both private, non-covered work and Davis-Bacon covered work. This is the denominator of the annualization, and leaving private hours out is the single most common way firms overstate the fringe credit. To annualize, the total benefit cost is divided by the total hours worked on both private and DBRA-covered work during the period. The mistake is dividing the cost only by covered hours, which inflates the per-hour credit and underpays the worker on the federal job.
- Annualized hourly fringe credit. The benefit cost from column 8 divided by the total hours from column 9, giving the hourly rate of contribution the firm may credit toward the fringe obligation. Where the contribution varies by worker, the credit must be determined separately for the amount contributed on behalf of each worker. There is a recognized exception worth noting: contributions to a defined-contribution pension plan that provides immediate participation and essentially immediate vesting are excepted from annualization. The error is crediting the raw premium or contribution as if it were already an hourly rate rather than running the division.
- Eligibility to participate. Whether this specific worker is actually eligible to participate in each benefit plan credited on their row. A contractor may not take credit for contributions on behalf of workers who are not able to participate in the plan, such as those excluded because of age or part-time status. The mistake is spreading a plan’s total cost across the whole crew, including workers the plan itself excludes, and crediting fringe for people who can never receive the benefit.
- Cash paid in lieu of fringe. The hourly amount, if any, paid to the worker as cash in lieu of fringe benefits, which on the WH-347 is the worker’s covered hours multiplied by the cash-in-lieu hourly rate. The fringe obligation can be met by bona fide benefits, by cash in lieu, or by a combination, so this column plus the creditable benefit credit must together reach the column 3 obligation. The slip is paying cash in lieu but never recording it as such, so the certified payroll cannot show how the fringe portion was satisfied.
- Total fringe satisfied versus obligation. The annualized benefit credit from column 10 plus the cash in lieu from column 12, compared against the wage-determination fringe rate in column 3, with the gap if any. This is the column that proves, per worker, that the fringe portion of the prevailing wage was actually met. The error is a row where the credited benefit plus cash does not reach the determination’s fringe rate, which is an underpayment hiding in plain sight until an investigator runs the same subtraction.
- Supporting documents and location. Where the proof for this row lives: the wage determination, the plan documents or trust agreement, the premium invoices or contribution records, the written communication for an unfunded plan, and any Wage and Hour Division approval. A fringe credit is only as good as the documents behind it, and Davis-Bacon recordkeeping requires the contractor to be able to substantiate the costs and contributions credited. The slip is a log that asserts a credit without naming the document, the trustee, or the approval that backs it.
- Reviewer, date, and status. Who reconciled the fringe credit for this worker, the date they last checked it, and the compliance state of the row, such as fully met by benefits, met by a benefit-plus-cash combination, annualization pending, or short and owed a correction. This is the column the compliance lead scans down before the certified payroll goes out, to see which rows are defensible and which need a recomputed credit, a missing approval, or additional cash in lieu before filing. Notes carry the context an auditor will ask about months later.
How to use it
Set the obligation first. For each worker and classification, pull the wage-determination fringe rate into column 3 and the determination number and date into column 2, so every credit on the row is measured against the right published number. The prevailing wage is the basic rate plus this fringe rate, and your job on this log is to prove the fringe half, since the basic half is straightforward cash.
Then build the credit, and run the annualization rather than trusting the premium. Put the total benefit cost for the period in column 8, the total hours the worker worked across both private and covered work in column 9, and let column 10 carry the division: cost divided by total hours equals the hourly credit. This is the step firms skip, and it is the step investigators check first. Strip out administrative expenses before they touch column 8, confirm in column 11 that the worker is actually eligible for each plan, and record in columns 5 through 7 whether each benefit is a funded plan paid irrevocably to a third party at least quarterly or an unfunded plan that has cleared the criteria, the written communication, the quarterly set-aside, and any required approval.
Close the loop per worker and tie it to the WH-347. Add any cash in lieu in column 12, then let column 13 add the annualized benefit credit to the cash in lieu and compare the total against the obligation in column 3; if the total falls short, the worker is owed the difference and the row gets flagged in column 15 before the payroll is certified. The XLSX version does this arithmetic for you: it annualizes the benefit cost over total hours, sums the benefit credit and cash in lieu, flags any row where the total fringe is below the wage-determination rate or where private hours are missing from the denominator, and rolls the status column into a project-level view so a compliance lead sees every short row at once. The PDF gives you a printable structure with sample rows for a binder or a submittal, and the DOCX is the editable version for firms that keep their compliance records in Word.
Stop reconstructing fringe credit one audit at a time
Every fringe-benefit row on a certified payroll is a quiet bet that the annualized credit, the funded or unfunded plan facts, the eligibility, and the cash in lieu all add up to the wage-determination rate, and that you can prove it for one worker on one classification years after the job closes. Doing that math by hand across a full crew and several jobs is where the misses happen, because the cost, the hours, the plan terms, and the eligibility live in four different systems. Contracts Connected’s Certified Payroll Analyzer reads incoming certified payroll, checks the fringe and cash-in-lieu figures against the applicable wage determination, and flags the rows where the credited fringe falls short, where the math does not tie, or where the support is missing before a report goes to the contracting officer.

Frequently asked questions about the fringe benefits documentation log
What counts as a fringe benefit under Davis-Bacon?
Bona fide fringe benefits are employer-provided benefits the Department recognizes toward the prevailing wage obligation, with common examples including life insurance, health insurance, pension or retirement, vacation, holidays, sick leave, and supplemental unemployment benefits. The benefit has to be genuinely provided to the worker, not a legal obligation the employer already owes or a normal business cost dressed up as a benefit. A contractor’s own administrative expenses in providing the benefits, including amounts paid to a third party to handle claims, invoices, or recordkeeping, are not creditable toward the obligation. When in doubt about whether a particular benefit qualifies, confirm it against Fact Sheet #66E and 29 CFR Part 5, Subpart B.
How do I calculate the hourly fringe credit (annualization)?
You annualize. Divide the total cost of the fringe benefit contribution, or the reasonably anticipated cost for an unfunded plan, by the total number of hours the worker worked on both private, non-covered work and Davis-Bacon covered work during the period the cost is attributable to. The result is the hourly rate of contribution you may credit toward the fringe obligation. If the contribution amount varies by worker, the credit must be determined separately for each worker. Failing to annualize, or annualizing incorrectly by leaving private-project hours out of the denominator, is one of the most common fringe-benefit violations the Wage and Hour Division finds, so confirm your method against 29 CFR 5.25 and Fact Sheet #66E.
Can I just pay cash instead of providing fringe benefits?
Yes. The obligation to pay the prevailing wage can be met by paying the entire amount as cash wages, by providing bona fide fringe benefits, or by any combination of the two. When you pay cash in lieu of fringe benefits, that amount belongs in the cash-in-lieu portion of the certified payroll, generally equal to the worker’s covered hours multiplied by the cash-in-lieu hourly rate. What you cannot do is reduce the total: the basic rate plus the fringe rate on the wage determination is the floor, and shifting the fringe portion to cash changes the form of payment, not the amount. Keep the cash-in-lieu figure documented so the certified payroll shows exactly how the fringe portion was satisfied.
What’s the difference between a funded and an unfunded fringe plan?
A funded plan is one where the contractor pays into the benefit through contributions to a trustee or a third party. Any contribution irrevocably made to a trustee or third party under a bona fide fringe benefit fund, plan, or program can be credited toward the prevailing wage requirement without prior Department approval, and forfeited Davis-Bacon contributions may not revert to the contractor. An unfunded plan is one the contractor funds from its own general assets rather than by paying a third party. An unfunded plan’s reasonably anticipated cost may be creditable only if it meets additional criteria, including written communication to the affected workers and, generally, Department approval, so the two are not interchangeable from a proof standpoint.
What does an unfunded fringe plan have to meet to be creditable?
Under the regulations, no fringe benefit is eligible for consideration as an unfunded plan unless it can be reasonably anticipated to provide the benefit described, represents a commitment that can be legally enforced, is carried out under a financially responsible plan or program, has been communicated in writing to the laborers and mechanics affected, and the contractor has requested and received approval of the plan or program from the Wage and Hour Division. To show the plan is financially responsible, the Department will generally require the contractor to set aside or separately account for sufficient funds to meet future obligations, no less often than quarterly. Document each of those elements on the row so the credit can be supported if it is questioned.
Can I take fringe credit for every worker on the crew?
No. A contractor may not take credit for contributions made on behalf of workers who are not eligible to participate in the fringe benefit plan, such as workers excluded because of age or part-time status. Spreading a plan’s total cost across the entire crew and crediting fringe for workers the plan itself excludes overstates the credit and underpays those workers on the covered job. Determine the credit worker by worker, confirm each worker is actually eligible for each plan you credit on their row, and contributions made for ineligible workers cannot be counted toward the prevailing wage obligation. When eligibility rules are complex, check them against the plan document and Fact Sheet #66E before crediting.
