On a Davis-Bacon wage determination the fringe benefit rate is a separate hourly amount owed on top of the base rate, and the two together are the prevailing wage obligation. A contractor may satisfy the fringe obligation by contributing to bona fide benefit plans, by paying the equivalent amount in cash, or by combining the two — but the obligation itself does not go away, and unlike the base rate, fringe is paid at straight time for every hour worked, including overtime hours.
The two halves of a prevailing wage
Every classification line on a determination has two numbers. The base rate is cash wages. The fringe rate is an additional hourly amount for benefits. A determination listing $32.15 base and $14.80 fringe creates a $46.95 hourly obligation, however it is delivered.
This is where most prevailing wage underpayment originates: a contractor pays the base rate correctly, provides no benefits, and pays no cash equivalent. The base rate alone is not compliance.
What counts as a bona fide fringe benefit
- Health, dental, vision and life insurance.
- Pension and retirement plan contributions, including defined contribution plans.
- Vacation and holiday pay.
- Apprenticeship and training program contributions to a bona fide program.
- Disability and supplemental unemployment benefits.
Paying fringe in cash
Paying the fringe amount as additional cash wages is fully permitted and is what most non-union contractors do. It is simple, it is visible on the pay stub, and it removes any argument about whether a plan is bona fide.
The cost is real, though: cash fringe is wages. It is subject to payroll taxes and it enters the regular rate for other purposes, where a contribution to a benefit plan would not. On a large crew that difference is material, which is why contractors with a genuine benefit program usually prefer plan contributions.
Annualisation: the rule that catches people out
A fringe credit is calculated on an annualised basis. If an employer contributes to a plan for all hours an employee works in a year, but only claims the credit against Davis-Bacon hours, the hourly credit is the total annual contribution divided by total annual hours — not divided by the covered hours alone.
Taking a credit computed only over covered hours inflates the apparent hourly benefit and underpays the worker. This is one of the most common findings in fringe benefit investigations, and it is easy to do by accident with an off-the-shelf payroll setup.
Fringe and overtime
Overtime is time and a half on the basic hourly rate. Fringe is not part of the premium base. Fringe is owed at straight time for every hour worked, including the overtime hours.
| Component | Calculation | Amount |
|---|---|---|
| Straight time wages | 40 × $32.15 | $1,286.00 |
| Overtime wages | 8 × $32.15 × 1.5 | $385.80 |
| Fringe (all hours, straight time) | 48 × $14.80 | $710.40 |
| Total obligation | — | $2,382.20 |
When the fringe column is blank
Plenty of determination lines, particularly non-union survey rates, show no fringe amount at all. That is not an omission — it means the prevailing package in that area for that classification was cash wages with no separate benefit component, and the total obligation is the base rate alone.
What to put on the certified payroll
If fringe is paid into plans, tick that box on the Statement of Compliance and show the base rate in the rate column. If fringe is paid in cash, the cash fringe is part of the rate paid and should be reflected as such. If you split between the two, tick the exception box and describe the split.
The failure mode is a mismatch: fringe genuinely paid in cash, but the Statement of Compliance certifying that it went into approved plans. That is a false certification even though the worker was paid correctly.
Frequently asked questions
Can I just pay the fringe amount as extra hourly wages?
Yes. Paying the fringe rate in cash is fully compliant. It is treated as wages, so it is subject to payroll taxes, and it must appear correctly on the certified payroll and the Statement of Compliance.
Do employer payroll taxes count toward the fringe obligation?
No. FICA, workers' compensation and unemployment insurance are legally mandated, so they cannot be credited against the fringe benefit obligation. Only bona fide benefits the employer is not otherwise required to provide count.
Is fringe paid on overtime hours?
Yes, at straight time. Overtime premium is calculated on the base rate only, but the fringe amount is owed for every hour worked, including hours over 40.
What is annualisation and why does it reduce my credit?
The hourly fringe credit is the annual plan contribution divided by all hours worked in the year, not just Davis-Bacon hours. If you contribute for all hours but divide only by covered hours, you overstate the hourly credit and underpay the worker on covered work.
