Most general contractors working on Davis-Bacon or prevailing wage projects must decide how to satisfy the fringe benefit portion: pay the fringe benefit portion in cash, pay non-cash fringes through a bona fide benefit plan, use a combination of the two, or pay a base rate high enough that it covers the fringe obligation on its own. On the surface, cash looks easier. In practice, the choice has significant implications for payroll taxes, workers' compensation premiums, employee retention, and bid competitiveness.
Here is what general contractors need to know about how
Davis-Bacon fringe benefits work, and the real pros and cons of each payment
method.
What Are Davis-Bacon Fringe Benefits?
Under the Davis-Bacon Act and most state prevailing wage
laws, the wage determination for each job classification has two parts: a basic
hourly rate and a fringe benefit rate. Together, these make up the total
prevailing wage that must be paid to each worker.
Contractors satisfy the fringe portion in one of three ways:
Cash fringe benefits: Pay the full fringe rate as additional taxable wages directly to the worker.
Bona fide fringe benefits: Contribute the fringe rate to qualified benefit plans on the worker's behalf. Common examples include health insurance, retirement plans, life insurance, vacation, and apprenticeship training programs.
Hybrid Approach: Pay part of the fringe rate to a
bona fide plan, and the remainder in cash to satisfy the wage determination.
Pros and Cons of Paying Fringe Benefits in Cash
Pros of Cash Fringe Benefits
Simplicity. Cash fringe is the easiest method to administer. No benefit plans to set up, no third-party administrators, and no annualization calculations. The full fringe rate goes on the paycheck and is entered separately as a cash fringe on the certified payroll report.
Worker visibility. Crews see the full hourly rate on every check, which can simplify recruiting and retention conversations in tight labor markets.
Flexibility for short-term workers. For temporary or
short-duration crews, cash avoids the administrative burden of enrolling
workers in benefit plans they may not stay long enough to use.
Cons of Cash Fringe Benefits
Higher payroll tax burden. Cash fringe is treated as taxable wages. Contractors owe the full employer share of FICA, Medicare, FUTA, and SUTA on every fringe dollar, plus workers' comp premiums and, in some cases, other insurance costs calculated on wages. On a $12 fringe rate, that can add several dollars per hour in additional costs.
Lost bid competitiveness. Because cash fringe inflates the contractor's burden rate, contractors paying cash fringe often submit higher bids than competitors using bona fide plans. On large public works projects, that gap can decide who wins the contract.
No tax-advantaged benefit for workers. Cash fringe is fully taxable to the worker. The same dollars routed through a qualified retirement or health plan would build pre-tax value the worker keeps.
Weaker retention. Crews paid entirely in cash have no
benefit ties to the contractor, making it easier for competitors to poach them
between projects.
Pros and Cons of Bona Fide Fringe Benefit Plans
Pros of Bona Fide Plans
Lower payroll burden. Contributions to qualified bona fide benefit plans are not subject to FICA, Medicare, FUTA, SUTA, workers' comp, or general liability premiums. On a single $12 fringe rate, the savings can amount to thousands of dollars per worker per year.
More competitive bids. Lower burden rates translate directly into lower bid numbers. Many contractors who switch from cash to bona fide plans find their win rate on public works bids improves significantly.
Real value for workers. Health insurance, retirement contributions, and apprenticeship training deliver pre-tax value that cash never matches. This strengthens recruiting and retention, particularly for skilled trades.
Tax-advantaged growth. Retirement contributions
through a bona fide plan grow tax-deferred for the worker, providing long-term
financial benefit beyond the project itself.
Cons of Bona Fide Plans
Setup and administration. Establishing qualified plans takes time, requires a plan administrator, and involves ongoing compliance work. For contractors new to prevailing wage, this is a real barrier.
Annualization requirements. The DOL requires that benefit costs be annualized, meaning contributions must be spread across all hours worked - not just prevailing wage hours. Getting annualization wrong is a common audit issue.
Documentation burden. Contractors must document the actual value of contributions per worker per hour and prove the plan qualifies as bona fide under DOL rules. This requires accurate payroll records and benefit reporting tied directly to certified payroll submissions.
Less flexibility. Once benefit plans are in place,
switching contribution levels mid-project or per-classification gets
complicated.
Which Approach Makes Sense for Your Business?
The right answer depends on the size of your prevailing wage workload and your competitive position.
Cash fringe often makes sense when: You run occasional Davis-Bacon work, your crews are small, mostly short-term, or you are still building toward consistent public works volume.
Bona fide plans usually win when: Public works is a meaningful share of your revenue, you have stable crews you want to retain, and you need every margin of competitiveness to win larger bids.
Some contractors land on a hybrid model, using a bona fide
retirement or health plan for the bulk of the fringe rate and paying any
shortfall cash. This captures most of the tax advantage when plan contributions
fall below the required fringe rate.
How eMars Handles Fringe Benefit Reporting
Whether contractors choose cash, bona fide, or a hybrid approach, certified payroll reporting still has to reflect every fringe dollar correctly. eMars automates this on every WH-347 and state-specific form, producing fully populated reports directly from payroll data with the right fringe allocation per worker per hour.
For general contractors managing both federal Davis-Bacon and state prevailing wage projects, this removes the manual reconciliation work that creates audit risk.
