Fringe benefits under Davis-Bacon vs California prevailing wage
Both systems let you satisfy part of the wage obligation through a health, pension, or vacation plan instead of straight cash. They do not treat that credit the same way. Federal Davis-Bacon rules let you shift cash freely between the base rate and a benefit plan, as long as the combined total meets the wage determination, per the U.S. Department of Labor's own compliance principles page. California's Labor Code section 1773.1 and its regulations will not let that same shift touch the cash wage floor.
The one difference that causes the most trouble
A federal wage determination states one combined number: a basic hourly rate plus a fringe rate, adding up to a total. Davis-Bacon does not require you to protect the basic hourly rate as its own cash floor. The Department of Labor's own worked example shows a determination requiring $34.00 in basic pay plus $21.00 in fringe benefits, a $55.00 total. That $55.00 can be paid as straight cash, as $34.00 cash plus $21.00 into a bona fide plan, or as $32.00 cash plus $23.00 into a plan. All three meet the determination, because Davis-Bacon only cares that the combined total is met.
California splits the same rate into two named layers on every wage determination: the Basic Hourly Rate and Employer Payments. Under 8 CCR section 16200(a)(3)(I), a contractor can credit actual fringe benefit spending against the Employer Payments layer, but "no amount of credit for payments over the aggregate amount of employer payments shall be taken nor shall any credit decrease the amount of direct payment of hourly wages" designated as prevailing for straight time or overtime. In plain terms, the third option in the federal example above, trading $2.00 of cash for a bigger plan contribution, is not legal on a California public works job.
What counts as a fringe benefit, side by side
| Federal: Davis-Bacon | California: prevailing wage law | |
|---|---|---|
| Where the list lives | Bona fide fringe benefit definition in the Department of Labor's Davis-Bacon FAQ, question 29 | Labor Code section 1773.1(a) |
| What it covers | Life insurance, health insurance, pension, vacation, holidays, sick leave, and defrayment of apprenticeship or training program costs under 29 CFR 5.29 | Health and welfare, pension, vacation, travel, subsistence, apprenticeship training, worker protection committee costs, and industry advancement or administrative fees under a collective bargaining agreement |
| What is excluded | Legally required payments: Social Security, unemployment insurance, workers' compensation | Same exclusion |
| Structure of the credit | One combined rate. Cash and benefits are interchangeable up to the total. | Two layers. Credit only reaches the Employer Payments layer, per 8 CCR 16200(a)(3)(I) |
California's Employer Payments definition itself, in 8 CCR section 16000, breaks into three sources of credit: irrevocable contributions to a trustee or third party for the benefit of employees or retirees, the reasonably anticipated cost of a written, communicated, financially responsible unfunded plan, and irrevocable contributions to an apprenticeship program authorized under Labor Code sections 3071 or 3093. That is close to the federal definition of a bona fide plan, but it only ever offsets the Employer Payments number, never the Basic Hourly Rate under it. Our fringe benefit statement guide covers turning a plan's cost into an hourly credit.
Annualization: a compliance principle vs a rewritten statute
Both systems require you to spread a fringe benefit contribution across the hours it actually covers, not credit a lump payment against one short workweek. They differ in scope, and California's rule just changed.
Federally, annualization applies by default to every fringe benefit contribution, not to any one plan type. Under 29 CFR 5.25(c), a contractor must annualize contributions to a fringe benefit plan, dividing the total cost by all the hours it covers, covered and non-covered, to find the honest hourly credit. The point, per the Department of Labor's compliance principles page, is to stop Davis-Bacon work from becoming the disproportionate or exclusive funding source for a benefit that is continuous in nature on both covered and non-covered work. Defined contribution pension plans get an automatic exception from that same annualization requirement when the plan offers immediate participation and vesting within the first 500 hours worked. That exception is the same shape as the AB 889 carve out described below, not a rule built to target DC pension abuse.
California's version sits in Labor Code section 1773.1(e). Assembly Bill 889, enacted as Chapter 626 of the Statutes of 2025, effective January 1, 2026, requires annualization "when the employer seeks credit for employer payments that are higher for public works projects than for private construction," and revoked every exemption the Director of Industrial Relations had issued before that date. It added one narrow carve out: a defined contribution pension plan can be credited hour for hour without annualizing if it offers both immediate participation and vesting within 500 hours. Outside that, if your plan costs more on public jobs than private ones, you annualize the difference and keep records to prove the calculation on request.
What both sides let you do the same way
- Pay it all in cash. Both laws let you skip a benefit plan entirely and pay the full determination rate, base plus fringe, as straight wages. Nobody's total pay changes; only where the money goes does.
- Fund the plan less often than every paycheck. Federally, 29 CFR 5.5(a)(1)(i) requires contributions "not less often than quarterly." California's Labor Code 1773.1(d) allows the credit "even if contributions are not made... during the same pay period for which credit is taken," as long as the employer funds the plan regularly, on no less than a quarterly basis. Quarterly is the floor on both sides, not a target to aim for.
A side by side worked example
Run the Department of Labor's $34.00 base plus $21.00 fringe determination both ways, for one worker, one hour.
| Pay split | Meets Davis-Bacon | Meets California prevailing wage |
|---|---|---|
| $55.00 all in cash | Yes | Yes |
| $34.00 cash, $21.00 to a bona fide plan | Yes | Yes |
| $32.00 cash, $23.00 to a bona fide plan | Yes, per DOL's own example | No. 8 CCR 16200(a)(3)(I) bars any credit that decreases the direct hourly wage payment below the amount designated as prevailing |
The last row is where a payroll built for a federal contract fails a California one. On a project that also counts as California public works, that $2.00 has to come back out of the plan and land in the paycheck instead.
When a project owes both
On federally assisted work a California awarding body controls, California's Employer Payments floor governs on top of Davis-Bacon, not instead of it. Our federal vs state certified payroll guide covers which wage rate wins when the two determinations differ and how apprenticeship rules stack. A travel or subsistence payment on the same determination is a separate per diem wages category, covered in our per diem, travel, and subsistence guide, and training fund contributions run through their own filing, walked through in our CAC training fund contributions guide.
