Fringe benefits on certified payroll, explained properly

What the obligation actually is

A wage determination sets two numbers for each classification: a base hourly rate and a fringe rate. The contractor owes both. The fringe portion can be discharged by paying bona fide benefits, by paying cash in lieu, or by any combination that adds up.

The rejection happens when the certified payroll claims a fringe credit the contractor did not actually fund in that period.

What counts as a bona fide benefit

Health insurance, retirement contributions, life insurance, and approved apprenticeship training costs. The test is whether an irrevocable contribution was made to a third party, or to a fund, for the benefit of the worker.

What does not count: general overhead, workers compensation, unemployment insurance, or anything the law already requires you to pay. Those are costs of employing somebody, not fringe benefits.

The annualisation trap

Where a benefit covers all hours worked but the contribution is claimed only against public works hours, the credit must be annualised — divided across every hour, not just the prevailing wage ones.

Getting this wrong inflates the apparent credit, which means the worker was underpaid against the determination. That is a back-wage finding, not a rejected filing, and it carries interest.

Cash in lieu is simpler and often safer

Paying the fringe as cash on the paycheque removes the annualisation question entirely. It costs more in payroll tax, and for contractors doing occasional public work it is frequently the cheaper answer once the compliance risk is priced in.

What to check before every submission

That the classification matches the wage determination for that county. That base plus fringe meets or exceeds the determined rate. That every credit claimed corresponds to a contribution actually made in the period. And that the total on the payroll agrees with the total on the pay application.
