One rate, fringe benefits included: $78.25
DLS publishes a single hourly figure that already includes fringe benefits. A contractor can pay it all as wages, or pay part as contributions to bona fide benefit plans for the worker, as long as the two add up to at least $78.25. DLS doesn't publish a base and fringe split, so this page doesn't invent one.
