Washington Farm Workers' Comp: Agriculture & H-2A Coverage

Most states carve agriculture out of their workers' compensation laws with payroll, headcount, or seasonal-worker thresholds. Washington does not. Under RCW 51.12.020, agricultural employment is covered like any other industry: employ one farm worker, full-time, part-time, or a picker who shows up for a single weekend of harvest, and that worker must be covered. The statute's only agriculture-specific exclusion is a child under 18 employed by his or her parent or parents in agricultural activities on the family farm. That is the entire list. There is no small-farm exemption, no seasonal exemption, and no exemption for H-2A guest workers.

The second thing that surprises out-of-state operators: Washington is one of the four monopolistic state-fund states. Coverage must be purchased through the Washington State Fund, administered by the Department of Labor & Industries (L&I). Private insurance carriers are not permitted to sell workers' compensation in Washington; the only alternative to the State Fund is self-insurance, which requires state approval and is realistic only for very large employers. In practice, every farm in the state opens an L&I account, reports worker hours each quarter, and pays premium directly to the same agency that regulates its claims.

For a grower, that changes what "shopping your workers' comp" even means. There is no second carrier to quote against L&I. The cost levers that remain all live inside your own account: correct risk-class assignment for each kind of work performed, accurate quarterly hour reporting, disciplined claim handling, and the experience factor those claims produce over time.

Washington certified 35,884 H-2A positions in FY2024, the fourth-largest total of any state and roughly 9.3 percent of the 384,900 positions certified nationwide, edging up from 35,680 in FY2023 before easing in FY2025. The program is concentrated in tree fruit: apples above all, where H-2A crews now pick a large share of the state's crop, along with cherries, berries, and pears across the Yakima Valley, Wenatchee, and the Columbia Basin.

Federal law stacks its own workers' comp requirement on top of the state rule. Under 20 CFR 655.122(e), every H-2A employer must provide workers' compensation insurance in compliance with state law, covering injury and disease arising out of and in the course of the worker's employment. Where a state exempts farm labor from its workers' comp statute, the regulation requires the employer to purchase equivalent coverage at no cost to the worker. In Washington the overlay is simpler than in exemption states: because state law already covers every agricultural worker, your H-2A crew is insured through your L&I account exactly like your domestic crew.

What actually trips up Washington H-2A filers is the proof requirement. Under 20 CFR 655.122(e)(2), before the temporary agricultural labor certification is issued, the employer must provide the DOL certifying officer with proof of coverage: the insurance carrier's name, the policy number, and proof of insurance for the entire period of employment, or, where it applies, proof of coverage under state law. For a Washington farm that means documentation that your L&I account is open and in good standing for the full contract period. An account that lapsed over the winter, or was never updated after an entity change, can stall a certification with workers already booked and buses already chartered.
