What we know about Idaho

Idaho's Professional Employer Recognition Act, Chapter 24 of Title 44 (I.C. 44-2401 et seq.), defines the legal framework, and the state's rulemaking binds the unemployment system to it: IDAPA 09.01.35.134 provides that a professional employer organization must fully comply with the Act to be eligible for any transfers of experience rating allowed by I.C. 72-1349B. The Act's minimum standards (I.C. 44-2405) include maintaining a separate trust account for client funds in an Idaho bank, written professional employer agreements, posting notice to worksite employees of the PEO's role and the identity of the client, and treating the PEO as the employer for state income tax withholding, with unemployment insurance paid under Chapter 13 of Title 72. On the tax side, Idaho gives the PEO two reporting structures, memorialized in the Idaho Department of Labor's PEO packet. Under the first, the client joins the PEO's unemployment account: the PEO must already hold its own UI account, the client completes an Idaho Business Registration (IBR-1) and a PEO Letter of Intent within 180 days of the first Idaho paycheck (I.C. 72-1351(5)), and once the Department closes the client's account and transfers it into the PEO's account, the PEO files for that client under its own account. Under the second structure, the client keeps its own account and the PEO simply reports on its behalf. Whichever structure applies, the PEO must submit an updated client list quarterly, and I.C. 72-1349B(4) requires a separate quarterly wage report for each client reported under the PEO's account - the penalty regime in I.C. 72-1372(h) assesses $100 per client not separately reported, capped at $5,000 per quarter. Experience rating transfers are all-or-nothing: the client and PEO jointly apply within the I.C. 72-1351(5) window, the client's entire experience rate and factors transfer into the PEO's rate with partial transfers prohibited (IDAPA 09.01.35.134.03), the client stays jointly and severally liable for unpaid contributions while the arrangement runs (I.C. 72-1349B), and the experience factors transfer back out when the professional employer arrangement ends. If the joint application is late, the PEO reports the client's wages under the client's own account (IDAPA 09.01.35.134.02). Idaho's 2026 contribution numbers come straight from the Department of Labor's administrative order and rate array: the taxable wage base rises to $58,300 from $55,300, the base tax rate drops 7.5% to 0.729%, the standard (new employer) rate is 1.000% (0.970% UI plus 0.030% workforce development) - the lowest the federal conformity rules allow, per the Governor's office - and no reserve tax is imposed; experience classes run from +1 (0.208%) through +6 (1.000%) on the positive side and -1 (1.250%) through -6 (5.400%) on the deficit side. Minimum wages are a non-event in Idaho: the state rate is simply the federal $7.25. Workers' compensation is a competitive market with a state-adjacent carrier: I.C. 72-301 permits coverage with any insurer authorized by the Department of Insurance, self-insurance with Industrial Commission approval and custodial security, or the State Insurance Fund, which the Industrial Commission describes as a quasi-governmental entity rather than a state agency and which is mandatory only for public employers; more than 300 private carriers are authorized, and NCCI administers the assigned risk pool. Idaho has no statewide paid sick or family leave mandate.
