Why Ohio Is “Monopolistic” & What That Means for Employers

Ohio is one of only four “monopolistic” states—along with North Dakota, Washington and Wyoming—where employers must purchase workers’ compensation insurance directly from a state fund. In Ohio, that fund is administered by the Ohio Bureau of Workers’ Compensation (BWC). No private carrier can sell a standard workers’ compensation policy for Ohio payroll, although businesses may self-insure if they meet stringent financial criteria.

Key implications for employers

• One filing jurisdiction, one set of rules, one billing calendar.
• Premiums are paid to the BWC, typically two installments per policy year (due Jan. 31 & June 30 for private employers).
• Experience modifiers, discounts and surcharges are calculated only by the BWC.
• Multi-state employers must carve out Ohio payroll from any multi-state policies and report it to the BWC separately.

For guidance on juggling multiple jurisdictions, see our companion guide: Multi-State Employers: How to Navigate Conflicting Workers' Compensation Insurance Laws.

Who Must Carry Coverage in Ohio?

Ohio Revised Code 4123.01 requires every employer with one or more employees—full-time, part-time or seasonal—to secure coverage, including:

• Corporations with officers on payroll
• LLCs with employees (members may elect coverage)
• Construction contractors who hire subcontractors without their own BWC policy
• Agricultural operations with >1,000 hours of labor in any quarter

Exemptions

• Sole proprietors, partners and LLC members may elect to cover themselves.
• Domestic servants in private homes are generally exempt.

How Premiums Are Calculated

Ohio uses a three-part formula:

Premium = (Payroll ÷ 100) × Base rate × EMR + Assessments

Example: A manufacturing firm with $2 million Ohio payroll, EMR = 0.85
Premium = ($2 M / 100) × $0.68 × 0.85 ≈ $11,560 before assessments.

Recent Rate Cuts & 2026 Premium Outlook

Ohio continues to slash rates:

• July 1 2025: 6 % average cut for private employers—projected $60 million in savings statewide (workcompwire.com)
• Jan 1 2026: 1 % cut for public employers—≈ $1.8 million saved (workcompwire.com)

Thanks to consecutive reductions, Ohio’s premium index fell from $0.83 in 2022 to $0.68 in 2024 and is projected to hover near $0.65 in 2026, keeping the state among the five lowest-cost jurisdictions nationally (ohiomfg.com).

Savings Programs: Group Rating, Group-Retro & Grow Ohio

Even with low base rates, savvy employers leverage BWC incentive programs:

Sedgwick example: The state’s largest TPA reports $160 million in annual client savings and $4 billion saved over the last decade through group programs (ohiocpa.com).

Key Players: BWC, MCOs & Third-Party Administrators (TPAs)

1. Bureau of Workers’ Compensation (BWC)

• Issues policies, sets rates, adjudicates claims.
• Operates 10 regional customer care centers.

2. Managed Care Organizations (MCOs)

• Medical-only; they coordinate treatment, RTW and bill review.
• Employers choose an MCO every two years during the open-enrollment window.

3. TPAs (Sedgwick, CareWorks Comp, CompManagement)

• Handle risk consulting, claims advocacy, program enrollment.
• Typical annual fee: $400–$1,200 flat, or ~ 0.15 % of covered payroll for large accounts (market survey).
• Provide free feasibility projections before enrollment.

Pro-Tip: Compare at least two TPAs; Sedgwick touts an 11:1 ROI—every $1 in fees yields $11 in premium savings (cbao.bank).

Step-by-Step: Registering & Maintaining Your Policy

1. Create OH|ID and log into the BWC eBusiness portal.
2. Complete U-3 Application → Pay $120 minimum deposit.
3. Receive Policy & Risk Classifications within 10 business days.
4. Report Payroll & Pay Premiums (Jan 31 / Jun 30).
5. Elect Savings Programs (Group, Grow Ohio, ISSP).
6. Complete Two-Hour Safety Training if claims exceed $15k.
7. Submit True-Up Report each August.

Claims Process: From Injury Report to Return-to-Work

1. Injury occurs → provide First Report of Injury (FROI) within 24 hours.
2. MCO contacts employee & assigns nurse case manager.
3. BWC claim number issued (goal: 72 hours).
4. Initial compensation decision within 28 days.
5. TPA coordinates light duty & wage differential if applicable.
6. EMR impact appears two policy years later.

Compliance & Penalties for Non-Coverage

Failing to secure or maintain coverage designates you a “non-complying employer.” Penalties include:

• Retroactive premium assessment for entire uncovered period.
• Additional penalty up to 10× the missing premium for intentional misclassification (codes.ohio.gov).
• Civil action by injured workers with no statutory cap on damages.
• Personal liability for corporate officers.

Cost-Containment Best Practices

• Safety councils & grants: Earn 3 % rebate for attending 10 meetings.
• Drug-Free Safety Program: 4–7 % premium credit.
• Dedicated RTW coordinator: cut indemnity days by 30 %.
• Annual EMR audit—errors can inflate premiums 15 %.
