Ohio Business Insurance Guide: Understanding the BWC Monopolistic System

Ohio operates one of the most unique workers’ compensation systems in the nation. As one of only four monopolistic fund states, Ohio requires most employers to obtain workers’ comp coverage exclusively through the Ohio Bureau of Workers’ Compensation (BWC)—not from private insurance carriers. Understanding this system is essential for any business operating in the Buckeye State.

Ohio’s Monopolistic Workers’ Compensation System

Ohio is one of only four states with a monopolistic workers’ compensation fund (along with North Dakota, Washington, and Wyoming). This means:

  • No private market - You cannot buy workers’ comp from insurance companies
  • Single provider - Ohio BWC is your only option (with limited exceptions)
  • State-administered - Government agency sets rates and manages claims
  • Different rules - Many traditional insurance strategies don’t apply

How Ohio BWC Works

Premium determination:

  1. BWC assigns your business a classification code
  2. Base rates are set by BWC (not negotiable)
  3. Your experience modifier adjusts the base rate
  4. Various discounts and programs can reduce premiums
  5. Premium paid directly to BWC

Claims process:

  1. Injured worker reports to employer
  2. Employer files First Report of Injury with BWC
  3. BWC manages the claim directly
  4. Medical providers bill BWC
  5. Wage replacement paid by BWC

Who Must Have BWC Coverage

Covered employers:

  • All employers with one or more employees
  • Corporations (officers are employees)
  • LLCs with employees
  • Partnerships with employees outside the partnership
  • Public employers (separate public employer division)

Exempt from coverage:

  • Sole proprietors with no employees
  • Partnerships (partners only, no employees)
  • Family farm operations (immediate family only)
  • Domestic workers (under 40 hours/week)
  • Real estate agents (independent contractors)

Sole Proprietor and Partner Elections

Sole proprietors and partners can elect to cover themselves:

  • Optional coverage at standard rates
  • Provides workers’ comp protection for business owners
  • Must actively elect—not automatic
  • Recommended if work involves physical risk

Ohio BWC Premium Rates

Ohio’s workers’ comp rates are generally lower than national averages due to system reforms.

Sample Base Rates by Industry

Industry ClassificationRate per $100 PayrollExample: $500K Payroll
Clerical/Office (8810)$0.13 - $0.25$650 - $1,250
Retail Store (8017)$0.50 - $1.00$2,500 - $5,000
Restaurant (9082)$0.80 - $1.50$4,000 - $7,500
Construction - General (5645)$3.50 - $7.00$17,500 - $35,000
Roofing (5551)$12.00 - $20.00$60,000 - $100,000

Rates shown are base rates before experience modification and discounts

Ohio vs. Other Large States

StateAverage WC CostSystem Typevs. Ohio
Ohio$0.97/$100MonopolisticBaseline
Pennsylvania$1.32/$100Private+36%
Illinois$1.45/$100Private+49%
New York$1.89/$100Private+95%
California$2.27/$100Private+134%

Ohio’s monopolistic system delivers some of the lowest workers’ comp costs among large industrial states.


Group Rating Programs: Ohio’s Biggest Savings Opportunity

Group rating is Ohio’s most significant workers’ comp cost reduction strategy—and it’s unique to monopolistic fund states.

What Is Group Rating?

Group rating allows employers with good safety records to pool their experience with similar employers to achieve lower rates:

  • Pooled experience - Your experience modifier blends with the group’s
  • Significant discounts - Savings of 25-95% off base rates possible
  • Industry-specific groups - Join groups in your industry
  • Managed by TPAs - Third-party administrators run the programs
  • Annual enrollment - Must apply each year

How Group Rating Discounts Work

Group Performance LevelTypical Discount Range
Best performing groups85-95% off base rate
Above average groups70-85% off base rate
Average groups50-70% off base rate
Entry-level groups25-50% off base rate

Group Rating Example

Retail employer with $500,000 payroll:

ScenarioCalculationAnnual Premium
Base rate (no programs)$500K × $0.80/$100$4,000
With 50% group discount$4,000 × 50%$2,000
With 80% group discount$4,000 × 20%$800

Savings potential: $2,000 - $3,200 per year in this example.

Qualifying for Group Rating

Requirements:

  • Clean or minimal claims history
  • Meet minimum premium thresholds
  • Comply with group safety requirements
  • Pay TPA administrative fees
  • Maintain good standing

Disqualifying factors:

  • Recent serious claims
  • High claim frequency
  • Poor experience modifier
  • Safety violations
  • Late premium payments

Finding a Group Rating Program

Groups are sponsored by:

  • Trade associations - Industry-specific groups
  • Chambers of commerce - Regional business groups
  • TPAs (Third Party Administrators) - Commercial sponsors
  • Professional associations - Occupation-based groups

Major Ohio TPAs:

  • CompManagement
  • Sheakley
  • CareWorks
  • Sedgwick
  • OSIA (Ohio Self-Insurers Association)

Group Retrospective Rating

An alternative to group rating for larger employers:

  • Risk sharing - Employers share in claim costs and savings
  • Potential refunds - Good experience returns premium
  • Potential assessments - Poor experience may cost more
  • Larger employers - Generally $10,000+ premium required

Self-Insurance in Ohio

Larger Ohio employers can apply to self-insure workers’ compensation.

Self-Insurance Requirements
