Texas Workers' Comp Guide for Contractors: What You Actually Need to Know

Texas is the only state in the country where workers' compensation insurance is not mandatory for most private employers. That's a legal distinction with major practical implications — and it creates real confusion for contractors, especially those working under GC contracts that require WC certificates.

This guide covers what Texas contractors actually need to know about the WC system: when it's required, how it works, what it costs, and when the non-subscriber alternative makes sense.

Texas WC: The basics

Texas operates a voluntary workers' compensation system. Private employers can choose to carry workers' comp through the state-regulated system, or they can opt out and become a "non-subscriber."

This is fundamentally different from every other state. In most of the country, if you have employees, you have to carry WC. In Texas, you can decline — but opting out comes with legal consequences that contractors often don't fully understand before they make the choice.

When Texas WC is effectively mandatory

Even though Texas law doesn't require WC for most private employers, there are several situations where contractors effectively have no choice:

Public-sector projects: State agencies, cities, and counties require WC from all contractors working on public projects. If you're bidding on municipal construction, school district work, or state agency projects in Texas, WC is required regardless of your preference.

Federal construction work: Federal projects require WC from all covered employers, and federal law takes precedence over Texas's optional WC framework.

GC subcontract requirements: Many Texas general contractors require WC certificates from subcontractors as a contract condition. This is extremely common in commercial construction. Read your subcontract before assuming you can operate without WC.

Lender and surety requirements: Some project lenders and surety bond programs require WC documentation from contractors. Without it, you may not qualify for bonding or financing on larger projects.

How Texas WC class codes work

Workers' comp premiums are calculated using class codes that correspond to the type of work your employees do. Each class code carries a base rate — the premium per $100 of payroll for workers in that category.

In Texas, common contractor class codes include:

• Roofing (class 5551): One of the highest-rated codes in Texas due to fall hazard risk
• Framing (class 5645): Wood frame construction, including rough carpentry
• Electrical (class 5190 or 5191): Interior wiring vs. outside electrical work
• Plumbing (class 5183): All types of plumbing installation
• HVAC (class 5537): Heating, ventilation, and cooling installation
• Concrete (class 5213): Poured concrete structures
• General contractor (class 5403): GC supervision and construction management

Wrong class codes are the #1 cause of WC audit surprises. If your roofers are coded as general laborers, the auditor will catch it at year-end and assess additional premium at the roofing rate.

The Texas non-subscriber tradeoff

A Texas non-subscriber is a private employer who has opted out of the state WC system. Non-subscribers can design their own benefit programs — or have no formal injury benefits at all — but they take on significant liability exposure.

Under Texas law, employees of non-subscribers can sue for negligence without the standard defenses available to WC-participating employers:

• No contributory negligence defense: The employer can't argue that the employee's own negligence caused the injury
• No fellow servant defense: The employer can't argue that a coworker's negligence caused the injury
• No assumption of risk defense: The employer can't argue the employee knew and accepted the risk

This creates substantial jury trial exposure. Texas non-subscriber cases have resulted in verdicts in the millions for serious injuries.

Non-subscriber status makes the most sense for:

• Sole operators with no employees who do private work for homeowners or commercial property owners who don't require WC certificates
• Businesses with very few employees doing low-hazard work where GCs don't require WC certificates
• Employers who understand the liability exposure and have a clear private benefit plan in place

Non-subscriber status is a poor choice for:

• Contractors with multiple employees doing high-hazard work
• Any contractor bidding on public-sector projects in Texas
• Subcontractors whose GC contracts require WC certificates
• Roofing, HVAC, electrical, or framing contractors where injury risk is real and lawsuit exposure is significant

What Texas WC actually costs

Texas WC premium depends on three primary factors: your class codes, your total payroll, and your loss history (experience modification rate).

For a roofing contractor with $300,000 in annual payroll, at a roofing class code rate of approximately $18–$25 per $100 of payroll (rates vary by carrier and market), annual premium might run $54,000 to $75,000. That's a real number — but compare it to a non-subscriber negligence verdict.

For a framing contractor at $500,000 payroll, at framing rates of approximately $6–$10 per $100, annual premium might run $30,000 to $50,000.

For a small HVAC contractor with $150,000 payroll, at HVAC rates of approximately $4–$7 per $100, annual premium might run $6,000 to $10,500.

These are rough ranges — your actual premium depends on the specific carrier, your experience modification rate, and the exact classification of your work. We quote your actual trade and payroll and present real numbers.

How to get Texas WC right

The most common mistakes Texas contractors make with WC:

1. Wrong class codes from day one: Work with an agent who classifies your work correctly — not just puts you in a generic "contractor" code
2. Not tracking subcontractor certificates: GC clients need proof that subs carry their own WC; without it, the GC's policy may include sub payroll at audit
3. Not reviewing the certificate before using it: WC certificates need to show the right limits, the right additional insured, and the correct effective dates
4. Lapsing coverage mid-year: A gap in WC coverage can cost you projects and create liability exposure for the lapse period
