How New Mexico Sets Workers' Compensation Rates
New Mexico's workers' compensation rates are determined by the Workers' Compensation Administration (WCA) using a state‑wide classification system and the employer's payroll size. Rates are expressed as a dollar amount per $100 of covered payroll and are adjusted annually based on the state's experience rating, medical cost trends, and the overall loss ratio of the fund.

Key Components of the Rate Formula
The formula combines three core elements:
- Base Rate: Set for each job classification (e.g., construction, healthcare) and reflects the average cost of claims for that occupation across the state.
- Experience Modifier: Employers with lower claim frequencies receive a discount, while higher claim histories incur a surcharge.
- Payroll Tier Adjustments: Larger employers (over $1 million payroll) may see different scaling factors than smaller firms.
Recent Rate Changes (2023‑2024)
For the 2024 policy year, the WCA increased the overall loss ratio target to 91 %, prompting modest hikes in most classifications. Notable adjustments include a 3 % rise for commercial construction and a 2 % increase for healthcare services. Employers with an experience modifier below 0.80 benefited from a 0.5 % discount, while those above 1.20 faced an additional 0.7 % surcharge.
Impact on Employers
Employers must recalculate premiums each July when the WCA releases the new rates. Smaller businesses often rely on the state‑run insurance pool, which automatically applies the updated rates to payroll reports. Larger firms typically work with private carriers that incorporate the state rates into their pricing models, adding underwriting margins.
Impact on Employees
Workers' compensation benefits—medical care, wage replacement, and rehabilitation—are funded directly from these premiums. When rates rise, the fund's ability to cover higher medical costs improves, but employers may pass some costs indirectly through wage negotiations or reduced staffing.

What Employers Should Do Now
1. Review the latest classification codes to ensure accurate payroll reporting.2. Conduct a safety audit; reducing claim frequency improves the experience modifier.3. Compare quotes from private carriers if you exceed the state pool's payroll threshold.4. Educate employees on reporting procedures to avoid delayed claims, which can affect future rates.
