The Most Important Date for Your Workers’ Comp Premium

Most business owners think about their workers’ compensation premium once a year: at renewal. This is a costly mistake. The key to controlling your premium is set in stone six months before your policy renews.

The Snapshot That Determines Your Premium

Six months after your policy begins, a critical event occurs known as the Valuation Date.

On this day, your insurance carrier takes a snapshot of your claims history and sends it to the national rating bureau. This snapshot—which includes every dollar paid and every dollar reserved for future costs—is used to calculate your Experience Modification Rate (Mod) for the following year.

Once that data is sent, it is nearly impossible to change. The Mod calculated from that snapshot will directly impact the premium you pay for the next 12 months. Assuming the numbers are correct is a gamble you cannot afford to take.

The Problem: Inflated Claim Reserves

The most common source of error in your claims data is the reserve.

A reserve is an adjuster’s educated guess on the total future cost of an open claim. It’s more art than science, and these estimates are frequently inflated. An overstated reserve on your record acts like a real loss, directly increasing your Experience Mod and your premium.

You have a narrow window to ensure this data is accurate. You must review every open claim at least 90 days before your Valuation Date to identify and correct these costly errors.

Your Five-Step Action Plan to Control Costs

To ensure your claim reserves are accurate and your Mod is fair, implement these five steps.

1. Report All Injuries Immediately
The cost of a claim rises dramatically with every day that passes before it is reported. A 24-hour reporting deadline allows the claims process to begin effectively, preventing minor issues from becoming major expenses. Delayed reporting leads to lost control and higher costs.

2. Maintain Consistent Communication
Stay in contact with your injured employees. Consistent communication demonstrates your commitment to their well-being, which fosters cooperation and encourages a faster recovery. It also provides you with direct insight into the progress of the claim and their readiness to return to work.

3. Drive an Early Return-to-Work
Getting an employee back on the job, even with modified duties, is the single most effective way to control claim costs. In many states, a timely return-to-work can significantly discount the claim’s impact on your Mod. It stops payments for lost time, keeps the employee engaged, and dramatically increases the likelihood they will ever return to full duty.

4. Audit All Open Claims Before the Deadline
Your claims adjuster manages hundreds of files. You only need to manage yours. Ninety days before your Valuation Date, work with your agent to conduct a thorough review of all open claims. Scrutinize the reserves. If an estimate seems too high based on the claim’s progress, you must work with your agent to present a case to the adjuster for a reduction.

5. Engage with the Treating Physician
Often, a lack of updated medical information is what keeps a reserve artificially high. An adjuster may not have the time to chase down a doctor for a status update. Proactively facilitate that communication. When a physician understands the employee’s job duties and your commitment to a safe return-to-work plan, they become a partner in managing the claim outcome.


Your workers’ compensation premium is not a fixed cost. It is the direct result of a process you can and should manage. By focusing on your open claims well before your Valuation Date, you can correct errors, challenge excessive reserves, and take control of what you pay.
