Insurance companies that increase premiums when your home or auto policy renews will be required to disclose up to three primary reasons for the change, starting in March 2027.
“This is basic information that should be available to anyone with an insurance policy,” Washington state Insurance Commissioner Patty Kuderer said. “If your premiums are going up, you deserve to know why. This is an important rule and a key change in how it’s implemented.”
The change to Washington’s transparency rule applies to auto and home insurance policies, including manufactured home, condominium, and renter insurance.
The transparency rule originally took effect on June 1, 2024, and was the first of its kind in the country. It requires that:
- Insurance companies must provide a reason for increasing consumers’ premiums upon renewal when consumers ask in writing. Companies must provide a clear, concise response in writing within 20 days.
- Renewal notices and billing statements must include a disclaimer that tells consumers how to request the information.
- Starting in November 2026, insurance companies must provide an email address for consumers to send their requests.
The final stage of the rule’s adaptation takes effect in January 2029 and will require insurance companies to proactively communicate to consumers when they increase premiums by 10% or more.
