For Insurers

Premium tax reporting requirements

Who is required to file a premium tax return?

All insurers licensed to do business in Washington state during the tax year must file an electronic tax form even if no business was actually transacted within Washington during that time.

All purchasing groups and risk retention groups admitted in Washington are required to file an electronic tax form, even if no business was transacted or someone else is responsible for paying the premium taxes.

Additionally, all surplus line broker business entities and certain individuals whose surplus line licenses were active during the tax year must complete a form, even if no business was actually transacted. Review surplus line broker requirements to determine if you are required to file.

How do I file a premium tax return?

User credentials were issued to your entity's tax contact. If you are not sure who your tax contact is, you can use the Filing and Payment Center sign in page to find your tax contact - you just need your WAOIC number or NAIC number.

When are premium tax forms available?

Tax forms are generally available for completion in mid-January. Your tax contact will receive an email when the forms become available.

When are premium tax filings due?

Premium tax filings and payments must be submitted on or before March 1 of each year. When the due date falls on a Saturday or Sunday, the next business day is considered timely.

My organization is entitled to a premium tax refund. How and when do I receive the refund?

Once we have received and audited your filing, we will determine if your company will have prepayments in the current year. If so, we will retain any refund amount up to the total of prepayments for the year. If prepayments are not due, or if the refund exceeds the total prepayments, we will mail a refund check to your tax contact.

I submitted my company's tax return form, but discovered an error. How do I correct my tax return?

You will need to file an amended tax form.
