Domestic property and casualty companies - 2018 premium tax filing instructions

New for 2018

There are no changes from 2017 for the domestic property and casualty tax forms.

Filing requirements

All property and casualty insurance companies licensed in the State of Washington during the calendar year must file an online tax form, as provided by this office, even if no business was actually transacted within Washington during that time. Alternate filing methods are not accepted.

Due date

The completed online form and payment must be received by the Office of Insurance Commissioner (OIC) on or before March 1 following the end of the calendar year. When the due date falls on a Saturday or Sunday, the form and payment are considered timely if received on the next business day.

 Caution: Do not mail a paper version of the form or any attachments to our office.

Completing your premium tax form

Tax is generally due on all premiums, unless specifically exempted on the tax form. If you have questions, please contact us.

Premiums reported must be on the same basis as required on the Annual Statement.

The tax rate is 2%. Calculations will be completed automatically.

Selecting "Print" will print your form exactly as it appears on the screen, even if you have not saved your work.

Clicking the "Save Progress" button does not check for errors.

 Remember: Save your work before moving away from the form; your work is not automatically saved.

Premium Reporting section

Premiums as Reported on the Annual Statement

Premiums entered in this section should, with few exceptions, match premiums reported for Washington on the corresponding lines of the Exhibit of Premiums and Losses (state page) filed with the NAIC.

Excess Bail Bonds are bail bond premiums and fees in excess of those reported on the state page and are not included in Line 24 or 34; please report these premiums using the unnumbered line under Line 34.

Schedule A - Property/Casualty Taxes

Most fields on this schedule are populated from the Premium Reporting section of the tax form.

If your company received premiums from unauthorized areas, report them on this schedule.

The Health Pool Assessment Available is displayed on this schedule. If the credit available would reduce taxable premiums below zero, the excess credit is carried forward to the next tax year.

Schedule B - Ocean Marine Taxes

Some fields on this schedule are populated from the Premium Reporting section of the tax form.

Report Reinsurance Assumed, Reinsurance Ceded, Direct Losses Paid, Losses Paid on Reinsurance and Recoveries on Reinsurance Ceded on this schedule.

Schedule C - Assessment Credits

Assessment credits are pre-populated by the OIC and cannot be edited. Assessment credits are prorated at 20% per year for five years, unless the credit balance falls under $1,000.

Example: Your company pays an assessment of $2,000 in calendar year 2015.

Year 1 (2015): Credit of $400 used, balance of $1,600.

Year 2 (2016): Credit of $400 used, balance of $1,200.

Year 3 (2017): Credit of $400 used, balance of $800.

Year 4 (2018): Credit of $800 used, balance of $0.

Schedule D - Filing and Miscellaneous Fees

If your company is no longer active in Washington and this is your final return, enter $0 as the Certificate of Authority Renewal Fee.


All fields in this section are populated from other areas of the the tax form.

2018 premium tax overpayments, if any, will be applied to prepayments due for 2019. Overpayments in excess of 2019 prepayments due will be processed as refunds and sent to the attention of the tax contact we have on file.
