Washington State has a great number of sales tax zones and these tax rates get updated regularly. You can be set up to integrate directly with the Washington State Department of Revenue Tax API. This means you will import sales tax zones directly from the Washington State Department of Revenue Tax.

Due to API restrictions, ServiceTitan has no way of automatically importing new sales tax zones. This means that when you get a notification that sales tax zones have changed, you must go into ServiceTitan and do a manual import.  Note: The actual sales tax rate for each zone will automatically update every quarter. The Expiration Date column shows how long the current listed rate is good for.
