The Shoreline B&O tax is a gross receipts tax effective January 1, 2019. It is measured on the value of products, gross proceeds of sales, or gross income businesses earn.

There are no deductions for labor, materials, rent, or other costs of doing business. If you do business in Shoreline and generate equal to or more than $2,000 in gross receipts annually, you must have a Shoreline business license and file a B&O tax return.

Businesses are subject to the B&O tax if the annual taxable revenue is above $500,000 in 2019.

The Shoreline B&O tax is not the same as the Washington State B&O tax. Shoreline taxes must be filed separately from your state taxes. For more information on the Washington B&O tax please visit Washington State Department of Revenue.

On December 4, 2017 the City Council adopted a B&O tax in Shoreline. All businesses operating in Shoreline that have gross receipts in excess of $500,000 per year (or $125,000 per quarter), except 501(C)(3) non-profits, will be subject to the tax effective January 1, 2019. A rate of 0.001 will be applied to all gross receipts for all business classifications except services which will be taxed at a rate of 0.002.

Two workshops were held in June 2017 to provide information to businesses on the City’s financial forecast and budget, and to collect feedback on the potential B&O tax. For more information please see the Business Outreach Workshop Presentation and City of Shoreline Services Video.

The City of Shoreline, like most cities in Washington, faces a structural imbalance in funding core operations, where the cost of maintaining services is growing faster than the revenues available to support them.

In 2014, the City Council developed a 10 Year Financial Sustainability Plan that identifies seven strategies to help achieve financial sustainability over the 10 year forecast. Five of the seven strategies have been implemented, and the City forecasts sufficient revenues through 2021, primarily relying on a voter-approved levy lid lift that expires in 2022.
