(Effective 1/1/2016)


The Renton B&O tax is a gross receipts tax. 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 Renton, you must have a Renton business license and file a B&O tax return.

Businesses are subject to the B&O tax if the annual taxable revenue is above the following thresholds:

  • 2016 - $1.5 million
  • 2017 - $1.5 million
  • 2018 - $500,000

Until January 1, 2018, businesses under the threshold were also required to pay the per employee license fee. 

The Renton B&O tax is not the same as the Washington State B&O tax. Renton 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.

Annual Tax Cap:
The B&O Tax imposed shall not exceed more that the set cap limit (per business) which shall be adjusted each January to reflect the inflation adjustment. Below is the maximum tax for each respective year.

  • 2016 - $4,250,000.00
  • 2017 - $4,335,709.75
  • 2018 - $4,465,059.75
  • 2019 - $4,622,830.00
