What is the B&O tax?

The B&O tax is a gross receipts tax levied upon a person or company for the act or privilege of doing business, whether the person’s office or place of business is located within or outside of the city limits of Kent. It was established effective January 1, 2013 to pay for critical street repairs within the City and to ensure a safe and efficient transportation system.

What are the B&O tax Classifications and Rates?

The B&O tax has two components: gross receipts tax and square footage tax. Taxpayers located within the city will report in both the gross receipts and square footage tax categories while taxpayers located entirely outside the city will report only in the gross receipts category. For taxpayers reporting gross receipts and square footage, remittance of the tax will be based on the greater of the two categories.

The gross receipts tax classifications and applicable tax rates are as follows:
