The City of Kent B&O tax is a local business and occupation tax on gross receipts from commercial activity conducted within Kent city limits. Rates run from 0.1% to 0.2% depending on what your business does, and any business with $250,000 or less in annual gross receipts owes nothing. The tax applies to revenue before expenses, not profit, so it works differently from an income tax.
Who Owes the Tax
You owe Kent B&O tax if you have “nexus” with the city and your gross receipts cross the threshold. Kent City Code 3.28.030 defines nexus broadly, and a storefront in Kent is not required. Activities that establish nexus include owning or renting property in Kent, performing services there (repairs, installation, consulting, accounting, legal work), soliciting sales or delivering goods in the city, meeting with customers there, or stocking shelves at a Kent retailer. Nexus continues as long as you keep benefiting from that original contact.1Kent City Code. Kent Code 3.28 – Business and Occupation Tax
The $250,000 Threshold
Under KCC 3.28.050(C)(1), you owe no tax if your total gross receipts from all Kent business activities stay at or below $250,000 in the calendar year. Cross that line and the tax applies to all qualifying gross receipts, not just the amount over $250,000.1Kent City Code. Kent Code 3.28 – Business and Occupation Tax
Classifications and Rates
Kent groups business activities into classifications, each with its own rate. Apply the rate for each classification separately. A business that does more than one thing splits its revenue accordingly.
- 0.1% (0.001): retailing, printing, publishing, extracting for hire, processing for hire.
- 0.125% (0.00125): manufacturing, effective January 1, 2025.
- 0.2% (0.002): wholesaling, extracting, retail services, and service and other activities.
The line between “retailing” and “retail services” catches people. Selling tangible goods to consumers is retailing at 0.1%. Selling services to consumers, like landscaping, janitorial work, or hair styling, is a retail service at 0.2%.2City of Kent. City Taxes “Service and other activities” at 0.2% is the catch-all for professional services (legal, medical, consulting) and anything not covered by another classification.1Kent City Code. Kent Code 3.28 – Business and Occupation Tax Full definitions are in KCC 3.28.030.
Calculating What You Owe
Start with total gross receipts for the reporting period, sorted by classification. Subtract eligible deductions from each category. Multiply the remaining taxable amount by the rate for that classification, then add the results.
Take a Kent business that earned $400,000 in retail product sales and $100,000 in consulting fees in a quarter. Retail: $400,000 × 0.001 = $400. Consulting: $100,000 × 0.002 = $200. Quarterly tax owed: $600.
The common mistake is treating all your revenue as one classification. Because rates can differ by double, classify each transaction based on what that activity actually is, not on the overall character of your business. A metal fabricator that also runs a repair shop reports the manufacturing revenue at 0.125% and the repair revenue at 0.2%. The city’s Finance Department publishes worksheets that walk through this field by field.
Exemptions and Deductions
Two kinds of relief reduce your bill: full exemptions for certain organizations, and line-item deductions that lower taxable gross receipts.
KCC 3.28.090 fully exempts 501(c)(3) nonprofits (except on retail sales), credit unions, fraternal benefit societies on qualifying premium and dues income, nonprofit sheltered workshops, and certain congressionally chartered relief organizations. Health maintenance organizations, health care service contractors, and certified health plans are also exempt on premiums and prepayments already subject to other state taxes.1Kent City Code. Kent Code 3.28 – Business and Occupation Tax
KCC 3.28.100 allows deductions before the rate is applied. Common ones include membership dues and camping fees for nonprofit youth organizations; initiation fees, dues, and trade-show charges for nonprofit trade or professional organizations; and grants and tuition for artistic and cultural organizations. Any income earned entirely outside Kent’s city limits can be subtracted, as can returned merchandise. Keep documentation for every deduction; auditors will ask.1Kent City Code.

Filing Schedule and Payment
Most businesses file quarterly by default:
- Q1 (January–March): due April 30
- Q2 (April–June): due July 31
- Q3 (July–September): due October 31
- Q4 (October–December): due January 31
If your annual B&O liability is under $1,000 and the Tax Division approves, you can switch to annual filing, with returns due April 30 of the following year. You can also request “Active Non-Reporting” status if you’re registered but have no taxable activity. Deadlines that fall on weekends or holidays move to the next business day.2City of Kent.

Business License Comes First
Before any B&O return, you need a City of Kent business license. KCC 5.01.045 requires one for every person doing business in Kent unless specifically exempt. When you apply for the first time, the city sends a letter explaining how to file your B&O tax returns online. Apply through FileLocal or submit a paper application by mail or in person at 400 West Gowe Street, Kent, WA 98032. Separate forms exist for master business licenses, home-based businesses, and outside businesses operating in Kent without a physical location there.4City of Kent. Apply for a Business License
Late Filing and Underpayment
Kent’s penalty schedule under KCC 3.29.110 follows the state schedule at RCW 82.32.090. Penalties escalate:
- Late payment: a penalty attaches if payment isn’t received by the due date.
- Substantial underpayment: an additional penalty if the city determines you significantly underpaid.
- Operating without registration: a separate penalty, unless you register before the city notifies you.
- Failure to follow written reporting instructions from the city.
- Intent to evade: the steepest penalty, reserved for intentional evasion.
Interest also accrues on unpaid amounts. Because the percentages track the state schedule and can change, contact the Kent Tax Division at 253-856-6266 or CityTaxes@KentWA.gov for current rates.5Kent City Code. Kent City Code 3.29 – Tax Administrative Provisions
Audits and Appeals
The city can audit your B&O records going back roughly four years plus the current reporting period. Expect to produce federal income tax returns, general ledger and journal entries, purchase invoices, depreciation schedules, and documentation for every deduction or exemption claimed. Auditors focus on whether income was reported in the right classifications, whether deductions and exemptions are properly documented, and whether sales or use tax was paid on capital assets and supplies. Clean records throughout the year are the best preparation.
If the city adjusts your liability after an audit and you disagree, you can appeal to Kent’s Hearing Examiner, an independent office that reviews administrative decisions made by city officials.6Kent City Code. Office of the Hearing Examiner
