Effective January 1, 2026, Seattle raised its business-and-occupation tax threshold to $2 million in annual taxable revenue and created a separate $2 million standard deduction for businesses above the threshold.

Why it matters. No city B&O tax due does not mean no city filing. The city says businesses below the threshold must still report annual gross revenue; a Seattle business-license tax certificate remains a separate requirement.

The neighborhood test. A Columbia City retailer selling both in-store and online, or a Beacon Hill consultant serving clients across cities, should first separate Seattle receipts from other jurisdictions and reconcile them to the correct tax classification.

1. Build a defensible number. Pull your 2026 sales ledger and split Seattle receipts from other jurisdictions before estimating taxable revenue.

2. Compare the right thresholds. Check which deductions apply before comparing taxable revenue with the $2 million threshold; the standard deduction and threshold are different calculations.

3. Keep proof of compliance. Confirm your filing frequency in the city's portal and keep a dated copy of every submitted return, including zero-due filings.

Important distinction. This is a city tax change, not an exemption from Washington state B&O tax, sales tax, business licensing or other local obligations. The city's general overview still contains some older figures; rely on its 2026 change page and rules for the current threshold.

Consider a shop with sales made inside Seattle, online orders delivered elsewhere, and occasional pop-up events. A single payment processor total does not show where income is reportable. Keep invoices and destination records so the city calculation can be reconstructed if questions arise.

Do not treat a zero-due filing as an optional task. Create a simple year-end checklist: confirm license status, reconcile the sales ledger, record deductions, submit the city return, and separately review the Washington state return. Each item answers a different compliance question.

Small operators can also ask whether their bookkeeping software records gross receipts before refunds and fees. A processor deposit is not necessarily the same as gross revenue. Preserving the original transaction report makes the annual reconciliation more reliable.
