Washington’s Business and Occupation tax is a gross receipts tax – meaning you owe it based on total revenue, not profit. The 2026 rate changes, driven by legislative action during the 2025 session, affect multiple business classifications and have caught many small business owners off guard. Mercer Island businesses face a layered obligation: state B&O rates that have shifted, potential city-level B&O taxes from neighboring jurisdictions like Seattle and Bellevue, and eligibility thresholds for the small business B&O credit that may have changed as revenues grew. The businesses most at risk are those with mixed revenue streams, multi-city customer bases, or operations that have expanded since they last reviewed their B&O classification. Getting the recalculation right now – before quarterly estimates compound an underpayment into penalties and interest – is the priority. A six-step action plan, document checklist, and FAQ section cover everything needed to assess your current exposure and correct course heading into 2027.

Over a number of years, I worked directly with Bryn in his capacity as corporate counsel for Growers Express (Green Giant Fresh). Bryn oversaw legal matters for a number of diverse agribusinesses including a large captive insurance company. Bryn is detail oriented and very proactive when it comes to assuring the business interests he represents avoid unnecessary liability and exposure. He was a valued member of the team and worked well in a fast paced, complex environment. I highly recommend Bryn Peterson as a competent and reliable corporate counsel.
