Washington Tax Guide for High Earners book cover with mountain and eagle artwork

Summary

Washington's new 9.9% income tax on earners above $1 million takes effect in 2028. This practical guide by tax attorney Joe Wallin covers exactly what high earners, founders, and investors need to do — and when — to protect their wealth before the deadline.

Washington is no longer a no-income-tax state. A new 9.9% tax on household income above $1 million takes effect in 2028 — and for founders, investors, and high earners, the decisions you make before that deadline could save you hundreds of thousands of dollars.

This guide — written by startup and tax attorney Joe Wallin (NYU LL.M. in Taxation, 25+ years advising founders and investors) — gives you a practical, plain-English roadmap for exactly what to do before 2028. Whether you're a founder sitting on QSBS, an executive with a large income event on the horizon, or an advisor counseling Washington clients, this is the guide you need right now.

$49.99 — Digital edition with ongoing updates as the law evolves.
