Washington’s Millionaires Tax Is Forcing Wealthy Buyers to Rethink Property Choices

Washington’s new wealth levy and what it means for real estate USA

Washington state has approved a so-called "millionaires tax" that is already altering how high-net-worth individuals and their advisers approach the real estate market. The measure imposes a 9.9% tax on annual income above $1 million, with implementation expected in 2028 if it survives court challenges. While this policy affects a small share of households — roughly 0.5% of the population — those households help set pricing and demand in the luxury and investment segments of the housing market.

I have spoken with brokers and agents who say some clients are treating the law as a new cost of doing business, while others are accelerating moves, sales and investment plans. For buyers, sellers and investors focused on real estate USA, the law is an immediate reason to revisit tax planning, timing and destination markets.

How the tax is structured and who it hits

The headline numbers are simple to state but the real impact is complex. Key points:

• The tax is 9.9% on income above $1 million per year.
• Implementation is expected in 2028, pending legal challenges.
• The measure will affect roughly 0.5% of Washington residents, a small share of households but an outsized share of luxury transactions.
• Washington already has capital gains rules that tax long-term gains with a 7% rate and a 2.9% surtax on gains exceeding $1 million in a calendar year.

A critical carve-out for real estate markets: proceeds from the sale of a primary residence are largely exempt, a result of lobbying from real estate associations. Agents tell me that this exemption is central to calming sellers who feared an additional tax on home sales.

Immediate market signals: timing, second homes and exits

Brokers in the Seattle area report two clear behavioral responses among wealthy clients:

• Some are accepting the tax as a public policy shift and holding to prior plans. They are more likely to reorganize income streams, rely on tax advisors, or use planning tools.
• Others are accelerating timelines for relocation or asset sales. Clients who were planning to leave Washington in five to ten years are now compressing that schedule to three years or less.

Jacob Weaver, a managing broker in Bellevue, told HousingWire that clients are splitting into these two groups. He said many high-net-worth individuals earn through business structures, investments and real estate, not simple salaries, and they have access to sophisticated advisors. That makes their responses varied and sometimes quick.

Agents are also seeing increased interest in second-home markets with friendlier tax environments. Destinations mentioned by multiple brokers include:

• Nevada (Las Vegas, Henderson)
• Florida
• Arizona (greater Phoenix area)
• Palm Springs area in California

These markets are attracting buyers who want a primary or secondary residence outside Washington’s tax reach. Developers in Nevada are building luxury condos and single-family projects tailored to that demand.

What this means for luxury housing and pricing dynamics

Luxury listings are sensitive to changes in the wallet of their typical buyer. Because the millionaires tax affects the incomes of people who often buy or invest above $1 million, we are likely to see a shift in demand and possibly pricing at the top of the market.

Short-term observations from brokers:

• Business has remained relatively stable so far in the $1 million to $2 million band; agents report multiple offers in that range.
• Some sellers who were ready to move are accelerating listing schedules, which could add supply to the upper end.
• A possible "laddering" effect is in play: a cooling in higher-price tiers might open opportunities for buyers who previously could not access that range.

I will be blunt: a policy that makes wealthy residents reassess domicile choices makes the upper end of the market less insulated. If more high-income households shift residency out of Washington, demand for new luxury builds and bespoke estates could ease, which would put downward pressure on prices for those assets over time. That does not mean an immediate crash; it does mean slower growth or targeted sell-offs in specific neighborhoods.

Capital gains, primary residences and the role of tax lobbying

Washington’s real estate associations have scored a significant win: primary residences remain largely exempt from the new tax regime. That exemption is important because it preserves the traditional residential sales market for homeowners who buy and sell their main home.

At the same time, investors and serial sellers are still exposed to capital gains provisions. Washington’s existing capital gains framework taxes long-term gains at 7% plus a 2.9% surtax on gains over $1 million. Those combined costs, together with the millionaires tax on ordinary income, increase the overall tax drag on high-value transactions.

What that means in practice: sellers of investment properties, developers flipping lots and business owners selling companies will need to coordinate multi-disciplinary advice from:

• Certified public accountants focused on high-net-worth taxation
• Real estate attorneys for transaction structuring
• Brokers who understand timing and market absorption

Those conversations are already happening in Seattle offices and Bellevue boardrooms.

Practical strategies agents and investors are using now

Agents I interviewed describe advising clients on several concrete actions. These are not legal tips but common strategies in their playbooks:

• Review residency and domicile plans early. For clients already planning a move, closing the loop on domicile now can change state tax exposure.
• Revisit timing for company sales and liquidity events. Sellers who anticipate a large taxable event are talking to tax advisers about timing and structure.
• Consider second-home or investment markets in states with no personal income tax. Nevada, Florida and Arizona top the list for Washington buyers.
• Use tax-deferred strategies where eligible. For investment-property owners, tools such as 1031 exchanges remain part of the discussion for deferring taxable gain on qualified properties, though rules and eligibility should be checked with counsel.
• Maintain liquidity and flexibility.
