On March 12, 2026, the state legislature passed SB 6346. The bill imposes a 9.9% income tax on earnings above $1 million. With that vote, Washington ended its decades-long identity as one of the only states in America with no personal income tax. Governor Ferguson signed it.
For most Washingtonians, this changes nothing. But if you own rental property in Seattle, Bellevue, or anywhere across the Puget Sound, it raises real questions. Is this tax reshaping the market you're investing in? Is it affecting the tenants you're competing for? And what does it mean for the cost of owning real estate in this region over the next decade?
The short answer is yes. However, not in the ways most headlines suggest.
Real estate is one of the few asset classes that Washington's new tax framework explicitly protects. For starters, sale proceeds are exempt from both the capital gains tax and the new Millionaires' Tax. On top of that, physical property is excluded from the 1% wealth tax on financial assets. So while stocks, bonds, and business equity face compounding tax pressure, a well-managed rental portfolio in King or Snohomish County remains one of the most tax-advantaged positions a Washington investor can hold.
With that context in mind, this guide cuts through the noise. Below, we answer the exact questions Seattle-area landlords and investors are searching for right now. We cover how the wealth tax actually works, what happens when you sell a rental property, and which strategies protect your returns in a higher-tax environment.
What Is Washington's Wealth Tax?
Washington doesn't have one single "wealth tax". Instead, it has a rapidly expanding stack of taxes on high earners and assets that, taken together, amount to the most significant tax shift in the state's history.
Here's what actually passed:
The Millionaires' Tax (SB 6346) — passed March 12, 2026 A 9.9% income tax on household income exceeding $1 million. Effective January 1, 2028, with first payments due in 2029. Framed as an excise tax on the "receipt of income" to navigate Washington's constitutional ban on a graduated income tax. A legal challenge is widely expected.
The 1% Financial Intangibles Wealth Tax — passed 2026 A 1% annual tax on stocks, bonds, mutual funds, and ETFs owned by Washington residents with holdings over $100 million. This is a true wealth tax in the classical sense — it taxes ownership, not a transaction.
Capital Gains Tax Increase — signed May 2025 Washington's existing capital gains tax was raised from 7% to 9.9% on gains exceeding $1 million, retroactive to January 1, 2025.
Property Tax Growth Cap — tripled in 2025 Local jurisdictions can now raise property tax assessments at three times the previous rate. This directly increases operating costs for every landlord in King and Snohomish Counties.
Expanded Real Estate Excise Tax (REET) Counties and some cities can now impose an additional 0.5% excise tax on real estate sales — increasing transaction costs when you sell.
Washington went from having no income tax and no capital gains tax in 2021 to having both — plus a wealth tax on financial assets — by 2026.
So the taxes are real, and they're significant. That raises an obvious follow-up question: are Washington's highest earners simply choosing to leave?
Are Millionaires Leaving Washington State?
This is one of the most searched questions about Washington's new tax environment, and the honest answer is: some are, and it's worth watching.
The most high-profile departure is former Starbucks CEO Howard Schultz, who announced he and his wife are moving from Seattle to Florida after more than four decades in the city. He didn't cite the tax in his post, but the timing was noted widely.
The concern isn't unfounded. Tax Foundation analysis found that when the Millionaires' Tax is layered with federal income taxes, Seattle's Jump Start payroll tax, and Washington's capital gains tax, top marginal rates on wage income and RSU vesting in Seattle could exceed 50% — potentially the highest in the country.
Washington has historically attracted high-earning tech executives from California specifically because of its lack of income tax. That advantage is now gone for anyone earning over $1 million.
What this means for Seattle rental property owners:
If a meaningful share of high earners relocate, it could modestly soften demand at the very top of the rental market. That said, the broader rental market rests on fundamentals that haven't changed. Amazon, Microsoft, and Boeing still anchor the regional economy. As a result, housing supply will likely continue to remain constrained. Because of this, most analysts expect the broader rental market to stay resilient despite the tax changes.
The market outlook is encouraging. But regardless of what high earners do, there are tax questions every Seattle property owner needs to understand before making any move with their portfolio. Starting with the most common one.
Do I Have to Pay Taxes If I Sell My House in Washington State?
It depends on what kind of property you're selling and how much you make from the sale. Here's a clean breakdown:
Primary Residence Washington's capital gains tax does not apply to real estate sales — including your primary home. At the federal level, the primary residence exclusion (Section 121) lets you exclude up to $250,000 in gains ($500,000 for married couples) if you've lived in the home for at least 2 of the last 5 years. Gains above that threshold are subject to federal capital gains tax.
Rental or Investment Property Washington's capital gains tax explicitly exempts all real estate sales — primary residence or investment property alike. You will not owe Washington state capital gains tax when you sell a Seattle or Bellevue rental property, no matter how large the gain.
At the federal level, investment property sales are subject to federal capital gains tax (15% or 20% depending on your income bracket), plus a 3.8% Net Investment Income Tax if your income exceeds $250,000 (married) or $200,000 (single). A 1031 exchange can defer these federal taxes — more on that below.
Real Estate Excise Tax (REET) Every Washington real estate sale (primary or investment) is subject to REET. King County's combined rate is approximately 1.78% of the sale price. On a $900,000 property, that's roughly $16,000 in transaction costs. Counties can now add an additional 0.5% under the 2026 legislation, so confirm current rates before any sale.
Does the WA State Wealth Tax Include the Sale of Rental Real Estate?
No — and this is one of the most important facts for Seattle-area landlords and investors to understand.
Washington's new taxes contain explicit exemptions for real estate at two levels:
The Millionaires' Tax (SB 6346): Real estate sales are statutorily excluded from the tax base. Even if a property sale generates millions in proceeds, those proceeds do not count toward the $1 million income threshold.
Washington's Capital Gains Tax: Real estate sales have been exempt since the tax was first enacted in 2022. That exemption survived the 2025 rate increase and remains intact.
The 1% Financial Intangibles Wealth Tax: Applies exclusively to financial intangible assets — stocks, bonds, mutual funds, ETFs. Physical real estate is not a financial intangible and is not subject to this tax.
The bottom line: among the major asset classes in Washington, real estate is the most comprehensively protected from the state's new and expanding tax framework. Investors holding appreciated Seattle or Bellevue properties can sell without triggering Washington's capital gains tax or the Millionaires' Tax. Investors holding appreciated stock portfolios of the same value face both.
How to Avoid Capital Gains on Real Estate in Washington State
Since Washington already exempts real estate sales from its capital gains tax, the strategies here are primarily about minimizing federal capital gains exposure. These are the most effective tools available to Seattle-area investors.
1031 Exchange A 1031 exchange allows you to sell an investment property and reinvest the proceeds into a like-kind property, deferring federal capital gains taxes indefinitely. There are strict timelines: you must identify a replacement property within 45 days of the sale and close within 180 days. Many Puget Sound investors use this strategy to trade single-family rentals in Seattle for small multi-family properties in Bellevue, Everett, or Renton without triggering a tax event.
Primary Residence Exclusion (Section 121) If a property was your primary residence for at least 2 of the last 5 years, you can exclude up to $250,000 in federal capital gains ($500,000 if married). This applies even if you rented the property after moving out, subject to limitations.
Installment Sales Rather than receiving the full sale price in one year, an installment sale spreads payments, and the resulting gains, across multiple tax years. This can keep annual gains below thresholds that trigger higher federal rates or the Net Investment Income Tax.
Cost Segregation and Depreciation While not a capital gains strategy at the point of sale, cost segregation studies accelerate depreciation deductions during ownership — often generating $70,000–$150,000 in additional first-year deductions for typical Seattle-area properties. This reduces taxable rental income during your holding period. Note that depreciation taken during ownership is subject to recapture at sale under federal rules.
Opportunity Zone Investments If you reinvest gains into a Qualified Opportunity Zone fund, you can defer and potentially reduce federal capital gains taxes. There are Opportunity Zones in parts of King and Snohomish Counties.
Always consult a Washington-licensed CPA before executing any of these strategies. Rules and timelines are strict, and the interaction between federal and state tax treatment can be complex.
What Is the 6-Year Rule Exemption?
The "6-year rule" is an Australian tax concept that frequently appears in U.S. real estate searches — it does not exist in Washington State or federal U.S. tax law.
In Australia, the 6-year rule allows homeowners to rent out their former primary residence for up to six years while still claiming it as their main residence for capital gains tax purposes. There is no equivalent provision in Washington State or at the federal level.
The closest U.S. equivalent is the 2-of-5-year primary residence rule (Section 121):
To claim the federal primary residence capital gains exclusion ($250,000 / $500,000 for married couples), you must have lived in the home as your primary residence for at least 2 of the last 5 years before the sale. This means you can rent out a former primary residence for up to 3 years after moving out and still potentially qualify for the exclusion — as long as you lived there for 2 years within that 5-year window.
Example: You lived in your Seattle home from 2019 to 2023, then rented it out. If you sell in 2026, you still fall within the 5-year window and can claim the exclusion on up to $250,000 ($500,000 married) of gains — because you lived there for 2 of the last 5 years.
If you wait too long after moving out, you lose eligibility. The clock starts from the date of sale and looks back 5 years. If you can't show 2 years of primary residence within that window, the full gain is subject to federal capital gains tax.
What This Means for Seattle, Bellevue & Puget Sound Landlords
The tax changes create both headwinds and tailwinds for Puget Sound property owners.
The headwinds:
- Property taxes can now rise faster due to the tripled growth cap — expect higher annual operating costs across King and Snohomish Counties
- REET expansion increases transaction costs when selling
- High-earning tenants may weigh relocation, potentially softening demand at the top of the market
- If your total household income exceeds $1 million (rental income included), the Millionaires' Tax will affect you starting 2028
The tailwinds:
- Real estate remains explicitly exempt from Washington's capital gains tax and Millionaires' Tax at the point of sale
- As financial assets face heavier taxation, real property becomes relatively more attractive as a capital deployment vehicle
- The Eastside rental market is being actively strengthened by tech return-to-office mandates at Amazon, Microsoft, and others
- The estate tax "grand bargain", which reduced the top estate tax rate from 35% to 20%, eases succession planning for multi-property owners
The bottom line for landlords: Your operating costs are going up. Your sale exemptions are intact. The investors who will be best protected are those who maximize net operating income through optimal rent pricing, minimal vacancy, and deductible professional management.
How SJA Helps Investors Protect Returns in a Higher-Tax Environment
When operating costs rise and margins tighten, the difference between a self-managed property and a professionally managed one shows up directly on your bottom line.
SJA Property Management has served Seattle, Bellevue, and Puget Sound property owners for 16 years. Here’s how we help investors adapt to the current environment:
Rent optimization: We continuously monitor pricing across Seattle neighborhoods, the Eastside tech corridor, and Puget Sound submarkets to ensure your property commands market rate. Many self-managed owners leave 5–15% in rental income on the table.
Vacancy reduction: Our 30-Day Lease Guarantee backs this up — if we can’t place a qualified tenant within 30 days, we waive your first month’s management fee.
Deductible management fees: Property management fees are fully deductible operating expenses against rental income. In many cases, the tax deduction partially offsets the cost of management itself.
Legal compliance: Washington’s landlord-tenant laws are evolving alongside its tax code — from Just Cause Eviction requirements to landlord notice rules. We track every change so you don’t have to.
