Washington has no state income tax and a 7% tax on large capital gains, but real estate sales and exchanges are explicitly excluded from that tax. So Washington property investors face no state income tax on rental income and no state capital gains tax when they sell.
Washington collects no income tax, which pulls in investors and high earners. In 2021 the state added a 7% tax on long-term capital gains above $270,000 a year, and the state Supreme Court upheld it in March 2023 as an excise tax rather than an income tax. Real estate was written out of that tax from the start. For a property investor, that exclusion is the detail that shapes everything else.
Washington's tax picture
No income tax
Washington does not tax individual income. Wages, salaries, rental income, interest, dividends, and business income all go untaxed at the state level, which puts Washington in a small group of states - Florida, Texas, Nevada, and a few others - with no broad-based individual income tax.
For a landlord, rental income from Washington property escapes state tax entirely. Compare that with top state income tax rates of 13.3% in California or 10.9% in New York.
The capital gains tax, and why real estate sits outside it
The 2021 tax reaches gains from the sale of stocks, bonds, and other financial assets, above a $270,000 annual threshold that is adjusted periodically. An investor who sells $500,000 in appreciated stock would owe 7% on the amount exceeding $270,000, a tax of roughly $16,100.
Real estate is excluded. The statute explicitly leaves out the sale or exchange of real property. So selling a Seattle rental for a $1 million gain triggers no Washington capital gains tax, and a 1031 exchange on Washington real estate never touches the state tax at all. The exclusion holds no matter the size of the gain: a $5 million gain on a commercial sale is excluded just the same.
Put those two facts together and the picture for real property is hard to beat: no state income tax on rental income, no state capital gains tax on the sale. The 1031 exchange then handles the federal side, deferring the 20% long-term rate, the 3.8% net investment income tax that high earners owe, and depreciation recapture on deductions taken over the years.
Investors holding both real estate and financial assets should keep the line in mind. Stock gains, cryptocurrency gains, or business-sale proceeds above $270,000 fall under the 7% tax. The real estate exclusion does not stretch to other asset classes.
Seattle and the Puget Sound market
What the tech economy does to the numbers
Seattle is one of the nation's most competitive real estate markets, and the technology sector is the anchor. Amazon, Microsoft, Google, Meta, and a deep bench of startups and mid-size firms drive employment, household formation, and rental demand across the Puget Sound.
For a 1031 investor, that demand shows up in the numbers.
Cap rates are compressed. Seattle multifamily cap rates - a property's annual net income as a share of its price - typically run 3.5% to 5.0%, among the lowest in the country, depending on class and submarket. An investor used to 6% to 7% in secondary markets will find the yields here tight.
Prices are high in absolute terms. A 20-unit building in a desirable Seattle submarket can run $8 million to $12 million, so exchange equity from a smaller market may not stretch far.
Liquidity is strong. The flip side of competitive pricing is that Seattle properties sell. Institutional investors, REITs, and private equity funds compete for assets, so a seller who needs to exit again will find buyers.
Rents have held up. Through periodic tech-sector slowdowns, Seattle's rental market has shown long-term rent growth, supported by constrained supply and continued in-migration. New construction runs into zoning, environmental review, and permitting timelines.
Key submarkets
- Capitol Hill and Central Seattle - the urban core: walkable, high-density multifamily, premium pricing.
- Ballard and Fremont - growing neighborhoods, newer construction, strong tenant demographics.
- University District - the University of Washington supplies steady tenant demand.
- South Seattle (Rainier Valley, Columbia City) - emerging neighborhoods with light rail access and rising investor interest.
- Eastside (Bellevue, Redmond, Kirkland) - proximity to Microsoft and other tech campuses drives premium rents; Bellevue's commercial market has drawn significant institutional capital.
- Tacoma and the South Sound - more affordable than Seattle, transit improving, higher yields at lower entry points.
Beyond the Puget Sound
Washington's market extends well past Seattle. Spokane, the Tri-Cities (Richland, Kennewick, Pasco), and Vancouver (Washington) offer higher cap rates and lower entry costs. These markets lack Seattle's tech-driven demand but lean on regional drivers: healthcare, agriculture, government, and logistics.
Reverse exchanges, when the property won't wait
In a market this competitive, the property you want rarely waits for you to sell what you own. A reverse 1031 exchange handles that timing problem.
Buying before you sell
In a standard exchange, you sell first, then buy. In a reverse exchange, you buy first: an Exchange Accommodation Titleholder (EAT) takes temporary title to the replacement property, and you sell your relinquished property within 180 days.
When investors reach for it
A reverse exchange tends to come up when the replacement property is unlikely to stay on the market for the 30 to 90 days a sale would take, when a competitive bid calls for demonstrated closing certainty, or when the relinquished property needs time to market while the opportunity is immediate.
Reverse exchanges cost more and carry more complexity than a standard forward exchange. The EAT must be paid, and the structure needs extra legal documentation. In a market where losing a property means starting the search over, that added cost is often justified.
Learn more about reverse exchanges.
Property taxes
Washington sets no statewide property tax rate, but counties and municipalities tax real property. Effective rates in King County, which includes Seattle, typically run 0.8% to 1.0% of assessed value, with other counties similar or a bit lower.
A 1% annual cap limits increases in total property tax collections for most taxing districts, which lends some predictability - though voter-approved levies can and do push taxes above the cap.
Investment property gets no homestead-style exemption. It is assessed and taxed at full value.
Real estate excise tax (REET)
Washington charges a Real Estate Excise Tax on property sales. The state REET is graduated:
- 1.1% on the first $525,000 of selling price
- 1.28% on the portion from $525,001 to $1,525,000
- 2.75% on the portion from $1,525,001 to $3,025,000
- 3.0% on the portion above $3,025,000
Local jurisdictions may add 0.25% to 0.50%. The seller pays REET, and it applies to the sale of the relinquished property in a 1031 exchange. Like transfer taxes elsewhere, it is a transaction cost the exchange does not defer.
Four Washington 1031 scenarios
Consolidation. A Microsoft engineer who picked up three single-family rentals over a decade rolls them into a single 12-unit apartment building in South Seattle. The exchange defers federal capital gains tax, sheds the management drag of scattered houses, and concentrates Seattle's rental demand in one professionally managed asset.
Out-of-state capital. A California investor sells a Los Angeles duplex and exchanges into a multifamily property in Tacoma, deferring both federal and California tax. Future rental income is earned in Washington, with no state income tax, rather than California's 13.3%.
Reverse exchange for a competitive buy. An investor spots an off-market 18-unit building in Capitol Hill before listing her current property. She structures a reverse exchange: the EAT acquires the Capitol Hill building, she lists and sells her relinquished property over the next four months, and the exchange closes within the 180-day window.
Move to passive ownership. A retiring Bellevue landlord sells three properties and exchanges into Delaware Statutory Trusts (DSTs), which hold industrial and multifamily assets across several states under professional management. The exchange defers federal capital gains tax, ends active management, and spreads risk across property types and geographies.
Putting a Washington exchange together
Washington's capital gains tax stays out of real estate, which leaves the federal bill as the main tax to plan around. The rest of the decision is local.
Exchange equity under $500,000 may not reach Seattle's core market, where a position from a smaller market stretches thinner; Tacoma, the South Sound, and secondary Washington markets carry lower entry costs and higher cap rates. When competing for Seattle-area properties, a reverse exchange trades a higher cost for closing certainty, weighed against the expense of losing a property to a faster buyer.
Washington's REET, local closing customs, and market rhythms reward a qualified intermediary who knows the landscape - the party that holds sale proceeds so the exchange qualifies. And REET belongs in any net-proceeds figure: the graduated rate bites on higher-value deals, with 3% on the portion above $3 million adding up quickly.

Washington's capital gains tax does not apply to real estate sales, which makes the state particularly favorable for property investors: no income tax, and no state capital gains tax on a sale. Paired with Seattle's competitive multifamily market, how those rules interact with the 1031 exchange is what the decision turns on.
Frequently asked questions
Does Washington have income tax?
No, Washington has no state income tax. It does levy a 7% tax on long-term capital gains above $270,000 a year, but real estate sales and exchanges are explicitly excluded from that tax.
Does Washington's capital gains tax apply to real estate sales?
No. The statute explicitly excludes the sale or exchange of real property, so real estate transactions fall outside the 7% tax regardless of the gain amount.
How does Washington's tax environment benefit real estate investors?
Washington has no state income tax, and its capital gains tax leaves out real estate. Together, that means no state-level tax on property sales or gains, which puts Washington among the most tax-favorable states for real estate investment.
Is Seattle a competitive market for 1031 exchanges?
Yes. Institutional investors, REITs, and private equity firms compete for Seattle multifamily, which keeps cap rates tighter than in secondary markets while making liquidity strong.
