Are you considering investing in Seattle’s booming real estate market?
Updated July 2026
As a first-time real estate investor, it’s important to understand the tax implications of your investments. One critical aspect to keep in mind is capital gains tax. This tax can significantly impact the profitability of your investment, so it is beneficial to understand what it is and how it applies to Seattle real estate investors. In this blog post, we’ll unpack everything you need to know about capital gains and Seattle real estate investing.
What are capital gains?
Simply put, capital gains refer to the profit you make from selling an asset. In the context of real estate, this means the difference between what you paid for a property and what you sold it for. This profit is considered taxable income, and you will need to pay capital gains taxes on it.
How does capital gains tax work for real estate investors?
Capital gains tax is split into two categories: short-term and long-term. Short-term gains apply if you hold a property for one year or less before selling it, and long-term gains apply if you hold the property for more than one year before selling it.
Short-term gains are taxed at your income tax rate, which can be as high as 37%. Long-term gains are taxed at a lower rate, with the highest being 20%. Higher earners may also owe the 3.8% net investment income tax on top of these rates. If the property was a rental, depreciation you claimed while owning it is also recaptured when you sell, taxed at a rate of up to 25%.. Washington has a state capital gains tax, but real estate sales are exempt from it under RCW 82.87.050. The state tax that does apply when you sell is the real estate excise tax (REET), which is paid at closing and uses graduated rates based on the sale price.

How does this apply to Seattle real estate investors?
Seattle’s real estate market has been on the rise for several years now, and many investors are taking advantage of the opportunity to make a profit. However, with that profit comes the responsibility to pay taxes. It’s important to understand how much of your profit will be taxed and prepare accordingly.
The good news is, there are ways to minimize the amount of capital gains tax you’ll need to pay. For example, if you hold onto a property for over a year before selling it, you’ll be eligible for the lower long-term capital gains tax rate. Additionally, if you reinvest the full sale proceeds into another investment property of equal or greater value through a qualified intermediary, you may be able to defer taxes altogether with a Section 1031 exchange.
Investing in Seattle’s real estate market can be a lucrative venture, but it’s crucial to understand the tax implications of your investments. Capital gains tax can significantly impact your profits, so it’s important to plan accordingly. With the right knowledge and preparation, you can minimize the amount of taxes you’ll need to pay and maximize your earning potential as a Seattle real estate investor.
Frequently Asked Questions
Do I have to pay Washington state capital gains tax when I sell an investment property?
No. Real estate sold directly by deed is exempt from Washington’s capital gains tax under RCW 82.87.050. Federal capital gains tax still applies to your profit, and Washington collects the real estate excise tax on the sale itself.
What taxes apply when I sell a rental property in Seattle?
A rental sale can trigger federal capital gains tax, depreciation recapture of up to 25% on the depreciation you claimed, the 3.8% net investment income tax for higher earners, and Washington’s real estate excise tax paid at closing.
How much is the real estate excise tax in Washington?
The state portion is graduated: 1.1% on the first $525,000 of the sale price, 1.28% up to $1,525,000, 2.75% up to $3,025,000, and 3% above that. Most King County cities, including Seattle, add a local rate of 0.5% on top.
Can a 1031 exchange help me avoid taxes when selling in Seattle?
A 1031 exchange defers federal capital gains tax and depreciation recapture when you reinvest the full sale proceeds into a like-kind investment property of equal or greater value through a qualified intermediary, identifying the replacement within 45 days and closing within 180 days. It does not avoid the real estate excise tax, which applies to the Washington sale regardless.
What is depreciation recapture?
Depreciation recapture is the tax owed on the depreciation deductions you claimed while owning a rental property. When you sell, that portion of your gain is taxed at a rate of up to 25% rather than the standard long-term capital gains rates.
