If you have spent the last few years building equity in a Seattle home or house-hacking a duplex in King County, cashing out is an exciting financial milestone. However, Washington State is home to one of the most aggressive real estate transfer taxes in the country: the Real Estate Excise Tax (REET).

Unlike property taxes (which you pay annually based on assessed value) or capital gains taxes (which you pay on your profit), the REET is a gross receipts tax on the total sale price of the property.

Before 2020, Washington utilized a flat REET rate. Today, the state uses a progressive, tiered system designed specifically to capture more revenue from high-value markets like Seattle and Bellevue. If you are planning to sell property in 2026, failing to factor the REET into your closing costs can completely destroy your projected net proceeds.

Here is exactly how the tiered REET brackets work, how local city taxes inflate the bill, and what exemptions you can leverage.

TL;DR: The 2026 Washington REET Snapshot

Tax Concept	How It Impacts Your Sale
The Tax Structure	A progressive, tiered tax. You pay higher percentages on the portion of the sale price that falls into higher brackets.
Who Pays It?	By default, the Seller pays the REET at closing.
The State Rate	Ranges from 1.10% to a massive 3.00% on the highest-priced properties.
The Local Surtax	Cities and counties add their own flat rate on top of the state rate. Seattle currently adds an extra 0.50%.
The Target	Applies to all real estate sales, including primary residences, commercial buildings, and duplexes.

1. How the Tiered State REET Brackets Work

The Washington State REET is progressive, much like federal income tax brackets. You do not pay the highest rate on the entire sale price; you only pay the higher rates on the portion of the sale price that crosses into the next tier.

While the state adjusts these thresholds periodically to account for inflation, here is the functional structure of the state-level REET brackets:

• Tier 1 (1.10%): Applies to the portion of the selling price from $0 up to $525,000.
• Tier 2 (1.28%): Applies to the portion of the selling price from $525,000.01 up to $1,525,000.
• Tier 3 (2.75%): Applies to the portion of the selling price from $1,525,000.01 up to $3,025,000.
• Tier 4 (3.00%): Applies to the portion of the selling price exceeding $3,025,000.

Because the median single-family home price in the Seattle metro area routinely sits around $800,000 to $900,000, almost every seller in the city is pushed into Tier 2. For those selling multi-family investment properties or luxury homes, Tier 3 and Tier 4 dramatically accelerate the tax burden.

2. The Local Kicker: City and County Rates

The state-level tiered rates are only the first half of the equation. Washington also allows local municipalities (cities and counties) to levy their own flat REET on top of the state tax.

• Seattle’s Local REET: The City of Seattle currently levies an additional 0.50% local REET.
• Bellevue / Kirkland: Most surrounding King County cities also levy a standard 0.50% local rate.

Crucial Note: Unlike the state tax, the local city tax is not tiered. It is a flat percentage applied to the entire gross selling price.

3. Calculating the Damage: A Seattle Example

To understand the true impact of the REET, let’s run the math on the sale of a $1,500,000 property located within Seattle city limits.

Step 1: Calculate the State Tax (Tiered)

• Tier 1: The first $525,000 is taxed at 1.10% = $5,775
• Tier 2: The remaining $975,000 is taxed at 1.28% = $12,480
• Total State REET: $18,255

Step 2: Calculate the Local Tax (Flat)

• The entire $1,500,000 is taxed at Seattle’s 0.50% local rate = $7,500

Step 3: The Grand Total

• $18,255 (State) + $7,500 (Local) = $25,755

When you close on that $1.5M property, the escrow company will automatically deduct $25,755 from your proceeds to pay the Department of Revenue before you ever see a dime. This is in addition to your real estate agent commissions and standard closing costs.

4. Entity Sales and the “Controlling Interest” Transfer

A common loophole real estate investors attempt to use is putting a property inside a Limited Liability Company (LLC) and then selling the LLC itself to the buyer, rather than selling the physical deed to the property.

Washington State is well aware of this strategy. The Department of Revenue enforces a Controlling Interest Transfer rule.

If 50% or more of the controlling interest in an entity (like an LLC or a corporation) that owns Washington real estate is transferred within a 36-month period, it triggers the REET. The tax is calculated based on the true and fair market value of the property owned by the entity, just as if the physical deed had been sold. Attempting to skirt the REET through un-reported entity transfers can result in a 50% evasion penalty.

5. Legitimate REET Exemptions

While the REET is notoriously difficult to avoid on standard sales, the state does outline a few specific, legitimate exemptions where the transfer of real estate occurs tax-free:

• Gifts: Transferring property as a genuine gift (where no money or debt assumption is exchanged) is exempt. You must file a REET Supplemental Statement to claim this.
• Inheritance: Property transferred through a will, inheritance, or community property agreement upon death is exempt.
• Divorce: Transfers of real property mandated by a court decree of dissolution of marriage or domestic partnership are exempt.
• Adding/Removing a Co-Signer: Adding a spouse to a deed, or removing a co-signer who was only on the title to help secure financing (without any money changing hands), is generally exempt.

Frequently Asked Questions

Does the buyer or the seller pay the Washington REET? By Washington state law, the seller is legally responsible for paying the Real Estate Excise Tax. The tax is automatically deducted from the seller’s proceeds at closing by the escrow or title company. However, if the seller fails to pay, the tax becomes a lien on the property, making it the buyer’s problem.

Is the Washington Real Estate Excise Tax tax-deductible? Yes. When you sell an investment property or a primary residence, the REET you paid is considered an expense of the sale. It is deducted from your gross selling price, which lowers your total capital gains, thereby reducing your federal income tax (and potentially your WA State Capital Gains Tax) liability.

Do I have to pay REET if I sell my house at a loss? Yes. The Real Estate Excise Tax is a gross receipts tax, not a capital gains tax. Even if you sell your property for less than you bought it for and take a massive financial loss on the investment, you still owe the REET based on the final selling price.
