Selling a House in Washington State: Do You Owe Capital Gains Tax?

When you sell a home in Washington State, understanding exactly what you owe the government can feel like a moving target. While Washington's state capital gains tax made headlines recently, the rules for real estate are entirely different.

In our latest video, Brandon Fox breaks down Washington State home-selling taxes in plain English. Here is exactly what you need to know about federal capital gains, the state's Real Estate Excise Tax (REET), and how much you will actually walk away with at closing.

Check out the full detailed video on our YouTube Channel! 

Does Washington State Charge Capital Gains Tax on Real Estate?

The short answer is no. Washington's state-level capital gains tax explicitly exempts the sale of real estate. When you sell your primary residence or an investment property in Washington, you do not owe the state capital gains tax. However, you are not entirely off the hook—you still have to navigate federal capital gains taxes and Washington's transfer tax, known as REET.

Federal Capital Gains Tax & The Home Sale Exclusion

While the state won't tax your real estate profits, the IRS might. Fortunately, the federal government provides a massive tax break for primary residences through the Section 121 exclusion:

• Single filers can exclude up to $250,000 of profit from capital gains taxes.

• Married couples filing jointly can exclude up to $500,000 of profit.

The IRS 2-Out-of-5-Year Rule

To qualify for this exclusion, you must pass the "Ownership and Use" test. This means you must have owned the home and lived in it as your primary residence for at least two of the five years immediately preceding the sale. Those two years do not have to be consecutive.

Keep Records of Your Home Improvements

Your "profit" isn't just your sale price minus your original purchase price. Major home improvements—like a new roof, a kitchen remodel, or an HVAC system—add to your home's "cost basis." A higher cost basis reduces your taxable profit. Keep your receipts; they can keep you under the $250k/$500k threshold if your home has appreciated significantly over the years.

Selling a Rental or Investment Property

The $250,000/$500,000 exclusion applies strictly to primary residences. If you are selling a rental home, a flip, or a dedicated investment property, your profits will be subject to federal capital gains taxes. You will also have to account for depreciation recapture. If you plan to sell an investment property and buy another, ask your tax professional about a 1031 exchange to defer those taxes.

Washington's Real Estate Excise Tax (REET)

Even though Washington does not charge a state capital gains tax on real estate, it does charge a Real Estate Excise Tax (REET). This is a transfer tax customarily paid by the seller at closing.

How Washington's Graduated REET Works

Washington uses a tiered, graduated rate structure for the state portion of REET. As of 2026, the tiers are:

• 1.10% on the first $525,000 of the sale 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

• 3.00% on any amount over $3,025,000

Local REET in Vancouver and Clark County

On top of the state tiers, cities and counties levy their own local REET. In Clark County and the city of Vancouver, this local add-on is typically 0.25% or 0.50% depending on the exact jurisdiction.

$700,000 Washington Home Sale Example

To see how this impacts your bottom line, let's calculate the estimated REET on a $700,000 home sale in a jurisdiction with a 0.50% local REET:

• Tier 1: 1.10% on the first $525,000 = $5,775

• Tier 2: 1.28% on the remaining $175,000 = $2,240

• State REET Subtotal: $8,015

• Local REET: 0.50% on the full $700,000 = $3,500

• Estimated Total REET Due: $11,515

Note: REET is calculated on the total sale price, not your profit or equity.

How Taxes Affect Your Estimated Net Proceeds

Your "net proceeds" are what you actually walk away with and deposit into your bank account. To calculate this, you start with your sale price and subtract:

1. Your remaining mortgage balance

2. Real estate commissions

3. Title and escrow fees

4. Prorated property taxes

5. Washington REET

Selling a home is a major financial transaction, and surprises at the closing table are never fun. Working with an experienced agent ensures you have a clear picture of your net proceeds before you even list the house.
