Selling real estate in Washington state can generate capital gains tax liability. This calculator helps you estimate your tax obligation based on your sale price, purchase price, and holding period. Understanding Washington's capital gains tax rules is essential for maximizing your after-tax proceeds.
How Washington Capital Gains Tax Works for Real Estate
Capital gains tax applies to the profit you make when you sell an asset for more than you paid for it. For real estate in Washington state, the tax applies to the gain realized from the sale of your primary or secondary residence, investment property, or rental property.
Capital Gain Calculation
Capital Gain = Sale Price - Basis
Where Basis is the original purchase price plus any improvements, closing costs, and other capital expenditures.
Washington has a unique capital gains tax system that includes both a state income tax and a separate capital gains tax. The state income tax applies to your total income, while the capital gains tax applies specifically to your capital gains.
Holding Periods
Washington distinguishes between short-term and long-term capital gains based on how long you held the property:
- Short-term (1 year or less): Taxed as ordinary income at your marginal income tax rate
- Long-term (over 1 year): Taxed at a flat 6.5% rate (for gains over $250,000) or 0% (for gains up to $250,000)
Note: The $250,000 exemption applies to the total of all long-term capital gains in a tax year. If your gains exceed this amount, only the portion over $250,000 is taxed at 6.5%.

Exemptions and Deductions
Several exemptions and deductions can reduce your capital gains tax liability in Washington.
Standard Deductions

- Single filers: $1,250
- Married filing jointly: $2,500
Capital Loss Carryforward

Real Estate-Specific Deductions
You can deduct certain real estate expenses from your capital gain:
- Repairs and improvements
- Legal and closing costs
- Mortgage interest (up to $100,000)

Worked Examples
Example 1: Short-Term Capital Gain
You sold a property in Washington after holding it for 6 months. The sale price was $400,000, and your basis was $350,000 (including $20,000 in improvements and closing costs). Your marginal income tax rate is 9.4%.
Calculation
Capital Gain = $400,000 - $350,000 = $50,000
Capital Gains Tax = $50,000 × 9.4% = $4,700
In this case, the entire $50,000 capital gain is taxed at your marginal income tax rate of 9.4%, resulting in a capital gains tax of $4,700.
Example 2: Long-Term Capital Gain
You sold a property in Washington after holding it for 2 years. The sale price was $500,000, and your basis was $300,000 (including $50,000 in improvements and closing costs).
Calculation
Capital Gain = $500,000 - $300,000 = $200,000
Taxable Gain = $200,000 - $250,000 exemption = $0
Capital Gains Tax = $0
Since the gain is less than $250,000, no capital gains tax is due. The entire $200,000 gain is exempt from tax.
Example 3: Long-Term Capital Gain Over Exemption
You sold a property in Washington after holding it for 3 years. The sale price was $600,000, and your basis was $200,000 (including $50,000 in improvements and closing costs).
Calculation
Capital Gain = $600,000 - $200,000 = $400,000
Taxable Gain = $400,000 - $250,000 exemption = $150,000
Capital Gains Tax = $150,000 × 6.5% = $9,750
Only the portion of the gain that exceeds $250,000 is taxed at 6.5%, resulting in a capital gains tax of $9,750.
