What is King County Excise Tax?
The King County Excise Tax, more formally known as the Real Estate Excise Tax (REET), is a tax imposed on the sale of real property in Washington State, including all transactions within King County. This tax is typically paid by the seller of the property and is collected by the county treasurer's office at the time of sale (recording of the deed).
The revenue generated from REET is a significant source of funding for various public services. A portion of the tax goes to the State of Washington for education, public safety, and other general fund purposes, while another portion remains with King County to fund local infrastructure, parks, and essential services.
Who Should Use This Calculator?
This King County Excise Tax calculator is an essential tool for:
- Home Sellers: To estimate their closing costs and net proceeds from a sale.
- Real Estate Agents: To provide accurate estimates to clients.
- Buyers (Indirectly): To understand the full cost of a transaction, although typically paid by the seller.
- Property Investors: For financial planning and deal analysis in the King County real estate market.
It's important to understand that REET is distinct from annual property taxes. Property taxes are levied annually based on assessed value, while REET is a one-time transaction tax applied at the point of sale.
King County Excise Tax Formula and Explanation
The calculation of King County Excise Tax involves both state and local components. Washington State imposes a tiered REET rate based on the property's sale price, while King County adds a flat percentage.
Washington State REET Rates (Tiered)
The state portion of the REET is marginal, meaning different portions of the sale price are taxed at different rates. This structure applies primarily to residential and commercial properties.
| Sale Price Range (USD) | State REET Rate |
|---|---|
| $0.01 - $525,000 | 1.10% |
| $525,000.01 - $1,525,000 | 1.28% |
| $1,525,000.01 - $3,025,000 | 1.29% |
| Over $3,025,000 | 3.00% |
Special property types like timber land and agricultural land may have different, often flat, state REET rates. For simplification in this calculator, we apply a flat 1.28% state rate for these categories, but always consult official WA DOR resources for precise calculations.
King County Local REET Rate
In addition to the state tax, King County imposes its own local REET. This rate is a flat percentage applied to the entire sale price.
- King County REET Rate: 0.25%
Total King County Excise Tax Formula
The total King County Excise Tax is the sum of the calculated State REET and the King County REET:
Total REET = (State REET based on tiers/property type) + (0.25% * Sale Price)
Variables Used in Calculation
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Sale Price | The agreed-upon price of the property. | USD ($) | $100,000 - $10,000,000+ |
| Property Type | Categorization of the property (e.g., residential, timber). | Categorical | Residential, Commercial, Timber, Agricultural |
| State REET Rate | Percentage rate applied by Washington State. | % | 1.10% - 3.00% (tiered) |
| King County REET Rate | Percentage rate applied by King County. | % | 0.25% (flat) |
Practical Examples of King County Excise Tax
Let's illustrate how the King County Excise Tax is calculated with a few real-world scenarios.
Example 1: Residential Home Sale
A homeowner sells a residential property in Seattle (King County) for $750,000.
- Property Type: Residential
- Sale Price: $750,000
Calculation:
- State REET:
- $525,000 @ 1.10% = $5,775.00
- ($750,000 - $525,000) = $225,000 @ 1.28% = $2,880.00
- Total State REET = $5,775.00 + $2,880.00 = $8,655.00
- King County REET: $750,000 * 0.25% = $1,875.00
- Total King County Excise Tax: $8,655.00 + $1,875.00 = $10,530.00
Effective Total Rate: ($10,530 / $750,000) * 100% = 1.404%
Example 2: High-Value Commercial Property Sale
A commercial building in Bellevue (King County) sells for $4,500,000.
- Property Type: Commercial
- Sale Price: $4,500,000
Calculation:
- State REET:
- $525,000 @ 1.10% = $5,775.00
- ($1,525,000 - $525,000) = $1,000,000 @ 1.28% = $12,800.00
- ($3,025,000 - $1,525,000) = $1,500,000 @ 1.29% = $19,350.00
- ($4,500,000 - $3,025,000) = $1,475,000 @ 3.00% = $44,250.00
- Total State REET = $5,775 + $12,800 + $19,350 + $44,250 = $82,175.00
- King County REET: $4,500,000 * 0.25% = $11,250.00
- Total King County Excise Tax: $82,175.00 + $11,250.00 = $93,425.00
Effective Total Rate: ($93,425 / $4,500,000) * 100% = 2.076%
Example 3: Agricultural Land Sale
A parcel of agricultural land in Enumclaw (King County) sells for $300,000.
- Property Type: Agricultural Land (simplified flat state rate for calculator)
- Sale Price: $300,000
Calculation (using simplified flat rate for state REET for this property type):
- State REET: $300,000 * 1.28% = $3,840.00
- King County REET: $300,000 * 0.25% = $750.00
- Total King County Excise Tax: $3,840.00 + $750.00 = $4,590.00
Effective Total Rate: ($4,590 / $300,000) * 100% = 1.53%
Note: Actual rates for timber and agricultural land can be more complex and may involve specific classifications or exemptions. Always verify with official sources for such specialized transactions.

Key Factors That Affect King County Excise Tax
Understanding the factors that influence the King County Excise Tax can help in better financial planning for property transactions. Here are the primary determinants:
- Sale Price (Consideration): This is the most significant factor. Higher sale prices generally result in higher REET. The tiered state rates mean that the effective tax rate increases as the sale price crosses specific thresholds (e.g., Washington State REET tiers).
- Property Type: As demonstrated, the classification of the property (residential, commercial, timber, agricultural) dictates which state REET rate structure applies. Specialized properties may have different tax treatments.
- Location within Washington State: While this calculator focuses on King County, other counties in Washington also apply the state REET. Some cities *within* King County might also have additional local taxes, though the primary King County REET is county-wide.
- Exemptions: Certain types of transfers are exempt from REET. Common exemptions include gifts, divorce settlements, transfers to heirs, or transfers to a trust without a change in beneficial ownership. Understanding these can significantly reduce or eliminate tax liability.
- Date of Sale: Excise tax rates can change over time due to legislative updates. While this calculator uses current rates, historical transactions would require applying the rates in effect at the time of sale.
- Consideration Other Than Money: If a property is exchanged for goods, services, or other property, the fair market value of the consideration received is used as the "sale price" for REET calculation, not just cash.
Always review the specific circumstances of your transaction and consult official documentation or a tax professional to ensure accurate REET calculation and compliance.

A: In Washington State, the seller of the property is typically responsible for paying the Real Estate Excise Tax (REET).
Q: Are there any exemptions from King County Excise Tax?
A: Yes, certain transfers are exempt from REET. Common exemptions include gifts, inheritance, transfers into a trust without a change of beneficial ownership, property transfers due to divorce or dissolution, and certain government transfers. It's crucial to consult the Washington State Department of Revenue for a complete list and specific requirements.
Q: How often do the King County Excise Tax rates change?

Q: What is the difference between State REET and King County REET?
A: The State REET is the portion of the tax collected by Washington State, featuring a tiered rate structure based on sale price. The King County REET is an additional, flat percentage tax collected by King County on the entire sale price, used for local services and infrastructure. Both combined make up the total property transfer tax.
Q: Can I deduct King County Excise Tax from my income taxes?
A: Real Estate Excise Tax is generally considered a closing cost for the seller. It may be added to your basis in the property for capital gains tax purposes if you are the seller, potentially reducing your taxable gain when you sell. However, it's not typically deductible as an itemized deduction for federal income tax. Consult a tax advisor for personalized advice.
Q: Does this calculator account for city-specific excise taxes within King County?
A: This calculator focuses on the state and county-wide King County REET. Some cities within King County may impose their own additional local REET for specific purposes (e.g., affordable housing). Our calculator does not currently include these city-specific taxes, so always verify if your property's specific city has an additional levy.
Q: What if I am selling timber land or agricultural land?
A: Sales of timber land and agricultural land often have different REET calculations compared to residential/commercial properties. This calculator provides a simplified estimate for these types using a flat state rate. For precise figures, especially for these specialized property types, it's highly recommended to consult the Washington State Department of Revenue or a qualified professional.
Q: How accurate is this King County Excise Tax calculator?
A: This calculator provides a close estimate based on current publicly available state and King County REET rates and typical calculation methods.
