Rate Breakdown

Property taxes in King County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in King County

In King County, Texas, property taxes are calculated based on the appraised value of your property and the local tax rates (millage rates) set by various taxing entities. The process begins with the King County Appraisal District (KCAD), which assesses the market value of your property annually. This assessed value is then multiplied by the combined millage rates of entities like schools, counties, and special districts to determine your tax liability.

• Assessment Process: KCAD evaluates properties using market data, property inspections, and other valuation methods. Notices are mailed to property owners each spring.
• Millage Rates: Tax rates are expressed in "mills" (1 mill = $0.001 per $1 of value). For example, a 20-mill rate on a $100,000 home would result in $2,000 in annual taxes.

Available Exemptions

Texas offers several property tax exemptions to reduce taxable value for eligible homeowners. King County residents may qualify for the following:

• Homestead Exemption: Primary residences can receive a reduction in taxable value (e.g., $40,000 for school taxes). Apply with KCAD by April 30.
• Senior Citizen Exemption: Homeowners aged 65+ may qualify for additional school tax exemptions and tax freezes.
• Disability Exemption: Disabled individuals may receive exemptions similar to seniors.
• Veteran Exemptions: Veterans with service-connected disabilities or surviving spouses may qualify for partial or full exemptions.

Submit exemption applications to KCAD with supporting documentation (e.g., proof of age, disability status, or military service).

Payment Schedule & Deadlines

King County property taxes are typically due by January 31 of the following year. Key details include:

• Payment Options: Taxes can be paid in full or in installments (check with the King County Tax Office for eligibility).
• Deadlines: Late payments incur penalties (7% in February, an additional 12% in July, and potential legal action).
• Methods: Pay online, by mail, or in person at the King County Tax Assessor-Collector’s office.

Delinquent taxes may result in liens, foreclosure, or additional fees. Seniors or disabled homeowners may defer payments under certain conditions.

Appealing Your Assessment

If you believe your property’s assessed value is incorrect, you can appeal to KCAD:

• Step 1: File a protest with KCAD by May 15 (or 30 days after receiving your appraisal notice).
• Step 2: Provide evidence (e.g., recent sales data, repair estimates, or appraisal reports) to support your claim.
• Step 3: Attend an informal meeting or formal hearing with the Appraisal Review Board (ARB).

If unsatisfied with the ARB’s decision, you may pursue further action in district court. Consult a property tax professional for guidance.
