Rate Breakdown

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

How Property Tax Works in Williamson County

In Williamson County, property taxes are based on the appraised value of your property as determined by the Williamson Central Appraisal District (WCAD). The process involves:

• Assessment: WCAD evaluates your property's market value annually, considering factors like location, size, and recent sales of comparable properties.
• Tax Rates (Millage Rates): Taxing entities (e.g., county, school districts, cities) set their own rates per $100 of assessed value. For example, a rate of 2.5% means $2.50 per $100 of taxable value.
• Calculation: Your tax bill = (Appraised Value - Exemptions) × (Total Tax Rate / 100).

Tax rates vary by location within the county, so check with WCAD or local entities for precise rates.

Available Exemptions

Texas offers several property tax exemptions to reduce taxable value. Williamson County residents may qualify for:

• Homestead Exemption: Primary homeowners can deduct a portion of their home's value (e.g., $40,000 for school taxes). File with WCAD by April 30.
• Senior Citizen Exemption: Homeowners aged 65+ qualify for additional school tax reductions and may defer payments until the property is sold.
• Disability Exemption: Disabled homeowners receive similar benefits to seniors, including potential school tax freezes.
• Veteran Exemptions: Disabled veterans may qualify for partial or full exemptions based on disability rating, while surviving spouses of veterans killed in action may also receive breaks.

Apply for exemptions through WCAD with proof of eligibility (e.g., ID, disability documentation).

Payment Schedule & Deadlines

Williamson County property taxes are due annually, with the following key dates:

• Bill Issuance: Tax bills are mailed in October each year.
• Deadline: Payments are due by January 31 of the following year. Late payments incur penalties (7% in February, plus interest).

Appealing Your Assessment

If you believe your property is overvalued, follow these steps to appeal:

• File a Protest: Submit a protest form to WCAD by May 15 (or 30 days after the appraisal notice is mailed).
• Evidence: Gather proof (e.g., recent sales of comparable properties, repair estimates, or appraisal reports) to support your claim.
• Hearings: Present your case to the Appraisal Review Board (ARB), which will issue a decision.
• Further Appeals: If dissatisfied, you may file a lawsuit or request binding arbitration (for properties under $5M in value).

Consult WCAD's website or a tax professional for detailed guidance on deadlines and documentation.
