Rate Breakdown

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

How Property Tax Works in King William County

In King William County, Virginia, property taxes are calculated based on the assessed value of your property and the current tax rate (millage rate). The County Assessor's Office determines the fair market value of all real estate and personal property, which is then assessed at 100% of market value. The Board of Supervisors sets the annual tax rate per $100 of assessed value. For example, if the millage rate is $0.75 and your home is assessed at $300,000, your annual tax would be $2,250 ($300,000 ÷ 100 × 0.75). Taxes fund local services like schools, public safety, and infrastructure.

Available Exemptions

Virginia and King William County offer several property tax exemptions to eligible residents:

• Homestead Exemption: While Virginia does not have a statewide homestead exemption, some localities may offer relief programs for primary residences.
• Senior Citizen & Disability Exemptions: Residents aged 65+ or permanently disabled may qualify for tax relief based on income and asset limits. Applications must be filed with the Commissioner of the Revenue.
• Veteran Exemptions: Disabled veterans or their surviving spouses may be eligible for partial or full exemptions depending on the disability rating (10% or higher).
