How Property Tax Works

Washington County, Mississippi operates under the state's property tax system, which funds essential county services including schools, roads, public safety, and local government operations. Property taxes in Washington County are based on an assessment rate of approximately 1% of market value, with the actual tax rate varying by location within the county due to special taxing districts and municipal boundaries.

The effective tax rate in Washington County typically ranges from 0.8% to 1.2% of assessed value, depending on your specific location and the special districts that serve your property. Areas within municipalities like Greenville may have different rates than unincorporated county areas, and properties may be subject to additional levies for school districts, drainage districts, or other special assessments. Property owners should verify their specific tax rate by checking which taxing districts apply to their parcel.

Supplemental Tax Bills

Supplemental taxes in Washington County are additional property tax bills issued when there are changes to property ownership, improvements, or corrections to the assessment during the tax year. The most common triggers include new construction completion, property sales that result in reassessment, or the addition of structures like pools, garages, or home additions.

When a supplemental assessment is issued, the tax is calculated on a pro-rated basis from the date the change occurred through the end of the current tax year. For example, if you complete a $50,000 home addition in July, you would receive a supplemental tax bill for the increased assessed value covering July through the following March (the remainder of the tax year). The supplemental tax uses the same millage rate as your regular property tax bill and is due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in Washington County require property tax escrow accounts for loans with less than 20% down payment. Your lender collects 1/12 of your estimated annual property tax with each monthly mortgage payment and holds these funds in an escrow account. The lender pays your property taxes directly to Washington County when they become due on April 1st each year.

Lenders are required to conduct an annual escrow analysis to ensure adequate funds are collected. If property taxes increase due to reassessment or rate changes, your monthly escrow payment may increase. Conversely, if taxes decrease, you may receive a refund of excess escrow funds. Property owners should review their annual escrow statements carefully and contact their lender if they notice discrepancies. You can verify that your taxes were paid correctly by checking with the Washington County Tax Collector's office or viewing your account online.
