How Property Tax Works

Dallas County, Missouri operates on a property tax system that funds essential local services including county government operations, road maintenance, schools, and various special districts. Property taxes are the primary revenue source for local governments, with the county collecting taxes on behalf of multiple taxing jurisdictions including school districts, fire protection districts, and other special service areas.

The effective property tax rate in Dallas County varies significantly by location due to the overlay of different special taxing districts. Based on current data, property owners can expect combined rates ranging from approximately 0.59% to over 1.2% of assessed value, depending on which special districts serve their property. The county assesses property at its full fair market value, and tax rates are applied to this assessed value to determine the annual tax liability.

Property tax bills in Dallas County reflect levies from multiple jurisdictions, with rates varying considerably based on your specific location within the county. Rural properties may have different service districts than those in incorporated areas, resulting in different total tax rates even for properties of similar value.

When Are Property Taxes Due?

For the 2025/2026 tax year in Dallas County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Dallas County are typically triggered by changes in property ownership, new construction, or significant improvements that increase a property's assessed value during the tax year. When these changes occur after the annual assessment date but before the end of the fiscal year, a supplemental assessment may be issued to capture the additional tax liability.

The supplemental tax is calculated as the difference between the new assessed value and the previous assessed value, multiplied by the applicable tax rate, and prorated for the remaining months in the tax year. For example, if you complete a $50,000 home addition in July and your total tax rate is 1.0%, you would owe a supplemental tax of approximately $250 (($50,000 × 1.0%) × 6/12 months remaining in the tax year).

Property owners receive separate supplemental tax bills that are due within 30 days of issuance. These supplemental assessments ensure that property tax obligations accurately reflect current property values and ownership throughout the entire tax year.

Escrow & Property Taxes

Most mortgage lenders in Dallas County require borrowers to maintain an escrow account for property taxes, especially when the loan-to-value ratio exceeds 80%. Lenders collect monthly escrow payments equal to 1/12 of your annual property tax bill plus a small cushion to account for potential increases. The lender pays your property taxes directly to Dallas County when they become due.

Property tax bills in Dallas County are typically due by January 15th each year. Lenders usually pay these taxes in late December or early January to ensure timely payment and avoid penalties. Your lender will provide an annual escrow analysis statement showing all deposits and payments made from your escrow account, along with any required adjustments to your monthly payment.

If you pay your mortgage off or refinance, you're responsible for paying property taxes directly. You can verify that taxes have been paid by contacting the Dallas County Collector's Office. Property owners who pay directly can often pay in installments, but should confirm available payment options and deadlines with the county collector.
