How Property Tax Works

Duval County, Texas operates a property tax system that serves as the primary funding mechanism for essential local services including education, county operations, emergency services, and infrastructure maintenance. The county's property tax system is administered under the Texas Property Tax Code, with assessments based on market value as of January 1st each year. Property owners in Duval County can expect effective tax rates that vary significantly by location within the county due to different combinations of overlapping taxing jurisdictions.

The actual property tax rate you pay depends on your specific location within Duval County, as multiple taxing entities may serve your property including the county government, school districts, cities, and various special districts for services like hospitals, water, or fire protection. For the 2025-2026 fiscal year, the total county-wide tax rate is 0.869051 per $100 of assessed value, though this represents just one component of your total property tax bill. Understanding these overlapping jurisdictions and available tax credits is essential for property owners to accurately budget for their annual tax obligations.

What Makes Up Your Tax Bill

County-Wide Rate0.869051Base Duval County rate for FY 2025-2026
School DistrictVaries by districtAdditional rate for local school funding (homestead exemption of $100,000 may apply)
MunicipalVaries by cityCity services rate (if property located within city limits)
Special DistrictsVaries by districtAdditional rates for hospital districts, water districts, fire departments, etc.

Note: The 0.869051 rate shown represents the adopted county-wide rate for fiscal year 2025-2026. Your total effective tax rate will be higher when combined with school district, municipal, and special district rates that apply to your specific property location. School district rates may be reduced by the $100,000 homestead exemption for primary residences, but this exemption requires a separate application and only applies to school district taxes.

Section 3

When Are Property Taxes Due?

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

First Installment
Jan 31
Delinquent after Dec 10
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 Duval County are additional property tax assessments that occur when there are changes to property ownership, value, or use during the tax year. The most common triggers include new construction completing after the January 1st assessment date, change of ownership that removes exemptions, or completion of property improvements that increase assessed value. These supplemental taxes are calculated based on the difference between the old and new assessed values, multiplied by the applicable tax rate, and prorated for the remaining portion of the tax year.

For example, if you complete a home addition worth $50,000 in June (after the January 1st assessment date), you would receive a supplemental tax bill for the increased value covering July through December. The supplemental tax would be calculated as: ($50,000 ÷ 100) × total tax rate × (6 months ÷ 12 months). Texas Property Tax Code Section 313.025 requires that any completed application and supplemental documentation follow specific procedures, and property owners typically receive supplemental bills within 30-60 days of the triggering event.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Duval County require property tax escrow accounts for loans with less than 20% down payment, though borrowers may request to manage their own tax payments with sufficient equity. Your lender collects monthly escrow payments equal to your annual property tax bill divided by 12, plus a cushion typically equal to two months of payments. Lenders are required to conduct annual escrow analyses and adjust your monthly payment based on actual tax bills and account balance.

Property taxes in Duval County are paid in two installments: the first installment is due by October 15th, and the second installment is due by April 15th of the following year. If you have an escrow account, your lender will make these payments on your behalf and provide you with copies of the payment receipts. Property owners should verify that their lender has received the correct tax bills and is making timely payments, as you remain ultimately responsible for any unpaid taxes even when using escrow. You can verify payment status through the Duval County tax collector's office or online portal.
