How Property Tax Works

San Augustine County's property tax system serves as the primary funding mechanism for essential local services including schools, county operations, municipal services, and various special districts. Property owners in San Augustine County pay taxes based on their property's assessed value multiplied by the applicable tax rate, which varies significantly depending on the specific taxing jurisdictions where the property is located.

The effective tax rate in San Augustine County for 2025 includes a county rate of 0.32196 per $100 of assessed value, but total rates typically range from approximately 1.5% to 2.2% when combined with school district, municipal, and special district taxes. Actual tax bills vary considerably across the county due to overlapping taxing jurisdictions such as school districts, cities, emergency services districts, and other special purpose districts that may apply additional levies to properties within their boundaries.

Section 4

Supplemental Tax Bills

Supplemental taxes in San Augustine County are triggered when property changes hands or when new construction is completed after the January 1 assessment date. These supplemental assessments ensure that property tax obligations are properly allocated between previous and new owners based on the actual ownership period during the tax year.

When a property sale occurs, the county assessor calculates a pro-rated tax amount based on the new assessed value from the date of ownership transfer through the end of the tax year. For example, if a property sells on July 1 and the new assessment increases the taxable value by $50,000, the new owner would owe supplemental taxes on that $50,000 increase for the remaining six months of the tax year. Similarly, newly completed construction projects receive supplemental assessments for the portion of the tax year following completion.

Escrow & Property Taxes

Most mortgage lenders in San Augustine County require borrowers to maintain an escrow account for property tax payments, collecting monthly installments as part of the mortgage payment. Lenders typically collect 1/12th of the estimated annual property tax bill each month, then pay the full tax bill directly to the county when due on January 31st.

Property owners should verify that their lender has current contact information and is aware of any assessment changes that might affect the tax bill. The escrow account is typically analyzed annually, and adjustments may be made to monthly payments if property values or tax rates change significantly. Homeowners can request escrow account statements from their lender and should review tax bills when received to ensure accuracy before the lender makes payment.
