How Property Tax Works

Brazos County, Texas operates under the state's property tax system, where property taxes serve as the primary funding mechanism for local government services, schools, emergency services, and infrastructure maintenance. Property owners in Brazos County pay taxes to multiple taxing entities including the county, school districts, cities, and various special districts, resulting in a combined effective tax rate that varies significantly by location within the county.

The total property tax rate in Brazos County for FY 2025 is approximately 8.25% per $100 of assessed value, though this varies considerably depending on your specific location and the special taxing districts that serve your property. The county portion alone is 0.50%, but when combined with school district taxes, municipal taxes, and special district assessments, the effective rate can range from roughly 2.0% to 2.5% of assessed value depending on your property's location. Property taxes in Texas are assessed based on market value as of January 1st each year, with various exemptions and caps available to qualifying property owners who submit the required applications.

Section 4

Supplemental Tax Bills

Supplemental property taxes in Brazos County are additional tax bills issued when there are changes to a property's ownership, value, or tax status that occur after the initial tax roll is established. The most common triggers include ownership transfers, new construction completion, and the addition of improvements like pools, additions, or other structures that increase the property's assessed value.

When a supplemental assessment is issued, it covers the difference between the old tax amount and the new tax amount, prorated for the remaining months in the tax year. For example, if you purchase a home in June that was previously assessed at $200,000 but now appraises at $300,000, you would receive a supplemental bill covering the additional taxes on the $100,000 value increase for the remaining seven months of the tax year (June through December).

Escrow & Property Taxes

Most mortgage lenders in Brazos County require borrowers to establish an escrow account for property tax payments, collecting monthly payments along with your mortgage payment and remitting taxes directly to the tax collector. Lenders typically collect 1/12th of your estimated annual property tax bill each month, plus a cushion to account for potential increases in tax assessments or rates.

Texas law requires property taxes to be paid by January 31st annually, and lenders generally make these payments in late December or early January to ensure timely payment. Your lender will receive the tax bill directly from Brazos County and handle the payment process. It's important to review your annual escrow analysis statement to ensure adequate funds are being collected, as property values in Brazos County have been rising significantly, potentially requiring escrow adjustments to avoid shortages.
