How Property Tax Works

Blanco County, Texas operates under the state's property tax system, which serves as the primary funding mechanism for essential local services including schools, county operations, emergency services, and infrastructure maintenance. Property taxes in Blanco County are assessed based on the market value of real estate as of January 1st each year, with various taxing entities including the county, school districts, and special districts each levying their own rates.

The effective property tax rate in Blanco County varies significantly by location within the county due to different combinations of taxing districts. For FY 2025-2026, property owners can expect total effective rates ranging from approximately 1.5% to 2.2% of assessed value, depending on which school district, municipal, and special taxing districts serve their property.

Supplemental Tax Bills

Supplemental taxes in Blanco County are additional assessments that occur when there are changes to a property's assessed value during the tax year. Common triggers include new construction completion, major improvements, ownership transfers, or corrections to assessment errors. When supplemental taxes are levied, they are calculated on a pro-rated basis from the date the change became effective through the end of the current tax year.

For example, if a homeowner completes a $100,000 addition to their home in July, and the improvement is assessed and added to the tax roll in August, they would receive a supplemental tax bill covering August through December (5 months). The supplemental tax would be calculated as: ($100,000 × applicable tax rate ÷ 12 months × 5 months). Property owners typically receive supplemental tax bills separately from their annual tax statement, with their own specific due dates.

Escrow & Property Taxes

Most mortgage lenders in Blanco County require property tax escrow accounts for borrowers with less than 20% down payment, though some borrowers may opt into escrow for convenience. Lenders collect monthly property tax payments along with principal, interest, and insurance, depositing these funds into an escrow account. The lender then pays property taxes directly to Blanco County when due, typically by the January 31st deadline.

Escrow accounts are analyzed annually, and lenders may adjust monthly payments if tax assessments change significantly. Property owners should verify that their lender has current exemption information and correct property details to ensure accurate escrow calculations. When property taxes increase due to rising assessments or rate changes, borrowers may face escrow shortages requiring either a lump sum payment or increased monthly payments to rebuild the account balance.
