Section 4

Supplemental Tax Bills

Supplemental taxes in Tom Green County are additional tax bills issued when property ownership changes or when new construction is completed during the tax year. These occur because Texas requires property to be taxed at its current value and ownership status as of January 1st each year. When a property changes hands or improvements are completed, a supplemental assessment captures the difference between what was originally assessed and what should have been assessed.

For example, if you purchase a home in Tom Green County in June that was previously assessed at $250,000 but now appraises at $350,000 due to improvements, you would receive a supplemental tax bill for the additional $100,000 in assessed value, prorated for the remaining months in the tax year. The calculation would be: ($100,000 ÷ 100) × your property's tax rate × (7 months ÷ 12 months). This ensures all property owners pay their fair share based on current values and ownership periods.

Escrow & Property Taxes

Most mortgage lenders in Tom Green County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly escrow payments along with your mortgage payment, typically 1/12th of your estimated annual property tax bill. The lender then pays your property taxes directly to Tom Green County when they become due. Texas property taxes are generally due by January 31st of the following year, though some jurisdictions may offer split payment options.

Lenders must provide annual escrow account statements showing all deposits, payments, and any shortages or surpluses. If property values increase significantly, you may experience escrow shortages requiring either a lump-sum payment or increased monthly payments. Property owners should verify their escrow payments match their actual tax bills, as assessment changes or exemption applications can affect the amounts due. Contact your lender immediately if you notice discrepancies between your tax notices and escrow account activity.
