How Property Tax Works

Sherman County, Texas operates under a property tax system that funds essential local services including schools, county operations, emergency services, and infrastructure maintenance. Property taxes in Sherman County are assessed annually based on the appraised value of real estate as of January 1st each year, with taxes becoming due on October 1st. The Sherman County Appraisal District determines property values, while various taxing entities within the county set their individual tax rates.

The effective property tax rate in Sherman County varies significantly depending on your specific location within the county, as different combinations of taxing districts apply to different areas. Based on recent data, the combined tax rate is approximately 0.50530 per $100 of assessed valuation for the 2025-2026 levy year, though this can range higher or lower depending on which school districts, municipal districts, and special purpose districts serve your property.

Section 4

Supplemental Tax Bills

Supplemental taxes in Sherman County are triggered by changes in property ownership, new construction, or improvements that increase a property's assessed value during the tax year. When these events occur after January 1st (the assessment date), the Sherman County Appraisal District may issue a supplemental assessment to capture the increased value for the current tax year.

For example, if you purchase a home in Sherman County in June that was previously exempt from taxation, or if you complete a major home addition, you may receive a supplemental tax bill. The supplemental tax is calculated by taking the difference between the new assessed value and the previous assessed value, multiplying by the applicable tax rate, and prorating for the remaining months in the tax year. If a $400,000 home receives $50,000 in improvements completed in July, the supplemental tax would be approximately $127 (assuming a 0.50530 rate): ($50,000 ÷ 100) × 0.50530 × (6 months remaining ÷ 12 months).

Escrow & Property Taxes

Most mortgage lenders in Sherman County require property tax escrow accounts for loans 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. These funds are held in a separate account and used to pay your property taxes when they become due on October 1st each year.

Lenders are required to provide annual escrow account statements showing deposits, payments, and account balances. Since Texas property taxes can fluctuate based on assessed values and tax rates, your monthly escrow payment may be adjusted annually. If your escrow account has a shortage, you may need to make up the difference through increased monthly payments or a lump sum. Conversely, if there's an overage, you may receive a refund or reduced monthly payments. Property owners can verify that their taxes were paid correctly by checking with the Sherman County Tax Assessor-Collector's office or reviewing their account online.
