How Property Tax Works

Culberson County, Texas operates under the state's property tax system, which serves as the primary funding mechanism for local government services, public schools, infrastructure, and emergency services. Property owners in Culberson County pay taxes based on the assessed value of their real estate, with the revenue supporting county operations, school districts, and various special purpose districts throughout the region.

The effective tax rate in Culberson County typically ranges around 1.8% of assessed value, though actual rates vary significantly by location within the county due to different combinations of taxing entities. Property owners may be subject to taxes from the county, school districts, cities, hospital districts, and other special purpose districts depending on their specific location. Texas law provides a 10% annual cap on assessment increases for homestead properties, helping to moderate tax growth for primary residences, though this protection requires filing a homestead exemption application.

Supplemental Tax Bills

Supplemental taxes in Culberson County are additional tax bills issued when property ownership changes, new construction is completed, or significant improvements are made to existing properties. These taxes represent the difference between what was originally assessed for the tax year and the new assessed value after the change in ownership or completion of construction.

For example, if you purchase a home in March that was previously assessed at $200,000 but now appraises at $250,000 due to market conditions, you would receive a supplemental tax bill for the additional $50,000 in assessed value, prorated from the date of ownership transfer through the end of the tax year. The supplemental tax would be calculated as: ($50,000 ÷ 100) × applicable tax rate × remaining months in tax year ÷ 12.

Example Calculation

Example 1: $300,000 Property with Homestead Exemption

  • Market Value: $300,000
  • School Homestead Exemption: -$100,000
  • Net Taxable Value: $200,000
  • Annual Tax (at 1.8%): $200,000 × 0.018 = $3,600
  • Monthly Escrow: ~$300

Example 2: $600,000 Property with Homestead Exemption

  • Market Value: $600,000
  • School Homestead Exemption: -$100,000
  • Net Taxable Value: $500,000
  • Annual Tax (at 1.8%): $500,000 × 0.018 = $9,000
  • Monthly Escrow: ~$750

Example 3: $1,000,000 Investment Property (No Homestead)

  • Market Value: $1,000,000
  • Exemptions Applied: $0 (investment property)
  • Net Taxable Value: $1,000,000
  • Annual Tax (at 1.8%): $1,000,000 × 0.018 = $18,000

Escrow & Property Taxes

Most mortgage lenders in Culberson County require property tax escrow accounts, where borrowers pay monthly tax installments along with their mortgage payment. Lenders collect approximately 1/12th of the annual tax bill each month, plus a small cushion to account for potential tax increases. The escrow funds are held in a separate account and used to pay property taxes when due.

Property taxes in Culberson County are typically paid annually, with the tax year running from January 1 to December 31. Lenders usually pay taxes before the January 31 deadline to avoid penalties. Property owners should verify that their lender has made timely payments and can request annual escrow account statements showing collections and disbursements. If your property taxes increase significantly due to reassessment or rate changes, your monthly escrow payment may be adjusted, and you may need to pay a shortage if the escrow account is insufficient.
