How Property Tax Works

Webb County, Texas operates under the state's property tax system, which serves as the primary funding mechanism for local government services including schools, county operations, municipal services, and various special districts. Property taxes in Webb County fund essential services such as education, law enforcement, fire protection, road maintenance, and local infrastructure improvements. The county follows Texas Property Tax Code guidelines, with assessments based on market value as of January 1st each year.

The effective property tax rate in Webb County varies significantly by location within the county due to overlapping taxing jurisdictions. For 2025, the combined rate is approximately $0.031933 per $100 of assessed value, though property owners may pay additional rates depending on their specific municipal, school district, and special district boundaries. Actual tax bills can range from around 1.5% to over 3% of market value depending on location and applicable exemptions. Unlike some states, Texas does not provide automatic property tax relief - most exemptions and credits require annual application through the Webb County Appraisal District.

Section 4

Supplemental Tax Bills

Supplemental taxes in Webb County are additional property tax assessments that occur when there are changes in property ownership, value, or use during the tax year. The most common triggers include the sale of property to a new owner, completion of new construction or major improvements, changes in property use (such as converting agricultural land to residential), or corrections to previous assessments discovered by the Webb County Appraisal District.

When a supplemental assessment is issued, the additional tax is calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the remaining months in the tax year. For example, if a home's assessed value increases from $200,000 to $250,000 due to completed renovations in July, and the total tax rate is 2.5%, the supplemental tax would be approximately $625 (($50,000 × 0.025) × 6/12 months remaining). Supplemental tax bills are typically mailed within 30-60 days of the triggering event and have the same January 31st due date as regular property taxes, though payment plans may be available depending on the timing of the assessment.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Webb County require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders require escrow regardless of down payment amount. The lender collects monthly escrow payments equal to 1/12 of the annual property tax bill, plus homeowners insurance and any applicable mortgage insurance premiums. These funds are held in a separate escrow account and used to pay property taxes when due on January 31st each year.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected, comparing the previous year's actual tax bill to the estimated amount collected. If property taxes increase due to rising assessments or tax rate changes, the lender will adjust monthly escrow payments and may require a one-time shortage payment. Property owners can verify escrow payments by reviewing their annual escrow statement and comparing it to the actual tax bill from Webb County Tax Assessor-Collector. For properties where taxes are escrowed, the tax office mails bills to both the property owner and the mortgage servicer to ensure timely payment.

Frequently Asked Questions

Q: When are property taxes due in Webb County for the current tax year? A: Property taxes are due by January 31st each year. Webb County offers a half-payment plan where you can pay the first half by June 1st and the second half by December 1st, though this option may include additional fees.

Q: What homestead exemption am I eligible for and how do I apply? A: The primary homestead exemption provides up to $100,000 off your home's assessed value for school district taxes and caps annual assessment increases at 10%. You must apply annually with Webb County Appraisal District by April 30th. Additional exemptions may be available for seniors (over 65), disabled veterans, or disabled persons - all require separate applications.

Q: Is the homestead exemption automatic? A: No, you must file an application with Webb County Appraisal District each year by April 30th. The exemption reduces your taxable assessed value and also limits how much your assessment can increase annually (10% cap for homesteads).
