How Property Tax Works

Wilson County, Texas operates under the state's property tax system to fund essential local services including schools, county operations, emergency services, and infrastructure maintenance. Property taxes are calculated by multiplying the assessed value of your property by the applicable tax rate, which varies by location within the county. The county's base tax rate for the 2025 tax year is 0.134236 per $100 of assessed value, though your total effective rate will be higher when combined with school district, municipal, and special district taxes.

Property tax rates in Wilson County vary significantly depending on your specific location within the county due to overlapping taxing jurisdictions. These may include independent school districts, municipal utility districts, emergency services districts, and other special purpose districts. Your total effective tax rate typically ranges from approximately 2.0% to 2.8% of assessed value when all taxing entities are combined. The Texas Property Tax Code governs assessment procedures, exemption eligibility, and payment requirements throughout the county.

Section 4

Supplemental Tax Bills

Supplemental taxes in Wilson County are additional property tax assessments that occur when there are significant changes to a property during the tax year. The most common triggers include new construction completion, major improvements or additions, ownership transfers that remove exemptions, or correction of assessment errors. When these events occur, the county calculates the difference between the old and new assessed values, applies the current tax rate, and prorates the additional tax based on the remaining months in the tax year.

For example, if you complete a $100,000 home addition in June and your total effective tax rate is 2.5%, the supplemental tax would be calculated as: ($100,000 × 0.025) × (7 months remaining ÷ 12 months) = $1,458. This supplemental amount would be billed separately from your regular annual property tax bill and would be due within 30 days of the assessment notice.

Escrow & Property Taxes

Most mortgage lenders in Wilson County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12 of your estimated annual property tax bill with each monthly mortgage payment, depositing these funds into an escrow account. Wilson County property taxes can be paid in four installments throughout the year: first payment due January 31st, second by April 30th, third by July 31st, and fourth by October 31st. However, many lenders choose to pay the full annual amount by the January 31st deadline to avoid multiple payment processing.

Your lender will receive tax bills directly from Wilson County and pay them on your behalf from your escrow account. Each year, your lender must provide an escrow analysis statement showing the account activity and any adjustments needed for the coming year. If your property taxes increase due to rising assessments or tax rates, your monthly escrow payment may increase accordingly. You can verify that your taxes were paid correctly by checking with the Wilson County Tax Assessor-Collector's office or reviewing your annual escrow statement from your lender.

Frequently Asked Questions

Q: When are property taxes due in Wilson County for the current tax year? A: For Tax Year 2025, property taxes can be paid in four installments: 1st payment due January 31st, 2nd payment due April 30th, 3rd payment due July 31st, and 4th payment due October 31st. You may also prepay at any time starting October 1st.

Q: What homestead exemption am I eligible for and how do I apply? A: Texas offers a $100,000 school district homestead exemption for your primary residence effective 2023. You must apply with the Wilson County Appraisal District by April 30th of the tax year. This exemption reduces your taxable value and caps annual assessment increases at 10%. Application is required and not automatic.

Q: What other tax exemptions are available and do they require applications? A: Additional exemptions include over-65 exemptions, disability exemptions, veteran exemptions, and agricultural/timber exemptions. All exemptions require separate applications filed with the Wilson County Appraisal District by April 30th deadline. Contact the appraisal district for specific eligibility requirements and application forms.

Q: How does the 10% homestead cap work? A: The homestead cap limits annual increases in your home's assessed value to 10% per year, not including new improvements. This caps assessment growth but doesn't reduce the market value. The cap applies automatically once you receive homestead exemption approval but requires the initial homestead application.

Q: When will I receive my property tax assessment and how can I appeal? A: Assessment notices are typically mailed in April-May. You have until May 31st (or within 30 days of receiving the notice) to file a protest with the Wilson County Appraisal Review Board.

Payments received after January 31st are subject to penalty fees of 6% in February, 7% in March, 8% in April, 9% in May, 10% in June, and 12% beginning in July, plus annual interest of 1% per month.

You can pay by electronic check or credit card, though credit card payments may include processing fees. The county also accepts payments by mail, phone, or in person at the tax office.

Q: Why do property tax rates vary within Wilson County? A: Your total tax rate depends on which taxing jurisdictions serve your specific property location.
