How Property Tax Works

Somervell County, Texas operates under the state's property tax system, which serves as the primary funding mechanism for local services including schools, county operations, emergency services, and infrastructure maintenance. Property taxes in Somervell County are collected by multiple overlapping jurisdictions, with the total effective tax rate typically ranging from 2.0% to 2.5% of assessed value, depending on your specific location within the county.

The actual tax rate you pay varies significantly based on which special taxing districts serve your property. These may include the county, school district, city (if applicable), emergency services district, and other special purpose districts. Each jurisdiction sets its own tax rate annually, and your total bill represents the sum of all applicable rates applied to your property's net taxable value after any credits or exemptions are applied.

Property values are assessed by the Somervell County Appraisal District, with Texas law limiting annual assessment increases to 10% for homestead properties. This assessment cap helps provide predictability for homeowners, though it requires filing a homestead exemption application to receive this protection.

Section 4

Supplemental Tax Bills

Supplemental taxes in Somervell County are triggered when property undergoes significant changes that affect its assessed value during the tax year. The most common triggers include change of ownership (sale/transfer), completion of new construction, or major improvements that add value to the property.

When a supplemental assessment is issued, it calculates the difference between what you've already paid based on the previous assessment and what you owe based on the new assessed value. The supplemental tax is prorated for the remaining months in the tax year from the date the change occurred. For example, if you purchase a home in July that was previously assessed at a lower value, you'll receive a supplemental bill for the increased tax amount covering July through the following January.

Example: A property sells in September for $450,000, previously assessed at $350,000. The new assessment triggers a supplemental tax on the $100,000 increase in value, prorated for September through January (5 months), at the applicable tax rate for that property's location.

Escrow & Property Taxes

Most mortgage lenders in Somervell County require borrowers to establish an escrow account for property taxes, especially for loans with less than 20% down payment. Your lender collects 1/12 of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in escrow until tax payments are due.

Property taxes in Somervell County follow a quarterly payment schedule with due dates of April 30, July 31, October 31, and January 31. However, when you have an escrow account, your lender typically pays the entire annual amount by the January 31 deadline to avoid any potential penalties. Your lender will receive the tax bill directly and handle the payment process, though you should verify the payment was made and review your annual escrow analysis statement.

If your property taxes increase due to reassessment or rate changes, your lender will adjust your monthly escrow payment accordingly, usually spreading any shortage over 12 months. You have the right to request escrow account information and can pay off any shortage in a lump sum to minimize the impact on your monthly payment.

Frequently Asked Questions

Q: When are property taxes due for the current fiscal year? A: For FY 2024-2025, taxes are due quarterly: April 30, 2024; July 31, 2024; October 31, 2024; and January 31, 2025. You can also pay the full annual amount by January 31, 2025.

Q: What tax credits are available and do they require application? A: The primary credits include the $100,000 homestead exemption for school taxes, an additional $10,000 exemption for residents 65+ or disabled, and potential disabled veteran exemptions. All credits require application - none are automatic. Applications must be filed with the Somervell County Appraisal District.

Q: How does the homestead exemption work? A: The homestead exemption provides two benefits: it reduces your taxable value by $100,000 for school district taxes, and it caps your annual assessment increases at 10%. You must file an application with the appraisal district - it's not automatic when you buy a home.

Q: When is the deadline to apply for exemptions? A: Applications for exemptions must be filed by April 30 following the tax year, though late applications may be accepted with good cause. Apply as soon as possible after purchasing a home or becoming eligible.

Q: How often are properties reassessed? A: Properties are reassessed annually by the Somervell County Appraisal District. However, homestead properties are protected by a 10% annual increase cap (requires homestead application).

Q: What are the penalties for late payment? A: Late payments incur penalties and interest. Penalties start at 6% for payments 1-30 days late, increasing to 12% for payments over 30 days late, plus annual interest charges.

Q: Can I pay property taxes online? A: Yes, Somervell County offers online payment options through the Tax Assessor-Collector's website. Credit card payments may incur convenience fees.

Q: How do special district taxes affect my bill? A: Your location determines which special districts serve your property (emergency services, hospital district, etc.). Each district adds its own rate to your total tax bill. Rural properties may have different district combinations than properties within city limits.

Q: How do I appeal my property assessment? A: File a protest with the Somervell County Appraisal Review Board by May 31 (or within 30 days of receiving your notice, whichever is later). You can protest online, by mail, or in person.

Q: What happens if I don't pay property taxes? A: Unpaid taxes become a lien on your property. After taxes become delinquent (after January 31), the county can eventually foreclose on the property to collect unpaid taxes, penalties, and interest.
