Rate Breakdown

Property taxes in Dimmit County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Dimmit County

Property taxes in Dimmit County are calculated based on your property's market value as of January 1st, which is determined annually by the Dimmit County Appraisal District (CAD). While many states utilize millage rates, Texas expresses local tax rates as a dollar amount per $100 of assessed property value. Local taxing jurisdictions—including the county, school districts, and cities—set these rates each year to fund public infrastructure, schools, and emergency services. Your final tax liability is calculated by applying these combined rates to your property's taxable value after any qualified exemptions are deducted.

Available Exemptions

Texas provides several property tax exemptions that can significantly reduce your taxable value in Dimmit County. To qualify, you must own the property and occupy it as your primary residence on January 1st of the tax year. Key exemptions include:

• Residence Homestead: Lowers the taxable valuation of your primary home for school districts and other participating local taxing units.
• Over-65 and Disability Exemptions: Provides an additional valuation reduction and establishes a school tax "ceiling," ensuring your school district taxes will not increase as long as you own and live in the home.
• Disabled Veterans: Offers graduated exemptions, up to a 100% total property tax exemption, depending on the veteran's service-connected disability rating.

Payment Schedule & Deadlines

The Dimmit County Tax Assessor-Collector distributes property tax statements annually beginning in October. Payments are due upon receipt, and the final deadline to pay your taxes in full without incurring penalties is January 31st of the following year. On February 1st, unpaid taxes officially become delinquent, immediately accruing penalty and interest charges that escalate monthly. Homeowners who are disabled, over 65, or qualifying disabled veterans can request a split-payment option, allowing them to pay their taxes in four equal installments without penalty.

Appealing Your Assessment

If you believe the Dimmit County Appraisal District has overvalued your property or applied taxes unequally, you have the right to file a formal protest. Protests must be filed with the Dimmit County Appraisal Review Board (ARB) by May 15th, or within 30 days of receiving your Notice of Appraised Value, whichever is later. Many disputes are resolved during an informal meeting with a CAD appraiser. If you cannot reach an agreement informally, you will present your evidence—such as photos of damage or sales data of comparable properties—at a formal hearing before the ARB.
