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

Understanding property taxes in Harris County, Texas, can seem complex, but familiarizing yourself with the core principles, available exemptions, payment processes, and your rights as a homeowner can empower you. This guide will walk you through the essentials of how property taxes are calculated, how you might reduce your taxable burden, and what to do if you disagree with your appraisal.

How Property Tax Works in Harris County

Property taxes in Harris County are ad valorem taxes, meaning they are based on the value of your property. The Harris Central Appraisal District (HCAD) is responsible for appraising all taxable property in the county at market value as of January 1st each year. Your appraised value, less any applicable exemptions, becomes your taxable value. Multiple taxing units – including the county, your city, school districts, and various special districts (like hospital or community college districts) – then adopt their own tax rates, often expressed as a specific dollar amount per $100 of taxable value. Your total property tax bill is the sum of the taxes levied by each of these taxing entities on your property's taxable value.

Available Exemptions

Texas law provides several exemptions that can significantly reduce the taxable value of your property, thereby lowering your tax bill. To apply for most exemptions, you typically file an application with HCAD.

• Homestead Exemption: Reduces the taxable value of your primary residence. All Texas homeowners are entitled to a general homestead exemption from their school district, and many local taxing units also offer one.
• Over-65 or Disabled Person Exemption: If you are over 65 or disabled, you qualify for an additional homestead exemption from your school district, along with a tax ceiling on your school taxes. Many local taxing units also provide additional exemptions.
• Disabled Veteran Exemption: Veterans with a service-connected disability are eligible for exemptions ranging from $5,000 to $12,000 off their property value, depending on their disability rating. Veterans with a 100% service-connected disability may qualify for a full exemption of the total appraised value of their homestead.

Payment Schedule & Deadlines

Property tax bills are typically mailed by the Harris County Tax Assessor-Collector in October each year. Payments are due by January 31st of the following year. If January 31st falls on a weekend or holiday, the deadline is extended to the next business day. Failure to pay on time will result in penalties and interest accruing on the unpaid balance. For homestead properties, taxpayers often have the option to pay their property taxes in four equal installments, with deadlines on January 31, March 31, May 31, and July 31. This option must be elected by the first payment due date.

Appealing Your Assessment

As a property owner, you have the right to protest your property’s appraised value or other appraisal decisions made by HCAD if you believe they are incorrect. The deadline to file a protest is typically May 15th, or 30 days after HCAD mails your Notice of Appraised Value, whichever is later. The protest process usually involves an informal review with an HCAD appraiser to discuss your concerns and present evidence. If an agreement isn't reached, you can proceed to a formal hearing before the Appraisal Review Board (ARB), an independent panel that will hear both your evidence and HCAD’s. Providing strong evidence, such as comparable sales of similar properties in your area, photos of needed repairs, or independent appraisals, is crucial for a successful appeal.
