Who Sets Property Taxes in Collin County?
Collin Central Appraisal District is responsible for assessing Collin County property taxes. Your property tax bill is based in part on your home's overall appraised value. Using tax rates set by local taxing units like school districts and county commissions, the appraisal district figures your tax liability by multiplying the value of your home by the tax rate.
Since Collin Central Appraisal District is responsible for setting home values, it's also tasked with setting property taxes. You can find appraisal information for residential properties by conducting a Collin County property tax search.
Understanding Property Tax Exemptions
Qualifying Texas residents can apply for a Collin County homestead exemption to save on property taxes. Exemptions reduce the appraisal amount of your home for the purpose of determining tax liability. To qualify, you must claim ownership interest in the property, demonstrate that it's your primary residence, and reside there by January 1 of the tax year.
Texas homeowners are eligible for a $140,000 general homestead exemption on their school district's taxes. For example:
Appraised Value: $600,000
Exemption Amount: -$140,000
Taxable Value: $460,000
Other qualifying exemptions stack on top of the general homestead exemption for additional savings, and some may even result in a 100% exemption.
Over 65 or disabled: An additional $60,000 from local school district taxes
Over 65 or disabled (if offered): Minimum $3,000 from the local taxing unit
100% disabled veteran: 100% of property value
Disabled veteran with a home donated by a charitable organization: Exemption amount determined by a federal service-connected disability rating
Surviving spouse of a U.S. armed services member killed in action: 100% of property value
Surviving spouse of a first responder killed in the line of duty: 100% of property value
Farm-to-market roads or flood control (if collected): $3,000
Agricultural Valuation
You may qualify for an agricultural valuation if your residential property is used for agricultural purposes, such as soil cultivation, crop production, or livestock raising.
This isn't technically an exemption. Instead, an appraisal assesses land based on agricultural value rather than market value, which can lower your tax liability. Eligible property owners should apply between January 1 and May 1.
To qualify, you must be able to show that the land:
Is used primarily for agricultural purposes (for at least five of the past seven years or five of the last five within city limits)
Meets the county's requirements for agricultural use
Produces at the capacity required for agricultural valuation

The Property Tax Assessment Process
The residential tax assessment process in Collin County begins when the appraisal district sets property market values in January. Once property values are assessed, local entities determine tax rates based on budgetary needs.
Rates are expressed as cents on every $100 of assessed property value. For example, a home valued at $100,000 with a $0.015 tax rate owes $1,500 in property taxes annually.
During the fiscal year (October 1, 2024, to September 30, 2025), Collin County commissioners voted to maintain a tax rate of $0.149 cents per $100 of a home's value. They also voted against a new revenue tax rate to counter soaring property appraisals in Collin County.
Even though the tax rate remained unchanged, the average home appraisal increased, causing residents' tax bills to rise. Fortunately, Collin County is in Texas, which has a 10% cap on appraisal increases.
This means the county cannot raise a property's value by more than 10% in a given tax year, after accounting for any recent improvements or upgrades to the home.
To calculate your tax bill, multiply your property's appraised value, minus any homestead exemptions, by each applicable taxing entity's rate, and add the results. Alternatively, simplify the process by calculating your bill using our Collin County property tax calculator.
Example: A home valued at $500,000 with a combined tax rate of 1.49% = $500,000 x 0.0149 = $6,913 in annual property taxes.

Payment Deadlines & Penalties
Pay your property taxes on or before January 31 of the year following the tax year in question to avoid paying interest or penalties. For example, 2025 tax year payments are due by January 31, 2026. Unpaid Collin County, TX property tax begins to accrue interest on February 1.
The Property Tax Protest Process
If you disagree with your property assessment, you can file a protest and seek to lower your Texas property taxes by following these steps:
Complete a Notice of Protest Form (Form 50-132) with reasons you are protesting the property valuation and return it to the Collin Central Appraisal District online, by mail, or in person.
Provide evidence that your property's assessment is unfairly valued, including: -Comparative market analysis, repair estimates, incorrect property record information -Misclassification of property features
You can resolve the dispute with an informal appeal before the Collin County Appraisal District, which can lower your assessed value to an agreeable amount.
If you think your appraisal is still too high following an informal hearing, you can request a formal hearing before an Appraisal Review Board (ARB). The ARB will review the evidence and decide to either lower your property tax bill or stand by the appraisal from the informal hearing.
Lastly, you can appeal an unfavorable decision from an ARB in district court or through binding arbitration with a third party. You'll likely need an attorney to help with your appeal. The decision of the district court or arbitrator is final.
