How Collin County Assesses Property

100%of market value

Assessed by: Collin Central Appraisal District

Assessment cycle: annual

Notices typically mailed: Spring (typically by mid-May)

In Texas, properties are assessed at 100% of their market value, and the tax assessed value is the figure used to calculate your property taxes. Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill. For example, if your home's market value is $496,962 (the county median), at Texas's 100% assessment ratio your assessed value would be $496,962, resulting in approximately $7,405 in annual taxes at the county's effective rate of 1.49%.

The Protest Process

Appeals are heard by the Appraisal Review Board (ARB). At the hearing, the ARB will hear arguments and review evidence from both the property owner and the appraisal district appraiser, then set a final appraisal value for the property.

Step 1: Complete a Notice of Protest Form (Form 50-132) stating your reasons for protesting the property valuation

Step 2: Prepare evidence supporting your lower value, such as comparable property sales, repair estimates, or errors in property data

Step 3: Attempt to resolve through an informal review with the appraisal district (can be done by phone, online, or in person)

Step 4: If necessary, attend a formal ARB hearing where you'll be notified 15 days in advance of the date, time and place

Step 5: If unsatisfied with the ARB decision, appeal through district court or binding arbitration

Required form: Notice of Protest Form (Form 50-132) - recommended but not required; any written protest that identifies the property and states disagreement is sufficient

Frequently Asked Questions

What is the deadline to protest my property taxes in Collin County?

The deadline to file a property tax protest in Collin County is May 15, or 30 days after your Notice of Appraised Value was mailed, whichever is later. If the deadline falls on a weekend or legal holiday, it is automatically extended to the next business day. The Collin CAD is only required to send a Notice of Appraised Value if your home's assessed value increases by over $1,000, so it's important to keep the May 31 deadline in mind in case you don't receive a notice. Missing this deadline means losing your opportunity to challenge your property's appraised value for that tax year.

How do I file a property tax protest in Collin County online?

You can file online through the Collin Central Appraisal District's Online Appeals eFile website using the secure PIN included on your Notice of Appraised Value. While the Notice of Protest form is recommended, any written protest that identifies the property, owner names, and reasons for protest is sufficient. You can also file by mail, in person, or using the 24/7 drop-box at the appraisal district office. Note that the ARB will not accept protests submitted by fax or email. The online portal is the fastest and most convenient method for filing your protest.

What is the homestead exemption worth in Collin County?

The general residence homestead exemption in Collin County provides $140,000 off the assessed value for school district property taxes. Additional exemptions include $60,000 from school district taxes for those 65 or older or disabled, plus at least $3,000 from city, county, or special district taxes. Some cities offer additional exemptions, such as Frisco's 15% homestead exemption with a $5,000 minimum. These exemptions can result in significant tax savings, potentially reducing your annual property tax bill by hundreds or thousands of dollars depending on your property value and which exemptions you qualify for.

What happens at an ARB hearing in Collin County?

Upon receiving a protest, the ARB assigns a case number and schedules a hearing, notifying you 15 days before the date, time and place. At least 14 days before the hearing, the appraisal district must send you Property Taxpayer Remedies, ARB procedures, and notify you of your right to inspect documentation they'll use. Protests are heard by three-member panels (unless single-member requested) at 250 Eldorado Parkway, McKinney, with up to 15 panels running concurrently. The panel listens to testimony and renders a decision based on evidence presented. You may participate in-person, by sworn affidavit, or by telephone/video conference if requested.

How much can I save by protesting my property taxes in Collin County?

In 2026, NTPTS clients in Collin County received an average reduction of $22,110 on their property value. With the county's effective tax rate of 1.49%, this translates to average annual tax savings of approximately $330. However, savings vary significantly based on your property's specific circumstances, the evidence you present, and whether errors exist in your property's assessment. Consistently protesting can save you thousands in property taxes over the long run by minimizing your yearly tax assessment. Even a modest reduction in your property's assessed value can result in meaningful tax savings that compound over multiple years.

What evidence do I need for a Collin County property tax protest?

You'll need to prepare evidence that supports your lower value, such as sale prices of comparable properties, property damage documentation, or inaccurate data on your Notice of Appraised Value. You can ask Collin CAD for the information they used in their assessment and review it for discrepancies or inaccuracies. All residential protests come down to adjustment calculations and comparable selection - be sure to confirm whether the comparables used are properties you would have considered purchasing. Additional evidence can include comparative market analysis, repair estimates, incorrect property record information, or misclassification of your property. The stronger and more specific your evidence, the better your chances of achieving a reduction.
