Collin County Property Taxes and How to Protest Yours
Collin County Property Taxes and How to Protest Yours
How do you protest Collin County property taxes?
You protest Collin County property taxes by filing a formal protest with the Collin Central Appraisal District (CCAD) before the deadline printed on your appraisal notice. The Texas Comptroller says that deadline is usually May 15 or 30 days after the notice is mailed, whichever is later. For 2026 that window has closed for most owners, so the smart move now is to understand the process and prepare for the 2027 notice.
Key Takeaways
- The usual protest deadline is May 15 or 30 days after CCAD mails your notice, whichever is later, and it runs from the mailing date, not the day the notice arrives.
- An informal meeting with a CCAD appraiser does not preserve your right to a formal Appraisal Review Board (ARB) hearing, so you must file the protest first.
- Frisco's official 2026 voter-approval tax rate is $0.425517 per $100 of taxable value, but that is only the city's piece of the bill.
- Frisco's rate page lists a 2026 Collin County rate of $0.151414 per $100, and your total depends on the exact taxing units for your parcel.
- The ARB must generally give you at least 15 days' notice of your hearing, and hearings typically run May through July.
I get this question from sellers and buyers across Frisco, McKinney, Allen, and Fairview. The tax bill is part of what a home really costs to own, so it deserves the same attention as the mortgage payment. With my loan-processing background, I always look at the tax line as part of the monthly picture, not an afterthought.
What is the Collin County property tax protest deadline and timeline?
The deadline is usually May 15 or 30 days after the appraisal district mails your notice of appraised value, whichever is later. The date on your own notice controls, so find it and treat it as firm.
Here is how the standard sequence works, based on the Comptroller's protest guidance:
| Step | What happens | Timing |
|---|---|---|
| 1. Notice of appraised value | CCAD mails your notice with the stated value and protest instructions | Homesteads generally by April 1; other property May 1 or as soon after as practical |
| 2. File your protest | Use the state Form 50-132 or CCAD's e-file option | May 15 or 30 days after the notice is mailed, whichever is later |
| 3. Informal conference | Optional meeting with CCAD to try to settle the value | After the protest is filed |
| 4. ARB hearing | An independent local board hears both sides | At least 15 days' notice; typically May through July |
| 5. Decision and next steps | The ARB issues its decision, and you weigh further options | After the hearing |
What can you actually protest?
You can protest more than the dollar value. The Comptroller lists an incorrect market value, an unequal appraisal, a wrong property description, an ownership record error, an exemption decision, and other appraisal-district actions.
Separate those in your mind before you file. "My value is too high" is a different argument than "CCAD has the wrong square footage on my record."
Does meeting with a CCAD appraiser protect your hearing rights?
No. CCAD's own 2026 informal-procedure guidance states that an informal review does not preserve your right to a formal ARB hearing. File the protest by the deadline even if you plan to settle informally.
The same guidance also warns owners not to wait until after 5 p.m. on deadline day to e-file, because technical problems happen. File early and save your confirmation.
What happens at the ARB hearing?
If the informal conference does not settle things, your protest goes to the ARB, an independent board that hears disputes between owners and the appraisal district. The Comptroller's ARB page notes that hearings typically occur from May through July, though larger counties can run past July.
You should get at least 15 days' written notice with the date, time, location, and subject matter. If you still disagree after the ARB rules, the Comptroller identifies district-court appeal as one available route. That is a legal decision, so talk with a licensed professional before you go there.
What evidence works best in a Collin County property tax protest?
The strongest evidence ties your home's market value as of January 1 to facts you can document. Recent comparable sales, photos of needed repairs, and corrections to the property record carry the most weight.
Build your evidence file
- Comparable sales: homes similar in size, age, style, and condition that sold near the valuation date.
- Condition documentation: dated photos and repair estimates for deferred maintenance that CCAD's record does not reflect.
- Record corrections: wrong square footage, bedroom or bath counts, or features your home does not have.
- Builder or neighborhood comparisons: useful when you can show comparable homes appraised lower.
- Your paperwork: the notice itself, your filing confirmation, anything you upload, and any hearing notice or ARB order.
Can you protest if your value rose but similar homes sold for less?
Yes. That is a market-value or unequal-appraisal argument, and comparable sales are exactly the evidence to bring. Your specific number depends on your home's condition, location, and the sales that actually fit, and that is where a local market review helps. This is the kind of comparison I walk my clients through, since I look at these sales every day.
Check exemptions separately from value
Value and exemptions are two different levers. Confirm your property has the residence-homestead exemption, and check whether you qualify for other available exemptions, such as those tied to age or disability.
An exemption lowers your taxable value. It does not necessarily change the market value CCAD states on your notice.
How do you plan for Collin County property taxes after the protest?
Plan by reading your bill one taxing unit at a time, not by applying one countywide percentage. Your total depends on your appraised value, your exemptions, and the rates adopted by each unit that covers your parcel.
Start with the parcel, not the city name
The Comptroller's property tax basics explain that a bill can include the county, a city, a school district, Collin College, and possibly special districts. Two homes in the same city can have different combinations. Frisco, McKinney, Allen, and Fairview parcels each have their own mix, so verify yours.
Do not treat a city rate as the whole bill
Frisco's official notice lists a 2026 no-new-revenue rate of $0.418124 per $100 and a voter-approval rate of $0.425517 per $100. Those are city figures only. Frisco's property tax rate page shows a 2026 Collin County rate of $0.151414 per $100 in its rate table, and you still need the rest of your parcel's units on top of that.
If you own in McKinney, Allen, or Fairview, do not copy Frisco's numbers or last year's numbers. Verify the city and school-district rates for your exact tax unit and tax year.
Use the county estimator
Collin County's online tax estimator shows how taxing unit, property value, exemption, net taxable value, rate, and tax amount connect. Run it for your parcel instead of guessing.
Keep in mind that a lower appraised value does not always mean a proportionally lower bill. Rates, exemptions, and special-district charges can shift too. If your lender escrows your taxes, those changes can flow into your monthly payment.
Build a yearly routine
- Watch for your notice of appraised value in the spring (homesteads generally by April 1).
- Write the protest deadline on your calendar the day the notice arrives.
- Gather comparables and condition evidence early, not the week of the deadline.
- File the formal protest, then decide whether to try an informal conference.
- Review the final tax statement by taxing unit once rates are adopted.
Buying or selling? Taxes belong in the plan
If you are buying, the tax picture on a specific home matters before you write an offer. I covered the basics for newer buyers in my post on property taxes in Collin and Denton County, and the same parcel-first thinking applies in Frisco, McKinney, Allen, and Fairview. If you are selling, a clear understanding of your tax history helps you answer buyer questions with confidence. Every situation is different, and the best way to know what applies to yours is to look at your parcel together.
Tax details like these can also affect your overall budget. My first-time buyer financial prep post walks through how to think about the whole monthly picture.

FAQ
How do I protest my Collin County property taxes in 2026?
You file a protest with CCAD before the deadline on your appraisal notice, using the state Form 50-132 or CCAD's e-file option. The 2026 window has closed for most owners, so if you think you missed it, contact CCAD directly to ask about your options. Otherwise, prepare your evidence now for the next notice.
What is the deadline to protest my Frisco, McKinney, Allen, or Fairview appraisal?
The usual deadline is May 15 or 30 days after CCAD mails your notice, whichever is later. It is calculated from the mailing date, not the day the notice arrives. Your notice prints the date that applies to you.
Does meeting with a Collin CAD appraiser protect my right to an ARB hearing?
No, an informal meeting does not preserve your right to a formal ARB hearing. CCAD's own guidance says you must file the protest by the deadline even if you plan an informal review. File first, then meet.
How do homestead exemptions affect my Collin County tax bill?
A homestead exemption lowers your taxable value, which can lower your bill. It does not necessarily change the market value on your notice. Confirm it is applied to your property and check whether other exemptions, such as those tied to age or disability, may apply.
Can I appeal if the ARB's decision still feels wrong?
Possibly. The Comptroller's ARB resources point to further review after a hearing, and district court is one route the Comptroller identifies. Because that step is legal, confirm the deadlines and requirements with a licensed professional before relying on it.
The core takeaway is simple: file the formal protest on time, build your evidence around the January 1 market value, and read your bill by taxing unit. My job is to give you honest guidance on how those numbers fit into your buying or selling plans. When you are ready, schedule a complimentary consultation with me.
