Collin County property tax help
Think your Collin County appraisal is too high?
Collin County has some of the fastest-rising appraisals in Texas, and most homeowners never protest. You do not have to pay a firm a cut of your savings to push back. I pull the comparable sales that build a real case, and show you how to file it with CCAD yourself.
Why Collin County homeowners overpay
Fast growth means fast-rising appraisals
Collin County is one of the highest-value, fastest-growing counties in Texas, and its overall taxable value climbed again in 2025, with the sharpest jumps in growth towns like Anna, Celina, Melissa and Princeton. When values move that fast, the appraisal district is valuing tens of thousands of homes by model, and your home can easily end up above where it should sit.
A homestead exemption caps your primary home's taxable increase at 10 percent a year, which helps, but the underlying appraisal can still climb, and the cap does nothing to make sure the number is actually fair. That is what a protest is for, and in a county like Collin it is usually worth filing every year.
How it works in Collin County
Protesting with CCAD, step by step
The Collin Central Appraisal District (CCAD) sits at 250 Eldorado Parkway in McKinney and runs the whole process. Four steps, and I help with the one that decides it:
- Read your CCAD notice Each spring the Collin Central Appraisal District mails a Notice of Appraised Value. In a county where values climb this fast, that number is worth opening the day it arrives.
- File by May 15 File your protest with CCAD by May 15, or 30 days after your notice, whichever is later. Collin County lets you file online through its eProtest portal using the Owner ID and PIN printed on your notice, or you can file Comptroller Form 50-132.
- Bring the comparable sales Comparable sales and real condition issues win protests, not opinions. This is the step I help my clients with: I pull the comps for your home and your street so you show up with a case, not a complaint.
- Present it Most Collin protests settle at an informal review with a CCAD appraiser. If yours does not, you present to the Collin County Appraisal Review Board, an independent panel that issues a written order.
Deadlines and portals change year to year, so confirm the current details at collincad.org or on your notice. I'm a REALTOR®, not a tax advisor or attorney: I help with the comparable sales and the process, and for filing or legal questions I bring in the right professional. The step-by-step evidence playbook is in my guide to protesting property taxes in Texas.
The angle most people miss
You can win on unequal appraisal, not just market value
Most homeowners argue only that their market value is too high. Texas law gives you a second, quieter ground: unequal appraisal. If Collin County values your home above the median of a reasonable number of comparable properties, appropriately adjusted, you can win on fairness alone, even when the market-value number looks defensible. The appraisal district's own equity data is often the best evidence for it.
Pulling the right comparable sales and the equity comps that actually help your Collin County home is the work most owners are not set up to do, and it is exactly what I do for my clients. I walk through both grounds and the full evidence list in my Texas property tax protest guide.
The insider move
Request CCAD's evidence before your hearing
Here is a step almost no Collin County homeowner uses, and it is written into Texas law. After you file, send CCAD a written request for the data, schedules and comparables it plans to use against you at your hearing, under Tax Code Section 41.461. If the district does not deliver that information to you at least 14 days before your hearing, under Section 41.67 it generally cannot use it.
So one written request does two things at once: it lets you see the district's case in advance and prepare for it, and it can quietly bar surprise evidence if CCAD does not turn it over in time. It costs you nothing, and it is one of the biggest advantages an ordinary Collin County homeowner has. I walk through exactly how to use it, and the full evidence list, in my Texas property tax protest guide.

Common questions
Collin County property tax protest FAQ
How do I protest my property taxes in Collin County?
File a protest with the Collin Central Appraisal District (CCAD) by May 15, or 30 days after your Notice of Appraised Value, whichever is later. Collin County offers online filing through its eProtest portal at collincad.org, using the Owner ID and eFile PIN printed on your notice, or you can file Comptroller Form 50-132. Then back it up with comparable sales and any condition problems at an informal review and, if needed, a Collin County Appraisal Review Board hearing. I pull the comps for my clients so they walk in with real evidence.
When is the Collin County property tax protest deadline?
Generally May 15, or 30 days after CCAD delivered your Notice of Appraised Value, whichever is later. The 30-day clock runs from the date on your notice, so a later notice means a later deadline. The separate deadline to file a homestead exemption is April 30. Confirm the exact date on your notice or at collincad.org, since dates can shift year to year.
How do I file a Collin County appraisal protest online?
Collin Central Appraisal District accepts online protests through its eProtest / Taxpayer Portal at collincad.org. You log in with the Owner ID and eFile PIN printed on your Notice of Appraised Value, select your protest reasons, and can often upload evidence and receive a settlement offer online. Portal or website issues do not extend the deadline, so file well before May 15. I am a REALTOR®, not a tax advisor, so for filing questions I point you to CCAD directly.
Why did my Collin County appraisal go up so much?
Collin County is one of the fastest-growing, highest-value counties in Texas, so appraised values here tend to rise quickly year over year, with the county's overall value up meaningfully again in 2025 and the fastest jumps in growth towns like Anna, Celina, Melissa and Princeton. A homestead exemption caps your primary home's taxable increase at 10 percent a year, but the underlying appraisal can still climb, which is exactly why protesting most years is worth the hour.
What evidence wins a Collin County protest?
Recent comparable sales adjusted for size, age, condition and location, plus the appraisal district's own equity data showing your value sits above the median of comparable homes. Add photos of any condition problems, a contractor's repair estimate, and your closing statement if you recently bought below the appraised value. You can also request CCAD's own evidence before the hearing. The comparable sales are the part I pull for my clients.
Do I have to pay a firm to protest in Collin County?
No. Any Collin County owner can file and present their own protest and keep 100 percent of the savings. Protest firms take a share of your first-year savings or an annual fee. I pull the comparable sales and walk you through the process for free if you are my client, or for a flat $79 otherwise, with your most recent $79 credited when you buy or sell with me. You still file your own protest. I am a REALTOR®, not a tax advisor or attorney.
