Property Tax Protest

Meet Your North Texas Team

Resolute’s Collin County team is anchored by Brittany Harmon, who spent 13 years as a residential and commercial appraiser at the Collin Central Appraisal District before joining Resolute. Combined with David Myre’s 15 years as a Property Tax Consultant, Colby’s market knowledge, and Matt Heaton’s 10 years inside Dallas CAD, Resolute brings unmatched insider expertise to every Collin County protest.

What Collin Central Appraisal District Gets Wrong

CCAD uses mass appraisal models to value every property in the county. These models are designed for efficiency, not accuracy at the individual property level. Here’s where they consistently fall short:

Why Resolute, We’re Not an Algorithm

Collin County is one of the most contested markets in Texas. Resolute’s advantage is Brittany Harmon, a former CCAD appraiser who spent 13 years building the very valuations our clients are protesting.

1. We analyze your property individually using proprietary data and technology. Our agents build a case specific to your home and your neighborhood. No mass-processing. No cookie-cutter approaches.

2. We file all the paperwork with CCAD and schedule your hearing. You don’t touch a single form.

3. We show up for you meeting with the district on your behalf, presenting your case, and fighting for the highest reduction possible. Informal review, ARB hearing, and beyond.

4. You only pay if we save you money. No reduction, no fee. That’s our promise.

Collin County Property Tax Rates (2025)

Collin County property taxes are calculated by multiplying your property’s taxable value by the combined rate of all applicable taxing entities. Every property in Collin County is subject to multiple overlapping taxing jurisdictions including the county itself, your municipality, and your school district. Additional entities such as community colleges, hospital districts, and special districts may also apply depending on your location.

The combined tax rate for most Collin County homeowners falls approximately 1.7% to 2.2% of assessed value, depending on which entities apply to your specific property. Collin County notably has no county-wide hospital district, which is one reason combined rates are lower than Dallas or Harris County. However, properties in Municipal Utility Districts (MUDs) pay additional taxes that can add $0.85 to $1.20 per $100 on top of the standard entities. View official Collin County tax rates here.

How CCAD Calculates Your Assessed Value

The Collin Central Appraisal District (CCAD) appraises all taxable property in Collin County using a mass appraisal process. Rather than inspecting each property individually, CCAD uses statistical models to value hundreds of thousands of properties simultaneously based on comparable sales, property characteristics, and neighborhood data. Your assessed value is intended to reflect the market value of your property as of January 1 of each tax year.

Two values matter on your notice: market value and assessed value. For homesteaded properties, Texas law caps the increase in assessed value at 10% per year regardless of how much market value rises. This means a home that appreciated 20% in a given year can only see its taxable assessed value rise by 10%. Non-homesteaded properties, including investment and rental properties, carry no such cap and can be reassessed at full market value each year.

Because CCAD relies on mass appraisal models, individual property conditions, deferred maintenance, functional issues, and hyperlocal market factors are frequently missed. When your assessed value does not reflect your property’s true market value, or when comparable properties nearby are assessed lower than yours, you have grounds to protest.

Why Collin County Assessments Keep Rising

Collin County has been one of the fastest-growing counties in the United States for over a decade. Frisco, McKinney, Plano, and Prosper have all seen rapid population growth driven by corporate relocations, DFW suburb demand, and new master-planned communities. Residential values surged 31% in 2022 alone, and while growth has moderated to around 5% per year since then, the compounding effect continues to push assessed values and tax bills higher even as rates have slightly declined. For homesteaded properties, the 10% annual assessment cap provides some protection but does not prevent values from creeping upward year over year. For investment properties, rental properties, and commercial real estate with no homestead cap, the exposure is significantly greater. Protesting your assessed value annually is the only mechanism available to push back against this trend.

How to Pay Your Collin County Property Taxes

Collin County property tax bills are mailed in October each year and are due by January 31 of the following year without penalty. Scott Grigg, Collin County Tax Assessor-Collector administers tax collection for the county. Payments can be made in the following ways:

• Online: Pay at www.collincountytx.gov by credit card, debit card, or eCheck.
• By mail: Send a check payable to the Collin County Tax Assessor-Collector to the address on your tax statement.
• In person: Visit any Collin County Tax Office location. Bring your tax statement or property account number.
• Payment plans: Collin County offers installment payment options for qualifying homesteaded properties. Contact the Tax Assessor-Collector’s office for details.

Taxes not paid by January 31 accrue penalty and interest beginning February 1. By July 1, delinquent accounts are turned over to a delinquent tax attorney and additional collection fees apply. If you are waiting on the outcome of a protest, you are still responsible for paying your taxes by the deadline to avoid penalties. Any overpayment resulting from a successful protest will be refunded.
