Property taxes in Texas are a frequent topic of conversation, especially for families relocating from states with high income taxes. Because Texas has no state income tax, we rely on property taxes to fund our phenomenal public schools, build local infrastructure, and keep our communities safe.
If you’re looking at luxury real estate in Fairview, Lucas, or Parker, understanding how the Collin County property tax system works is a crucial step in the home buying process. The tax rates here vary significantly depending on which city limits and school district boundaries your property falls into. A home in Lucas zoned for Lovejoy ISD will have a different tax profile than a property in Parker zoned for Plano ISD.
This guide breaks down exactly what you need to know about Collin County property tax rates in 2025 and 2026, how the Collin County homestead exemption works, and what to expect as a homeowner in these incredible Collin County suburbs.
How Collin County Property Taxes Are Calculated
Your annual property tax bill isn’t determined by a single entity. Instead, it’s a combination of rates set by several different local taxing jurisdictions. If you buy a home in Fairview, Lucas, or Parker, your total tax rate will generally consist of four main components:
-
Collin County Rate: Funds county-wide services, courts, and infrastructure.
-
Collin College Rate: Funds the Collin County Community College District.
-
City Rate: Funds municipal services like police, fire, and parks for the specific town or city.
-
School District (ISD) Rate: Funds the local public school system. This is always the largest portion of your tax bill.
To calculate your estimated property taxes, these combined rates are applied to your home’s assessed value (determined by the Collin Central Appraisal District, or CollinCAD.org) divided by 100.
2025–2026 Tax Rates: Fairview, Lucas, and Parker
Let’s look at the specific tax rates you’ll encounter in these three communities. Keep in mind that rates are expressed per $100 of assessed value.
The Baseline County Rates
No matter which of these three cities you choose, you will pay these two baseline rates:
-
Collin County: $0.149343
-
Collin College: $0.081220
City Rates
Each municipality sets its own tax rate annually based on its budget requirements:
-
City of Lucas TX property tax rate: $0.255463
-
Parker TX property tax rate: $0.310439
-
Fairview TX property tax rate: $0.316658
Lucas currently maintains the lowest municipal tax rate of the three, reflecting its slightly more rural nature and estate development zoning (such as 1.5-acre and 2-acre minimums). Parker and Fairview are only slightly higher, supporting their respective public services, parks, and expanding trail systems.
School District Rates (The Biggest Factor)
Your school district makes the most significant impact on your overall tax bill. Fairview, Lucas, and Parker are primarily served by three excellent districts:
-
Lovejoy ISD: $1.2552. Serving the majority of Lucas and Fairview, Lovejoy is consistently ranked among the top districts in the state (currently #7 best district in Texas per Niche).
-
Allen ISD: $1.1258. Serving parts of Lucas and Parker, Allen ISD is the #1 best district in Collin County according to Niche.
-
Plano ISD: $1.03955. Serving portions of Parker and a small segment of Lucas, Plano ISD offers a lower tax rate while maintaining a strong reputation for academic excellence.
Putting It All Together: Example Scenarios
To see how this impacts a homeowner, let’s build out the combined tax rates for a few common scenarios in our area:
Scenario A: A Home in Lucas Zoned for Lovejoy ISD
-
Collin County: $0.149343
-
Collin College: $0.081220

-
City of Parker: $0.310439

-
McKinney ISD (approx): $1.1043
Total Estimated Rate: 1.6515%
As you can see, the total effective tax rate typically hovers between 1.58% and 1.75%. When comparing the cost of living in Fairview TX vs McKinney TX, or Parker TX vs Allen TX, it’s vital to look at the specific school district boundaries, not just the city limits.
The Power of the Collin County Homestead Exemption
If you’re moving to Texas from California, New York, or any other state, you might be looking at that 1.7% rate and doing some quick math. But before you get sticker shock, you need to factor in the Texas homestead exemption.
A homestead exemption removes part of your home’s value from taxation, significantly lowering your overall bill. It also puts a “cap” on how much your assessed taxable value can increase each year (limited to a maximum 10% increase year-over-year).
How the Exemptions Work
For your primary residence, the State of Texas mandates a massive $100,000 exemption from your school district taxes. Because the school district makes up roughly 60% to 70% of your total bill, this represents substantial savings.
Additionally, Collin County, Collin College, and the individual cities offer their own percentage-based exemptions. For example, Collin County offers a general homestead exemption that further reduces your taxable value for their portion of the bill.
If you qualify for an Over 65 homestead exemption in Collin County or a disabled veteran exemption in Collin County, your savings increase dramatically. The Over 65 exemption typically provides an additional $60,000 to $64,000 off the school district valuation, and, most importantly, it establishes a tax “ceiling” for your school district taxes—meaning your ISD taxes will never go above the amount you pay in the year you qualify.
How to File Your Homestead Exemption in Collin County
Filing is completely free, and you should never pay a third-party company to do it for you. You apply through the Collin Central Appraisal District (CollinCAD.org).
To file, you must own the home and occupy it as your primary residence. You will need a Texas driver’s license matching the property address. The Collin County homestead exemption deadline is April 30th of the tax year, but thanks to recent changes in Texas law, you can now apply as soon as you close on your home and get your new driver’s license.
Protesting Your Property Taxes in Collin County
Because home values in Collin County have appreciated steadily over the last decade, the assessed value of your property will likely increase over time. Fortunately, Texas property owners have the right to challenge their assessed value.
The property tax protest process in Collin County happens every spring. Around April, CollinCAD sends out Notices of Appraised Value. If you believe the district has overvalued your home compared to recent neighborhood sales (often referred to as ‘comps’), you can file a protest by May 15th (or 30 days after the notice is mailed).
Many homeowners wonder how to protest property taxes in Texas effectively. The key is data. You must provide evidence that similar homes in your specific subdivision—whether that’s Ascot Heath in Fairview, Broadmoor Estates in Lucas, or King’s Crossing in Parker—sold for less than your assessed value. While you can navigate the protest process on your own, many homeowners hire local property tax consulting firms that only charge a fee if they successfully lower your bill.
