The Allen, Texas property tax rate is roughly $1.7718 per $100 of taxable value for 2025–2026, combining what four separate taxing entities charge on the same property. On a home with $400,000 in taxable value, that works out to about $7,087 a year. Your actual bill depends on both that combined rate and the value the Collin Central Appraisal District puts on your home, minus any exemptions you qualify for.
The Four Rates Behind Your Bill
Allen homeowners pay one bill, but four jurisdictions each set their own piece of it. The Collin County Tax Assessor-Collector adds them together and sends a single statement. For the current tax year, the rates per $100 of taxable value are:1City of Allen. Taxes
- Allen Independent School District: $1.1258, about 64 percent of the total.
- City of Allen: $0.4154, covering municipal operations, police and fire, parks, and debt service. The city council trimmed this rate slightly for the current fiscal year.2City of Allen. City Budget, Tax Rate Approved for FY 25-26
- Collin County: $0.149343, funding courts, the district attorney, regional roads, and county law enforcement.
- Collin County Community College: $0.08122, for Collin College programs and campuses.
Each governing body adopts its own rate every year after public hearings and budget review. The numbers above are current, but they shift annually.
How Your Tax Bill Is Calculated
The Collin Central Appraisal District (CCAD) sets a market value for every property each year, and that number is where your bill starts.3Collin Central Appraisal District.

Taxpayer Portal
If the home is your primary residence, state law caps how fast its appraised value can rise. CCAD cannot raise your homestead’s appraised value by more than 10 percent per year above the prior year’s appraised value, plus the value of any new improvements.5State of Texas. Texas Tax Code 23.23 – Limitation on Appraised Value of Residence Homestead In years when the market jumps, this cap can keep your taxable value well below what the home would actually sell for.
From there, exemptions come off the top, and the combined rate is applied to what remains. A home appraised at $500,000 with the $140,000 school homestead exemption would be taxed by Allen ISD on $360,000, while the city, county, and college rates apply to the appraised value minus any exemptions those entities offer.
Exemptions That Lower What You Owe
Residence Homestead
If you own and occupy the home as your principal residence, you qualify for a residence homestead exemption. Allen ISD must exempt $140,000 of appraised value before applying the school rate.6Texas Comptroller of Public Accounts. Property Tax Exemptions Other taxing units may adopt a local-option exemption of up to 20 percent of appraised value, with a floor of $5,000.
To claim it, file Form 50-114 with CCAD along with a copy of your Texas driver’s license or state ID showing the property address.7Collin Central Appraisal District. How Do I Apply for Exemptions? You apply once and it stays in place unless your circumstances change.
Over-65 and Disability
Homeowners who are 65 or older get an extra $60,000 exemption from school taxes on top of the standard homestead. Disabled homeowners receive the same additional $60,000 school exemption. Cities, the county, and other taxing units may also offer additional exemptions of at least $3,000 for seniors and disabled homeowners.
The over-65 exemption also brings a school tax ceiling. The dollar amount of school taxes you pay in the first year you qualify becomes the most you will ever owe in school taxes on that home.8State of Texas. Texas Tax Code 11.26 – Limitation of School Tax Your bill can drop in a year when rates fall, but it cannot climb above that ceiling, no matter how much the property’s value rises.
Disabled Veteran
Veterans with a service-connected disability rating receive exemptions that scale with the severity of the rating. A 100-percent disability rating, or a total disability rating for individual unemployability, exempts the entire property value from taxation. Surviving spouses of qualifying veterans may also be eligible. You will need documentation from the U.S. Department of Veterans Affairs confirming the rating when you apply.
How to Protest Your Appraisal
If CCAD’s number looks too high, challenge it. Filing a protest costs nothing and is the most direct way to bring your bill down. Many Allen homeowners treat the appraisal notice as the final word. It isn’t.
You must file a written notice of protest by May 15 or within 30 days of the date CCAD mailed your notice of appraised value, whichever is later.9State of Texas. Texas Tax Code 41.44 – Notice of Protest You can file online through the CCAD Taxpayer Portal using the owner ID and eFile PIN on your appraisal notice, or submit Form 50-132 on paper.10Texas Comptroller of Public Accounts. Appraisal Protests and Appeals
The strongest evidence is recent sales of comparable homes near yours: properties sold within the past year that match on size, age, lot, and condition. Where they differ, be ready to explain why those differences justify a lower value for yours. Also pull up CCAD’s record for your property and check the basics. Wrong square footage, an incorrect bedroom count, or a misclassified property type inflate values more often than owners expect.
Most protests begin with an informal meeting with an appraiser, and many settle there with a negotiated value. If you can’t agree, the case moves to a formal hearing before the Appraisal Review Board, where you and the appraisal district each present evidence to a panel. Hearings run about 15 to 20 minutes, and you can appear in person, by phone or video, or by written affidavit.
Paying Your Taxes
The Collin County Tax Assessor-Collector’s office bills and collects for all four entities.11Collin County. Tax Assessor: Property Taxes Bills go out in October, and the full amount is due by January 31. Taxes still unpaid on February 1 are delinquent under state law.12State of Texas. Texas Tax Code 31.02 – Delinquency Date
You can pay online, by mail with a check or money order, or in person at any Collin County tax office. Online card payments carry a convenience fee. If your mortgage lender escrows your taxes, the lender pays on your behalf, and your monthly mortgage payment adjusts at the next escrow review when the rate or appraisal changes.
What Late Payment Costs
Missing January 31 is expensive. On February 1, a 6 percent penalty and 1 percent interest are added to the unpaid balance. The penalty increases by 1 percent each additional month, and interest keeps running at 1 percent per month.13State of Texas. Texas Tax Code 33.01 – Penalties and Interest If the balance is still outstanding on July 1, the penalty jumps to a flat 12 percent.
Taxes still delinquent on July 1 can also pick up an additional collection penalty when the taxing unit has contracted with a collection attorney, covering attorney compensation.14State of Texas. Texas Tax Code 33.07 – Additional Penalty for Collection Costs for Taxes Delinquent June 1 Between penalties, interest, and attorney fees, a bill left unpaid into the summer can grow by 30 percent or more.
Installment and Deferral Options for Seniors and Disabled Homeowners
If you are 65 or older, disabled, or a disabled veteran, you can split the bill into four equal quarterly payments instead of paying it all by January 31. The first installment and a written notice to the tax office are due before the regular delinquency date, and the remaining three are due before April 1, June 1, and August 1.15State of Texas. Texas Tax Code 31.031 – Installment Payments of Certain Homestead Taxes No penalties or interest accrue as long as each payment is on time. A missed installment triggers a 6 percent penalty on the unpaid portion plus the standard monthly interest.
The same group of homeowners can defer property tax collection on a homestead entirely. While deferral is in effect, no foreclosure suit or tax sale can proceed against the home. Interest still accrues, but at 5 percent per year rather than 1 percent per month, and the tax lien remains until the deferred amount is paid.16State of Texas. Texas Tax Code 33.06 – Deferred Collection of Taxes on Residence Homestead of Elderly or Disabled Person The full balance comes due when you no longer own or occupy the home, so deferral helps cash flow now at the cost of a larger bill later.
