Every property in Dallas County sits inside a stack of overlapping tax districts, and the Dallas Central Appraisal District currently serves 61 separate local governing bodies that can assess property taxes on a single parcel. Your bill is not one charge from one agency. It is a column of individual levies from the county, your city, your school district, and several special purpose entities, each setting its own rate and each appearing as a separate line. Knowing which Dallas County tax districts cover your property, and at what rate, is the first step toward catching errors, claiming exemptions, and understanding where the money goes.
How the Stacked District System Works
Texas law defines a “taxing unit” as any political subdivision authorized to impose ad valorem property taxes. Counties, cities, school districts, hospital districts, and community college districts all qualify. Each sets its own annual rate independently. Rates are expressed per $100 of taxable value, and the sum of every applicable rate determines your total bill.
Every taxing unit follows a process called truth-in-taxation to adopt that rate each year. The chief appraiser certifies the appraisal roll to each taxing unit by July 25, and the unit’s assessor submits total appraised and taxable values to the governing body by August 1 or as soon as practicable afterward.1State of Texas.

The Districts Most Dallas County Properties Pay
Dallas County
The county itself funds road maintenance, judicial administration, and the sheriff’s office. For 2025, the county’s total tax rate was $0.2155 per $100 of taxable value, split between a maintenance-and-operations component and a smaller interest-and-sinking component used for debt service.5Dallas County. 2025 Tax Rates On a home with a taxable value of $300,000, the county portion alone comes to about $646.
Your City
If you live inside an incorporated city, you also pay municipal taxes. The City of Dallas carries the largest city rate in the county at $0.6988 per $100 of taxable value for 2025, covering fire and police, parks, streets, and general city operations.5Dallas County. 2025 Tax Rates Smaller cities like Mesquite, Garland, and Irving set their own rates. City boundaries and county boundaries are not the same, so your city rate depends entirely on which municipality the parcel falls within.
Your School District
School district taxes typically make up the largest share of a Dallas County tax bill. Dallas ISD’s 2025 combined rate was $0.9938 per $100 of taxable value, and other districts within the county, including Richardson ISD and Highland Park ISD, set their own rates.5Dallas County. 2025 Tax Rates School district boundaries do not follow city lines, so a home in one city can easily fall within a district named after a neighboring community.
Every school district rate has two pieces: a maintenance-and-operations rate funding salaries and day-to-day costs, and an interest-and-sinking rate paying off bonds for facilities.6Texas Education Agency. School District Property Values and Tax Rates State law caps the M&O rate through tax rate compression, which lowers the maximum M&O rate as local property values rise. For tax year 2025, the statewide maximum compressed M&O rate was $0.6322 per $100, and individual districts could fall as low as $0.5689 depending on local value growth.7Texas Education Agency. Tax Year 2025 Maximum Compressed Tax Rates
Parkland Hospital District and Dallas College
Most Dallas County properties are also taxed by at least two special purpose districts. The Parkland Hospital District (Dallas County Hospital District) funds the public hospital system and indigent health care, with a 2025 rate of $0.2120 per $100. Dallas College, the community college district, levied $0.1066 per $100 for the same year.5Dallas County. 2025 Tax Rates Both appear as standalone line items on your statement.
Narrower Special Purpose Districts
Some properties also fall within levee improvement districts, water control and improvement districts, or municipal management districts. These entities fund specific infrastructure such as flood control, water and sewer service, or neighborhood improvements within a defined geographic area. A municipal management district, for example, may finance public improvements and services but cannot carry out law enforcement without city consent. Each district’s powers are limited to whatever its creating legislation authorizes. The line items tend to be small individually, but they add up, and they are easy to miss when scanning a tax statement.
Finding Which Districts Tax Your Property
The Dallas Central Appraisal District maintains a searchable online database where you can look up any property by street address, owner name, business name, or account number.8Dallas Central Appraisal District. Find Property By Street Address DCAD account numbers are 17 characters and use a mix of letters and numbers.9Dallas Central Appraisal District. Find Property By Account Number Pull up the property record and the detail page lists every taxing unit that levies on your parcel, along with each unit’s current rate and any exemptions applied.
Check this every year, not just when you buy. Errors in jurisdictional assignment do happen, and discovering that your property has been placed in a district it doesn’t belong to is something you can address. The detail page also shows whether your homestead, over-65, or other exemption has actually been applied to each individual taxing unit.
Notice of Appraised Value
If your property’s appraised value increased from the prior year, the chief appraiser must mail you a written notice by April 1 for residence homesteads or by May 1 for all other property.10State of Texas. Texas Tax Code TAX 25.19 – Notice of Appraised Value That notice contains the numbers used to calculate your taxes for every overlapping district, and it starts the clock on your right to protest.
Exemptions That Reduce What You Owe
Exemptions directly reduce your taxable value. In a county where five or more taxing entities stack their rates, even a modest exemption saves real money across the whole bill.
Homestead Exemption
The school district homestead exemption under current statute is $100,000 off your appraised value for school district taxes.11State of Texas. Texas Tax Code TAX 11.13 – Residence Homestead Texas legislators passed SB 4 and SJR 2 in 2025 to raise this to $140,000; if voters approved the constitutional amendment, that higher figure applies for the 2026 tax year. Confirm which amount appears on your DCAD record. Declaring a homestead also caps the annual increase in your property’s appraised value at 10 percent, which matters in a county where values have climbed sharply. Cities and the county may offer their own optional homestead exemptions on top of the school district amount. The application deadline for the current tax year is April 30.
Over-65 and Disabled Person Exemptions
Homeowners who are 65 or older, or who meet the legal definition of disabled, qualify for an additional school district exemption beyond the standard homestead amount. The statutory additional exemption is $10,000.11State of Texas. Texas Tax Code TAX 11.13 – Residence Homestead The 2025 legislation proposed raising this to $60,000; verify the current figure on your record. You cannot stack the over-65 exemption with the disabled person exemption. If you qualify for both, choose one. Either exemption also triggers a tax ceiling for school district taxes, freezing the school portion of your bill at the amount owed the year the exemption first takes effect. The over-65 exemption can be filed retroactively for one prior year.
Disabled Veteran Exemptions
Veterans with a service-connected disability receive a partial exemption based on VA disability rating:
- 10 to 29 percent: up to $5,000 off assessed value
- 30 to 49 percent: up to $7,500
- 50 to 69 percent: up to $10,000
- 70 percent or higher: up to $12,000
These amounts apply to one designated property and are set by statute.12State of Texas. Texas Tax Code TAX 11.22 – Disabled Veterans Veterans rated at 100 percent disabled, or classified as individually unemployable by the VA, qualify for a complete exemption on the total appraised value of their residence homestead, effectively eliminating property taxes on that home from every taxing district.
Payment Deadlines and Penalties
Property tax bills go out on or around October 1 each year, and payment is due by January 31. Miss that date and the account is legally delinquent starting February 1.13Dallas County. Tax Office – Deadlines and Delinquency The penalty and interest schedule escalates fast:
- February: 6 percent penalty plus 1 percent interest (7 percent total)
- March: 7 percent penalty plus 2 percent interest (9 percent total)
- April: 8 percent penalty plus 3 percent interest (11 percent total)
- May: 9 percent penalty plus 4 percent interest (13 percent total)
- June: 10 percent penalty plus 5 percent interest (15 percent total)
- July 1: penalty jumps to a flat 12 percent plus 6 percent interest (18 percent total)
Interest accrues separately at 1 percent per month and never stops as long as the balance remains outstanding.14State of Texas. Texas Tax Code 33.01 – Penalties and Interest July 1 is also when most taxing units refer delinquent accounts to collection attorneys, triggering an additional collection penalty that can reach 15 to 20 percent of the entire outstanding balance, including penalties and interest already accrued.15State of Texas. Texas Tax Code TAX 33.07 A tax bill that was $5,000 in January can become $6,500 or more by midsummer.
If you cannot pay in full by January 31, homestead owners can request an installment payment agreement. Entering an agreement before the account goes to collections prevents the attorney fee from being added. Interest of 1 percent per month still accrues, but no additional penalty is assessed on active agreements for homestead properties.
Protesting Your Appraised Value
The single most effective way to lower what you owe across every overlapping district at once is to challenge the appraised value DCAD assigned. A successful protest reduces the base number that all taxing units multiply by their rates, so even a modest reduction compounds across five or six line items.
The filing deadline is May 15 or the 30th day after your notice of appraised value was delivered, whichever is later.16State of Texas. Texas Tax Code TAX 41.44 – Notice of Protest DCAD offers an online filing tool called uFILE that lets you submit your protest and supporting evidence without visiting the office.17Dallas Central Appraisal District. Dallas Central Appraisal District After filing, you will typically go through an informal review where an appraiser looks at your evidence and may offer a settlement. If you cannot reach agreement, the case moves to a formal hearing before the Appraisal Review Board, generally running from June through August.
The strongest protest evidence is usually comparable sales data: recent sale prices of similar nearby properties that sold for less than your appraised value. Bring photos documenting any condition issues the appraiser may not know about. At the formal hearing, both you and a DCAD representative present evidence to a panel of ARB members, and the board issues a written order several weeks later. If you still disagree after the ARB ruling, you can appeal to district court or pursue binding arbitration for properties appraised at $5 million or less.
