Few things about homeownership in North Texas feel simple, from deciphering your property tax bill to understanding how exemptions work. Property taxes appear every year like clockwork, so knowing how Dallas County operates will save you money and stress.
How Are Property Taxes In Dallas County Calculated?
It’s simple math with moving parts that change annually. Your tax bill is a product of your property’s taxable value times the tax rates for each local taxing unit that services your home.
Every year on January 1, your home’s value is set for the tax year. This is known as the valuation date. Your taxable value is the determined market value minus any exemptions you qualify for.
Who Sets Dallas County Property Tax Rates?
While the appraisal district determines your home’s value, they don’t set tax rates. The taxing units’ local governing bodies adopt the rates used to calculate Dallas property taxes every September. Districts like the Dallas City Council, Dallas County Commissioners Court, and Dallas school board trustees set rates needed to provide services like schools, roads, and public safety.
Who Is The Dallas Central Appraisal District (DAC)?
Also known as DCAD, the Dallas Central Appraisal District is the primary appraisal agency for Dallas County. DCAD appraises all real, personal, and business property within Dallas County for ad valorem taxes. As a political subdivision of the State of Texas, they cannot levy taxes or determine your tax rate.
The district appraises properties according to state law, with the goal that all property values are “equal and uniform.”
When Are Dallas County Property Taxes Due?
Property tax bills are mailed out by the Dallas County Tax Office beginning on October 1. Technically, your bill is due when you receive it. January 31 is the deadline that matters because you’ll pay a penalty if you miss it. To avoid late fees, you must pay Dallas County property taxes on or before January 31 of the following year.
- October 1 — Tax bills are mailed to homeowners.
- January 31 — Last day to pay your property taxes without penalty.
- February 1 — Dallas County property taxes are delinquent.
Is there A Cap On How Much My Appraised Value Can Increase?
Yes, there is a cap on the appraised value. With a General Residence Homestead Exemption on your primary residence, your appraised value can only increase by a maximum of 10% each year, known as a “Homestead Cap.”
It applies in the second year after you receive your homestead exemption and each year thereafter. Just keep in mind this cap only affects your appraised value, not your market value. So, if values jump by 20% across Dallas County, your taxes are still capped at that 10% increase.
There is also the “Circuit Breaker” cap, which is for non-homestead properties such as commercial properties. This annual appraised value can increase at 20% per year.
What Is A Notice Of Appraised Value, and When Will I Get It?
Your Notice of Appraised Value comes from DCAD and shows you what they think your home is worth for the current year. Your NOI is not a tax bill, but it will determine what your bill looks like. DCAD will begin mailing NOIs for real property during the week of April 15. In 2026, the first batch of notices was mailed on April 15, 2026.
What Is A Tax Ceiling, and Who Qualifies?
A tax ceiling is sometimes referred to as a “tax freeze.” Once you qualify for and receive a tax ceiling, the school taxes assessed against your home can never increase as long as you continue to own and live in that home.
Tax ceilings are available to:
- Homeowners 65 or older.
- Disabled persons.
- Surviving spouses (younger than 55) of a person who was receiving a ceiling when they died. The spouse must be age 55 or older when they apply.
Are There Property Tax Exemptions For Seniors In Dallas?
Yes! Dallas County has exemptions available specifically for seniors, in addition to the tax ceiling mentioned above. If you are age 65 or older, you can remove additional dollars from your home’s value for school taxes. Many taxing units within Dallas County offer local-option exemptions for senior homeowners. These can reduce your home’s value for Dallas County property taxes and are provided by the city of Dallas and Dallas County.
Can I Protest My Dallas Property Taxes?
Yes. You have the right to protest the value of your home as determined by DCAD. If you believe your home is worth less than what DCAD has valued it at, or that it isn’t being valued equally to other homes in your neighborhood, you can file a protest.
Quick Tip: Visit DCAD’s website and look at the “Current Value” breakdown before filing a protest. You’ll see how DCAD arrived at their assessed value.
How Do I Know If I Need To Start The Protest Process?
Still not sure if you should file a protest? If you answer yes to any of the questions, it is a sign that you may want to file a protest.
- Is the market value shown on your NOI more than you would sell your home for today?
- Are similar homes around you valued lower than your home?
- Is DCAD missing information on your home (i.e. square footage)?
If you answered YES to any of these questions, find a Dallas property consultant to help you file a protest.
When Is The Deadline To File A Property Tax Protest In Dallas?
The deadline for most residential property tax protests is May 15. To be precise, you have until May 15 or 30 days after the appraisal district mailed your notice, whichever is later, to file your protest. For most Dallas homeowners, May 15, 2026, is the deadline because many Dallas residents received their NOI’s on April 15, 2026.
What If I Miss The May 15 Deadline To Protest My Property Taxes?
You lose your right to protest that year’s value. There are some exceptional circumstances that allow you to file a late protest (i.e., you did not receive a notice of appraisal), but they are extremely difficult to win.
Do I Need To Hire A Property Tax Consultant, and Where To Find A Property Tax Consultant?
You don’t have to hire a consultant to file a protest. But they can be a huge benefit to you as you navigate through the process with DCAD and the ARB. Property tax consultants know the laws and the Dallas real estate market like the back of their hand and understand what evidence the ARB wants to see to win your case.
