Dallas County Property Taxes: Assessed & How to Protest
How Are Dallas County Property Taxes Assessed and How Do You Protest Them?
The Dallas Central Appraisal District (DCAD) sets your home’s taxable value as of January 1 each year and mails a Notice of Appraised Value in April if your value changes. You have until May 15, or 30 days after DCAD mails your notice, whichever is later, to file a protest — online through DCAD’s uFile system, by mail, or in person. Most protests are resolved through an informal review with an appraiser before ever reaching a formal Appraisal Review Board (ARB) hearing.

Every homeowner in Dallas County gets a letter from DCAD at some point that either confirms their value stayed flat or tells them it went up — sometimes by a lot. If you’ve never protested before, the process feels bureaucratic and vague. It isn’t. It’s a specific window, a specific form of evidence, and a deadline that doesn’t move for anyone.
Here’s exactly how Dallas County assesses your property, what you’ll actually pay, and how to push back on a number that doesn’t match reality.
How DCAD Assesses Your Home’s Value
DCAD is the agency responsible for appraising every parcel of real estate in Dallas County — not the city, not the school district, not the county tax office. Those entities set tax rates. DCAD sets the value the rates get applied to.
A few things to know about the timeline:
• The valuation date is always January 1. Whatever your home is worth on that date is what gets taxed for the entire year, even if you sell, renovate, or the market shifts three months later.
• Notices go out in April. DCAD is required to mail a Notice of Appraised Value when your assessed value increases, when you gain or lose an exemption, or when ownership changes. If your value didn’t change, you may not receive a notice at all — check your account on the DCAD website directly if you’re unsure.
• Appraisals are mass-produced, not individual. DCAD uses computer-assisted mass appraisal models built on neighborhood sales data, square footage, age, and condition codes. That’s efficient at scale, but it means your specific home’s condition — a bad foundation, an outdated kitchen, deferred maintenance — often doesn’t get factored in unless you tell them.
If you have a homestead exemption on file, your assessed value (the number taxes are calculated on) can’t increase more than 10% per year, regardless of what the market does. This cap doesn’t limit market value — it limits how fast your taxable value can climb. It only applies once you’ve owned and homesteaded the property as of January 1 of the prior year, so it won’t help you in your first year of ownership.
What Dallas County Homeowners Actually Pay
Dallas County’s own tax rate is a small piece of your total bill. For the current tax year, Dallas County’s adopted rate is $0.2155 per $100 of taxable value — combining maintenance and operations with debt service.
The bigger factor is your school district. For a home inside Dallas city limits in the Dallas ISD boundary, the combined rate across county, city, and school district runs close to 2.2% of taxable value — and Dallas ISD alone typically makes up close to half of that total bill. Rates shift meaningfully depending on which city and school district your property sits in, since every jurisdiction sets its own rate independently.
That’s true across the Metroplex, not just in Dallas proper. If you’re comparing where to buy based on tax burden, we broke down how rates compare across Mansfield, Arlington, and Fort Worth — the same logic applies when you’re weighing Dallas County cities against each other.
A few exemptions that directly reduce what you owe:
• General homestead exemption — reduces your home’s value for school tax purposes and currently sits at $140,000 following the statewide homestead increase approved by voters. File Form 50-114 with DCAD by April 30 for the exemption to apply for that tax year.
• Over-65 or disability exemption — adds an additional $60,000 off the school tax value on top of the general homestead exemption, for a combined total reduction on that portion of your bill. You can only claim one of the two (over-65 or disability), not both, and most owners take whichever produces the larger benefit.
• Local option exemptions — some cities and the county itself offer additional percentage-based exemptions on top of the state-mandated ones. Confirm what applies to your specific address through DCAD’s online account lookup.
None of these exemptions lower your appraised market value. They lower the taxable value your rate gets applied to — which is a different fight than protesting your appraisal.
How to Protest Your DCAD Appraisal
If your notice shows a number that’s higher than what your home would realistically sell for, you have the right to protest it. Here’s the process, start to finish.
The Deadline
You must file your protest by May 15, or 30 days after DCAD mails your notice, whichever is later. There’s no grace period and no appeal for missing it — if the deadline passes, that value stands for the year. Business personal property protests run on a separate, later deadline, but for a residential homeowner, May 15 is the number to circle.
How to File
You have three options:
1. Online (uFile) — the fastest route, and the one DCAD encourages for both informal review and evidence submission.
2. By mail — must be postmarked by the deadline, not received by it.
3. In person — delivered to DCAD’s office before it closes on the deadline date.
Informal Review First
Once you’ve filed, DCAD typically offers an informal review with an appraiser before your case ever reaches a hearing. You submit your evidence — through uFile is preferred for residential accounts — and the appraiser reviews it and may extend a settlement offer directly. A large share of protests resolve at this stage, without ever sitting in front of a panel.
The Formal ARB Hearing
If you don’t reach an agreement informally, your protest moves to a three-member Appraisal Review Board panel. Hearings run from mid-April through mid-July. It’s structured like a hearing — you present evidence, DCAD presents its evidence, and the panel rules on the record in front of them. It’s more formal than the informal review, but nowhere near as intimidating as a courtroom. Most residential hearings run 15 to 20 minutes.
What Evidence Actually Moves the Needle
Vague frustration (“my taxes are too high”) doesn’t work. Specific, documented evidence does:
• Comparable sales — properties similar to yours in size, age, and condition that sold for less than DCAD’s value. Texas is a non-disclosure state, so exact sold prices aren’t published publicly the way they are in some other states. This is one of the most common reasons homeowners bring their agent into the protest conversation — we can pull confirmed comparable sales data that isn’t accessible through public search.
• Photos of condition issues — foundation cracks, roof damage, outdated systems, anything that would reasonably lower a buyer’s offer.
• Repair estimates — a contractor’s written estimate for a needed repair carries real weight with an ARB panel.
• A recent independent appraisal — if you refinanced or purchased recently and have a licensed appraisal on file, it’s strong evidence.
• DCAD’s own property record — sometimes the district has your square footage, bedroom count, or condition rating wrong. Correcting a factual error can lower your value without any argument about market comparables at all.
Submit your evidence at least five days ahead of a scheduled hearing so the appraiser has time to review it before you sit down.
Whether you protest yourself or bring in help, the goal is the same: make sure DCAD’s number reflects what your home would actually sell for today, not a mass-appraisal estimate that never accounted for your specific property.
Frequently Asked Questions
When will I get my Dallas County appraisal notice?
DCAD mails Notices of Appraised Value in April to any property owner whose value increased, whose exemptions changed, or whose ownership changed during the year. If your value stayed flat, you may not receive a notice — check your account directly on DCAD’s website to be sure.
What’s the deadline to protest my Dallas County property taxes?
You must file by May 15, or within 30 days of the date DCAD mailed your notice, whichever is later. Online filings must go through before midnight on the deadline date, and mailed protests must be postmarked by then.
Do I need a lawyer to protest my property taxes in Dallas County?
No. Most residential protests are handled by the homeowner directly, either informally with a DCAD appraiser or in a short hearing before the Appraisal Review Board. You can also work with a property tax consultant or your real estate agent to help pull comparable data.
Will protesting my appraisal lower my tax rate?
No. Protesting challenges your appraised value, not the tax rate. Your rate is set separately by the county, city, and school district. Lowering your appraised value still lowers your total bill, since the rate gets applied to a smaller number.
Does the 10% homestead cap mean my taxes can’t go up more than 10% a year?
The 10% cap limits how much your assessed value can climb annually if you have a homestead exemption on file — it doesn’t cap your tax bill directly, since rates can still change year to year. It also only kicks in after you’ve owned and homesteaded the property as of January 1 of the prior year.
