Property taxes change what you can afford on a Dallas home because they are part of your monthly payment, so you should price a house on principal, interest, taxes and insurance together. Damon Williamson of The Agency Dallas shows how property taxes affect what you can afford on a Dallas home with a simple calculation you can repeat for any listing.
Dallas County's adopted tax rate for tax year 2026 is $0.248650 per $100 of assessed value (Dallas County, notice of final vote, accessed November 2, 2026). On a $1,000,000 assessed value, the county portion alone works out to $2,486.50 a year, which is arithmetic, not a forecast. Cities, school districts and special districts add their own rates on top, so your total bill is higher.
How do property taxes affect what I can afford in Dallas?
Lenders include taxes in your monthly housing cost, so a higher tax bill lowers the loan you can carry at the same income. Two homes at the same price can have different payments because taxing units differ by address. The practical test is to build the payment, not guess it:
- Start with the assessed value or expected purchase price.
- Look up every taxing unit that applies to the address.
- Add each rate per $100 and multiply by the value divided by 100.
- Subtract any exemptions you qualify for, such as the homestead exemption.
- Divide by 12 and add it to principal, interest and insurance.
Which taxes make up a Dallas property tax bill?
Several separate governments can each levy a rate:
- The county. Dallas County's 2026 adopted rate is $0.248650 per $100.
- The city. The city or town where the home sits.
- The school district. Often the largest share of the bill.
- Special districts. These can include hospital, college or municipal utility districts.
The Dallas County tax office and the appraisal district publish the rates and your account detail. For a walkthrough of your bill, read what to check on your Dallas County property tax bill.
Does the homestead exemption lower my bill?
Yes, if the home is your primary residence and you apply. Texas also limits annual increases in the taxable value of a homestead. Timing matters for new buyers, which is why we wrote about when you can claim the homestead exemption after a year-end purchase.
How do Dallas property taxes compare with other places?
Texas has no state income tax, so local property taxes carry more of the load. Relocating buyers should compare total cost, not one line item. See how Texas property taxes compare with state income tax and how Dallas property taxes compare to California. Luxury buyers weighing suburbs can also read property taxes in Southlake and Westlake.
Can I protest my assessed value?
Yes. Owners can protest an appraisal, and a sound protest uses comparable sales and condition evidence. Buyers should check the current assessed value, but remember that a purchase can lead the appraisal district to reassess the property at a higher figure. Ask your agent to model the bill at the purchase price, not the seller's current assessment.
What should I do before making an offer?
Run the monthly payment with the taxes at the purchase price, not the seller's bill. Damon Williamson of The Agency Dallas builds that estimate for buyers as part of offer strategy.

Frequently asked questions
How much are property taxes on a home in Dallas?
It depends on every taxing unit at the address. Dallas County's 2026 rate is $0.248650 per $100, and the city, school district and special districts add more. Add the rates, multiply by value divided by 100, and subtract exemptions.
Do property taxes get included in my mortgage payment?
Usually, yes. Most lenders collect taxes and insurance monthly in escrow, so your payment includes them. A higher tax bill raises the escrow amount and can lower the loan you qualify for at the same income.
Will my taxes go up after I buy a Dallas home?
They can. The appraisal district may update the assessed value to reflect the sale. Ask your agent to estimate taxes at your purchase price and check whether the homestead exemption and appraisal limits apply to you.
Is the homestead exemption automatic?
No. You generally have to apply for it with the appraisal district for your primary residence. Apply after you close and keep the confirmation, since the exemption can reduce your taxable value and your annual bill.
How do I estimate taxes before making an offer?
Use the purchase price, find every taxing unit for the address, and add their rates. Damon Williamson of The Agency Dallas prepares this estimate for buyers so the monthly payment is realistic before an offer goes in.
