How much are property taxes in Johnson, Ellis, and Dallas County for southern DFW buyers?

Property taxes in southern DFW are not a single number. They are a layered stack of rates set by your county, city, school district, and sometimes special districts. Depending on exactly where you buy, two homes at the same price can carry annual tax bills that differ by thousands of dollars. The Texas homestead exemption and the state's 10% appraisal cap can reduce what you actually owe over time, but only if you file correctly and only on a primary residence.

How the Taxing Unit Stack Works in Southern DFW

When I walk buyers through their expected payment in this market, the first thing I explain is that there is no single "DFW tax rate." Every property sits inside multiple taxing jurisdictions at once, and each one sets its own rate independently.

Your bill is the sum of every applicable rate multiplied against your property's taxable value, which is the appraised value minus any exemptions you qualify for. In Texas, that calculation is done by the county appraisal district, not by the taxing units themselves.

The units that most commonly appear on a southern DFW tax bill include:

• County (Dallas, Johnson, or Ellis, depending on your location)


• City or municipality (if you are inside city limits)


• School district (ISD) (the single largest line item for most homeowners)


• Special districts (hospital, community college, flood control, MUD, etc.)

According to the Dallas County Tax Office, total bills can differ sharply by school district and subdivision even within the same county, because every taxing unit in the stack sets its own rate for each tax year.

Dallas County: What the Official Rates Show

Dallas County has published its most recent official rate information through August 2026. For Tax Year 2025, Dallas County adopted a countywide rate of $0.215500 per $100 of assessed value, broken into $0.208765 for Maintenance and Operations and $0.006735 for Interest and Sinking, per the Dallas County adopted tax-rate notice.

For 2026, Dallas County's most recent official notice lists a no-new-revenue rate of $0.203785 per $100 and a voter-approval rate of $0.224650 per $100, per the Dallas County 2026 tax-rate notice. The final adopted rate for Tax Year 2026 will be set by the county commissioners and may fall anywhere in that range.

The county rate alone, however, is only one piece of the bill. The Dallas County Tax Office rate table for Tax Year 2025 shows the following for buyers inside the City of Dallas and Dallas ISD:

The 2025 property tax rates for buyers within the City of Dallas and Dallas ISD include $0.215500 per $100 of assessed value for Dallas County, $0.698800 for the City of Dallas, and $0.993835 for Dallas ISD. Together, these three taxing units account for a combined rate of $1.908135 per $100 of assessed value, before any other applicable taxes or assessments.

That stack alone totals roughly $1.908 per $100 before any special-district rates are added. On a home with a taxable value of $350,000, that combined rate produces a substantial annual bill. This is why buyers shopping in South Dallas, Cedar Hill, Lancaster, or DeSoto need to look at the full rate stack for their specific address, not just the county rate.

The Dallas Central Appraisal District tax-rate page publishes the complete unit-by-unit breakdown for every taxing entity in the county and is the most reliable place to look up the rates that apply to a specific property address.

Johnson and Ellis Counties: What Buyers Should Know

Buyers in Mansfield, Burleson, Midlothian, Venus, and Waxahachie often fall inside Johnson or Ellis County, and the rate structure works the same way. A county rate, an ISD rate, a city rate, and any applicable special-district rates all stack together.

Because the research notes for this post did not capture a verified primary-source rate from Johnson County or Ellis County tax offices in time for publication, I am not going to put numbers on the page that I cannot confirm. What I can tell you is that the methodology is identical to Dallas County, and the ISD rate is typically the largest single line item regardless of which county you are in.

Before you make an offer on a home in Mansfield, Burleson, Midlothian, or anywhere else in Johnson or Ellis County, pull the current rate table from the Texas Comptroller's property tax resources or ask the county appraisal district directly. I do this for every buyer I work with in those areas so there are no surprises when the first escrow analysis comes in.

Texas Homestead Exemptions and the Appraisal Cap

Two tools in Texas law can meaningfully reduce what you owe after you close, but neither one is automatic the moment you sign a deed.

The $140,000 School District Exemption

Texas law requires every school district to provide a $140,000 residence homestead exemption on the appraised value of a qualified primary residence, according to the Texas Comptroller's exemption guide. Because the ISD rate is the largest line item on most bills, this exemption has the biggest dollar impact of any exemption you will file.

On top of the mandatory school-district exemption, local taxing units may adopt optional exemptions of up to 20% of appraised value. Counties that collect farm-to-market or flood-control taxes must also provide a $3,000 residence homestead exemption on those levies. Dallas ISD's 2025 rate table also reflects a $60,000 age-65-or-disabled exemption, per the Dallas Central Appraisal District 2025 tax-rate document.

The 10% Appraisal Cap

Once you have a homestead exemption on file, the Texas Comptroller confirms that your property's appraised value for tax purposes cannot increase by more than 10% per year, regardless of what the market does. This matters most in a rising market because it puts a ceiling on how fast your tax bill can grow. The Comptroller notes that a related circuit-breaker limitation for certain properties expires December 31, 2026, so buyers purchasing this year should confirm the current rules with their county appraisal district or a tax advisor.

Neither the exemption nor the cap applies to a property that is not designated as your primary residence. Investment properties and second homes do not qualify.

How Property Taxes Affect Your Monthly Mortgage Payment

Most lenders in Texas escrow property taxes as part of your monthly payment. That means your lender collects a portion each month, holds it in an escrow account, and pays the tax bill when it comes due. The practical effect is that your monthly payment is not just principal and interest. It includes your estimated annual tax bill divided by 12.

Here is why this matters at the offer stage: the tax bill the seller paid last year may be based on a lower appraised value than the price you are paying. After you close, the appraisal district will reassess the property. If the new appraised value is higher than the prior year's, your escrow payment will increase when your lender does its first annual escrow analysis, usually 12 months in.

I always walk my buyers through this before they finalize their budget. The payment you qualify for at the time of your loan approval is based on current taxes. If those taxes jump after reassessment, your monthly payment goes up, even though your loan balance did not change. Knowing this ahead of time lets you build a realistic cushion into your budget rather than being caught off guard.

For a home in the City of Dallas with the Dallas ISD stack, the difference between a pre-homestead and post-homestead tax bill can be significant once the $140,000 school-district exemption takes effect. Your lender and your title company can help you model both scenarios before you close. If you are looking at active listings in the area, this Dallas home listed at $459,000 is a good example of the price range where the ISD stack has the most visible impact on a monthly payment.

For buyers in the Fort Worth corridor, including properties like this Fort Worth home at $350,000, the rate stack will differ from Dallas County, and pulling the correct ISD and city rates for that specific address is the only way to budget accurately.

Your specific monthly impact depends entirely on your home's appraised value, the exact taxing units that apply to your address, and which exemptions you qualify for. That is not a number I can put on a blog page, because it changes for every property. What I can do is run through it with you before you make an offer so you know exactly what you are buying into.

Frequently Asked Questions

How are property taxes calculated in southern Dallas County?

Your tax bill is calculated by multiplying your property's taxable value (appraised value minus exemptions) by the combined rate of every taxing unit that applies to your address. In southern Dallas County, that typically means the county rate, the city rate, the school district rate, and any applicable special-district rates. The Dallas Central Appraisal District publishes the full rate breakdown by entity so you can look up any specific address.

What homestead exemptions can Dallas County homeowners claim?

Texas law requires school districts to provide a $140,000 residence homestead exemption on your appraised value, per the Texas Comptroller. Additional optional exemptions of up to 20% of appraised value may be available from other local taxing units. Homeowners who are 65 or older or who have a qualifying disability may also be eligible for additional exemptions. You must file an application with the county appraisal district, and the exemption applies to your primary residence only.

How much do Dallas ISD taxes add to a home payment?

Dallas ISD's Tax Year 2025 rate was $0.993835 per $100 of taxable value, per the Dallas County Tax Office. That is typically the single largest line item on a Dallas ISD homeowner's bill. After the $140,000 school-district homestead exemption, the taxable value used for the ISD levy is reduced, which can produce a meaningful reduction in the annual bill and the monthly escrow amount.

When do homestead exemptions start affecting my tax bill after closing?

You must file a homestead exemption application with the county appraisal district after you close, and it generally takes effect for the tax year following your filing. In Texas, you can file any time after January 1 of the year you qualify, and the deadline is typically April 30, though late filing is sometimes permitted. The exemption does not apply retroactively to the year you purchased, so your first full year's bill may be higher than subsequent years once the exemption is in place.

Do property taxes get paid through the mortgage escrow in Texas?

Most Texas lenders require property taxes to be escrowed as part of your monthly mortgage payment. The lender collects a monthly amount, holds it in escrow, and pays the tax bill directly when it comes due. Your escrow payment is recalculated at least once a year, so if your tax bill increases after reassessment, your monthly payment will adjust accordingly. Confirm the escrow requirements with your specific lender before closing.

Which tax rates matter most when buying in South Dallas, Cedar Hill, Lancaster, or DeSoto?

In all of those areas, the school district rate is typically the largest single component of your total bill. The city rate and county rate add to it, and special-district levies (hospital districts, community college districts, etc.) can add more. Because the rates differ by ISD and municipality, two homes at the same price on opposite sides of a city or district boundary can carry materially different annual bills. Always pull the full rate stack for the specific address before budgeting your payment.

The Bottom Line

Property taxes in southern DFW are not a single rate you can look up in one place. They are a layered stack that changes by county, city, school district, and special district, and the difference between locations can be thousands of dollars per year on the same home price. The Texas homestead exemption and the 10% appraisal cap are real tools that reduce your bill over time, but they require a timely filing and apply only to your primary residence.

Before you make an offer anywhere in Johnson, Ellis, or Dallas County, I can pull the current rate stack for that specific address and walk you through a realistic payment estimate, including what changes after your homestead exemption kicks in.
