Dallas County Commissioners voted 3-2 on August 11, 2026 to raise the county property tax rate to $0.248650 per $100 of taxable value — up from $0.215500 in 2025, a 15.4% increase. That is the largest Dallas County rate increase in recent memory, and if you own or are buying a home in Garland, Mesquite, Irving, or anywhere else in Dallas County, it is now flowing into your annual tax bill and your monthly mortgage escrow. I'm Bond Peter Njoku (NMLS #2670329), a mortgage loan officer serving Garland and the greater DFW area, and I want to break down what this actually means in dollars — because your servicer will eventually adjust your escrow to reflect it.
What exactly did Dallas County change in 2026?
The Dallas County rate went from $0.2155 to $0.2487 per $100 of assessed value — a jump of 3.32 cents per $100. The vote was 3-2, meaning this was not unanimous. The increase raises taxes on a $100,000 assessed value by approximately $29.08 per year.
It is important to understand that the county rate is just one component of your total property tax bill. Your bill also includes your city rate, your school district rate, and potentially a community college or special district rate. The county line item — while it rose 15.4% — is typically a smaller percentage of your total bill than your school district.
How much does the Dallas County increase add to monthly mortgage escrow?
| Home Value | Annual County Tax — 2025 Rate | Annual County Tax — 2026 Rate | Annual Increase | Monthly Escrow Increase |
|---|---|---|---|---|
| $250,000 | $539 | $622 | +$83 | +$6.91 |
| $300,000 | $647 | $746 | +$99 | +$8.25 |
| $350,000 | $754 | $870 | +$116 | +$9.67 |
| $400,000 | $862 | $995 | +$133 | +$11.08 |
On its own, $8-$11 more per month may not seem like much. But this sits on top of already-rising Texas homeowners insurance (up 18-28% in 2026 with an average annual premium of $4,560) and the rising mortgage rate environment. The compounding effect on PITI is significant for buyers at the edge of their qualifying budget.
What is the total combined property tax rate in Garland, Mesquite, and Irving?
The county rate is one line. Your real mortgage escrow is based on the combined rate across all taxing entities. Here is what buyers in key Dallas County cities are typically looking at:
| City | County Rate | City Rate (approx) | School District Rate (approx) | Combined Effective Rate | Annual Tax — $350K Home | Monthly Escrow |
|---|---|---|---|---|---|---|
| Garland | 0.2487% | ~0.52% | ~1.17% (GISD) | ~1.94% | $6,790 | $566 |
| Mesquite | 0.2487% | ~0.55% | ~1.22% (MISD) | ~2.02% | $7,070 | $589 |
| Irving | 0.2487% | ~0.51% | ~1.15% (CISD) | ~1.91% | $6,685 | $557 |
| Collin County — McKinney (comparison) | 0.1514% | ~0.52% | ~1.09% (MISD) | ~1.76% | $6,160 | $513 |
| Denton County — Lewisville (comparison) | varies | varies | ~1.07% (LISD) | ~1.80% | $6,300 | $525 |
The difference between a $350,000 home in Garland (combined ~1.94%) and a $350,000 home in McKinney (combined ~1.76%) is about $630 per year in taxes — or $52.50 per month in escrow. On a bigger purchase the gap widens. That said, Garland and Mesquite home prices are typically $80,000-$130,000 lower than Collin County equivalents, which often makes the PITI comparison more favorable to Dallas County for budget-conscious buyers.
How does the tax increase affect mortgage qualifying?
Lenders calculate your front-end debt-to-income ratio using your full PITI. Here is what a typical Garland first-time buyer scenario looks like at the new combined effective rate:
- Purchase price: $285,000
- Loan (3.5% FHA down): $274,988
- P&I at 6.88% (FHA, 30yr): ~$1,805/mo
- Property taxes at 1.94% combined: ~$461/mo
- Homeowners insurance (Texas avg): ~$380/mo
- FHA mortgage insurance premium: ~$229/mo
- Total PITI: ~$2,875/mo
- Income needed at 43% DTI: ~$6,687/mo gross (~$80,250/yr)
With the 2025 county rate, the tax line was about $8-9 lower per month. It is a small difference on its own, but when your combined rate is already ~2.0%, every basis point matters for buyers right at their income ceiling.
Named scenario: Mesquite first-time buyer, fall 2026
I recently worked with a client looking at a $295,000 Mesquite home — a 3/2 brick house built in 1988, well-maintained, great bones. Her credit score was 617, so we went FHA. Her employer-provided gross income was $78,000/year. When we built out her full PITI — $1,876 P&I, $497 in taxes (Mesquite's combined rate on $295K), $380 insurance, and $244 in FHA MIP — her total came to $2,997/month. That put her front-end DTI at 46.1%, just inside the FHA guideline. Had she been looking at the same price point with a higher combined tax rate, she would have been over. The new county rate adds about $9/month to that same scenario going forward. It tips no one over the edge by itself, but stacked with rising insurance, it narrows the margin.
What Dallas County homeowners should do now about their escrow
If you already own a Dallas County home, watch for your annual escrow analysis. Your servicer reviews escrow once per year, and when they update it to reflect the new county rate, your monthly mortgage payment will increase slightly. You will receive a notice 30-45 days before the change takes effect. You can avoid a shortage by calling your servicer proactively and asking for an escrow analysis — or by making a voluntary lump-sum deposit to your escrow account.
If you closed in 2026 and have not yet filed your homestead exemption, do that before April 30, 2027 at the Dallas Central Appraisal District (dallascad.org). A homestead filing saves you $700-$1,200 per year on a typical Dallas County home — $58-$100 off your monthly escrow.
Frequently Asked Questions
How much does Dallas County's 2026 property tax increase add to my monthly mortgage payment?
I'm Bond Peter Njoku (NMLS #2670329) and the Dallas County portion adds roughly $7-$11 more per month in escrow depending on your home value. On a $300,000 Garland home, the county-specific increase is about $8.25 per month. Your total monthly tax escrow — including the city and school district rates — is more significant, typically $456-$600 per month on homes in the $280,000-$350,000 range. I build exact PITI estimates for every buyer I work with so there are no surprises. Call or text me at 469-545-7180.
Does Dallas County's property tax increase affect how much house I can qualify for?
I'm Bond Peter Njoku (NMLS #2670329) and yes, a higher PITI reduces your maximum purchase price slightly. Every $100/mo increase in taxes reduces the qualifying loan amount by roughly $12,000-$14,000 at current rates. The Dallas County increase itself moves the needle by $8-$11/month, which is minor. The bigger factor is Dallas County's combined effective rate of ~1.9-2.2% versus the ~1.7% effective rate in Collin County — that difference runs $800-$1,500 per year on a $350K home. I run cross-county PITI comparisons for buyers every day. Call or text me at 469-545-7180.
When do I need to file my homestead exemption after buying a Dallas County home?
I'm Bond Peter Njoku (NMLS #2670329) and if you purchased a Dallas County home in 2026, your homestead exemption filing window opens January 1, 2027, with a deadline of April 30, 2027. File with the Dallas Central Appraisal District at dallascad.org. A homestead exemption typically saves $700-$1,200 per year in Dallas County — up to $100 per month off your escrow payment. Given the 15.4% county rate increase now in effect, this exemption offsets much of the increase for eligible homeowners. Call or text me at 469-545-7180 if you have questions.
How does Dallas County compare to Collin and Denton County for property taxes?
I'm Bond Peter Njoku (NMLS #2670329) and Dallas County's combined effective rates — typically 1.9-2.2% all-in — run higher than Collin County's 1.7-1.76% and are comparable to Denton County cities like Lewisville or Denton. On a $350,000 home, paying 2.0% combined versus 1.75% means roughly $875 more per year in taxes, or $73 more per month in escrow. However, Dallas County cities like Garland and Mesquite typically have home prices $80,000-$130,000 lower than comparable Collin County cities, so the lower purchase price often more than offsets the higher rate. Call or text me at 469-545-7180 and I will run the full PITI comparison for you.
