How Property Tax Differs Between Collin, Dallas, Smith, and Gregg Counties

In Texas, property taxes are a major ongoing cost of homeownership. They fund essential services like schools and public safety. However, the rates and total tax burden can vary widely depending on the county.

According to Bethany Ashby, a local loan expert, “Property taxes can have just as much impact on your monthly payment as interest rates or insurance. That’s why it’s so important to understand how they differ county by county.”

Let’s break down how property taxes compare across Collin, Dallas, Smith, and Gregg Counties and what it means for your homebuying budget.

Collin County

Collin County, located north of Dallas, has one of the highest effective property tax rates in Texas. Based on data from Tax-Rates.org, the median annual tax is approximately $4,351 on a median home value of $198,100. This equals about 2.19% of assessed value. According to PropertyTax101.org, the high cost results from both higher home values and the combined tax rates from school districts, cities, and special taxing units.

Dallas County

Dallas County's median tax bill is around $2,827 for a median-valued home of $129,700, which equates to a 2.18% tax rate, per Tax-Rates.org. While the raw amount is lower than Collin’s, Dallas County still places a heavy burden on homeowners due to overlapping taxing districts. Homebuyers should expect a similar percentage of home value to go toward taxes.

Smith County

If you're considering a move to East Texas, Smith County may offer some tax relief. The median property tax here is about $1,607 on a $118,000 home, with an effective tax rate of just 1.36%, according to Tax-Rates.org. This lower burden can make a significant difference in long-term affordability, especially for first-time buyers or retirees looking to stretch their budget.

Gregg County

Gregg County also offers relatively affordable property taxes. The 2025 voter-approval tax rate was reported as $0.304331 per $100 of assessed value, or roughly 0.30%, per Gregg County’s official notice. Actual bills vary based on local city and school district rates, but most homeowners in Gregg will find their annual tax burden well below that of nearby urban counties.

Why These Differences Matter

Higher home values lead to higher tax bills even when the rate is similar.
Local taxing entities, such as school districts or special utility districts, can increase the overall rate.
East Texas counties like Smith and Gregg offer a lower overall tax burden, which can increase your buying power.
Exemptions such as the homestead exemption or senior freeze also vary, so it’s important to check with the county appraisal district.

What This Means for Your Budget

As Bethany explains on easttexaslending.com/home, factoring in property taxes is essential when estimating your total monthly payment. “A $250,000 home in Collin County may cost significantly more per month than the same-priced home in Smith County, just because of taxes,” she says.

If you're choosing between locations, don’t just compare home prices. Compare the full cost of ownership. Your mortgage payment, taxes, insurance, and utility rates all play a role.

Final Thoughts

Property taxes are a long-term cost that should be factored into your homebuying decision from the start. Collin and Dallas Counties tend to carry a heavier tax burden, while Smith and Gregg Counties offer more affordable options in East Texas. Understanding these differences can help you choose a location that aligns with your financial goals.
