Newer developments may also carry MUD or PID assessments on top of these rates.
Rockwall ISD: The Largest Share
Rockwall ISD accounts for roughly 68% of a typical City of Rockwall homeowner's property tax bill -- a larger share than in most Texas counties because the city and county rates are both unusually low. The tax year 2025 rate of $1.0669 per $100 is a decrease of $0.1331 from the prior year's rate of $1.20.
This decrease came through a combination of two moves: voters approved a VATRE (Voter-Approval Tax Rate Election) in November 2025 that increased the M&O rate by 12 cents, but the district simultaneously reduced the I&S (debt service) rate by 8 cents through bond refinancing. The net result is a rate decrease of roughly 13 cents. Even with the VATRE, Rockwall ISD's rate remains among the three lowest of 18 surrounding districts.
Rockwall ISD's rate has decreased more than 44 cents since the 2016-17 school year, a sustained reduction driven by growth in the district's taxable property values.
Royse City ISD
Royse City ISD serves portions of Rockwall County with a total rate of $1.1805 per $100, a decrease of $0.077 from the prior year. On a $350,000 home, a Royse City ISD homeowner pays roughly $397 more per year in school taxes compared to a Rockwall ISD homeowner at the same value.
City Rate Variation
Rockwall County has wide variation in city tax rates:
| City | 2025 Rate per $100 | Change from 2024 |

| Fate | $0.2592 | -1.9% |
| Heath | $0.2903 | +5.6% |
| Royse City | $0.5780 | -1.0% |
Royse City's rate is more than double the City of Rockwall's rate. On a $350,000 home, a Royse City homeowner pays roughly $1,157 more in city taxes than a Rockwall homeowner would on the same value.

How Your Rockwall County Property Tax Bill Is Calculated
Your total bill is your taxable value -- appraised value minus exemptions -- multiplied by each entity's rate. Here's how that breaks down for a City of Rockwall homeowner with a $450,000 home and the $140,000 homestead exemption:
| Component | Amount |
|---|---|
| Appraised value | $450,000 |
| Less: School homestead exemption (SB 4 / Prop 13) | -$140,000 |
| Taxable value (school) | $310,000 |
| Rockwall ISD tax ($310,000 x 1.0669%) | $3,307 |
| Rockwall County ($450,000 x 0.2547%) | $1,146 |
| City of Rockwall ($450,000 x 0.2474%) | $1,113 |
| Total estimated bill | $5,566 |
Worth noting: The $140,000 school homestead exemption takes effect in 2026 under SB 4 (Proposition 13) and only reduces the ISD portion. The City of Rockwall and Rockwall County each offer their own exemptions for additional savings. Your final bill depends on your specific city, ISD, and exemptions on file.

Why Your Rockwall County Property Tax Bill May Be Higher Than Expected
Even if tax rates decrease, your bill can increase for several reasons:
Rising Appraisals
The Rockwall Central Appraisal District revalues all properties annually. Rockwall city median sale prices were up 14.5% year-over-year in September 2025, meaning appraised values are likely rising. Even with Rockwall ISD's 13-cent rate decrease, higher appraised values can push your bill upward.
High Home Values
Rockwall County has some of the highest median home values in the DFW metro. The average RISD taxable home value is $540,000 ($400,000 after homestead exemption). Higher values mean higher absolute tax bills even at lower rates. The average VATRE impact is approximately $160 per year ($13 per month) for the typical homeowner.
Royse City Premium
Homeowners in Royse City face a significantly higher total rate than those in the City of Rockwall. On a $350,000 home in Royse City with Royse City ISD, the total annual tax bill is approximately $7,046 -- nearly the same dollar amount as a $450,000 home in the City of Rockwall despite the lower home value.
How to Lower Your Rockwall County Property Taxes
Rockwall County's low rate doesn't mean low bills -- with a $450,000 median home value, the dollar amounts are substantial. Here's how to keep yours in check.
1. File for Homestead Exemption
Apply for your homestead exemption if you haven't already. Beginning in 2026, the school district exemption rises to $140,000 under SB 4 (Proposition 13), saving a typical Rockwall ISD homeowner roughly $1,494 per year in school taxes alone. The City of Rockwall and Rockwall County offer additional exemptions.
The filing deadline is April 30, and you can file up to two years late to claim retroactive savings.
2. Protest Your Appraised Value
With Rockwall city median sale prices up 14.5% year-over-year, the appraisal district is likely pushing values higher. Protesting your Rockwall County property tax appraisal gives you the chance to present comparable sales or condition evidence showing your home is overvalued. Review your Notice of Appraised Value when it arrives in April or May and file before the deadline. Check Rockwall County protest deadlines to make sure you don't miss your window.
