Rockwall Central Appraisal District posted 2026 property tax statements online and scheduled them to mail the week of October 12. The City of Royse City's own figures show the median taxable homestead value fell from $330,358 in tax year 2025 to $316,809 in tax year 2026, a drop of about 4 percent. Even so, the city's estimated tax on that median home goes up, from about $1,909 to about $1,926.
In Royse City, most of the tax base growth now comes from newly built homes, not from existing homes rising in value. When existing values level off, taxing units raise rates to keep revenue growing. A buyer comparing Royse City with Fate, Rockwall or Heath should plan for prices that can be negotiated and a tax bill that can't.
The Tax Figure on a Listing Belongs to the Seller
The friction shows up first at the offer stage. A buyer sees a tax amount on a listing or a seller's statement and plugs it into a monthly payment estimate. That figure reflects the seller's exemptions and the seller's appraisal history. The Comptroller ties those exemptions and the appraisal cap to the owner who qualifies for them.
Here is what the Texas Comptroller and its exemptions page say about how homestead treatment works when a home changes hands:
- The 10 percent limit on yearly increases in a homestead's appraised value applies only to an owner who qualified for the homestead exemption in both the preceding and current year.
- That limit takes effect January 1 of the tax year after the owner qualifies, and it ends January 1 of the year after the owner stops qualifying.
- School districts must exempt $140,000 of a qualifying residence homestead's value from school taxes.
- A buyer who acquires a home after January 1 may receive the general homestead exemption for the applicable part of that year, but only if the previous owner did not receive the same exemption for that year.
If a seller has owned the home for years under the 10 percent cap, their appraised value may sit well below market. If you're buying a home the builder never homesteaded, your first-year exemption depends on the timing rules above. Either way, the number to plan around is the home's value under your ownership, multiplied by 2026 rates. This is general information and not tax or legal advice, so confirm how these rules apply to a specific property with the appraisal district, a tax professional or your lender.
Those 2026 rates are where Royse City's tax base explains itself.
Where Royse City's Tax Base Actually Grew
Every Texas city files a tax rate worksheet on the Comptroller's Form 50-856. Royse City's 2026 worksheet, posted through Collin County's tax assessor, compares property taxed in both years with value that is new this year.
| Line on the city's 2026 worksheet | Value |
|---|---|
| Prior-year value of property taxed in both years, after adjustments | $2,448,964,693 |
| Same property, current-year adjusted value | $2,478,159,072 |
| New improvements added to the roll in 2026 | $169,891,986 |
| Value in newly annexed territory | $472,926 |
| Prior-year value captured in a tax increment financing zone | $244,966,290 |
Property the city taxed in both years gained about 1 percent in value. Construction added almost $170 million in one year, nearly six times that gain. Royse City's tax base is growing, but almost all of the growth comes from new houses and buildings, not from existing ones going up in value.
That pattern drives the rate math. The no-new-revenue rate is the rate that would bring in the same taxes from the same properties as last year. The Comptroller's form notes that it should fall when appraisal values rise. Because existing values barely moved, Royse City's 2026 no-new-revenue rate came out to $0.572105 per $100. That's only slightly below the 2025 adopted rate of $0.578000. When existing homes aren't appreciating, rate decisions do most of the work of increasing revenue.
How Each Taxing Unit Set Its 2026 Rate
On September 8, 2026, the Royse City council voted 6 to 0 to adopt Ordinance No. 26-09-1811. It sets the tax year 2026 rate at $0.6080 per $100, which the council minutes describe as "effectively a 6.3 percent increase in the tax rate." That 6.3 percent is measured against the no-new-revenue rate. The city's taxpayer impact statement shows the effect in dollars. At the no-new-revenue rate, the median homestead's city tax would have been about $1,812. At the adopted rate, it's about $1,926.
The same day, the Rockwall County Commissioners Court voted 5 to 0 to adopt a 2026 rate of $0.2620 per $100, effective October 1, 2026, Citizen Portal reported. A year earlier, the county's own budget notice listed a $0.2510 rate for fiscal year 2026.
Royse City ISD kept its total rate at $1.2552 for 2026-27, made up of $0.7552 for maintenance and operations and $0.5000 for debt service. That matches the prior year's adopted total. Even so, the district's September 15, 2026 notice says the rate "will raise more taxes for maintenance and operations than last year's tax rate."
| Taxing unit | 2025 rate per $100 | 2026 rate per $100 |
|---|---|---|
| City of Royse City | $0.578000 | $0.6080 |
| Rockwall County | $0.2510 | $0.2620 |
| Royse City ISD | $1.2552 | $1.2552 |
Two of the three rates went up and the third stayed the same. None of them came down, even though the city's median homestead value fell.
Parts of Royse City extend into Collin and Hunt counties, so the county line on a bill depends on the parcel. Collin Central Appraisal District lists Collin County's 2026 rate at $0.151414 per $100. The Hunt County Tax Office lists $0.333241 for tax year 2025. Two homes with the same Royse City address and the same price can have different county taxes.
The Market Underneath the Rates
Sales data shows the same pattern. According to the North Texas Real Estate Information System report produced by Texas A&M's Texas Real Estate Research Center, Royse City's single-family median in August 2026 was $325,000, compared with $328,990 in August 2025. Homes averaged 79 days on market, and inventory stood at 6.8 months. Rockwall County's August 2026 median was $444,990, down 1 percent from a year earlier, with 6.0 months of inventory.
The September 2026 report, released October 7, shows Royse City with 16 closed sales, 14 pending, 145 active listings, 83 days on market, and homes selling at 92.2 percent of list price. It had 6.7 months of inventory. The report also ranks cities by pending sales as a share of active listings. Royse City scored 9.7 that month, compared with 13.2 in Fate, 16.6 in Rockwall and 17.0 in Heath.
New construction is a big reason resale prices are holding flat. At Creekshaw, Highland Homes is advertising a $20,000 incentive, floor plans starting at $326,990 and six quick move-in homes. UnionMain has move-in-ready homes at Creekside, including one listed at $309,000. A resale home priced near the $325,000 median competes directly with those offers. The new homes behind those incentives become the "new improvements" line on next year's city worksheet. They will grow the tax base again while doing little to raise values on existing homes.
What This Changes When You Write an Offer
Put together, these numbers change how a buyer should negotiate in Royse City.
With 6.7 months of inventory and homes closing at 92.2 percent of list in September 2026, sellers are competing with each other and with builder incentives, which gives buyers room on price.
Tax rates are set by the taxing units, not negotiated between buyer and seller, and the Comptroller's rules above tie the 10 percent cap and homestead exemptions to the owner who qualifies for them. A lower purchase price lowers the base your taxes are calculated on, but the rates applied to that base went up for 2026.
The bill also depends on the parcel. The county rate depends on whether the parcel sits in Rockwall, Collin or Hunt County. Some subdivisions also carry public improvement district assessments. Creekshaw, for example, has a Royse City PID with its own assessment roll.
A practical way to compare two Royse City homes is to estimate each one's annual taxes from your expected purchase price and each parcel's current rates. Ignore the seller's last bill. Comparing that annual cost alongside the difference in list prices shows the real cost gap between the homes.
A Few Common Questions
If the median value went down, why would the city's tax on it go up? The city adopted a rate about 6.3 percent above the no-new-revenue rate. On the median homestead, that rate more than offset the lower value, moving the estimated city tax from about $1,909 to about $1,926.
Does the school district's rate staying the same mean school taxes stay flat? Not necessarily. Royse City ISD kept $1.2552 for 2026-27 but stated that the rate raises more maintenance and operations taxes than the prior year's rate did.
Will I keep the seller's 10 percent cap? According to the Comptroller, the limit applies to an owner who qualified for the homestead exemption in both the preceding and current year, and it takes effect January 1 of the year after that owner qualifies.
