COLLIN COUNTY, Texas — Homeowners in one of North Texas’ fastest-growing suburban counties will see a higher county property tax rate beginning Oct. 1 after the Collin County Commissioners Court approved its first rate increase in more than three decades.
Commissioners approved the fiscal year 2027 budget and tax rate as Collin County prepares to begin its new fiscal year on Oct. 1.
The county property tax rate will increase from approximately $0.149 per $100 of assessed property value to $0.151 per $100. The change marks the first time Collin County has raised its property tax rate since 1993.
For people considering a move to North Texas, the decision is particularly relevant because Collin County includes or encompasses parts of some of the Dallas-Fort Worth region’s most popular relocation destinations, including Plano, Frisco, McKinney, Allen, Prosper, Celina and Melissa.
What the Increase Could Mean for Collin County Homeowners
Although the change in the tax rate is relatively small, it comes as property values across Collin County have also increased.
County budget figures put the median home value used for fiscal 2027 at approximately $517,911, compared with $480,773 in the previous fiscal year.
For a median-value home receiving a homestead exemption, estimated county property taxes would increase from approximately $682 to $745 annually, a difference of about $63.
The higher rate is expected to generate approximately $16.3 million in additional property tax revenue for Collin County.
For newcomers, however, there is an important distinction: the Collin County property tax represents only one portion of a homeowner’s total property tax bill.
Depending on where a home is located, property owners may also pay taxes to a city, school district, Collin College and other local taxing entities or special districts.
That means homebuyers comparing communities across Collin County should examine the combined property tax obligations associated with a specific home rather than looking at the county tax rate alone.
A Break From More Than Three Decades of Tax-Rate History
The fiscal 2027 decision represents a notable change for Collin County.
For fiscal year 2026, the county maintained a property tax rate of approximately $0.149343 per $100 of valuation, continuing a decades-long period without an increase in the county rate.
That did not necessarily mean individual homeowners saw unchanged tax bills. Property taxes can increase even when the tax rate remains the same if a property’s taxable value rises.
The fiscal 2027 change puts additional attention on both sides of the property-tax equation: the value assigned to a property and the tax rates applied to that value.
Why Property Taxes Matter When Moving to Collin County
For families relocating to North Texas, property taxes can have a significant effect on the actual monthly cost of owning a home.
Collin County continues to attract newcomers with its expanding suburban communities, new housing developments, major employment centers, schools, shopping and entertainment districts, and access to the broader Dallas-Fort Worth economy.
But a home’s purchase price tells only part of the affordability story.
Households moving from another state—or even another part of Texas—should factor property taxes, homeowners insurance, HOA assessments and commuting expenses into their housing budgets.
Property taxes deserve particular attention because the total rate can vary substantially between neighboring communities and even between different developments within the same city.
A buyer considering a $500,000 home in one Collin County community could therefore face different annual property-tax costs than someone purchasing a similarly priced home elsewhere in the county.
What Newcomers Should Know Before Buying
The new Collin County property tax rate takes effect as the county begins its 2027 fiscal year on Oct. 1, 2026.
For people planning a move to Plano, Frisco, McKinney, Allen, Prosper, Celina, Melissa or elsewhere in Collin County, the increase is another reminder to calculate the complete cost of homeownership before choosing a community.
When comparing homes, newcomers should consider requesting an estimate of the property’s annual taxes based on its expected taxable value and the applicable taxing jurisdictions.
A house with a lower asking price does not always translate into a lower monthly housing expense once taxes, insurance, HOA fees and other ownership costs are considered.
As Collin County continues to grow, understanding those local costs can help newcomers make more informed comparisons between communities across the Dallas-Fort Worth Metroplex.
