Property Taxes in Collin and Denton County for Prosper Buyers

Property taxes in the Prosper and Celina area are not a single rate — they are a stack of four or more separate levies that combine on one annual bill. For FY 2026–27, Prosper ISD approved a rate of $1.2011 per $100 of valuation, the Town of Prosper proposed a city rate of $0.505000 per $100, and Collin County adds its own levy on top. Depending on the exact parcel, MUD and other special-district taxes can push the total well above $2.00 per $100, which is why two similarly priced homes in neighboring subdivisions can carry meaningfully different monthly tax payments.

Key Takeaways

• Prosper ISD’s board-approved FY 2026–27 tax rate is $1.2011 per $100 of valuation, down slightly from $1.2141 the prior year, making it the single largest layer on most Prosper-area tax bills.
• A compiled Collin County tax map shows Prosper city + Prosper ISD combined at $1.9497 per $100 versus Celina city + Celina ISD at $2.0159 per $100 for Tax Year 2025, before county and special-district levies are added.
• Collin County’s own levy is $0.1493 per $100; Denton County’s 2026 no-new-revenue rate is $0.179909 per $100, meaning county-level taxes are a smaller slice but still real money on a $400,000+ home.
• Municipal utility district (MUD) taxes can push a parcel’s total rate to $2.3347 per $100 or higher — one Collin County example shows Prosper ISD + Collin County MUD #01 at exactly that figure.
• Every Prosper-area buyer should confirm the full stacked rate for the specific address before locking in a budget, because the difference between the lowest and highest combined rates in this market can translate to hundreds of dollars per month.

Why Does Your Property-Tax Bill Have So Many Layers?

This is the question I get from almost every buyer I work with in Prosper and Celina. They see a tax estimate online and assume it’s one flat rate. It isn’t.

In Texas, property taxes are levied by each individual taxing unit that has jurisdiction over your parcel. On a typical Prosper-area home, those units include the county, the city or town, the school district, and potentially one or more special districts like a MUD, a hospital district, or a community college district. Each unit sets its own rate. Those rates are then added together and applied to your home’s assessed (taxable) value.

The Collin County Tax Assessor’s office, which updated its 2026 tax rate page on September 4, 2026, lists all the taxing units operating within the county, including Celina. That page is your ground truth for what applies to a specific address on the Collin County side.

The school district layer is the biggest one

School taxes are almost always the single largest line on a North Texas property tax bill, and Prosper is no exception. The Prosper ISD Board of Trustees approved a tax rate of $1.2011 per $100 of assessed value for the 2026–27 school year at its August 24, 2026 meeting — down slightly from the prior year’s $1.2141 rate, but still the largest single component of most Prosper-area bills.

On a home with a $400,000 taxable value (after any exemptions), that rate works out to roughly $4,804 a year in school taxes alone — before the city, county, or any special district is added in. Homes inside Celina ISD or other neighboring districts will see a different figure, so it’s worth confirming which school district actually serves the specific address you’re considering, since district boundaries don’t always match city limits.

The city and county layers come next

The Town of Prosper set its city tax rate at $0.505000 per $100 of assessed value at its August 11, 2026 council meeting. Layered on top of that is Collin County’s levy of $0.1493 per $100, which applies to any parcel inside Collin County regardless of which city or ISD it falls under.

Properties on the Denton County side of the market — including parts of Celina and other nearby areas — see a different county rate. Denton County’s 2026 no-new-revenue rate is $0.179909 per $100, with a voter-approval rate of $0.191201 per $100. Which of those two figures ultimately applies depends on decisions made during the county’s budget process, so it’s worth checking the current adopted rate rather than assuming the lower figure.

How Do the Combined Rates Compare Across Prosper, Celina, and Nearby Areas?

Once you stack the school, city, and county layers together (and add any special district that applies), the total combined rate is what actually determines your bill. Here’s how the combined rates compare across the areas I work in most, based on Tax Year 2025 figures from the DFW Tax Map:

That gap between Prosper and Celina’s combined rates — about $0.0662 per $100 — works out to roughly $330 a year in additional property tax on a $500,000 home. It’s a meaningful number to factor into a monthly budget, but it’s not dramatic enough on its own to rule a community in or out; most buyers weigh it alongside lot size, amenities, and commute. For more on how small rate differences add up over time, see my earlier post, “The $280 Shift in Affordability Every Homebuyer Should Know.”

The bigger jump shows up when a MUD is involved. A parcel taxed under Prosper ISD plus a Collin County Municipal Utility District can see a combined rate of $2.3347 per $100 — nearly 20% higher than a comparable home in a subdivision without a MUD. That difference is large enough to change a buyer’s monthly payment by a meaningful margin, which is why I always flag MUD status early when we’re touring new-construction communities.

What About the Homestead Exemption?

Texas offers a homestead exemption that reduces the taxable value of a primary residence, which lowers the tax bill calculated from the rates above. The exemption is filed with the appraisal district in the county where the home is located — Collin Central Appraisal District or Denton Central Appraisal District, depending on where the property sits — and it isn’t automatic.

If you close on a home this year, you’ll file for the homestead exemption the following January, once you’ve actually lived in the home as your primary residence on January 1 of that tax year. It’s a step that’s easy to forget after a move, but skipping it means paying tax on the full assessed value instead of the reduced, exempted amount.

How Taxes Translate to a Monthly Payment

Most Prosper-area buyers pay their property taxes through an escrow account attached to their mortgage, meaning the annual tax bill is divided by twelve and collected as part of the monthly payment along with principal, interest, and insurance. That’s convenient, but it also means a change in the tax rate or assessed value can raise your monthly payment even if your loan terms never change.

For a rough sense of scale, a third-party compilation from Property Tax By State put Collin County’s median effective property tax rate at 1.58%, with a 2024 median tax bill of $7,521 on a median home value of $475,600. That figure is a compiled estimate, not an official county number, and it blends every city and ISD in the county together — so treat it as a ballpark, not a substitute for calculating the actual stacked rate at a specific address.

Your specific number depends on the exact combination of city, ISD, county, and any special district that applies to the address you’re considering — there’s no substitute for pulling the real stacked rate before you commit to a budget. I’ve also written about why homes feel so expensive in North Texas right now, which covers some of the other factors driving monthly payments beyond taxes alone.

I walk my clients through a full cost breakdown — taxes, insurance, HOA dues, and MUD fees where they apply — before we ever write an offer, so there are no surprises at closing or in that first mortgage statement. If you’d like to see exactly what a specific Prosper or Celina address would cost you in property taxes, I’m happy to walk through it together.

Frequently Asked Questions

What is the current Prosper ISD tax rate for 2026–27?

The Prosper ISD Board of Trustees approved a rate of $1.2011 per $100 of assessed value for the 2026–27 school year at its August 24, 2026 meeting, down from $1.2141 the prior year.

What taxing units show up on a Collin County property tax bill?

A typical Collin County property tax bill combines the school district, the city or town, the county itself, and, in some subdivisions, a municipal utility district (MUD), hospital district, or community college district. Each unit sets its own rate, and all of them are added together to produce the total you owe.

Do MUD taxes apply in Celina and Prosper-area subdivisions?

Some newer subdivisions in and around Prosper and Celina are served by a municipal utility district, which levies its own tax on top of the city, county, and school district rates. Not every subdivision has one, so it’s important to confirm MUD status before comparing two communities on price alone — a lower list price can be offset by a materially higher combined tax rate.

Is Denton County’s property-tax burden lower than Collin County’s for Prosper-area buyers?

At the county level alone, Denton County’s 2026 no-new-revenue rate of $0.179909 per $100 is higher than Collin County’s $0.1493 per $100. But the county rate is only one layer of a much larger stacked rate, so it shouldn’t be used on its own to judge which side of the market is more affordable — the city and school district rates matter more to the total bill.

How do Prosper and Celina property tax rates compare?

Combined city-and-ISD rates run about $1.9497 per $100 in Prosper versus $2.0159 per $100 in Celina for Tax Year 2025 — a difference of roughly $330 a year on a $500,000 home. That gap largely reflects Celina’s faster growth, newer school facilities and infrastructure being built out to serve its expanding population, not a difference in what either community offers buyers.
