In Frisco, the School District Line Moves Your Tax Bill More Than City Hall Does

Frisco's 2026 headline is that the City Council held its property tax rate flat at $0.425517 per $100 of valuation. It approved the rate on September 15 for the fiscal year that began October 1, 2026. For a buyer comparing homes, that number is the least useful one on the bill. Two Frisco homes at the same price, both inside city limits and both paying the same city rate, can end up about $800 a year apart. The difference comes from which school district's line the house sits on.

Collin County mails property tax statements in October, and they are due on receipt. Payment without penalty and interest runs through January 31. Statements are going out right now, so this is when the tax line on a listing and the bill the next owner actually gets are most likely to differ.

A flat rate still produced a bigger bill

Start with the city. It says the average taxable home value in Frisco is about $608,520. That puts the average 2026 city tax bill at $2,589.36, about $8 a month more than last year, at an unchanged rate. Community Impact explains how that happens. The city can collect more revenue without raising its rate when taxable values climb through new construction and higher property values.

Frisco ISD made the same move. As Community Impact reported, trustees kept the 2026-27 rate at $1.0194 per $100 on August 17. District documents still projected that the average homeowner's bill would rise by $141, because the average residence taxable value went up 2.5% to $565,084 in 2026.

In both cases, holding the rate steady still raised the typical bill. Taxable value drives the bill as much as the rate does, and the school district usually supplies the biggest rate on a Frisco bill.

The line that moves more money than the city's change

Frisco isn't one school district. The City of Frisco has reported that more than seven square miles of Prosper ISD territory lie inside its city limits. According to Community Impact, Prosper ISD adopted a 2026-27 rate of $1.2011 per $100, down from $1.2141 the year before. Even after the cut, it sits about 18 cents per $100 above Frisco ISD.

Here are the 2026 rates that apply in and around Frisco, from the adopting bodies and the appraisal districts:

Lewisville ISD and Little Elm ISD appear in Denton County's 2026 rate table and serve areas around Frisco. Confirm which district covers any particular address through the appraisal district instead of assuming from the mailing address.

To see what an 18-cent gap means in dollars, take a home with $460,000 of school-taxable value. That's roughly a $600,000 appraisal minus the $140,000 school homestead exemption the state requires districts to grant on a qualified residence homestead. At Frisco ISD's rate, the school portion comes to about $4,689. At Prosper ISD's rate, it comes to about $5,525. That's a difference of roughly $836 a year, or close to $70 a month, between two homes with the same value in the same city. These figures are an illustration, not a quote for any specific property.

That $70 a month is more than eight times the $8-a-month increase the city attributes to its own 2026 budget. Same city, same city rate, and the school boundary does most of the separating.

Where Prosper ISD shows up inside Frisco

The Prosper ISD portion of Frisco isn't a technicality on a map. Community Impact reported in April 2025 that Frisco added a school zone in the Dove Creek neighborhood after Prosper ISD opened a middle school, to help students cross Glade Hill Drive. Prosper ISD lists Hays Middle School at 14441 Hillcrest Road, Frisco, TX 75035.

That's the practical point for buyers. A Frisco address, a 75035 ZIP code and Frisco city services can all sit on top of a Prosper ISD tax line. When two listings in nearby neighborhoods carry similar prices and noticeably different tax estimates, the school district boundary is the first thing to check. This is purely about which rate applies. It says nothing about the schools themselves.

A "Frisco" name on the entrance sign is not the taxing map

The county line works the same way, on a smaller scale. Collin County's 2026 rate is $0.151414 per $100, and Denton County's is $0.183394. On the illustration above, that gap is about $150 a year before any county exemptions.

Special districts can add a whole extra line. Frisco West WCID, a water control and improvement district, appears in Denton County's 2026 table at $0.50 per $100, up from $0.49 in 2025. The district's own site lists its communities as Frisco Hills, Frisco Ranch and The Preserve at Frisco Ranch. A neighborhood can carry "Frisco" in its name and still sit under a different combination of city, school district and special district than a home a few miles east. The appraisal district's jurisdiction list for the parcel shows which taxing units bill it.

Public improvement districts work differently again. Collin County's tax rate summary notes that a PID charges an assessment set by the district, not an ad valorem tax rate. So a PID won't show up in a rate comparison like the table above, even when it adds to a homeowner's annual cost.

The tax line on a listing belongs to the last owner

The jurisdiction question sets the rates. Exemptions decide how much value those rates hit, and exemptions follow the owner, not the house.

Collin CAD's 2026 table shows that the City of Frisco grants a 20% local homestead exemption. It also grants $80,000 over-65 and disabled-person exemptions, along with a tax freeze in both categories. On the school side, the state's $140,000 homestead exemption rises by another $60,000, to $200,000 combined, for eligible homeowners who are 65 or older or disabled. Collin CAD lists those state amounts for both Frisco ISD and Prosper ISD.

A long-time seller with a homestead, an over-65 exemption and a frozen school tax can show a tax figure that has little to do with what a buyer's first full year will look like. Investors buying a Frisco home as a rental face the same issue from the other side, because a homestead exemption applies to a residence homestead. When a monthly payment estimate uses the tax amount printed on a listing, the payment can be off by hundreds of dollars a month before anyone has done anything wrong.

Before comparing two Frisco homes on monthly cost, these are the pieces to pull for each address:

• School district: Frisco ISD, Prosper ISD or another district, from the appraisal district record.
• County: Collin or Denton, which also determines which appraisal district values the home.
• Special districts: any WCID, MUD or PID tied to the parcel, and whether it's a rate or a fixed assessment.
• Current exemptions: which exemptions the seller holds, and whether a 65+ freeze is part of the current bill.
• The 2026 adopted rates: the rates set this fall, not last year's statement.

Rates reset every year, on both sides of the line

The gap in this post is a 2026 gap. Prosper ISD lowered its rate this year. Lewisville ISD dropped from $1.1178 to $1.0778. Frisco ISD and Little Elm ISD held steady, and Collin County went up slightly. Each taxing unit votes on its rate every summer or fall, so the distance between any two Frisco addresses can shrink or widen from one year to the next. Frisco ISD's own documents show its maintenance and operations rate falling from $1.17 in 2018 to $0.7494 by 2025. That's a reminder that these rates do move.

The boundary itself stays put while the rates move. Buying a home inside Frisco means buying into a specific set of taxing units for as long as you own it.

FAQ

Did Frisco raise its property tax rate for 2026? No. The city rate stays at $0.425517 per $100 for fiscal year 2026-27. Community Impact describes this as nine years without a rate increase, and the City of Frisco notes it's the third straight year at this exact rate, after a cut.

When are 2026 property taxes due in Collin County? Statements go out in October and are due on receipt. Collin County's FAQ says taxes can be paid without penalty and interest through January 31 and become delinquent on February 1. January 31, 2027 falls on a Sunday, so confirm the exact final date with the Collin County Tax Assessor-Collector.

Does a Frisco address mean Frisco ISD? Not always. More than seven square miles of Prosper ISD lie inside Frisco city limits, according to the City of Frisco.
