The tax rate difference between Prosper ISD and Denton ISD has narrowed to just 0.72 cents per $100 of assessed value. For the average Windsong Ranch home, this translates to approximately $83 per year — less than $7 per month — to align tax dollars with where students actually attend school.
| Component | Prosper ISD | Denton ISD | Difference | Notes |
|---|---|---|---|---|
| M&O Rate (Maintenance & Operations) | $0.7141 | $0.7269 | -$0.0128 | PISD is lower |
| Tier 1 (MCR - Compressed) | $0.5758 | — | — | TEA mandated |
| Tier 2 (Golden + Copper) | $0.1383 | — | — | Voter approved |
| I&S Rate (Interest & Sinking/Debt) | $0.5000 | $0.4800 | +$0.0200 | Bond obligations |
| TOTAL TAX RATE | $1.2141 | $1.2069 | +$0.0072 | 0.6% higher |
With continued state-mandated tax rate compression, it is likely that Denton ISD will become more expensive compared to Prosper ISD over time. PISD's lower M&O rate ($0.7141 vs $0.7269) positions Prosper taxpayers favorably as compression continues. The current $0.0072 difference may shrink further or even reverse in future years.

PISD Overview uses 349 homes (current) with 420 at build-out. Our model's 466 figure from Denton CAD includes green lots/common areas that will not have homes built on them. The actual build-out of 420 homes aligns with PISD's analysis. Both datasets support the same conclusion: minimal tax impact for homeowners.

Source: PISD 2025-2026 Adopted Budget — State Revenue $201,465,591 ÷ 32,832 ADA = $6,136/student; Total Expenditures $427,215,623 ÷ 32,832 ADA = $13,012/student
PISD already receives ~$1.68M in state funding for the 274 Windsong students (they're already in ADA). What PISD does NOT receive is the $6.5M in local property tax revenue — that currently goes to Denton ISD, which educates zero of these students. Annexation simply redirects local tax dollars to follow the students.

Our model uses a higher total assessed value ($537.7M vs $474.7M) because the Denton CAD data includes all platted lots. The actual build-out is 420 homes, which aligns with PISD's analysis. The higher TV in our model produces proportionally higher calculated revenue.
