The largest active-adult community in Texas. 7,500+ homes, 3 golf courses, no state income tax — and a school tax freeze that saves seniors thousands every decade. Here is the math nobody else does.
Talk to a Local ExpertSun City Georgetown is not just the largest 55+ community in Texas — it is one of the largest in the United States. Del Webb broke ground here in 1996 on 5,300 acres, 35 miles north of Austin. Today 7,500+ homes are occupied; build-out is approved for 10,550. That scale produces something smaller communities cannot replicate: critical mass for clubs, sports leagues, and a social calendar dense enough to fill every day if you want it.
The surrounding Georgetown/Round Rock corridor reinforces the case. Georgetown's historic square — repeatedly cited as the most beautiful town square in Texas — is 10 minutes from Sun City's gate. Baylor Scott & White and St. David's hospitals are within city limits. Costco, H-E-B, and Round Rock Premium Outlets are 20–25 minutes away. And when I-35 is gridlocked, the SH 130 toll road connects to Tesla Gigafactory and Austin-Bergstrom airport without touching the interstate.
Georgetown ISD's 2025-26 combined rate is $1.0506 per $100 of assessed value — the largest portion of your total property tax bill. Once you turn 65 and file the over-65 homestead exemption with Williamson County Appraisal District, your Georgetown ISD tax bill is permanently frozen at its current-year amount. Property values can rise 20% over the next decade; your school tax bill cannot increase by a penny. File within 30 days of closing. This saves the average Sun City buyer an estimated $4,000–$8,000 over a 10-year ownership period compared to a non-exempt neighbor in the same home.

| Georgetown ISD | $1.0506 | $10,000 off AV + school tax FROZEN at 65 |
| City of Georgetown | ~$0.374 | City taxes also frozen at 65 |
| Williamson County | ~$0.356 | $125,000 exemption for 65+ (one of TX's most generous) |
| Combined (approximate) | ~$1.78 / $100 | Statewide homestead: $140,000 off AV |

Market value: $350,000. Statewide homestead exemption removes $140,000 → assessed at $210,000. Over-65 school exemption removes another $10,000 → school district taxes on $200,000. County exemption removes $125,000 → county taxes on $85,000. Rough all-in annual bill for a 65+ owner: approximately $3,200–$3,800/year — and the school portion never rises again. Compare that to a comparable home in suburban Phoenix (~$2,400, no income protection) or suburban Chicago (~$8,000–$12,000 with full income tax exposure).
