Two of the Southwest's top retirement destinations, compared on taxes, 55+ community depth, climate, and cost. Real numbers, no lifestyle fluff.
| Tax Factor | St. George, UT | Scottsdale, AZ |
|---|---|---|
| Property tax effective rate | ~0.37% | ~0.55% |
| Annual tax on $500K home | ~$1,850 | ~$2,750 |
| Monthly tax on $500K home | ~$154 | ~$229 |
| Income tax rate | 4.5% flat | 2.5% flat |
| Social Security tax | Taxed (but credit eliminates for most) | Exempt |
| Pension income tax | 4.5% | 2.5% |
| 10-yr property tax savings on $500K (vs. each other) | +$11,000 vs. AZ | — |
Arizona's 2.5% flat rate beats Utah's 4.5% on pension and IRA income. But Utah's lower property taxes partially offset that. At $80K annual income with $500K home: the Arizona income tax advantage is ~$1,600/year; the Utah property tax advantage is ~$900/year. Net: Arizona wins by ~$700/year at this profile. At lower incomes where Utah's SS credit fully applies, the gap narrows or reverses. Run your specific numbers.
| Category | St. George, UT | Scottsdale, AZ |
|---|---|---|
| Largest 55+ community | SunRiver (2,600+ homes) | Sun City Scottsdale (20,000+ homes) |
| Total 55+ community count | ~12–15 options | 50+ options across metro |
| New construction 55+ | SunRiver Firelight (active) | Multiple builders active |
| Price range (55+ communities) | $280K–$3M | $200K–$5M+ |
| HOA range | $100–$600/mo | $200–$800+/mo |
Scottsdale's active adult community depth is significantly larger than St. George's — the Phoenix metro is the largest 55+ market in the country. St. George's market is more focused, with SunRiver as the dominant option and a smaller supporting cast. For buyers who want to choose between many large established 55+ communities, Scottsdale wins on depth. For buyers who want a smaller city with a tight geographic community, St. George has appeal that Scottsdale's sprawl doesn't.
Both markets are desert. Both are hot in summer. The differences matter for lifestyle planning:
| Climate Factor | St. George (2,530 ft elev.) | Scottsdale (1,219 ft elev.) |
|---|---|---|
| Summer highs (July avg) | ~102°F | ~105°F |
| Winter lows (Jan avg) | ~30°F (frost possible) | ~44°F (rarely freezes) |
| Snow | Light snow possible (1-3x/year) | Essentially none |
| Outdoor season | Oct–May best | Oct–April best |
| Proximity to mountains | 5 min to red rock hiking, ski resorts 1.5 hrs | 30 min to Sedona, ski resorts 2 hrs |
St. George is meaningfully cooler in summer than Scottsdale — which matters for the 3–4 months when outdoor activity diminishes for both. The higher elevation and proximity to Zion, Bryce, and the Grand Circle parks is a differentiator that serious outdoor recreation buyers cite repeatedly. Scottsdale's warmer winters are an advantage for the 10% of days where St. George gets frost.
