9,966 tax returns (17,750 people including dependents) moved from Arizona to Texas in the 2022-2023 IRS migration year, carrying $800,298,000 in adjusted gross income.
Arizona to Austin is the heat move that looks contradictory on the weather page and makes sense the moment you realize Phoenix in August is actually hotter than Austin. Seventeen thousand people. Most of them are leaving metro Phoenix, landing in the Austin tech corridor, and accepting a slightly milder but longer humid summer in exchange for a softer grid story.
Why this move happens
Two reasons. First, the Phoenix heat peaked: 2023 and 2024 delivered multi-week runs above 110°F that changed the liveability conversation permanently for a lot of families. Second, the Austin tech pipeline pulled. Intel, Microchip, and ASU-adjacent engineering paths map cleanly onto Tesla, Samsung Taylor, and the Austin semi scene. The Arizona state income tax is relatively low, 2.5% flat, so the tax delta is modest, about $3,750 a year on a $150K household.
The math below is built for a typical two-person, one-house, one-car household clearing $150,000 gross. Your line items will move around. The Austin guide has a calculator you can run with your actual numbers; this page is the context the calculator cannot give you.
The money: Arizona vs. Austin, TX
Annual line items, $150K household, $450K home, one car. State averages, not quotes.
| Line item | Arizona | Austin, TX | Delta | Notes |
|---|---|---|---|---|
| State + local income tax | $3,750 | $0 | $-3,750 | $150K household. Texas has no income tax. |
| Property tax | $2,700 | $8,100 | +$5,400 | $450K home. Effective rate 0.60% vs 1.80%. |
| Homeowners + auto insurance | $3,282 | $6,684 | +$3,402 | State-average full-coverage auto plus HO3 homeowners. |
| Utilities (electric + gas + water) | $3,420 | $3,540 | +$120 | Monthly average multiplied by 12. |
| Sales tax (on $28K taxable spend) | $2,358 | $2,296 | $-62 | Combined state plus average local. |
| Annual total (these lines only) | $15,510 | $20,620 | +$5,110 |
On these five lines, the Austin move runs $5,110 more expensive per year than staying in Arizona. That ignores housing cost and a dozen smaller lines like HOA, childcare, and groceries.
If the five-line math does not land in your favor, the case for this move has to be made on housing cost, career opportunity, or lifestyle fit. Not taxes.
Housing: what Arizona money actually buys
Arizona property tax is unusually low for a Sunbelt state. Austin property tax is unusually high. On a comparable house, the annual carrying cost in Austin runs roughly $10K above Scottsdale. The pool cost is real. In Scottsdale it is baseline. In Austin it is a $60K-$90K add.
Where Arizona movers land professionally
The Arizona-to-Austin semi pipeline is the most concentrated professional cohort in this top ten. ASU and UT engineering alumni networks overlap. Phoenix-area Intel veterans map cleanly to Samsung Taylor and the NXP Austin fab.
Common landing employers for Arizona movers
- Samsung Taylor
- Tesla Gigafactory
- NXP Austin semi plant
- Intel-adjacent roles at Applied Materials and Lam Research
- Oracle
- Meta
- startup semi and battery operators
Climate shock: what changes when you leave Arizona
Summer high average in Arizona: 105°F. In Austin: 96°F. Winter low: 42° vs. 42°. Annual snowfall: 0" vs. 0.6".
Arizona is hotter and drier than Austin. Austin is 100+ days above 90F. Winter mild but ice storms 1-2x/decade.. Visit in August before you sign anything, not in March when the weather is flattering the city.
Phoenix summer and Austin summer are both brutal. Phoenix is drier and hotter by peak numbers. Austin is more humid and longer by total hours over 90°F. Arizona movers often report Austin feels worse in August despite the lower peak temperature, because the humidity does not give nights off.
Things Arizona movers do not expect
- Austin is wetter than Phoenix. Your skin will react. Your hair will react. The mold in closets is a new problem.
- The monsoon pattern disappears. Phoenix gets a summer storm season. Austin gets a few hard rains and then nothing for months. Different.
- The Latin food scene changes register. Phoenix is Sonoran and Norteño. Austin is Tex-Mex and interior Mexican. Both great, different.
- The yard is green. In Phoenix, desert landscaping is the default. In Austin, St. Augustine grass is the default. Different water bill, different maintenance profile.
- The college sports schedule flips. ASU is Pac-12 (now Big 12). UT is Big 12. The overlap is now substantial. Which is actually good for the Sun Devils in Austin.
The social rebuild
Arizona movers assimilate reasonably fast. The western-state casual register translates. The main friction is often religious. The LDS community in Arizona is substantial and Austin's is smaller and more spread out. If that is your framework, plan the ward search early.
The regret pattern, if it comes
Arizona regret in Austin is almost always about the humidity or the property tax. Scottsdale movers in particular tend to miss the ease of owning. Phoenix is still one of the most landscape-forgiving big-city markets in the country. Austin is not.
Return flow context
In the same year, 14,676 people moved from Texas back to Arizona. Roughly one person goes the other way for every 1 who make your move. That is the flow you are joining.
Return migration from Austin to Arizona is noticeable, largely driven by retirees and by Scottsdale professionals who miss the ease of ownership.
Five things a Arizona transplant wishes someone had told them
- The property-tax math is significantly harder in Austin than in Arizona. On a $700K house, expect $14,500 versus $4,200 in Scottsdale. Budget accordingly.
- You can buy a pool in Austin. It will cost you. In Scottsdale it was probably already there.
- Cedar fever lands in January and it is worse than any Phoenix allergy season you have experienced.
- The grid story in Texas is real. Get a generator or have a plan to leave during February cold snaps.
- The Phoenix-Austin flight is 2 hours, direct, and frequent. Use it in August.
The Arizona to Austin move, in four lines
- Volume. 17,750 people in a single tax year. This is a measurable wave.
- Net annual delta on five lines. $5,110 more per year for a $150K household. Housing is separate and usually larger.
- Climate. Summer is 9°F cooler than Arizona on average.
- Timeline. Eighteen to twenty-four months to feeling at home. Year one is mostly logistics.
