Compare taxes and see how much you save moving from Arizona to Texas
Arizona and Texas are both Sun Belt favourites for domestic migration — but their tax structures produce surprising results when compared properly. Texas has no income tax (vs Arizona's 2.5% flat rate since 2023), but Arizona's property tax rate of approximately 0.63% is dramatically lower than Texas's 1.63%. At $100,000 income on a $400,000 home: Arizona income tax costs $2,500, but Arizona saves approximately $4,000 in property taxes vs Texas. Net result: Arizona's total state tax burden is approximately $1,500/year LOWER than Texas's for homeowners. At higher incomes (above $200,000), Texas's income tax zero-rate advantage surpasses the property tax differential, making Texas cheaper. Arizona's 2.5% flat rate (one of the lowest income tax rates in the nation) combined with very low property tax creates one of the most competitive total tax environments in the US.

The key: Arizona's 0.63% property tax is dramatically below Texas's 1.63%. On a $400,000 home, Arizona saves $4,000/year in property taxes vs Texas — more than offsetting the $2,500 Arizona income tax at $100,000 income. The crossover point: around $250,000 income (for a $400,000 home), Texas's income tax zero-rate advantage ($6,250 savings) matches Arizona's property tax advantage ($4,000). Above $300,000+ income on a typical home, Texas becomes cheaper overall.
Arizona's income tax is a flat 2.5% on all taxable income as of 2023. Arizona's transition to a flat rate was driven by Proposition 132 (2022), which capped the rate at 2.5%, effectively striking down the Proposition 208 3.5% surcharge on high earners that had briefly created a 4.5% top rate. The current 2.5% applies to all Arizona taxable income above the standard deduction. Arizona's standard deduction for 2024 is approximately $13,850 single / $27,700 married filing jointly. So a $100,000 earner (single) pays approximately 2.5% × ($100,000 - $13,850) = $2,154. Arizona's 2.5% is one of the lowest income tax rates of any state that still has income tax.
Austin is the premier tech hub: Tesla HQ, Apple's Austin campus, Dell, and hundreds of startups — genuine ecosystem depth. Dallas is strong in enterprise tech, finance, and telecom (AT&T, Nokia, Texas Instruments). Phoenix is emerging rapidly: TSMC's $65B semiconductor fab expansion, Intel's Chandler campus, and financial services giants (JPMorgan, Citi, American Express) are transforming Phoenix into a serious tech and finance hub. Tax-wise: Arizona (Phoenix) is very competitive — 2.5% income tax + low property tax; Texas (Austin/Dallas) has zero income tax but very high property tax. For tech professionals on $150,000–250,000 salaries owning a $500,000 home, Arizona and Texas produce nearly identical total tax burdens.
Arizona taxes most retirement income at the flat 2.5% rate, with some exemptions. Arizona does not tax Social Security benefits. Arizona exempts up to $2,500 of US government/military retirement income. Pension income from Arizona state or local government is taxed. IRA and 401(k) distributions are taxed at 2.5%. Arizona also offers a small subtraction for qualifying retirement income (pension/annuity income from qualified plans) up to certain thresholds for older residents. Overall, Arizona's 2.5% flat rate makes retirement income relatively inexpensive to tax — but Texas's zero rate is still better for retirees with significant IRA/401(k) distributions.
It is a real long-term concern but currently managed. Arizona's water supply relies on a three-source system: the Colorado River (via CAP), groundwater aquifers, and reclaimed water. The Colorado River's declining water levels have resulted in CAP water cuts (Tier 1 and Tier 2 shortages declared since 2021), reducing availability. Arizona has invested heavily in water recycling and conservation — Phoenix and Tucson have among the most advanced water recycling programmes in the US. Most homes have secure water supplies for 100+ years under current conservation plans. However, rapid population growth and continued drought conditions are creating genuine long-term pressure. Property buyers should research water availability, especially in outlying communities relying solely on groundwater.
