FAQ

Frequently Asked Questions

How much will I save moving from California to Arizona?

A $100,000 earner saves roughly $3,262 annually (CA ~$5,762 vs AZ $2,500). At $150,000: saves $7,241 (CA $10,991 vs AZ $3,750). At $250,000: saves $19,971 (CA $22,471 vs AZ $6,250). Arizona's 2.5% flat tax means the higher your income, the more you save vs California's progressive 13.3% top rate.

What's Arizona's 2.5% flat tax?

Arizona simplified its tax system to a single 2.5% rate on all taxable income in 2023—one of the lowest flat rates in the US. No brackets, no complexity. Compare to California's 9 brackets ranging from 1% to 13.3%. On $100,000 income: AZ charges $2,500; CA charges $5,762.

What about the summer heat in Arizona?

Real talk: Phoenix averages 100°F+ for 100+ days/year, hitting 115°F+ regularly. AC runs constantly June-September, adding $300-500/month to utility bills. Factor $3,000-5,000/year in additional cooling costs against your tax savings. Many Arizonans 'snowbird' elsewhere for summer—can you?

Which state has better property taxes?

California wins thanks to Prop 13: property tax is capped at 1% of purchase price, increasing max 2%/year regardless of market value increases. Arizona has no cap—property taxes average 0.62% but reassess to current market value. On a $500K home: CA = $5,000/year (locked); AZ = $3,100/year (can rise).

Can I work remotely from Arizona for a California company?

Complicated. California aggressively claims tax on income 'sourced' to CA. If your employer has CA offices and you occasionally visit, CA may pursue you. Safest approaches: work for AZ-based or fully remote company, or negotiate a new employment contract establishing AZ as your work location. Consult a cross-state tax specialist.
