OVERVIEW
Arizona has a flat 2.5% income tax — the lowest flat rate in the US. California charges 1–13.3%, with a 9.3% marginal rate at $100,000 income. At $100K: Arizona residents pay approximately $2,098 in state tax; California residents pay approximately $4,911 — a saving of $2,813/year. At $150,000 the gap widens to $6,213/year. Arizona's 2.5% flat tax is the hidden gem—a $150,000 earner pays $3,348 vs California's $9,561, saving $6,213/year. The trap: Arizona summers are extremely hot, so air-conditioning costs add up. Choose Arizona if: you work remotely, tolerate heat, or want Phoenix's booming tech scene. Choose California if: you need coastal climate, LA/SF job markets, or refuse triple-digit summers.

FAQ

Frequently Asked Questions

How much will I save moving from California to Arizona?

A $100,000 earner saves roughly $2,813 annually (CA ~$4,911 vs AZ $2,098). At $150,000: saves $6,213 (CA $9,561 vs AZ $3,348). At $250,000: saves $13,013 (CA $18,861 vs AZ $5,848). 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 $2,098; CA charges $4,911.

What about the summer heat in Arizona?

Real talk: Phoenix summers are extremely hot, and air conditioning runs for months, which raises utility bills. Factor higher cooling costs into 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's effective rates vary by county, so check your county assessor. On a $500K home bought today, California's base 1% would be about $5,000/year before voter-approved local levies.

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.
