Why the difference
You'd save $2,271/year ($189/month) in Arizona vs California.
Tax structure
California uses progressive brackets up to 13.3%, while Arizona has a flat 2.5% state income tax.
Effective rate at your income
At $100,000, Arizona's effective state rate is 2.1% vs 4.4% in California — a 2.3 percentage point gap.
Tip: California's progressive brackets mean your effective rate is much lower than 13.3% for most earners. At $100,000, the effective state rate is approximately 5.8%. Consider maximizing 401(k) contributions and HSA to reduce California-taxable income.
Tip: In a progressive-bracket state, pre-tax 401(k) and HSA contributions reduce your state tax bill along with federal tax. If you are near a bracket boundary, an additional contribution can drop you into a lower state bracket.

Understanding Each State
California
California has the highest top marginal state tax rate in the US at 13.3%, with progressive brackets starting at 1%. An additional 1% Mental Health Services Tax applies to incomes over $1 million. Despite high taxes, California's economy — tech, entertainment, agriculture — attracts top talent globally. Under OBBBA (2025+), the SALT deduction cap rose to $40,000 ($20,000 MFS) but phases out $1-for-$1 above $500,000 MAGI ($250,000 MFS) toward a $10,000 floor — so high-income California itemizers see only partial federal relief.

Arizona
This state uses a progressive income tax system with multiple brackets, similar to the federal system. Only the income within each bracket is taxed at that rate, so your effective state rate is lower than the top bracket. Tax planning strategies include maximizing pre-tax retirement contributions to reduce state-taxable income.
