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.
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.
Understanding Each State
Wisconsin
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.

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.

Key Comparison Points
Income tax structure: Wisconsin has a progressive income tax (3.5% – 7.65%), while California has a progressive income tax (1% – 13.3%).
Beyond income tax: State tax comparisons should also consider property tax rates, sales tax, and cost of living. A state with no income tax may have higher property or sales taxes that offset the savings.
SALT deduction cap: Under OBBBA (2025+), the federal SALT cap is $40,000, phasing out above $500,000 MAGI toward a $10,000 floor. This limits the federal tax benefit of living in a high-tax state, so the gross state tax difference remains close to the net difference for most earners — especially high earners inside the phaseout.
