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.

Louisiana
This state uses a flat income tax rate, meaning the same percentage applies to all taxable income regardless of how much you earn. This simplifies tax planning but means there is no bracket benefit for lower earners. The effective rate is very close to the headline rate after deductions.

Key Comparison Points
Income tax structure: Wisconsin has a progressive income tax (3.5% – 7.65%), while Louisiana has a flat income tax (3% flat).
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, the 2026 federal SALT cap is $40,400, phasing out above $505,000 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.
