FAQ

Frequently Asked Questions

Is Wisconsin or Connecticut better for taxes?

Wisconsin has the lower income tax at every level, though the gap is modest at moderate incomes ($322/year at $100,000) and widens at higher incomes ($1,476/year at $500,000). Wisconsin also wins on property tax (1.32% vs 1.54%) and has no estate tax. Connecticut's advantage is proximity to New York City and typically higher salaries in finance, which can outweigh the tax difference for high earners in those fields.

How do Wisconsin and Connecticut tax long-term capital gains differently?

Wisconsin excludes 60% of net long-term capital gains from state taxable income, capping the effective state rate on gains at roughly 3.06% at the top bracket. Connecticut has no such exclusion — capital gains are taxed as ordinary income at the same rates as wages, up to 6.99%. This makes Wisconsin significantly more favorable for investors and business owners selling appreciated assets.

Does Wisconsin or Connecticut have an estate tax?

Neither Wisconsin nor most residents will face a state estate tax, but the mechanics differ: Wisconsin has no state estate tax at all, while Connecticut levies a 12% flat rate on estates above the federal exemption threshold (approximately $13.61-15 million for 2026). For high-net-worth families, Wisconsin has a clear structural advantage.

How do Wisconsin and Connecticut property taxes compare?

Wisconsin's average effective property tax rate is approximately 1.32%, below Connecticut's 1.54%. On a $400,000 home, that's roughly $880/year less in Wisconsin — both states have relatively high property taxes by national standards, but Wisconsin is meaningfully cheaper.
