Wondering how much house you can afford with your net pay?
Mortgage Loan CalculatorConnecticut runs one of the more aggressive progressive tax structures in the Northeast, with seven brackets that climb all the way to a 6.99% top marginal rate for high earners — among the higher state rates in the country, though still below neighboring New York City's combined state-and-city burden. Unlike a flat-tax state, Connecticut's brackets mean your effective rate is usually well below that 6.99% headline number unless you're firmly in the top bracket (over roughly $500,000 for single filers, higher for joint filers). The state also has a unique "recapture" provision for high earners that phases out the benefit of lower brackets entirely, effectively flattening the tax at the top for very high incomes. Compared to neighbors, Connecticut is meaningfully more expensive than income-tax-free New Hampshire and somewhat higher than Massachusetts's near-flat rate, but it doesn't stack a separate city tax on top the way New York City does. Connecticut also has no local income taxes at the municipal level, so the state rate is generally your full income-tax picture — property taxes, not income tax, tend to be where Connecticut residents feel the biggest local bite.

Everything you need to know about using this calculator and the math behind it.
How it Works
Strips away estimated federal and Connecticut state taxes plus common deductions from your gross salary to reveal your actual take-home (net) pay.
The Formula
Net Pay = Gross Pay − (Federal Tax + Connecticut State Tax (6.99%) + FICA + Pre-tax Deductions).
Pro Tip
Check whether your city or county adds any local wage tax on top of the 6.99% state rate before you finalize your budget.
Frequently Asked Questions
What is Connecticut's top income tax rate? +
Connecticut's top marginal state income tax rate is 6.99%, applied to the highest bracket of income for top earners. The state uses seven progressive brackets starting around 2% for the lowest income and stepping up through several intermediate rates before reaching 6.99%, so most filers pay a blended effective rate well below the top marginal figure.
How does Connecticut compare to New York and Massachusetts? +
Connecticut's 6.99% top rate is close to New York State's top rate but Connecticut doesn't add a separate city income tax the way New York City does, which can push combined NYC rates above 10%. Massachusetts runs a near-flat 5% (plus a 4% surtax on income over $1 million), generally a bit lower than Connecticut for most income levels.
Does Connecticut have local or city income taxes? +
No. Connecticut does not levy any municipal or local income taxes — the 6.99% top state rate (or your applicable bracket) is your full income tax burden. Connecticut towns instead rely heavily on property taxes for local revenue, which are among the higher property tax rates in the country.
What is Connecticut's tax "recapture" provision? +
Connecticut phases out the benefit of its lower tax brackets for high-income filers through a recapture mechanism, effectively taxing all income near the top marginal rate once you cross certain thresholds. This means very high earners pay close to 6.99% on nearly all their income rather than benefiting from the lower rates that apply to the first dollars earned.
Are Connecticut retirement and Social Security benefits taxed? +
Connecticut has phased in exemptions for Social Security benefits and certain pension/annuity income for filers under specific income thresholds. Higher earners may still owe state tax on retirement income, so retirees should check current-year thresholds rather than assuming full exemption.
