How Connecticut taxes your paycheck in 2026
Connecticut uses graduated brackets running from 2% up to 6.99%. On top of that, every Connecticut worker pays federal income tax plus 6.2% Social Security (on the first $184,500 of 2026 wages) and 1.45% Medicare with no cap. This calculator applies all of it at once, so the take-home figure is the real one.

Connecticut payroll deductions beyond income tax
Connecticut employees also pay these premiums directly from each paycheck — separate from income tax, and often missed by federal-only calculators.

|---|---|---|
| CT Paid Leave | 0.5% | First $184,500 of wages |
How Connecticut compares with neighbouring states
State income tax owed by a single filer on a $75,000 salary — Connecticut against the states around it:
| State | Tax on $75,000 | Effective rate |
|---|---|---|
| Rhode Island | $2,196 | 2.93% |
| Connecticut (this state) | $2,550 | 3.40% |
| New Jersey | $2,598 | 3.46% |
| New York | $3,453 | 4.60% |
| Massachusetts | $3,530 | 4.71% |
Connecticut ranks second-lowest of these 5 at that salary, costing about $354 a year more than Rhode Island. Where you physically work usually decides which state withholds, so a short commute across a border can change your take-home meaningfully.
Why your effective Connecticut rate isn't 6.99%
On a $75,000 salary the headline rate is 6.99%, but the real bite is about 3.40%. Two things cause the gap. First, the brackets are marginal — only income inside each band is taxed at that band's rate. Second, Connecticut shelters the first $15,000 of income before any tax applies.
Worth noting: Connecticut's $15,000 of shelter is well below the federal standard deduction of $16,100, so you pay Connecticut tax on roughly $1,100 more income than you pay federal tax on — about $77 a year in extra state tax at the top rate.
