Connecticut paycheck calculator
Connecticut's income tax looks simple at first, with seven brackets from 2% to 6.99%, but its personal exemption, low-bracket benefit and personal tax credit all phase out as income rises. Employers capture all of that with a five-table calculation keyed to the letter code you choose on Form CT-W4. Nearly every Connecticut worker also pays the CT Paid Leave contribution.

How Connecticut withholds income tax
Connecticut has no percentage method. Employers either use the Department of Revenue Services wage-bracket tables or the calculation rules in TPG-211: annualize the paycheck, subtract a personal exemption that shrinks as pay rises, compute tax on the brackets, add back the phase-out of the 2% bracket and a recapture amount at higher incomes, then reduce the result by a personal tax credit that also shrinks with income.
Everything hinges on the withholding code on Form CT-W4. Single filers usually use Code F, heads of household Code B, and married couples filing jointly Code C if one spouse works or Code A or D if both do. Code D withholds the most and is meant for people with significant other income. This calculator picks the code from your filing status.
Connecticut starts from federal withholding wages, so traditional 401(k) contributions, pre-tax health premiums and cafeteria-plan HSA contributions all reduce the wages Connecticut withholds on.
If you skip Form CT-W4
An employee who never hands in a completed CT-W4 is withheld at a flat 6.99% of wages with no exemption. That is far more than most people owe, so filing the form matters. You should also file a new CT-W4 within ten days if your filing status changes or you get a large bonus.
CT Paid Leave contributions
Connecticut's paid family and medical leave program is funded entirely by employees through a payroll deduction. It applies to the same wages used for Social Security and stops once you reach the Social Security wage base for the year.
Each employer deducts separately, so if you change jobs mid-year you may contribute again with the new employer until you reach the cap there.
Bonuses and local taxes
Connecticut has no flat bonus rate. When a bonus is paid on its own, the employer adds it to your last regular paycheck, figures the tax on the total and subtracts what it already withheld, so a large bonus can be withheld at your top marginal rate.
Connecticut towns and cities do not tax wages, so there is no local income tax on top of the state tax.

Questions people ask
What withholding code should I use on Form CT-W4?
Single filers earning over $15,000 use Code F and heads of household over $19,000 use Code B. Married couples filing jointly use Code C if one spouse is not employed, Code A if both work and combined income is $100,500 or less, and Code D above that. Code E means no withholding for very low incomes.
How much is the CT Paid Leave deduction in 2026?
It is 0.5% of your wages, up to the 2026 Social Security wage base of $184,500, for a maximum of $922.50 with one employer. Benefits excluded from Social Security wages, such as pre-tax health premiums, are not included.
What happens if I don't fill out a CT-W4?
Your employer must withhold Connecticut tax at a flat 6.99% of wages with no exemption, which is usually much more than you will owe.
How are bonuses taxed in Connecticut?
There is no flat supplemental rate. If the bonus is paid separately, your employer adds it to your regular wages for the period, figures the tax on the combined amount and withholds the difference from the bonus.
Does Connecticut tax 401(k) contributions?
No. Connecticut follows federal withholding rules, so traditional 401(k) deferrals, pre-tax health premiums and cafeteria-plan HSA contributions are not subject to Connecticut withholding.
Do Connecticut cities have an income tax?
No. Connecticut has no city or town income taxes, so where you live within the state does not change your withholding.
