How much tax is taken out of my paycheck in Connecticut?

Pick your letter from Form CT-W4 first. Without one, Connecticut withholds a single rate on the entire wage, and that is what the calculator shows until a letter is chosen. With one, the state's rules subtract an exemption that shrinks with pay, read the schedule the letter names, add back part of the lower brackets' benefit at higher incomes and take off a personal credit. Letter D, for a combined income above the line the form names or a large income besides wages, gets neither the exemption nor the credit. CT Paid Leave comes out alongside.

Who is exempt from CT state income tax?

On a paycheck, exemption is a letter: Form CT-W4 offers E for an employee who needs no withholding or claims the MSRRA exemption the form names, and with E nothing is withheld. Whether a person owes no Connecticut tax at all is settled on the annual return rather than by an employer, so a withholding page cannot answer that for anyone.

Does filing status matter for Connecticut withholding?

Not on the state line. Connecticut takes its schedule, exemption and credit from the CT-W4 letter, so two employees on the same pay and letter see the same figure whatever filing status they gave; the field still changes federal withholding. It is also why a married employee whose spouse works can end up on the single filer's schedule through letter A.

Can I have extra Connecticut tax withheld each paycheck?

Yes. Line 2 of Form CT-W4 names a flat amount to withhold on top of the rules every pay period, and the calculator has a field for it. Line 3 does the opposite, reducing withholding by a flat amount but never below zero, and an employee living outside Connecticut is taxed only on the work done in the state; both of those are in the generator rather than here.

Connecticut paycheck calculator

Connecticut publishes no percentage formula. It writes withholding as a set of calculation rules keyed to the letter an employee picks on Form CT-W4, and the letter settles nearly everything: whether there is an exemption, which shrinks as pay rises, the schedule that is read, two add-backs at higher incomes, and whether a personal credit removes a share of the tax.

How Connecticut withholding is worked out

Until a letter is chosen, the calculator does what Connecticut requires of an employer holding no CT-W4: one rate on the whole wage, with no exemption. Picking the letter from your form switches to the state's rules. A married employee whose spouse also works, below the combined income the form names, takes A, which reads the single filer's schedule, as D and F do; C, for a couple with one earner, reads the joint schedule, B reads the head of household one, and E withholds nothing. Filing status moves only the federal line, since the letter makes every state choice. Beside the income tax, CT Paid Leave takes a fixed share of pay up to the Social Security wage limit; employees fund it in full and cannot opt out.

These are withholding figures: what an employer takes out of one paycheck, which is not the same calculation as the one on an annual return.

Connecticut picks the schedule by the letter on its own form, not by the filing status, and each table below is headed with the letters that read it. Until a letter is given, 6.99% of the whole wage is withheld, plus any extra amount entered on the form, and no table is read. Code E withholds nothing unless an extra amount is entered. Wages are annualised first, so the figures below are annual.

IP 2026(1), Connecticut Employer's Tax Guide (Circular CT), which carries TPG-211, 2026 Withholding Calculation Rules (Rev. 12/25). Connecticut publishes no percentage method at all: an employer either follows those rules or reads the bracket tables, which stop at $1,932 a week, so the rules are what is modelled here. The five tables are transcribed from IP 2026(7), which prints the same 2026 figures with a text layer, and every band is cross-checked against Form CT-1040 TCS (Rev. 12/25). The withholding code names all five, and an employer holding no Form CT-W4 withholds 6.99% of the whole wage without allowance for exemption, which is what an unnamed code does here. The figures are checked against the state's own 2026 Connecticut Withholding Calculator for Form CT-W4, in myconneCT, which the state publishes no worked example for.

Withheld beside the income tax

CT Paid Leave — 0.5%: Connecticut's paid family and medical leave contribution. Employees fund the programme in full, the employer pays no share of it, and an employee cannot opt out. Withheld until wages for the year reach $184,500.00.
