Connecticut Paycheck Tax Calculator: How Connecticut Withholding Works
A Connecticut paycheck calculator has to follow the
DRS formula, not a flat percentage. Connecticut annualizes your wages,
subtracts an exemption that depends on your CT-W4 code, applies rates
from 2% to 6.99%, adds back the benefit of the 2% bracket for higher
earners, adds tax recapture above set income levels and then applies
a personal tax credit. That's why Connecticut tax on a $60,000 salary
is about 3.9% of pay, not 5.5%. On your pay stub it usually shows up
as SIT or state withholding.
Form CT-W4
Every Connecticut employee should give their employer a Form CT-W4.
The code you choose (A, B, C, D, E or F) sets your exemption and
credit, Line 2 adds a dollar amount to each paycheck and Line 3
lowers it. DRS asks you to file a new CT-W4 at least once a year, and
within ten days of a change such as marriage or a large bonus. If you
don't file one, your employer must withhold at 6.99% with no
exemption.
CT Paid Leave: 0.5% Up to $184,500
CT Paid Leave funds paid family and medical leave benefits for
Connecticut workers. Employees pay 0.5% of wages through payroll, and
contributions stop once your wages for the year reach the Social
Security wage base of $184,500. Pre-tax 401(k) contributions don't
reduce it. Employers don't pay a matching share.
Federal Withholding for Connecticut Paychecks
Federal withholding uses your Form W-4 and the 2026 IRS Publication
15-T tables. The calculator supports filing status, Step 2(c), Step 3
credits and Step 4(a), 4(b) and 4(c). If you claim the new overtime
or tips deductions, our
W-4 Step 4(b) worksheet guide
shows how to enter them, and our
2026 federal tax withholding guide
covers the rest.
Living in Connecticut, Working in New York
Many Connecticut residents commute to New York. New York taxes wages
earned there, so your employer withholds New York tax, and
Connecticut gives you a credit for it on your Connecticut return.
There's no reciprocal agreement between the states. Nonresidents who
work partly in Connecticut can file Form CT-W4NA so the employer
withholds only on Connecticut wages. Compare paychecks with our
New York paycheck calculator.
No Local Income Tax
No Connecticut city or town taxes wages. Hartford, New Haven,
Stamford, Bridgeport and every other town add nothing to your
paycheck deductions.
Employer Payroll Costs in Connecticut
Some Connecticut payroll taxes never show up as a deduction.
Employers pay state unemployment insurance
on the first $27,000 of each employee's wages in 2026 (1.9% for new
employers), plus their share of Social Security and Medicare and
federal unemployment tax. When year-end comes, our
W-2 form generator
can use the same wage and withholding totals.
Why Your Actual Connecticut Paycheck May Differ
This calculator is a close estimate, not your employer's payroll
run. Your CT-W4 code on file, table-method rounding, benefit
elections, year-to-date wages and a 27th biweekly payday in some
years can all move the result a little. Bonuses can be withheld
differently from regular pay; see
why bonuses are taxed so high.
