Connecticut Biweekly Paycheck Calculator 2026

Here is exactly what your biweekly paycheck looks like in Connecticut at common annual salary levels in 2026. Calculated for a single filer, standard W-4, biweekly pay frequency, no pre-tax deductions.

Single filer · standard W-4 · biweekly pay (26 periods/yr) · no pre-tax deductions · 2026 IRS withholding tables · Connecticut published 2026 withholding method. Actual paychecks vary based on filing status, allowances, and deductions.

Connecticut withholds state income tax from every paycheck. Your biweekly paycheck includes these deductions:

• Federal income tax (2026 IRS withholding tables)
• Connecticut state income tax (withheld each pay period)
• Social Security tax — 6.2% on wages up to $184,500
• Medicare tax — 1.45% on all wages
• Employee benefit deductions

A biweekly pay schedule means you receive a paycheck every two weeks — 26 paychecks per year. To find your gross biweekly pay, divide your annual salary by 26:

Two months per year you will receive three biweekly paychecks instead of two. This is sometimes called a "three-paycheck month." Because benefit deductions are often fixed per paycheck, the extra check can feel larger than usual.

Your net biweekly paycheck in Connecticut depends on your annual salary, W-4 filing status, Connecticut state withholding elections, retirement contributions, health insurance deductions, and any additional withholding.

Connecticut assigns every employee a withholding code from A to F on Form CT-W4, and the code drives the entire calculation. When no valid form is on file, Connecticut's default is not a middle-of-the-road table — it is Code F, which withholds at the state's top marginal rate of 6.99% on all wages with no exemptions.

On a biweekly schedule this is punishing and silent: 26 checks withheld at a rate meant for the highest earners, with the excess recoverable only at filing. It is the single most common reason a Connecticut deposit comes in far below an estimate. Check which code payroll has before you look anywhere else.

Connecticut withholds a Paid Leave contribution of 0.5% of wages up to the Social Security taxable wage base, $184,500 in the calculator above. Tying the ceiling to the federal base means the Connecticut premium and the Social Security deduction stop on the same paycheck.

For a biweekly earner above the base, one period late in the year drops both lines at once and the deposit jumps noticeably. It is not a payroll error and it does not repeat — the following January both lines return.

Connecticut maintains no reciprocal agreements. A Connecticut resident working in New York has New York tax withheld from every biweekly check, and New York's convenience-of-the-employer rule can source remote days to New York as well, even when you are working from a Connecticut desk.

Connecticut grants a credit for tax paid to another state, but the credit arrives at filing while the withholding happens 26 times during the year. Connecticut has also adopted its own retaliatory convenience provision, which can apply the same logic in the other direction for residents of states that use the rule.
