Connecticut Paycheck Calculator

Connecticut withholding is unusually intricate: your employer applies one of five withholding codes (A–D, F) from Form CT-W4 to look up a personal exemption, a 2%–6.99% initial tax, a benefit-recapture add-back for higher earners, and a credit percentage that phases out as income rises. It's Connecticut's way of approximating its graduated income tax paycheck-by-paycheck. Connecticut has no local income taxes.

Connecticut withholding follows TPG-211, 2026 Withholding Calculation Rules (inside IP 2026(1), Circular CT): annualize wages, subtract a Table A personal exemption keyed to the employee's Form CT-W4 withholding code (A/B/C/D/F), compute an initial tax from Table B, add a Table C 2%-phase-out add-back and a Table D tax-recapture amount (both looked up by annualized SALARY, not taxable income), then multiply the sum by (1.00 minus a Table E personal-credit decimal, also looked up by annualized salary). Code D uses a $0 exemption and 0.00 credit (elects the highest withholding level); Code E means no withholding is necessary ($0). An employee who does not return a completed CT-W4 is withheld at a flat 6.99% with no exemption. Connecticut has no local income taxes.
No Form CT-W4 on file: withheld at the flat 6.99% rate with no exemption, per Circular CT.

Connecticut paycheck FAQs

What is a Connecticut withholding code?

Codes A, B, C, D, E, or F, chosen on Form CT-W4 based on filing status and combined household income. Each points to its own exemption and credit schedule, so two employees earning the same salary can see very different withholding.

What happens if I don't file a CT-W4?

Your employer must withhold at the flat top rate of 6.99% with no exemption at all — the maximum possible Connecticut withholding.

Why would my withholding jump sharply at a higher salary?

Connecticut claws back the benefit of its lower brackets for higher earners through a 'tax recapture' add-back once income passes roughly $100,500–$210,000, depending on your withholding code.
