Understanding Your Connecticut Payroll
This calculator provides an estimate of an employee's net pay (take-home pay) based on gross earnings, Connecticut's specific tax regulations, federal taxes, and standard payroll deductions.
Key Components of Payroll Calculation:
Gross Pay: The total amount of money earned before any deductions are taken out. This is based on your hourly rate and hours worked, or your salary, for the specified pay period.
Federal Income Tax Withholding: Calculated based on the IRS Form W-4 information (filing status, number of allowances) and IRS tax tables. The exact method can vary slightly between payroll systems.
State Income Tax Withholding (Connecticut): Connecticut has a progressive income tax system. Withholding is determined by the employee's CT W-4 (filing status, number of allowances) and tax tables provided by the state.
Social Security Tax: A federal tax of 6.2% on earnings up to an annual wage base limit.
Medicare Tax: A federal tax of 1.45% on all earnings, with no wage base limit.
Connecticut Paid Leave (CT Paid Leave / SUI): This deduction covers the state's Paid Family and Medical Leave program. The rate is set annually by the state.
Net Pay: The final amount an employee receives after all deductions and withholdings have been subtracted from the gross pay.
Connecticut Specifics:
Connecticut's tax system involves both state income tax and the CT Paid Leave program. This calculator aims to incorporate these elements accurately for estimation purposes.
State Income Tax Brackets: CT uses a graduated tax rate. The higher your income, the higher the percentage of tax you pay on the portion of income within that bracket.
CT Paid Leave Rate: The rate for the CT Paid Leave program is subject to change and is updated periodically by the state.
How to Use the Calculator:
Enter your Gross Pay for the pay period.
Select your Pay Frequency (e.g., Weekly, Bi-Weekly, Monthly).
Provide your Federal Filing Status and the number of Federal Allowances you claim on your W-4.
Select your CT Filing Status and the number of CT Allowances you claim.
Enter the current CT Paid Leave (SUI) Rate as a percentage. The default is set to a common rate, but verify with your employer or the CT government for the current year.
Enter the Social Security Rate and Medicare Rate. These are standard federal rates.
