Navigating your paycheck can sometimes feel like deciphering a complex code. This Connecticut Paycheck Calculator is designed to help you understand how your gross earnings are transformed into your net take-home pay, considering federal and state taxes, as well as common deductions specific to Connecticut residents.
What is Gross Pay?
Your Gross Pay is the total amount of money you earn before any taxes or deductions are taken out. This is typically calculated based on your hourly wage multiplied by the hours worked, or your annual salary divided by your pay periods (e.g., 26 for bi-weekly, 12 for monthly).
Federal Income Tax Withholding
Federal income tax is a mandatory deduction that supports federal government programs. The amount withheld from your paycheck depends on several factors, including your gross pay, your filing status (Single, Married Filing Jointly), and the number of dependents or other adjustments you claim on your W-4 form. The calculator uses a simplified progressive tax bracket system and standard deductions for estimation.
FICA Taxes: Social Security and Medicare
FICA stands for the Federal Insurance Contributions Act, which funds Social Security and Medicare. These are mandatory federal taxes:
Social Security: This tax is 6.2% of your gross wages, up to an annual wage limit (e.g., $168,600 for 2024). This fund provides benefits for retirees, the disabled, and survivors.
Medicare: This tax is 1.45% of all your gross wages, with no income limit. It funds healthcare services for the elderly and disabled.
Your employer also pays an equal amount for both Social Security and Medicare taxes on your behalf.
Connecticut State Income Tax
Connecticut imposes its own state income tax, which is also a progressive tax, meaning higher earners pay a higher percentage. The amount withheld depends on your gross pay, your CT filing status (Single, Married Filing Jointly), and any personal exemptions you may qualify for. Connecticut's tax system includes several tax brackets and a personal exemption that phases out at higher income levels. Our calculator uses a simplified model for these calculations.
Deductions
Deductions are amounts subtracted from your gross pay. They can be categorized as:
Pre-Tax Deductions: These are taken out of your pay before taxes are calculated, effectively reducing your taxable income. Common examples include contributions to a 401(k) or 403(b) retirement plan, health insurance premiums, and Flexible Spending Account (FSA) contributions.
Post-Tax Deductions: These are taken out of your pay after taxes have been calculated. Examples include Roth 401(k) contributions, union dues, charitable contributions, or garnishments.
How to Use the Calculator
Gross Pay per Pay Period: Enter your total earnings for one pay period before any deductions.
Pay Frequency: Select how often you get paid (e.g., weekly, bi-weekly).
