Understanding your paycheck deductions and estimating your net income can be challenging, especially with various federal and state tax brackets, Social Security, Medicare contributions, and optional withholdings. If you live or work in Connecticut, it’s crucial to estimate how much tax you owe and what you take home after deductions. This helps you budget smarter, plan for taxes, and avoid surprises at tax time.

Our Connecticut Income Tax Calculator is a free, easy-to-use tool that breaks down your income and withholdings clearly. It takes your gross income, filing status, pay frequency, dependents, pre-tax deductions like 401(k) or HSA contributions, and any additional withholding you might want to add — then calculates your federal taxes, Connecticut state taxes, Social Security, Medicare, and your final take-home pay per pay period.

Example: Calculating Income for a Biweekly Paid Single Filer

Let’s say Sarah is a single filer in Connecticut making $80,000 annually. She contributes $5,000 per year to her 401(k) and wants to withhold an additional $20 per paycheck. She’s paid biweekly (26 pay periods per year).

Gross Income: $80,000
Pre-Tax Deductions: $5,000 (401k)
Filing Status: Single
Pay Frequency: Biweekly
Additional Withholding: $20 per pay period

The calculator will:

Subtract pre-tax deductions from gross income to calculate taxable income.
Apply the federal tax brackets for single filers after the standard deduction ($13,850 in 2023).
Calculate Connecticut state tax based on progressive brackets.
Apply Social Security tax on wages up to $160,200.
Calculate Medicare tax plus an additional surtax if Sarah earns above $200,000 (not applicable here).
Add additional withholding of $20 per paycheck.
Show Sarah’s net pay each pay period after taxes and deductions.

This helps Sarah budget her monthly expenses confidently and make any withholding adjustments if needed.
