About Deductions

This estimate includes standard federal withholding, FICA taxes (7.65%), and state income tax rates applicable in CONNECTICUT. Local county taxes are factored in where applicable.

Understanding Your Paycheck in CONNECTICUT

When you receive your paycheck, the amount listed as “net” or “take‑home” is what remains after several mandatory and optional deductions. In New London County, as throughout the rest of Connecticut, the primary compulsory deductions are:

• Federal Income Tax: Withheld according to the IRS tax tables and your personal W‑4 elections.
• Connecticut State Income Tax: A progressive tax that ranges from 3% to 5.5% for 2024, applied after federal taxes have been taken out.
• FICA (Social Security and Medicare): A flat 6.2% for Social Security on the first $168,600 of earnings (2024) and 1.45% for Medicare on all wages, plus an additional 0.9% Medicare surtax on wages above $200,000 for single filers.

Employers may also deduct amounts for health insurance premiums, retirement plans, and other benefit programs you elect, which further reduce your gross pay before the net amount is calculated.

Federal Tax Withholding

The amount the IRS requires your employer to withhold depends on the information you provide on the Form W‑4. The form now asks for:

• Filing status (single, married filing jointly, married filing separately, or head of household).
• Number of dependents or other adjustments that affect taxable income.
• Any extra amount you want withheld each pay period.

Federal tax operates on a progressive bracket system. For 2024 the brackets start at 10% for the first $11,600 of taxable income (single) and rise to 37% for income over $578,125. Your employer uses the IRS percentage method to calculate the exact dollar amount to withhold each pay period, based on your cumulative earnings, filing status, and W‑4 inputs.

Changing the number of allowances or adding an “extra withholding” amount can increase or decrease the federal portion taken out of each check, affecting the size of any refund or balance due when you file your tax return.

State & Local Taxes

Connecticut’s income tax is also progressive, with rates for 2024 as follows:

• 3.0% on the first $10,000 of taxable income.
• 4.7% on income between $10,001 and $50,000.
• 5.5% on income above $50,000 (the top rate).

The state tax is calculated after federal withholding and before any pre‑tax benefit contributions (e.g., 401(k), HSA). Connecticut does not impose a separate county payroll tax, so New London County residents only pay the state income tax, not any additional local income tax.

Additional state deductions can include a personal exemption ($3,200 per adult in 2024) and credits such as the Earned Income Credit (EIC) and the Connecticut Property Tax Credit, which can lower your state withholding.

Maximising Your Take-Home Pay

While you cannot eliminate mandatory taxes, strategic adjustments can boost your net pay:

• Review your W‑4 annually: If you received a large refund or owed a lot last year, adjust your allowances or add extra withholding to better align with your actual tax liability.
• Contribute to a 401(k) or 403(b): Pre‑tax contributions reduce both federal and state taxable wages, lowering current-year taxes while building retirement savings.
• Open a Health Savings Account (HSA): If you have a high‑deductible health plan, HSA contributions are tax‑free at the federal level and also exempt from Connecticut state tax.
• Utilise flexible spending accounts (FSA): Dependent care and medical FSAs lower taxable income on a pre‑tax basis, increasing take‑home pay.
• Claim eligible tax credits: The federal Child Tax Credit, American Opportunity Credit, and Connecticut’s earned income credit can reduce tax liability, effectively raising net pay.

Finally, keep an eye on any changes to federal or Connecticut tax laws each year. Small shifts in brackets, exemption amounts, or credit eligibility can have a noticeable impact on your paycheck.
