Federal, State, and Local Tax Withholding
These taxes are taken from your paycheck to fund government operations. Federal taxes include income tax, while state and local taxes vary depending on where you live in Connecticut. These withholdings are based on your earnings and the details you provide on your W-4 form.
FICA & State Insurance Taxes
FICA taxes cover Social Security and Medicare, which support retirement, disability, and healthcare benefits. Connecticut also has state-specific insurance taxes, like unemployment insurance, which helps those temporarily out of work.
Pre-Tax Deductions
These are taken from your gross pay before taxes, lowering your taxable income. They include contributions to retirement plans like 401(k) (employee contribution limit raised to $24,500 in 2026), health insurance premiums, and other benefits like flexible spending accounts (FSAs) and health savings accounts (HSAs).

Federal Tax Context for 2026
For 2026, the federal standard deduction has increased to $16,100 for single filers and married individuals filing separately, $32,200 for married couples filing jointly, and $24,150 for heads of household. These increases were enacted under the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025.
The federal SALT (State and Local Tax) deduction cap remains at $10,000, which continues to limit the benefit of deducting Connecticut state income taxes for higher earners who itemize on their federal return. For taxpayers taking the standard deduction, no deduction of Connecticut’s state income taxes is available. This means Connecticut’s tax burden can feel heavier for residents in higher income brackets who are subject to the state’s top marginal rates and cannot fully offset these against their federal taxes.
Connecticut does not impose local income taxes, so residents are not subject to any additional municipal income tax withholding.
Social Security & Connecticut Retirement Income (2026)
Connecticut technically taxes Social Security benefits, but many residents will not owe state tax on them. For 2026:
- Single filers and married filing separately with AGI below $75,000 pay no Connecticut state tax on Social Security benefits.
- Married filing jointly and head of household filers with AGI below $100,000 pay no Connecticut state tax on Social Security benefits.
- For taxpayers above these thresholds, no more than 25% of Social Security benefits are subject to Connecticut income tax.
Connecticut also fully exempts pension and annuity income from state income tax for taxpayers with federal AGI below $75,000 (single) or $100,000 (joint filers). This exemption phases out and is eliminated for those with AGI above $100,000 (single) or $150,000 (joint filers).
Wrapping up
Connecticut sits on the higher end of state income taxes, with rates ranging from 2% up to 6.99% across seven brackets. The good news is that 2024 brought the largest income tax cut in state history, and those lower bottom rates are still in effect. There are no local income taxes, keeping things simpler. One thing worth noting for retirees: Social Security and pension income get favorable treatment for moderate earners, with exemptions kicking in below certain income thresholds.

Frequently Asked Questions
The Connecticut Paycheck Calculator does not account for local taxes because Connecticut does not have local income taxes.

The Keka Connecticut Paycheck Calculator is updated for the latest tax laws, including the recent changes in tax brackets.
Connecticut’s state income tax is separate from federal taxes and cannot be deducted directly on your federal tax return. However, if you itemize deductions on your federal return, you can deduct state income taxes paid, including Connecticut’s income tax, along with other state and local taxes (SALT), up to a maximum of $10,000. This federal SALT deduction limit, introduced in 2018 under the Tax Cuts and Jobs Act, significantly reduces the benefit of deducting state taxes for high earners in states like Connecticut, which has higher tax rates and cost of living compared to many other states.
For taxpayers who take the standard deduction on their federal return, there is no option to deduct Connecticut’s state income taxes. In 2024, the federal standard deduction is $13,850 for single filers and $27,700 for married couples filing jointly, which may be more advantageous for some filers than itemizing deductions. Therefore, Connecticut’s tax burden can feel heavier for residents who cannot fully offset it against their federal taxes, particularly those in higher income brackets who are subject to Connecticut’s higher marginal tax rates and are limited by the federal SALT cap.
