Connecticut tax guide
Connecticut's tax system is designed as a progressive structure, ensuring that tax rates increase with higher income levels. By utilizing seven distinct brackets, the state balances revenue needs while attempting to account for varying taxpayer abilities to pay. Unlike neighboring New York, Connecticut maintains a lower top-tier tax burden, though it remains higher than the progressive rates found in Massachusetts.
Key tax highlights
Payroll
- Connecticut personal income tax rates range from 3.00% to 6.99% based on seven specific tax brackets.
- The state uses a phase-out mechanism for personal exemptions, meaning higher-income earners receive fewer tax benefits.
- Connecticut requires state income tax withholding on payroll, which is calculated based on the employee's gross pay and filing status.
Local taxes
- Unlike many states, Connecticut does not levy local or municipal income taxes on residents.
- Property taxes are the primary source of local revenue, and they vary significantly between towns and cities.
Deductions
- Connecticut provides personal exemptions that decrease as a taxpayer's Connecticut Adjusted Gross Income (AGI) increases.
- There is a credit for property taxes paid, though it is subject to strict income limitations and eligibility criteria.
- Qualified taxpayers may benefit from the Connecticut earned income tax credit, which is calculated as a percentage of the federal credit.
