Understanding Connecticut State Taxes

Connecticut, often referred to as the “Constitution State,” has a rich history and a unique tax system. The state’s tax structure plays a significant role in its economy and is designed to support various public services and initiatives. Let’s explore the key aspects of Connecticut state taxes.
Tax Rates and Brackets
Connecticut employs a progressive tax system, meaning that the tax rate increases as your income rises. As of the 2023 tax year, the state has six tax brackets, ranging from 3.05% to 6.99%. These brackets are adjusted annually to account for inflation and changing economic conditions.
For instance, consider the following income thresholds for the 2023 tax year:
| Tax Rate | Income Thresholds |
|---|---|
| 3.05% | Up to 10,000</td> </tr> <tr> <td>4.00%</td> <td>10,001 - 50,000</td> </tr> <tr> <td>5.00%</td> <td>50,001 - 100,000</td> </tr> <tr> <td>5.50%</td> <td>100,001 - 200,000</td> </tr> <tr> <td>6.70%</td> <td>200,001 - 250,000</td> </tr> <tr> <td>6.99%</td> <td>Over 250,000 |
