Tax brackets and tax rates are ever-changing as the cost of living increases over time. Connecticut is no exception to the rule, as its tax brackets were previously updated back in 2016. These rates are no constants though, as they are bound to inflate and are modified on a yearly basis to, as mentioned above, reflect the modifications that the cost of living is witnessing over time.
Understanding Connecticut Tax Bracket
In Connecticut, taxation is governed by seven marginal tax brackets, for which the marginal rates include 3%, 5%, 5.5%, 6%, 6.5%, 6.9%, and 6.99%. Each of these marginal rates is only applicable to earnings within the corresponding tax bracket.
Furthermore, tax brackets depend on the filing type, which means that married couples, for example, who file their income tax return jointly, will generally have broader tax brackets compared to those filing their tax returns individually.
Understanding tax brackets may seem tricky, but it’s quite simple: you need to pay every Connecticut marginal tax rate starting from the lowest bracket to the highest tax bracket in which your last buck was earned. You don’t have one “tax bracket,” you have as many as your earnings go. Although for comparison sake, your Connecticut tax bracket is defined as the tax bracket in which you earned your last dollar in any tax period.
Understanding Connecticut Bracketed Income
Simply put, bracketed income tax is a flat amount that you have to pay for all your earnings to the highest bracket, along with a marginal percentage of any earnings that exceed the highest bracket. All of that is broken down in the chart below:

Connecticut Tax Deductions
Another essential feature of the Connecticut income tax that you need to understand is deductions, mainly the Connecticut Standard Deduction, the Connecticut Personal Exemption, and the Connecticut Dependent Deduction. These deductions are the most commonly encountered by taxpayers in this state, and their values for the tax year 2016 are the following:
|Standard Deduction (S)||Standard Deduction (M)||Personal Exemption||Dependent Exemption|
* Note: Connecticut is different from other states in that it treats personal exemptions state tax exemptions as tax credits – which means that instead of deducting an amount from taxable income, the exemptions reduce your actual tax liability after it has been calculated.
Breakdown of Connecticut Tax Deductions
Connecticut Standard Deduction: This is the default deduction available to every taxpayer should they fail to file an itemized deduction. The values of this deduction are:
- $0 of tax-free income per year for single taxpayers.
- $0 of tax-free income per year for taxpayers filing jointly.
Connecticut Personal Exemption: This deduction is supported by the Connecticut income tax, and it is available for every taxpayer responsible for their own living expenses.
Connecticut Dependent Deduction: In addition to the Connecticut Personal Exemption, for each qualifying dependent under your wing, such as a child or a family member, for whom you support the living expenses, you can get an additional dependent exemption. These deductions aren’t specific to Connecticut, as the Federal Income Tax also has a standard deduction, personal exemptions, and dependant deductions, which are applicable in all states nationwide. Keep in mind that their amounts and rules may differ from those of Connecticut.
