About This Calculator
Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions.
How Income Taxes Are Calculated
-
First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
-
Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer.
-
Based on your filing status, your taxable income is then applied to the tax brackets to calculate your federal income taxes owed for the year.
-
Your location will determine whether you owe local and / or state taxes.
When Do We Update? - We check for any updates to the latest tax rates and regulations annually.
Customer Service - If you would like to leave any feedback, feel free to email info@smartasset.com.
Assumptions
Deductions
- "Other Pre-Tax Deductions" are not used to calculate state taxable income.
Credits
- The only federal credit automatically calculated is the Savers Credit, depending on your eligibility.
- We do not apply any refundable credits, like the Child Tax Credit or Earned Income Tax Credit (EITC).
- We do not apply state credits in our calculations.
Itemized Deductions
- If itemizing at the federal level, you may need to itemize at the state level too. Some states don't allow itemized deductions, which is accounted for in our calculations.
- When calculating the SALT deduction for itemized deductions, we use state and local taxes, and we assume your MAGI.
- We assume that there is no cap to itemized deductions, if a state allows them.
- We do not categorize itemized deductions (such as medical expenses or mortgage interest), which could be subject to specific caps per state.
Local Tax
- Depending on the state, we calculate local taxes at the city level or county level. We do not include local taxes on school districts, metro areas or combine county and city taxes.
- With the exception of NYC, Yonkers, and Portland/Multnomah County, we assume local taxes are a flat tax on either state taxable income or gross income.

Connecticut State Tax Quick Facts
- Income tax: 2% – 6.99%
- Sales tax: 6.35%
- Property tax: 1.66% effective rate
- Gas tax: 25 cents per gallon of regular gasoline
The state of Connecticut generates most of its revenue through an individual income tax and a statewide sales tax. Income tax rates range from 2.00% to 6.99%; that top rate ranks above the U.S. average. The sales tax rate of 6.35% is also high relative to other statewide rates, but because there are no local sales taxes in Connecticut, that is the maximum rate levied anywhere in the state. That makes Connecticut among the more tax-friendly states for shoppers.
Since there are no local income or sales taxes in Connecticut, local governments must collect most of their revenue through property taxes. That is reflected in the state’s high effective property tax rates. In fact, the typical Connecticut homeowner pays $6,484 annually in property taxes.

Connecticut Income Taxes
Connecticut’s personal income tax is a relatively recent development. More specifically, up until 1991, only capital gains, interest and dividends were taxed. For tax year 2025, those income sources, as well as wages and salaries, are taxed at marginal rates between 2% and 6.99%. The rates paid by a particular taxpayer are determined by tax brackets, as shown in the table below.
Income Tax Brackets
| Rate | Single Filers | Married, Filing Jointly | Married, Filing Separately | Head of Household |
|---|---|---|---|---|
| 2.00% | $0 – $10,000 | $0 – $20,000 | $0 – $10,000 | $0 – $16,000 |
| 4.50% | $10,000 – $50,000 | $20,000 – $100,000 | $10,000 – $50,000 | $16,000 – $80,000 |
| 5.50% | $50,000 – $100,000 | $100,000 – $200,000 | $50,000 – $100,000 | $80,000 – $160,000 |
| 6.00% | $100,000 – $200,000 | $200,000 – $400,000 | $100,000 – $200,000 | $160,000 – $320,000 |
| 6.50% | $200,000 – $250,000 | $400,000 – $500,000 | $200,000 – $250,000 | $320,000 – $400,000 |
| 6.90% | $250,000 – $500,000 | $500,000 – $1,000,000 | $250,000 – $500,000 | $400,000 – $800,000 |
| 6.99% | $500,000+ | $1,000,000+ | $500,000+ | $800,000+ |
For tax year 2025, the tax brackets remain the same as for tax year 2024.
These tax rates are based on Connecticut taxable income, which is derived from your federal adjusted gross income (AGI). To arrive at Connecticut taxable income, generally all that needs to be done is to subtract the Connecticut personal exemption from federal AGI. Consider looking into tax preparation software like TaxAct and TaxSlayer to help file your taxes.
The personal exemption in Connecticut can be as much as $24,000, depending on filing status and income. In general, exemptions decline as total annual wages or salary grows. The table below shows the personal exemptions based on filing status and total annual wages for taxpayers in Connecticut. Note that this is not based on taxable income (i.e. income after deductions and exemptions), but rather total wages. For joint filers, these apply to each spouse’s income separately, and can be claimed for both spouses, if both are working.

Connecticut Tax Credits
Connecticut is different from other states in that it treats personal exemptions for state taxes as credits. That means instead of deducting an amount from taxable income, Connecticut residents reduce their tax liability after it has been calculated.
In general, Connecticut uses tax credits instead of deductions. Among these are the Connecticut Earned Income Tax Credit (CT EITC), which mirrors the federal credit, and the Property Tax Credit, up to $300 for eligible Connecticut homeowners with property tax liability.
Connecticut Sales Tax
Connecticut has a single, statewide sales tax, and no local sales taxes. Regardless of where you are in the state, you will pay 6.35% on most goods and some services. Additionally, the sales tax rate jumps to 7.75% for the sale of more than $50,000 of most cars.
Connecticut does not tax most types of food typically purchased in a grocery store. Items like fruit, meat, pasta, rice, salsa and bread are nontaxable. However, many types of food in single-serving packages, like small bags of chips or cookies, are taxable, as are candy and soda. Prepared food of any kind is also taxable.
Connecticut Property Tax
Homeowners in Connecticut pay a median real estate tax of $6,573. This is an effective property taxes rate of 1.66%, which is the third-highest following Illinois and New Jersey. The median home in the Nutmeg State is $396,900.

Connecticut Estate Tax
Like many states in the Northeast, Connecticut has its own tax on estates. The state’s lifetime exemption limit mirrors the federal limit. For tax year 2025, the first $13.99 million of an estate is exempt from estate tax.
However, estates that exceed these limits will pay a 12% tax on their taxable value above the exemption. So, if a person dies in 2025 with an estate worth $15 million, the Connecticut estate tax will apply to $1.01 million of its value.
Connecticut Gas Tax
The state gas tax on regular fuel in Connecticut is 25 cents per gallon.
Connecticut Capital Gains Tax
Capital gains are taxed as regular income in Connecticut, which means they face a top rate of 7%.
Connecticut Cigarette Tax
Connecticut has one of the highest cigarette taxes in the nation at $4.35 per pack.
Connecticut Alcohol Tax
The state reduced its alcohol tax rates in 2024. The total tax on distilled spirits is $5.94 per gallon, and $0.19 per gallon for beer.
