Least Tax-Friendly

The Constitution State is an expensive place to live. Connecticut's property taxes are the third-highest in the U.S., so the $10,000 cap on the federal tax deduction for state and local taxes stings a bit more here. The state-wide average property tax for a $300,000 home is $6,417 per year. However, residents in high-income areas such as Fairfield County typically pay more than $10,000 in property taxes each year, so their federal tax deductions for state and local taxes have been curtailed.

Starting in 2021, most Connecticut employers also began collecting a 0.5% payroll tax to fund the state's paid family and medical leave program.

Annual Car Taxes and Fees

An annual vehicle property tax is imposed. The rates are set by individual municipalities. Motor vehicle assessments are based on 70% of the average retail value as determined by the local assessor.

Estate and Inheritance Taxes

Connecticut has an estate tax with a $7.1 million exclusion ($9.1 million in 2022). The tax due is limited to $15 million.

Connecticut is the only state with a gift tax on assets you give away while you're alive. If you made taxable gifts during the year, state law requires that you file a Connecticut estate and gift tax return to identify such gifts. However, taxes are due in 2021 only when the aggregate value of gifts made since 2005 exceeds $7.1 million ($9.1 million in 2022).

Estate and gift tax rates for 2021 range from 10% to 12%.
