Connecticut Estate Tax Exemption

Connecticut is one of 12 states, plus the District of Columbia, that imposes an estate tax. While the vast majority of families aren’t affected by the federal estate tax (because of how high the exemption is), Connecticut’s estate tax affects a greater proportion of estates. For estates of people who died in 2021, the tax won’t apply if the estate is less than $7.1 million. That goes up to $9.1 million in 2022 and $11.4 million in 2023.  The estate tax is due within six months of the estate owner’s death, though a six-month extension may be requested.

The estate tax rate is progressive and payable on the value of the entire taxable estate. The tax rate ranges from 10.8% to 12% for 2021 and from 11.6% to 12% for 2022. In 2023, there will be a flat rate of 12%.

What Is the Estate Tax?

The estate tax is a tax applied to an estate after a person dies but before the person’s money gets passed on to heirs. It is sometimes called the “death tax.” Only estates that reach a certain threshold are subject to the estate tax.

The estate tax is not the same as the inheritance tax, which is levied after the estate is dispersed to a person’s beneficiaries. While the estate tax is taken out of the estate, the beneficiaries are responsible for paying the inheritance tax.

Connecticut Inheritance Tax

There is no inheritance tax in Connecticut. However, another state’s inheritance tax may apply to you if your grantor lived in a state that has an inheritance tax. In Kentucky, for instance, the inheritance tax applies to all in-state property, even if the inheritor lives in another state. If someone who lives out-of-state leaves you something, make sure to check the local laws in your grantor’s state to see if you owe inheritance tax.

Connecticut Gift Tax

Connecticut is the only state in the union that levies its own gift tax. The lifetime exemption is equal to the estate tax exemption. There is also a yearly exemption of $15,000 per person per year.

The federal gift tax has the same yearly exemption, which is $16,000 in 2022. The federal lifetime exemption is $12.06 million as of 2022.

Connecticut Estate Tax for Married Couples

Connecticut does not have portability for spouses. When the second spouse of a married couple dies, only one exemption applies.

Federal Estate Tax

There is a federal estate tax that may apply on top of the Connecticut estate tax, but it has a higher exemption level of $12.06 million in 2022. This exemption is portable between spouses. This means a couple can protect up to $24.12 million with proper legal steps.

The top tax rate for the federal estate tax is 40%. Using the same method described above, you can find your federal estate tax burden within the table below.

Taxable Estate* Base Taxes Paid Marginal Rate Rate Threshold**
$1 – $10,000 $0 18% $1
$10,000 – $20,000 $1,800 20% $10,000
$20,000 – $40,000 $3,800 22% $20,000
$40,000 – $60,000 $8,200 24% $40,000
$60,000 – $80,000 $13,000 26% $60,000
$80,000 – $100,000 $18,200 28% $80,000
$100,000 – $150,000 $23,800 30% $100,000
$150,000 – $250,000 $38,800 32% $150,000
$250,000 – $500,000 $70,800 34% $250,000

$750,000 – $1 million $248,300 39% $750,000
Over $1 million $345,800 40% $1 million

*The taxable estate is the total above the exemption of $12.06 million.

Overall Connecticut Tax Picture

Connecticut estate tax

Connecticut is not tax-friendly for retirees. In fact, it ranks among the least tax-friendly states in the country for those in their golden years. The state fully taxes withdrawals from retirement accounts, like IRA or 401(k) plans, as well as payments from private or public pension plans. It also taxes Social Security. However, seniors who have an adjusted gross income below $75,000 ($100,000 for joint filers) are exempt from Social Security taxes. Connecticut’s income tax rate ranges from 3.00% to 6.99%.

The average property tax rate in Connecticut is 2.14%, the third highest in the country. That said, seniors age 65 and over who own and occupy a Connecticut home are eligible for a property tax circuit breaker of up to $1,250 for married couples or $1,000 for individuals.

Sales tax is 6.35% throughout Connecticut. There are no local sales taxes.
