Does Connecticut have an estate tax?

Yes. Connecticut is one of a minority of US states — roughly a dozen nationwide — that currently levy their own state estate tax. In Connecticut, the approximate exemption threshold is $13,990,000, meaning estates valued below that amount generally owe no state estate tax, while the portion above it can be taxed at rates that approach 12% at the top end. These figures are approximate and subject to change, so confirm current thresholds with Connecticut's department of revenue or an estate planning attorney.

How does the federal estate tax fit in?

There is also a federal estate tax, but it only applies above a very high exemption amount (several million dollars per person, adjusted periodically), so it rarely affects most estates in Connecticut or elsewhere. Because Connecticut's state exemption is generally lower than the federal exemption, some estates end up owing Connecticut estate tax even though they owe nothing at the federal level.

How is this estimate calculated?

This calculator uses a simplified flat-rate model: Connecticut's approximate exemption threshold is subtracted from your estate value to find the taxable amount, and an approximate top marginal rate is applied to that excess. In reality, most states with an estate tax use graduated brackets, so actual tax owed is typically somewhat lower than this simplified flat-rate estimate suggests. This is a rough educational estimate only, not legal or tax advice — consult an estate planning attorney or tax professional for guidance specific to your situation.

Because the federal exemption is so high, it rarely affects most estates, regardless of whether Connecticut also has its own state estate tax.
