Understanding the Connecticut Estate Tax

Connecticut matches the federal exemption but has a top rate of 12%.

While the federal exemption sits at millions of dollars, Connecticut's lower threshold of $13,990,000 catches many families off guard. This is especially true when factoring in real estate values, retirement accounts, and life insurance death benefits.

If you are a resident of Connecticut, or own property here, it is highly recommended to consult an estate planning attorney to minimize your state tax burden.
