The responsibility for paying estate tax on Life Insurance depends on the ownership of the policy and the beneficiary designation. In general, if the policy is owned by the deceased individual, the value of the policy is included in their estate for tax purposes. In this case, the estate would be responsible for paying any applicable estate taxes. However, if the policy is owned by someone else, such as a trust or another individual, the proceeds may be excluded from the estate and not subject to estate tax. It's important to note that estate tax laws can vary by jurisdiction, so it's always a good idea to consult with a tax professional or estate planning attorney for specific guidance.
