Although your life insurance policy may pass to your heirs income tax-free, it can affect your estate tax. If you are the owner of the insurance policy, it will become a part of your taxable estate when you die. You should make sure your life insurance policy won't have an impact on your estate's tax liability. If your spouse is the beneficiary of your policy, then there is nothing to worry about. Spouses can transfer assets to each other tax-free. But if the beneficiary is anyone else (including your children), the policy will be a part of your estate for tax purposes.
