If you expect your estate to have a significant estate tax liability at your death, be sure to include a well-thought-out tax apportionment clause in your will or revocable trust. An apportionment clause specifies how the estate tax burden will be allocated among your beneficiaries. Omitting this clause, or failing to word it carefully, may result in unintended consequences.
There are many ways to apportion estate taxes. One option is to have all of the taxes paid out of assets passing through your will. Beneficiaries receiving assets outside your will — such as IRAs, retirement plans or life insurance proceeds — won’t bear any of the tax burden.
