Trusts are used to control assets in a separate legal entity from the trust creator, known as a grantor. Some trusts are effective immediately upon creation, while others become effective upon the grantor’s passing. After the grantor’s passing, the trust is managed by the trustee. How this works depends on the type of trust and the instructions in the trust document, according to a recent MSN article, “What happens to a trust after the grantor dies?”
The trust enters a new phase when the grantor dies, depending on the type of trust established. Revocable living trusts typically become irrevocable trusts upon the grantor’s death. At this point, no changes can be made to the terms or beneficiaries. For irrevocable trusts, the grantor’s death triggers distribution in accordance with the trust’s instructions.
The biggest shift in the trust is the change of control from the grantor to the successor trustee. This person now begins notifying beneficiaries, gathering and valuing assets, paying any outstanding debts or taxes and distributing assets. Like an executor, the trustee has a fiduciary duty to act in the best interest of the beneficiaries.
The trustee may need to liquidate investments, transfer property titles, or establish ongoing asset management if the assets are intended to provide income to beneficiaries over time. When the grantor dies, the trust must file its own tax return and pay any estate or income taxes due.
Transferring assets held by the trust is one of the biggest tasks. The assets don’t go through probate—the reason a trust was created—so there is little delay before they can be distributed (unless the trust is designed for a longer period).
The trustee must gather all trust records, including titles, deeds, investment accounts and insurance policies. They must notify financial institutions of the grantor’s death and provide proof that they are the legal representative of the trust.
Once debts and taxes are addressed, assets are distributed. This may involve transferring property ownership or distributing cash from investment accounts. Some trusts direct the trustee to make an immediate lump-sum payment, while others have distribution requirements, such as requiring assets to be distributed upon reaching certain life milestones.
Tax obligations are triggered when the grantor dies. A revocable living trust previously using the grantor’s Social Security number becomes a separate tax entity at death. The trustee must obtain a new taxpayer number from the IRS and start filing Form 1041, the U.S. Income Tax Return for Estates and Trusts, to report income earned by the trust after the grantor’s death.
Depending on the value of the assets, federal or state estate taxes may apply. Filing Form 706, the Estate Tax Return, for estates exceeding the federal exemption, is required by the IRS. This is advisable, even if the estate doesn’t owe estate taxes. Filing this form is required to transfer any unused exemption to a surviving spouse, a process known as portability. Speak with an estate planning attorney about this issue, as missing this step could create an expensive problem for heirs when the second spouse dies.
The “step-up in basis” rule adjusts the value of any appreciated assets, like stocks or real estate, to reflect the fair market value at the date of the grantor’s death. This can reduce capital gains taxes when heirs sell the assets. To ensure that it is applied correctly, the trustee must obtain accurate date-of-death valuations and properly document them for future tax reporting.
Serving as a trustee is a significant responsibility. Making sure the trustee understands their responsibilities and is willing to carry them out is necessary to ensure the grantor’s wishes are followed. Some estate planning attorneys serve as trustees when no family member or trusted friend is available. There are also professional trustees, although these are generally for high-net-worth families.
