A trust is used to control how assets transfer after death. When the grantor dies, the trust becomes an active legal entity. The trustee follows the trust terms, manages assets, distributes property to beneficiaries and handles required tax filings. How this process works depends on the trust type and the instructions in the trust document.
If you need help with trust administration or post-death asset management, a financial advisor can work with you on setting up a plan to distribute investments and tax reporting.
What Happens When a Grantor Dies
When a grantor, passes away, the trust enters a new phase. The first thing that happens depends on what type of trust the grantor had established. If it’s a revocable living trust, the trust typically becomes irrevocable upon the grantor’s death. This means that no one can make changes to its terms or beneficiaries from that point forward. For irrevocable trusts, which were already fixed during the grantor’s lifetime, the death primarily triggers the distribution and administration process according to the trust’s instructions.
One of the most important transitions after a grantor’s death is the shift in control from the grantor to the successor trustee. This individual, chosen by the grantor, is responsible for carrying out the trust’s terms. Their duties may include notifying beneficiaries, gathering and valuing assets, paying outstanding debts or taxes and distributing assets. The successor trustee essentially steps into the grantor’s shoes, but with a fiduciary obligation to act solely in the best interests of the beneficiaries.
After taking control, the trustee begins to manage and eventually distribute the trust’s assets. In many cases, this involves liquidating certain investments, transferring property titles or setting up ongoing management for assets intended to provide income to beneficiaries. The trustee must also address key tax and legal matters. When the grantor dies, the trust may need to file its own tax return and pay any estate or income taxes owed.
Asset Transfers and Distributions After a Grantor Dies

One of the most important steps in settling an estate is transferring the assets held within the trust. Because the trust, not the individual, legally owns those assets, they don’t go through probate. This is a major advantage of having a trust in the first place. Instead, the successor trustee immediately assumes authority and can begin managing and distributing property according to the grantor’s instructions.
The successor trustee starts by gathering all records related to the trust, including titles, deeds, investment accounts and insurance policies. They notify financial institutions of the grantor’s death and provide documentation proving their legal authority to act on behalf of the trust. This allows trust-owned assets, including real estate, investments and personal property, to be identified, valued and prepared for transfer.
Once debts and taxes are addressed, the trustee distributes the remaining assets. Depending on the trust’s terms, this might involve transferring ownership of property, distributing cash from investment accounts or continuing to manage assets for beneficiaries over time. Some trusts provide immediate lump-sum payments. Meanwhile, others establish ongoing income distributions or milestone-based transfers, such as releasing funds to a child at certain ages.
Tax Reporting Requirements When a Grantor Dies
A grantor’s passing triggers several important tax obligations for both the trust and the estate. The first step is to determine whether the trust must now file its own income tax return. A revocable living trust, which previously used the grantor’s Social Security number, typically becomes a separate tax entity at death. The successor trustee must obtain a new taxpayer identification number from the IRS. Additionally, they must begin filing Form 1041, the U.S. Income Tax Return for Estates and Trusts, to report any income the trust earns after the grantor’s death.
In addition to trust income taxes, federal or state estate taxes may apply, depending on the value of the grantor’s assets. The IRS requires the filing of Form 706, the Estate Tax Return, for estates exceeding the federal exemption threshold, which adjusts periodically based on inflation. Even if no tax is ultimately owed, filing may be necessary to transfer any unused exemption to a surviving spouse, known as portability. Some states also impose their own estate or inheritance taxes, which trustees or executors must carefully evaluate.
One major tax event that occurs at death is the “step-up in basis.” This rule adjusts the value of appreciated assets, like stocks or real estate, to reflect their fair market value at the date of death. The step-up can significantly reduce capital gains taxes when heirs later go to sell those assets. To apply it correctly, the trustee must obtain accurate date-of-death valuations and document them thoroughly for future tax reporting.
Bottom Line

When a grantor dies, the trust becomes the primary structure for settling their financial affairs. Assets held in the trust typically avoid probate, allowing a faster and more private transfer to beneficiaries. The successor trustee is responsible for legal and tax tasks, including filing required returns and valuing and distributing assets. Professional support can help reduce errors during this process.
