What Happens to Undistributed Income When a Trust Income Interest Ends

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

When a mandatory income interest in a trust ends, the trustee must pay the beneficiary's share of any undistributed income to that beneficiary or their estate. There is an exception: if the beneficiary held a broad power to revoke more than five percent of the trust, the undistributed income is added to principal instead.

Title 14, TRUST ADMINISTRATION

azleg.gov

Final Accounting for Mandatory Income Beneficiaries

When a mandatory income interest ends, typically because the beneficiary has passed away, the trustee does not simply stop payments and move on. Any income that was received but not yet distributed must still be accounted for. The beneficiary who survived the end date, or the estate of a beneficiary whose death triggered the termination, is entitled to their share of that undistributed income.

When a mandatory income interest ends, the trustee shall pay to a mandatory income beneficiary who survives that date, or the estate of a deceased mandatory income beneficiary whose death causes the interest to end, the beneficiary's share of the undistributed income that is not disposed of under the terms of the trust unless the beneficiary has an unqualified power to revoke more than five per cent of the trust immediately before the income interest ends.

A.R.S. § 14-7409(A)

The exception for beneficiaries who held a broad revocation power makes sense in context. If the beneficiary could have pulled out more than five percent of the trust at any time, they had the functional equivalent of ownership over that portion. In that case, the undistributed income from the revocable portion folds back into principal rather than being paid out separately.

Annuities and the Definition of Undistributed Income

For trusts that pay a fixed annuity or a fixed percentage of asset value, the rules are slightly different. When that obligation ends, the trustee prorates the final payment as needed to satisfy tax requirements or other purposes specified in the trust document.

The statute also clarifies what "undistributed income" means in this context: it includes net income received before the income interest ended, but does not include items that are due or accrued, or income that has already been added to principal under the trust terms. This definition prevents disputes over whether certain items should be treated as income owed to the departing beneficiary or principal belonging to the trust going forward.

A. When a mandatory income interest ends, the trustee shall pay to a mandatory income beneficiary who survives that date, or the estate of a deceased mandatory income beneficiary whose death causes the interest to end, the beneficiary's share of the undistributed income that is not disposed of under the terms of the trust unless the beneficiary has an unqualified power to revoke more than five per cent of the trust immediately before the income interest ends. In the latter case, the undistributed income from the portion of the trust that may be revoked must be added to principal. B. When a trustee's obligation to pay a fixed annuity or a fixed fraction of the value of the trust's assets ends, the trustee shall prorate the final payment to the extent required by applicable law to accomplish a purpose of the trust or its settlor relating to income, gift, estate or other tax requirements. C. For the purposes of this section, "undistributed income" means net income received before the date on which an income interest ends and does not include an item of income or expense that is due or accrued or net income that has been added or is required to be added to principal under the terms of the trust.

Related Questions

What does a trustee actually do?

A trustee manages trust assets according to the rules the trust creator set. While you are alive, you are typically both trustor and trustee. After you pass, your successor trustee distributes assets as instructed.

What is a Revocable Living Trust and how does it work?

A Revocable Living Trust lets you transfer asset ownership into a trust you control during your lifetime. When you pass, a successor trustee distributes assets to beneficiaries without probate.

Do beneficiary designations override my will?

Yes. Retirement accounts like 401(k)s, IRAs, and life insurance pass by beneficiary designation, not by your will. If an old beneficiary is listed, that designation overrides your current plan.
