Arizona Trust Principal and Income Act: Key Definitions

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

Arizona's Uniform Principal and Income Act defines the key terms that govern how trust income and principal are managed. These definitions set the foundation for how trustees allocate receipts and expenses between current beneficiaries (who receive income) and future beneficiaries (who receive principal when the trust ends).

Title 14, TRUST ADMINISTRATION

azleg.gov

Income vs. Principal: The Core Distinction

When a trust holds assets, some of those assets generate current returns, like dividends, interest, or rent. Under this statute, those returns are classified as "income." The underlying assets themselves, held for future distribution when the trust terminates, are classified as "principal." Getting this distinction right matters because income beneficiaries and remainder beneficiaries have competing interests.

"Income" means money or property that a fiduciary receives as current return from a principal asset and includes a portion of receipts from a sale, exchange or liquidation of a principal asset, to the extent provided in sections 14-7410 through 14-7424.

A.R.S. § 14-7401(4)

An income beneficiary is someone entitled to receive net income from the trust during its term. A remainder beneficiary is the person who receives the principal when the income interest ends. In many family trusts, a surviving spouse receives income for life, and the children receive the principal after the spouse passes.

Fiduciary, Trustee, and the Accounting Period

The statute defines "fiduciary" broadly. It includes personal representatives, trustees, executors, administrators, and anyone performing substantially the same role. This means the principal and income rules can apply both during trust administration and during estate settlement.

"Fiduciary" means a personal representative or a trustee and includes an executor, an administrator, a successor personal representative, a special administrator and a person performing substantially the same function.

A.R.S. § 14-7401(3)

The accounting period defaults to a calendar year but can be a different twelve-month period chosen by the fiduciary. It also includes partial periods at the beginning or end of an income interest. These definitions work together to create a consistent framework for trustees to follow when deciding what goes to income beneficiaries now and what stays in principal for remainder beneficiaries later.

In this article, unless the context otherwise requires: 1. "Accounting period" means a calendar year unless another twelve month period is selected by a fiduciary and includes a portion of a calendar year or other twelve month period that begins when an income interest begins or ends when an income interest ends. 2. "Beneficiary" includes, in the case of a decedent's estate, an heir, legatee and devisee and, in the case of a trust, an income beneficiary and a remainder beneficiary. 3. "Fiduciary" means a personal representative or a trustee and includes an executor, an administrator, a successor personal representative, a special administrator and a person performing substantially the same function. 4. "Income" means money or property that a fiduciary receives as current return from a principal asset and includes a portion of receipts from a sale, exchange or liquidation of a principal asset, to the extent provided in sections 14-7410 through 14-7424. 5. "Income beneficiary" means a person to whom net income of a trust is or may be payable. 6. "Income interest" means the right of an income beneficiary to receive all or part of net income, whether the terms of the trust require it to be distributed or authorize it to be distributed in the trustee's discretion. 7. "Mandatory income interest" means the right of an income beneficiary to receive net income that the terms of the trust require the fiduciary to distribute. 8. "Net income" means the total receipts allocated to income during an accounting period minus the disbursements made from income during the period, plus or minus transfers under this article to or from income during the period. 9. "Person" means any individual, corporation, business trust, estate, trust, partnership, limited liability company, association, joint venture, government, governmental subdivision, agency or instrumentality, public corporation or other legal or commercial entity. 10. "Principal" means property held in trust for distribution to a remainder beneficiary when the trust terminates. 11. "Remainder beneficiary" means a person entitled to receive principal when an income interest ends. 12. "Terms of a trust" means the manifestation of the intent of a settlor or decedent with respect to the trust expressed in a manner that admits of its proof in a judicial proceeding, whether by written or spoken words or by conduct. 13. "Trustee" includes an original, additional or successor trustee, whether or not appointed or confirmed by a court.

Does my trust need its own EIN, or can I use my Social Security number?

While you are alive, your revocable trust uses your Social Security number. After you pass away, the trust needs its own EIN from the IRS because it becomes a separate legal entity.

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.
