How Trust Income Taxes Are Allocated Between Principal and Income

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

When a trust owes income taxes, the trustee must decide whether to pay those taxes from trust income or from principal. Arizona law ties the answer to where the underlying receipts were allocated. If the receipts went to income, the tax comes from income. If they went to principal, the tax comes from principal.

Title 14, TRUST ADMINISTRATION

Matching Taxes to Their Source

Trust taxation is not a single line item. Different receipts within the same trust can be classified differently for accounting purposes. Some go to income (interest, dividends, rent). Others go to principal (capital gains from asset sales). This statute creates a straightforward rule: the tax follows the receipt. Whatever generated the tax liability is the fund that pays it.

A tax required to be paid by a trustee based on receipts allocated to income must be paid from income.

A.R.S. § 14-7429(A)

This principle keeps the trust fair. Income beneficiaries bear the tax cost of income they receive, and remainder beneficiaries bear the tax cost of gains that build principal. Neither side subsidizes the other.

Entity Income and Mixed Allocations

Trusts often hold interests in entities like partnerships or S corporations. Those entities produce taxable income that may be allocated partly to income and partly to principal. Arizona law handles the split proportionally: the trust pays the tax from each fund in the same ratio that receipts were allocated to each fund. If the tax exceeds the total receipts from the entity, the excess comes from principal.

A tax required to be paid by a trustee on the trust's share of an entity's taxable income must be paid proportionately from principal and income to the extent that receipts from the entity are allocated to both income and principal.

A.R.S. § 14-7429(C)(3)

The statute also requires one more adjustment. After the initial allocation, the trustee must account for any tax deduction the trust receives because of distributions to beneficiaries. If a distribution lowers the trust's overall tax bill, the trustee adjusts income or principal receipts to reflect that benefit.

14-7429. Income taxes A. A tax required to be paid by a trustee based on receipts allocated to income must be paid from income. B. A tax required to be paid by a trustee based on receipts allocated to principal must be paid from principal, even if the tax is called an income tax by the taxing authority. C. A tax required to be paid by a trustee on the trust's share of an entity's taxable income must be paid: 1. From income to the extent that receipts from the entity are allocated to income. 2. From principal to the extent that receipts from the entity are allocated only to principal. 3. Proportionately from principal and income to the extent that receipts from the entity are allocated to both income and principal. 4. From principal to the extent that the tax exceeds the total receipts from the entity. D. After applying subsections A, B and C, the trustee shall adjust income or principal receipts to the extent that the trust's taxes are reduced because the trust receives a deduction for payments made to a beneficiary.

Related Questions

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.

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.
