Trust Accounting Income vs. Principal

How a California trust or estate divides receipts and disbursements between income and principal under the Uniform Fiduciary Income and Principal Act, and how it differs from DNI and taxable income.

Why it matters

When a trust or estate has an income beneficiary and a remainder beneficiary, each receipt and each disbursement belongs to one or the other: income, which the income beneficiary receives, or principal, which is kept for the remainder. The amount allocated to income, often called trust accounting income or fiduciary accounting income, decides what the income beneficiary is paid. When there are income beneficiaries, the accounting includes a schedule allocating receipts and disbursements between principal and income (Prob. Code §1063(c)).

The rules: California’s Uniform Fiduciary Income and Principal Act

California’s act is Probate Code §§16320–16383. The trust instrument’s own terms come first; the act supplies the rules where the instrument is silent. Some of the main ones:

Trust accounting income vs. DNI and taxable income

Trust accounting income is a fiduciary-law measure: what the income beneficiary is entitled to. Distributable net income (DNI) and taxable income are tax measures, used on the trust’s income tax returns, and they can differ from it; for example, capital gains are usually principal for accounting purposes but still taxable. The trust’s CPA works from both.
