DNI Calculation Breakdown
How Trust DNI Works
DNI is the central concept in trust income taxation. It determines how much tax the trust pays versus how much is shifted to beneficiaries. Because trust tax brackets are so compressed (37% kicks in above ~$14,450 in 2026), distributing income to lower-bracket beneficiaries can produce significant tax savings.
DNI Formula
DNI = Ordinary Income + Tax-Exempt Interest β Expenses β Net Capital Gains (unless distributed)
Distribution Deduction = Lesser of (Distributions, DNI)
Trust Taxable Income = Gross Income β Distribution Deduction β Exemption β Capital Losses Used
Beneficiary Inclusion = Their share of DNI (by proportion of distribution)
Distribution Deduction = Lesser of (Distributions, DNI)
Trust Taxable Income = Gross Income β Distribution Deduction β Exemption β Capital Losses Used
Beneficiary Inclusion = Their share of DNI (by proportion of distribution)

Frequently Asked Questions
What is Distributable Net Income (DNI) for a trust?
Distributable Net Income (DNI) under IRC Section 643 serves two critical functions: (1) it sets the maximum amount that beneficiaries must include in their gross income when they receive trust distributions, and (2) it limits the deduction the trust can take for distributions made to beneficiaries. DNI also determines the character (ordinary income, capital gains, tax-exempt interest) of income passed through to beneficiaries.
How is DNI calculated?
DNI generally equals trust accounting income plus or minus certain adjustments: start with trust gross income, subtract deductible expenses, add back any deduction for net capital gains (capital gains are usually excluded from DNI unless allocated to income), subtract tax-exempt interest not included in gross income but add it back as a component. The simplified formula is: Ordinary income + Dividends + Tax-exempt interest - Expenses - Net capital gains (if not distributed or held in trust).
What is the distribution deduction for a trust?
Under IRC Section 661, a simple or complex trust deducts the lesser of: (1) the amount actually distributed to beneficiaries, or (2) the trust's DNI. If the trust distributes less than DNI, it deducts only what was distributed. If it distributes more than DNI, the deduction is limited to DNI. The trust pays tax on any income retained (not distributed), and beneficiaries pay tax on the distributed amounts.
How does the character pass-through work on K-1s?
Each item of DNI retains its character when passed through to beneficiaries. For example, if DNI includes both qualified dividends and ordinary interest, each beneficiary receives a proportionate share of each character. Capital gains that are part of DNI also retain their capital gain character. Tax-exempt interest retains its tax-exempt character for the beneficiary. This is reported on Schedule K-1 (Form 1041).
What is trust taxable income and when does the trust itself pay tax?
A trust pays income tax on its undistributed net income β the income it retains rather than distributing. Trusts face highly compressed tax brackets: in 2026, the 37% rate applies above approximately $14,450 of undistributed income (compared to $626,350+ for married individuals). This makes it generally disadvantageous for trusts to accumulate income. Distributions to beneficiaries in lower brackets can dramatically reduce the overall tax burden on trust income.
