What Is DNI? Distributable Net Income Explained in Plain English
DNI is a tax concept used to help determine how much taxable income an estate or trust can carry out to beneficiaries and the character of that income.
What Matters Most
DNI is not the same thing as cash, accounting income, taxable income, or the amount distributed. Those concepts can overlap without being identical.
DNI Is a Limitation and Character System
DNI generally limits the amount of a fiduciary distribution deduction and corresponding beneficiary income inclusion. It also helps preserve the character of income as it passes to beneficiaries.
DNI Is Not Fiduciary Accounting Income
Accounting income is determined under the governing instrument and applicable law. DNI is a federal income-tax concept. Taxable income is yet another calculation. A preparer needs to keep those systems separate.
Why Professional Help Can Matter
Fiduciary taxation often depends on the governing document, ownership, timing, distributions, elections, fiduciary accounting, and state law. A qualified tax professional with actual estate-and-trust experience can help coordinate those moving pieces so requirements are fulfilled and unintended consequences are less likely.
