Trust distributions can feel confusing. At Casey Lundregan Burns, P.C., we have helped Massachusetts families work through these questions for more than 90 years. Our goal here is simple: show how the principal versus income labels drive your annual payout, who pays the tax, and what choices a trustee has under Massachusetts law.
Principal vs. Income: Overview of Trust Components
Trust principal, sometimes called corpus, is the property originally contributed to the trust, such as cash, stocks, bonds, a house, or a business interest. New contributions are also principal. When the trust sells an asset, the sale proceeds generally replace principal, subject to separate capital gain rules.
Trust income is the earnings the principal produces, such as interest, dividends, rents, and royalties. Some trusts also receive royalties from intellectual property or mineral rights, which count as income unless the governing law or document says otherwise.
The trust document sets the blueprint for which beneficiary receives income, which receives principal, and when they receive said income. If the document is silent or vague, Massachusetts law supplies default rules that the trustee must follow.
With those basics in place, it helps to look at how different rulebooks define income for yearly distribution and for taxes.
Trust Accounting Income (TAI) vs. Taxable Income (TI)
Trust Accounting Income, often shown as TAI on accountings, is an accounting concept governed by the trust document and the Massachusetts Principal and Income Act. Taxable Income, or TI, is defined by the Internal Revenue Code, which controls what goes on the federal tax return.
TAI decides how much income is available to distribute to an income beneficiary in a given year. TI decides how much the trust reports to the IRS, then whether that tax lands with the trust or the beneficiary after distributions.
The Massachusetts Principal and Income Act, known as MPIA, also gives trustees the power to adjust between principal and income when needed to treat beneficiaries fairly. This adjustment power can be vital when a portfolio is invested for total return and traditional income is light.
To see how these labels differ in practice, here are common examples trustees sort through each year:
- Interest and ordinary dividends, counted as TAI and usually included in TI.
- Rents from real estate, counted as TAI and included in TI, net of expenses.
- Capital gains, usually added to principal for TAI, yet included in TI unless excluded by law.
- Trustee fees and expenses, split between income and principal under the document or state law.
These differences set the stage for the tax allocation rule that matches distributions with taxable income.
Simple vs. Complex Trusts: Impact on Distributions
A simple trust must distribute all income each year, make no principal distributions, and make no charitable set-aside deductions. Income is passed out to the beneficiary, and the beneficiary reports it on their personal return.
A complex trust is any trust that does not meet those tests, such as one that allows principal distributions or accumulates income. In a complex trust, taxes get shared between the trust and the beneficiary based on how much is paid out and the DNI limit explained next.
For trustees, these definitions apply year by year. A trust can be a simple one-year trust and complex the next if the principal is distributed or income is accumulated.
To fairly split tax year income between the trust and the beneficiary, the tax code uses one more tool.
Distributable Net Income (DNI): The Driver of Tax Allocation
DNI is the engine that connects distributions to tax reporting. It sets the maximum deduction a trust can claim for distributions and the maximum amount the beneficiary must include in income from that trust.
DNI prevents the same dollars from being taxed twice. The trust deducts distributions up to DNI, and the beneficiary receives a Schedule K-1 that shows the taxable share and its character, such as ordinary income or qualified dividends.
Trustees also have a timing tool called the 65-day rule. A distribution made in the first 65 days of the new year can be elected and treated as if it were made at the end of the prior year, which can smooth taxes when numbers are not final by December 31.
Another big variable that affects DNI and tax bills is capital gains treatment.
How Capital Gains Factor Into Trust Distributions
As a default, capital gains are added to principal for accounting purposes and taxed to the trust, not carried out to the beneficiary. An exception often applies in the final year of the trust, when all remaining items, including gains, are pushed out to the beneficiaries.
Some trust documents or state rules allow a trustee to allocate gains to income in limited circumstances. If gains are allocated to income for accounting, they can enter DNI and move out to beneficiaries with the corresponding tax impact.
Here is a quick example: the trust earns $40,000 in dividends and realizes $60,000 in long-term gains. If gains stay with principal, DNI might be around $40,000 less income-side expenses. If the governing terms allow 50 percent of gains to be treated as income, DNI could jump close to $70,000, which increases the distribution deduction and shifts more tax to the beneficiary’s return.
Whether that move helps depends on the bracket of the trust and each beneficiary, which is why trustee discretion matters.
Trustee Discretion and the Massachusetts Principal and Income Act
Trustees often hold discretion to decide what gets treated as income or principal when the document and law permit. Under the Massachusetts Principal and Income Act, a trustee can adjust between principal and income if needed to act impartially and invest for total return.
The Supreme Judicial Court recently discussed this in In the Matter of the Trusts Under the Will of Helyn W. Kline, SJC-13579. The Court recognized that the MPIA lets trustees invest for total return, then adjust between principal and income to treat current and remainder beneficiaries fairly, and that a proper accounting adjustment is not the same thing as a principal distribution barred by the instrument.
In short, the MPIA supports practical, even-handed decisions. This helps trustees avoid chasing yield at the cost of growth or taxes, and it can reduce disputes.
Minimizing Overall Tax Obligations
Trusts reach the top federal income tax bracket at far lower levels than individual taxpayers. That means a dollar taxed inside the trust can carry a higher rate than the same dollar taxed to a beneficiary.
When the document allows, distributing income to beneficiaries in lower brackets can reduce family-wide taxes. The trust generally deducts the distributed DNI, which lowers its taxable income, and the beneficiary reports the income on their return using the K-1.
Practical steps can help keep tax friction down while staying faithful to the trust’s terms:
- Review distribution provisions early in the year, and use the 65-day rule when timing is helpful.
- Match investments to the trust’s payout design, such as favoring growth when an adjustment power is available under the MPIA.
- Coordinate with beneficiaries on estimated taxes, especially if a large K-1 is expected.
None of this replaces the trust’s unique instructions, but it keeps the tax piece from working against your goals.
