A trustee’s power to adjust between principal and income lets the trustee reclassify amounts from one account to the other so that income beneficiaries and remainder beneficiaries are treated fairly, even when the trust’s investments produce most of their return through capital appreciation rather than cash. The authority comes from state law, usually a version of the Uniform Principal and Income Act (UPIA) or its successor, the Uniform Fiduciary Income and Principal Act (UFIPA). It is not an open-ended tool. The trustee must satisfy specific prerequisites, weigh a defined list of factors, respect a set of flat prohibitions, and in most states give beneficiaries notice before acting.
Why the Power Exists
Every trust with both an income beneficiary and a remainder beneficiary creates built-in tension. The income beneficiary receives ongoing distributions during the trust’s life. The remainder beneficiary inherits whatever is left when it ends. Fiduciary law’s duty of impartiality requires the trustee to treat both groups fairly, and that gets hard when the portfolio’s returns don’t cooperate.
Older trust portfolios leaned on bonds and dividend-paying stocks that threw off cash. The trustee could invest for yield, pay income to one beneficiary, and preserve principal for the other. Modern portfolios lean on growth stocks, index funds, and other assets that build value through capital appreciation. In a strong year, principal might gain 8% while the income account receives almost nothing.
Without the power to adjust, the trustee has to pick between abandoning the better investment strategy to chase yield, or sticking with total-return investing while the income beneficiary gets shortchanged. The power resolves that by letting the trustee move a portion of capital gains or other principal into the income account, or occasionally the reverse, as an accounting correction.
The Three Prerequisites
The UPIA, codified in most states as Section 104, sets three conditions that all must be met before any adjustment is permissible.
First, the trustee must be investing under the prudent investor rule. That standard requires diversification, attention to risk and return across the full portfolio, and decisions aimed at the beneficiaries’ collective best interests rather than any one holding’s performance in isolation.
Second, the trust document must tie distributions to the trust’s “income.” If the instrument instead directs a fixed dollar amount or a set percentage of total value, there is no mismatch to resolve and the power does not apply. The whole point is to bridge the gap between what the trust calls income and what modern investments actually produce.
Third, the trustee must determine that even after following the prudent investor rule and applying the standard accounting rules for allocating receipts and disbursements, the trust still cannot be administered impartially. That is the trigger: everything else is right and the split between income and remainder beneficiaries still comes out lopsided.
Documentation matters. If a beneficiary or a court later questions the adjustment, the trustee needs a paper trail showing that each condition was satisfied. Many practitioners prepare a written memorandum before acting, walking through each prerequisite and the reasoning behind the specific dollar amount shifted.
Factors the Trustee Must Weigh
Once the prerequisites are met, the trustee must consider a series of factors before deciding how large an adjustment to make. The UPIA lists nine, and the analysis is fact-specific.
- The trust’s purpose and expected duration. A trust designed to last 40 years calls for different treatment than one winding down in three.
- The settlor’s intent, as shown in the trust language and any outside evidence of what the person who created the trust wanted.
- Beneficiary circumstances, including age, health, other income, and financial needs of both current and future beneficiaries.
- Liquidity needs, meaning whether the trust holds easily sold financial assets or illiquid property like real estate or closely held business interests.
- Asset composition, including the mix of financial assets versus tangible property, whether assets were purchased or inherited, and whether a beneficiary is personally using any trust asset.
- Net accounting income versus principal growth, weighing what the trust’s other allocation rules already produce against the change in principal value.
- Existing invasion or accumulation powers already in the trust document and how often they have been used.
- Economic conditions, including the effect of inflation or deflation on the purchasing power of both the income stream and the principal.
- Tax consequences for the trust and its beneficiaries, including income, estate, and gift tax effects.
No single factor controls. A trustee who fixates on one at the expense of the others is exposed to a claim of abuse of discretion. The analysis is meant to produce a balanced decision that holds up on review.
When the Power Cannot Be Used
Section 104 also lists flat prohibitions. These are situations where an adjustment is off-limits regardless of how the factors balance.
Marital Deduction Trusts
A trust designed to qualify for the federal estate tax marital deduction must give the surviving spouse all of the trust’s income, paid at least annually. An adjustment that reduces the income interest could disqualify the trust and trigger a large estate tax bill. The restriction covers both the general power of appointment marital trust and the qualified terminable interest property (QTIP) trust.1Office of the Law Revision Counsel. 26 USC 2056 – Bequests, Etc., to Surviving Spouse
Charitable Trusts
Trusts structured to produce a charitable income tax deduction face similar limits. A charitable remainder trust must pay either a fixed annuity or a fixed percentage of trust assets to the non-charitable beneficiary, with the remainder to charity. An adjustment that changes those amounts could destroy the deduction. The same logic applies to amounts permanently set aside for charitable purposes; the trustee cannot adjust those funds away from their intended recipient.2Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts
Trustee Who Is Also a Beneficiary
A trustee who is also a beneficiary of the trust generally cannot exercise the power to adjust. The IRS could treat the adjustment as a general power of appointment, meaning the trustee could effectively direct trust assets to themselves. Under federal estate tax law, a general power of appointment causes the entire trust to be included in the holder’s taxable estate at death.3Office of the Law Revision Counsel. 26 USC 2041 – Powers of Appointment The usual workaround is to appoint an independent co-trustee to handle adjustment decisions.
Grantor Trust Status
An adjustment is also prohibited if having or using the power would cause someone to be treated as the owner of the trust for income tax purposes when they otherwise would not be. This keeps the power from inadvertently turning a non-grantor trust into a grantor trust and shifting the whole tax burden onto an individual who was never meant to bear it.
Tax Effects of an Adjustment
A principal-to-income adjustment is an accounting reclassification, not a taxable event in itself. But it has real tax consequences because it changes what counts as trust accounting income, which drives how much the trust must distribute and how distributions are taxed.
The Internal Revenue Code defines trust “income” by reference to the governing instrument and applicable state law.4Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D When a trustee exercises the power to adjust and moves capital gains into the income account, state law treats those gains as income. The IRS respects that reclassification as long as it reflects a reasonable apportionment of the trust’s total return between income and remainder beneficiaries, made under a state statute that authorizes the adjustment when the trustee is investing under the prudent investor standard.5eCFR. 26 CFR 1.643(b)-1 – Definition of Income
That reclassification can shift capital gains into the trust’s distributable net income. Ordinarily, capital gains stay at the trust level and are taxed to the trust. When a trustee allocates them to income through a reasonable exercise of discretion under state law, those gains can flow through to beneficiaries on Schedule K-1.6eCFR. 26 CFR 1.643(a)-3 – Capital Gains and Losses Because trusts hit the top income tax bracket at low income levels, pushing gains out to beneficiaries in lower brackets can produce meaningful tax savings.
Once a trustee begins treating capital gains as part of distributable net income, the IRS requires consistent treatment in future years. Switching back and forth invites an audit. A trustee who switches from traditional income accounting to the power-to-adjust method, or later to a unitrust, does not trigger a Section 1001 recognition event, and the switch does not create a taxable gift from the grantor or any beneficiary, provided the trust complies with all requirements of the authorizing state statute.5eCFR. 26 CFR 1.643(b)-1 – Definition of Income A method change made through a court order or non-judicial settlement that falls outside the state statute may trigger gain or gift tax consequences depending on the facts.
Notice to Beneficiaries and Judicial Review
Before finalizing an adjustment, the trustee must notify the trust’s beneficiaries. Specifics vary by state, but the general framework requires written notice to all qualified beneficiaries, both current and remainder. The notice describes the proposed adjustment and gives beneficiaries a window, commonly 30 to 60 days, to object in writing.
If no one objects, the trustee proceeds. If a beneficiary objects, the trustee typically must petition the court for approval before acting. Skipping notice entirely can void the adjustment and expose the trustee to personal liability for breach of fiduciary duty.
When disputes reach court, judges do not substitute their own judgment for the trustee’s. Review is limited to whether the trustee abused their discretion, meaning they acted in bad faith, from improper motives, or in a way no reasonable fiduciary would consider appropriate. A trustee who documented the analysis, considered the statutory factors, and reached a defensible conclusion almost always survives scrutiny. Problems arise when trustees skip the analysis, fail to document, or adjust in a way that transparently favors one beneficiary class.
Risk also runs in the other direction. A trustee who refuses to consider whether an adjustment is warranted can face claims from income beneficiaries receiving inadequate distributions while principal grows unchecked. They can seek to compel action or remove the trustee for failing the duty of impartiality. The power is discretionary, but ignoring it is not the same as exercising discretion.
Unitrust Conversion as an Alternative
The power to adjust requires a case-by-case decision each time the trustee wants to reallocate. For trustees who find that burdensome or who want more predictability, converting the trust to a total return unitrust is often the better path.
A unitrust distributes a fixed percentage of the trust’s total asset value each year, regardless of accounting income. If the trust is worth $2 million and the unitrust rate is 4%, the income beneficiary receives $80,000, whether that came from dividends, interest, capital gains, or some combination. The income-versus-principal distinction effectively disappears for distribution purposes.
Most states with unitrust statutes set the permissible rate between 3% and 5% of fair market value, and the IRS treats a rate in that range as a reasonable apportionment of total return.5eCFR. 26 CFR 1.643(b)-1 – Definition of Income Trusts that qualify for the marital deduction, the charitable deduction, or the generation-skipping transfer tax exemption are generally locked into that 3% to 5% corridor even in states that otherwise allow more flexibility.
Conversion is not permanent. State statutes typically allow reconversion back to a traditional income trust if circumstances change. Both conversion and reconversion require notice to beneficiaries and may require court approval if any beneficiary objects. Once a trust converts, the power to adjust is no longer available because there is no longer a meaningful income-versus-principal line to adjust across.
UPIA Versus UFIPA
The Uniform Principal and Income Act dates to 1997 and has been the dominant framework for decades. In 2018, the Uniform Law Commission approved a replacement: the Uniform Fiduciary Income and Principal Act. A growing number of states have adopted UFIPA.
The most significant change for trustees is that UFIPA lowers the bar for exercising the power to adjust. Under the UPIA, the trustee had to show that impartial administration was impossible without the adjustment. UFIPA requires only that the adjustment “assist” the fiduciary in administering the trust impartially. That shift from necessity to helpfulness gives trustees more room to act.
UFIPA also folds the unitrust conversion power into the same act, in Article 3, where most states had previously handled it through a separate statute. The new act gives fiduciaries broader flexibility to set unitrust percentages and determine valuation methods, though trusts with special tax benefits still fall within the 3% to 5% annual rate limit.
In states that have not adopted UFIPA, the UPIA framework still controls. In states that have, the core concepts carry over: the duty of impartiality, the prudent investor rule, the list of factors, and the tax-driven prohibitions. The procedural requirements are more streamlined, and the trigger for using the power is easier to meet.
