6.2 Principal and Income Accounting: UFIPA and Power to Adjust
Key Takeaways
- Fiduciary accounting separates trust receipts and disbursements into Income (Fiduciary Accounting Income - FAI) for current beneficiaries and Principal (Corpus) for remainder beneficiaries, following a strict hierarchy: trust terms govern first, followed by statutory default acts (UPAIA/UFIPA).
- Receipt allocations under standard statutory defaults assign ordinary cash dividends, bond coupon interest, and net rental operating income to Income, while assigning capital gains, stock dividends/splits, liquidating distributions, and property sale proceeds to Principal.
- Disbursement rules mandate that ongoing recurring management expenses (trustee fees, accounting, investment advisory costs) are split 50/50 between Income and Principal, whereas ordinary maintenance and real estate taxes are 100% Income expenses, and capital improvements, mortgage principal, and transfer taxes are 100% Principal expenses.
- Under the Trustee Power to Adjust (UPAIA § 104 / UFIPA § 203), a trustee managing for total return under UPIA may reallocate between income and principal to preserve impartiality, provided the adjustment does not violate strict tax prohibitions (e.g., jeopardizing QTIP marital deductions or CRT status).
- A Total Return Unitrust (TRU) conversion replaces traditional FAI accounting by paying a fixed annual statutory percentage (3% to 5% of smoothed net fair market value) pursuant to Treas. Reg. § 1.643(b)-1, eliminating conflicts between yield generation and capital appreciation.
Principal and Income Accounting: UFIPA and Power to Adjust
Quick Answer: Fiduciary accounting separates receipts and expenses into Income (for the current beneficiary) and Principal (for the remainder beneficiary). Under UPAIA and UFIPA, ordinary cash dividends, bond interest, and net rents belong to Income, whereas capital gains, stock dividends, and sales proceeds belong to Principal. Routine management fees are split 50/50. To implement Modern Portfolio Theory without shortchanging income beneficiaries, trustees may exercise the Power to Adjust or convert to a Total Return Unitrust (TRU) (distributing 3%–5% of smoothed market value).
1. The Fiduciary Accounting Hierarchy and Core Concepts
Fiduciary accounting is distinct from financial accounting (GAAP) and federal income tax accounting (Subchapter J). It is governed by state law to resolve the inherent economic tension between the Current Income Beneficiary (who receives net yield) and the Remainder Beneficiary (who preserves trust corpus).

Key Fiduciary Income Tax Terms
- Fiduciary Accounting Income (FAI): Net income of the trust determined under governing trust terms and local principal/income law. This represents the actual cash flow distributable to the income beneficiary.
- Taxable Income: Net income computed under the Internal Revenue Code (Form 1041).
- Distributable Net Income (DNI): The statutory ceiling under IRC § 643(a) that limits the trust's income distribution deduction and determines the maximum amount taxable to beneficiaries.
2. Allocation of Receipts: Income vs. Principal
Under the Uniform Principal and Income Act (UPAIA § 401–§ 415) and the Uniform Fiduciary Income and Principal Act (UFIPA § 401–§ 415), receipts are allocated as follows:
┌─────────────────────────────────────────────────────────────────────────────┐
│ ALLOCATION OF FIDUCIARY RECEIPTS │
├──────────────────────────────────────┬──────────────────────────────────────┤
│ ALLOCATED TO INCOME (FAI) │ ALLOCATED TO PRINCIPAL │
├──────────────────────────────────────┼──────────────────────────────────────┤
│ • Ordinary cash dividends │ • Capital gains & sales proceeds │
│ • Bond interest & coupon payments │ • Stock splits & stock dividends │
│ • Net rental income from real estate │ • Liquidating corporate dividends │
│ • Net business operating profits │ • Property insurance claim proceeds │
│ • Short-term money market interest │ • Bond principal & par redemptions │
└──────────────────────────────────────┴──────────────────────────────────────┘
Specialized Asset Receipts Allocation Rules
- Corporate Distributions (UPAIA § 401):
- Ordinary cash dividends = 100% Income.
- Stock dividends (shares received in lieu of cash), stock splits, and liquidating distributions (recapitalization, merger proceeds, or liquidation) = 100% Principal.
- Bonds and Debt Obligations (UPAIA § 405):
- Periodic coupon interest payments = 100% Income.
- Principal repayment at maturity or call redemption = 100% Principal.
- Zero-coupon bond original issue discount (OID) accretions = Allocated to income upon redemption/sale if realized.
- Natural Resources (Minerals, Oil, Gas, Timber - UPAIA § 411 / UFIPA § 411):
- Operating delay rentals = 100% Income.
- Production royalties and net working interests = 90% Principal / 10% Income under UPAIA (modern UFIPA provides flexible percentage allocations reflecting asset depletion).
- Liquidating Assets (Patents, Copyrights, Royalties, Leaseholds - UPAIA § 410):
- Receipts from assets whose value diminishes over time = 10% Income / 90% Principal.
- Retirement Plans and Deferred Compensation (UPAIA § 409 / UFIPA § 409):
- Distributions from traditional IRAs or 401(k) plans = To the extent the payor characterizes the payment as interest/dividends (internal income), it is Income; otherwise, a default statutory rule treats up to 10% as Income and 90% as Principal (or 4% unitrust value under modern UFIPA regulations for marital deduction compliance under Rev. Rul. 2006-26).
3. Allocation of Disbursements: Income vs. Principal Expenses
Disbursements represent the costs of managing, maintaining, and administering trust property. Under UPAIA §§ 501–502 and UFIPA §§ 501–502, expenses are allocated according to their ongoing versus permanent nature:
┌─────────────────────────────────────────────────────────────────────────────┐
│ ALLOCATION OF FIDUCIARY DISBURSEMENTS │
├──────────────────────────────────────┬──────────────────────────────────────┤
│ CHARGED TO INCOME (50%) │ CHARGED TO PRINCIPAL (50%) │
├──────────────────────────────────────┴──────────────────────────────────────┤
│ • 50% of Trustee Compensation and Fiduciary Administration Fees │
│ • 50% of Investment Advisory, Custodial, and Management Expenses │
│ • 50% of Routine Fiduciary Accounting and Tax Preparation Fees │
├──────────────────────────────────────┬──────────────────────────────────────┤

4. The Trustee Power to Adjust (UPAIA § 104 / UFIPA § 203)
The Modern Portfolio Theory Dilemma
Under the Uniform Prudent Investor Act (UPIA), trustees are legally mandated to invest for Total Return (capital appreciation plus current yield) across the entire portfolio. However, investing heavily in growth equities creates minimal cash dividends, starving the income beneficiary. Conversely, tilting the portfolio toward high-yield bonds erodes principal purchasing power due to inflation, harming remainder beneficiaries.
To resolve this structural conflict, the Uniform Law Commission created the Trustee Power to Adjust (UPAIA § 104; UFIPA § 203).
┌─────────────────────────────────────────────────────────────────────────────┐
│ THREE PREREQUISITES FOR POWER TO ADJUST (UPAIA § 104) │
├─────────────────────────────────────────────────────────────────────────────┤
│ 1. UPIA INVESTMENT MANDATE │
│ • Trustee must invest and manage trust assets under the Uniform Prudent │
│ Investor Act (total return investment strategy). │
│ 2. TRADITIONAL INCOME DISTRIBUTION STANDARD │
│ • Trust terms describe distribution amounts by referencing 'income' │
│ (e.g., 'distribute all net income annually to my spouse'). │
│ 3. INABILITY TO SATISFY DUTY OF IMPARTIALITY (UTC § 803) │
│ • Trustee determines that, after applying standard statutory allocation │
│ rules, the trustee cannot administer the trust impartially. │
└─────────────────────────────────────────────────────────────────────────────┘
Statutory Prohibitions and Tax Disqualification Traps
A trustee CANNOT exercise the power to adjust under any of the following statutory carve-outs (UPAIA § 104(c)):
- Marital Deduction Disqualification: If adjusting would diminish or disqualify a marital deduction trust under IRC § 2056(b)(7) (QTIP Trust) or IRC § 2523;
- Charitable Trust Disqualification: If adjusting would disqualify a Charitable Remainder Unitrust (CRUT) or Charitable Remainder Annuity Trust (CRAT) under IRC § 664;
- Beneficiary as Trustee (General Power of Appointment): If the trustee is a current or remainder beneficiary, possessing the power to adjust would give the trustee a General Power of Appointment under IRC § 2041, causing the entire trust corpus to be included in the trustee-beneficiary's gross estate;
- Grantor Trust Status: If possessing or exercising the power would cause the grantor to be treated as owner under IRC §§ 671–679.
5. Total Return Unitrust (TRU) Conversions
As an alternative to discretionary adjustments under UPAIA § 104, modern trust statutes authorize the conversion of a traditional "net income" trust into a Total Return Unitrust (TRU).
┌─────────────────────────────────────────────────────────────────────────────┐
│ TOTAL RETURN UNITRUST (TRU) MECHANICS │
├──────────────────────────────────────┬──────────────────────────────────────┤
│ TRADITIONAL INCOME TRUST │ TOTAL RETURN UNITRUST (TRU) │
├──────────────────────────────────────┼──────────────────────────────────────┤
│ • Beneficiary receives actual net │ • Beneficiary receives fixed % │
│ dividends, interest, and rents │ (typically 3% to 5%) of net FMV. │
│ • Portfolio distorted toward yield │ • Portfolio invested 100% for total │
│ • Frequent beneficiary conflicts │ return without asset class bias. │

Treasury Regulation § 1.643(b)-1 Safe Harbor
Under Treas. Reg. § 1.643(b)-1, the IRS formally recognizes state statutory unitrust conversions. A state statute providing for a unitrust payout between 3.0% and 5.0% of the net fair market value of trust assets satisfies the definition of "fiduciary accounting income" for all federal income, estate, and gift tax purposes (including the marital deduction and GST grandfathering protection).
Valuation Smoothing Mechanisms
To protect the income beneficiary from abrupt income swings caused by market volatility, unitrust distributions are typically calculated using a 3-year (12-quarter) rolling average of net asset values.

A trust portfolio generates the following receipts during the calendar year: $18,000 in ordinary cash dividends, $12,000 in municipal bond coupon interest, a 5% stock dividend consisting of 100 shares valued at $10,000, and $65,000 in net capital gains from the sale of common stock. Under default UPAIA/UFIPA rules, what is the total Fiduciary Accounting Income (FAI) distributable to the income beneficiary?
A surviving spouse serves as the sole trustee and sole income beneficiary of an irrevocable QTIP Trust holding $4,000,000 in growth stocks that generate only $20,000 (0.5%) in annual dividends. To increase distributions, the spouse wishes to exercise the statutory Power to Adjust under UPAIA § 104 to transfer $140,000 of realized capital gains to income. Why is the spouse legally prohibited from exercising this power?
During the tax year, an irrevocable trust incurs the following expenses: $16,000 in corporate trustee fees, $4,000 in fiduciary tax preparation fees, $6,000 in routine plumbing/repairs on rental property, and $30,000 for a new roof replacement (capital improvement). How should these disbursements be allocated between Income and Principal under UPAIA §§ 501–502?
