Accounting for Charitable Remainder Trusts: Four-Tier Income and Filing

Accounting for charitable remainder trusts turns on one hard rule: the trust itself pays no income tax, but every dollar it distributes to a non-charitable beneficiary must be characterized through a strict four-tier ordering system that tracks the character of income the trust has earned across its entire lifetime. The trustee’s job is to set up each asset correctly at contribution, run the tier records accurately every year, calculate the required distribution under the trust’s payout formula, and reconcile everything on Form 5227 with matching K-1s. Get any piece of that wrong and the errors compound quickly: misstated beneficiary income, broken year-over-year continuity, and in some cases excise taxes that can wipe out an entire year of trust earnings.

Recording the Initial Contribution

Every asset a donor transfers into a CRT needs two numbers on the trust’s books: its fair market value on the date of contribution, and the donor’s adjusted cost basis. The fair market value becomes the book value and drives the initial distribution math. The basis carries over to the trust and is what the trustee uses to calculate capital gain or loss when the asset is later sold.

A donor who contributes publicly traded stock worth $500,000 with a $100,000 cost basis gives the trust a $500,000 asset on the ledger and a $100,000 basis to track separately. When those shares sell, the gain measured against the $100,000 carryover basis is what flows into the capital gains tier.

For real estate, closely held business interests, or any other illiquid holding, the trustee needs a qualified appraisal to establish fair market value at contribution. That appraisal supports the starting book value and backs up the donor’s charitable deduction. Classify every asset by type in the general ledger from day one — that classification is what supports annual revaluations for unitrusts and the proper tier and class categorization when income is earned or gains are realized.

The donor’s charitable income tax deduction is calculated using IRS actuarial tables, and the present value of the future gift to charity must equal at least 10% of the net fair market value of the property placed in trust.¹ The deduction itself belongs on the donor’s return, not the trust’s books, but the trustee should keep a copy of the calculation because it documents the initial asset values everything else builds from.

The Four-Tier Income System

The feature that makes CRT accounting genuinely different from other trust bookkeeping is the mandatory four-tier ordering system. Every distribution to a non-charitable beneficiary must be characterized under this system, and it runs as a strict priority. The trust must exhaust all available income in Tier 1 before a single dollar can be drawn from Tier 2, and so on down.¹ The most heavily taxed income comes out first.

Tier 1 is ordinary income: interest, rental income, business income, and dividends both qualified and non-qualified. This tier accumulates over the trust’s life. Current-year ordinary income adds to any undistributed ordinary income from prior years.
Tier 2 is capital gains, both short-term and long-term. The trust tracks cumulative net capital gains across its whole existence, netting current-year gains against any carried-forward losses.
Tier 3 is other income, primarily tax-exempt income such as municipal bond interest. Distributions from this tier are generally received tax-free at the federal level.
Tier 4 is return of corpus. Distributions reach this tier only after the first three are fully exhausted, and they’re not taxable to the beneficiary.

Classes Within Each Tier

This is where most accounting mistakes happen. The four broad tiers aren’t the whole picture. Inside the ordinary income and capital gains tiers, income must be broken down further into separate classes based on the federal tax rate that applies to each type.² Within a tier, distributions come from the highest-taxed class first, then the next highest.

The ordinary income tier needs at least two classes: qualified dividend income taxed at preferential capital gains rates, and everything else taxed at the beneficiary’s marginal rate. The capital gains tier calls for separate classes for short-term gains, 28-percent-rate gains from collectibles, unrecaptured Section 1250 gains from depreciated real property, and all other long-term gains.³

A CRT holding a diversified portfolio can easily be carrying six or more sub-accounts at once across the tiers. Each year’s income drops into the correct class, and the cumulative balance of every class carries forward. Classes taxed at the same rate can be combined if a rate change is permanent; if the change is temporary, they stay separate.² Trying to run this on paper is a losing proposition. Spreadsheets or specialized trust accounting software are practically mandatory.

Net Investment Income Tax

The CRT itself is exempt from the 3.8% net investment income tax under Section 1411 because it’s already exempt from Subtitle A income taxes.⁴ The beneficiary isn’t exempt. Distributions consisting of net investment income are subject to the 3.8% surtax in the beneficiary’s hands, on top of regular income tax at the applicable tier and class rate.

The trustee has to categorize net investment income using the same tier and class framework rather than tracking it as one lump. That means identifying which portions of each class within each tier constitute net investment income and reporting those amounts on the beneficiary’s K-1 so the beneficiary can compute their own Section 1411 liability.

Calculating the Annual Distribution

How much the trust pays out each year depends on whether it’s a charitable remainder annuity trust or a charitable remainder unitrust. The two calculate distributions differently, and each generates its own accounting demands.

Annuity Trusts

A CRAT pays a fixed dollar amount every year, locked in at inception. That amount must be at least 5% but no more than 50% of the initial net fair market value of the property placed in trust.¹ A $1 million CRAT with a 6% payout rate distributes $60,000 every year, regardless of how the portfolio performs. No additional contributions are permitted after the initial funding.

At inception, there must be less than a 5% probability that annuity payments will exhaust the trust before the term ends.⁵ Failing that probability of exhaustion test can cost the donor the charitable deduction entirely, which is a design-stage concern rather than an ongoing accounting one.

Unitrusts

A CRUT pays a fixed percentage, also between 5% and 50%, of the trust’s net asset value as revalued each year.¹ A 5% CRUT holding $1.2 million on its valuation date pays $60,000 that year. If assets grow to $1.4 million by the next valuation date, the payment rises to $70,000.

Annual revaluation is the critical accounting event for a CRUT. The trust document names a specific valuation date, kept consistent from year to year and typically near the start of the calendar year. Every asset must be valued at fair market value on that date. Publicly traded securities are simple. Real estate, closely held businesses, and other illiquid holdings require fresh appraisals. The methodology has to be documented and applied consistently, because the IRS will compare year-over-year valuations on Form 5227 for reasonableness.

Running the Four-Tier Draw-Down

Once the required distribution amount is calculated, the four-tier system determines its character for tax purposes. If the required distribution is $20,000 and the trust has $15,000 of accumulated ordinary income in Tier 1 and $10,000 of capital gains in Tier 2, the first $15,000 comes from Tier 1 and the remaining $5,000 from Tier 2. The beneficiary reports $15,000 as ordinary income and $5,000 as capital gain, broken out further by class within each tier.

Internally, the entry reduces the cash account by the payment amount and reduces the corresponding tier and class balances by the same amounts. Any income earned during the year in excess of the required distribution stays in its tier and class and carries forward.

NIMCRUTs and Flip Provisions

A Net Income with Makeup CRUT (NIMCRUT) pays the lesser of the stated unitrust percentage or the trust’s actual net income for the year. This structure fits trusts holding illiquid assets like real estate or pre-IPO stock that don’t produce much current income.

In years when net income falls short of the unitrust percentage, the shortfall accumulates in a makeup account. The trustee has to track this cumulative deficiency on a separate subsidiary ledger. When the trust later earns more than the unitrust percentage in a year, the excess pays down the makeup account. Those makeup payments run through the same four-tier system as regular distributions.

Flip CRUTs

A flip CRUT starts as a NIMCRUT and converts permanently to a standard unitrust after a specified triggering event. The trigger has to be an objective occurrence not within the discretion or control of the trustee or any other person.⁶ Permissible triggers include the sale of unmarketable assets such as closely held stock, or a life event like marriage, divorce, death, or the birth of a child.

The conversion takes effect on January 1 of the year following the triggering event.⁶ From that date forward, the trust pays the full unitrust percentage regardless of actual net income, and the makeup account is eliminated. The trustee needs to document the triggering event and the conversion date clearly, because the switch changes how every subsequent distribution is calculated.

Traps That Can Blow Up the Accounting

The 100% Excise Tax on UBTI

A CRT’s tax exemption comes with a severe backstop. If the trust has any unrelated business taxable income in a given year, it owes an excise tax equal to 100% of that income.¹ Not part of it. All of it.

Common UBTI sources include income from debt-financed property such as leveraged real estate, income from an active trade or business, and certain partnership allocations. The trustee has to screen every investment and income stream to keep UBTI from appearing on the books at all. A real estate investment that would be routine in a taxable trust can trigger a dollar-for-dollar tax hit inside a CRT.

Self-Dealing

CRTs are subject to the same self-dealing rules that govern private foundations. Under IRC 4947, split-interest trusts must follow the prohibited transaction rules of IRC 4941, which bar virtually all financial dealings between the trust and disqualified persons — a group that includes the donor, the trustee, family members, and entities they control.⁷

Prohibited transactions include selling or leasing property between the trust and a disqualified person, lending money in either direction, providing goods or services, and transferring trust income or assets for the benefit of a disqualified person. The initial excise tax on the self-dealer is 10% of the amount involved for each year the violation persists, plus a 5% tax on any trust manager who knowingly participated. If the transaction isn’t corrected within the taxable period, the additional tax jumps to 200% of the amount involved.⁸

For accounting purposes, this means documenting every counterparty on every transaction, including routine expenses. Paying a family member to manage trust property, or using trust funds to improve real estate the donor still occupies, can both cross the line.

Tax and Information Reporting

Annual reporting centers on IRS Form 5227, the Split-Interest Trust Information Return. Every CRT files this form annually, even in years with no taxable income.⁹ The form captures fair market value of all assets, income earned by category and class, distributions made, and the running balance of every tier.

The trustee also prepares a Schedule K-1 (Form 5227) for every non-charitable beneficiary who received a distribution during the year. The K-1 reports the character and amount of income the beneficiary must pick up on their personal return. Those amounts come directly from the four-tier draw-down. A beneficiary who received $30,000 consisting of $10,000 of ordinary income and $20,000 of long-term capital gain gets a K-1 reflecting each amount separately, broken down further by class when multiple rates apply. Total K-1 distributions must match total distributions on Form 5227.

Deadlines and Penalties

Form 5227 is due April 15 of the year after the tax year. An automatic extension is available by filing Form 8868.¹⁰

Late or incomplete filing penalties are tiered by trust size. For most trusts the penalty is $25 per day up to a maximum of $13,000 per return. For trusts with gross income exceeding $327,000, it’s $130 per day up to $65,000.¹¹ Those figures come from the 2025 instructions and may adjust in later years. If the person responsible for filing knowingly fails to do so, the penalty applies to them personally in addition to any penalty on the trust.¹²

Form 8282 for Sales of Donated Property

If the trust sells, exchanges, or otherwise disposes of non-cash donated property within three years of receiving it, and the property was valued at more than $5,000 on the donor’s Form 8283, the trust must file Form 8282 (Donee Information Return) within 125 days of the disposition.¹³ The form tells the IRS the sale price so it can check whether the donor’s original deduction was reasonable. The penalty for failing to file is generally $50 per form.¹⁴

Year-Over-Year Continuity

The closing balance of each tier and class on the current year’s Form 5227 must exactly match the opening balance on the following year’s form. This continuity check is one of the first things the IRS looks at, and a mismatch signals either a math error or mischaracterized income. It’s a straightforward reconciliation, but only if the underlying tier records have been kept accurately all year.

Accounting at Termination

A CRT terminates when the last income beneficiary dies or the specified term (up to 20 years) expires.¹ Distributions to the income beneficiary stop, and the trustee prepares a final accounting of assets and liabilities.

Assets that can’t be transferred in-kind to the designated charity efficiently are liquidated. Outstanding debts and administrative expenses are settled. The net fair market value of the final charitable distribution is confirmed. The transfer of remaining assets to the charity is generally not a taxable event because the recipient is tax-exempt.

A final Form 5227 marked as a final return is filed. Any income still sitting in the tiers at termination is reported on that return. If distributions went to the beneficiary during the trust’s final tax year, the trustee issues final K-1s reflecting those distributions through the four-tier system. Trust records should be archived for at least the applicable statute of limitations after the final return, which is generally three years but extends to six years if the IRS alleges a substantial understatement of income.
