Charitable Remainder Trusts: CRUT vs. CRAT — Powerful Tax Strategies for Appreciated Assets
Most people think of charitable giving as something you do after the tax planning is done. Charitable Remainder Trusts turn that assumption upside down. For business owners, real estate investors, and anyone sitting on a large capital gain, a properly structured CRT can defer capital gains taxes, generate an immediate charitable deduction, provide lifetime income, and reduce estate tax exposure — all at once. This is one of the most powerful and underutilized tools in advanced estate planning.
What Is a Charitable Remainder Trust?
A Charitable Remainder Trust (CRT) is an irrevocable trust authorized under Internal Revenue Code § 664 that works in three stages: (1) you transfer appreciated assets into the trust, (2) you — or other named beneficiaries — receive an income stream for a term of years or for life, and (3) at the end of the trust term, the remaining assets pass to one or more qualified charitable organizations.
The defining feature of the CRT is what happens in the middle: the trust, not you, sells the appreciated assets. Because a properly structured CRT is a tax-exempt entity, the sale inside the trust does not immediately trigger capital gains tax. Instead, taxes are spread over time as income is distributed to you — dramatically reducing the immediate tax burden that would result from a direct sale.
A CRT is not a pure charitable gift. It is a hybrid instrument designed to accomplish multiple goals simultaneously: tax planning, retirement income, and charitable giving in a single integrated structure. The income you receive can be for your lifetime, the joint lifetimes of you and a spouse, or a fixed term of up to 20 years.
The Four Core Tax Advantages of a CRT
When you transfer appreciated assets to a CRT before a sale, the trust sells the assets without immediately recognizing capital gains. Tax is deferred and spread over time as income distributions are made, dramatically reducing the immediate tax cost of liquidating a concentrated position.
When you fund a CRT, you receive a current-year charitable deduction equal to the present value of the remainder interest that will ultimately pass to charity. The IRS calculates this using your life expectancy, the payout rate, and the applicable federal rate (AFR). For high earners, this deduction alone can generate substantial tax savings.
Assets transferred to a CRT are removed from your taxable estate. The remainder ultimately passes to charity — not to your heirs — which means those assets are not subject to federal estate tax. This can be a meaningful benefit for estates near or above the federal exemption threshold, which is currently scheduled to decrease substantially when TCJA sunsets in 2026.
A CRT is not purely altruistic. It is specifically designed to pay you — or other named income beneficiaries — a regular income stream for life or a term of years. This makes CRTs a particularly powerful tool for retirement income planning when combined with the capital gains and estate tax benefits.
Charitable Remainder Trusts are creatures of federal tax law. To qualify as a CRT and receive the associated tax benefits, the trust must comply with the specific requirements of IRC § 664, including minimum and maximum payout rates, a minimum remainder value test (at least 10% of the initial funding amount must pass to charity), and the requirement that the charitable remainder beneficiary be a § 501(c)(3) organization or other qualified charity.
Failure to meet these requirements can disqualify the trust and eliminate all tax benefits — making competent legal and tax counsel essential before implementation.
CRUT vs. CRAT: Understanding the Key Difference
Both CRUTs and CRATs are charitable remainder trusts that offer the same core tax benefits. The critical difference is how your income payment is calculated each year. That single distinction drives almost every other trade-off between the two structures.
- Payment basis: Fixed percentage of the trust’s value, revalued annually
- Payment amount: Fluctuates with investment performance — rises in good years, falls in down years
- Payout rate: Must be between 5% and 50% per year
- Additional contributions: Allowed after initial funding
- Flexibility: Higher — can serve as ongoing charitable planning vehicle
- Inflation protection: Yes — payments grow if the trust grows
- Variants: Standard CRUT, Net Income CRUT (NICRUT), Net Income with Makeup CRUT (NIMCRUT), Flip CRUT
- Payment basis: Fixed dollar amount determined at funding — never changes
- Payment amount: Same every year regardless of investment performance
- Payout rate: Must be between 5% and 50% of initial value
- Additional contributions: Not allowed — single-funding only
- Flexibility: Lower — simpler administration, no revaluation required
- Inflation protection: No — payment is fixed in nominal dollars
- Variants: Standard CRAT only (no special variants)
Side-by-Side Comparison

The Most Powerful Use Case: Selling a Highly Appreciated Asset
The single most compelling application of a charitable remainder trust is the sale of a highly appreciated asset — real estate held for decades, a concentrated stock position, or a closely held business. The tax math is dramatic.
The situation: Margaret purchased a commercial property in 1998 for $180,000. Today it is worth $1,400,000. She has taken substantial depreciation over the years. She wants to sell, retire, and live off investment income.
Direct sale — the costly path:
Using a CRUT — the alternative path: Margaret transfers the property to a CRUT before the sale. The trust sells the property for $1,400,000 with no immediate capital gains recognition. The full $1,400,000 is available to reinvest inside the trust. At a 6% annual unitrust payout, Margaret receives approximately $84,000 per year in income. She also receives an immediate charitable deduction — calculated based on her age, the payout rate, and the current AFR — that reduces her current income taxes further. The income she receives each year is taxed as it is distributed, but spread over many years at potentially lower rates.
The difference: Instead of $995,500 generating income after tax, the full $1,400,000 works for Margaret. At a 6% return, the after-tax sale puts her at roughly $59,700/year in income. The CRUT generates $84,000/year — roughly 40% more annual income on the same asset — plus the charitable deduction, plus estate tax reduction on the entire $1,400,000.
Note: This example is illustrative. Actual results depend on Margaret’s basis, depreciation history, tax rates, applicable federal rates, life expectancy, and trust investment performance. A qualified CPA and estate planning attorney must run the actual analysis.
CRT Variants: The NIMCRUT and the Flip CRUT
The CRUT structure is flexible enough to have spawned several useful variants, each addressing specific planning needs:
- Net Income CRUT (NICRUT) — pays the lesser of the stated percentage or the actual trust income for that year. Useful when the trust holds illiquid assets that don’t generate regular cash income. The trust pays only what it actually earns, protecting the principal when income is low.
- Net Income with Makeup CRUT (NIMCRUT) — like the NICRUT, but with a “makeup account” that tracks shortfalls in years when actual income falls below the stated percentage. In future years when income exceeds the stated rate, the excess fills in the makeup account — allowing deferred income to be paid in higher-income years or at retirement. A powerful pre-retirement income-deferral tool. Our complete guide to NIMCRUT planning covers this in depth.
- Flip CRUT — begins as a NICRUT or NIMCRUT and “flips” to a standard percentage-of-value CRUT upon a triggering event (sale of an illiquid asset, retirement date, reaching a certain age). Ideal for funding with real estate or a closely held business — the trust holds the asset, sells it, and then flips to standard CRUT distributions once proceeds are liquid.
Coordinating a CRT With Your Broader Estate Plan
A charitable remainder trust rarely makes sense in isolation. It is typically one component of a coordinated estate plan designed to balance tax reduction, family wealth transfer, retirement income, and charitable goals simultaneously.
Wealth Replacement: Pairing a CRT With Life Insurance
The most common CRT coordination strategy is the wealth replacement trust: because the charitable remainder of the CRT will ultimately pass to charity rather than your heirs, some clients use a portion of the income stream — and/or the charitable deduction tax savings — to fund a life insurance policy in an irrevocable life insurance trust (ILIT). The life insurance death benefit replaces, for the heirs, the wealth that passes to charity. The family gets the equivalent of an inheritance. Charity gets the remainder. The donor gets lifetime income and substantial tax savings. Our ILIT guide explains how this coordination works.
CRTs and Business Sale Planning
Business owners planning an exit often face enormous capital gains exposure on the sale of a closely held company. A CRT funded with business interests before the sale can defer or spread the gain, provide retirement income, generate a charitable deduction, and remove the business value from the estate — all in a single structure. The Flip CRUT is commonly used here: the trust holds the business interest, the business is sold inside the trust, and the trust flips to standard CRUT distributions from the liquid proceeds. Coordination with a SLAT or other estate-freezing vehicle is also common.
CRTs and the TCJA Sunset
The federal estate tax exemption — currently $13.61 million per individual — is scheduled to drop to approximately $7 million (adjusted for inflation) when the Tax Cuts and Jobs Act provisions sunset at the end of 2025. For individuals whose estates may cross the post-sunset threshold, removing appreciated assets from the taxable estate through a CRT — combined with other planning strategies — is increasingly relevant. The window to plan under current law is narrowing.
Important Limitations and Considerations
Irrevocability: Once assets are transferred into a CRT, they cannot be taken back. The charitable remainder is a firm commitment. This is not a tool to use impulsively or without careful analysis of your long-term financial picture.
You must actually want to benefit charity: A minimum of 10% of the initial trust value (under IRC § 664) must pass to a qualified charity at the end of the trust term. If philanthropic intent is absent, other tax strategies may be more appropriate.
Administrative requirements: CRTs must file an annual information return (Form 5227) with the IRS, maintain separate accounting for the four-tier income system that governs how distributions are taxed, and comply with ongoing regulatory requirements. Professional trust administration is typically required.
Payout rate selection is critical: Too high a payout rate — particularly for a CRAT — can result in trust exhaustion before the income term ends, or failure of the 10% remainder test at funding. The IRS will not approve a CRAT that fails the remainder test at inception. Both payout rate and expected return must be modeled carefully.
Who Should Seriously Consider a CRT?
- You own highly appreciated real estate — investment property, commercial real estate, or farmland with a low basis and large embedded capital gain
- You hold a concentrated, low-basis stock position — founder stock, long-held employer shares, or inherited stock with significant unrealized gain
- You are planning a business sale — closely held business or partnership interest with substantial embedded gain
- You want retirement income — need a reliable income stream and want to convert an illiquid or volatile asset into cash flow without triggering the full tax immediately
- You have philanthropic intent — genuinely want to benefit one or more qualified charitable organizations at the end of the trust term
- You face estate tax exposure — your estate is near or above the current exemption, or concerned about post-TCJA sunset exposure
- You are a high earner in a high tax year — the charitable deduction from funding a CRT can offset significant ordinary income in the year of funding
CRTs Are Not for Everyone: When Other Tools May Be Better
A charitable remainder trust is a sophisticated, irrevocable, long-term commitment. For clients whose primary goals do not include charitable giving, or whose situations call for greater flexibility or family-wealth preservation, other strategies may be more appropriate:
- Installment sale — spreads capital gains recognition over multiple years without requiring a charitable commitment. Keeps proceeds in the family.
- Opportunity Zone investment — defers and potentially reduces capital gains by reinvesting proceeds in a Qualified Opportunity Fund within 180 days of sale.
- Charitable Lead Trust (CLT) — the inverse of a CRT. Charity receives income for a term, then remainder passes to heirs. Useful for wealth transfer in low-interest-rate environments.
- SLAT or Irrevocable Gift Trust — transfers appreciation out of the estate while keeping assets available (indirectly) through a spouse. See our SLAT guide.
- Donor-Advised Fund — simplest charitable vehicle for cash or appreciated securities. No income stream, but maximum flexibility and minimal administration.
