A Tool Designed for the Long Game
Among the sophisticated vehicles available to donors who want to balance income needs, tax optimization, and charitable intent, the charitable remainder trust occupies a distinctive position. Unlike an outright gift that transfers assets permanently and immediately, and unlike a bequest that provides no lifetime benefit, the charitable remainder trust allows a donor to contribute appreciated assets, receive a stream of income for life or a term of years, take a current partial charitable deduction, eliminate capital gains on the contributed assets, and ultimately leave the remainder to charity.
When structured correctly for the right donor situation, the CRT creates genuine value for all parties: the donor receives income they might not have generated from the same assets in their portfolio, the capital gains tax that would have accompanied a sale is avoided, a charitable deduction provides immediate tax relief, and the designated charity ultimately receives a meaningful gift. Understanding how this vehicle works—and when it is and is not appropriate—is an essential component of sophisticated philanthropic and financial planning.
The Basic Mechanics
A charitable remainder trust is an irrevocable trust that makes distributions to one or more non-charitable beneficiaries (typically the donor and/or spouse) for a period that ends either at the death of the income beneficiary or at the conclusion of a fixed term not to exceed twenty years. At the trust’s termination, the remaining assets pass to one or more qualified charitable organizations.
The IRS requires that the charitable remainder interest—the present value of what the charity will receive at the trust’s termination—must be at least 10 percent of the initial contribution, calculated using IRS actuarial tables. This constraint ensures that the trust has genuine charitable substance and is not merely a tax-avoidance vehicle dressed in philanthropic language. The 10 percent floor also means that the structure is more favorable for older donors, whose income payments will span a shorter expected period, leaving a larger remainder for charity.
Two primary variants of the CRT exist, distinguished by how the income stream is calculated.
The Charitable Remainder Annuity Trust (CRAT) pays a fixed dollar amount each year—at least 5 percent of the initial contribution—for the duration of the trust. The payment does not change as the trust’s value fluctuates. This predictability suits donors who want fixed, reliable income. However, the CRAT cannot receive additional contributions after its establishment, and if the trust’s assets are depleted by distributions and poor investment returns, payments cease.
The Charitable Remainder Unitrust (CRUT) pays a fixed percentage of the trust’s assets as revalued each year—again, at least 5 percent. Because the payment is tied to current asset value, it fluctuates with investment performance. In strong markets, distributions increase; in weak markets, they decrease. The CRUT can receive additional contributions and thus functions as a more flexible vehicle for ongoing planning.
Within the CRUT category, several further variants exist. The Net Income CRUT (NICRUT) pays the lesser of the unitrust amount or the trust’s net income—useful when the trust holds illiquid assets. The Net Income with Makeup CRUT (NIMCRUT) allows deficient years to be made up in future years when income exceeds the unitrust amount. The Flip CRUT converts from a net income trust to a standard unitrust upon a specified triggering event, such as the sale of an illiquid asset—particularly useful when funding the trust with real estate or private business interests.
The Capital Gains Advantage
The most powerful financial feature of the charitable remainder trust, for donors holding highly appreciated assets, is its treatment of capital gains. When a donor contributes appreciated assets directly to a CRT, no capital gains tax is owed at the time of the contribution. The trust is a tax-exempt entity and pays no capital gains tax when it liquidates contributed assets and reinvests the proceeds. The full pre-tax value of the contributed assets is available to generate income for the donor—unlike a direct sale, where capital gains tax immediately reduces the investable base.
The tax benefit is not a permanent avoidance of capital gains, however. It is a deferral and conversion. As the trust makes distributions to the donor, a four-tier tax system applies: ordinary income is distributed first, then capital gains, then tax-exempt income, then return of principal. Distributions characterized as capital gains are taxed to the donor at capital gains rates when received. The timing and character of distributions depend on the trust’s investment strategy and income generation.
For donors holding very highly appreciated assets—a stock with minimal cost basis, a business interest, or appreciated real estate—the CRT allows the full pre-tax value to be invested at trust establishment, generating a larger income stream than would result from investing the after-tax proceeds of a direct sale. Over the life of the trust, this compounding advantage can be substantial.
The Charitable Deduction
At the time of the CRT’s establishment, the donor takes a charitable deduction equal to the present value of the charitable remainder interest—what the charity is expected to receive at the trust’s termination, calculated using IRS actuarial tables based on the donor’s age (for life income trusts), the IRS Section 7520 rate in effect at the trust’s establishment, and the trust’s payout rate.
The deduction is taken in the year of contribution, subject to applicable AGI limitations (60 percent for cash, 30 percent for appreciated property contributed to most CRTs, with five-year carryforward). Because the deduction represents only the charitable remainder portion of the contribution, it is typically significantly less than the total contribution—for a 40-year-old donor at a moderate payout rate, the charitable deduction might represent 30 to 40 percent of the contributed value.
The Section 7520 rate, which the IRS sets monthly based on prevailing interest rates, significantly affects the calculation. In higher rate environments, the present value of the charitable remainder is higher (future amounts are discounted at a higher rate), producing a larger deduction but a less favorable income stream. In lower rate environments, the unitrust structure generally performs better from the donor’s perspective. Working with an advisor who can model the CRT mechanics across different rate scenarios is essential for optimal timing of trust establishment.
Funding the Trust: Asset Selection
The choice of assets to contribute to a CRT significantly affects its performance and the donor’s overall tax outcome.
Appreciated publicly traded securities are the most common CRT funding asset. The capital gains avoidance benefit is clear, the liquidation of contributed shares is straightforward, and the proceeds can be reinvested immediately in a diversified portfolio designed to generate the trust’s income stream.
Appreciated real estate is a powerful CRT funding asset when the property is unencumbered (mortgaged property creates debt-financed income complications) and the donor wants to convert an illiquid, low-yielding investment into a reliable income stream. The Flip CRUT is typically the appropriate vehicle for real estate contributions, converting to a standard unitrust after the property is sold. Appraisal requirements for real estate contributions mirror those for direct charitable gifts.
Private company equity can be contributed to a CRT prior to an anticipated sale, similar to the strategy used with donor advised funds. The timing requirements are more demanding—the contribution must be made before any binding sale agreement—and the use of a Flip CRUT is typically required. When structured correctly, the strategy allows the donor to avoid capital gains on appreciated business interests while establishing a reliable income stream from the sale proceeds held within the trust.
Naming the Charitable Beneficiary
The designated charitable remainderman of a CRT can be a public charity, a private foundation, or a donor advised fund. Designating a donor advised fund as the remainderman provides maximum flexibility: the assets arrive at the DAF at the trust’s termination, and the donor (or successor advisors) then recommend grants to specific organizations according to priorities that may evolve over the intervening decades.
This flexibility is particularly valuable for younger donors who establish CRTs before their philanthropic priorities are fully developed. The DAF remainderman allows the charitable capital to be deployed strategically at termination rather than being irrevocably committed to a specific organization at trust establishment.
When the CRT Is and Is Not Appropriate
The CRT is most appropriate for donors who have significant appreciated assets they would like to liquidate and redeploy into income-generating investments, who have genuine charitable intent and are comfortable making an irrevocable charitable commitment, who are in high enough income tax brackets to benefit substantially from the charitable deduction and capital gains avoidance, and who want reliable income for life or a defined term.
The vehicle is less appropriate for donors whose primary objective is maximizing the inheritance available to heirs—since the charitable remainder reduces what passes to family—or for donors who may need to reclaim their capital in an emergency. The irrevocability of the CRT is a real constraint that must be understood and accepted.
For the right donor situation, however, few planning vehicles match the CRT’s ability to simultaneously address income planning, capital gains management, estate planning, and philanthropic objectives within a single integrated structure. The sophistication of the tool reflects the sophistication of the planning challenge it is designed to solve.
