Charitable Remainder Trust Explained

A charitable remainder trust (CRT) is a legal arrangement where you fund an irrevocable trust with appreciated assets, receive income during your lifetime (or a set term), claim an upfront charitable deduction on your taxes, and arrange for the remaining balance to pass to a charity at the end. It solves a common planning problem: how to support a cause you care about while reducing your tax bill and locking in income from an asset you no longer need to sell outright.

Why Charitable Remainder Trusts Exist

The typical scenario: you own a concentrated stock position, commercial property, or other asset that has appreciated far beyond your cost basis. You’d like to diversify or relocate the capital, but selling triggers a large capital gains tax. Equally, you want to support a charitable cause during your lifetime and afterward. A CRT lets you do both without paying full tax on the sale.

By placing the asset into a trust and authorizing the trustee to sell it, the sale occurs inside the trust, where capital gains tax is either deferred or paid at trust rates. You receive a stream of income based on the trust’s distributions, and the IRS credits you with an immediate charitable deduction for the present value of what will eventually pass to the charity.

How a Charitable Remainder Trust Works

You fund the CRT with an appreciated asset—say, shares worth $500,000 that cost you $100,000. The trustee sells the shares. Normally, you’d owe capital gains tax on the $400,000 gain; inside the trust, the gain is taxed to the trust, typically at higher rates, but spread over time or deferred as the trust reinvests. You then receive a fixed stream of income each year, structured as either:

• Charitable Remainder Annuity Trust (CRAT): You receive a fixed dollar amount annually, regardless of trust performance.
• Charitable Remainder Unitrust (CRUT): You receive a fixed percentage of the trust’s value, recalculated each year, so payments fluctuate with market value.

The remainder—whatever principal is left when you pass away—goes to your chosen charity or charities. IRS rules require the charity to receive at least 10% of the initial contribution and the income distribution to be no less than 5% annually; the maximum is 50% for a CRAT or CRUT, though practical upper bounds are lower.

The Immediate Tax Deduction

On the date you fund the trust, you claim a charitable deduction for the present value of the charity’s future interest. The IRS calculates this using IRS Section 7520 rates (based on long-term interest rates at the time of funding). If you fund a CRT with $500,000 and the charity will eventually receive, say, $250,000 in today’s dollars (after 20 years of payouts), your deduction is approximately that $250,000. Importantly, this deduction occurs in the year of funding and is not limited by the usual charitable contribution caps if you choose to carry it forward.

The deduction is valuable if you have high income or significant gains in the year you fund the trust. However, the deduction is a present value calculation—you’re not deducting $500,000; you’re deducting the remainder value, which depends on your life expectancy, the payout rate, and interest rates.

Income Taxation of Distributions

The distributions you receive each year are taxed in layers, depending on the trust’s composition:

1. Ordinary income (interest, dividends, rent) distributes first and is taxed at ordinary income rates.
2. Capital gains (from the sale of the appreciated asset) distribute next and are taxed at capital gains rates.
3. Return of principal (non-taxable basis) distributes last.

This “stacking” rule means your early distributions may be taxed at ordinary income rates, but over time, as the trust’s interest and dividend income is exhausted, distributions shift toward the capital gains layer and eventually the non-taxable basis. The exact order matters for your tax planning; a CRT with a highly appreciated asset and low yield will generate long-term capital gains rates over many years.

Control and Irreversibility

Once funded, a CRT is irrevocable. You cannot take the money back, change the beneficiaries, or dissolve it. The trustee controls the investments and distributions according to the trust document. This finality appeals to some donors (strong commitment to the cause) and deters others (loss of flexibility). Some donors serve as trustee or co-trustee, allowing them to direct investment policy while a professional trustee or a bank handles administration.

Because the CRT is irrevocable and you’ve given up dominion and control of the assets, they leave your estate entirely. This provides an additional benefit: the trust assets do not pass through your probate estate, avoiding delays and probate costs, and they may be outside the reach of estate tax if structured carefully.

Variation: The Flip CRUT

A variation called the Flip CRUT starts as an annuity trust (fixed payout, regardless of market value) but automatically “flips” to a unitrust (percentage payout) after a triggering event, often a sale of the appreciated asset. This combines the stability of early, fixed payments with the flexibility of later adjustments. The flip typically occurs once the appreciated asset has been sold and reinvested, locking in a guaranteed income while allowing later participation in market growth.

Strategic Considerations

A CRT works best if you have a long life expectancy (so the income stream is valuable), hold a highly appreciated but low-yielding asset, are charitably inclined, and are in a high tax bracket. The upfront deduction is most valuable in years of peak income or large gains.

Conversely, if you want to leave the bulk of your wealth to family, a CRT redirects principal away from heirs to a charity. If you expect the asset to grow substantially, locking in a percentage distribution (CRUT) may leave you with inadequate income later. If interest rates are low, the IRS Section 7520 rate used to calculate your deduction shrinks, reducing the tax benefit.

Charitable Intent and Legacy

The strategic benefit is real, but the structure works only if the charity is genuinely chosen. The IRS scrutinizes CRTs to ensure the donor isn’t using them primarily for tax avoidance without legitimate charitable purpose. Courts have upheld CRTs and CRUTs where donors named real charities and documented genuine intent; claims that a “private” cause or entity qualifies as a charity may face challenge.
