How Does A CRUT Work? | The Most Flexible Way To Give

A CRUT pays you variable income for life or up to 20 years, then donates the remaining assets to a charity you choose.

Most people assume a large charitable donation simply means writing a check or signing over an asset and taking a deduction. A Charitable Remainder Unitrust (CRUT) offers a fundamentally different trade-off.

You can donate highly appreciated assets—like stock or real estate—into an irrevocable trust. The trust is tax-exempt, so it can sell those assets without triggering an immediate capital gains event. In return, it pays you a variable income stream for life or up to 20 years. The remainder then passes to the qualified charity you chose.

How A CRUT Actually Works

The mechanics of a CRUT are built around annual revaluation. Each year, the trust calculates its fair market value on a specific date. The beneficiary receives a fixed percentage of that revalued amount. This percentage must fall between 5% and 50% of the trust’s annual value per IRS rules.

If the trust’s investments perform well, your payout grows. If the value drops, your payout drops accordingly. This variable structure allows the trust to hold growth-oriented assets that might be too volatile inside a fixed annuity trust.

At the end of the payment term—either the death of the beneficiary or a defined period of up to 20 years—the remaining assets pass to one or more qualified charitable organizations. The trust is irrevocable, meaning the terms cannot be changed once established.

Why The Variable Payout Matters

A fixed-income stream is comfortable until inflation erodes its purchasing power. A CRUT addresses this directly because your income isn’t fixed at a dollar amount. It adjusts with the trust’s market value, acting as a natural hedge. This is often the primary reason donors choose a CRUT over a Charitable Remainder Annuity Trust (CRAT).

• Capital gains avoidance: The trust is tax-exempt, so selling highly appreciated assets inside the trust generally avoids triggering a capital gains event at the time of sale.
• Variable income stream: Your payout is recalculated annually. If the trust’s assets appreciate, your income can increase, which offers some protection against inflation.
• Additional contributions allowed: You can add more assets to a CRUT over time, which is a flexibility that a CRAT does not offer.
• Estate planning value: The trust can provide income for a spouse or other beneficiary for life, then pass the remainder cleanly to a chosen charity.
• Potential tax deduction: You may be eligible for an income tax deduction in the year you fund the trust, based on the present value of the charity’s remainder interest.

Each of these features comes with specific IRS requirements. The payout rate you choose has a direct impact on both your income stream and the value of your charitable deduction.

CRUT Vs. CRAT — Key Structural Differences

The most common point of confusion is the difference between a CRUT and a CRAT. Both are irrevocable, tax-exempt trusts that provide income to a non-charitable beneficiary with a charitable remainder. The payout mechanism is the primary difference. Per the IRS’s official charitable remainder unitrust definition, the CRUT’s revaluation structure is what makes it more flexible in a growth-oriented portfolio.

The right choice depends on whether you prioritize predictable income or the potential for growth. A CRUT is often preferred by donors who want to keep the option of adding more assets later and who want a trust that can benefit from market appreciation over time.

Four Steps To Setting Up A CRUT

Setting up a CRUT requires careful coordination with a qualified estate planning attorney. The trust is irrevocable, so every detail must be accurate before the documents are signed. Here are the core decisions you will need to make.

1. Choose your assets carefully: The CRUT works best with highly appreciated, low-basis assets like real estate, concentrated stock positions, or private business interests. The trust is tax-exempt, so it can sell these assets without a tax bill.
2. Select your payout rate: You must choose a rate between 5% and 50%. A higher rate offers more immediate income but reduces both the tax deduction and the amount left for the charity. A lower rate allows the trust to grow faster and provides a larger deduction.
3. Name your charitable beneficiaries: The charity must be a qualified U.S. organization. The IRS requires the remainder interest to be at least 10% of the initial fair market value of the assets contributed to the trust. This is known as the 10% remainder test.
4. Decide who serves as trustee: You can serve as your own trustee, which gives you control over the investment of the trust assets. Many donors choose a corporate trustee like a major financial institution to handle the administrative complexity.
5. Fund the trust irrevocably: Once the trust is funded, it cannot be changed. This means you must be absolutely certain about your beneficiaries, payout rate, and charitable intent before transferring assets.

Each of these steps has tax implications that require coordination with a CPA or tax specialist. Mistakes in the trust document or funding process can jeopardize the tax-exempt status of the trust.

Tax Benefits And The 10% Rule

The tax advantages of a CRUT are substantial but governed by strict IRS rules. When you fund the trust, you may be eligible for an income tax deduction. This deduction is calculated based on the present value of the remainder interest that will eventually go to charity. The calculation depends on the payout rate you choose, the term of the trust, and the applicable federal rate. For a deeper look at the variables, Georgetown’s CRUT tax deduction guide walks through a sample calculation that shows how the fair market value and payout rate interact.

The trust’s tax-exempt status is another critical benefit. The trust pays no tax on its investment earnings or on the capital gains from the sale of contributed assets. This allows the trust to reinvest fully without a tax drag, which can compound over the term of the trust.

The IRS also requires the trust to distribute income to at least one noncharitable beneficiary for the term of the trust. The payments cannot be simply accumulated indefinitely.

The Bottom Line

A CRUT is a specific tool for a specific financial situation. It works best when you have a highly appreciated asset you want to sell, a desire for a variable income stream, and a charitable cause you want to support. The trust is irrevocable, so there is no changing the terms once they are signed.

The exact numbers—the best payout rate for your age, the actual tax deduction you can claim, and whether the 10% remainder test is met—depend entirely on your personal financial situation, the type of assets you hold, and your state of residence. An estate planning attorney who specializes in charitable trusts or a CPA with experience in planned giving can model the outcomes for you and help determine if a CRUT aligns with your broader financial and philanthropic goals.
