Charitable Remainder Trust (CRT) — IRC §664 Practitioner Guide
A Charitable Remainder Trust allows a client to donate highly appreciated assets, avoid immediate capital gains tax, receive an income stream for life or a term of years, and claim a partial charitable deduction — all while ultimately benefiting a charity. Here is how practitioners structure CRTs for maximum client benefit.

How a CRT Works — The Core Mechanics
A Charitable Remainder Trust is an irrevocable split-interest trust. The donor (grantor) transfers appreciated assets to the trust. The trust sells the assets — paying no capital gains tax because the trust is tax-exempt under §664(c). The trust then invests the proceeds and pays an income stream to the donor (or other non-charitable beneficiaries) for life or a term of up to 20 years. At the end of the trust term, the remaining assets pass to a designated charity. The donor receives a charitable deduction in the year of the contribution equal to the present value of the charity's remainder interest.
The key benefit: a client with $1 million of appreciated stock with a $100,000 basis who sells directly pays $135,000 in capital gains tax (15% federal + NIIT + state), leaving $865,000 to invest. The same client who contributes to a CRT has the full $1 million invested, generating a larger income stream over the trust term. The capital gains tax is not eliminated — it is spread over the trust distributions using the §664 four-tier ordering rules — but the deferral and reinvestment of the full pre-tax amount produces a significantly better economic outcome.
CRAT vs. CRUT — Choosing the Right Structure
| Feature | CRAT (Annuity Trust) | CRUT (Unitrust) |
|---|---|---|
| Payout amount | Fixed dollar amount (5%–50% of initial FMV) | Fixed percentage (5%–50%) of trust value, revalued annually |
| Additional contributions | Not permitted after initial funding | Permitted |
| Inflation protection | None — fixed dollar amount erodes with inflation | Yes — payout grows if trust value grows |
| Charitable deduction | Easier to calculate (fixed payout) | More complex (depends on projected growth) |
| Best for | Older donors who want predictable income | Younger donors, growing assets, inflation concern |
| NIMCRUT variant | N/A | Net Income with Makeup CRUT — pays lesser of unitrust amount or net income; makeup provision for future years |
The §664 Four-Tier Ordering Rules — How Distributions Are Taxed
CRT distributions to the income beneficiary are taxed using a four-tier ordering system under §664(b). Distributions are treated as coming from each tier in order until exhausted:
1
Ordinary income. Taxed at ordinary income rates. Includes dividends (qualified and non-qualified), interest, and other ordinary income earned by the trust.
2
Capital gains. Taxed at capital gains rates. Long-term gains are taxed at 0%, 15%, or 20% depending on the beneficiary's income. This is where the appreciated asset's gain is eventually recognized — spread over the distribution period.
3
Other income. Tax-exempt income (e.g., municipal bond interest). Taxed at 0% in the beneficiary's hands.
4
Return of corpus. Tax-free return of the donor's contribution basis. Only reached after all income tiers are exhausted.
The practical implication: if a CRT sells $1 million of appreciated stock with $100,000 basis, the $900,000 of capital gain sits in Tier 2. Every distribution will be treated as capital gain (Tier 2) until the $900,000 is fully distributed. Only after that does the distribution become tax-free return of corpus (Tier 4).
Frequently Asked Questions
Can the donor be the trustee of their own CRT?
Yes. The donor can serve as trustee of their own CRT without disqualifying the trust or triggering grantor trust rules, provided the trustee's powers are limited to those permitted under §664 and the trust instrument. The IRS sample forms in Rev. Proc. 2005-52 and 2005-53 are designed to be used with a donor-trustee. However, many practitioners recommend an independent corporate trustee for large CRTs to avoid self-dealing concerns and to ensure proper administration.
What assets can be contributed to a CRT?
Almost any asset can be contributed to a CRT: publicly traded stock, real estate, closely held business interests, mutual funds, and even cryptocurrency. However, some assets create complications. Real estate with a mortgage may trigger UBTI (unrelated business taxable income) under §514, which can disqualify the CRT. Closely held stock and S-Corp stock have special restrictions. Practitioners should carefully analyze any non-cash contribution before funding a CRT.
How is the charitable deduction calculated?
The charitable deduction equals the present value of the charity's remainder interest, calculated using the IRS §7520 rate (published monthly) and actuarial tables. The deduction is limited to 30% of AGI for contributions of appreciated capital gain property (50% for cash contributions to public charities). Excess deductions carry forward for 5 years. Practitioners should use IRS Publication 1457 (actuarial tables) or a CRT calculator to determine the deduction amount before the client commits to the strategy.
More Tax Planning FAQs
What is the IRS audit risk for this strategy?
The IRS audit rate for individual returns is approximately 0.4% overall, but increases significantly for returns with Schedule C income, large deductions, or specific strategies. Proper documentation is the best defense against an audit. Keep contemporaneous records, maintain written agreements, and ensure all deductions are supported by receipts and business purpose documentation.
How does this strategy interact with the alternative minimum tax (AMT)?
Many tax strategies that reduce regular income tax can trigger or increase AMT liability. Common AMT triggers include: ISO exercises, large state tax deductions, accelerated depreciation, and passive activity losses. Taxpayers should model both regular tax and AMT before implementing aggressive tax strategies to ensure the net benefit is positive.
What is the statute of limitations for IRS assessment of this strategy?
The IRS generally has three years from the later of the return due date or filing date to assess additional tax. If the taxpayer omits more than 25% of gross income, the statute is extended to six years. There is no statute of limitations for fraudulent returns or failure to file. Taxpayers should retain tax records for at least seven years to cover the extended statute of limitations.
How should this strategy be documented to withstand IRS scrutiny?
Documentation is the cornerstone of any tax strategy. Maintain contemporaneous records (created at the time of the transaction), written agreements, business purpose statements, and receipts. For strategies involving related parties, ensure all transactions are at arm’s length and documented with fair market value support. The burden of proof is on the taxpayer to substantiate deductions.
What is the economic substance doctrine and how does it apply?
The economic substance doctrine (§7701(o)) requires that transactions have both objective economic substance (a reasonable possibility of profit) and subjective business purpose (a non-tax reason for the transaction). Transactions that lack economic substance are disregarded for tax purposes, and the 40% strict liability penalty applies. Legitimate tax planning strategies must have genuine business purposes beyond tax reduction.
How does this strategy affect state income taxes?
Federal tax strategies do not always produce the same results at the state level. Some states do not conform to federal tax law changes (e.g., bonus depreciation, QSBS exclusion). Taxpayers should model the state tax impact of any federal tax strategy, especially in high-tax states like California, New York, and New Jersey. Some strategies may save federal taxes while increasing state taxes.
What is the step-transaction doctrine and how does it apply?
The step-transaction doctrine allows the IRS to collapse a series of related transactions into a single transaction if the intermediate steps have no independent significance. This doctrine is used to prevent taxpayers from using artificial multi-step transactions to achieve tax results that would not be available in a single transaction. Legitimate tax planning strategies should have independent business purposes for each step.
How does this strategy interact with the passive activity loss rules?
Passive activity losses (§469) can only offset passive income. Active business income, wages, and portfolio income are not passive. Real estate rental income is generally passive unless the taxpayer qualifies as a Real Estate Professional. Passive losses that cannot be used currently are suspended and carried forward to offset future passive income or recognized when the passive activity is disposed of in a fully taxable transaction.
What is the at-risk limitation and how does it affect deductions?
The at-risk limitation (§465) limits deductions to the amount the taxpayer has at risk in the activity. At-risk amounts include cash invested, property contributed, and amounts borrowed for which the taxpayer is personally liable. Non-recourse debt (except qualified non-recourse financing for real estate) does not increase the at-risk amount. Losses in excess of the at-risk amount are suspended and carried forward.
How does this strategy affect the taxpayer’s basis in the business?
Basis tracking is essential for pass-through entities (S-Corps, partnerships). Contributions increase basis; distributions and losses decrease basis. A shareholder or partner cannot deduct losses in excess of their basis. Distributions in excess of basis are taxable as capital gains. Taxpayers should maintain a basis schedule and update it annually to track the impact of income, losses, and distributions.
How do I properly set up a Charitable Remainder Trust to comply with IRC §664 requirements?
To properly set up a Charitable Remainder Trust (CRT) under §664, the trust must be irrevocable and provide for a specified term of years (not exceeding 20) or for the life or lives of one or more non-charitable beneficiaries. The CRT must pay a fixed percentage (at least 5%) of the trust’s net fair market value annually to the income beneficiaries. Additionally, the remainder interest must be irrevocably dedicated to a qualified charity recognized under IRC §170(c). Proper legal drafting is essential to ensure compliance with the payout requirements and that the trust qualifies for the intended tax benefits.
What are the key steps for filing tax returns when a client has established a Charitable Remainder Trust?
The trustee of the CRT must file Form 5227 annually to report the trust’s financial activities, including distributions and charitable remainder valuations. Since the CRT is a grantor trust until the income interest begins, the initial tax filings may differ. After commencement, the trust files Form 1041, reporting income, deductions, and distributions, along with Schedule K-1s to income beneficiaries. It is critical to timely file Form 5227 and Form 1041 each year to avoid penalties and to maintain the trust’s tax-exempt status on its remainder interest.
What documentation should be maintained to support the valuation and charitable deduction claims for a CRT?
Documentation should include a qualified appraisal of contributed assets establishing the fair market value at the time of contribution, especially for non-cash assets. The trust instrument itself must be retained to demonstrate compliance with §664 requirements. Annual valuations of the trust's assets and actuarial calculations supporting the charitable deduction and payout rates should also be preserved. Maintaining comprehensive records helps substantiate the deduction under §170(f)(8) and withstand IRS scrutiny during audits.
What triggers IRS audit risk specifically related to Charitable Remainder Trusts?
Audit risk increases if there are discrepancies in valuation methods, failure to meet the minimum payout rate (5% per §664(d)(1)), or improper designation of remainder beneficiaries. Large charitable deductions without corresponding documentation or evidence of compliance with trust terms can also prompt audits. Additionally, CRTs funded with assets lacking clear market values or those with self-dealing concerns may attract IRS attention. Ensuring strict adherence to §664 and related regulations reduces audit exposure.
How should I advise a client who has both a Charitable Remainder Trust and a Donor-Advised Fund regarding charitable giving strategies?
While both vehicles offer tax benefits, a CRT provides an income stream along with a charitable deduction, whereas a Donor-Advised Fund (DAF) allows for immediate charitable deductions and more flexible grant-making. Clients should be advised that CRTs are irrevocable and subject to income distribution rules under §664, whereas DAFs permit ongoing contributions and grants without income requirements. Combining both can optimize philanthropic goals: CRTs for income and estate tax planning, and DAFs for flexible, ongoing charitable involvement.
Can a client combine a Charitable Remainder Trust with a Qualified Personal Residence Trust (QPRT) for estate planning, and what are the tax implications?
Combining a CRT with a QPRT can be part of an advanced estate plan to reduce estate taxes and provide charitable benefits. The QPRT removes the residence value from the estate while the CRT offers income tax deductions and eventual charitable gifts. However, careful coordination is required to ensure the timing of income streams and remainder interests align with IRC provisions, particularly §664 for CRTs and §2702 for QPRTs. The client should understand that the CRT's charitable remainder value reduces the taxable estate, while the QPRT transfers the residence interest out of the estate, providing complementary estate tax benefits.
What client-facing questions should I ask to determine if a Charitable Remainder Trust is appropriate?
Ask the client about their philanthropic goals, including desired timing and amount of charitable giving. Clarify their income needs and whether they seek a lifetime or term-based income stream. Assess the nature and value of assets available for funding the CRT, especially if non-cash or illiquid assets are involved. Inquire about estate planning objectives, including potential estate and gift tax concerns. These questions help determine if a CRT's income tax deduction, income stream, and eventual charitable remainder align with the client’s overall financial and charitable strategy.
