How CRTs Work
Step 1: contribute appreciated assets to an irrevocable Charitable Remainder Trust. The trust is established with you as the income beneficiary and a qualified charity as the remainder beneficiary. Common contribution assets: appreciated stock, business interests, real estate, or any asset with significant unrealized capital gain.
Step 2: the CRT sells the contributed assets. Because the trust is exempt from income tax (it's a charitable trust), the sale is tax-free at the trust level. The full proceeds remain in the trust.
Step 3: the trust invests the proceeds. Typically diversified — stocks, bonds, real estate. The CRT can own essentially any investment.
Step 4: the trust pays you (and/or other beneficiaries) income for the term. The income stream continues for the trust term — either a term of years (up to 20) or for the lifetime of one or more beneficiaries.
Step 5: at the end of the trust term, the remaining trust assets pass to the named charity (or charities). You don't get this back — it goes to charity permanently.
Concrete example: $5M of appreciated stock with $1M basis contributed to a 20-year CRT paying 6%. At contribution: charitable deduction (present value of remainder interest passing to charity), no capital gains tax. The trust sells the stock — tax-free — and invests $5M. Annual payment: 6% of trust value (variable for unitrust, fixed dollar for annuity trust). After 20 years: trust assets pass to charity. Cumulative income to you over 20 years: $6M-$12M (depending on investment performance).
CRAT vs CRUT: Two Structures
Charitable Remainder Annuity Trust (CRAT): pays a FIXED dollar amount each year, calculated as a percentage (5-50%) of the initial trust value. The annual payment doesn't change regardless of trust performance.
Charitable Remainder Unitrust (CRUT): pays a percentage of the trust value RECALCULATED each year. So as the trust grows or shrinks, the annual payment changes proportionally.
CRAT advantages: predictable income stream, no rebalancing math each year. CRAT disadvantages: no inflation protection, fixed payment can become inadequate over long terms.
CRUT advantages: payments grow with trust value (inflation hedge), can add additional contributions over time (CRATs can't accept additional contributions). CRUT disadvantages: payments fluctuate with markets, requires annual valuation.
Most charitable trusts use CRUT structure for the flexibility. CRAT is better for shorter terms or when predictable income matters more than growth.
NIMCRUT (Net Income Make-up CRUT): pays the lesser of unitrust amount or actual trust income, with shortfalls 'made up' in later years when income exceeds the unitrust amount. Useful for trusts holding assets that don't generate cash income (e.g., growth stocks).
Charitable Deduction Calculation
When you contribute assets to a CRT, you receive an immediate charitable deduction equal to the present value of the remainder interest passing to charity. This is calculated using IRS-prescribed actuarial methods based on: trust term, payout rate, applicable federal rate (AFR) for the month of contribution, and beneficiary ages (for life term trusts).
Higher payout rate = larger income to you = smaller charitable deduction. Lower payout rate = smaller income but larger deduction. The IRS requires that the charitable remainder must be at least 10% of the initial contribution value, capping the maximum payout rate at the level where the remainder calculation drops below 10%.
AFR matters: higher AFR = larger deduction (because future income is discounted more aggressively). Lower AFR = smaller deduction. Plan timing of contributions to coincide with higher AFR periods if possible.
Concrete example: 65-year-old contributing $1M to a CRUT with 5% payout, AFR of 5.0%. Charitable deduction: approximately $400K (40% of contribution value). 30% AGI limitation may apply (charitable contributions limited to 30% of AGI for capital gain property to public charities). Excess deduction carries forward 5 years.
If you're in a 35% federal bracket, the $400K deduction saves $140K of federal tax in the year of contribution. Plus state tax savings of $20K-$50K depending on state.
Income Tax Treatment of Distributions
CRT distributions to you are taxed using the 'tier system' specified in Section 664. The distribution is treated as having the character of income previously earned by the trust:
Tier 1: ordinary income (interest, dividends, short-term capital gains) — distributed to you as ordinary income.
Tier 2: capital gain (long-term capital gains) — distributed to you as long-term capital gain.
Tier 3: tax-exempt income (municipal bond interest) — distributed tax-free.
Tier 4: return of principal — tax-free.
The tiers are FIFO within each tier. You first 'use up' all Tier 1 income before any Tier 2 distributions, etc. So if the trust holds growth stocks generating mostly capital gains, your distributions will be primarily long-term capital gains — taxed at 15-20% federal vs. ordinary rates of 32-37%.
Strategic asset allocation within the trust: holding tax-efficient growth stocks creates Tier 2 (LTCG) income for distributions. Avoiding ordinary-income-generating bonds keeps distributions in lower-tax categories. Many CRT investors specifically structure portfolios to maximize favorable tier treatment.
When CRTs Make Sense
Strong fit: you have appreciated assets ($1M+) you'd otherwise sell, you have charitable intent (you would have given to charity anyway), you want ongoing income from the assets without paying capital gains, you're comfortable with irrevocable structure (assets are permanently in the trust).
Concrete example of strong fit: a couple in their 60s with $5M of appreciated stock from a tech company sale. They want to diversify out of the concentrated position. They have charitable intentions for some portion of their estate. Setting up a CRT achieves: capital gains avoidance on the diversification, immediate charitable deduction, ongoing income for life, eventual charitable benefit.
Poor fit: you don't have charitable intent (CRT permanently transfers assets to charity), you need full liquidity from your assets, you're young (CRT income for short remaining lifespan vs. retaining full ownership has different math), you have specific heirs you want to receive the assets (children/grandchildren — they're not the remainder beneficiary).
Estate planning aspect: CRT removes the contributed assets from your taxable estate. For ultra-high-net-worth donors approaching the federal estate exemption ($13.9M in 2026, scheduled to potentially halve after 2026), this can save significant estate tax.
CRT vs. straight charitable giving: a CRT lets you defer the charitable benefit and keep income from the assets. Direct charitable contributions give the assets to charity immediately. CRT is for those who want some economic benefit from the assets while still ultimately benefiting charity.
Setup Costs and Operational Considerations
CRT setup costs: typically $5K-$25K depending on complexity. You need an estate planning attorney specializing in charitable trusts to draft the trust document. A trustee (usually a bank or trust company) charges 0.5-1% annual fee for trust administration, investment management, and distributions.
Annual paperwork: CRTs file Form 5227 annually (information return), and beneficiaries receive K-1s for distributions. The trust must comply with various technical requirements to maintain charitable status.
Choice of trustee matters: you typically can't be your own trustee for a CRT (creates self-dealing concerns). Common trustees: corporate trust departments at major banks (Vanguard, Fidelity, Northern Trust), specialized charitable trust companies, professional trust officers at law firms.
Investment management: large trustees offer their own investment management. Specialized CRT investment platforms exist (e.g., Renaissance, Greater Horizons). Or you can hire an outside investment advisor while using a corporate trustee for administration only — this often produces lower total fees.
Naming charities: you can name multiple charitable beneficiaries with specified percentages. Some donors retain the right to change charitable beneficiaries during life (with limits), allowing flexibility as their philanthropic interests evolve.
Termination: CRTs are essentially impossible to terminate before the specified term. The IRS allows very limited modifications, mostly technical corrections. Don't establish a CRT thinking you can undo it — it's truly irrevocable.
