In mid-2026 the Martinez family—both in their early 60s—faced a classic concentrated-position dilemma. Over two decades Carlos had accumulated $4.2 million of highly appreciated employer stock (basis roughly $180,000). Selling outright would have produced a long‑term capital gain that threatened to push the couple into a materially higher marginal tax bracket and trigger additional surtaxes. They wanted liquidity, continued retirement income and to preserve a measure of philanthropic intent.

The plan they chose: a charitable remainder unitrust (CRUT)

Instead of a direct sale, the Martinezes funded a 10‑year charitable remainder unitrust (CRUT) with the appreciated shares. The CRUT sold the stock free of immediate capital gains tax, reinvested the proceeds in a diversified portfolio, and agreed to pay the couple 5% of the trust’s annual value as income for the 10‑year term. At the end of the term the remainder goes to a designated charity.

Key outcomes they sought:

  • Defer immediate recognition of the long‑term capital gain and the associated tax hit.
  • Smooth taxable income over a decade to avoid a single‑year spike in their tax bracket and the 3.8% NIIT exposure.
  • Obtain an upfront charitable income tax deduction (subject to AGI limits) to reduce current taxable income.
  • Secure a steady income stream that helps replace the cash they would have taken from a direct sale.

Why a CRUT worked for them

  • Tax-deferral on sale: Because the CRUT is a split‑interest vehicle, the trust can sell appreciated property without recognizing capital gain at that time. The gain is realized inside the trust’s tiered distribution system rather than all at once on the donors’ returns.
  • Immediate charitable deduction: Funding the CRUT generated a present‑value charitable deduction for the Martinez family, which reduced their adjusted gross income and helped keep them in a lower marginal tax bracket in the funding year.
  • Smoothing income: The 5% annual payout smoothed the cash flow they received and avoided a single year with a multi‑million dollar realized gain on their personal return.

Numbers and tax mechanics (illustrative)

Numbers below are illustrative and simplified to show mechanics; actual valuation, deduction and tax consequences depend on IRS actuarial tables, the trust payout rate, and prevailing interest assumptions at funding.

  • Gross sale value contributed to the CRUT: $4,200,000
  • Donor’s basis in the stock: $180,000 (long‑term)
  • Approximate charitable deduction (present value of remainder): $1.05M (subject to IRS calculation)
  • Annual CRUT payout at 5% of trust value (first year): roughly $210,000

Because the trust sells the stock, the capital gain is realized by the trust. Distributions to the Martinez family are taxed under the standard ordering rules (ordinary income first, then capital gains, then tax‑free return of principal). The immediate charitable deduction reduced their AGI in the funding year, which materially limited how far their marginal tax bracket rose in 2026.

Estimated taxes: avoiding an underpayment penalty

Despite the deferral of immediate capital gain on their personal returns, the Martinez family still expected significant taxable income from CRUT payouts and other sources (pensions, RMDs). They reviewed estimated‑tax obligations with their advisor and took these steps:

  1. Prepared a projection of taxable income for 2026 under the CRUT distribution scenario.
  2. Increased quarterly estimated payments for the remainder of the year to cover expected tax on trust distributions and other income, avoiding an underpayment penalty.
  3. Used safe‑harbor rules where helpful: paying 100% of prior‑year tax (or 110% for higher‑income taxpayers) to reduce exposure to estimated‑tax penalties, and topping up with current‑year payments as necessary.

Bottom line: proactive estimated‑tax payments kept the Martinez family from a surprise penalty the following spring and kept cash management predictable.

Filing status, deductions and credits

The couple filed Married Filing Jointly (MFJ). That choice influenced several outcomes:

  • MFJ provides higher threshold amounts for long‑term capital gains rates (0/15/20%) and larger standard deductions, both of which helped after the charitable deduction reduced AGI.
  • The charitable deduction from funding the CRUT was an itemized deduction; the family evaluated whether itemizing still made sense given the size of the donation deduction versus the standard deduction. In their case the deduction plus other itemizable items (state and local taxes, mortgage interest) exceeded the standard deduction.
  • They reviewed eligibility for other credits—none of which materially affected the sale strategy—but noted that certain nonrefundable credits are limited by taxable income and filing status.

State tax and other traps

Two practical warnings from this case:

  • State conformity: Some states treat charitable trusts and capital gains differently from federal rules. The Martinez advisors ran state returns for California and their state of residence to check for state capital gains exposure and state‑level deduction limits.
  • Charitable deduction AGI limits: The CRUT charitable deduction is subject to adjusted‑gross‑income percentage limits. Excess deductions may be carried forward, but the timing matters for bracket management.

Outcome and lessons

Over the first three years the CRUT provided the Martinez family with predictable cash flow and kept them in a lower marginal tax bracket than they would have occupied after an outright sale. They avoided a large, one‑time capital gains realization on their personal returns, obtained a significant charitable deduction in the funding year, and preserved some philanthropic impact via the remainder that will pass to charity after the trust term.

Key lessons for tax‑planning enthusiasts:

  • CRUTs can be an effective way to monetize concentrated, highly appreciated position while deferring immediate capital gains recognition—but they are not a free lunch. You trade immediate wealth for an income stream plus a charitable remainder.
  • Running the numbers matters: actuarial assumptions at funding determine both the charitable deduction and future payouts. Work with trustees and valuation experts.
  • Estimated taxes are often the overlooked follow‑through. Even when you defer capital gains from a sale into a trust, trust distributions and other income can create substantial current‑year tax liabilities—plan and pay quarterly to avoid penalties.
  • Filing status, itemized deductions, and credits interact. A large charitable deduction can reduce AGI and marginal‑bracket exposure, but state rules and AGI limits on deductions or credits must be modeled.
  • Compliance complexity is real: CRUTs require trust administration, trustee fees and careful tax reporting (Form 5227 and trust K‑1s). The administrative cost should be weighed against the tax benefits.

The Martinez case illustrates a practical, outcome‑focused use of a CRUT in 2026: deferring capital gains, smoothing taxable income to manage tax brackets and NIIT exposure, and addressing philanthropic goals. For any taxpayer with a concentrated position, the CRUT is one of several tools (others include charitable lead trusts, installment sales, and partial donations of stock); the best choice depends on cash needs, charitable intent, timeline and state tax considerations.

Consult your tax advisor and estate planner before implementing a CRUT. Small differences in trust terms, payout rate, or funding date can change the net tax and economic outcomes materially.
