7.3 Charitable Intent Strategies

Key Takeaways

  • Philanthropic exit planning enables business owners to eliminate federal and state capital gains taxes on private stock sales, generate substantial immediate income tax deductions, and establish multi-generational family philanthropic vehicles.

  • Transferring appreciated private company stock into a Charitable Remainder Unitrust (CRUT) prior to a sale allows the tax-exempt trust under IRC § 664 to sell 100% of the equity at a 0% capital gains rate, reinvesting gross proceeds to generate an annual income stream (5% to 50%) for the grantor.

  • A Flip-CRUT provides the ideal structure for illiquid private business stock, operating initially as a Net Income with Makeup CRUT (NIMCRUT) while the stock is illiquid and flipping into a standard percentage CRUT on January 1 following the sale of the business.

  • Contributing private company stock to a Donor-Advised Fund (DAF) yields a full fair market value charitable deduction up to 30% of AGI, whereas contributing private non-public stock to a Private Foundation restricts the deduction to cost basis under IRC § 170(e)(1)(B)(ii) and imposes a 1.39% excise tax.

  • Charitable stock gifts should be completed early, while the sale is still genuinely uncertain; in Hoensheid (2023) the donor was taxed on a gift made before the purchase agreement was signed because the sale was already virtually certain.

7.3 Charitable Intent Strategies

Note

Core Principle: In middle-market business transitions, philanthropic planning is far more than altruism—it is one of the most powerful tax mitigation and wealth preservation strategies available under the Internal Revenue Code. When an entrepreneur faces a $10M, $25M, or $50M liquidity event, capital gains taxes, the Net Investment Income Tax (NIIT), and state levies can consume 25% to 35%+ of the transaction proceeds. Integrating charitable vehicles allows the owner to transform involuntary tax payments into directed community impact, generate massive current income tax write-offs, and establish permanent family endowments.


Integrating Philanthropy into Business Exit Planning

Traditional financial advisors routinely commit a severe planning error: they allow a business owner to sell their enterprise, pay hundreds of thousands (or millions) of dollars in transaction taxes, and subsequently write checks to charities using their diminished post-tax cash.

Exit planning flips this equation through Pre-Sale Charitable Structuring:

TRADITIONAL (POST-SALE) APPROACH:          CEPA (PRE-SALE) APPROACH:
Owner Sells Stock                         Owner Gifts Stock to Charitable Vehicle
  ↓                                         ↓
Pays 25%–35% Capital Gains Tax            Vehicle Sells Stock at 0% Capital Gains Tax
  ↓                                         ↓
Donates After-Tax Cash to Charity         100% of Gross Proceeds Reinvested
  ↓                                         ↓
Partial Income Tax Deduction Claimed      Immediate FMV Income Tax Deduction Claimed

By transferring appreciated private company stock into a tax-exempt charitable vehicle prior to a sale, the owner eliminates corporate and personal capital gains taxes on the gifted interest, claims a current-year fair market value income tax deduction, and preserves 100% of the gross capital for investment and income generation.


Charitable Remainder Trusts (CRTs): Tax-Exempt Compounding & Income Preservation

A Charitable Remainder Trust (CRT), authorized under IRC § 664, is an irrevocable trust designed to split the economic value of an asset between non-charitable income beneficiaries (the business owner and/or their spouse) and qualified charitable organizations.

Core Structural Mechanics

  1. Stock Contribution: The founder transfers appreciated private company stock (often with zero or low tax basis) to the CRT prior to a transaction.
  2. Immediate Income Tax Deduction: The founder claims a federal income tax charitable deduction in the year of contribution equal to the actuarial present value of the charity's future remainder interest.
  3. Tax-Exempt Sale: Under IRC § 501(a) and IRC § 664(c), a CRT is a tax-exempt entity. When the CRT sells the stock to the M&A acquirer, it pays 0% capital gains tax! The full 100% gross purchase price is retained within the trust.
  4. Gross Compounding: The entire pre-tax proceeds are reinvested into a diversified portfolio, compounding at a far higher base than would be possible if taxes had been subtracted.
  5. Income Distributions: The trust pays an annual income distribution to the founder for life or for a term of up to 20 years.
  6. Charitable Remainder: Upon trust termination, the remaining principal passes to one or more qualified charities, family Donor-Advised Funds, or private foundations.

Statutory Qualification Mandates

To qualify as a valid CRT under IRC § 664, the trust instrument must satisfy three strict statutory tests:

  • The 5% Minimum Payout Rule: The annual distribution to the income beneficiary must be at least 5% of the initial trust value (for a CRAT) or 5% of the annual revalued trust value (for a CRUT) (IRC § 664(d)(1)(A) / (d)(2)(A)).
  • The 50% Maximum Payout Rule: The annual distribution cannot exceed 50% of the trust value.
  • The 10% Minimum Remainder Test: Under IRC § 664(d)(1)(D) and § 664(d)(2)(D), the actuarial present value of the charitable remainder interest must equal at least 10% of the initial fair market value of the property contributed to the trust, calculated using the statutory discount rate under IRC § 7520.

The Four-Tier Distribution Accounting Rules (IRC § 664(b))

While the CRT pays 0% capital gains tax upon selling the business stock, distributions received by the income beneficiary are taxed pursuant to a strict "Worst-In, First-Out" (WIFO) Four-Tier Accounting System under IRC § 664(b):

Distribution TierTax Character of DistributionAccounting Priority
Tier 1Ordinary Income (interest, non-qualified dividends, trade income)Taxed at top ordinary rates (up to 37%) to the extent of current and accumulated undistributed ordinary income.
Tier 2Capital Gains (short-term first, then long-term)Taxed at preferential capital gains rates (20% + 3.8% NIIT) to the extent of realized capital gain from the stock sale.
Tier 3Tax-Exempt Income (municipal bond interest)Received completely income-tax-free after Tier 1 and Tier 2 balances are fully exhausted.
Tier 4Return of Principal (corpus)Received completely tax-free as a return of contributed basis.

Because the CRT sells appreciated stock in Tier 2, annual unitrust checks to the founder are typically taxed at favorable long-term capital gains rates (Tier 2) over several decades, effectively deferring transaction taxes across the owner's lifespan.

Warning

S Corporation Stock and CRTs Do Not Mix: A charitable remainder trust is not an eligible S corporation shareholder, so transferring S-corp stock to a CRT terminates the company's S election. CRTs also pay a 100% excise tax on any unrelated business taxable income. Owners of S corporations need specialist structuring before any charitable gift of their shares.

Pre-Sale Flip-CRUT Exit Architecture vs. Direct Sale

CRUT vs. CRAT: Structural Variations & The Flip-CRUT Solution

CRTs fall into two primary statutory categories: Charitable Remainder Annuity Trusts (CRATs) and Charitable Remainder Unitrusts (CRUTs).

Charitable Remainder Annuity Trusts (CRATs)

  • Fixed Dollar Distribution: A CRAT pays a predetermined fixed dollar amount every year, established at inception as a percentage of initial value (e.g., $60,000 per year on a $1,000,000 contribution).
  • No Revaluation: The payment never changes, regardless of whether the trust portfolio grows to $10,000,000 or drops to $500,000.
  • No Subsequent Contributions: Under IRC § 664(d)(1)(C), a CRAT can never accept additional contributions after initial funding.
  • The 5% Probability of Exhaustion Test (Rev. Rul. 77-374): A CRAT is strictly disqualified if there is more than a 5% actuarial probability that the trust corpus will be completely exhausted before the non-charitable beneficiary passes away.

Charitable Remainder Unitrusts (CRUTs)

  • Variable Percentage Distribution: A CRUT pays a fixed percentage (e.g., 6%) of the trust assets revalued annually on the first business day of the year.
  • Built-in Inflation Hedge: If the trust portfolio doubles from $2M to $4M, the 6% payout check doubles from $120,000 to $240,000 per year.
  • Permits Additional Contributions: Under IRC § 664(d)(2)(C), donors can make ongoing contributions to a CRUT across subsequent tax years.

The Illiquid Stock Dilemma: Why Standard CRUTs Fail Prior to Exit

While a standard CRUT is structurally superior to a CRAT, contributing privately held business stock into a standard CRUT creates an immediate liquidity crisis:

  • Operating company stock is illiquid and pays little or no cash dividends.
  • A standard CRUT is legally required to distribute its fixed percentage (e.g., 6%) in cash every single year.
  • If the M&A transaction is delayed by 9 to 18 months due to regulatory scrutiny or financing hiccups, the trustee has zero liquid cash to pay the mandatory unitrust distribution, forcing a technical default.

The Solution: The Flip-CRUT (Treas. Reg. § 1.664-3(a)(1)(i)(c))

To eliminate this liquidity trap, exit planners utilize a specialized hybrid vehicle authorized by Treasury Regulations: the Flip-CRUT.

A Flip-CRUT operates across two distinct lifecycle phases:

FLIP-CRUT LIFECYCLE:
├── Phase 1: Pre-Sale Illiquid Holding Period
│   └── Operates as NIMCRUT (distributes only actual net income: $0)
├── The Triggering Event: Sale of unmarketable operating business stock
└── Phase 2: Post-Sale Liquid Portfolio
    └── Flips on January 1 following sale into Standard CRUT (pays fixed % annually)
  1. Phase 1 (The NIMCRUT Stage): Prior to the exit, the trust is structured as a Net Income with Makeup CRUT (NIMCRUT). Under IRC § 664(d)(3), the trustee distributes only the trust's actual net accounting income (which is $0.00 while holding private stock). The unpaid percentage amounts are tracked in a cumulative "makeup account."
  2. The Permissible Triggering Event: Treasury Regulation § 1.664-3(a)(1)(i)(c) specifically permits the trust agreement to designate the sale of "unmarketable assets" (private business stock) as an objective, non-discretionary Triggering Event.
  3. Phase 2 (The Standard CRUT Stage): On January 1 of the calendar year following the sale date, the trust automatically "flips" into a standard fixed-percentage CRUT. Any makeup amount accumulated during the NIMCRUT phase is forfeited at the flip. With the $3,000,000 or $10,000,000 cash proceeds now safely invested in liquid, yield-bearing assets, the trustee pays the full unitrust percentage each year without default risk.

Worked Mathematical Case Study: Pre-Sale Flip-CRUT vs. Direct Cash Sale

To understand the quantitative power of pre-sale charitable exit planning, examine founder Marcus Sterling, sole owner of Sterling Industrial Controls Corp:

  • Stock Contributed to Philanthropic Strategy: $3,000,000 fair market value.
  • Tax Basis in Stock: $0.00 (founded from scratch).
  • Tax Environment: 20% federal capital gains + 3.8% Net Investment Income Tax (NIIT) + 6.0% state capital gains = 29.8% effective combined capital gains tax rate.
  • Founder Profile: Marcus is 62 years old and wants a 6.0% annual income stream for life, with the remainder dedicated to funding an engineering scholarship endowment at his alma mater.

Path A: Direct Cash Sale Followed by After-Tax Charitable Contribution

In this conventional, unoptimized scenario, Marcus sells 100% of his stock in the acquisition, pays all transaction taxes personally, and donates $1,000,000 in cash to the university endowment.

Step 1: Capital Gains Tax Calculation

Taxable Capital Gain=$3,000,000−$0.00=$3,000,000\text{Taxable Capital Gain} = \$3{,}000{,}000 - \$0.00 = \$3{,}000{,}000

Capital Gains Tax Paid=$3,000,000×29.8%=$894,000\text{Capital Gains Tax Paid} = \$3{,}000{,}000 \times 29.8\% = \$894{,}000

Net Cash Retained by Marcus=$3,000,000−$894,000=$2,106,000\text{Net Cash Retained by Marcus} = \$3{,}000{,}000 - \$894{,}000 = \$2{,}106{,}000

Step 2: Charitable Gift of Cash

Marcus cuts a $1,000,000 cash check to the university endowment:

  • Remaining Liquid Capital for Marcus: $2,106,000 - $1,000,000 = $1,106,000.
  • Charitable Tax Deduction: Marcus claims a $1,000,000 cash charitable deduction. At a 40% top ordinary income rate, this saves $400,000 in cash taxes against other income.
  • Annual Retirement Cash Flow: Marcus invests the remaining $1,106,000 into a diversified portfolio yielding 6.0% annually: Annual Cash Flow=$1,106,000×6.0%=$66,360 per year\text{Annual Cash Flow} = \$1{,}106{,}000 \times 6.0\% = \$66{,}360\text{ per year}
  • Charity Endowment Received: Exactly $1,000,000.

Path B: Pre-Sale Contribution of $3,000,000 Stock to a 6% Flip-CRUT

Now, Marcus works with his CEPA to execute a pre-sale contribution of the $3,000,000 private stock to a Flip-CRUT before signing a definitive purchase agreement.

Step 1: Upfront Charitable Income Tax Deduction

Using IRS actuarial tables (IRC § 7520 discount rate assumed at 5.0%), the present value of the charitable remainder interest for a 62-year-old donor electing a 6.0% unitrust payout is calculated at 31.2% of the transferred stock value: Charitable Income Tax Deduction=$3,000,000×31.2%=$936,000\text{Charitable Income Tax Deduction} = \$3{,}000{,}000 \times 31.2\% = \$936{,}000

At Marcus's 40% ordinary income tax rate, this deduction saves $374,400 in direct cash taxes against outside income.

Note

2026 deduction limits: These examples use a 40% combined rate for simplicity. A deduction for appreciated stock given to a public charity or a CRT benefiting one is limited to 30% of AGI each year, with a five-year carryforward. From 2026, the One Big Beautiful Bill Act also disallows the first 0.5% of AGI of itemized charitable gifts and caps their value at 35% for taxpayers in the 37% bracket, so actual savings depend on the donor's income and state.

Step 2: Tax-Exempt Sale at Closing

The Flip-CRUT sells the stock to the acquirer for $3,000,000 cash:

  • Capital Gains Tax Paid by Trust: $0.00 (Tax-exempt under IRC § 501(a)).
  • Full Cash Principal Reinvested: $3,000,000.

Step 3: Annual Unitrust Cash Flow

On January 1, the trust flips to a standard CRUT paying 6.0% of fair market value annually: Year 1 Distribution to Marcus=$3,000,000×6.0%=$180,000 per year\text{Year 1 Distribution to Marcus} = \$3{,}000{,}000 \times 6.0\% = \$180{,}000\text{ per year}

Under Tier 2 rules, this $180,000 is taxed to Marcus at favorable capital gains rates (29.8% combined), netting Marcus $126,360 after-tax every single year.

Step 4: Projected Remainder to Charity

Assuming the CRT portfolio earns an average annualized return of 7.5% and distributes 6.0% annually, the trust principal will grow over Marcus's 22-year actuarial life expectancy, projecting an ultimate charitable distribution to the university of over $4,100,000!

Charitable Lead Trusts (CLTs): The Multi-Generational Wealth Accelerator

A Charitable Lead Trust (CLT) is the structural mirror image of a Charitable Remainder Trust:

  • Income to Charity First: The trust pays an annual income stream to designated charities for a fixed term of years or for the donor's life.
  • Remainder to Heirs: Upon termination of the lead term, the remaining trust principal passes to non-charitable remainder beneficiaries—typically the donor's children, grandchildren, or an irrevocable dynasty trust.
CHARITABLE LEAD TRUST (CLT) FLOW:
├── 1. Grantor funds CLT with appreciating business stock
├── 2. Trust pays annual annuity or unitrust to Charity for term of years
└── 3. Remaining principal transfers to Children / Dynasty Trust (free of estate/gift tax)

CLAT vs. CLUT

  • Charitable Lead Annuity Trust (CLAT): Pays a fixed dollar amount annually to charity. Like a GRAT, a CLAT can be "zeroed out" under IRC § 7520. If the trust assets appreciate at an annualized rate higher than the § 7520 hurdle rate, that entire excess growth passes to the founder's children with zero gift tax and zero unified exclusion consumed.
  • Charitable Lead Unitrust (CLUT): Pays a fixed percentage of annual revalued assets to charity. The payout fluctuates with portfolio performance.

Non-Grantor CLAT as a Wealth Transfer Powerhouse

In exit planning, the Non-Grantor CLAT is frequently deployed when a business owner has strong philanthropic goals and also wants to pass substantial equity appreciation to the next generation without gift tax. Because the trust is a separate taxable entity under IRC § 641, it is allowed an unlimited charitable income tax deduction under IRC § 642(c) for gross income paid to charity, offsetting income taxes generated inside the trust while transferring millions in residual equity to heirs.

Donor-Advised Funds (DAFs) vs. Private Foundations

When business owners establish outright charitable vehicles, the primary choice is between a Donor-Advised Fund (DAF) and a Private Non-Operating Foundation.

The Decision Matrix

Structuring DimensionDonor-Advised Fund (DAF)Private Non-Operating Foundation
Tax ClassificationPublic Charity (Sponsored by Fidelity, Schwab, Community Foundations)Private Foundation (Separate 501(c)(3) legal entity)
Private Stock Deduction LimitFair Market Value (FMV) up to 30% of AGI (5-year carryforward under IRC § 170(b)(1)(C))Lesser of Cost Basis or FMV up to 20% of AGI (IRC § 170(e)(1)(B)(ii))
Excise Tax on Investment Income0% (Completely exempt)1.39% flat excise tax on net investment income (IRC § 4940)
Mandatory Annual DistributionNo statutory minimum (Active grantmaking encouraged)Mandatory 5% distribution of net investment assets annually (IRC § 4942)
Self-Dealing ProhibitionsGoverned by sponsoring public charityStrict absolute prohibition under IRC § 4941; severe excise tax penalties
Public Disclosure & Reporting100% Anonymous; no separate public tax returnPublic inspection of Form 990-PF (disclosing all assets, trustee fees, grants)
Startup & Operational OverheadZero legal setup costs; nominal administrative fee (0.2%–0.6%)Significant legal, accounting, and board governance expenses ($15k–$30k+ setup)

Warning

The Fatal Private Foundation Basis Trap (IRC § 170(e)(1)(B)(ii)): One of the most catastrophic errors an advisor can make is recommending that an owner contribute zero-basis private operating company stock to a Private Foundation prior to an exit. Under IRC § 170(e)(1)(B)(ii), income tax deductions for gifts of appreciated property to a private foundation are strictly limited to the donor's cost basis (unless the asset is "qualified appreciated stock" of a publicly traded corporation under § 170(e)(5)).

If a founder contributes $5,000,000 of private stock with a $0 basis to a Private Foundation, their federal income tax deduction is $0.00! By contrast, contributing that same $5,000,000 of private stock to a Donor-Advised Fund (a public charity) yields a full $5,000,000 fair market value deduction (saving up to $2,000,000 in cash taxes).


The Critical Pre-Sale Contribution Rule: Assignment of Income & Rev. Rul. 78-197

Just as with family trust transfers, pre-sale charitable gifts are vulnerable to the Anticipatory Assignment of Income Doctrine if executed too late in the deal cycle.

What Revenue Ruling 78-197 Does and Does Not Protect

In Revenue Ruling 78-197, following the Tax Court's decision in Palmer v. Commissioner (62 T.C. 684 (1974)), the IRS said it would treat redemption proceeds as income to a donor of stock only if the charity was legally bound, or could be compelled by the corporation, to surrender the shares for redemption. That ruling is a useful starting point, but it is not a safe harbor for sales to outside buyers. Courts apply a broader realities-and-substance test: if the sale was practically certain when the gift was made, the gain is taxed to the donor even though the charity had no legal obligation to sell (Ferguson v. Commissioner; Estate of Hoensheid v. Commissioner, T.C. Memo. 2023-34).

The M&A Deal Spectrum: How Risk Rises Over Time

DEAL PROCESS TIMELINE & CHARITABLE CONTRIBUTION RISK:

[ Teaser / CIM ] --> [ Non-Binding LOI ] --> [ Due Diligence ] --> [ Definitive SPA ] --> [ Closing ]
  LOWEST RISK          RISING RISK             HIGH RISK              VERY HIGH RISK
  Best time to give    Real contingencies      Practical-certainty    Gain imputed to donor
                       must remain open        test (Hoensheid)
  1. Before a Letter of Intent: The Safest Window. No buyer has committed to terms and the outcome is genuinely uncertain. This is the best time to complete charitable gifts of stock.
  2. After a Non-Binding LOI: Rising Risk. The economic terms of an LOI are usually non-binding, but courts look at the realities. The more diligence is complete, financing is lined up and the deal is on track, the more likely a court finds the sale was practically certain. In Hoensheid, a gift made two days before closing failed even though the final agreement was not yet signed.
  3. After the Definitive Purchase Agreement: Too Late. Once the Stock Purchase Agreement or merger agreement is signed, a gift will almost certainly be treated as an assignment of income, taxing the gain to the donor and shrinking the charitable benefit.

Tip

CEPA Practical Protocol for Charitable Stock Gifts:

  1. Complete the gift (deed of gift and transfer on the corporate ledger) as early as possible, ideally before an LOI is signed, while real contingencies remain.
  2. Ensure the charity or CRT trustee retains independent legal discretion to vote on or reject the transaction.
  3. For a gift of non-publicly traded stock worth more than $10,000, obtain a qualified appraisal from a qualified appraiser (IRC § 170(f)(11); Treas. Reg. § 1.170A-17), made no earlier than 60 days before the gift, and file Form 8283. The Hoensheid donor lost the deduction entirely for failing this step.
Test Your Knowledge

Why is a Flip-Charitable Remainder Unitrust (Flip-CRUT) recognized as the premier charitable vehicle for holding illiquid private business stock prior to an M&A exit?

A

It requires the charitable beneficiary to indemnify the business owner against all historical corporate tax liabilities under state commercial codes.

B

It allows the donor to revoke the trust and retrieve all contributed stock if the prospective buyer reduces their valuation multiple during due diligence.

C

It guarantees that the buyer of the business can claim an immediate 100% bonus depreciation write-off on all purchased stock.

D

It starts as a NIMCRUT that pays only actual income while holding illiquid shares, then flips to a standard unitrust on January 1 after the sale

Test Your Knowledge

An entrepreneur planning a $20,000,000 exit wishes to contribute $2,000,000 of zero-basis private operating company stock to a philanthropic entity before the sale. What is the tax deductibility consequence of contributing this stock to a Private Non-Operating Foundation compared to a Donor-Advised Fund (DAF)?

A

The DAF gives a $2,000,000 fair market value deduction (up to 30% of AGI); the private foundation deduction is limited to basis, which here is $0

B

The private foundation allows a fair market value deduction of up to 50% of AGI, while a donor-advised fund limits the deduction to 10% of AGI

C

The DAF restricts the deduction to cost basis, whereas the Private Foundation provides an immediate fair market value deduction.

D

Both entities provide identical fair market value deductions of up to 60% of AGI, and neither one pays any excise tax on its investment income

Test Your Knowledge

Under the anticipatory assignment of income doctrine, when does a charitable gift of private company stock made before a sale risk having the capital gain taxed to the donor?

A

Whenever the charitable contribution occurs in the same calendar year as an M&A transaction, regardless of documentation status.

B

When the sale is practically certain at the time of the gift, whether because the charity must sell or because the deal has ripened

C

Whenever the business owner signs a non-binding Letter of Intent (LOI) that contains customary exclusivity and confidentiality provisions.

D

When the donor retains the right to recommend grant recipients from the resulting philanthropic fund.
