QSBS and Charitable Planning: DAF, CRT, and Pre-Exit Giving Strategies

For philanthropically-minded founders, donating QSBS shares before a sale can eliminate gain entirely — no federal capital gains tax, no AMT, no Section 1202 math needed. But the planning window closes when a binding sale agreement is signed, and the right charitable structure depends on whether you want a deduction now, income later, or both.

The two paths: exclusion versus donation

Most QSBS planning focuses on the Section 1202 exclusion: sell qualified shares, exclude up to $15M of gain (for post-July-4-2025 stock), and pay no federal tax on what's excluded. But the exclusion is only one way to avoid tax on QSBS gain. The other is not selling at all.

When you donate appreciated QSBS shares directly to a qualifying charity or donor-advised fund (DAF), you:

Recognize no capital gain — there is no sale, so no gain event occurs.
Claim a charitable deduction equal to the shares' fair market value on the date of the gift.
Transfer the shares to an organization that can sell them without recognizing taxable income.

For a founder with charitable intent, this outcome is frequently better than using the Section 1202 exclusion: you avoid all of the gain on donated shares (not just up to the cap), receive a deduction against ordinary income, and the charity gets the full FMV.

When donation beats exclusion: If you plan to give 20% of your exit proceeds to charity anyway, donating 20% of the shares before the sale eliminates gain on that portion entirely — rather than selling, paying tax on whatever exceeds the exclusion, and then donating after-tax cash.

Donating QSBS to a donor-advised fund (DAF)

A donor-advised fund is a charitable account sponsored by a public charity (Fidelity Charitable, Schwab Charitable, Vanguard Charitable, and specialized platforms like Charityvest or National Philanthropic Trust). You contribute assets to the DAF, receive an immediate charitable deduction, and recommend grants to qualifying charities over time.

Tax treatment of a QSBS-to-DAF contribution

No capital gains tax on the donated shares — the contribution is not a sale.
Charitable deduction equal to FMV on the date of contribution, subject to the 30% of AGI limit for long-term capital gain property.¹
Unused deduction carries forward for up to five additional tax years.
The DAF sells the shares as a tax-exempt entity — no gain recognized inside the fund.

2026 OBBBA changes to charitable deductions

Two new limits took effect in 2026 under the One Big Beautiful Bill Act:²

0.5% AGI floor: Only contributions exceeding 0.5% of your AGI are deductible. At $1M AGI, the first $5,000 of charitable contributions is not deductible. For a founder with $5M in QSBS and $600K AGI, the floor reduces the deduction by $3,000 — a minor impact relative to the gain avoided.
35% deduction cap: The tax benefit of itemized charitable deductions is capped at 35% even for filers in the 37% bracket. A $1M deduction yields a maximum $350,000 reduction in tax — instead of $370,000. Still highly favorable compared to paying 23.8% capital gains tax.

Which DAFs accept private company shares

Not all DAFs accept illiquid, pre-IPO stock. The major platforms (Fidelity Charitable, Schwab Charitable, Vanguard Charitable) accept private company shares but have minimum contribution amounts and liquidity review requirements — typically they want confidence the shares can be sold within a reasonable timeframe. Specialized platforms (National Philanthropic Trust, Goldman Sachs Philanthropy Fund) and planned giving offices at universities or hospitals may have more experience with complex founder equity situations.

Contact the DAF before the transaction is announced. Processing private company shares takes time, and the contribution must be completed before a binding sale agreement is signed.

Donating directly to a public charity

A direct donation of QSBS shares to a university, hospital, community foundation, or other qualifying public charity provides the same tax treatment as a DAF contribution — no capital gain, FMV deduction, 30% AGI limit — but you forgo the DAF's flexibility. The charity immediately decides what to do with the shares. This approach works best when you have a specific charitable recipient in mind and are willing to make the gift irrevocably and without timing flexibility.

The anticipatory assignment of income risk

The most important rule in charitable QSBS planning: the donation must be completed before a binding commitment to sell exists.³

Under the anticipatory assignment of income doctrine, if a taxpayer gives away a right to receive income after the income has become fixed and determinable, the IRS can treat the gift as if the donor received the income and then gave it away — taxing the gain to the donor even though the donor gave the shares, not cash. In a QSBS context, this means:

A signed letter of intent, term sheet, or merger agreement that obligates the sale may close the window for a valid pre-sale charitable donation.
"Pre-LOI" does not mean "safe." If facts and circumstances show a sale was effectively certain before the gift was made, the doctrine can still apply.
Informal conversations with a buyer — even at term sheet stage — are not automatically a problem, but the closer the gift is in time to a signed agreement, the more scrutiny it faces.

Practical rule: Complete charitable donations of QSBS at least 30 to 90 days before any expected LOI, and well before any acquisition discussions become exclusive. The same timing window that applies to gifting and stacking applies here — see the gifting and stacking guide.

Charitable Remainder Trust (CRT) with QSBS

A Charitable Remainder Trust is a tax-exempt irrevocable trust that receives assets, sells them tax-free, pays an income stream to one or more non-charitable beneficiaries (typically you), and distributes the remaining principal to charity at the trust's termination.⁴ In a QSBS context, a CRT provides a middle path between "sell everything now" and "give everything away."

How a QSBS CRT works

Transfer QSBS shares to the CRT before a binding sale agreement. The transfer is treated as a gift for §1202 purposes — QSBS status and holding period are preserved inside the trust, though the exclusion may not be utilized (see below).
The CRT sells the shares. Because the trust is tax-exempt, no gain is recognized on the sale inside the trust. The full proceeds are available for investment.
You receive an income stream. The trust pays you (or you and a spouse) a fixed percentage of the initial contribution value each year (charitable remainder annuity trust, CRAT) or a fixed percentage of the trust's current value each year (charitable remainder unitrust, CRUT). Minimum payout is 5% per IRS rules; the IRS requires the charitable remainder value to be at least 10% of the initial trust contribution at the time of funding.
Distributions are taxed in tiers. The tier system applies ordinary income first, then capital gains, then corpus. Because the CRT holds all proceeds as a pool, capital gains realized inside the trust flow through to beneficiaries as capital gain distributions before corpus distributions — offering deferral, but not elimination, of capital gains tax. Distributions are typically spread over years or decades, allowing deferral and potentially lower rates if your income is lower in later years.
Charitable deduction at funding. You receive a partial deduction in the year you fund the trust, equal to the present value of the charitable remainder interest calculated under IRS actuarial tables. For a 50-year-old contributing $5M to a 20-year CRUT at 5% payout, the remainder interest might be approximately $1.5–2M, generating a comparable deduction (subject to the 30% AGI limit and 5-year carryforward).

QSBS stacking question in a CRT

A CRT may qualify as a separate taxpayer for Section 1202 exclusion purposes, since it is a separate legal entity and beneficiaries are treated as having acquired their interest in the trust — not the underlying QSBS. However, because the CRT is tax-exempt, the exclusion is not needed for gain at the trust level: the trust pays no tax on the sale regardless. The stacking benefit applies only if the distributed income to beneficiaries can be characterized as excluded gain — which remains an unsettled area without clear IRS guidance.⁵

Do not rely on CRT QSBS stacking to produce a tax-free result at the beneficiary level without current legal analysis.

When a CRT makes sense

A CRT is best suited for founders who:

Want a guaranteed income stream in retirement rather than a lump-sum payout.
Have a large gain that exceeds the §1202 exclusion cap and want to defer, not eliminate, capital gains tax on the excess.
Have charitable intent for a meaningful portion of their estate and want to integrate it with their retirement income plan.
Are not California residents (CRTs offer little state tax relief for CA residents because CA taxes CRT distributions as ordinary income regardless).

Comparison: three charitable approaches to QSBS gain

Strategy	Tax on donated shares	Charitable deduction	Income to founder	Complexity
Direct donation to charity	None — no sale	FMV (30% AGI limit)	None	Low
Donate to DAF	None — no sale	FMV (30% AGI limit)	None (grants to charities later)	Low–Medium
Charitable Remainder Trust (CRT)	None at trust level; deferred & tiered to beneficiary	Present value of remainder (30% AGI limit)	Annual payout for life or term	High — requires trust, attorney, trustee

State tax interaction

Charitable QSBS planning reduces federal gain. Its effect on state tax depends on your state:

California, Pennsylvania, Alabama, Mississippi do not conform to the §1202 exclusion, but donating QSBS to a DAF means there is no sale — so no state capital gain to worry about for the donated shares. However, CA may tax CRT distributions as ordinary income.⁶
Conforming states: If you could have excluded the gain anyway, donating the shares primarily benefits the federal deduction rather than state tax avoidance — the state would have followed the §1202 exclusion on the federal side.
Non-conforming state residents benefit most from donating QSBS shares rather than selling, because they avoid both federal gain (via donation) and state gain (via no-sale) — whereas a straight §1202 exclusion eliminates only the federal gain, leaving the state gain fully taxable.

For California founders with large QSBS positions that exceed the exclusion cap, donating the excess shares pre-sale eliminates both federal and California capital gain on those shares. This is one of the most compelling scenarios for QSBS charitable planning.

See the QSBS state tax conformity guide for current state-by-state conformity details.

Worked example: DAF donation plus §1202 exclusion

A California founder holds $40M in QSBS (pre-OBBBA stock, $1M basis). She plans to sell in an acquisition at $40M. Her situation:

§1202 exclusion available: $10M (greater of $10M cap or 10× $1M basis).
Federal gain: $39M total. Excluded: $10M. Taxable: $29M at ~23.8% = ~$6.9M federal tax.
California gain: full $39M at ~13.3% = ~$5.2M California tax.
Total tax without charitable planning: ~$12.1M.

She decides to donate $8M in shares to a DAF before any LOI is signed, then sell the remaining $32M in shares:

DAF donation: $8M gain eliminated. Charitable deduction: $8M FMV (limited to 30% AGI; carryforward for remainder). No federal or California capital gains on donated shares.
Remaining $32M sold: $31M gain. §1202 exclusion: $10M (basis now $800K retained shares; exclusion = 10× $800K = $8M, or the $10M cap — cap is greater). Taxable federal gain: $21M × 23.8% ≈ $5M. California gain: $31M × 13.3% ≈ $4.1M.
Total tax with charitable planning: ~$9.1M plus charitable deduction value of ~$2.8M (at 35% cap) = net economic benefit of ~$5.8M vs. the no-planning scenario.

The actual math depends on basis allocation, AGI, carryforward use, and deduction cap — but the direction is clear: donating shares to a DAF before an acquisition is a material planning lever for California founders with gain exceeding the exclusion cap.

When to start and who to involve

Start charitable planning 12–18 months before an anticipated exit. DAF account setup, trust formation, and DAF review of private shares all take time. Rushing near an LOI creates both assignment-of-income risk and operational risk.
Coordinate with your estate plan. Charitable giving reduces the estate, which affects estate tax (and lifetime exemption consumption). The $15M OBBBA estate exemption is permanent, but gifting to charity and gifting to family compete for the same pre-LOI planning window.
Model the full picture before committing. A fee-only financial advisor can run scenarios: donate X% vs. retain and exclude vs. stacking + gifting + donate. The optimal blend depends on your giving goals, income needs, state, and basis.
Get legal review before the transfer. Trust formation for a CRT requires an attorney. DAF contributions to private shares require the DAF sponsor's acceptance. Gift documentation must be completed before any LOI or term sheet.

Get matched with a QSBS charitable planning advisor

Combining the §1202 exclusion with DAF or CRT strategies requires coordination across a fee-only advisor, CPA, and estate attorney — and the planning window closes at the LOI. Tell us where you are in the process and we will match you with an advisor experienced in founder liquidity and charitable planning.
