DAF (Donor Advised Fund) Timing Around an Equity Liquidity Event

A senior IC at an IPO-year company sees $3M of RSUs vest and sells $500K to cover the tax hit. Their AGI is $4M for the year. They’d like to do something charitable and get a tax deduction. A Donor Advised Fund is usually the right tool.

Contributing $500K of appreciated employer stock to a DAF generates a federal charitable deduction at fair market value, up to 30% of AGI for appreciated property under IRC §170(b)(1)(C)(ii). The taxpayer avoids the capital gains tax on the donated shares entirely. The DAF then liquidates the stock (tax-free to the DAF as a §501(c)(3) entity) and holds the cash for future grants to public charities.

Timing the DAF contribution to the liquidity year captures the deduction in the year with peak income, the year when the deduction is worth the most.

How a DAF works

A Donor Advised Fund is a charitable giving account held at a sponsor (Fidelity Charitable, Schwab Charitable, Vanguard Charitable, community foundations, etc.).

Mechanics:

1. Donor contributes assets (cash, stock, real estate, other) to the DAF
2. Donor receives immediate tax deduction at fair market value (for stock held >1 year) in the contribution year
3. Contributed assets are owned by the sponsor; donor retains advisory privileges
4. Donor recommends grants to IRS-qualified public charities over time (no annual distribution requirement)
5. Sponsor invests the balance in donor-selected options

The 30% AGI limit

Under IRC §170(b)(1)(C)(ii), appreciated property donations to public charities (including DAFs) are limited to 30% of AGI. The remaining 70% is cash-ceiling or other asset type.

For a $4M AGI taxpayer:

• Maximum appreciated-stock deduction: $1.2M (30% of $4M)
• Additional cash donations limit: 60% of AGI minus stock donations = up to $2.4M total (60% cap for cash)

Excess contributions carry forward for 5 years. A $3M appreciated stock donation on $4M AGI gets $1.2M deduction in year 1, $1.2M max in year 2 (if AGI continues), and remaining $600K available through year 5 maximum.

Fair market value rule for stock

Long-term appreciated stock (held >1 year) donated to a DAF gets fair market value deduction. Short-term appreciated stock (held ≤1 year) is deducted only at basis, which is usually near-zero for recently-vested RSUs.

For RSU donations: each lot needs >1-year holding period from vest date to qualify for fair-market-value treatment. Vest dates matter. Don’t donate the tranche that vested last week; donate the tranche from 14+ months ago.

The capital gains avoidance benefit

The key benefit: appreciated stock donation avoids capital gains tax on the donated shares.

Example: 1,000 shares with basis $60K, FMV $500K.

• Sell and donate cash: $440K capital gain, $104K federal tax (23.8%), net donation $396K, deduction $396K
• Donate stock directly: No capital gain, deduction $500K

Net benefit of donating stock vs selling and donating cash: $104K less tax. This is 20% of the donation value.

For higher basis stock, the benefit is smaller. For stock with low basis (like recent RSU vests where basis is near current FMV), the benefit exists but is smaller as well.

IPO-year advantages

An IPO-year DAF contribution captures three benefits at once:

1. Highest marginal bracket. Deduction at 37% federal (+ state) for IPO-year income is worth 40-47% per dollar.

2. Capital gains avoidance. Donated appreciated stock never triggers capital gain recognition.

3. Lockup liquidation. If lockup prevents selling post-IPO shares, donating some to DAF is an alternative path to non-retaining the position.

The math for a senior IC with $4M AGI and $500K appreciated stock donation:

• Deduction at 37% federal + 13.3% CA = 50.3% marginal
• Tax savings: $500K × 50.3% = $251,500
• Capital gain avoided: $440K × 23.8% federal + 13.3% CA = $164,000
• Total tax savings: $415,500 on a $500K donation

Effective cost of the charitable gift: $84,500 for $500K of giving power.

Timing with RSU vest cliff

For pre-IPO employees with double-trigger RSUs:

• Before IPO: RSUs are not yet vested for tax (second trigger hasn’t fired)
• At IPO: All time-vested RSUs become taxable ordinary income; shares move to taxable brokerage
• Post-IPO: Shares must be held 12+ months for long-term qualifying donations

For IPO-year giving:

• Cash-only giving in IPO year (60% AGI limit) works for immediate tax benefit
• Stock donations may need to wait 12 months post-IPO for long-term treatment
• Or donate pre-IPO-vested stock from pre-lockup vests (rare, requires 83(i) election or early-stage scenarios)

Most IPO-year DAF giving is either cash (using 60% limit) or waits until year 2 post-IPO for full long-term stock treatment.

Multi-year stacking

For a taxpayer with recurring RSU income, a DAF strategy typically spans years:

• Year 1 (peak income): Large DAF contribution, use all 30% appreciated-stock limit
• Year 2-5: Additional contributions as new tranches hit 1-year holding period
• Year 6+: Steady-state giving from DAF balance

The DAF holds the balance invested. A $2M DAF balance earning 7% annually can support $140K/year of perpetual grants if structured as an endowment.

Alternative: direct gifts to charities

Donating directly to a charity instead of to a DAF has pros and cons:

Direct:

• Same tax benefit (deduction + capital gain avoidance)
• Money goes to charity immediately
• No ongoing administrative relationship

DAF:

• Same upfront tax benefit
• Donor retains advisory role on grants
• Can sprinkle across many charities over years
• Investment growth while balance held

For taxpayers who know exactly where they want the money to go and can handle the administrative overhead of direct gifts (verifying 501(c)(3), getting receipts, etc.), direct gifts work. For taxpayers who want flexibility in timing and distribution, DAFs are cleaner.

Frequently asked

What’s the minimum to open a DAF? Varies by sponsor. Fidelity Charitable: no minimum contribution, $5K suggested first grant. Schwab Charitable: $5K minimum account. Vanguard Charitable: $25K minimum. Community foundations: often $10K-$25K.

Can I donate pre-IPO private stock to a DAF? Most national DAF sponsors (Fidelity, Schwab, Vanguard) don’t accept pre-IPO private stock. Some community foundations and specialty DAFs do. Valuation is the complicating factor: an independent valuation is typically required.

Does §6501 statute apply to the deduction? The 3-year assessment period applies. Keep DAF acknowledgment letters and brokerage transfer records permanently, the IRS can audit a later year and look back at the deduction.

Can I donate unvested RSUs? No. You can only donate stock you own. Unvested RSUs are contingent and can’t be transferred.

What about the 60%/30% split strategy? You can combine cash contributions (60% AGI limit) and appreciated stock (30% AGI limit) in the same year. A taxpayer with $4M AGI can donate up to $2.4M cash and $1.2M appreciated stock, giving $3.6M in deductible contributions that year.
