Donating Startup Stock: Donor-Advised Funds and Charitable Strategies

Founders, employees and investors who hold highly appreciated startup shares have a powerful charitable option: donating the shares rather than cash. Done correctly and at the right time, a donation can generate a charitable deduction for the value of the shares and avoid capital gains tax on the appreciation.

Donor-advised funds, known as DAFs, have become a popular way to do this, and movements such as Pledge 1% have encouraged founders to commit equity to charity early. This guide explains how donating startup stock works in the US, the key rules, and common mistakes.

1. Why Donate Shares Instead of Cash

• Avoid capital gains tax on the appreciation, since the charity or DAF, not the donor, sells the shares.
• Deduct the fair market value of long-term appreciated shares when given to a public charity or DAF, subject to limits based on income.
• Give more for the same after-tax cost compared with selling shares and donating the proceeds.

2. How Donor-Advised Funds Work

1. You contribute shares to a DAF account with a sponsoring organisation.
2. You typically receive a tax deduction in the year of the contribution.
3. The sponsor sells the shares when possible, often at a liquidity event.
4. You recommend grants to charities over time.

Not every DAF sponsor accepts private company stock. Some specialise in complex assets and have experience handling startup shares.

3. Key Rules to Know

• Holding period. Shares generally need to have been held for more than one year to deduct their full fair market value.
• Deduction limits. Deductions for appreciated property given to public charities and DAFs are generally limited to a percentage of adjusted gross income, with carry-forward of excess for several years.
• Qualified appraisal. Donations of private company stock valued above $10,000 generally require a qualified independent appraisal.
• Timing before a sale. If shares are donated after a sale is effectively certain, such as after a binding agreement is signed, tax authorities may treat the gain as the donor's. Donate well before a deal is finalised.
• Transfer restrictions. Company consent or rights of first refusal may apply. See estate planning with private shares.

4. Other Charitable Structures

• Charitable remainder trusts, which can provide an income stream to the donor with the remainder going to charity.
• Private foundations, offering more control but lower deduction limits and more administration.
• Company-level commitments, such as reserving a percentage of equity for charity through initiatives like Pledge 1%.

5. QSBS Considerations

Shares that qualify for the QSBS exclusion may already be eligible for tax-free gains on sale. Donating them provides a deduction but gives up that exclusion. The best choice depends on the individual's tax position and charitable goals. See QSBS explained.

6. Common Mistakes

• Donating after a sale agreement is signed.
• Skipping the qualified appraisal.
• Choosing a DAF sponsor that cannot hold private shares.
• Ignoring company transfer restrictions.
• Donating shares held for less than one year and expecting a full market-value deduction.
