Donating company stock to a donor-advised fund: RSUs, vesting schedules, and what to know before you contribute

If your compensation includes restricted stock units, you’re sitting on one of the most tax-efficient assets you can contribute to a donor-advised fund. The shares you received through RSU grants – once vested and held for more than one year – can be contributed directly, capturing a fair market value deduction while eliminating capital gains tax on all post-vesting appreciation.

The process is the same DTC (Depository Trust Company) transfer covered in Donor advised fund contributions of this series. The planning, however, involves a few additional considerations that are specific to employer stock: which tranches are eligible, how vesting dates interact with the one-year holding period, whether your company’s blackout windows affect the timing, and how contributing employer stock serves double duty – funding your charitable giving while reducing concentration in a single position.

How RSUs create a charitable planning opportunity

When RSUs vest, the fair market value at vesting is taxed as ordinary income – this is the income event most executives are familiar with. After vesting, the shares are yours. Any appreciation beyond the vesting price is a capital gain.

If you sell those shares, you pay capital gains tax on the post-vesting appreciation. If you contribute them directly to a donor-advised fund, you don’t.

The charitable deduction is based on the fair market value at the time of contribution – not the vesting price and not the original cost basis. For a hypothetical donor whose RSU grants vested at approximately $18,000 in value and are now worth $62,000, the $44,000 in post-vesting appreciation is the charitable planning opportunity. Contributing these shares directly avoids approximately $10,450 in combined federal and state capital gains taxes (15% federal long-term capital gains rate + 3.8% net investment income tax + 4.95% Illinois state tax = 23.75% combined rate on avoided gain, per IRS Topic 409 and Topic 559).

That’s the same charitable donation to the same organizations – just routed through a different asset, with a $10,450 reduction in taxes owed. The math behind this comparison is covered in detail in The tax case for contributing stock instead of cash to a DAF of this series.

The One-Year Holding Period: Why It Matters for RSU Contributors

This is the most important planning detail for RSU contributors. To receive a deduction at full fair market value, the contributed shares must be held for more than one year from the vesting date – not the grant date. Shares held for one year or less are deductible only at cost basis, which for RSUs is the fair market value at vesting.

What does that mean in practice? A recently vested RSU tranche contributed within the first year would generate a deduction equal to the vesting price – with no capital gains benefit, since there’s no long-term gain to avoid. You’d be contributing shares and receiving a deduction for the same amount you already paid income tax on at vesting. The charitable contribution still counts, but the tax advantage of donating appreciated stock disappears.

The planning implication is straightforward: review your vesting schedule and identify tranches that have passed the one-year mark. For donors with rolling vesting schedules – quarterly or annual vesting over four years, for example – some tranches will be eligible while others won’t. Your brokerage’s unrealized gains report, sorted by acquisition date and lot, is the tool that makes this easy to see. This holding period rule is documented in IRS Publication 526 and Publication 561.

Blackout windows, trading policies, and compliance

Company stock contributions are subject to the same insider trading policies and trading window restrictions that apply to sales. If you’re an officer, director, or designated insider at a publicly traded company, a few compliance steps apply before you initiate a DTC transfer to a donor-advised fund.

Pre-clearance. Most public companies require officers and certain employees to obtain pre-clearance before any transaction involving company stock – including charitable transfers. Check with your compliance department or legal counsel before initiating a contribution.

Blackout periods. Companies typically impose trading blackouts around earnings announcements and other material events. A DTC transfer to a donor-advised fund is a disposition of company stock and is generally subject to these restrictions. If you’re planning a spring contribution, check your company’s blackout calendar and work backward from the window dates.

10b5-1 plans. Some executives use Rule 10b5-1 trading plans to automate stock transactions on a predetermined schedule. A DAF contribution can potentially be incorporated into a 10b5-1 plan – consult your securities attorney if this applies to your situation.

Company-specific policies. Some companies have additional policies around stock gifting, transfer thresholds, or reporting requirements. The HR or equity compensation team is the right first contact.

These compliance steps aren’t barriers – they’re standard procedures your company already has in place for any stock transaction. Adding a DAF contribution to the process is straightforward once you know whom to contact and when the next open trading window falls.

Concentration risk and the dual benefit

For executives with large RSU positions, contributing company stock to a donor-advised fund serves two purposes simultaneously: funding charitable giving and reducing portfolio concentration.

When a significant portion of your net worth is in a single company’s stock – especially your employer’s stock – you’re exposed to company-specific risk that diversification would reduce. The standard advice is to diversify, which usually means selling shares and paying capital gains tax on the appreciation. A DAF contribution achieves the same diversification effect without the tax cost.

The contributed shares leave your portfolio. No capital gains tax is triggered. And the charitable deduction offsets other income. For a hypothetical donor contributing $62,000 of company stock each year, that’s not just a charitable strategy – it’s also the most tax-efficient way to systematically reduce a concentrated position. Over five years, that’s $310,000 of employer stock removed from the portfolio with no capital gains taxes paid and approximately $52,250 in cumulative tax savings.

Your financial advisor has likely already raised the topic of concentration risk. This approach gives you a way to act on that advice while simultaneously funding the charitable giving you’re already doing.

Coordinating with your financial advisor

This article has covered the tax mechanics, the holding period, compliance requirements, and the concentration benefit. The final step is bringing a specific plan to your advisor.

What to bring to the conversation:

Your vesting schedule, showing grant dates, vesting dates, and lot-level cost basis. Your unrealized gains report sorted by acquisition date. Your company’s blackout window calendar. And the name and contact information of your compliance or equity compensation contact.

The questions to ask:

Which tranches have cleared the one-year holding period? What’s the estimated tax savings at our combined rate? Should we incorporate the contribution into an existing 10b5-1 plan? And how does this interact with any other planned stock sales or rebalancing this year?

For donors making quarterly estimated tax payments, there’s an additional question: how does the timing of the contribution affect Q2 and Q3 estimates? That topic is covered in detail in Donor Advised Funds and Estimated Tax Payments of this series.

Worked example: Identifying the right tranche

A hypothetical donor reviews his RSU vesting schedule with his financial advisor. He has four tranches:

Tranche 1: Vested March 2024. Cost basis $15,000, current FMV $58,000. Eligible (held more than one year, $43,000 gain).

Tranche 2: Vested September 2024. Cost basis $17,000, current FMV $61,000. Eligible (held more than one year, $44,000 gain).

Tranche 3: Vested March 2025. Cost basis $19,000, current FMV $63,000. Eligible (held more than one year, $44,000 gain).

Tranche 4: Vested September 2025. Cost basis $21,000, current FMV $64,000. Not yet eligible (held less than one year as of spring 2026).

His advisor identifies Tranche 1 as the optimal candidate: longest holding period, lowest cost basis, largest gain. The donor checks with his company’s compliance team and confirms the next open trading window. He initiates the DTC transfer during the window, following the five-step process from Donor advised fund contributions.

The contribution settles in five business days.

Result: $58,000 deduction. $43,000 in avoided capital gains. Approximately $10,200 in combined federal and state tax savings (23.75% of $43,000). And a meaningful reduction in his concentrated employer stock position.

Next steps

Contributing company stock to a donor-advised fund is the same DTC transfer process described in Donor advised fund contributions – with an additional planning layer for holding periods, compliance windows, and concentration management. If your compensation includes RSUs or other equity grants, the conversation with your financial advisor is specific: “Which of my vested tranches have cleared the one-year holding period, and what’s the tax savings if we contribute those shares directly instead of selling them?”

That conversation, combined with a quick check with your compliance team, is all that stands between you and the most tax-efficient charitable contribution available to equity compensation recipients.

Donor Advised funds and estimated tax payments in this series covers how the timing of your contribution can affect your quarterly estimated tax payments – a particularly relevant consideration for spring and mid-year contributions.
