Donor advised fund contributions
What You Can Contribute, How the Process Works, and What to Expect
You’ve decided to contribute to your DAF. You know the tax math. You know the timing makes sense. Now: what exactly do you do?
The answer depends on what you’re contributing – cash or appreciated securities – and the process for each is more straightforward than most donors expect. This article walks through every step with enough specificity that you can either execute it yourself or hand it to your financial advisor and say, “This is what I want to do.”
What you can contribute
DAF sponsors accept several types of contributions, each with different tax treatment and processing requirements.
Cash. The simplest contribution. Transferred via check, wire, or electronic transfer (ACH). Cash contributions are deductible up to 60% of adjusted gross income (AGI). For most donors, the process is familiar and requires no special coordination.
Publicly traded securities. This is the primary contribution vehicle for high-net-worth donors – and the strategy that delivers the greatest tax benefit. Securities are contributed via a DTC (Depository Trust Company) transfer from your brokerage to the DAF sponsor. The deduction is based on fair market value, up to 30% of AGI. The critical advantage: no capital gains tax is triggered on the appreciation. As covered in The tax case for contributing stock instead of cash to a DAF of this series, this single difference – contributing the shares directly rather than selling them and donating the proceeds – can save thousands of dollars annually in avoided federal and state taxes. The shares must be held longer than one year to qualify for the full fair market value deduction. Short-term holdings (held one year or less) are deductible only at cost basis.
Other eligible assets. Many DAF sponsors also accept mutual fund shares (transfer may take longer than individual stocks), and some accept certain privately held assets, real estate, and cryptocurrency. Acceptance and processing requirements vary by sponsor – check with yours before initiating a transfer of non-standard assets.
For most donors in the $2M–$10M net worth range, publicly traded stock with significant unrealized gains is the primary contribution vehicle. The remainder of this article focuses on the cash and stock contribution processes in detail.
Contributing cash
Cash contributions are straightforward and familiar to most donors.
Methods: Check, wire transfer, electronic transfer (ACH), or in some cases credit card. Note that credit card contributions don’t qualify as appreciated asset contributions – they’re treated the same as cash.
Contribution date: The date the funds are received by the DAF sponsor, not the date you initiate the transfer. For wire transfers, this is typically same-day. For ACH transfers, allow 1–3 business days.
Documentation: The sponsor issues a written acknowledgment confirming the amount and date received. This acknowledgment is the substantiation you need for your tax records.
One note under current rules: the One Big Beautiful Bill Act (Public Law 119-21) introduced a 0.5% AGI floor on charitable deductions beginning in 2026. For a household with $450,000 in AGI, the first $2,250 in total charitable contributions for the year is not deductible. This floor applies to all charitable contributions combined – not per contribution – and applies whether you contribute cash, securities, or both.
Contributing publicly traded stock – Step by step
For donors contributing appreciated stock – the strategy that captures both the charitable deduction and the avoided capital gains tax – the DTC transfer process is the part that feels unfamiliar. It is also more straightforward than most first-time contributors expect. Here are the five steps.
Step 1: Identify the right shares
Look for holdings with the greatest unrealized appreciation – these deliver the most tax benefit. Prioritize long-term holdings (held more than one year), since only long-term holdings qualify for the full fair market value deduction.
If you hold multiple lots of the same security, identify the specific tax lots with the lowest cost basis. Your brokerage can generate an unrealized gains report sorted by lot, making the selection straightforward. For a donor like David Williams – whose RSU grants carry a cost basis of approximately $18,000 on a position currently worth $62,000 – the shares with the lowest basis represent an ideal candidate for contribution.
Step 2: Contact your DAF sponsor
Notify your DAF sponsor that you plan to contribute securities. Most sponsors have a dedicated securities contribution page or form on their website.
Provide the sponsor with three pieces of information: the ticker symbol, the number of shares, and the name and DTC number of your brokerage. The sponsor will provide you (or your broker) with their DTC number, account number, and any reference codes needed for the transfer.
Step 3: Initiate the transfer at you brokerage
Contact your brokerage’s transfer department – by phone, online form, or through your financial advisor. Request a DTC transfer of the specified shares to the DAF sponsor’s account.
Provide the brokerage with the sponsor’s DTC number, account number, and any reference information. Specify which tax lots to transfer – this is critical for maximizing the tax benefit, because contributing the lowest-basis lots generates the largest avoided capital gain.
Step 4: Allow time for settlement
DTC transfers typically take 3–7 business days, though some brokerages may take up to 10 days.
The contribution date – the date that determines the deduction year and the fair market value for the deduction – is the date the shares are received by the sponsor, not the date the transfer is initiated. This distinction matters for year-end contributions: initiate the transfer no later than mid-December to ensure settlement by December 31. This is the single most common logistical pitfall for stock contributors.
For spring and mid-year contributions, there is no deadline pressure – one of the practical benefits of contributing earlier in the year, as discussed in Charitable giving + tax deductions and When to fund a donor advised fund of this series.
Step 5: Confirm and document
Once the transfer settles, the DAF sponsor issues a written acknowledgment confirming the contribution. The acknowledgment includes the number of shares, the date received, and the fair market value on that date.
Retain this acknowledgment for your tax records – it is the substantiation required for the charitable deduction. Your year-end DAF statement will also reflect the contribution.
Deduction limits and carryforward
The IRS sets AGI-based limits on how much you can deduct in a single year, depending on what you contribute.
Cash contributions: Deductible up to 60% of AGI.
Appreciated securities (held more than one year): Deductible up to 30% of AGI at fair market value.
For a household with $450,000 in AGI, the 30% limit means up to $135,000 of appreciated stock can be deducted in a single year – well above a typical $62,000 contribution. Most donors in this profile will not approach the ceiling.
If a contribution does exceed the limit in a given year, the unused deduction can be carried forward for up to five additional years. Carryforward contributions remain subject to the 0.5% AGI floor in the year they are ultimately deducted, per the One Big Beautiful Bill Act rules.
One important nuance: short-term holdings (held one year or less) are deductible only at cost basis, not fair market value. This makes short-term holdings significantly less tax-efficient to contribute. For maximum benefit, contribute shares you have held for more than one year.
Common questions
First-time stock contributors tend to have the same set of practical questions. Here are the most frequent.
What if the stock price changes during the transfer?
The deduction is based on the fair market value on the date the sponsor receives the shares, not the date you initiate the transfer. During the 3–7 day settlement window, the price may move. For a spring or mid-year contribution with no deadline pressure, this is rarely a significant concern. If a particular position is volatile and the timing matters, you and your advisor can plan accordingly.
Can I contribute mutual fund shares?
Yes. Most DAF sponsors accept mutual fund shares, though the transfer process may take longer than individual stocks because mutual fund shares are not settled through the DTC system.
What about restricted stock or stock options?
Shares subject to selling restrictions generally cannot be contributed to a DAF. Vested RSUs that have been released and are freely tradeable are eligible – and are one of the most common contribution types for donors with equity compensation. Consult with your legal counsel for shares with any restrictions.

Is there a minimum contribution?
Minimums vary by sponsor. Some require a minimum initial contribution (often $5,000–$25,000), while others have no minimum. Subsequent contributions may have lower or no minimums. Check with your sponsor before initiating.
What documentation do I need for my tax return?
The sponsor’s written acknowledgment is the primary documentation. For securities contributions exceeding $5,000, you may also need a qualified appraisal – though publicly traded securities with readily available market prices are generally exempt from the appraisal requirement (IRS Publication 526). Consult your CPA for specifics.
Putting it together: The Williams contribution
David Williams identifies a position in his stock – RSU shares with a cost basis of approximately $18,000 and a current fair market value of $62,000, representing $44,000 in unrealized gains.
On Monday, David contacts his DAF sponsor and receives the sponsor’s DTC transfer instructions the same day.
On Tuesday, he calls his brokerage and requests a DTC transfer of the specified shares, providing the sponsor’s DTC number and account information. He specifies the tax lots with the lowest cost basis.
The transfer settles the following Monday – five business days.
The sponsor issues an acknowledgment confirming receipt of the shares at $62,000 fair market value. David’s tax file now contains one document that substantiates a $62,000 deduction and documents $44,000 in avoided capital gains – approximately $10,450 in avoided federal and state taxes at their combined 23.75% rate.
The entire process required two contacts (sponsor and brokerage), took less than 30 minutes of active time, and settled in under a week.
The process of contributing to a DAF – whether cash or appreciated securities – is more straightforward than most donors expect. The stock transfer, which is the unfamiliar part for most first-time contributors, involves two contacts and a few days of settlement time. If you have been holding off because the process felt complicated, this is the article to bookmark or share with your financial advisor.
As discussed in Contribute now grant later, contributing and granting are separate decisions – you don’t need to have your grant recipients selected before contributing. And the earlier in the year you contribute, the sooner the contributed assets can begin growing tax-free, increasing the total value available for future grants.
Donating company stock to a donor advised fund in this series covers the specific considerations for contributing employer stock – including RSUs, vesting schedules, and the additional planning involved when the stock you’re contributing is from your employer. Article 11 walks through what to expect during your first 90 days with a funded DAF, including allocation selection and your first grant requests.
