At a recent dinner with friends, the topic of giving came up. Good people, doing good things.

When I asked if anyone was using a donor-advised fund (DAF), many hadn't heard of it.

That's not unusual. Donor-advised funds have been around for decades, but they're still one of the most overlooked tools available to people who give. If you're philanthropic and you're also a high earner: a physician, a tech professional, someone who owns investments that have grown over the years, it's worth understanding how they work.

The TL;DR:

• A donor-advised fund is a tax-advantaged charitable giving account: contribute now, get an immediate deduction, and grant to charities on your own timeline.
• Donating appreciated investments through a DAF is almost always more tax-efficient than writing a check. You skip the capital gains tax and deduct the full market value.
• DAFs simplify giving: one account, one tax receipt, and the flexibility to support any qualified charity, including smaller ones that can't accept stock directly.
• Providers vary on minimums, fees, and accepted asset types. The right fit depends on your balance and how you plan to use it.

What Is a Donor-Advised Fund?

A donor-advised fund (DAF) is a charitable giving account sponsored by a nonprofit organization. You make a contribution, claim an immediate tax deduction, and then recommend grants to your chosen charities over time, on your schedule, at your pace.

Think of it as a charitable account with meaningful tax advantages built in. Your money can stay invested and grow tax-free until you're ready to send it to the organizations you care about.

The Case for Donating Stock, Not Cash

This is where most people leave real money on the table.

If you own investments that have grown in value such as stocks, mutual funds, ETFs, and you sell those shares to write a check to charity, you first owe capital gains tax on the profit. Depending on your situation, that can be up to 23.8% federally on long-term gains. You donate what's left.

But if you contribute those appreciated shares directly to a donor-advised fund, you skip the capital gains tax entirely. The full market value goes into the account. You get a deduction based on that full amount, not the after-tax proceeds.

Your charity receives more. You get a larger deduction. Nobody pays the capital gains. It's one of the rare situations in tax planning where doing the efficient thing also means doing the more generous thing.

The same logic applies during portfolio rebalancing. Rather than selling an appreciated position to shift into a different allocation and triggering a capital gain, you can donate those shares to your DAF and use cash you'd already earmarked for charity to make the replacement purchase. You accomplish the rebalance without the tax bill.

(Note: The IRS limits how much of this deduction you can take in a single year based on your income. Your tax advisor can walk you through the specifics for your situation.)

Deduct Now, Give Later

Another practical benefit: DAFs separate the timing of your tax deduction from when you actually distribute the funds.

In a high-income year (a large bonus, a practice transition, a particularly strong investment year), you can make a substantial contribution to your DAF and take the deduction when it's most valuable.

This is useful for anyone whose philanthropic goals are still evolving, or who simply doesn't want to make rushed end-of-year charitable decisions just to capture a tax benefit.

One Account, Many Charities

If you give to multiple organizations each year, a DAF eliminates the paperwork. Instead of tracking receipts from a dozen different charities at tax time, you have one tax receipt from the DAF covering everything.

It's also a practical solution for giving to smaller organizations that can't accept stock transfers directly. You contribute appreciated shares to your DAF; the DAF liquidates them tax-free and issues a cash grant to the charity. The organization receives cash; you've still avoided the capital gains.

Choosing a Provider

DAFs are offered through many institutions, and the differences matter less than most people expect at first. The major national providers, Fidelity Charitable, Schwab Charitable, and Vanguard Charitable, are well-established and handle a wide range of asset types.

Fidelity and Schwab have no minimum initial contribution, which makes them accessible if you're just getting started or plan to use the DAF primarily as a convenience vehicle. Vanguard requires a $25,000 minimum to open an account but offers some of the lowest underlying investment costs in the industry. Newer platforms like Daffy take a different approach with a flat monthly subscription fee rather than a percentage of assets, which can make more sense as balances grow.

The right provider depends on your balance, how actively you plan to grant, and how you prefer to manage accounts. A fee-only financial advisor can help you think through which structure fits.

Is a DAF Right for You?

If charitable giving is already part of your financial picture, and especially if you own appreciated investments, a donor-advised fund is worth a conversation. The mechanics are straightforward, setup is often done entirely online, and the tax benefits can be meaningful.

If you're still writing checks, you may be making giving more expensive than it needs to be. The good news is that's easy to change.
