Tax Smart Charitable Giving : A Year End Guide for 2025

Most people think of charitable giving as a simple transaction: you write a check to a cause you care about, and at tax time the deduction helps reduce your bill.

Straightforward?  Not exactly.

The tax code gives us a lot more room to optimize charitable gifts than most taxpayers realize.  When you understand your options, charitable giving becomes one of the most powerful tools in your tax-planning toolkit. You can support the organizations you care about and meaningfully reduce your lifetime tax burden, especially as your income fluctuates throughout retirement.

In today’s post, I’ll walk through the most valuable charitable tax strategies we use with clients at Three Oaks Wealth. These are the same methods we apply in real planning engagements with people nearing or in retirement, many of whom want to give but also want to avoid unnecessary taxes.

 

The Standard Deduction Changed the Game

First off, before 2018 most taxpayers itemized deductions.  Now, the majority take the standard deduction because it’s simply larger.  For 2025, the standard deduction will be:

• $31,500 for married couples filing jointly
• $15,750 for single filers

When you take the standard deduction, your charitable contributions typically provide no additional tax benefit—unless your total itemized deductions exceed the standard deduction.

For many retirees, they don’t.  That’s why simply writing a check to charity is often the least efficient way to give from a tax perspective.

To get around this problem, we often use a strategy called bunching.

 

“Bunching” Charitable Gifts: Claim Big Deductions When They Help the Most

Bunching involves giving several years’ worth of charitable contributions at once, so your itemized deductions exceed the standard deduction in that year. In off-years, you take the standard deduction as normal.

Here’s what that might look like:

• Suppose you give $10,000 to charity each year.
• Rather than giving $10,000 in 2025, 2026, and 2027, you “bunch” and give $30,000 in 2025.
• In 2025, your itemized deductions exceed the standard deduction—so you get a substantial tax break.
• In 2026 and 2027, you revert to the standard deduction.

Your favorite charities still receive your support—you just do it in a way that actually results in a tax benefit.

This becomes even more effective when paired with a donor-advised fund.

 

Donor-Advised Funds (DAFs): A Flexible, High-Impact Planning Tool

A donor-advised fund (DAF) lets you:

1. make a charitable contribution now,
2. receive the full deduction this year, and
3. grant the money to charities gradually over time.

Think of a DAF as your own charitable giving account. You contribute assets, take the deduction immediately, invest the dollars inside the fund, and then direct grants when you’re ready.

DAFs offer two significant tax advantages:

• You can contribute appreciated stock or ETFs

This is a big one. When you donate appreciated investments directly:

• You avoid capital gains tax
• You receive a deduction for the full fair market value
• The charity receives the entire amount, not the after-tax remainder

If you have highly appreciated shares in a taxable account—and many of our clients do after the last decade of market growth—this strategy is often far more tax-efficient than donating cash.

• You can time deductions strategically

Clients often use DAFs in high-income years—maybe after:

• selling a business or rental property
• realizing large capital gains
• completing a Roth conversion
• receiving an unexpected bonus

You front-load gifts in the year the deduction matters most, then support charities slowly over time. That combination can significantly reduce lifetime taxes.

 

Qualified Charitable Distributions (QCDs): The Most Tax-Efficient Way for Retirees to Give

Once you hit age 70½, you gain access to what qualified charitable distributions (QCDs).

A QCD lets you transfer up to $108,000 per year directly from your IRA to a qualified charity.  The benefit?

The distribution is never taxed.  Here’s why that matters:

• It satisfies some or all of your required minimum distribution (RMD)
• It is excluded from your taxable income
• It does not require itemizing deductions
• It may reduce the taxation of Social Security benefits
• It may reduce Medicare IRMAA surcharges

That last item is especially important. Many retirees are shocked by IRMAA charges—which can add thousands per year to Medicare premiums. Because QCDs avoid showing up on your tax return as income, they can keep you in a lower IRMAA bracket.

For charitably inclined retirees, QCDs are simply a home run.

Two quick notes:

1. QCDs must come from an IRA—not a 401(k). You can roll money from a 401(k) to an IRA if needed.
2. QCDs cannot go to donor-advised funds. They must go directly to the charity.

If you’re over 70½ and giving to charity, QCDs should be the first tool you evaluate.

 

Giving Appreciated Assets: Still One of the Most Powerful Tax Moves

Even outside of donor-advised funds, donating appreciated securities—stocks, ETFs, mutual funds, real estate, or even crypto—can lead to significant tax savings.

For assets you’ve held more than a year:

• You eliminate capital gains tax
• You receive a deduction equal to the full market value (up to 30% of AGI for appreciated property)

Let’s say you own $40,000 of an ETF with a cost basis of $10,000. If you sold it, you’d owe capital gains tax on $30,000 of gains.

But if you donate it to charity (or to a DAF):

• You avoid the gain entirely
• You receive a deduction for the full $40,000

This is especially valuable for clients with large taxable investment accounts that have grown substantially over time.

 

Charitable Remainder Trusts (CRTs): Giving While Securing Income for Yourself

For higher-net-worth families or people with highly appreciated assets, we sometimes recommend a charitable remainder trust (CRT).

How it works:

1. You contribute appreciated assets into the trust.
2. The trust sells the assets without triggering capital gains tax.
3. The trust pays you (or someone else) an income stream for life or a term of years.
4. When the trust ends, the remainder goes to charity.

You also receive a partial charitable deduction in the year you fund the trust.

A CRT lets you diversify a concentrated position, avoid a massive capital gains tax bill, and create a lifetime income stream—while still supporting charity. It doesn’t fit every scenario, but when it fits, it fits extremely well.

 

Charitable Planning Works Best When Integrated Into a Bigger Strategy

Standalone charitable gifts are great. But charitable planning is even better—because it ties your giving decisions into the rest of your financial life.

At Three Oaks, we often integrate charitable strategies with:

• Roth conversion schedules
• Social Security timing
• Tax-efficient withdrawal plans
• Capital gains harvesting
• Estate planning and legacy goals
• IRMAA management
• Large one-time income events

Many clients come in saying, “I want to give to charity, but I don’t want to do it inefficiently.” Once we layer charitable planning into the broader financial picture, the result is usually:

• More predictable retirement income
• Lower tax bills
• Reduced Medicare premiums
• Less capital gains exposure
• And more dollars ending up with the charities

That’s the trifecta: do good, reduce taxes, and increase financial resilience.

 

Charitable Giving Should Be Strategic

Most people give to charity because it feels good and because they want to support something bigger than themselves. The tax benefits are secondary.

But when you combine charitable intent with thoughtful tax planning, you can double—or even triple—the impact of every dollar you give.

The bottom line:

• If you’re over 70½: Explore QCDs first.
• If you have taxable investments: Consider donating appreciated assets.
• If you want long-term flexibility: Use a donor-advised fund.
• If you itemize only occasionally: Use bunching strategies.
• If you have a large one-time tax event: Front-load charitable gifts strategically.

Charitable giving is one of the few areas where the tax code actually rewards you for doing something beneficial. With a little planning, you can make your philanthropic goals and financial goals work together rather than compete with one another.
