Charitable Bunching in 2026: Give Big, Skip a Few Years, Give Big Again

Bunching means giving three or four years of planned charitable gifts in a single tax year, itemizing that year, then taking the standard deduction in the years you skip. You give the same total. You only change the timing. For a couple at $300,000 of income who give $10,000 a year, bunching five years into one recovers about $6,000 of deduction that the annual approach forfeits, and it does so without giving a dollar more.

The strategy is not new, but 2026 gave it a second engine. The One Big Beautiful Bill Act added a 0.5% AGI floor to the itemized charitable deduction, and that floor is charged every single year. Spread your giving evenly and you pay it five times. Concentrate it and you pay it once. If you have been giving the same steady amount every December for a decade, this is the year the habit is worth re-examining.

Why does bunching save money at all?

Two separate reasons now, and they stack. The older one is the standard deduction. In 2026 a married couple filing jointly gets $32,200 automatically. Charitable gifts only produce a benefit to the extent your itemized deductions beat that number, so a household with $12,000 of mortgage interest and state taxes plus $10,000 of giving lands at $22,000 and takes the standard deduction anyway. The giving produced nothing. Concentrate five years of gifts into one and that year totals $62,000 of itemized deductions, which clearly beats $32,200.

The newer reason is the floor. Only giving above 0.5% of AGI is deductible, and the threshold resets each January. That is a toll you pay once per year no matter how small your gift, so the fewer giving years you have, the fewer times you pay it. I explain the floor itself in more depth in my breakdown of the 2026 charitable deduction floor.

What does the cadence actually look like?

Here is the same $50,000 of total giving over five years, arranged two ways. A couple with $300,000 of AGI, so their annual floor is $1,500.

Hypothetical illustration only, not a projection of actual results. Figures assume the stated inputs and returns, which are not guaranteed; your outcome depends on your contributions, investment returns, tax rates, and time horizon. Past performance does not guarantee future results.

That $1,900 is the floor effect alone. For a household that was not clearing the standard deduction in the even-giving years, the standard-deduction effect is usually larger still, and the two add together. Neither one requires giving a single extra dollar.

How do you bunch without leaving charities in a gap?

Use a donor-advised fund. You contribute the full multi-year amount in the bunch year and take the deduction then, but the money does not have to leave the fund on the same schedule. You recommend grants to your charities annually, exactly as you always have. From the organization's side, nothing changed: the same check arrives in the same month. From the tax side, you took one large deduction instead of five small ones that mostly evaporated.

This is the part people miss when they first hear about bunching. The objection is usually "my church needs the money every year," and it is a fair objection to bunching done without a fund. With one, the concern disappears. I covered how these accounts work and what to watch on fees in my guide to donor-advised funds for high earners.

Two mechanical notes. Fund the account with appreciated stock rather than cash whenever you hold a position with a large gain, because you skip the capital gains tax and still deduct fair market value. And know that gifts to a donor-advised fund do not qualify for the new $1,000 or $2,000 non-itemizer deduction, so the fund is an itemizer's tool by design.

Which year should you bunch into?

Pick your highest-income year in the window, because a deduction is worth your marginal rate and nothing else. A $50,000 deduction saves $16,000 at 32% and $11,000 at 22%. The same gift, $5,000 apart in value, decided entirely by which year you put it in.

In practice the best candidates are years with a one-time income event: a large RSU vest, a bonus, a business sale, an exercise of stock options, or a deliberate Roth conversion. Pairing a bunched gift with a conversion is a particularly clean combination, because the deduction absorbs income you chose to create. You can test how much you could convert in a bunch year before the next bracket and size the gift to match.

One caution in the other direction. A larger gift raises your floor only slightly, but it can run into the 60% of AGI ceiling for cash gifts, which the 2026 law made permanent. If you are contemplating a gift near or above 60% of your income, the excess carries forward for five years and the sequencing gets more involved. That is a conversation to have before you fund, not after.

When should you not bunch?

• You are 70½ or older with a traditional IRA. A qualified charitable distribution beats bunching outright. It excludes the gift from income rather than deducting it, so the floor and the 35% cap never apply and it counts toward your required minimum distribution. Lead with QCDs and bunch only what you give beyond them.
• You itemize every year regardless. If your mortgage interest and state taxes already clear $32,200 on their own, the standard-deduction argument does not apply to you. The floor argument still does, so bunching helps, just less.
• The lump sum strains your cash. A deduction returns some fraction of what you give, never all of it. Committing $50,000 to save $1,900 in tax is only sensible if you were always going to give the $50,000. Bunching is a timing decision, not a reason to give more than you planned.
• Your income is about to jump. If next year brings a business sale or a large vest, wait. Bunching into the higher year is worth materially more than bunching into this one.

A workable cadence

For most households I work with, the rhythm ends up looking like this. Fund a donor-advised fund with appreciated stock in a high-income year, sized at three to five years of intended giving. Grant from it annually so the charities notice nothing. Take the standard deduction in the off years and stop tracking receipts. Then repeat when the next high-income year arrives, which is often a vest year, a bonus year, or a conversion year you chose deliberately.

Whether three years or five is right for you depends on your other deductions, your bracket in each year, and how much of the gift can come from appreciated stock instead of cash. Those three inputs are worth actually running rather than estimating, and the comparison is arithmetic.
