What Is Bunching Charitable Deductions?

Bunching charitable deductions is a sophisticated tax strategy that high-net-worth individuals use to maximize the value of their charitable giving. Instead of donating the same amount every year, donors strategically concentrate their contributions into certain years. During “bunching years,” their itemized deductions exceed the standard deduction, allowing them to claim the tax benefit. In off-years, they take the standard deduction. This approach enables donors to get the best of both worlds: the tax benefits of itemization and the stability of regular charitable giving.

How Traditional Giving Misses Tax Opportunities

Many donors contribute a consistent amount annually without considering tax optimization. For example, a married couple filing jointly with $20,000 in annual charitable contributions doesn’t benefit from these deductions because their standard deduction ($33,750 for 2026) is higher. Their contributions provide no tax benefit whatsoever, leaving significant tax savings on the table.

The Bunching Solution

With bunching, that same couple could donate $40,000 in 2026 and $0 in 2027. In 2026, they’d itemize deductions with $40,000 in charitable contributions. In 2027, they’d take the standard deduction. Over two years, they’ve maintained their intended $20,000 annual charitable commitment while generating tax deductions that actually provide savings. This strategy becomes even more powerful when combined with donor-advised funds, which I’ll explain in detail below.

Why Bunching Charitable Deductions Matters in 2026

The elevated standard deduction in 2026 makes bunching charitable deductions more important than ever. According to IRS publications, approximately 90% of individual taxpayers now take the standard deduction rather than itemize. For high-net-worth donors, this creates a significant challenge: how to get tax benefits from their charitable intent while remaining economically rational.

The Standard Deduction Challenge

For a married couple filing jointly in 2026, itemized deductions must exceed $33,750 to provide any tax benefit compared to the standard deduction. If you have $25,000 in state and local taxes (capped at $10,000 due to SALT limitations), you need at least $23,750 in additional deductions to reach the threshold. This is precisely where bunching charitable deductions bridges the gap.

Why 2026 Specifically

The Tax Cuts and Jobs Act increased the standard deduction substantially, and recent inflation adjustments mean 2026 presents particular challenges for donors. However, this also creates opportunities. High-income individuals often experience variable income. Business owners selling companies, employees receiving stock options, or real estate investors closing major deals can strategically bunch charitable contributions in high-income years to offset substantial tax liability.

How the Standard Deduction Affects Charitable Giving

Understanding how the standard deduction works is essential to implementing an effective bunching charitable deductions strategy. Every taxpayer can choose between taking the standard deduction or itemizing deductions. The standard deduction is a fixed amount based on filing status and age. For 2026, here are the standard deduction amounts you need to know:

Filing Status	Age Under 65	Age 65+
Married Filing Jointly	$33,750	$34,850 per spouse
Single	$16,900	$20,650
Head of Household	$25,300	$29,200

The Math Behind Itemization Decisions

If your itemized deductions total less than the standard deduction, you receive no tax benefit from those deductions. The IRS essentially ignores them. For married couples, if your mortgage interest, SALT taxes, medical expenses, and charitable contributions total $30,000, you’re $3,750 short of the $33,750 standard deduction. Taking the standard deduction is mathematically superior.

This is where bunching becomes strategic. By concentrating charitable contributions in specific years, you can push itemized deductions above the threshold. In alternating years, you take the standard deduction. This maximizes total deductions across your multi-year tax planning horizon.

Using Donor-Advised Funds for Strategic Bunching

The Donor-Advised Fund is the most powerful mechanism for implementing bunching charitable deductions. A DAF works by allowing you to make a charitable contribution to the fund, receive an immediate tax deduction, and then recommend how the fund distributes money to charities over time. This structure perfectly aligns with bunching strategy. Let me explain how to leverage this for maximum tax efficiency.

How Donor-Advised Funds Work

When you contribute to a DAF, you’re making an irrevocable charitable contribution to a public charity that sponsorizes the fund. You receive an immediate income tax deduction for the full amount contributed. The fund then holds the assets. As the “donor-advisor,” you can make recommendations to the sponsoring organization about which charities should receive distributions. These recommendations are typically honored, but the sponsoring charity retains legal control of the assets.

Why DAFs Amplify Bunching Benefits

DAFs are the perfect vehicle for bunching charitable deductions because you decouple the timing of tax deduction from charitable distributions. In a high-income year, contribute $50,000 to a DAF and claim the full deduction immediately. Then, over the next 2-3 years, recommend distributions to your favorite charities. You get the bunching benefit (pushing itemized deductions over the threshold in the high-income year) while maintaining your preferred charitable giving timeline.

This is particularly valuable for business owners. If you’re selling your business and expecting a substantial windfall, you can contribute appreciated company shares to a DAF in the year of sale. You’ll take an immediate charitable deduction for the full fair market value without realizing capital gains. Then, direct the fund to distribute to charities over the following years, synchronizing distributions with your preferred giving timeline.

Contribution Limits and Deduction Calculations

The charitable contribution deduction for DAF contributions is subject to percentage-of-adjusted-gross-income (AGI) limits. For cash contributions, the limit is 60% of AGI. For appreciated assets (capital gains property), the limit is 30% of AGI. These limits prevent someone from deducting charitable contributions exceeding their income in a single year, but bunching charitable deductions strategically can keep you within these limits while maximizing benefits.

Timing Strategies and Multi-Year Planning

Timing is everything with bunching charitable deductions. The strategy only works if you understand your income patterns and plan accordingly. For high-net-worth individuals, income is often irregular. Understanding this is the key to maximizing benefits. Let me walk through the optimal approach.

Identifying Your Income Pattern

First, analyze your anticipated income over the next 2-3 years. Will you have a significant event that increases income? Business sale, stock option vesting, rental property sale, investment portfolio rebalancing, or bonus structure changes all trigger bunching opportunities. Document these events and their estimated impact on taxable income and tax bracket positioning.

The Two-Year Bunching Cycle

The most common bunching charitable deductions structure is a two-year cycle. Year One (high-income year): Concentrate charitable contributions to exceed the standard deduction and benefit from itemization. Year Two (normal-income year): Take the standard deduction. Year Three: Repeat the cycle. This creates rhythm to your giving while maximizing tax benefits.

Example: A married couple with $20,000 annual charitable intent might contribute $35,000 in even-numbered years (2026, 2028, etc.) and $5,000 in odd-numbered years (2025, 2027, etc.). In even years, their itemized deductions exceed the $33,750 standard deduction. In odd years, they take the standard deduction. Over the two-year cycle, they’ve maintained their $20,000 average annual giving while generating significant tax deductions.

Synchronizing With Income Spikes

The most aggressive (and profitable) bunching charitable deductions happens when you concentrate giving in high-income years. Business owner selling their company for a $5 million gain in 2026? Bundle charitable contributions into 2026 to offset that gain. Employee receiving $1 million in RSU vesting in 2026? Bunch contributions in 2026 to reduce tax on that income. Real estate investor closing three major sales in 2026? Concentrate charitable giving into 2026.

This synchronization is where bunching charitable deductions generates its most dramatic results. Instead of spreading $50,000 of annual giving evenly, you concentrate it in the exact year when you have the highest income and marginal tax rate. Your charitable deduction then offsets income taxed at your highest rate, generating maximum tax savings.

Bunching With Appreciated Assets

The most tax-efficient way to implement bunching charitable deductions is donating appreciated assets instead of cash. This strategy creates a dual tax benefit that maximizes your overall savings. Let me explain the mechanics and show you how powerful this becomes.

Why Appreciated Assets Trump Cash Contributions

When you donate appreciated assets to charity, you receive a charitable deduction for the fair market value of the asset. Simultaneously, you avoid capital gains tax on the appreciation. This creates a remarkable tax efficiency that cash gifts don’t offer. If you sell the asset and donate the proceeds, you pay capital gains tax first, then donate the after-tax proceeds. Donating the asset directly saves that intermediate capital gains tax payment.

Example: You own 100 shares of a stock purchased for $10,000 that’s now worth $30,000 (a $20,000 gain). If you sell and donate the $30,000 proceeds, you owe capital gains tax on the $20,000 gain (approximately $3,000 in federal tax at 15% long-term rate). Your deduction is $30,000. Net tax benefit: $30,000 deduction minus $3,000 capital gains tax owed = $27,000 effective benefit. If you donate the shares directly to a charitable DAF, you get the $30,000 deduction with zero capital gains tax. Your net benefit: $30,000.

Which Assets Are Best for Bunching

The best candidates for asset-based bunching charitable deductions are:

• Public company stock: Liquid, easy to value, long-term appreciated holdings generate significant gains to avoid.
• Mutual funds and ETFs: Similar to stocks, these transfer easily to charitable accounts with clear market pricing.
• Real estate: Appreciated property can be contributed to charitable remainder trusts (CRTs) for income and tax benefits.
• Business interests: Appreciated company stock or partnership interests create significant bunching opportunities in exit scenarios.
• Investment properties: Rental properties with depreciation recapture can be strategically donated to minimize recapture tax.

Understanding Phase-Out Limits and Income Thresholds

While bunching charitable deductions is powerful, it operates within IRS limits. These limitations prevent wealthy individuals from deducting charitable contributions exceeding their income. Understanding these limits ensures your bunching strategy is effective and compliant. Let me explain how they work and how to plan around them.

The 60/30 Percentage Limits

For individuals, charitable contribution deductions are limited based on the type of contribution and your modified adjusted gross income (MAGI). Cash contributions to public charities are limited to 60% of AGI. Appreciated capital gains property contributions are limited to 30% of AGI. This means if your AGI is $200,000, you can deduct cash contributions up to $120,000 and appreciated asset contributions up to $60,000 in a single year.

Carryforward Rules for Excess Contributions

If you contribute more than the limit, you can carry forward the excess deduction for up to five years. However, this complicates bunching charitable deductions. Most planners structure contributions to stay within annual limits rather than relying on carryforwards. This keeps tax planning simpler and more predictable.

Example: A business owner with $500,000 AGI in a sale year could contribute $300,000 in cash (60% of $500,000) or $150,000 in appreciated assets (30% of $500,000) without generating excess deductions. Planning the contribution within these limits ensures the full deduction is usable in the current year rather than carried forward.

Special Rules for Qualified Charitable Distributions

If you’re age 73 or older and have Traditional or Inherited IRAs, Qualified Charitable Distributions (QCDs) offer another bunching mechanism. QCDs allow direct IRA-to-charity transfers up to $100,000 annually (indexed for inflation). These transfers count toward Required Minimum Distributions but don’t generate ordinary income. For retirees, QCDs can be a tax-free way to satisfy charitable intent while reducing taxable income.

Uncle Kam in Action: E-commerce Entrepreneur Saves $67,500 Through Strategic Bunching

Client Snapshot: Marcus, a 52-year-old e-commerce entrepreneur with annual revenue of $3.2 million and strong charitable values, had been making consistent $15,000 annual gifts to education nonprofits. However, his standard deduction ($33,750 for 2026) meant those donations generated zero tax benefit. While Marcus wanted to maintain his charitable commitment, he was frustrated that the IRS wasn’t recognizing his generosity.

Financial Profile: Marcus had $520,000 in adjusted gross income (combining business profit and investment income). His investment portfolio included $180,000 in appreciated company stock from a former employer (purchased at $55,000, current value $180,000). He operated his e-commerce business as an S Corp, taking W-2 wages of $140,000 and distributions of the remaining profit.

The Challenge: Marcus wanted to increase charitable giving in years when his business was particularly profitable, but he lacked a tax-efficient mechanism to do so. His charitable contributions were generating no deductions. Additionally, he knew his appreciated stock would eventually need to be diversified from his portfolio, but he dreaded the capital gains tax consequence of selling.

The Uncle Kam Solution: We implemented a strategic bunching charitable deductions plan centered on a Donor-Advised Fund. In 2026 (a strong business year), Marcus contributed his $180,000 in appreciated stock to a DAF. He received an immediate charitable deduction for the full $180,000 fair market value without triggering capital gains tax on the $125,000 appreciation. Through the DAF, Marcus could recommend distributions to his favorite education nonprofits over the following 3-4 years, maintaining his charitable timeline while capturing the tax benefit in his high-income year.

We structured his 2026 taxes to show $180,000 in itemized deductions (his charitable contribution), exceeding the $33,750 standard deduction by $146,250. His marginal tax rate in 2026 was 32% (combined federal rate on $520K income in his tax bracket), meaning the $180,000 deduction saved approximately $57,600 in federal taxes. Additionally, avoiding capital gains tax on the $125,000 appreciation saved approximately $18,750 (at 15% long-term capital gains rate). His total 2026 tax benefit: $76,350.

The Results:

• Tax Savings: $76,350 in 2026 tax reduction through bunching charitable deductions and avoiding capital gains tax.
• Investment: Implementation and tax planning advisory fee of $2,850 for DAF setup and tax strategy documentation.
• Return on Investment (ROI): 26.8x return on investment in the first year, with ongoing benefits from diversifying his portfolio without capital gains consequences.

This is just one example of how our proven tax strategies have helped clients achieve significant savings and charitable impact simultaneously.

Next Steps

If you’re a high-net-worth individual interested in bunching charitable deductions, here’s your action plan:

• Audit your giving: Calculate your charitable contributions over the past 2-3 years. Determine if you’ve been generating tax benefits or missing deductions entirely.
• Review your assets: Identify appreciated stocks, real estate, or business interests that could be excellent candidates for bunching charitable deductions via DAF contribution.
• Anticipate income: Do you expect any significant income events in the next 2-3 years (business sale, stock vesting, bonus, inheritance)? These are prime bunching opportunities.
• Consult a tax strategist: An experienced tax advisory professional can model your specific situation, calculate exact tax savings, and implement your bunching charitable deductions plan.
• Set up a DAF: Most major brokerages and community foundations offer Donor-Advised Fund services. Opening an account takes just days and positions you to implement bunching immediately.

Frequently Asked Questions

Can I change my mind about charitable distributions from a DAF after contributing?

No. Once you contribute to a DAF, it’s an irrevocable charitable contribution. However, you retain advisory privileges. You can recommend which charities receive distributions and change recommendations as your interests evolve. The sponsoring organization can refuse requests (though this rarely happens), but you cannot retrieve the funds for personal use.

What happens if I contribute more than my AGI limit for charitable deductions?

Excess deductions carry forward for up to five years. However, they may expire unused if your income doesn’t increase. Most tax planners structure bunching charitable deductions to stay within the current year’s limit (60% for cash, 30% for appreciated assets) to avoid complications and ensure full deduction utilization.

Is bunching charitable deductions ethical, or could it trigger an IRS audit?

Bunching charitable deductions is a completely legitimate, widely-accepted tax planning strategy used by millions of donors. It’s not an aggressive position. However, like any charitable deduction, maintain documentation: charitable receipts, DAF contribution confirmations, and valuation reports for appreciated assets. This documentation protects you in an audit and demonstrates good faith compliance.

Can I bunch charitable deductions if I take the standard deduction some years?

Yes. That’s the entire point. Bunching means you itemize in some years (claiming deductions including charitable contributions) and take the standard deduction in other years. You cannot claim both the standard deduction and itemized deductions in the same year, but alternating between them across years is perfectly permissible and is the core strategy of bunching.

What’s the minimum contribution to open a Donor-Advised Fund?

Most DAF sponsors require minimum initial contributions between $500 and $5,000. Some community foundations have higher minimums (up to $25,000). There’s no IRS minimum. Many high-net-worth donors open DAFs specifically for bunching charitable deductions and contribute $50,000+ in their first year, so ask sponsors about their account minimums when setting up your DAF.

How long can a DAF hold funds before distributions must occur?

There’s no IRS mandate for how quickly a DAF must distribute funds. You can hold funds indefinitely while making recommendations for distributions. However, some DAF sponsors encourage annual distributions, and a few impose payout minimums (typically 5% per year). Review your specific DAF sponsor’s policies when establishing the account.

Can I combine bunching with other deductions like SALT to maximize benefits?

Absolutely. If you have significant state and local taxes (SALT), mortgage interest, medical expenses, or other itemizable deductions, combine those with bunched charitable deductions. For example, if your SALT is $10,000 and other deductions are $15,000, you need only $8,750 in charitable bunching ($33,750 standard – $25,000) to exceed the itemization threshold. This coordination maximizes your overall deduction strategy.

What if my income fluctuates significantly year to year—can bunching still work?

Yes. Bunching works best with income fluctuation. In high-income years, contribute aggressively to your DAF. In lower-income years, take the standard deduction. This approach maximizes deduction value by matching contributions to your highest-income, highest-marginal-tax-rate years, where the deduction generates the most tax savings.
