When the One Big Beautiful Bill Act (OBBBA) was signed into law in 2025, most of the headlines centered on income brackets, inflation adjustments, and government spending. But for generous families, entrepreneurs, and ministries, the more pressing question is this: how does this new legislation affect charitable giving?
The short answer is clear. Beginning in 2025, new rules will limit the tax efficiency of charitable gifts. For those who give regularly or plan to make a major donation, accelerating contributions into 2025 could be one of the smartest financial and philanthropic moves of the decade.
Why Giving in 2025 Matters More
Starting in 2025, two significant changes will affect how charitable deductions are calculated.
The Deduction Floor
Charitable gifts will need to exceed 0.5 percent of adjusted gross income (AGI) before they become deductible. For example, if your AGI is $500,000, the first $2,500 of your charitable gifts will no longer qualify for a deduction.
The Deduction Ceiling
For those in higher tax brackets, the maximum deduction rate for charitable contributions will drop from 37 percent to 35 percent. While that may seem like a small adjustment, it slightly reduces the overall tax savings available to top-tier givers.
Together, these changes create a strong incentive to front-load giving in 2025, when deductions are still fully optimized.
Estate and Gift Exclusion: More Room for Strategic Giving
The OBBBA also permanently increased the federal estate tax exclusion amount to $15 million per individual and $30 million for married couples, effective in 2025.
For most families, this higher threshold provides peace of mind and simplifies estate planning. For larger estates, however, it presents an opportunity to give more intentionally. By incorporating charitable gifts into estate plans, families can direct resources to causes they care about while reducing potential tax exposure.
Many philanthropically minded individuals are using this flexibility to establish foundations, endowments, and ministry gifts that reflect their values for generations to come.
Other Key Tax Changes for Givers in 2025
Standard Deduction Increase
The standard deduction will rise to $15,750 for individuals and $31,500 for married couples. With this change, fewer taxpayers will itemize deductions, meaning many may no longer benefit from smaller annual charitable gifts.
The “Bunching” Strategy
To maintain tax efficiency, donors may consider “bunching” two or three years of planned giving into a single year. This approach allows donors to exceed the standard deduction threshold and claim the full benefit of itemized deductions.
Above-the-Line Deduction
Non-itemizers will still be able to deduct up to $1,000 (or $2,000 for couples) in cash gifts to qualifying charities. However, this provision does not apply to contributions made through donor-advised funds.
What It Means for You
If you are deciding whether to make significant charitable contributions this year or next, 2025 is the clear winner. By giving now, you can maximize both your philanthropic impact and your tax advantages before the new restrictions take effect.
