The 2017 Tax Cuts and Jobs Act (TCJA) fundamentally reshaped charitable giving in America, concentrating philanthropic power among the ultra-wealthy while diminishing incentives for everyday donors. As the sunset of key TCJA provisions approaches in 2026, astute investors face a critical juncture, with new tax rules poised to further influence how and when they contribute. Understanding these shifts and proactively planning giving strategies is essential for maximizing both social impact and financial efficiency.
The landscape of American philanthropy is undergoing a profound transformation, driven significantly by policy changes introduced under the first Trump administration. The Tax Cuts and Jobs Act (TCJA) of 2017, while heralded for its broader economic impact, quietly instigated a two-step alteration in charitable giving: it reduced tax incentives for middle-class donors and simultaneously empowered ultra-wealthy philanthropists. This shift carries substantial implications for democracy, equality, and the sustainability of nonprofit organizations, creating a new environment that demands strategic consideration from investors.
The TCJA’s Initial Impact: A Shift in Giving Dynamics
Prior to the TCJA, roughly 30% of taxpayers itemized their deductions, allowing them to claim a tax break for charitable contributions. The 2017 act nearly doubled the standard deduction, leading to a dramatic reduction in the number of households itemizing their taxes. By 2018, only about 10% of taxpayers were itemizing, according to IRS data. This change effectively eliminated the charitable deduction for millions of middle-class Americans.
Economists Mark Ottoni-Wilhelm and Xiao Han, in a study analyzing the post-TCJA landscape, found that Americans who stopped itemizing gave nearly $1,000 less to charity in 2018 than they otherwise would have. This contributed to an estimated $20 billion reduction in charitable giving from individual donors in the year following the bill’s enactment, representing about 5% of all charitable giving, as reported by the Giving USA Foundation in partnership with the Indiana University Lilly Family School of Philanthropy. While total charitable giving eventually rose in nominal terms by 2023, giving from individual donors still saw a decline of $2 billion from 2017 levels, underscoring the sustained impact on broad-based giving.
Conversely, the TCJA provided tailored benefits to wealthy donors through mechanisms like increased estate tax exemptions and corporate tax cuts. This facilitated a significant concentration of philanthropic power. Before the TCJA, the top 1% of earners controlled 40% of charitable donation value; post-TCJA, this figure jumped to 56%, as highlighted in a research report from the University of Washington School of Law. This emergence of a “philanthropist class” means philanthropic priorities increasingly reflect the interests of the ultra-wealthy, potentially overlooking diverse community needs.
The Approaching 2026 Sunset: New Rules and Strategic Considerations
Many provisions of the TCJA are set to expire in 2026, presenting Congress with an opportunity to revisit tax incentives for charitable giving. This expiration will introduce new rules that financial experts, like Jane Ditelberg of The Northern Trust Institute, advise investors to carefully consider for their year-end giving strategies.
Changes for Itemizers
For taxpayers who itemize their deductions, two significant changes will take effect in 2026:
- 0.5% Adjusted Gross Income (AGI) Floor: Only charitable contributions exceeding 0.5% of a taxpayer’s AGI will be deductible. For example, an individual with a $200,000 AGI would find their first $1,000 in donations non-deductible.
- 35% Cap on Deduction Value: For those in the top 37% tax bracket, the tax benefit from all itemized deductions will be capped at a 35% tax rate. This means a top earner donating $10,000 will see a $3,500 tax reduction, down from the $3,700 benefit under current rates.
Given these impending changes, financial advisors suggest that itemizers accelerate their giving by making larger donations in 2025 to bypass the new floor and capitalize on the current 37% deduction rate. High-net-worth individuals might also consider “bunching” two or more years of donations into 2025 to maximize their deductions before the new cap takes effect.
Opportunities for Non-Itemizers
In a notable shift, non-itemizers—who comprise about 90% of filers—will regain a charitable contribution deduction starting in 2026:
- Above-the-Line Deduction: Non-itemizers will be able to claim a deduction for cash donations of up to $1,000 for single filers and $2,000 for couples filing jointly. This deduction is “above-the-line,” meaning it reduces taxable income regardless of whether a taxpayer itemizes.
This new deduction mirrors a temporary provision under the CARES Act during the COVID-19 pandemic (2020 and 2021). That earlier provision, capped at $300 for single filers and $600 for joint filers, spurred nearly $11 billion in additional giving in 2020 and $18 billion in 2021, primarily from small donors. For non-itemizers, the strategic advice is reversed: defer cash donations until 2026 to take advantage of this new tax break, as contributions in 2025 will not offer a similar deduction.
Strategic Tools for Maximizing Philanthropic Impact
Beyond simply timing donations, investors have several tools to optimize their charitable giving:
- Donor-Advised Funds (DAFs): A DAF allows givers to contribute assets, receive an immediate tax deduction, and then recommend grants from the fund to charities over time. The money within the DAF can also be invested and grow tax-free. As Claudia Gonzalez, Principal in Kaufman Rossin’s Tax Services Advisory Group, notes, DAFs are an excellent option for those who want to front-load deductions but disburse funds gradually.
- Private Foundations: For individuals seeking greater control over their philanthropic endeavors and with substantial assets, establishing a private foundation offers a dedicated vehicle. While more complex and costly to establish and manage, private foundations provide ultimate control over investment and grant-making decisions.
- Donating Property and Goods: It is important to remember that charitable contributions are not limited to cash. Donations of appreciated assets like stocks, real estate, or even tangible personal property can offer significant tax advantages, allowing donors to avoid capital gains tax while still receiving a deduction.
The Enduring Value of Charitable Giving in Civil Society
The charitable deduction, a cornerstone of the U.S. tax code since 1917, plays a vital role in fostering civil society. It encourages support for a vast array of organizations—from local park conservancies and school scholarship programs to medical research and religious congregations—that often provide services the government cannot or should not. While tax incentives cost the government revenue, the social value generated by these contributions is immense. The U.S. has historically been recognized as one of the world’s most charitably generous nations, a testament to the effectiveness of these incentives.
As the debate heats up around the expiration of the TCJA’s provisions, policymakers will weigh the fiscal implications against the profound social benefits of encouraging widespread charitable giving. For investors, understanding these shifts is not merely about tax optimization, but about strategically deploying capital to support causes that align with their values and contribute to the fabric of communities.
