Nonprofits rethink donor communication in a new tax environment

Charitable giving has long responded to tax policy. When the after-tax cost of giving decreases, donations tend to rise—particularly among high-income households. When incentives weaken, giving often softens. With the latest federal tax law changes now in effect for 2026, that relationship is shifting once again. 

Some of the most notable changes are to the charitable contribution deduction rules that could affect nonprofits and their donors. These rule changes could disrupt established fundraising models.

For nonprofit leaders, the implication is clear: Maintaining traditional communication strategies may not be enough to sustain donor engagement. Growth in the new tax environment will require sharper messaging, smarter segmentation and stronger technology infrastructure.

A necessary shift in communication

Nonprofits must evolve from tax-centric messaging to impact-centered engagement. For decades, year-end appeals have emphasized tax deductibility: “Make your tax-deductible gift before Dec. 31” has been a common call to action. Today, this traditional communication to donors will need to shift due to tax law changes for 2026 and beyond.

These changes affect each segment of donors differently. For example, donors who itemize their deductions have traditionally contributed much larger amounts than those who do not. Following the 2017 Tax Cuts and Jobs Act, the number of itemizers decreased, and as a result, charitable giving declined in 2018 and 2019. 

That precedent reinforces an important principle: Donor behavior is sensitive to shifts in the perceived value or benefit of giving. In this case the new tax law provisions reintroduce a deduction for non-itemizers, creating an opportunity for nonprofits. While individual gifts in this segment may be smaller, the scale of potential participation is substantial. Organizations that broaden their donor base strategically could offset declines at the top.

The importance of DAF outreach

Donor advised funds (DAFs) are among the fastest-growing methods of charitable giving, making them a key part of philanthropy. Recently, the DAF Research Collaborative published their annual DAF report, revealing that total assets in DAFs rose by over 27% to reach almost $327 billion in 2024. Contributions to DAFs went up by 37% to almost $90 billion, while grantmaking from DAFs increased 19%, totaling almost $65 billion in 2024.

The findings highlight the importance of enhancing DAF outreach. Nonprofits should make DAF giving straightforward and visible while offering continued support for this vehicle. It is essential for nonprofits to track gifts from DAFs and maintain strong connections with community foundation sponsors. Proactive engagement helps ensure consistent grant flows, even when contribution timelines shift.

However, while DAF contributions remain deductible for itemizers (subject to new taxable income floors), the new above-the-line deduction for non-itemizers does not apply to DAF contributions. This distinction may influence contribution timing and structure in 2026.

Shifting corporate relationships

Corporate giving also faces recalibration. With the introduction of a 1% taxable income floor for deductibility, companies may reconsider their charitable budgets and focus on forming more strategic, long-term partnerships that support environmental, social and governance (ESG) goals and business objectives.

Nonprofits can benefit by positioning themselves as strategic community partners instead of just recipients of donations. Establishing multiyear commitments, aligning impact reporting with ESG frameworks and engaging in skills-based initiatives can enhance corporate-nonprofit relationships, even amid changes to deduction policies.

Corporate donations are unlikely to disappear. However, they may be redistributed across vehicles, time frames and donor segments.

New approaches to communication

To sustain and grow contributions, organizations should consider these communication strategies:
