Tax Implications for Nonprofit Organizations

Nonprofit leaders juggle a lot. Fundraising, programming, community outreach, board management, and on top of that, a long list of tax rules to keep your organization compliant. Understanding the basics helps protect your exempt status and keeps your team focused on mission work instead of scrambling during filing season. Below is an easy-to-follow overview of the most important areas to keep in mind.

Understanding Tax-Exempt Status

Earning tax-exempt status is one thing. Keeping it is another. To stay compliant under Section 501(c)(3) or another tax-exempt “(c)(#)” category, organizations must operate for a recognized charitable purpose and avoid activities that benefit private individuals or insiders. Once granted exemption, nonprofits are responsible for maintaining clear records, operating within their mission, following rules related to political activity, and completing required IRS filings annually.

Missing a deadline can lead to penalties that can be difficult to abate, and failing to file for three consecutive years results in automatic revocation of tax-exempt status. To regain tax-exempt status after automatic revocation, the organization must file Form 1023 for reinstatement.

Key Nonprofit IRS Forms & Filing Deadlines

There are different types of tax-exempt tax returns, and the type that needs to be filed depends on revenue, assets, and organizational structure. Here is a quick look at what most organizations file:

• Form 990: Gross receipts more than $200,000 and assets of $500,000 or more at year-end
• Form 990 EZ: Gross receipts between $50,000 - $200,000 and assets less than $500,000 at year-end 
• Form 990 N: The e-Postcard for organizations with gross receipts normally less than $50,000
• Form 990 PF: Required for private foundations of any size

All versions are generally due on the fifteenth day of the fifth month after the fiscal year ends. If the return is not completed by the original due date, Form 8868 must be filed, and it will grant the organization an additional 6-month extension to file the respective 990. For example, with a December 31st year-end, the original due date will be May 15th. The extended due date would be November 15th.

When Unrelated Business Taxable Income (UBTI) Applies

UBTI is an area where we can see nonprofits become subject to tax. UBTI applies when three criteria are met: when revenue comes from a (1) trade or business that is (2) regularly carried on (conducted frequently and consistently) and (3) not substantially related to the exempt mission.

For example, a nonprofit that runs a small café open daily to the public may face UBTI if the café does not meaningfully support the organization’s charitable purpose. Similarly, selling advertising space, offering paid services unrelated to the mission, or earning rental income on debt-financed property may create UBTI obligations.

If a tax-exempt organization has gross UBTI of $1,000 or more during the filing year, the organization must file Form 990-T and pay the applicable tax. For tax-exempt organizations organized as a corporation, the tax rate is 21% on the net UBTI. For exempt trusts, the tax rate is typically 37%.

Many nonprofits can avoid being surprised by UBTI tax by reviewing activities annually and documenting why each revenue stream does or does not support mission work. If a new revenue stream occurs during the year, it is best to reach out to a tax professional to determine if that revenue stream will be subject to tax when the return is filed.

Donor Acknowledgment & Contribution Reporting

This is one of the most visible compliance areas because it affects donors directly. Proper donation acknowledgment builds trust and helps supporters confidently claim their tax deductions.

For gifts of $250 or more, nonprofits must provide written acknowledgment with specific language. This should include the amount or description (for non-cash) of the gift and whether any goods or services were provided in exchange. For quid pro quo contributions over $75, organizations must disclose the value of benefits the donor received so the donor understands what portion is deductible. For example, if a donor purchased a seat at a charity dinner for $1,000, and the meal was worth $100, only $900 would be tax-deductible.

State Level Considerations

Federal rules get most of the attention, but state tax requirements can have just as much day-to-day impact. Certain states require annual filings, separate from federal filings, to maintain state-level tax-exempt status. Nebraska tends to be pretty lax compared to other states, so make sure to double-check any state-level filings if operating within a new state. Some states require nonprofits to apply for sales or use tax exemptions instead of granting them automatically. Property tax exemptions may also require applications and periodic renewals, especially if the property is used for mixed purposes.

Encouraging Giving Through Tax Incentives

While nonprofits cannot give tax advice, they can help donors understand the general tax benefits available. Many supporters are motivated by knowing that their giving can also offer financial advantages.

A few examples include:

• Charitable deductions
• Qualified charitable distributions from IRAs
• Employer matching gift programs
• State-specific credit programs

When donors understand their options, stewardship conversations tend to flow more naturally.

Why Good Record Keeping Matters

Record keeping is not just about IRS compliance. It drives organizational clarity. Strong documentation helps leaders understand program costs, analyze funding sources, and prepare accurate financial statements.

At a minimum, nonprofits should maintain:

• Donation receipts
• Grant agreements
• Payroll and HR records
• Board minutes
• Expense documentation
• Policies related to governance and financial oversight

Risks of Noncompliance

None of these rules exists in isolation. Falling behind in one area can impact others. Penalties, donor concerns, loss of exemption, and audit issues are all possible outcomes.

In our work with clients, most compliance problems stem from capacity limitations rather than intentional missteps. Clear processes, good documentation, and periodic reviews help nonprofits stay ahead of potential issues.
