Nonprofit Tax Compliance

Introduction

Nonprofits face unique tax challenges, from maintaining 501(c)(3) status to navigating complex reporting rules. A single error can trigger audits or penalties—or worse, revocation of tax-exempt status. This guide highlights common pitfalls and proven strategies to stay compliant.

Top Nonprofit Compliance Mistakes

1. LATE OR INCOMPLETE FORM 990 FILINGS
   Risk: Automatic $20/daypenalty(upto$12,000) for late Form 990 submissions.
   Solution:

   • Know Your Form:

     • Form 990-N: For orgs with <$50k revenue (e-file only).

     • Form 990-EZ: $50k–$200k revenue.

     • Form 990: >$200k revenue.

   • Deadlines: 5 months and 15 days after fiscal year-end (e.g., May 15 for calendar-year filers).

2. UNRELATED BUSINESS INCOME (UBI) OVERSIGHTS
   Risk: Owing taxes on UBI (e.g., advertising revenue, rental income) and penalties for non-reporting.
   Solution:

   • File Form 990-T if UBI exceeds $1,000.

   • Track expenses to offset UBI (e.g., staff costs for managing rentals).

3. IMPROPER LOBBYING ACTIVITIES
   Risk: Losing 501(c)(3) status if lobbying exceeds “insubstantial” limits.
   Solution:

   • File Form 5768 to elect 501(h) safe harbor (lobbying capped at 20% of expenses).

   • Avoid endorsing political candidates.

4. MISCLASSIFYING WORKERS AS CONTRACTORS
   Risk: IRS penalties for unpaid payroll taxes.
   Solution:

   • Use the IRS 20-Factor Test to determine worker status.

   • File Form SS-8 for uncertain cases.

5. FAILING TO MAINTAIN PUBLIC SUPPORT
   Risk: Reclassification as a private foundation (stricter rules, excise taxes).
   Solution:

   • Ensure >33% of donations come from the public (not insiders).

   • File Schedule A with Form 990 to report public support.

Case Study: How a Nonprofit Avoided Penalties
Background: A community arts nonprofit missed its Form 990 deadline, incurring $2,500 in penalties.
Solution:

• Filed Form 990-EZ with a Reasonable Cause Statement (detailing staff turnover issues).

• Implemented a compliance calendar with IRS e-file reminders.
  Outcome: Penalties abated, and tax-exempt status preserved.

FAQs
Q: Do nonprofits need to issue donor receipts?
A: Yes—for donations over $250, provide written acknowledgments (name, amount, no goods/services received).

Q: Are board members personally liable for errors?
A: Generally no, unless gross negligence or fraud is proven.

Q: Can nonprofits earn revenue?
A: Yes, but UBI over $1,000 is taxable.
