Most credit union leaders sleep well at night knowing they’re federally tax-exempt. But here’s the wake-up call: tax-exempt doesn’t mean tax invisible.
The IRS may not be after your core member service income, but there are dozens of ways a credit union can end up under federal tax scrutiny — and the penalties can be severe.
Fun Fact #1: The IRS Has a Credit Union Playbook
The IRS maintains an actual examination guide for credit unions that outlines what agents should look for, including:
- Unrelated Business Income Tax (UBIT) exposure
- Executive compensation reporting
- Payroll tax compliance
- Reporting of certain investment and partnership income
The Most Common IRS Triggers for Credit Unions
- Unreported UBIT — Non-member income from insurance sales, investment products, ATM fees, or marketing partnerships.
- Payroll Tax Errors — Misclassifying employees, missing deposits, or incorrect 941 filings.
- Information Return Failures — Late or missing 1099s for contractors and vendors.
- Excessive or Improper Executive Perks — Housing allowances, vehicles, or travel without proper documentation.
- Investment Income — From partnerships or unrelated ventures not reported correctly.
Example from the Field
A credit union partnered with a third-party insurance provider, earning $180,000 over three years. They didn’t realize this income was partially taxable under UBIT rules. When the IRS audited, the result was $52,000 in back taxes, $19,000 in penalties and interest, and a six-month distraction for the CFO and accounting team — all of which could have been avoided with a CPA-led revenue review.
Fun Fact #2: UBIT Isn’t Always Obvious
Even income from investments in certain CUSOs (Credit Union Service Organizations) can be taxable, depending on the activity and ownership structure.
CPA Insight: The IRS Cares About Documentation
In most IRS disputes, the issue isn’t that a credit union can’t justify the expense or income treatment — it’s that they can’t prove it. We advise credit unions to:
- Maintain detailed revenue source breakdowns
- Track member vs. non-member transactions
- Keep written policies for executive benefits and perks
- Reconcile payroll tax filings with internal records quarterly
Five Ways to Stay Off the IRS Radar
- Review All Non-Member Income Annually — Especially from partnerships and investments.
- Audit Payroll Tax Compliance — Correct errors before the IRS finds them.
- Tighten Vendor and Contractor Files — W-9s, 1099s, and contracts on record.
- Document Executive Compensation — Including fringe benefits.
- Stay Current on Tax Law Changes — IRS interpretations evolve.
Fun Fact #3: The IRS Doesn’t Care That You’re a Credit Union
Your member-owned status may win hearts in the community — but to the IRS, you’re just another taxpayer when it comes to UBIT and compliance.
The Strategic View
The IRS isn’t looking for a fight — but it is looking for revenue. The most prepared credit unions identify tax risks before the IRS does, maintain airtight documentation, and use CPA expertise to structure activities in tax-efficient, compliant ways.
Our Role in IRS Defense
We help credit unions review all potential UBIT exposure, build audit-ready tax documentation, and defend positions with solid financial and legal grounding.
