As a finance expert, I often encounter questions about retirement planning for nonprofit organizations, particularly those classified under 501(c)(6). These entities—trade associations, chambers of commerce, and professional leagues—have unique retirement plan options that differ from corporate or individual plans. In this guide, I will break down everything you need to know about 501(c)(6) retirement plans, including plan types, tax advantages, compliance, and optimization strategies.

Understanding 501(c)(6) Organizations
Before diving into retirement plans, it’s crucial to define what a 501(c)(6) organization is. The IRS grants this designation to business leagues, trade associations, and professional organizations that promote common business interests without generating profits for members. Unlike 501(c)(3) charities, donations to 501(c)(6) groups are not tax-deductible.
Key Characteristics:
- Nonprofit but not charitable – Focused on member benefits rather than public welfare.
- Revenue sources – Membership dues, event fees, sponsorships.
- Tax-exempt status – Exempt from federal income tax but must pay unrelated business income tax (UBIT) on non-mission-related revenue.
Retirement Plan Options for 501(c)(6) Organizations
501(c)(6) organizations can offer several retirement plans, each with distinct features. Below, I compare the most common options:
1. 401(k) Plans
A traditional 401(k) allows employees to defer a portion of their salary into a retirement account. Employers may match contributions.
Advantages:
- Higher contribution limits – In 2024, employees can contribute up to $23,000 (plus a $7,500 catch-up for those 50+).
- Employer matching – Can boost employee retention.
- Roth option – Post-tax contributions for tax-free withdrawals.
Example Calculation:
If an employee earns $80,000 and contributes 10% ($8,000), and the employer matches 50% of the first 6% ($2,400), the total annual contribution is $10,400.
2. 403(b) Plans (Only for Certain 501(c)(6) Orgs)
Some 501(c)(6) organizations (e.g., those affiliated with educational or medical fields) may qualify for a 403(b). These resemble 401(k)s but are limited to annuities and mutual funds.
Key Differences from 401(k):
- Fewer investment options – Primarily annuities.
- No ADP/ACP testing – Reduces administrative burden.
3. Defined Benefit (Pension) Plans
A pension plan guarantees a fixed payout at retirement based on salary and tenure.
Pros:
- Predictable retirement income – Attracts long-term employees.
- High contribution limits – Employers can contribute significantly more than in 401(k)s.
Cons:
- Costly to maintain – Requires actuarial valuations.
- Funding liability – Must meet minimum funding standards.
Mathematical Illustration:
For an employee with a final average salary of $100,000 and 20 years of service, a plan offering 1.5% per year would provide:
4. SIMPLE IRA
A SIMPLE IRA is a low-cost option for small 501(c)(6) organizations (under 100 employees).
Features:
- Employee contributions – Up to $16,000 in 2024.
- Mandatory employer match – Either a 2% non-elective or 3% matching contribution.
Best for: Small associations with limited administrative resources.
5. SEP IRA
A Simplified Employee Pension (SEP) IRA allows employers to contribute directly to employees’ IRAs.
Contribution Limits:
- Up to 25% of compensation or $69,000 (2024), whichever is lower.
Example:
For an employee earning $60,000, the max employer contribution is:
Comparing Retirement Plans for 501(c)(6) Organizations
| Plan Type | Max Employee Contribution (2024) | Employer Contribution | Best For |
|---|---|---|---|
| 401(k) | $23,000 (+$7,500 catch-up) | Optional match | Larger orgs |
| 403(b) | $23,000 (+$7,500 catch-up) | Optional match | Educational/medical 501(c)(6) |
| Defined Benefit | N/A (Employer-funded) | Actuarially determined | Orgs with stable cash flow |
| SIMPLE IRA | $16,000 (+$3,500 catch-up) | Mandatory 2-3% match | Small orgs |
| SEP IRA | N/A (Employer-only) | Up to 25% of salary | Solo or small teams |
Tax Advantages and Compliance
Tax-Deferred Growth
Contributions to traditional 401(k)/403(b)/SIMPLE IRA reduce taxable income. Earnings grow tax-free until withdrawal.
Example:
If a 501(c)(6) employee in the 24% tax bracket contributes $10,000, their taxable income drops by $10,000, saving $2,400 in taxes.
Roth Option (After-Tax Contributions)
Some plans allow Roth contributions, where withdrawals in retirement are tax-free. Useful if tax rates rise.
Unrelated Business Income Tax (UBIT) Considerations
If a 501(c)(6) organization earns income from non-mission activities (e.g., selling ads), it may owe UBIT. Retirement plan contributions can reduce UBIT liability.
Compliance and Fiduciary Responsibilities
501(c)(6) organizations must follow ERISA guidelines, including:
- Nondiscrimination testing – Ensuring benefits don’t favor highly compensated employees.
- Filing Form 5500 – Required for plans with 100+ participants.
- Fiduciary duty – Acting in the best interest of plan participants.
Optimizing Your 501(c)(6) Retirement Plan
1. Auto-Enrollment
Boosts participation rates by automatically enrolling employees (with opt-out options).
2. Safe Harbor 401(k)
Avoids nondiscrimination testing by providing mandatory employer contributions.
3. Financial Wellness Programs
Educating employees on retirement planning improves engagement.
Final Thoughts
Choosing the right retirement plan for a 501(c)(6) organization depends on size, budget, and employee needs. A 401(k) suits larger groups, while a SIMPLE IRA works for smaller teams. Defined benefit plans offer stability but require strong cash flow.
