Who Can Claim These Credits? Eligibility for Small Employers?
To qualify as an eligible small employer, your business must meet these IRS criteria:
- Employee count: No more than 100 employees who received at least $5,000 in compensation in the tax year before your first credit year.
- Prior plans restriction: You didn’t maintain a similar qualified plan for substantially the same employees in the 3 tax years before the first credit year.
- Controlled groups: Treat businesses under common control, affiliated service groups, or predecessor employers as one entity for eligibility.
Qualifying plans include qualified employer plans under IRC Section 4972(d), like 401(k)s, profit-sharing plans, or SEP IRAs, with at least one non-highly compensated employee participating.
Note: Partnerships and S corporations pass credits through to owners, who report them on Form 3800 without filing Form 8881 themselves.
The Four Credits on Form 8881: What You Can Claim?
Form 8881 has three parts for distinct credits under IRC Sections 45E, 45T, and 45AA. Here’s a breakdown:
1. Small Employer Pension Plan Startup Costs Credit (Part I, Section 1)
This credit covers ordinary and necessary expenses to set up or administer a plan, plus employee retirement education.
- Credit percentage:
- 100% for employers with 1–50 qualifying employees.
- 50% for those with 51–100.
- Annual limit: Greater of $500 or the lesser of ($250 × eligible non-highly compensated employees) or $5,000.
- Available for: First credit year (when plan effective) + next 2 years.
- Qualified costs: Plan setup/administration and employee education (not ongoing contributions).
Example: A 30-employee business with $6,000 in startup costs claims 100% ($6,000), capped at $5,000 (greater of $500 or $250 × 20 eligible employees).
2. Small Employer Contributions Credit (Part I, Section 2)
A new SECURE 2.0 addition, this credits employer contributions (excluding elective deferrals) to an eligible plan.
- Per-employee cap: Up to $1,000 initially, phased down over 5 years.
- Applicable percentages (for first 5 years post-plan effective):
Year Percentage 1–2 100% 3 75% 4 50% 5 25% - Exclusions: Contributions for employees earning over $105,000 (inflation-adjusted wages).
- Reduction: 2% per employee over 50 in the prior year.
Reduce your deductible contributions by the credit amount.
3. Small Employer Auto-Enrollment Credit (Part II)
For adding an eligible automatic contribution arrangement (under IRC Section 414(w)(3)) to a qualified plan.
- Credit amount: $500 per year for the first year included + next 2 years (if maintained).
- Eligibility: Same as general small employer rules (≤100 employees with $5,000+ pay).
This pairs well with mandatory auto-enrollment rules starting in 2025 for new plans.
4. Small Employer Military Spouse Participation Credit (Part III)
Encourages plans benefiting military spouses.
- Credit: $200 per qualifying military spouse participant + up to $300 in employer contributions (excluding deferrals), for up to 3 years per spouse.
- Plan requirements: Military spouses eligible within 2 months of hire, get same contributions as others after 2 years, and have nonforfeitable benefits.
- Military spouse definition: Non-highly compensated employee married to active-duty uniformed services member (relying on self-certification).
