Form 8881: The Small Employer Pension Startup Credit Explained
Published November 7, 2026
Form 8881 is the form an eligible small employer uses to claim credits for retirement plans. The Instructions for Form 8881 (Rev. December 2025) describe three separate parts. This post is general information. It is not advice about a specific plan.
Three parts, three credits
Part I covers two credits under section 45E. One is the startup costs credit. The other is the contributions credit. Part II covers the auto-enrollment credit under section 45T. Part III covers the military spouse credit under section 45AA.
A taxpayer other than a partnership or S corporation does not file Form 8881 if its only source of these credits is a partnership or S corporation. That taxpayer reports the credit on Form 3800 instead. The credits are part of the general business credit.
An employer can elect not to have section 45E apply for a tax year. To do that, it does not claim the credit on that year's return.
Startup costs credit (Part I, section 1)
For tax years beginning after 2022, an employer with 1 to 50 employees can claim 100% of its qualified startup costs. An employer with 51 to 100 employees gets 50%.
The credit has a limit. It is the greater of $500 or the lesser of two amounts. The first amount is $250 for each eligible employee who is not highly compensated. The second is $5,000. The instructions say this limit applies in the first credit year and the 2 tax years after it.
Qualified startup costs are expenses paid to set up or run an eligible plan. They also include retirement education for employees about the plan.
An eligible employer has no more than 100 employees. Those employees received at least $5,000 of pay from the employer in the prior tax year. The employer is not eligible if, in the 3 tax years before the first credit year, it had a qualified plan for substantially the same employees.
The employer must reduce its startup cost deduction by the credit amount.
Contributions credit (Part I, section 2)
This credit is a percentage of the employer's contributions to an eligible plan. The limit is $1,000 per employee. The credit applies in the first year the plan is effective and in the 4 years after that.
The percentage is 100% in the first and second years. It is 75% in the third year, 50% in the fourth year, and 25% in the fifth year.
Elective deferrals do not count as contributions. Contributions for an employee with more than $105,000 in wages for the year also do not count. The percentage drops by 2% for each employee over 50.
Auto-enrollment credit (Part II)
Under section 45T, the credit is $500 for the first tax year the employer includes an eligible automatic contribution arrangement. It is $500 for each of the 2 tax years after that. The employer must keep the arrangement in place.
Military spouse credit (Part III)
Under section 45AA, this credit applies to eligible plans with individual accounts. The plan must have certain features for military spouses.
A military spouse is an employee who is not highly compensated. The employee is married to a member of the uniformed services on active duty when employment starts. The instructions say an employer may rely on the employee's certification. The certification must give the spouse's name, rank, and service.
Controlled groups count as one employer
For these credits, related businesses act as one employer. That includes controlled groups of corporations, businesses under common control, and affiliated service groups. Each member figures its share of the credit. A statement explains how the share was figured.
What to keep in mind
Form 8881 depends on plan facts. These include the number of employees, the plan's effective date, the costs and contributions paid, and prior-year pay. Keep the records that support each number. The general business credit is covered in Form 3800: How Business Credits Are Combined. The plan types are covered in A 401(k) for a small business.
