The Defined Benefit Plan Tax Credit
Most Business Owners Never Claim

Here is a number your CPA may have never mentioned: small business owners who set up a new Defined Benefit Plan can collect up to $5,000 per year — in dollar-for-dollar IRS tax credits — for three straight years. That is $15,000 back in your pocket, not as a deduction but as a direct reduction in what you owe the government. SECURE 2.0 made it happen. Almost nobody is claiming it.

If you have been considering setting up a Defined Benefit Plan or Cash Balance Plan to cut your tax bill, this changes the math significantly. You already knew about the massive annual deduction — $100,000 to $290,000 per year depending on your age. But on top of that deduction, the federal government will now hand you back up to $15,000 in credits just for getting the plan off the ground. Think of it as the IRS paying part of your setup costs while you shelter six figures of income from taxation at the same time.

This guide breaks down every credit available, who qualifies, exactly how much you can collect, and the one common mistake that disqualifies business owners before they ever file Form 8881.

What SECURE 2.0 Actually Changed

Congress passed the SECURE 2.0 Act in December 2022, and its provisions have been rolling out in waves through 2025 and 2026. One of the most overlooked provisions — Section 102 — doubled the retirement plan startup tax credit for small employers and extended it to cover Defined Benefit Plans explicitly.

Before SECURE 2.0, the startup credit was 50% of qualified costs, capped at $5,000 per year. That was useful but not transformational. After SECURE 2.0, businesses with 50 or fewer employees get 100% of qualified startup costs back as a tax credit — not a deduction, a credit — for each of the first three years the plan is active. The annual cap stays at $5,000, but when you are getting the full amount back dollar-for-dollar, that cap hits very differently than it did before.

The credit applies to any IRS-eligible retirement plan, which includes 401(k) plans, profit-sharing plans, SEP IRAs, SIMPLE IRAs, and — critically — Defined Benefit Plans and Cash Balance Plans. Most of the content you will find online about this credit focuses on 401(k)s. The DB plan angle is almost entirely uncovered, which means business owners with the most to gain from the credit are the least likely to know about it.

Three Credits You Can Stack Simultaneously

The SECURE 2.0 startup credit is actually just one of three separate tax benefits that can run concurrently when you establish a new pension plan. Here is how all three work together.

Stack all three and the math becomes hard to ignore. A physician in her mid-50s sets up a Defined Benefit Plan, adds auto-enrollment, and contributes $200,000 to the plan in year one. She collects $5,000 in startup credits, $500 in auto-enrollment credits, and deducts the full $200,000 contribution — cutting her income tax bill by roughly $74,000 at the 37% rate. Her total first-year tax benefit: approximately $79,500. Her total plan setup cost: roughly $3,000 to $5,000 in actuarial and administration fees, most of which is reimbursed by the startup credit.

Who Qualifies: The Eligibility Rules, Clearly Explained

The IRS sets specific eligibility requirements for the startup cost credit. They are not complicated, but one rule in particular catches business owners off guard. Go through this list carefully before assuming you qualify.

• ✓
  100 or fewer employees. You had 100 or fewer employees who received at least $5,000 in compensation from your business in the preceding year. This includes all full-time and part-time employees, not just plan participants.
• ✓
  At least one non-highly compensated employee. Your plan must cover at least one employee who is not a highly compensated employee (HCE). For 2026, an HCE is generally someone who owned more than 5% of the business or earned more than $160,000 in the prior year. Solo business owners with no employees do not qualify for this credit — it requires at least one eligible NHCE participant.
• ✓
  No substantially similar plan in the prior three years. In the three tax years before the first year you claim the credit, your employees were not covered by substantially the same plan with you or a predecessor business. This is the new-plan requirement — you cannot restart a terminated plan to collect the credit.
• ✗
  The employer contribution credit does NOT apply to Defined Benefit Plans. The second SECURE 2.0 credit — which reimburses a percentage of employer contributions up to $1,000 per employee — applies only to defined contribution plans like 401(k)s and SEP IRAs. Defined Benefit Plan contributions are excluded from this particular credit. However, DB contributions are fully tax-deductible separately, which is a far larger benefit at high income levels.
• ✓
  The startup cost credit DOES apply to DB plans. Unlike the contribution credit, the three-year startup cost credit explicitly covers Defined Benefit Plans as an eligible plan type. Actuarial fees, plan document costs, and annual administration fees for a DB plan all count as qualified startup costs.

How Much Can You Actually Collect? The Credit Math by Employee Count

The startup cost credit is not a flat $5,000 for everyone. The actual cap is calculated as the greater of $500 or $250 multiplied by the number of eligible non-highly compensated employees, up to $5,000 per year. Here is what that looks like across different business sizes.

The practical takeaway: if your small business has between 8 and 50 non-highly compensated employees, you will likely hit or approach the $5,000 annual cap. A medical practice, law firm, or consulting firm with a handful of staff can realistically collect the full $15,000 over three years while also deducting $200,000 to $290,000 in annual DB plan contributions.

What Counts as a Qualified Startup Cost for a Defined Benefit Plan?

The credit covers "ordinary and necessary" costs to establish and administer the plan, and to educate employees about it. For a Defined Benefit Plan, these costs are more substantial than for a simple 401(k) — which actually works in your favor, since the credit reimburses them dollar-for-dollar.

The Credit vs. The Deduction: Why You Can Claim Both

A common misconception is that the startup credit and the contribution deduction are mutually exclusive. They are not — they cover entirely different expenses and can be claimed simultaneously. Here is the clean breakdown.

The startup cost credit applies to plan administration and setup expenses — actuarial fees, document costs, Form 5500 preparation, and employee education. These are the costs of running the plan itself. Note that you cannot both deduct these same expenses and claim the credit for them — you pick one treatment for the administration costs.

The contribution deduction applies to the actual dollars you put into the Defined Benefit Plan on behalf of participants. These are your plan contributions — $100,000 to $290,000 per year depending on your age and income — and they are fully deductible from your business income regardless of whether you claim the startup credit. The deduction and the credit are entirely separate.

In practice: claim the startup credit for administration costs, then deduct your contributions separately. You get both benefits simultaneously. This is exactly what your pension consultant and CPA should be coordinating.

How to Claim It: IRS Form 8881, Step by Step

1. Confirm you meet all eligibility requirements

   Verify your employee count (100 or fewer), confirm you have at least one non-highly compensated employee participating in the plan, and confirm you have not maintained a substantially similar plan in the prior three tax years. If you are a solo owner with no employees, you do not qualify for this credit — but you still get the contribution deduction.

2. Document all qualified startup costs with receipts

   Collect invoices for actuarial fees, plan document preparation, Form 5500 filing costs, recordkeeping fees, and any employee education expenses. The IRS requires that these be paid by the employer — not the plan — and that they represent ordinary and necessary business expenses for establishing and administering the plan.

3. Complete IRS Form 8881, Part I

   Form 8881 is the "Credit for Small Employer Pension Plan Startup Costs, Auto-Enrollment, and Military Spouse Participation." Use Part I to calculate your startup cost credit. Multiply eligible costs by 100% (if you have 50 or fewer employees) or 50% (51 to 100 employees), subject to the annual cap. Your CPA or pension consultant handles this calculation.

4. Add the auto-enrollment credit if applicable

   If your Defined Benefit Plan includes an automatic enrollment feature, complete Part II of Form 8881 to claim the additional $500 per year credit. This is available for each of the first three years the auto-enrollment provision is in effect, and it stacks with the startup credit.

5. Transfer the credit to Form 3800 (General Business Credit)

   The pension startup credit flows through to IRS Form 3800, the General Business Credit form, which then carries over to your annual business return. For pass-through entities like S-Corps and partnerships, the credit flows through to Schedule K-1 and onto your personal Form 1040. Unused credits in a given year may generally be carried back one year or forward up to 20 years.

6. Deduct your plan contributions separately

   On your business return — Form 1120-S for S-Corps, Schedule C for sole proprietors, or Form 1065 for partnerships — deduct your Defined Benefit Plan contributions as a separate business expense. This deduction is completely independent of the startup credit and reduces your taxable income dollar-for-dollar. Your enrolled actuary certifies the contribution amount and your CPA applies the deduction.

Real-World Example: A Small Medical Practice

Here is how the numbers actually stack up for a physician who owns a small medical practice with eight employees — six of whom are non-highly compensated.

Setup: Dr. Patel is 54 years old, earns $380,000 in W-2 income from her S-Corp, has six NHCEs on staff, and establishes a new Defined Benefit Plan in late 2026 alongside her existing Safe Harbor 401(k).

Year one tax benefits:

Startup cost credit: Six NHCEs × $250 = $1,500. Her actual plan setup and administration costs are $4,200. She claims 100% of the lesser amount — $1,500 — as a dollar-for-dollar credit against her federal taxes. Had she 20 NHCEs, she would hit the full $5,000 cap.

Auto-enrollment credit: She adds automatic enrollment to the plan. That is an additional $500 credit in year one, year two, and year three.

Contribution deduction: The actuary calculates her annual Defined Benefit Plan contribution at $205,000, based on her age and compensation. She contributes $205,000 to the plan and deducts the full amount from her S-Corp income. At the 37% federal rate, that is a $75,850 reduction in her federal income tax for the year.

Year one total benefit: $77,850 in tax savings plus $2,000 in credits. Her out-of-pocket plan administration costs after the credit: approximately $2,700.
