Here's a number most small business owners have never heard: $16,500. That's the maximum a small employer can claim in federal tax credits in a single year just for starting a retirement plan and helping employees save into it. Stack that over five years and a business with a handful of workers can offset tens of thousands of dollars in what most owners assume is a pure cost center.
Retirement benefits have always felt like something only larger companies could afford — a line item competing with payroll, rent, and inventory. SECURE 2.0, the retirement-reform law that built on the original SECURE Act, was written specifically to close that gap. It turns three separate startup costs — plan administration, employee contributions, and auto-enrollment — into dollar-for-dollar tax credits, not deductions. And in 2026, with more states rolling out mandatory retirement-savings laws, the credit isn't just free money on the table; for a growing number of businesses, it's the cheapest way to comply with a requirement they're going to face either way.
Why This Matters More in 2026 Than It Did a Few Years Ago
As of mid-2026, 22 states and 3 cities have enacted "auto-IRA" style mandates that require employers above a certain size to offer retirement savings — either their own plan or the state-run alternative. California, Oregon, and Hawaii set the bar as low as one full-time employee; Colorado, Connecticut, Delaware, Maine, Minnesota, and Virginia use a five-employee threshold. If your business operates in one of these states and doesn't already offer a plan, you likely have to do something about it soon regardless of whether you want the tax credit.
That changes the calculus. A business facing a state mandate isn't choosing between "offer a plan" and "don't." It's choosing between the state's auto-IRA — which has lower contribution limits, no employer match, and less design flexibility — and a private 401(k), SEP IRA, or SIMPLE IRA that the federal government will help pay to set up. For many owners, running the numbers for the first time is what makes clear that the "employee benefit competing with the budget" framing was backwards all along.
The Three Credits, Broken Down
SECURE 2.0 didn't create one credit — it created three, and they can be claimed together in the same tax year.
1. The Startup Cost Credit — up to $5,000 per year for three years
This covers the cost of setting up and administering a new retirement plan: paying a provider to establish the plan, ongoing administrative fees, and the cost of educating employees about their options.
- Employers with 50 or fewer employees: 100% of qualified startup costs are creditable, up to the greater of $500 or the lesser of ($250 × number of non-highly-compensated employees) or $5,000, per year.
- Employers with 51–100 employees: the credit phases down, capped at 50% of costs up to $5,000 per year.
Run that for three consecutive years and a small employer can claim up to $15,000 total — the number that gives the credit its reputation, even though the exact figure depends on headcount.
2. The Employer Contribution Credit — up to $1,000 per employee
This is the newer, and often larger, piece. If you actually contribute to your employees' accounts — a match, a profit-sharing contribution, whatever your plan design calls for — you can claim a credit worth up to $1,000 per eligible employee earning $100,000 or less in the prior year.
The catch is that it phases down over five years:
| Year | Credit percentage |
|---|---|
| Year 1 | 100% |
| Year 2 | 100% |
| Year 3 | 75% |
| Year 4 | 50% |
| Year 5 | 25% |
For businesses with 51–100 employees, the credit additionally phases out by 2% for each employee above 50 — so a 75-employee business sees a materially smaller credit than a 45-employee one, independent of the year-based phasedown.
3. The Auto-Enrollment Credit — $500 per year for three years
Adding an automatic enrollment feature — where eligible employees are enrolled by default and have to actively opt out, rather than opt in — earns a flat $500 credit annually for three years. This applies whether you're setting up a brand-new plan with auto-enrollment built in or adding the feature to a plan you already have. It's a small credit on its own, but it stacks cleanly on top of the other two, and auto-enrollment reliably increases plan participation, which is worth something even without the tax benefit.
Who Actually Qualifies
The eligibility bar is intentionally low, and it's worth checking even if you assume you're too small:
- No more than 100 employees who received at least $5,000 in compensation in the prior year. (Employees paid less than $5,000 don't count toward this cap — a detail that matters for businesses with a lot of part-time or seasonal staff.)
- You haven't sponsored a plan covering substantially the same employees in the prior three tax years. This credit is for starting something new, not for a plan you've already had running.
- At least one non-highly-compensated employee must be eligible to participate. A one-owner business with no staff generally can't claim the startup and contribution credits — though a solo 401(k) can still make sense for other tax reasons.
One practical wrinkle: the credits are nonrefundable. They reduce your tax liability dollar-for-dollar but can't take it below zero, and unlike some credits, unused amounts generally don't carry forward under this provision. If your business isn't consistently profitable enough to owe meaningful federal tax, model the actual benefit before assuming you'll capture the full $15,000-plus.
How to Claim It: Form 8881
All three credits are claimed on IRS Form 8881, Credit for Small Employer Pension Plan Startup Costs, filed with your business return. The form separates the startup cost credit, the auto-enrollment credit, and the employer contribution credit into distinct sections, and the total flows into the general business credit calculation on Form 3800.
A few things worth confirming with your tax preparer before you file:
- Whether your plan provider itemizes startup costs in a way that maps cleanly to the "qualified startup costs" definition (administration and employee education, not investment management fees).
- Whether you're claiming the credit in the year costs were paid or incurred — the form allows the credit to start the year before the plan is established, which surprises some owners.
- Whether the employer contribution credit interacts with your Section 404 deduction for the same contributions (it can — you generally can't double-dip on the identical dollars, but the interaction is more favorable than it sounds).
Which Plan Type Actually Makes Sense
The credit applies to any "eligible employer plan" — which in practice means a 401(k), SIMPLE IRA, or SEP IRA (SEP IRAs don't allow auto-enrollment, so they're ineligible for that third credit specifically). The right choice depends less on the tax credit and more on what you need the plan to do:
- SIMPLE IRA — lowest administrative burden, mandatory employer contribution, lower contribution limits. A reasonable starting point for a business with under 25 employees that wants something simple.
- 401(k) — the most flexible design (matching formulas, profit-sharing, loans, Roth options), the highest contribution limits, and the only structure that supports true auto-enrollment with the fullest range of credit eligibility. Higher setup and administrative cost, which is exactly what the startup credit is designed to offset.
- SEP IRA — employer-funded only, extremely simple, but contributions must be a uniform percentage across all eligible employees, which can get expensive fast once you have several employees on the payroll.
If your state has an auto-IRA mandate, compare the total five-year cost of a 401(k) net of credits against simply defaulting into the state program. For most businesses with even a modest number of employees, the private plan comes out ahead once the credits are factored in — and it comes with plan design control the state program doesn't offer.
Setting Up Your Books Before You Set Up the Plan
Whichever plan you choose, the tax credit calculation depends on accurate compensation and headcount records — exactly the kind of detail that gets messy when payroll data lives in one system, contractor payments in another, and the actual filing in a spreadsheet nobody's updated since March. Knowing precisely how many employees earned over $5,000 last year, and what each eligible employee earned this year, is what determines your credit amount down to the dollar.
