Key Takeaways

Offering an employee retirement plan can deliver significant tax savings while strengthening your employee benefits package. From startup tax credits and deductible employer contributions to SECURE 2.0 incentives, businesses can reduce tax liability, offset plan costs, and improve employee recruitment and retention through strategic retirement plan design.

• Claim valuable tax credits for retirement plan startup costs, automatic enrollment, and eligible employer contributions under the SECURE 2.0 Act.
• Deduct employer contributions and qualifying administrative expenses to lower your business’s taxable income.
• Maximize savings by combining multiple tax incentives based on your business size and retirement plan strategy.
• Improve employee retention by offering competitive retirement benefits while reducing overall plan costs.
• Work with a financial advisor and retirement plan specialist to ensure compliance and maximize available tax benefits.

If you’re a business owner weighing the cost of an employer-sponsored retirement plan, the tax advantages alone may change your calculus. Between deductible employer contributions, startup cost credits, and incentives under the SECURE 2.0 Act, offering a qualified retirement plan can meaningfully reduce your tax burden while helping you attract and retain top talent in a competitive market. 

Ohio generally conforms to the federal tax treatment of qualified retirement plans, meaning these benefits apply whether you operate in Columbus, Cleveland, or anywhere in between.

At The Pension Design Group, we’ve spent over two decades helping businesses navigate retirement plan options. Here’s our breakdown of the five tax benefits that matter most.

How We Identified These Tax Benefits

We focused on tax incentives that deliver measurable financial impact, apply to a range of business sizes (especially small businesses with fewer employees), and reflect current law, including provisions from the SECURE 2.0 Act. These selections draw on 25 years of industry experience from retirement plan professionals who work with employers daily on plan design, compliance, and contribution strategy.

5 Key Tax Benefits of Offering Employee Retirement Plans

1. Startup Cost Tax Credits

If you’ve never offered a qualified plan, this is your entry point. Under IRS Code Section 45E, eligible small employers may qualify for a retirement plan startup tax credit. 

• Employers with 50 or fewer eligible employees may claim 100% of eligible startup costs, and employers with 51 to 100 eligible employees may claim 50%, subject to IRS limits. 
• The credit generally applies for the first three years the plan is in effect, and employers can’t both deduct and credit the same startup costs. 
• An additional $500-per-year auto-enrollment credit may also be available for three years if the plan includes a qualifying automatic enrollment feature. 

When combined with the auto-enrollment credit (covered below), total tax credits can reach $16,500 over three years for small businesses. At least one non highly compensated employee must participate to qualify. You also cannot deduct and credit the same costs. So, pick whichever yields the larger benefit.

2. Employer Contribution Tax Deductions

Employer contributions to a 401(k), profit-sharing plan, or other defined contribution plan are generally tax deductible as a business expense, subject to IRS limits. 

• For 2026, deductible employer contributions to a SEP or other defined‑contribution plan are generally limited to 25% of eligible compensation, and the maximum compensation that can be used in the calculation is capped at $360,000.  (This is indexed annually.)
• Deductible contributions may include matching, profit-sharing, safe harbor, and non-elective employer contributions. 

Employer contributions reduce taxable income for businesses directly. Traditional employee salary deferrals into a 401(k) also reduce federal taxable wages, so employees can lower taxable income by contributing pre-tax dollars. Salary reduction contributions are not taxed until withdrawn, and distributions from retirement accounts can be spread over a lifetime. Employees can also create tax-free income with designated Roth accounts, contributing on an after-tax basis.

Contributions can generally be made up to the tax return due date (with extensions), giving you flexibility on timing. For business owners running a profitable LLC or S-corp, this tax deduction can deliver significant tax savings year after year.

3. Automatic Enrollment Tax Credits

Adding an automatic enrollment feature does more than increase participation. It also qualifies small employers for a dedicated tax credit.

• Eligibility threshold: Employers with 100 or fewer employees who earned at least $5,000 in the prior year can claim the credit.
• Annual credit amount: Adding automatic enrollment provides an additional $500 tax credit per year for three years, whether the plan is new or already established.
• EACA requirements: The plan must include an Eligible Automatic Contribution Arrangement. This means proper notices, a uniform default contribution rate, and clear opt‑out provisions.

This credit is modest per year but essentially pays you to adopt a feature that increases retirement readiness among your workforce. Higher participation also helps plans pass nondiscrimination testing more easily.

4. Small Employer Contribution Tax Credits

SECURE 2.0 created a new tax credit for eligible small employers that make matching or non-elective contributions to a new retirement plan. The credit can be worth up to $1,000 per employee and is separate from the employer’s deduction for those contributions 

• The credit covers 100% of qualifying contributions (up to $1,000 per eligible employee) in the first and second years, then phases down: 75% in the third year, 50% in the fourth year, and 25% in the fifth year.
• Only contributions for employees earning under $100,000 count toward the credit.
• For employers with more than 50 employees, the credit is reduced by 2% for each employee above 50.

Tax credits for employer contributions phase out for larger businesses, so this benefit is strongest for the smallest employers. It stacks on top of the contribution deduction, meaning you can both deduct and claim a credit on different portions, per IRS disallowance rules.

5. Administrative Cost Tax Deductions

Running a retirement plan comes with ongoing plan expenses: recordkeeping, audit fees, fiduciary oversight, and educating employees about their investment options. When paid from corporate accounts rather than plan assets, these administrative costs are deductible as ordinary and necessary business expenses.

• 401(k) plan expenses are tax-deductible as business expenses, including plan fees, administrative fees, and consulting costs.
• Paying fees from corporate funds preserves plan assets for participant investment gains, allowing greater tax-deferred growth within retirement accounts.

This approach keeps the employer’s taxable income lower while ensuring that each plan participant benefits from undiminished account balances.

Quick Comparison of Tax Benefits

Small Employer Credits	Businesses ≤50 employees	Five years (phased)	$1,000/employee
Administrative Deductions	Cost-conscious employers	Ongoing	Varies by plan

Choosing the Right Tax Benefits for Your Business

Your employee count determines which credits are available. Employers with 50 or fewer employees get the full rate on startup and contribution credits; between 51 and 100, rates drop; over 100, most credits disappear entirely.

Timeline matters too. Startup cost credits and auto enrollment credits apply during the first three years, while the small employer contribution credit extends through year five. Contribution deductions and administrative cost deductions, by contrast, provide ongoing tax savings indefinitely.

Your priorities should guide the mix:

• Choose startup cost credits if you’re establishing your first retirement plan and want immediate relief.
• Choose contribution deductions if you want ongoing, substantial tax savings that scale with profitability.
• Choose auto enrollment credits if boosting employee participation and retaining good employees is a priority.
• Layer multiple benefits together to maximize total impact, and lean into defined benefit or cash balance plans, or generous 401(k) matching, if long-term retention is the goal.

“Over my 25 years administering in the retirement industry, I’ve seen how layering startup credits, auto enrollment, and generous employer contributions can materially shift a business’s tax burden while keeping good employees engaged in their future.”

— Judd Depew, President, The Pension Design Group

Businesses in Columbus, Ohio and across the state can leverage federal tax incentives to reduce tax liability. For Ohio small business retirement plan options tailored to your situation, local expertise matters.

Final Thoughts

The cumulative impact of these five tax benefits can be significant. A plan sponsor that stacks startup credits, contribution deductions, employer contribution credits, auto enrollment credits, and administrative deductions can offset a meaningful share of total plan costs while building retirement savings for every employee on the team. The optimal combination depends on your specific circumstances: business size, compensation levels, financial goals, and plan type.

This is not general tax advice — every business is different. Working with an experienced retirement plan firm ensures your documents, contribution timing, and your Form 5500 are handled correctly.
