Offering a retirement benefit used to feel like something only large corporations could afford. That assumption is costing small and mid-sized businesses real talent. Today, more than half of employees say a retirement plan is a must-have — not a nice-to-have — when evaluating a job offer. If your company isn't offering one, or if you're not sure whether the plan you have is actually the right fit, this guide will help you make a confident, informed decision.

Why Your Choice of Retirement Plan Matters More Than You Think

Choosing an employer-sponsored retirement plan isn't just a benefits checkbox. The plan type you select determines your administrative burden, your annual contribution limits, your tax advantages, and how attractive your offer looks to top candidates. A plan that works brilliantly for a solo founder may create compliance headaches the moment you hire your tenth employee. Getting this decision right from the start — or revisiting it as your company grows — saves money, reduces IRS risk, and strengthens retention.

The Most Common Small Business Retirement Plans Compared

There is no single best retirement plan for every business. The right choice depends on your headcount, cash flow predictability, and how much you want to contribute on behalf of employees. Here is a practical breakdown of the most widely used options:

401(k) Plans

The traditional 401(k) is the gold standard for employee retirement benefits and the most recognizable plan name in the market. Employees contribute pre-tax dollars from each paycheck, and employers can choose to match contributions. For 2024, employees can contribute up to $23,000 (or $30,500 if they are 50 or older). A 401(k) for small business is more accessible than ever, thanks to third-party administrators and bundled platforms that handle compliance testing, recordkeeping, and IRS filings. The SECURE 2.0 Act also introduced meaningful tax credits that can offset setup and administration costs for new plans, making this a strong option even for lean organizations.

SIMPLE IRA

The SIMPLE IRA (Savings Incentive Match Plan for Employees) is designed for businesses with 100 or fewer employees. It is easier to administer than a 401(k) and requires no complex nondiscrimination testing. Employees can contribute up to $16,000 in 2024, and employers are required to make either a matching contribution of up to 3% of compensation or a flat 2% nonelective contribution. The mandatory employer contribution is the trade-off for its simplicity — if cash flow is unpredictable, that obligation can feel rigid during a slow quarter.

SEP-IRA

The SEP-IRA (Simplified Employee Pension) is ideal for self-employed individuals and very small businesses, particularly those with variable income. Employers can contribute up to 25% of an employee's compensation, up to $69,000 in 2024. There are no employee contributions — only employer contributions — which means the entire funding burden falls on the business. This structure works well for profitable years but offers no employee engagement component since workers cannot defer their own pay into the plan.

Solo 401(k)

If you are a business owner with no full-time employees other than a spouse, the Solo 401(k) offers the highest potential contribution limits of any retirement savings plan. You contribute both as employee and employer, allowing combined contributions up to $69,000 in 2024. Once you hire W-2 employees, you will need to transition to a plan that covers your team.

Key Factors to Evaluate Before You Decide

Before selecting a retirement plan, work through these practical questions:

  • How many employees do you have, and how many do you expect to hire? A SIMPLE IRA has a hard cap at 100 employees. If rapid growth is in your plans, a 401(k) scales more cleanly.
  • How much can you afford to contribute as an employer? SIMPLE IRAs require mandatory contributions. SEP-IRAs give you flexibility to contribute nothing in a bad year. A 401(k) match is discretionary unless otherwise promised.
  • How much administrative capacity does your HR team have? 401(k) plans require annual nondiscrimination testing and Form 5500 filings. If you lack in-house HR expertise, outsourcing plan administration to an ASO like Nomad Partners can eliminate that burden entirely.
  • What matters most to your employees? If you want workers actively engaged in saving — and if you want the recruiting visibility that comes with a strong 401(k) match — a traditional 401(k) is hard to beat.
  • Are you eligible for the SECURE 2.0 tax credit? Businesses with fewer than 100 employees starting a new retirement plan may qualify for up to $5,000 per year in tax credits for three years, plus additional credits for employer contributions.

Avoiding Common Retirement Plan Mistakes

Even well-intentioned employers make costly errors when setting up or managing an employee retirement plan. The most frequent pitfalls include failing to update plan documents when the law changes, missing required employer contributions under a SIMPLE IRA, and neglecting to run timely nondiscrimination tests on a 401(k). These oversights invite IRS penalties and erode employee trust. Working with an experienced HR administration partner keeps your plan documents current, your filings on time, and your employees informed at every enrollment cycle.

Turn Your Retirement Plan Into a Recruiting Advantage

A competitive retirement benefit is not just a financial tool — it is a signal to candidates that your company invests in their long-term wellbeing. When paired with a clear communication strategy during onboarding and open enrollment, even a modest employer match can meaningfully differentiate your offer in a crowded hiring market. The businesses that win talent are the ones that treat benefits as a strategic asset, not an administrative afterthought.

The right retirement plan is the one that fits your business today and scales with you tomorrow — without creating compliance risk along the way.
