Choosing the right 401(k) investment advisor is one of the most important decisions you can make as a small business owner. Your retirement plan affects your employees’ financial futures, your legal obligations, and your ability to compete for top talent. Yet many business owners approach this decision without a clear strategy. This guide breaks down exactly what to look for so you can find an advisor who truly works for you and your team.
If you’re just getting started or reconsidering your current plan, explore how Able & Strong Advisors supports small businesses with tailored retirement planning solutions.
Fiduciary Commitment
The single most important quality to look for in a 401(k) advisor is whether they act as a fiduciary. A fiduciary is legally required to put your interests — and your employees’ interests — first. Not every financial advisor meets this standard. Under the “suitability” standard, advisors can recommend options that meet basic requirements but aren’t required to prioritize your or your employees’ best interests.
Under ERISA (Employee Retirement Income Security Act), plan sponsors — that’s you, the business owner — are already fiduciaries to your employees. That means you carry personal legal liability if the plan is mismanaged. A fiduciary advisor who shares that responsibility is not just helpful; it can protect you from serious financial and legal exposure.
Advisors can serve in one of two capacities. A 3(21) fiduciary provides investment advice while you retain final decision-making authority. A 3(38) fiduciary takes on full discretionary investment management, which shifts more of the liability off your plate. Ask any advisor upfront: “Are you a fiduciary? In what capacity?” A clear, confident answer is what you’re looking for.
Fee Transparency
Fees play an important role in long‑term retirement outcomes, yet they’re often misunderstood. Every 401(k) plan includes some costs, such as advisor fees, recordkeeping fees, and fund expense ratios. The key is understanding how these fees work and ensuring they’re reasonable for the value your plan provides.
A trustworthy advisor will explain every fee in plain language. They’ll help you understand the total plan cost and benchmark it against industry norms. Ask for a full fee disclosure, including any compensation they receive from fund companies. If an advisor is reluctant to share this, or if the explanation feels vague, it’s worth asking more questions.
The Department of Labor requires plan sponsors to review fees regularly as part of their fiduciary duty. An advisor who makes this process easy — by providing transparent, organized documentation — is an advisor worth keeping.
SECURE 2.0 Knowledge
The retirement landscape shifted significantly with the passage of the SECURE 2.0 Act. In 2025 alone, several mandatory provisions took effect, including expanded eligibility for long-term part-time workers after two years of service and new auto-enrollment requirements for most employer-sponsored plans. These are not optional — they’re legal obligations.
A knowledgeable advisor stays current on these changes so you don’t have to. They’ll help you understand which provisions are mandatory, which are optional enhancements you can take advantage of, and how the law affects your specific plan design. SECURE 2.0 also introduced valuable tax credits for small businesses starting or improving a 401(k) — up to $5,000 per year for the first three years. A good advisor helps you make the most of every opportunity your plan offers.
Investment Expertise
Not every 401(k) advisor is an investment expert, and not every investment advisor understands how retirement plans actually work. The right advisor brings both financial insight and plan‑level expertise. Your plan’s investment lineup directly impacts how well your employees save and grow their retirement wealth over time. An investment menu with high‑cost or underperforming funds can limit employees’ long‑term growth potential.
Look for an advisor who can build a diversified, cost-effective fund lineup suited to your workforce’s age range and risk tolerance. They should also conduct regular investment reviews — at least annually — to make sure the lineup remains competitive and compliant. Ask how they select and monitor funds, and whether they use an investment policy statement (IPS) to guide decisions. An IPS is a sign of a structured, accountable approach.
Employee Education Support
Offering a 401(k) plan is only half the equation. If your employees don’t understand it, they won’t use it — and you lose the retention and morale benefits you were hoping for. Research shows that nearly 73% of employees don’t feel fully educated about their company’s benefits, including their 401(k). That’s a significant participation gap that better education can close.
A great advisor doesn’t just manage the plan — they help your employees understand it. This can include enrollment meetings, one-on-one consultations, educational materials, and ongoing communication throughout the year. When employees feel supported and informed, they participate more, contribute more, and feel more loyal to the employer who helped them get there.
This matters for recruitment, too. A large percentage of employees say a 401(k) or defined contribution plan is a must-have benefit. A well-run, well-communicated plan signals to job candidates that your company is serious about their long-term well-being.
Small Business Experience
Small businesses face challenges that large corporations simply don’t. Tight budgets, lean HR teams, and fewer employees to spread fixed plan costs across — these realities require an advisor who understands your world. Despite this, only 46% of employers with fewer than 100 employees offer a 401(k) or similar plan, compared to 92% of large employers. That gap exists partly because small business owners don’t always know where to start.
An advisor with a strong track record serving small businesses will know how to design a plan that fits your size, budget, and workforce. They’ll help you avoid overengineered plans with features you don’t need — and make sure the plan you do have is running as efficiently as possible. Experience with small businesses means less hand-holding from you and more proactive guidance from them.
