Why You Shouldn’t Let Your Payroll Company Manage Your 401(k)

Having one company handle both your payroll and your 401(k) might sound convenient—but convenience can come at a cost. When payroll providers step into retirement plan management, it often creates bigger problems, not solutions.

At Baron Payroll, we’ve seen too many business owners learn the hard way that “bundled” doesn’t mean better.

Here’s why you’ll want to keep payroll and 401(k) management separate.

1. No Fiduciary Responsibility

Your payroll provider isn’t a fiduciary for your 401(k). That means if they make a mistake, the liability falls on you—the business owner. Compliance errors with retirement plans aren’t just headaches; they can lead to fines, penalties, and even personal liability.

2. Hidden Fees and Higher Costs

Bundled services often look cheaper on paper, but those “convenience packages” usually come with higher investment costs or buried administrative fees. Independent 401(k) specialists are transparent about costs and can often save you and your employees money in the long run.

3. Cookie-Cutter Plans

Payroll providers typically offer the same plain 401(k) setup to every business. That might be fine for some, but it ignores opportunities for tax savings or creative plan design—like profit-sharing or tiered contributions—that could make a real difference for your company and employees.

4. Limited Support

With payroll companies, you’re often just a number. Need help with compliance testing or a tricky eligibility question? Good luck getting someone who knows retirement law on the phone. Independent 401(k) providers specialize in this space, so you get direct, knowledgeable support when it matters.

5. Compliance Risks

Retirement plans come with layers of compliance—nondiscrimination testing, annual filings, contribution deadlines, and more. Payroll providers are not experts in this area. Mistakes here don’t just create paperwork problems—they can trigger expensive IRS or Department of Labor penalties.

6. Integration ≠ Expertise

Many payroll companies push “all-in-one” systems that sync contributions automatically. That sounds good, but integration doesn’t equal oversight. Just because the numbers flow from one system to another doesn’t mean they’re right—or compliant.

What To Do Instead

The smarter approach is to separate payroll from retirement plan management:

Work with a 401(k) specialist or TPA (Third-Party Administrator). They can design a plan tailored to your business, manage compliance, and in many cases share fiduciary responsibility.
Use payroll integration without giving up control. Data can flow between systems for efficiency, while your 401(k) expert ensures compliance and proper plan design.
Prioritize transparency and accountability. Independent providers break down all fees, give you a dedicated contact, and monitor your plan year-round.

The Bottom Line

Your payroll company should do payroll—and do it perfectly. But your 401(k) deserves a specialist who can protect you from compliance risks, reduce hidden costs, and create a plan that actually works for your business and employees.

At Baron Payroll, we stick to what we do best: payroll, timekeeping, and compliance. For retirement plans, we’ll point you to specialists who can protect your business and your employees’ future.
