What Is a Small Business 401(k) Plan?

A small business 401(k) plan is a tax-advantaged retirement savings account that allows both employees and employers to contribute funds toward retirement. These plans operate under specific IRS guidelines but offer tailored solutions for businesses with fewer employees.

Small business 401(k) plans function similarly to those at larger corporations but typically come with simplified administration requirements and potentially lower costs. They allow participants to invest pre-tax dollars, reducing current taxable income while building retirement savings that grow tax-deferred until withdrawal.

How Small Business 401(k) Plans Work

Small business 401(k) plans operate through payroll deductions where employees contribute a percentage of their salary into individual retirement accounts. Employers can choose to match contributions based on predetermined formulas, such as matching 50% of employee contributions up to 6% of their salary.

Plan administrators handle investment selections, compliance requirements, and participant education. Employees direct their investments among available options, typically including mutual funds, target-date funds, and sometimes company stock. Annual contribution limits are set by the IRS, with additional catch-up contributions permitted for employees over 50.

Small business owners should understand that these plans require annual testing to ensure they don't disproportionately benefit highly-compensated employees. However, certain plan designs like Safe Harbor 401(k)s can eliminate some testing requirements while providing additional benefits to employees.
