Frequently asked questions
Less than you'd think. Gusto 401(k) is built on a platform that already powers 40,000+ small business plans, so most of the admin runs automatically. Payroll syncs seamlessly, contributions and deductions are handled for you, and compliance happens in the background. Like every Gusto product, it was made with the small business owner in mind, so offering retirement feels as simple as running payroll.
Setting up a Gusto 401(k) can take as few as 9 minutes. And then it usually takes about 40 days until first contributions are made. Since all Gusto 401(k) plans come with automatic enrollment, eligible employees can’t be auto-enrolled in your plan until 30 days after they receive a helpful notice of the new benefit. That could give them enough time to opt out before the plan begins.
Once everything is set up, your team will be guided through a seamless onboarding process, while you can sit back and relax.
You may be required to. More than 15 states now require certain employers—including some with as few as one employee—to offer a retirement savings benefit. Requirements vary by state, so check whether your business is affected here.
Yup. We work with businesses of any size, whether you're a solopreneur, just hired your first employee, or lead a team of thousands. We’re built to grow with you every step of the way.
