State Mandates Expand Retirement Administration
Gusto
State mandates turn retirement plans from a nice to have benefit into a compliance workflow that starts inside payroll. Once an employer in California, New York, or another mandate state has to either join the state program or offer a private plan, a bundled Gusto and Guideline product becomes an easy default because payroll data, deductions, eligibility, and filings can all run in one system.

The market is no longer just demand from employers trying to recruit talent. As of January 1, 2026, 20 states had enacted retirement savings programs for private sector workers, and 17 state programs were open to eligible employers and workers, which creates a growing stream of legally prompted buyers.

SECURE 2.0 made the low end of the market easier to serve. Guideline built Starter K for smaller and more hourly businesses, with lighter compliance requirements and pricing of $39 plus $4 per active participant per month, versus $89 plus $8 for its core plan, while keeping similar gross margins because support work is lower.

This is also a distribution shift in favor of payroll platforms. Digital 401(k) providers win when they can pull clean employee and pay stub data directly from payroll, and payroll partners raise retention and ARPU when a retirement product is attached. Human Interest and Guideline both scaled through these payroll integrations before Gusto moved to own the stack more directly.
The next phase is a tighter bundle where payroll platforms capture more of the retirement value chain themselves. As more mandate states go live and more very small employers need a compliant option, the winners will be the providers that make plan setup feel like turning on another payroll setting, then expand from 401(k)s into adjacent savings and benefits products.
