Discover what's behind this trend and how your business may benefit from an introductory benefit plan._ Ultrasmall businesses with one to nine employees represent the fastest-growing segment of retirement plan sponsors today. According to a recent article by the [Plan Sponsor Council of America](https://www.psca.org/news/psca-news/2025/7/micro-401k-plan-market-growth-to-increase-rapidly/), nearly 150,000 new 401(k) plans launched between 2018 and 2023, with two-thirds added in 2021 and 2023 alone. By 2029, micro plans are projected to account for 92% of all 401(k) plans. ## What's driving this growth? Legislative changes have helped ease start-up costs and ongoing expenses, while also making plans easier to manage. _Tax incentives:_ [SECURE 2.0](https://www.adp.com/spark/articles/2023/03/secure-20-new-small-business-tax-incentives-for-retirement-plans.aspx) legislation provides a tax credit to cover 100% of start-up administrative costs for the first three years of a new plan for eligible employers with 50 or fewer employees. It also provides tax credits for offering an employer matching contribution and for automatic enrollment. Plus, participants who make pre-tax 401(k) deferrals lower their taxable income and may be eligible for a tax credit. _Pooled employer plans ([PEPs](https://www.adp.com/spark/articles/2025/12/what-is-a-pep-understanding-pooled-employer-plans.aspx)):_ Under SECURE 2.0, PEPs now qualify for tax incentives when established as a new plan. This collective plan structure is a great option for smaller companies to reduce costs, simplify management and minimize fiduciary risks. _State mandates:_ More than 50% of U.S. states have [proposed or active legislation](https://www.adp.com/resources/state-mandated-retirement-plans.aspx) in place, mandating that certain private-sector businesses participate in state-facilitated programs or sponsor a private plan. This is prompting many employers to establish competitive private plans that better suit their needs and goals. ## Retirement plans have a big impact on small employers Retirement plans deliver significant value to ultrasmall businesses competing for talent by providing high-value benefits such as those listed below: #### Recruiting and retention A retirement plan serves as a powerful tool to attract and retain motivated employees with the financial benefits they want and need. #### Employee engagement Retirement benefits can increase overall employee engagement, productivity and satisfaction by helping to ease financial worries. #### Simplified administration From [embedded](https://www.adp.com/spark/articles/2025/10/embedded-vs-integrated-know-your-retirement-plan-technology.aspx) payroll integration to automatic enrollment, today's retirement solutions offer the technology to manage and maintain plans with confidence, reduce errors and meet employees' goals. #### Financial wellness Providing a retirement plan helps employees work toward overall [financial wellness](https://www.adp.com/spark/articles/2025/11/moving-beyond-the-match-the-employers-role-in-retirement-security.aspx), showing employees that their employers care about their retirement readiness and financial security. ### Retirement benefits made simple For ultrasmall employers ready to offer a plan, ADP offers a smart, affordable solution.
