ADP is transforming the way people save for retirement

Every employee’s vision for retirement is different. Each will have questions to answer and decisions to make. At ADP we provide resources to help them get started and take control of their plan.

From financial education to useful tools like the MyADP Retirement Snapshot®1, we help participants understand how to think about the future and design a path to get there.

We make enrollment easy and provide a dashboard that gives each participant a clear view of their plan. Add targeted messaging that provides important information and employees find themselves both more connected to their plan and able to see the benefits of having it.

A wide array of unbiased investment choices

Making the best possible investment decisions for your plan is critical to its success. Whether your advisor is providing investment advisory services or you are considering hiring a third party for this support, ADP offers two distinct options for selecting investments:

  • Our open-fund architecture provides access to over 13,000 nonproprietary investment options from 300+ investment managers. You and your advisor can compare and evaluate funds to find the right candidates for consideration.
  • Our screened investment tiers put simplicity at the forefront by offering fund tiers that have been evaluated and are organized based on ADP’s underwriting criteria.2

In both options, as an independent record keeper, ADP is able to provide investment options without any bias or agenda.

A separate, indirect subsidiary of ADP, Inc., ADP Strategic Plan Services, LLC provides fiduciary investment management services. including the analysis, selection, monitoring, and if necessary, replacement of investment options on behalf of employer-sponsored retirement plans.

Control risk and reduce your fiduciary burden

Today, the Employee Benefits Security Administration, part of ERISA, is actively overseeing, and ensuring the integrity of, the private employee retirement system in the U.S. Sponsoring a retirement plan makes your company responsible for the investment selection and monitoring associated with your plan. That’s often more than most small or midsized companies want to take on. ADP can help you reduce this “investment fiduciary burden”.

  • For plans working with an advisor, Mesirow Financial offers co-fiduciary or investment manager services, depending on the support needed.3
  • For plans not working with an advisor, ADP's affiliate, ADP Strategic Plan Services, LLC, is available.4

Flexible plan designs that are easy to set up

Whether you are looking to establish a new retirement plan or move your plan to ADP, we can help you design a plan that meets the needs of your workforce and answers questions like:

  • At what age should my employees be eligible to participate in the plan?
  • How long should employees work for me before qualifying to join the plan?
  • Should my employees have access to a third-party online investment advisory service?
  • Is a Safe Harbor plan a good choice for my company?
  • Should the plan offer employees a Roth 401(k) option?
  • Would my employees benefit from automatic enrollment?

And when it comes to implementation, we make it easy, with a specialized ADP manager to help ensure the process runs smoothly.

401(k) FAQs

What is a 401(k) plan, and how does it work?

A 401(k) plan allows employees to contribute a portion of their wages to individual retirement accounts. This portion of their wages can be excluded from the employee's taxable income (except for with Roth accounts). Employers can match contributions to employees' accounts to incentivize saving.

What are the different types of 401(k) plans?

There are several types of 401(k) plans available to employers - traditional 401(k) plans, roth 401(k), safe harbor 401(k) plans, solo (k) and SIMPLE 401(k) plans. Different rules apply to each.

Are employers required to offer a 401(k) plan to employees?

Employers generally are not required to offer their employees retirement benefits. However, some states have government-sponsored retirement plans with mandatory participation. In these jurisdictions, eligible employers must enroll their employees in the state program or provide retirement benefits on their own.

Are all employees eligible for a 401(k) plan?

Eligibility is set by the plan sponsor and may vary depending on factors like tenure, age, and employment status to determine who can participate a company’s 401(k) plan.

What are the benefits of offering employees a 401(k) plan?

Offering 401(k) plans benefits employees with automated deposits, potential employer matches, and tax savings. Employers benefit by attracting talent, boosting employee satisfaction, possibly qualifying for tax incentives for their business, and showing commitment to employee financial wellness.

What are the responsibilities of a 401k plan administrator?

401(k) plan administrators are responsible for the day-to-day operations and administrative tasks to ensure that retirement plans are compliant with regulations and help everyone on the plan enroll and save for retirement. They work with legal documents, analyze, test, and monitor the plan's operation.
