Executive Summary
Most employers change recordkeepers rarely, so the choice is less a software purchase than a long relationship: pick the provider your participants, your payroll team and your plan committee will still be well served by years from now.
A 401(k) recordkeeper keeps the books for the plan. It tracks each participant's contributions, investments, loans and distributions, runs the participant website and call center, takes contribution data from payroll, and produces what the plan needs for nondiscrimination testing and its annual Form 5500 filing. For most employees it is the only part of the plan they ever see.
The market has consolidated through a long series of acquisitions. The largest providers now serve plans of every size, insurance-company and specialist providers work largely through advisors and third-party administrators, and a newer group of payroll-integrated providers concentrates on small businesses. Which group fits depends mostly on the size of the plan, how complex its design is, and whether an advisor and administrator are already in place.
Choosing a recordkeeper is a fiduciary decision. ERISA requires plan fiduciaries to act prudently and to make sure the fees the plan pays for services are reasonable, and Department of Labor rules require the recordkeeper to disclose its compensation to the plan. A documented review of the incumbent, and a request for proposals when the review warrants one, is the record that the process was prudent. This guide is built to support that process.
Why the Recordkeeper Choice Matters Now
The SECURE 2.0 Act moved a great deal of plan design into the recordkeeper's systems. It requires most newly established 401(k) plans to enroll eligible employees automatically, changes how catch-up contributions work for higher earners, and allows optional features such as emergency savings accounts linked to the plan and employer matching contributions on student loan payments. Each of these is only available if the recordkeeper has built and operates it, and providers have not adopted every optional feature on the same timetable.
Fees have become a fiduciary risk as well as a cost. Lawsuits alleging excessive recordkeeping fees have been brought against plan sponsors of many sizes, and the question they turn on is usually whether the committee monitored fees and compared them with the market, rather than whether the fee was the lowest available. A periodic benchmarking exercise or request for proposals is a protection in itself, whatever it concludes.
The recordkeeper also holds the most sensitive data the employer shares with any vendor: identities, account balances, bank details and beneficiaries. That makes its security controls, its fraud protections and its policy on using participant data to market its own products, such as rollover IRAs and wealth management, part of the selection rather than an afterthought.
Small employers have more choice than they used to. Payroll-integrated providers such as Human Interest and Guideline have made a plan practical for businesses that previously had none, and state auto-IRA mandates have pushed more small employers to choose between a state program and a 401(k) of their own.
Bundled vs. Unbundled Recordkeeping
The first decision is not which provider but which arrangement. In a bundled plan one provider handles recordkeeping, plan administration and compliance testing, and often supplies the investments. In an unbundled plan the employer, usually with an advisor, chooses the recordkeeper, a third-party administrator (TPA) and the investment menu separately. Many providers offer both, so ask each finalist which arrangement it is proposing.
| Dimension | Bundled (one provider) | Unbundled (recordkeeper, TPA and advisor) |
|---|---|---|
| Who does what | Recordkeeping, administration and testing from one provider, often with its own investments | Recordkeeper, TPA and advisor each chosen and contracted separately |
| Investment menu | Often weighted toward the provider's own funds; ask how open the menu can be | Open menu selected with the advisor |
| Fees | One schedule, but its components can be harder to separate and benchmark | Each provider's fee is stated separately and easier to compare |
| Plan design | Standard designs handled well; complex designs may not be supported | A TPA can support complex designs such as cross-tested profit sharing |
| Accountability | One point of contact when something goes wrong | Responsibilities split across firms; document who owns each task |
| Sponsor effort | Lower | Higher, because three firms have to be coordinated |
What to Evaluate in a Recordkeeper
Every recordkeeper can process contributions and produce statements. The differences that matter after the contract is signed are in how much work the plan creates for your payroll and HR teams, how well participants are served, and how much of the compliance burden the provider actually carries. The areas below are listed roughly in the order sponsors tend to feel them.
| Area | What to Evaluate | Questions to Ask |
|---|---|---|
| Payroll integration | How contribution and census data reach the plan, and how errors are caught | Do you integrate directly with our payroll provider? Who fixes a rejected file, and how quickly? |
| Participant experience | Website, mobile app, enrollment flow, education and call center | Can we use a test account before deciding? What languages and hours does the call center cover? |
| Compliance and testing | Nondiscrimination testing, Form 5500 support, required notices and plan document maintenance | Which of these do you perform, which does our TPA, and who is liable for an error? |
| Plan sponsor tools | Sponsor dashboard, reporting, approvals for loans and distributions, fiduciary reporting | Show us the monthly reports our committee would receive. |
| Investments and advice | Menu flexibility, target-date options, managed accounts, brokerage window | Can we use funds you do not manage, and how does that change the fee? |
| Service model | Relationship manager, service tier for our plan size, service agreement remedies | Who is our day-to-day contact, and what does the agreement commit to when service falls short? |
| Security and data use | Controls reporting, fraud protection, account takeover response, marketing to participants | Will you share your independent controls report? Do you use participant data to market other products? |
| Fees and transparency | How each fee is charged and disclosed, revenue sharing, transaction fees | Give us one total plan cost, broken down by component, for our actual participant count and assets. |
Vendor Landscape
The six providers below are a starting shortlist across the main groups of the market, not a ranking of all of it. John Hancock, Voya, T. Rowe Price, Transamerica, Schwab and many regional and advisor-focused recordkeepers are also worth considering, depending on plan size and on whether an advisor is involved. Every consideration below is a question to put to that provider, because the answer depends on your plan.

EmergingHow Recordkeeping Is Priced
Recordkeeping is rarely priced as a single line. Fees can be charged per participant, as a percentage of assets, as a flat plan-level fee, or as a combination, and they can be paid by the employer, deducted from participant accounts, or covered partly by revenue sharing from the plan's funds. Asset-based fees grow with the plan even when the work does not, which is why larger plans often negotiate a fixed per-participant fee instead. The only fair comparison is total plan cost for your actual participant count and assets, broken down by component, from every finalist.
| Fee Component | How It Is Charged | Who Usually Pays | What to Ask |
|---|---|---|---|
| Recordkeeping and administration | Per participant, percentage of assets, flat plan fee, or a mix | Employer, participants, or both | Is the fee fixed per participant, and how does it change as assets grow? |
| Revenue sharing | Paid from fund expenses back to the recordkeeper | Participants, through fund expenses | Is any revenue sharing credited back to participants, and how is it disclosed? |
| Investment expenses | Each fund's expense ratio | Participants | Are lower-cost share classes or collective trusts available for our plan? |
| Participant transactions | Per loan, distribution or domestic relations order | Usually the participant involved | Which transactions carry a fee, and can the employer choose to pay them? |
| Advisory and managed accounts | Percentage of assets or a flat fee; managed accounts often opt-in | Participants or employer | Is advice included, and who acts as fiduciary for it? |
| Conversion and termination | One-time charges on joining or leaving | Employer or plan | Will you cover the costs of moving from our current provider, and what does leaving cost? |
Changing Recordkeepers: The Conversion
A conversion commonly takes several months from selection to go-live, and most of its risk sits in two places: payroll data and the blackout period. The phases below are the usual sequence; the new recordkeeper should supply a dated plan for each before you sign.
Review the incumbent, issue a request for proposals to a shortlist, hold finalist presentations and reference calls, and document the committee's reasoning. Benchmarking the incumbent's fees is often part of the same exercise, and sometimes its conclusion.
Negotiate the service agreement and fee schedule, review the plan document and any amendments the new provider requires, confirm the investment menu, and agree who performs each compliance task.
Map participant, loan and beneficiary records from the incumbent, set up and test the payroll connection, and reconcile census data. Errors found here are cheap; errors found after go-live are not.
Participants are notified in advance, as federal rules require, then a blackout period begins in which they cannot change investments or take loans and distributions while records and assets move. Keep it as short as the providers can safely manage.
Reconcile balances against the incumbent's final records, check the first payroll cycles end to end, track participant calls and complaints, and hold the new provider to the service agreement from the first month.
Selection Checklist & RFP Questions
Use these questions in a request for proposals and in finalist meetings. They cover what tends to go wrong after the contract is signed, which is rarely what the sales presentation is about.

Frequently Asked Questions
How do you choose a 401(k) recordkeeper?
Decide first whether you want a bundled arrangement, where one provider handles recordkeeping, administration and often investments, or an unbundled one with a separate third-party administrator and advisor. Then compare a shortlist on participant experience, payroll integration, compliance support, service model, data security and total plan cost, using a written request for proposals and references from plans of your size. Document the process: choosing and monitoring a recordkeeper is a fiduciary decision under ERISA.
How are 401(k) recordkeeping fees charged?
Recordkeeping fees are charged per participant, as a percentage of plan assets, as a flat plan-level fee, or as a combination, and they can be paid by the employer, deducted from participant accounts, or covered in part by revenue sharing from the plan's investments. Individual transactions such as loans and distributions often carry their own fees. Compare proposals on total plan cost, including investment expenses and advisory fees, not on the recordkeeping line alone.
Which 401(k) recordkeepers have the best technology and security for plan sponsors?
There is no single best choice; it depends on the plan. Ask each finalist for a live demonstration of the participant and sponsor websites, how payroll data reaches the plan, and a copy of its independent controls report. The Department of Labor has published cybersecurity guidance for plan fiduciaries, including tips for hiring a service provider, which works well as a question list. Ask too how the provider protects participants against account takeover and what it will reimburse if a fraudulent distribution occurs.
How do 401(k) recordkeepers compare on customer service?
Service depends less on the provider's brand than on the service tier your plan's size earns. Ask who your day-to-day contact will be, how participant calls are handled, what the service agreement commits to and what happens when it is missed, and speak to references from plans of similar size that converted recently.
How long does it take to change 401(k) recordkeepers?
A conversion commonly takes several months from signing to go-live: contracting and plan document review, data mapping and payroll setup, then a blackout period while records and assets move, during which participants cannot change investments or take loans and distributions. Federal rules require that participants be told about a blackout period in advance, so the timeline has to leave room for that notice.
How We Evaluate
We write these guides for people running a software selection. This one covers 6 platforms and should save you weeks of research, but it will not replace your own reference calls and a proof of concept.
We assess vendors from their published product documentation and from what practitioners report about running them. The positions and scores here are our opinion. No vendor supplied them and nobody audited them. Use them to build a shortlist, then go and test it yourself.
The criteria weights are ours as well. We chose them for this category and publish them so you can see what we valued, and weight things differently if your situation calls for it.
No vendor pays to appear in this guide or to be described the way it is. Spotlight placements alongside our guides are paid and labeled Sponsored, and they change nothing about the evaluation.
Last reviewed October 2026. Enterprise software moves quickly and pricing is negotiated rather than listed, so parts of this will age. If we have something wrong, tell us and we will fix it. That goes double if you work for a vendor we cover.
