Recordkeeper vs Advisor vs TPA: Overview
What is a recordkeeper?
A recordkeeper is the firm responsible for maintaining participant-level account data in your 401(k) plan. This includes tracking contributions, investment elections, account balances, loan transactions, and distributions. The recordkeeper also typically hosts the online platform where your employees log in to view statements, change investment allocations, and manage beneficiary designations.
Recordkeeper key benefits
- Account tracking: Maintains real-time records of each participant’s contributions, earnings, and vesting status.
- Transaction processing: Handles loans, hardship withdrawals, rollovers, and required minimum distributions.
- Participant portal: Hosts the website or app where employees access statements and update investment elections.
- Quarterly statements: Generates and distributes account balance reports to all plan participants.
- Data integration: Connects with payroll systems to reconcile contribution uploads and catch discrepancies.
Recordkeeper pros and cons
Pros:
- Offers direct participant access to account information and self-service tools around the clock.
- Automates transaction processing for contributions, loans, and distributions at the participant level.
- Generates standardized reports that help plan sponsors monitor plan activity at a glance.
Cons:
- Recordkeepers typically do not perform nondiscrimination testing or prepare Form 5500 filings, so a TPA is often needed alongside.
- Participant-facing platforms vary by firm, and some offer limited customization for plan-specific rules.
- Recordkeeper data may require independent reconciliation to confirm accuracy against payroll and census records.
What is a plan advisor?
A plan advisor is a financial professional who helps plan sponsors select and monitor investments, review plan strategy, and fulfill certain fiduciary obligations. Depending on the engagement, a plan advisor may serve as a 3(21) investment advisor or a 3(38) investment manager under ERISA. Advisors also coordinate participant education sessions and benchmark fees against industry standards.
Plan advisor key benefits
- Investment oversight: Selects, monitors, and updates the fund lineup based on performance and suitability criteria.
- Fiduciary guidance: May assume fiduciary responsibility for investment decisions under a 3(21) or 3(38) arrangement.
- Fee benchmarking: Reviews plan fees and compares them to peer plans of similar size and structure.
- Participant education: Conducts enrollment meetings, one-on-one sessions, and ongoing financial wellness programs.
- Plan strategy: Advises on plan design changes, auto-enrollment, auto-escalation, and Roth contribution options.
Plan advisor pros and cons
Pros:
- Brings specialized investment knowledge that helps plan sponsors build a diversified fund menu.
- Can accept fiduciary responsibility for investment-related decisions, reducing sponsor liability in that area.
- Supports participant engagement through ongoing education, which can improve contribution rates.
Cons:
- Plan advisors do not typically handle compliance testing, plan document maintenance, or Form 5500 preparation.
- Advisory services focus on investments; plan administration tasks often require a separate TPA relationship.
- Advisors with general wealth management practices may not have deep expertise in retirement plan regulations.
What is a TPA?
A Third-Party Administrator (TPA) is a firm that manages the technical administration and compliance functions of your retirement plan. The TPA handles plan design, ERISA compliance testing, contribution allocations, Form 5500 preparation, and plan document maintenance. TRA operates as a specialized TPA that partners with plan sponsors and plan advisors to ensure every plan runs accurately and meets all regulatory requirements.
TPA key benefits
- Plan design: TRA creates customized retirement plan designs tailored to your business goals, employee demographics, and contribution strategy.
- Compliance testing: Performs annual ADP/ACP, top-heavy, and coverage tests to confirm your plan meets IRS and DOL requirements.
- Form 5500 preparation: Prepares and reviews your annual filing so it is accurate and submitted on time.
- Plan document maintenance: Drafts, amends, and updates your plan document to reflect current law and regulatory changes.
- Contribution allocation: Calculates employer match, profit sharing, and forfeiture allocations with accuracy verified by independent reconciliation.
TPA pros and cons
Pros:
- TRA reduces your compliance risk by managing nondiscrimination testing, regulatory filings, and plan document updates proactively.
- TRA assigns a dedicated team that knows your plan and anticipates your administrative needs before deadlines arise.
- TRA is platform-neutral and partners with any recordkeeper or investment firm your plan advisor recommends.
Cons:
- A TPA does not manage participant investments or host the participant-facing online platform, so a recordkeeper is still required.
- Employers unfamiliar with unbundled service models may initially need guidance on how TPA and recordkeeper responsibilities are divided.
- Coordination between TPA, recordkeeper, and advisor requires clear communication protocols, which TRA supports through proactive outreach.
Recordkeeper vs Advisor vs TPA: In-Depth Comparison
Compliance and regulatory administration
A TPA is responsible for the technical compliance work that keeps your plan qualified under IRS and DOL rules. This includes nondiscrimination testing, regulatory deadlines, and plan document updates. TRA, as the nation’s largest independently owned, privately held TPA, reviews every plan for accuracy and compliance through a dedicated quality team.
Recordkeepers generally do not perform compliance testing. Plan advisors may flag potential issues, but they rely on the TPA for testing and corrections. The TPA is the firm specifically trained to navigate this area.
Investment oversight and fiduciary roles
Plan advisors take the lead on investment selection, monitoring, and fiduciary oversight under ERISA sections 3(21) and 3(38). Recordkeepers host the investment platform and execute trades but do not make investment recommendations or assume fiduciary responsibility for fund choices.
TRA complements the advisor’s role by offering 3(16) fiduciary services that handle administrative fiduciary duties. According to a proposed DOL rule on fiduciary duties published in 2026, plan sponsors face increasing scrutiny on how they select and monitor investment options, making coordinated fiduciary support from both an advisor and a TPA more important than ever.
Plan design and customization
A TPA is typically the firm that designs and documents your plan’s specific features, from eligibility rules and vesting schedules to safe harbor formulas and profit sharing structures. Plan advisors often recommend design changes, but the TPA translates those recommendations into a compliant plan document.
Recordkeepers operate the plan on the platform but do not customize plan provisions. TRA partners with plan advisors to design plans that maximize contributions for owners while meeting employee retention goals.
Participant experience and account access
Recordkeepers own the participant experience. They host the website, process transactions, and generate quarterly statements. When an employee wants to check a balance, request a loan, or change an investment election, the recordkeeper’s platform is the point of contact.
Plan advisors contribute to the participant experience through education sessions and enrollment support. TRA ensures that behind the scenes, eligibility determinations, contribution calculations, and distribution approvals are processed accurately and on time.
Error correction and plan audits
When operational errors occur in a 401(k) plan, the TPA is the firm with the expertise to identify, document, and correct them. This includes correcting common 401(k) errors such as missed deferrals, incorrect eligibility determinations, and failed compliance tests.
Recordkeepers may flag discrepancies at the transaction level, and advisors may identify issues during fee benchmarking or plan reviews. TRA brings over 27 years of retirement plan expertise to error correction and audit preparation, reducing your exposure to penalties.
