Comparison Table
CLA
enterprise_vendorProvides employee benefit plan audits, including defined contribution plan engagements.
Engagement documentation links plan testing evidence directly to audit conclusions to streamline review and prior-year follow-up.
CLA’s 401k audit delivery focuses on execution of plan audit work that supports an auditor’s report and the independent qualified public accountant position. Audit testing workflows typically cover plan financial statements support and reporting package reconciliation activities needed for the Form 5500 annual report. The engagement model emphasizes documented walkthroughs and traceable workpapers that make prior-year issues easier to track through follow-up.
A tradeoff is that CLA’s process depth can add more internal coordination effort for plan sponsors than lighter limited-scope approaches. CLA fits best when there is enough lead time to assemble participant census, payment and eligibility inputs, and investment information for audit testing.
- +Structured workpapers that connect testing steps to audit conclusions
- +Audit execution aligned to AICPA employee benefit plan standards
- +Clear audit planning that reduces rework during fieldwork
- +Consistent follow-up documentation for prior-year findings
- –Requires more sponsor time to support data pulls and confirmations
- –May feel heavier than limited-scope audit engagements for smaller plans

Best for: Fits when plan sponsors need full audit execution with strong documentation discipline and coordinated reporting support.
EisnerAmper
enterprise_vendorAudits employee benefit plans and supports ERISA financial reporting obligations.
Coordinated audit project management that organizes sponsor data requests across participant, payroll, and investment inputs.
EisnerAmper is a strong fit for organizations that need audit staffing depth, documented fieldwork, and consistent reporting outputs for plan sponsors. The engagement process typically includes planning for contribution and payroll mapping, controls walkthroughs for plan administration processes, and substantive testing tied to the plan’s recordkeeping. Teams that operate multiple service lines also tend to value the ability to coordinate across plan governance stakeholders without compressing fieldwork scope.
A key tradeoff is that audit quality and documentation rigor usually come with tighter information exchange schedules from the plan sponsor. This works well when internal teams can provide participant census, contribution remittance support, and investment data on a defined cadence, but it becomes painful for groups with incomplete recordkeeper feeds.
- +Audit teams structured for multi-plan and complex data workflows
- +Fieldwork documentation supports clear auditor’s report and sign-off
- +Remediation follow-up helps translate findings into action plans
- +Engagement management keeps sponsor requests organized
- –Sponsor data turnaround deadlines can be strict during fieldwork
- –Project coordination overhead increases with multiple plan sites
- –Limited automation visibility for data mapping compared with newer tool vendors
- –Planning time is needed to align scope with audit readiness

Best for: Fits when plan sponsors need deep assurance capacity and structured audit documentation.
RSM
enterprise_vendorAudits employee benefit plans and supports retirement plan financial reporting.
Audit teams provide structured remediation planning tied to identified gaps, so follow-up actions map back to specific procedures.
RSM fits 401k audit programs that need consistent workpaper discipline and a clear trail from audit procedures to reported findings. Engagement teams typically coordinate census and contribution data inputs, then map them to required financial statements and auditor reporting outputs. Internal walkthroughs and control documentation are handled as part of the audit workflow rather than as a separate deliverable track.
A tradeoff appears when plans want highly customized automation or an internal portal for audit data exchange. In those cases, RSM’s value is strongest when clients can provide organized participant and payroll feeds and maintain timely responses during audit adjustments and management representation steps. RSM is especially useful when audit findings must translate into practical follow-up actions for eligibility testing and remittance reconciliation controls.
- +Clear audit workflow from testing workpapers to auditor reporting outputs
- +Strong coordination across participant census, contribution data, and financial statements inputs
- +Practical follow-up support for prior-year finding remediation planning
- +Engagement documentation supports client review and internal sign-off cycles
- –Limited self-serve automation for audit data exchange and validation
- –Client responsiveness can significantly affect turnaround during audit adjustments
- –Customization outside the standard engagement workflow may require additional coordination
- –Some control walkthrough depth depends on plan governance readiness

Best for: Fits when plan sponsors need disciplined ERISA audit execution and actionable follow-up for prior-year findings.
Baker Tilly
enterprise_vendorPerforms employee benefit plan audits and advises on ERISA reporting controls.
Plan-focused audit documentation workflow that ties audit evidence to Form 5500 filing-ready reporting outputs.
Baker Tilly supports 401k audits by combining ERISA audit execution with benefits-focused attest services under a CPA firm delivery model. The firm’s core work centers on plan financial statements, audit adjustments, and the auditor’s report workflow tied to Form 5500 filing output.
Teams can expect structured scoping for participation and contribution workflows, including participant census handling and remittance-related evidence. Delivery quality typically depends on tight input coordination because Baker Tilly’s audit output is constrained by the completeness and reconciliation readiness of payroll, recordkeeping, and plan-level reporting.
- +Large-firm ERISA audit delivery with standardized evidence-to-report workflows
- +Clear plan statements and Form 5500 linkage across audit documentation sets
- +Structured testing support for participant census and remittance evidence
- +Experienced auditor execution for prior-year finding follow-up cycles
- –Audit throughput depends on timely payroll and recordkeeper reconciliation materials
- –Limited public detail on automation and system-to-system data imports
- –Governance coordination load can shift to the plan sponsor during evidence requests
Best for: Fits when a plan sponsor needs a CPA-firm ERISA audit execution team with disciplined scoping and evidence management.
Sikich
specialistPerforms 401k and employee benefit plan audits with compliance and reporting support.
Audit workpapers structured around exception tracking from reconciliations into auditor reporting deliverables.
Sikich supports 401k audit engagements through ERISA-focused audit execution that maps plan sponsor data into audit evidence and reporting deliverables. Delivery centers on contribution and participant testing workflows that trace from source records through reconciliations and supporting documentation.
Sikich also handles management and auditor communications needed for audit readiness, including evidence collection coordination and documentation packaging for the independent qualified public accountant. Governance support shows up in how Sikich structures audit workpapers around controls, exceptions, and follow-up actions tied to audit outcomes.

- –Governance alignment can extend timelines if control narratives and policies lag
Best for: Fits when mid-market plan sponsors need controlled evidence mapping and dependable audit workpaper packaging.
CBIZ
enterprise_vendorOffers employee benefit plan audits for 401k, pension, and welfare plans.
Evidence-driven coordination that links participant census inputs through testing and into Form 5500 preparation dependencies.
CBIZ delivers ERISA audit and 401k plan audit services focused on delivering audit-ready financial statements and auditor’s reporting support for employee benefit plans. It fits plan sponsors that need a managed audit workflow across census, payroll and recordkeeper reconciliation, and Form 5500 inputs.
CBIZ also supports audit documentation that ties plan records to the participant population used for testing, with follow-up handling for prior-year findings when present. For organizations with multiple service relationships, CBIZ can coordinate required service organization controls evidence where the audit scope relies on outsourced processes.
- +Coordinated audit workflow across census, testing inputs, and Form 5500 support

Crowe
enterprise_vendorDelivers employee benefit plan audit and advisory services for plan sponsors.
Multi-disciplinary benefit plan execution that couples audit testing with operational remediation planning for sponsor leadership and administrators.
Crowe brings audit and advisory depth from a large public accounting firm into 401k audit engagements with ERISA plan audit delivery and related compliance support. Its services typically cover plan financial statement audit workstreams, Form 5500 preparation support, and testing workflows tied to participant and contribution records.
The differentiator versus smaller audit-only shops is multi-disciplinary coverage that often includes benefit plan and controls consultation alongside the audit execution. Crowe’s engagement model is designed to coordinate audit evidence, auditor reporting deliverables, and operational remediation planning for sponsor and plan administrator stakeholders.
- +Large-firm ERISA audit coverage with consistent execution across complex plan designs
- +Coordinates Form 5500 reporting support with evidence collection for faster close
- +Structured remediation follow-ups tied to identified audit adjustments
- +Controls-oriented walkthroughs that map testing to documented internal processes

specialistProvides employee benefit plan audits for defined contribution and other retirement plans.
Benefit plan compliance testing workflow that ties participant and remittance reconciliations to the audit lifecycle deliverables.
Withum delivers 401k audit support built around ERISA-focused plan financial statement work and annual reporting deliverables. Its engagement model typically pairs audit execution with benefit plan compliance testing workflows such as participant data validation and contribution remittance checks.
Withum also brings governance practices like documentation control and audit adjustment tracking to support reviewer continuity from fieldwork through final reporting. For teams that need a consistent audit-ready workflow across multiple plan entities, Withum’s delivery emphasis aligns with audit lifecycle management rather than only point-in-time reviews.
- +ERISA-aligned audit execution with clear linkage to plan annual reporting

Best for: Fits when plan sponsors need recurring ERISA audit execution plus reconciliation testing with controlled documentation.
Eide Bailly
specialistAudits 401k and other employee benefit plans for regional and national employers.
Staff-led audit documentation package that ties participant-level and reconciliation evidence to audit conclusions.
Eide Bailly delivers 401k audit services with an audit-workflow approach that maps evidence collection to the auditor’s report and related engagement documentation. The engagement process includes audit planning, control and process walkthrough activities, and structured execution against plan reporting requirements.
Testing is driven by plan data inputs like participant census, contribution remittance information, and reconciliation outputs that support audit conclusions. Engagement teams produce workpaper-ready results that management and plan governance groups can review during the reporting cycle.
Integration depth is largely operational through client document and data delivery rather than a published automation or API surface. Coordination requirements shift to the plan sponsor and recordkeeper data provisioning process.
- +Audit engagement process is built around ERISA-aligned evidence and documentation
- +Staff-led testing supports reconciliation and participant data validation workpapers
- +Clear audit reporting output supports management review and governance cycles
- +Project management structure fits recurring annual audit deadlines
- –Automation and API integration are not a stated focus of the audit service
- –Limited-scope configurations may not be available for every plan data environment
- –Turnaround depends on timely client delivery of census and payroll-to-recordkeeper inputs
- –Engagement staffing can increase coordination overhead for complex governance groups
Best for: Fits when a mid-market plan needs staffed ERISA audit execution and documented testing support.

How to Choose the Right 401k audit
This 401k audit buyer’s guide frames ERISA Section 103(a)(3)(C) audit execution around how plan sponsors gather evidence, validate participant and remittance inputs, and translate testing results into auditor-facing deliverables. The guide covers CLA, EisnerAmper, and EY, along with RSM, Baker Tilly, Sikich, CBIZ, Crowe, Withum, Eide Bailly, and Plante Moran.
Across the provider cards, the practical differentiators center on evidence-to-conclusion workpapers, coordinated audit project management, and the level of sponsor effort required to meet fieldwork and reconciliation deadlines. PwC, KPMG, and EY are used as reference points for enterprise audit expectations, but the guide narrows to the ten named providers for concrete buying decisions.
What a 401k audit covers and how service execution differs
A 401k audit is an ERISA plan audit engagement that tests participant and contribution processes, reconciles payroll activity to recordkeeper information, and ties plan financial statement support to an auditor’s report and workpaper conclusions. Deliverables typically include audit evidence mapped to testing steps for Form 5500 annual report support, and documented follow-up on prior-year findings.
Providers such as CLA emphasize structured workpapers that link testing evidence directly to audit conclusions and prior-year follow-up workflows. EisnerAmper emphasizes coordinated project management that sequences sponsor data requests across participant census, payroll, and investment inputs to keep documentation aligned with audit sign-off.
401k audit evaluation criteria that map to evidence, deliverables, and close
A 401k audit engagement succeeds when audit testing evidence can be traced to conclusions and then packaged into deliverables that support Form 5500 annual report inputs and auditor reporting sign-off. Providers differ most in how directly they connect testing steps to audit conclusions and how they organize evidence so auditors can close faster.
Evidence-to-conclusion workpaper linkage
CLA builds structured workpapers that connect testing steps to audit conclusions and ties engagement documentation links to prior-year follow-up workflows.
Coordinated sponsor data request sequencing
EisnerAmper runs audit project management that organizes sponsor data requests across participant, payroll, and investment inputs to keep documentation aligned with audit sign-off.
Remediation planning that maps back to procedures
RSM organizes remediation planning so follow-up actions map back to specific procedures that identified gaps, keeping prior-year findings from drifting away from the evidence record.
Form 5500 filing-ready evidence workflow
Baker Tilly ties audit evidence into plan-focused documentation workflows that produce Form 5500 filing-ready reporting outputs.
Exception tracking routed into reporting deliverables
Sikich structures audit workpapers around exception tracking from reconciliations into auditor reporting deliverables and maintains controls, exceptions, and audit adjustments in one workflow.
Documentation traceability from census to Form 5500 support
CBIZ coordinates an evidence-driven workflow that links participant census inputs through testing and into Form 5500 preparation dependencies.
How to choose a 401k audit service based on execution model and sponsor lift
The decision starts with execution model fit because some providers run highly structured evidence packages while others run heavier project coordination across multiple plan inputs. Each model affects how much sponsor time is required for data pulls, confirmations, and turnaround during audit adjustments.
Select evidence architecture by choosing the right workpaper traceability depth
If the priority is direct links from each testing step to audit conclusions with documented prior-year follow-up, CLA offers structured workpapers designed for that evidence traceability. If the priority is a clearer documentation chain that stays consistent across reconciliation and reporting deliverables, Sikich’s exception-to-reporting workflow may better match close requirements.
Match sponsor readiness to the provider’s data request sequencing workload
If sponsor teams can produce participant, payroll, and investment inputs on a tight sequence, EisnerAmper’s coordinated audit project management can reduce downstream rework. If sponsor teams prefer a more plan documentation workflow with disciplined evidence-to-report output dependencies, Baker Tilly’s Form 5500 linkage workflow fits more predictably for staffed execution.
Choose how prior-year findings should be converted into procedure-linked follow-up
If follow-up actions must map back to the exact procedures that identified gaps, RSM’s remediation planning tied to procedures supports that workflow. If follow-up needs to stay grounded in exception routing and audit adjustments during packaging, Sikich’s exception tracking structure helps keep remediation connected to evidence and deliverables.
Pick the delivery style for complex plan designs versus standardized workflows
If the plan setup is complex and needs consistent execution across complex plan designs while coordinating operational remediation planning for sponsor leadership, Crowe’s multi-disciplinary benefit plan execution is designed for that coupling. If the plan setup is less complex and the sponsor wants a structured, evidence-first ERISA audit delivery with standardized evidence-to-report workflows, Baker Tilly provides that evidence-to-report structure.
Evaluate automation visibility as a control over audit-close throughput
If audit-close throughput depends on reusable data exchange patterns, platforms with limited public automation and API detail may require manual data pulls and tight sponsor turnaround. Providers like RSM and Baker Tilly flag that audit adjustments and throughput can depend heavily on client responsiveness and timely reconciliation inputs.
Who benefits from a 401k audit service based on evidence and coordination needs
Different plan sponsors face different bottlenecks. Some sponsors struggle with mapping testing evidence into auditor-ready conclusions. Others struggle with coordinating many inputs across participants, payroll, and investment information under fieldwork timelines.
Plan sponsors that want evidence-to-conclusion traceability and documented prior-year follow-up linkage
CLA fits sponsors that need engagement documentation links that route plan testing evidence directly to audit conclusions and prior-year follow-up workflows.
Plan sponsors with multiple data streams that must be sequenced during fieldwork
EisnerAmper fits sponsors that can meet strict turnaround deadlines for participant, payroll, and investment inputs because its project management organizes sponsor data requests across those inputs.
Mid-market sponsors that need disciplined remediation tied to procedures and audit adjustments
RSM fits sponsors that require follow-up actions to map back to specific procedures and need a structured audit workflow from workpapers to auditor reporting outputs.
Sponsors focused on Form 5500 filing-ready reporting outputs driven by plan documentation sets
Baker Tilly fits sponsors that want standardized evidence-to-report workflows with clear plan statements and Form 5500 linkage across audit documentation sets.
Sponsors that need evidence packaging with exception routing from reconciliations into reporting deliverables
Sikich fits sponsors that benefit from workpapers structured around exception tracking that ties payroll and remittance reconciliations into auditor reporting deliverables.
Common 401k audit procurement mistakes that create rework during close
Many audit procurement delays come from mismatched execution models and sponsor data turnaround capacity. When sponsor data pulls and confirmations are not sequenced for fieldwork, even strong audit documentation can still miss close timelines.
Choosing a provider without verifying whether evidence-to-conclusion traceability is built into the workpapers
CLA’s structured workpapers connect testing steps to audit conclusions, while sponsors that skip this check may face manual mapping work during auditor review.
Underestimating sponsor workload created by strict fieldwork turnaround deadlines
EisnerAmper’s coordinated request sequencing can still become a bottleneck when participant, payroll, and investment confirmations miss the project cadence.
Treating remediation as a separate deliverable instead of a procedure-linked workflow
RSM maps follow-up actions back to specific procedures, while providers without that linkage can require additional evidence rework to reconcile remediation with testing.
Expecting automated audit data exchange when public integration depth is not a stated focus
RSM and Eide Bailly do not position automation and API integration as a central stated differentiator, which increases reliance on timely sponsor data availability.
Ignoring how reconciliation materials drive audit throughput and report packaging timelines
Baker Tilly and Plante Moran both tie audit throughput to payroll-to-recordkeeper reconciliation materials and document collection discipline from the sponsor.
