Direct answer: when a CPA belongs in the correction team
A ROBS correction needs a CPA when the facts must tie to accounting records: bank activity, payroll, W-2 and Form 941 data, C corporation income-tax returns, tax basis, shareholder records, Form 1120 support, Form 5500 schedules, Form 5330 screening, amended-return packages, or examination document production. IRS ROBS materials specifically flag Form 5500, Form 1120, participant information, rollovers, stock valuation, employer securities and recordkeeping as recurring review areas.[S1][S2][S4][S5][S6] If you are still sorting the fact pattern, start with the ROBS compliance case studies before scoping CPA work.
The CPA lane is important but bounded. A CPA can calculate, reconcile, document assumptions, prepare or amend tax filings within scope, and represent before the IRS when properly authorized. A CPA cannot give ERISA legal opinions merely by being a CPA, determine plan eligibility, guarantee IRS or DOL acceptance, substitute for an independent valuation, audit, TPA or fiduciary, create privilege automatically, or erase conflicts.[S3][S7][S8][S9][S13][S14][S15][S16]
Trigger and triage before hiring
Start with the correction trigger: missing Form 5500, payroll mismatch, participant eligibility error, stock-valuation gap, owner personal-expense issue, prohibited-transaction concern, Form 1120 inconsistency, Form 5330 question, IRS contact or DOL EBSA inquiry. Preserve records before rebuilding them. Do not backdate, overwrite or replace source files. Make a triage sheet that lists the agency, years, entities, plan number, requested records, response deadlines, affected participants, likely forms and open legal questions.
CPA versus ERISA counsel, EA, TPA, auditor, appraiser and fiduciary
Use a responsibility matrix so one professional is not silently asked to cover every lane. Circular 230 recognizes CPAs, attorneys, enrolled agents and enrolled retirement plan agents for IRS practice within defined rules, but credentials do not merge accounting, legal, valuation, plan-administration and fiduciary roles.[S7][S8][S9]
A ROBS owner should expect the CPA to coordinate with ERISA counsel rather than replace counsel. Prohibited-transaction provisions and fiduciary duties are legal standards; the CPA may calculate amounts and prepare supporting schedules, but counsel frames the legal conclusion and correction position.[S13][S14]
Credential, license, discipline and directory checks
Verify the CPA through the state board of accountancy or official state licensing lookup for the jurisdiction where the CPA is licensed. Confirm active status, firm license where relevant, attest authority if the work includes an audit or review, and any public discipline. The IRS tax-professional page explains that paid preparers have different credentials and that the IRS directory can identify preparers with credentials or select qualifications. The directory is a credential tool, not a ROBS recommendation, ranking or endorsement.[S10]
Ask for experience with employee benefit plans, closely held C corporations, payroll reconstruction, Form 1120, Form 5330, Form 5500 data coordination, IRS examination production and counsel-directed correction work. If the CPA will sign returns, confirm PTIN use and who reviews positions. If the CPA will represent the taxpayer, confirm Form 2848 authority. If the CPA only needs records, Form 8821 may be enough.[S7][S8][S9]
Engagement scope, deliverables and conflicts
The engagement letter should identify the client, covered entities, plan years, tax years, specific forms, deliverables, source documents, assumptions, management responsibilities, representation authority, billing structure, retainer treatment, billing increments, fixed-fee exclusions, change-order rules, file-delivery rights and termination rights. Ask whether the CPA is advising, preparing, compiling, reviewing, auditing or only consulting. Those labels affect independence, responsibility and deliverables.
Attest independence is different from advisory or tax conflicts. For an attest client, a CPA who performs management functions, makes correction decisions, prepares source documents, takes custody of assets, designs controls, or accepts responsibility for the subject matter may impair independence under AICPA nonattest-service standards. Those standards require client management to oversee the nonattest service, evaluate results and accept responsibility; state-board and firm rules may be stricter.[S15]
Representation authority and filing lanes
Form 2848 authorizes an eligible individual to represent a taxpayer before the IRS and receive confidential tax information. Form 8821 authorizes designated people or organizations to inspect or receive confidential information for listed tax matters, but it does not authorize representation. Match the authorization to the corporation, owner, plan sponsor, excise-tax filer, payroll-tax matter or other taxpayer before the CPA speaks for anyone.[S8][S9]
Separate the lanes before amending anything. Payroll work may affect W-2 and Form 941 support. Corporate work may affect Form 1120 and tax basis. Plan reporting may affect Form 5500 and EFAST2 data. Prohibited-transaction screening may point to Form 5330, but a screen is not liability. Correction program filings may have agency deadlines. The safest sequence is facts, legal lane, calculation package, draft filings, counsel or responsible-party review, then filed amendments if required.[S3][S4][S5][S6][S11][S12][S14]
Records, reconstruction and CPA workpapers
Give the CPA source records, not just summaries: bank statements, credit-card statements, payroll registers, W-2 and 941 support, Form 1120 and depreciation schedules, Form 5500 filings, trial balances, general ledgers, participant census, contribution records, plan allocations, rollover records, stock ledger, cap table, valuation reports, invoices, receipts, board approvals, owner reimbursement records, loan documents, leases, family payroll support and provider communications.
The workpapers should show source assumptions, dates, reconciliation bridges, excluded items, duplicate removal, unresolved gaps, preparer signoff and a tie-out from source records to any form or schedule. For employer stock valuation, the CPA can supply financial statements, capitalization data and transaction history. The independent appraiser, not the CPA by default, should own the value conclusion when an independent valuation is required.[S1][S2][S16]
Participant-account and lost-earnings work needs particular care. The CPA may check payroll and bank math, while the TPA or recordkeeper applies plan terms and allocation rules, and counsel determines the correction method if legal interpretation is needed. Do not double count a missed contribution as both unpaid payroll and lost earnings without showing the principal, earnings input and correction program logic separately.

These five examples are original arithmetic checks with dates, assumptions, formulas, results and limits. They are not market quotes, agency predictions, legal conclusions or individualized tax advice.
Privilege, second opinions and red flags
CPA work does not automatically create attorney-client privilege. Ordinary bookkeeping, tax preparation and return advice may remain outside privilege even if counsel is copied. Counsel-directed accountant involvement may support legal advice in some circumstances, but the Kovel-style caveat is that protection is fact-specific and jurisdiction-specific. Keep legal analysis, accounting schedules, valuation inputs and filed-return workpapers separated and labeled.
Consider a second opinion or changing CPAs if the CPA refuses to provide workpapers, cannot explain assumptions, gives ERISA legal opinions outside competence, promises agency acceptance, dismisses state-board or IRS discipline checks, ignores conflicts, pressures you to sign incomplete filings, or cannot distinguish advisory, tax, attest, valuation and representation roles. Preserve deadlines and transfer the source file, production index and open-issue list before changing professionals.[S7][S10][S15]
