PCAOB audit cost is a critical budget item for public companies and businesses preparing for an IPO. Yet there is no universal flat fee for a PCAOB audit: the price depends on the financial statements to be audited, operating complexity, audit risk, internal controls, reporting deadlines, and the resources required by the engagement team. A smaller issuer with complex accounting can incur substantial fees, while another company of similar size may have a simpler engagement.
For CFOs and audit committees evaluating proposals, the useful question is not simply “What is the cheapest audit?” It is “What scope is required, what work is included, which risks may trigger additional fees, and can the firm deliver a high-quality independent audit on the necessary timetable?” This guide explains publicly disclosed fee benchmarks, common cost drivers, IPO-specific considerations, and a practical approach to requesting comparable quotes.
How Much Does a PCAOB Audit Cost?
Published fees vary widely. PCAOB audits of U.S. SEC issuers are subject to PCAOB standards and relevant SEC independence rules; firms price them according to their actual engagement requirements. Published historical industry medians provide context, not a quote for a particular issuer.
Historical public company audit fee benchmarks
A PCAOB economic analysis citing Audit Analytics data reported the following median audit fees for fiscal years 2020 and 2021. These figures are historical, segmented by filer classification, and should not be represented as current 2026 price quotes.
Issuer filer group | FY 2020 median | FY 2021 median |
Non-accelerated filers | $258,884 | $240,000 |
Accelerated filers | $940,000 | $852,004 |
Large accelerated filers | $2,645,000 | $2,447,000 |
The variation illustrates why “average PCAOB audit fees by company size” can be misleading. The medians reflect different populations, business complexity, and reporting obligations. They do not establish a minimum, maximum, or standard fee for micro-cap or IPO engagements.

What is included in public company audit fees?
An annual audit fee proposal may cover planning, risk assessment, year-end financial statement audit procedures, required communications, audit reporting, and sometimes interim reviews or regulatory filing-related services. What a firm includes in its quoted “audit fee” can differ from the SEC fee-disclosure category or from another firm’s proposal. Always request an itemized scope.
Why PCAOB Audit Costs Vary: Seven Major Fee Drivers
1. Company size, subsidiaries, and geography
More entities, locations, currencies, and consolidations can increase planning and testing. Cross-border audits may involve component auditors, coordination across jurisdictions, and additional documentation.
2. Industry and accounting complexity
Revenue contracts, fair-value measurements, warrants, stock compensation, business combinations, and digital-asset exposure can require specialized audit skills. The number of complex transactions can matter more than revenue alone.
3. Quality of accounting records and PBC readiness
Timely reconciliations, a complete trial balance, account schedules, contracts, and an organized prepared-by-client (PBC) portal make the audit process more efficient. Incomplete records often cause repeat requests, rework, and timeline pressure. Management must still prepare the underlying information; the auditor must obtain independent evidence.
4. Internal controls and SOX 404(b)
An audit of internal control over financial reporting (ICFR) may be required for certain issuers under Section 404(b) of the Sarbanes-Oxley Act. Not every public company is subject to this auditor-attestation requirement. Where required, an integrated audit generally adds control testing and reporting work. Material weaknesses can affect audit procedures and remediation planning.
5. First-year or successor auditor work
A first-year engagement can require additional attention to opening balances, accounting policies, prior-period matters, systems, and audit transitions. Companies should discuss predecessor auditor access and transition logistics early.
6. Audit deadlines and filing timetables
Accelerated reporting dates, IPO filing milestones, and last-minute changes can require additional resources. An organized timetable with agreed milestones reduces surprises but does not eliminate the need for sufficient audit evidence.
7. Engagement quality, staffing, and specialist input
Partner oversight, experienced managers, valuation specialists, IT specialists, and engagement quality reviews may be needed based on the risks and standards that apply. Proposals should describe the actual team—not only the name of the firm.
Public Company Audit Fees: What SEC Disclosures Can Tell You
Many issuers disclose principal accountant fees in proxy statements or annual-report disclosures, commonly for the two most recent fiscal years. Item 9(e) of Schedule 14A distinguishes audit fees, audit-related fees, tax fees, and all other fees. These categories can help an audit committee research comparable issuers, but care is needed before treating a disclosed aggregate as the cost of one stand-alone financial statement audit.
Disclosure category | Typical interpretation |
Audit Fees | Annual financial statement audit, quarterly financial statement reviews, and specified normal regulatory filing-related work |
Audit-Related Fees | Other assurance and related services reasonably connected with audit/review work |
Tax Fees | Qualifying tax compliance, advice, and planning services |
All Other Fees | Other permissible products and services outside the preceding categories |
Compare companies in a similar industry, reporting classification, scale, and complexity. Read the narrative descriptions and identify acquisitions, restatements, first-year engagements, and other events that make one year atypical. An audited financial statement fee disclosure is not the same as a market quote for your organization.

IPO Audit Cost: What Should an IPO Candidate Budget?
IPO candidates may require audits of multiple historical financial statement periods, interim financial statement reviews, and procedures connected with a registration statement. An IPO-related audit budget should be built around the specific transaction and issuer eligibility rather than assuming that the annual public-company audit fee will cover everything.
Potential IPO audit cost components
Historical financial statement audits for required periods, including any additional PCAOB procedures needed for previously audited periods.
Quarterly/interim reviews and comfort-letter work when applicable to the transaction.
Accounting complexity involving equity instruments, revenue recognition, acquisitions, and consolidation.
Required auditor consent and filing-related work; confirm whether these are included or separately scoped.
The first annual public company audit after listing, plus any applicable ICFR work as reporting status changes.
An SEC registration does not automatically make all accounting preparation or SOX implementation an allowable auditor-provided service. Independence limits must be respected when selecting separate accounting, control-remediation, legal, and audit advisers.

Do not use a single generic “IPO audit cost” figure as a promise or a reliable budget. A proposal based on trial balances, reporting periods, entity structure, risk areas, and a target filing date will be more meaningful.
Small-Cap vs. Mid-Tier vs. Big Four PCAOB Audit Cost
The Big Four and smaller or mid-tier registered accounting firms can differ in staffing models, global networks, industry coverage, partner access, and fees. However, firm category is not a substitute for verifying PCAOB registration, independence, engagement team experience, inspection history, and fit with the issuer.
Decision factor | What to evaluate |
Pricing | Compare total scoped fee and potential additional charges |
Industry experience | Relevant issuer audit engagements and complex accounting experience |
Resourcing | Partner/manager involvement, specialists, capacity during filing window |
International operations | Component auditor coordination and relevant jurisdiction experience |
Regulatory readiness | PCAOB registration, independence, inspection history |
Continuity | Team retention and realistic engagement milestones |
For micro-cap companies seeking an affordable PCAOB auditor, “affordable” should mean appropriate scope and predictable engagement economics—not reduced audit evidence or noncompliance. A suspiciously low quote can indicate omitted services, unrealistic assumptions, or misunderstandings about the engagement.

Weights are illustrative. Audit committees should adapt them to the issuer and document the basis for their choice. Selection and oversight responsibilities cannot be reduced to a lowest-bid calculation.
How to Reduce Avoidable Audit Costs Without Reducing Audit Quality
Complete account reconciliations and resolve material differences before fieldwork.
Prepare a PBC list with a named owner, due date, source system, and review status.
Address complex transactions promptly, preserving executed agreements and technical accounting memos.
Maintain an accurate entity listing, consolidation schedules, and evidence of key management reviews.
Identify IT system changes, access issues, and control deficiencies early.
Agree on a clear escalation path and decision log for audit requests and proposed adjustments.
Cost efficiency comes from better preparation and fewer avoidable interruptions—not from limiting necessary procedures or directing the auditor toward a preferred conclusion.
PCAOB Audit Cost FAQs
What is the average PCAOB audit fee for a small public company?
There is no current universal rate. Historical PCAOB analysis reported median non-accelerated filer audit fees of about $259,000 for 2020 and $240,000 for 2021, but those are not quotes for today or benchmarks for every micro-cap issuer. Actual fee proposals depend on risk, scope, and reporting needs.
Are PCAOB registration fees the same as audit fees?
No. PCAOB registration and annual fees are paid by registered accounting firms under PCAOB rules; they are not the same as the professional fees charged to an issuer for an audit.
Does an IPO require more than one year of audited financial statements?
Frequently, yes, but the number of audited periods depends on the issuer, registration form, eligibility for accommodations, and specific SEC requirements. Confirm the financial statement periods with the company’s securities counsel and audit firm.
Is a PCAOB audit cheaper with a mid-tier firm than with a Big Four firm?
Sometimes, but not invariably. Compare scope, industry experience, staffing, specialist needs, and assumptions before drawing conclusions from the brand or size of the auditor.
Can public companies obtain fixed-fee PCAOB audits?
A firm may propose fixed or capped elements subject to defined assumptions. Companies should examine change-order triggers and unusual transaction provisions rather than relying on the headline price alone.
Who approves public company audit fees?
Applicable audit committee requirements place responsibility for the independent auditor’s appointment, compensation, and oversight with the audit committee. The precise process depends on the issuer and governing rules.
Do audit fees include SOX 404(b) testing?
Only if the engagement scope and applicable obligations call for it. Section 404(b) does not apply to every issuer; ask the prospective firm to document its assumed ICFR scope.
Where can I find SEC audit fees for comparable companies?
Review the principal accountant fee disclosures in relevant issuers’ proxy statements or annual reports, then assess differences in accounting complexity and the included services.
