How Much Does a PCAOB Audit Cost for an OTC Company?
There is no single price for a PCAOB audit. This guide explains what actually moves the fee, what a fixed-fee proposal should include, and how to benchmark what comparable companies pay using their own SEC filings.
"How much will the audit cost?" is usually the first question an OTC company CFO asks a prospective auditor, and the honest answer is that it depends on the company. Two issuers with similar revenue can receive very different quotes because the work required under PCAOB standards is driven by risk and complexity, not by size alone.
This article does not quote market prices, because published "average fee" figures are rarely comparable to a specific engagement. Instead, it explains what drives the fee, what a fixed-fee proposal should and should not include, which costs sit outside the audit, and how you can benchmark your quote against the fees your peers have publicly disclosed to the SEC.
What drives the cost of a PCAOB audit
Audit effort is a function of how much evidence the auditor needs to gather to support an opinion. The following factors move that effort most for OTC Markets companies.
Business and structural complexity
- Number of entities and countries. Each subsidiary, especially one in another jurisdiction, can add consolidation work, foreign currency translation, local statutory considerations and, in some cases, the involvement of another audit firm.
- Revenue streams. A single product sold on standard terms is far simpler to test than multiple contract types with bundled deliverables, variable consideration or principal-versus-agent questions under ASC 606.
- Complex accounting areas. Leases (ASC 842), share-based payments and warrants (ASC 718, and liability-versus-equity classification), business combinations and purchase price allocations (ASC 805), convertible debt and derivatives, and impairment analyses all require specialized procedures and often valuation specialists.
- Digital assets. Crypto holdings raise existence, rights-and-obligations and fair value questions, and may require testing of custody arrangements and blockchain data.
Risk factors
- Going concern. Many OTC issuers have recurring losses. Evaluating management's plans and the related disclosures (see going concern) adds procedures and partner time.
- Related-party transactions, reverse mergers and shell history. These carry elevated fraud and disclosure risk and require additional inquiry and corroboration.
- Prior restatements or material weaknesses. Known control problems reduce the auditor's ability to rely on the company's processes, which increases substantive testing.
Readiness of the company
- Quality of the close process. Reconciled accounts, a clean trial balance, supported journal entries and a timely client-prepared schedule list are the single biggest lever a company controls. Late or incomplete deliverables translate directly into extra hours.
- First-year audits. A new auditor must obtain evidence over opening balances, learn the business and, under PCAOB AS 2610, communicate with the predecessor auditor. If prior periods cannot be relied on, or the predecessor cannot reissue its report, a reaudit of those periods may be needed. That is a one-time but significant cost; see our guide on how to change auditors.
Work beyond the annual audit that belongs in the budget
The annual audit opinion is only part of the recurring assurance cost for an SEC-reporting company.
- Three quarterly reviews. Rule 10-01(d) of Regulation S-X requires interim financial statements included in Form 10-Q to be reviewed by an independent public accountant before filing. Budget for three reviews per year; see our Form 10-Q review service.
- Internal control over financial reporting. Management must assess ICFR every year. Under Section 404(c) of the Sarbanes-Oxley Act, companies that are neither accelerated nor large accelerated filers are exempt from the auditor attestation requirement, but the auditor still obtains an understanding of internal control as part of the audit, and a company that becomes an accelerated filer (and is not an emerging growth company) faces an integrated audit under AS 2201. See SOX 404 and ICFR.
- SEC comment letters. Responding to SEC staff comments on your financial statements often requires auditor involvement that is not part of the base scope.
- Consents and registration statements. If your audited financial statements are included or incorporated in a Form S-1 or S-8, the auditor must provide a written consent, which typically involves updated subsequent-events procedures. Offerings with tight timetables may also require comfort letters.
- Timing and rush work. The Form 10-K is due 90 days after fiscal year-end for non-accelerated filers (75 days for accelerated filers). Compressing fieldwork into the last weeks before that deadline, or catching up on delinquent filings, typically costs more than a planned timetable.
What a fixed fee should include, and what it usually does not
A fixed fee is only as useful as the scope written behind it. When comparing proposals, confirm each of the following in writing.
| Usually inside a fixed audit fee | Usually outside, or priced separately |
|---|---|
| Annual audit of the consolidated financial statements under PCAOB standards | Reaudits of prior periods |
| Quarterly reviews, if expressly listed | Consents and comfort letters for new registration statements |
| Required communications with the audit committee or board | Responses to SEC comment letters |
| Form AP filing by the audit firm | Significant unusual transactions arising mid-year (acquisitions, reverse mergers, complex financings) |
| Procedures on the entities and accounting areas listed in the proposal | Additional work caused by late, incomplete or restated client schedules |
Ask the firm to state the assumptions behind the price: number of entities, expected account balances, reliance on specialists, the client deliverables list and dates, and how change orders are approved. SESGLO agrees the fixed fee in writing before fieldwork, together with a written scope and a week-by-week timeline; our pricing approach explains how we set it.
How SESGLO quotes: we do not publish fee ranges. We meet with you first to evaluate your company, then present a formal written proposal with a fixed fee. Schedule a meeting or see how we price.
Costs of being public that are not audit fees
When budgeting for SEC reporting, separate the audit fee from the other recurring costs that often get attributed to "the audit".
- EDGAR filing agent and Inline XBRL tagging. Rule 405 of Regulation S-T requires financial statements in periodic reports to be tagged in Inline XBRL. Most OTC companies pay a filing agent or software vendor for EDGARization and XBRL.
- OTC Markets fees. OTCQX and OTCQB companies pay application and annual fees to OTC Markets Group. The OTCQB Rules state that all OTCQB fees are published in the OTC Markets Corporate Services Fee Schedule, which may change from time to time; check it directly rather than relying on older figures.
- Securities counsel. Drafting the 10-K and 10-Q narrative, 8-K reports, proxy materials and any registration statements is legal work, not audit work.
- Accounting support. Technical accounting memos, valuation reports and outsourced controllership are management's responsibility. Your auditor cannot prepare them without impairing independence under SEC Rule 2-01 of Regulation S-X and PCAOB independence rules.
- Transfer agent, investor relations and D&O insurance. These are ordinary costs of a public company and should be budgeted separately.
How to benchmark audit fees using peers' SEC filings
You do not need a paid survey to see what comparable companies pay. SEC-reporting companies must publicly disclose the fees billed by their principal accountant.
Where the disclosure lives
Item 14 of Form 10-K, "Principal Accountant Fees and Services", requires the information called for by Item 9(e) of Schedule 14A. That item requires disclosure, for each of the last two fiscal years, of:
- Audit Fees: the annual audit, the reviews of Form 10-Q financial statements, and services normally provided in connection with statutory and regulatory filings.
- Audit-Related Fees: assurance and related services reasonably related to the audit or review, with a description.
- Tax Fees: tax compliance, advice and planning by the principal accountant, with a description.
- All Other Fees: any other products and services, with a description.
- The audit committee's pre-approval policies and the percentage of services approved under them.
Under General Instruction G(3) of Form 10-K, Part III information (including Item 14) may be incorporated by reference from a definitive proxy or information statement filed within 120 days after fiscal year-end. So if the 10-K says the information is "incorporated by reference", look in the company's DEF 14A or DEF 14C instead.
A practical search routine
- Build a peer list of 10 to 20 SEC-reporting OTC companies similar to yours in industry, revenue, number of subsidiaries and geographic footprint.
- Open EDGAR full-text search, enter the phrase "Principal Accountant Fees and Services" in quotes, add the company name or CIK, and filter by form type (10-K, DEF 14A).
- Record the Audit Fees line for both years shown, the auditor's name, and whether the company changed auditors (a change can make one year a first-year audit).
- Normalize before comparing. Note fiscal year, number of entities, whether the company had an acquisition, going concern language or a restatement, and whether the fee includes ICFR attestation.
- Read "Audit-Related" and "All Other" descriptions. Registration statement consents and comfort letters often appear there and explain year-to-year swings.
Note: Disclosed amounts are fees billed for the period, not the fee agreed for a future engagement. Treat them as a reasonableness check, not a price list.
Why choosing on price alone is risky
An audit that does not hold up to PCAOB inspection or SEC scrutiny can cost far more than the fee saved: reaudits, amended filings, delayed 10-K filings and, for OTCQB companies, questions about continued eligibility. The OTCQB Rules require audits to be performed by a PCAOB-registered auditor and the audit opinion not to be adverse, disclaimed or qualified.
Before engaging any firm, do three things:
- Read its PCAOB inspection reports. The PCAOB publishes the public portion of every firm inspection report. Under Section 104 of the Sarbanes-Oxley Act, firms that regularly audit 100 or fewer issuers are inspected at least once every three years, and quality control criticisms become public if not addressed to the Board's satisfaction within 12 months.
- Check Form AP history. Registered firms file Form AP for each issuer audit report, disclosing the engagement partner and other participating firms. The PCAOB's AuditorSearch lets you look up a firm's issuer audits and engagement partners.
- Meet the engagement partner. Ask how much of the work the partner performs personally, who else participates, and where the work is done.
