PCAOB Audit Obligations
PCAOB audits are not optional for specific types of entities. Such audits follow PCAOB audit standards, which apply under federal law to the categories listed below:
1- Public Companies Listed on U.S. Stock Exchanges
SEC-registered firms trading on NASDAQ or NYSE are obligated to obtain PCAOB-compliant audits.
2- Companies Preparing for an IPO
Businesses planning to go public, including SPACs, are required to fulfill audit requirements for public companies—meaning a PCAOB-registered firm should be engaged.
3- Broker-Dealers Registered with the SEC
All broker-dealers should file annual reports that are subject to PCAOB audit standards, not GAAS.
4- Certain Foreign Private Issuers
If listed in the U.S., foreign issuers still must file PCAOB-audited financials, despite their non-domestic operations.
5- Subsidiaries of Public Companies
Even if the entity itself is private, if it belongs to a public parent, a PCAOB audit may be triggered in accordance with the reporting obligations.
Distinction Matters
The line drawn between PCAOB vs GAAS is not just a technical one—it is rooted in legal and investor-facing obligations. Audits under PCAOB rules include enhanced oversight on internal controls and risk procedures that standard GAAS audits do not.
When evaluating PCAOB vs US GAAP, the roles also differ. US GAAP governs how financials are prepared. On the other side, PCAOB audit standards simply determine how those financials are tested for accuracy. So, asking how is a PCAOB audit different from a normal audit becomes more than academic—it defines whether the entity is in line with regulatory expectations.
Takeaway for Growing Enterprises
If the company is in early discussions with investors or drafting SEC filings, it is vital to recognize whether PCAOB oversight applies. The audit requirements for public companies do not leave room for flexibility. Working with a firm that is not PCAOB-registered simply is not permitted.
The rules are straightforward. If the company plans to touch public capital in any form, the audit must follow PCAOB standards. No workarounds exist. It is better to know this early and prepare accordingly. For further assistance, contact Dimov Audit today.
