SOX Compliance
Definition
SOX Compliance
SOX compliance is the work a US public company does to satisfy the Sarbanes-Oxley Act’s certification and internal control requirements. Section 404 is where the cost sits, because management assesses control effectiveness and the auditor then tests that assessment.
Two assessments of the same controls, by two parties, every year.
That duplication is the design rather than an accident — management asserts, the auditor tests the assertion, and the friction is what the Act was buying.
Understanding which section drives which obligation is the fastest way to work out where effort and money actually go.
Key takeaways
- The Sarbanes-Oxley Act of 2002 applies to US public companies and their auditors.
- Section 302 requires principal executive and financial officers to certify periodic reports.
- Section 404 requires an internal control report with a management effectiveness assessment.
- Section 906 creates criminal penalties for knowing or wilful false certification.
How it works
The Act is built from a handful of sections that do distinct jobs. Section 302 requires principal executive and financial officers to certify annual and quarterly reports, confirming they reviewed them and found no material misstatements or omissions.
Section 404 is the expensive one. It requires annual reports to contain an internal control report in which management states its responsibility for internal control over financial reporting and assesses the effectiveness of that control.
Assessing effectiveness means documenting controls, testing them, and evidencing the testing. That work is continuous rather than annual — because a control tested once in December proves very little about the year.
Criminal exposure sits in the later sections. Section 906 creates criminal penalties for knowing or wilful false certifications, and section 802 makes it an offence to destroy, alter or falsify records with intent to impede a federal investigation.
Oversight of the auditors was the structural change. The Act created the Public Company Accounting Oversight Board, a nonprofit corporation established by Congress to oversee the audits of public companies in order to protect investors.
| Section | Requirement | Who it binds |
|---|---|---|
| 302 | Certify periodic reports as accurate | Principal executive and financial officers |
| 404 | Internal control report and effectiveness assessment | Management, then tested by the auditor |
| 802 | No destruction or falsification of records | Everyone |
| 906 | Criminal penalties for false certification | Certifying officers |
Section 404 dominates the budget because it is the only one requiring sustained testing. The others are obligations you meet — this one is work you perform all year.
Examples
Compliance programmes concentrate effort in a few places, and the pattern is consistent enough to predict. Every arrangement below has been tested by somebody’s auditor rather than their marketing team.
A company documents its controls once and tests them quarterly. Continuous testing is what an effectiveness assessment requires, rather than a year-end scramble.
A newly listed business discovers its control documentation does not exist. Building it becomes the dominant compliance outsourcing project of its first reporting year.
A financial controller maintains the control matrix and the testing evidence. That role carries the programme in most mid-sized companies.
A firm treats certification as a signing formality. Section 906 attaches criminal penalties to knowing false certification, which makes it something other than a formality.

- Compliance officer: the role coordinating the programme, distinct from the certifying officers.
- Compliance outsourcing: buying regulatory capability, which cannot absorb the certification duty.
- Regulated outsourcing: sector rules that layer above securities law.
- Risk outsourcing: transferring exposure, which statutory certification resists.
- Business risk: the wider category of threats, of which reporting failure is one.

FAQ
Who does SOX apply to?
United States public companies and the firms that audit them. Private companies are outside it unless preparing to list or bound by contract.
What does section 302 require?
That principal executive and financial officers certify annual and quarterly reports, confirming they reviewed them and that there are no material misstatements or omissions.
Why is section 404 the expensive part?
It requires management to assess internal control effectiveness, which means documenting and testing controls continuously, with the external auditor then testing that assessment.
What are the criminal penalties?
Section 906 creates criminal penalties for knowing or wilful false certification. Section 802 separately criminalises destroying or falsifying records to impede an investigation.
What is the PCAOB?
The Public Company Accounting Oversight Board, created by the Act as a nonprofit corporation to oversee audits of public companies and protect investors.
How often must controls be tested?
Continuously through the year. A single year-end test provides little evidence that controls operated effectively across the reporting period.
