SOX 302 vs. 404: What Management Needs to Understand

May 8

Written By Nerik .

When executives certify their company’s financial statements, they’re relying on two distinct sections of the Sarbanes-Oxley Act — Section 302 and Section 404. These sections are related but not the same, and confusing them creates real compliance risk. Here’s what management needs to understand about each one.

SOX Section 302: Quarterly CEO and CFO Certifications

Section 302 requires the CEO and CFO of every public company to personally certify, on a quarterly basis, that the financial statements fairly present the company’s financial condition, that disclosure controls are effective, and that any significant deficiencies, material weaknesses, or fraud involving ICFR have been disclosed to the audit committee and external auditors.

Section 302 applies to every public company every quarter, regardless of size or filer category. It is a personal certification — meaning the signing officers face criminal liability if statements turn out to be materially false.

SOX Section 404: Annual Assessment of Internal Controls

Section 404 goes deeper. Rather than a quarterly certification of outcomes, it requires management to assess and report on the design and operating effectiveness of internal control over financial reporting (ICFR) at year-end. This assessment must be included in the company’s annual report (Form 10-K).

Section 404 has two parts. Under 404(a), management — typically the CEO and CFO — must evaluate ICFR effectiveness and disclose any material weaknesses. Under 404(b), companies that qualify as accelerated or large accelerated filers must also obtain an independent attestation on ICFR from their external auditor. Smaller reporting companies and non-accelerated filers are subject only to 404(a).

Unlike 302, Section 404 is an annual exercise that requires a structured, documented assessment — usually built around a framework like COSO — covering entity-level controls, IT general controls, and process-level controls across financially significant areas.

Key Differences Between 302 and 404

Frequency: Section 302 certifications happen every quarter with each 10-Q and 10-K filing. Section 404 assessments happen once per year, in connection with the annual report.

Scope: Section 302 covers disclosure controls broadly — any information that should be included in SEC filings. Section 404 is specifically focused on internal control over financial reporting.

Depth: Section 302 is a certification — the officers attest to what they know. Section 404 requires a full assessment with documented evidence, testing, and management’s explicit conclusion on effectiveness.

External auditor involvement: Section 302 does not require external auditor attestation. Section 404(b) does — for accelerated and large accelerated filers, the auditor independently assesses and opines on ICFR.

Applicability: Section 302 applies to all public companies, regardless of size. Section 404(b) applies only to accelerated and large accelerated filers.

How 302 and 404 Work Together

The two sections are complementary. A well-functioning Section 404 program — with tested, documented controls and clear remediation processes — gives the CEO and CFO the evidence base they need to make their Section 302 certifications with confidence.

Conversely, a weak 404 program creates real risk for the 302 certification. If a material weakness exists and management was not aware of it, the 302 certification could be challenged. This is why companies that are serious about SOX compliance treat the 404 program as infrastructure — not just a compliance exercise.
