What Makes Q2 2026 Different
Q2 2026 is half-over — but in SOX terms, it's a deadline minefield. The Q1 10-Q filed in May was just the warm-up. The real pressure builds through June and into the August 10-Q window. If you are an accelerated or large accelerated filer, you already know the clock is ticking on Section 302 certifications, ITGC testing cycles, and the external auditor's review of your internal controls.
This post covers the filing dates that matter, the PCAOB updates that changed what auditors are looking for, and the compliance checklist you need before your next SOX deadline.
10-Q Filing Dates: Q2 2026 by Filer Type
The 10-Q filing deadline is measured from your fiscal quarter end, not the calendar quarter. The table below uses a standard December 31 fiscal year-end.
| Filer Category | Public Float Threshold | Q2 10-Q Deadline | Notes |
|---|---|---|---|
| Large Accelerated Filer | > $700M | August 14, 2026 | 40 days post-quarter-end. 404(b) external auditor attestation required. |
| Accelerated Filer | $75M – $700M | August 19, 2026 | 45 days post-quarter-end. Management ICFR assessment only. |
| Non-Accelerated Filer | < $75M | August 19, 2026 | 45 days post-quarter-end. Smaller reporting company (SRC) scaled disclosures may apply. |
| Smaller Reporting Company (SRC) | < $250M | November 14, 2026 | Confirm eligibility with counsel. Scaled reporting available if qualified. |
Important: The Q2 10-Q filing (April–June 2026) is due in August, not June. The June 30 date is the proxy statement deadline, not a quarterly report deadline.
Key Date — June 30, 2026: DEF 14A Proxy Statement & Q1 10-Q Wrap
Calendar-year companies must file their proxy statement by June 30. SOX touchpoints include: CEO/CFO Section 302 certification of Q1 results, audit committee report updates, ICFR status disclosure, and any material weakness disclosures from Q1 testing.
PCAOB Updates You Need to Know for 2026
Three PCAOB developments are reshaping how deficiencies get classified and communicated in 2026.
AS 1000 (Overall Responsibilities of the Auditor)
AS 1000 is now fully embedded in audit engagements. It clarifies the auditor's responsibility to form an opinion on the financial statements while also explicitly addressing ICFR. For companies undergoing 404(b) attestation, this means your external auditor is applying a more rigorous internal control testing scope than the pre-AS 1000 standard.
Revised Deficiency Taxonomy
The PCAOB updated its internal control deficiency classification to use a severity gradient: control deficiency, significant deficiency, and material weakness. The intermediate significant deficiency tier means deficiencies that historically might have been managed internally are now formally communicated to audit committees.
Action: Request a briefing from your external auditor on how the updated deficiency taxonomy applies to your current testing scope. Understand the framework now so you can prioritize remediation before year-end.
Quality Indicators (QIs)
The PCAOB's quality indicator framework requires firms to track and report internal metrics. Audit committees should expect their auditor to provide a QI overview as part of annual communications.
Q2 2026 SOX Compliance Checklist
Use this checklist now — before June 30. Every item below has a hard deadline or a downstream consequence if missed.
Before June 30 (Proxy Statement Filing)
- Confirm Q1 10-Q filed on time. May 15 (large accelerated) or May 20 (accelerated/non-accelerated). Pull the filing from EDGAR and confirm all exhibits, including Section 302 certifications, are attached.
- Complete Q2 ICFR testing for key controls. Focus on: revenue recognition, account reconciliations, journal entry approval workflows, and IT general controls. Document testing results and exception log before June 30.
- Review prior material weakness remediation status. Document remediation steps, evidence collected, and testing results confirming closure. Include in the DEF 14A ICFR disclosure.
- Brief the audit committee on ICFR status. Schedule a Q2 audit committee meeting before June 30. Topics: Q1 certification outcomes, Q2 testing status, deficiencies identified, and remediation plan.
- Reconcile clawback policy compliance. Per SEC Rule 10D-1, companies must have a clawback policy and disclose its terms. Confirm the policy is documented, triggering events are defined, and the policy has been applied to any applicable restatements.
- Review Section 906 certification process. CEO/CFO certifications under Section 906 carry criminal penalties for false filings. Confirm sign-off timing with legal counsel.
By August 14/19 (Q2 10-Q Filing)
- Draft Q2 10-Q MD&A section. Management's Discussion and Analysis must cover known uncertainties, events, and trends. This section faces the most SEC comment risk.
- Collect and review subsequent events. Any events between June 30 and the filing date that materially affect financial statements must be disclosed.
- Confirm 404(b) auditor attestation scope. Large accelerated filers: confirm testing scope, additional procedures, and sign-off timeline with your engagement partner.
- Update disclosure controls and procedures certifications. Section 302 certifications cover DC&P effectiveness. Ensure updated process documentation is ready for CEO/CFO sign-off within 15 days of quarter-end.
- Review PCAOB inspection findings if applicable. If your external auditor was inspected in 2024 or 2025, review the report for findings that could affect your audit scope.
Don't Wait for the Audit Committee Meeting
The most common SOX compliance failure in Q2: companies that wait for the scheduled audit committee meeting to escalate control issues. By the time the committee meets, the window for remediation may have closed.
Engage your external auditors early. If there is a control gap, find out now, not the week before filing. Give yourself time to remediate, document it, and present a clean picture to the audit committee.
