To ensure your company remains compliant with the Sarbanes-Oxley Act (SOX), it’s essential to understand the specific rules governing data retention. What records must be preserved, and for how long? Which data types require secure storage, and what are the best practices for maintaining compliance? This guide will break down SOX data retention requirements, helping you implement policies safeguarding your organization’s financial integrity and legal standing.

Sarbanes-Oxley and Record Retention Compliance Mandates

SEC Regulations

According to SOX, the SEC must establish rules on data retention. Strict data retention practices serve the goal of the SOX Act to prevent corporate fraud and ensure transparency in financial reporting. Therefore, companies must avoid destroying the records required for future regulatory investigations.

Record retention is one of the key compliance focuses. The rules are designed to prevent document destruction and ensure accountability in financial reporting.

SEC Rule 2-06 of Regulation S-X (17 CFR 210.2-06)

According to SEC’s data retention rules, accounting firms must store records for 7 years. The scope of data retention includes work papers and documents containing conclusions related to financial audits and reviews, such as emails, notes, and memos.

• Workpapers – These documents show an accountant’s steps, the evidence they collected, and the conclusions they reached during an audit or review.
• Audit Records – Any notes, emails, reports, or other documents (including digital files) related to an audit. This includes records that support the auditor’s conclusions and any that show different or conflicting information about critical issues.

SOX and SEC Rule 17a-4

SOX and SEC Rule 17a-4 establish data retention requirements for broker-dealers, security-based swap dealers (SBSDs), and major security-based swap participants (MSBSPs).

SOX mandates financial records retention for at least 7 years, tamper-proof data storage and executive accountability. Companies must also maintain detailed audit trails for modifications or keep data in write-once-read-many (WORM) formats, preventing edits or deletions. SEC Rule 17a-4, updated in 2022, requires firms to keep certain records for 3 to 6 years and ensure data accessibility for the first 2 years. Firms must also provide regulators with prompt electronic access to records through a third-party provider or a certified executive officer.

SEC Rules Under Exchange Act Section 13

SEC also sets requirements for corporate recordkeeping. They are:

• Data retention period – At least 5 years, with specific data types requiring extended retention periods. For the first two years, data needs to be easily accessible.
• Data availability – Records must be easily retrievable for SEC inspections and audits, including audit logs with modifications or deletions. Besides that, companies need to implement internal controls that would help ensure that data is safe from tampering or destruction, it can only be accessed by authorized people,
• Data formats – Companies must store data that prevents unauthorized alterations or deletions, such as a WORM (Write Once, Read Many) format or tamper-proof storage methods.
• Data types – Companies must keep financial reports, audit records, policies, and documents relevant to SOX internal controls, data governance, and financial disclosures. This includes data that supports filings with the SEC, such as Forms 10-K, 10-Q, and 8-K.

CEO and CFO Responsibilities Under SOX

CFO and CEO are responsible for ensuring the effectiveness of internal controls and overseeing the creation and certification of financial statements.

CEOs and CFOs must personally certify that financial statements are:

1. Accurate and free from material misstatements.
2. Complete, including all financial activities and transactions.
3. In compliance with SEC regulations, including meeting SOX retention requirements.

If serious errors or fraud are discovered in the financial reporting process, the company will face severe penalties for noncompliance.

Record Retention Best Practices for SOX Compliance

Summing up all requirements, here is the list of best practices to ensure that your company has implemented strong record retention policies:

• Establish a clear retention policy. The policy must define which records must be retained and for how long. Define roles responsible for monitoring retention policies.
• Establish a whistleblower policy. SOX-compliant companies need to encourage reporting of compliance violations.
• Implement mechanisms for automatic retention. Automated solutions allow you to define a data retention schedule that could help prevent accidental deletion or premature disposal.
• Choose a data storage solution that prevents unauthorized changes or deletions. Critical data could be stored in WORM (Write Once, Read Many) or other tamper-proof formats.
• Maintain secure data backup processes. Ensure backups are encrypted, protected from unauthorized access, and tested periodically to verify data integrity and recovery capabilities.
• Keep records readily accessible. SOX requires data to be accessible for at least two years for quick audit retrieval. Ensure authorized personnel can retrieve records efficiently and securely when needed.
• Implement record management systems. Consider those that enable indexing, tagging, and full-text search capabilities.
• Enable audit logging. It is necessary to track who accessed, modified, or deleted records.
• Enforce role-based access controls (RBAC). That would help limit data access to authorized employees.
• Run user access review. Regularly review and update permissions to prevent unauthorized changes.
• Conduct regular training sessions. Educate employees on SOX data retention policies, legal requirements, and proper document handling and security protocols.
• Conduct regular internal audits. The goal is to verify record retention practices align with SOX rules.
• Obtain an additional perspective. Collaborate with external auditors to identify potential compliance gaps.

The Challenges of SOX Compliance

Reporting Accuracy and Record Maintenance

Achieving SOX compliance is challenging for organizations, especially regarding maintaining accurate reporting and data retention.

The major challenges companies face in SOX compliance are:

Challenge of accurate reporting and supporting documentation.

Ensuring that all financial reports are accurate, complete, and trustworthy is among SOX’s core requirements. In reality, it is a challenge for at least three reasons:

1. Risk of data inconsistency – Financial data could be gathered from multiple departments, systems, and other sources, raising the risk of errors in reporting.
2. Risk of human errors – This is especially critical in cases involving manual data entry, human-led calculations, or reporting mistakes.
3. Failure to adapt to new reporting processes – This happens when the U.S. Securities and Exchange Commission (SEC) and Public Company Accounting Oversight Board (PCAOB) update SOX reporting guidelines, and companies need to adapt their processes to align with these new regulations.

Managing high volumes of records can be costly.

SOX requires long data storage periods – at least seven years. These requirements increase storage costs and complicate data retrieval processes. Growing storage expenses include spending on secure databases, cloud storage, backup systems, data encryption, cybersecurity measures, and disaster recovery plans.

Consistent data retention is essential for ongoing compliance.

What does consistency mean when related to SOX data retention? Here is the list of considerations:

• Retention policies. Different departments need to work on a standardized retention policy to avoid gaps in compliance.
• Proper documentation. To avoid challenges related to lost or mishandled records, you need to ensure that your company has established handover procedures, so that when employees leave, it does not result in critical data loss.
• Regular data review and validation. Protecting your data from integrity risks, such as data corruption, duplications, and incoherence, can make it unreliable for compliance audits. 

Remaining SOX Compliant: Key Steps

Data Retention Policy Implementation

The policy should consolidate multiple data retention dates into a single corporate/organizational framework to ensure that records are stored, protected, and accessible for audit and legal enquiries.

Internal Control Report

• Executive management is responsible for establishing, documenting, and overseeing internal control to prevent fraud and errors.
• Companies must implement cybersecurity measures to protect sensitive financial records from unauthorized access.
• Companies need to implement and maintain financial record control processes. SOX requires creating formal policies and procedures to govern how financial records are stored, accessed, and reviewed.
• Training programs are also part of requirements, with a goal to educate employees on data retention, security, and compliance practices.
• SOX-regulated companies must submit an internal financial reporting control report to the SEC with annual financial filings. The report should explain how financial controls are structured and enforced within the organization.
• Companies also must assess and report the effectiveness and weaknesses of the internal control system. If any gaps are found, the management must organize corrective actions. Any flaws or financial control breaches must be disclosed immediately to investors and regulators.

Independent Audit

• Companies must verify the accuracy of management’s internal control reports by an independent registered public accounting firm. Risk areas, control weaknesses, and compliance failures are assessed during the audit.
• During the audit of the company’s internal financial structure, financial reporting system, accounting policies and fraud detection mechanisms are evaluated.  
• The SOX Act mandates that auditors keep audit documents for at least 7 years.

Whistleblower Protection

• Under SOX, employees are encouraged to report illegal corporate activity including fraud, securities violations, and unethical practices. Companies are required to provide anonymous channels to submit a report.
• Whistleblowers are also protected against retaliation. Companies are not allowed to fire, demote, harass, or intimidate employees who submit a report on corporate misconduct.  Retaliation of whistleblowers is classified as a deferral crime under SOX.

Planning SOX Compliance Strategies: Checklist

Step 1. Develop a records retention plan.

You will need a record retention schedule that will serve as a plan for how long your sensitive information will be kept for legal purposes, and when it will be disposed. Besides that, you need to identify and classify your data by types and define which retention periods those types require, i.e., financial statements, accounting records, sales reports, emails, memos, instant messages, bank statements, and invoices. Some data types require indefinite retention, however, it is critical to avoid storing all data forever, because it is impractical and potentially illegal.

Step 2. Digitize documents.

Electronic storage is a preferred method for meeting SOX mandates. This applies to electronic records such as audit logs, financial statements, and email archives.

According to SOX Section 802, public companies must ensure proper storage and maintenance of records, preventing alteration, description, and unauthorized access to sensitive data. Companies are digitizing their documents to ensure long-term compliance instead of keeping paper-based documents. This decision has numerous benefits, such as reduced physical space, enhanced security with encryption and password protection, easier retrieval using advanced search functions and indexing, and easier management of payroll, tax, and ledger records.

Also, SOX requirements include preservation in a nonrewritable, non-erasable format, such as WORM (Write Once, Read Many). With this format, documents cannot be altered or deleted once recorded.

Step 3. Use multiple repositories.

Maintaining multiple repositories is critical for record retention due to ease of data loss in one location. Accidental deletion, cyberattacks, or hardware failure could cause that. Companies should consider distributing their financial records across multiple servers, cloud storage, or off-site physical storage to comply with SOX. Besides that, using various repositories allows for uninterrupted access to data, faster recovery, and reduced downtime without violating compliance requirements.

Common Mistake in Document Management

Data retention topics cannot avoid discussing common mistakes like failing to track and index expiration dates. It is critical because it can hamper operations and expose a company to significant compliance risks. When certifications or regulatory approvals expire, that may result in work stoppages or legal restrictions, affecting productivity and profitability.

If your SOX-regulated company does not have a proper indexing system, it may result in inefficient document retrieval. Employees will have to manually search for expired or soon-to-expire documents, which is inefficient and poses security and compliance risks. Consider categorizing, indexing, and reviewing documents using document management software.

Retention Dates for Documents

Let’s discuss SOX record retention requirements required for different types of records:

Permanent Retention Period

Some documents need to be stored indefinitely, as they have a value for legal or operational purposes. Examples include:

1. Corporate governing documents including notes on shareholder agreements and board meetings.
2. SEC filings, including annual reports in Form 10-K, quarterly reports in Form 10-Q.
3. General Ledger Records, which are complete financial records, are crucial for compliance audits and historical tracking.
4. Employee Payroll Records, such as wage history, tax filings, or benefit records.
5. Bank statements are needed for legal or regulatory review, such as financial audits, during fraud detection cases.
6. Contracts and Leases, such as vendor services agreements or employment contracts.
7. Legal Correspondence, such as legal communications, lawsuit documents, regulatory compliance letters.
8. Communication with regulatory agencies such as SEC and PCAOB.
9. Training Manuals, where employee training and internal policies are documented. These might be necessary for legal matters.
10. Union Agreements, and other labor-related contracts could be used for legal matters.

Retention Period of Seven Years

These documents typically include those that are used for tax, financial or audit purposes:

1. Financial statements and supporting documents, such as income statements, cash flow statements, balance sheets.
2. Audit documents, including audit workpapers, risk analysis, testing results and financial assessments.
3. Records on internal control testing and compliance reports.
4. Bank statements, reconciliation reports and wire transfers.
5. Accounts Payable Ledger – including all outstanding bills and payments.
6. Accounts Receivable Ledger, including customer billing records, outstanding invoices, and payment history.
7. Tax audit reports, tax filing and other supporting documents.
8. Documents on expenses such as employee expenses reimbursements and travel expenses.
9. Documentation on corporate loans, credit facilities and bond issuances.
10. SOX Section 302 certifications, reports, executive signoffs and management attestations.
11. Documents on whistleblower complaints and further investigations and corrective actions.

Retention Period of Five Years

These documents are necessary for financial and operational purposes.

1. Invoices to customers are necessary for tax filings and revenue tracking.
2. Invoices from Vendors, because they serve as a proof of business expenses.
3. Purchase Orders, because they support budgeting and financial audits.
