RIA Compliance Calendar 2026: Quarterly Filing Patterns & Key Deadlines

The amended Regulation S-P creates a compliance watershed moment for smaller Registered Investment Advisers. While larger RIAs with $1.5 billion or more in assets under management faced their deadline in December 2025, smaller firms have until June 3, 2026 to implement cybersecurity and data protection protocols.

This deadline isn't merely administrative; it represents a fundamental shift in how RIAs must approach client data protection. The amendments require detailed incident response programs, formal vendor oversight procedures, and specific notification timelines that many smaller firms haven't previously faced. Industry compliance experts emphasize that contract negotiations with service providers alone can take several months, making immediate preparation essential.

Q1 2026: Form ADV and Annual Review Requirements

March 31 Form ADV Annual Amendment

The Annual Updating Amendment to Form ADV remains the cornerstone of RIA compliance obligations. For firms operating on a December 31 fiscal year-end, the March 31, 2026, deadline requires updates covering assets under management, fee structures, disciplinary actions, and material business changes from the previous year.

This filing extends beyond simple data updates. Firms must ensure their ADV Part 2A accurately reflects current operations, including any new services, investment strategies, or affiliated relationships developed during 2025. The SEC continues to scrutinize discrepancies between ADV filings and actual firm practices during examinations, making accuracy critical.

Annual Compliance Review Documentation Best Practice

Rule 206(4)-7 mandates that RIAs conduct annual reviews of their compliance policies and procedures. Following an amendment effective November 13, 2023, these reviews must be documented in writing—a shift from previous practices where verbal assessments were acceptable. The written documentation should demonstrate that the review assessed both policy adequacy and implementation effectiveness.

Compliance officers should approach this requirement systematically, evaluating whether existing policies address current business operations, regulatory changes, and identified risks. The documentation becomes vital during SEC examinations, as examiners expect to see evidence of thorough, objective assessment rather than cursory checkbox exercises.

February 17, 2026 Form 13F Filing (Q4 2025 Large Holdings)

RIAs with discretionary authority over $100 million or more in Section 13(f) securities must file Form 13F quarterly. The February 17, 2026 deadline covers Q4 2025 holdings, with subsequent filings due 45 days after each quarter-end. This creates a predictable rhythm: February 17, May 15, August 14, and November 16 throughout 2026.

Accuracy in Form 13F filings remains paramount, as misreporting can trigger SEC inquiries. Firms should maintain robust reconciliation procedures between their portfolio management systems and 13F reporting to ensure consistency across all submissions.

Regulation S-P Implementation Checklist

Vendor Management and 72-Hour Notification Under Regulation S-P

The amended Regulation S-P fundamentally changes vendor relationship management. Service providers must now notify RIAs within 72 hours of detecting unauthorized access to systems containing client information. This requirement applies broadly to any entity that "receives, maintains, processes, or otherwise is permitted access to customer information," including CPAs, managed service providers, and specialized software vendors.

Compliance officers should begin vendor assessments immediately, as contract renegotiations often require significant lead time. Major custodians likely already comply with these standards, but smaller vendors may need months to implement necessary procedures or update their incident response capabilities.

Client Breach Notification Within 30 Days

When unauthorized access to sensitive client information occurs, RIAs must notify affected individuals as soon as practicable, but no later than 30 days after discovery. This notification requirement includes specific content elements: breach description, affected information types, protective measures taken, contact information for client questions, and detailed guidance on credit monitoring and fraud prevention.

The notification obligation applies unless the RIA determines, after reasonable investigation, that sensitive information hasn't been and isn't reasonably likely to be used for substantial harm or inconvenience. This determination requires careful documentation and often legal consultation.

Incident Response Program Updates

Every RIA must now maintain a formal incident response program designed to detect, prevent, respond to, and recover from unauthorized access. The program triggers immediately upon any unauthorized data access incident—including minor or accidental breaches by employees.

Effective incident response programs include clear trigger definitions, assigned team roles, documented procedures, and regular testing through tabletop exercises. Firms should update their programs to address the expanded scope of covered information, which now includes data received from other financial institutions.

Five-Year Recordkeeping Requirements

Regulation S-P amendments introduce recordkeeping obligations spanning five years, with the first two years maintained in easily accessible locations. Required records include written policies and procedures, documentation of detected unauthorized access, investigation determinations regarding notification requirements, and all written vendor contracts or agreements.

This documentation becomes vital during regulatory examinations, as SEC examiners will review evidence of policy implementation, incident handling, and vendor oversight. Firms should establish systematic record retention processes that organize these materials for efficient retrieval.

Quarterly Filing Patterns Throughout 2026

Form 13F Recurring Deadlines: February 17, May 15, August 14, November 16

Form 13F filings follow a predictable quarterly cadence that allows firms to establish systematic processes. Each deadline falls approximately 45 days after quarter-end: Q4 2025 holdings due February 17, Q1 2026 due May 15, Q2 2026 due August 14, and Q3 2026 due November 16.

This structured timeline enables compliance teams to develop standardized procedures for data collection, reconciliation, and submission. Firms should maintain consistent methodologies across quarters to ensure accuracy and facilitate efficient preparation.

Mid-Year Cybersecurity Assessment Best Practices

The SEC's continued emphasis on cybersecurity makes mid-year assessments increasingly important. Q2 provides an optimal window for testing incident response plans, reviewing vendor protocols, and conducting employee phishing simulation exercises before peak examination season begins.

Compliance officers should use this period to evaluate whether current risk assessments accurately reflect the firm's threat environment. SEC examiners recommend moving beyond simple low, medium, high risk designations toward more detailed risk matrices that consider specific threat vectors and potential impacts.

Common Compliance Calendar Pitfalls

Manual Tracking System Failures

Spreadsheets and static checklists create inherent risks in compliance management. These manual systems often lead to missed reminders, lost documentation, and incomplete task tracking. When multiple staff members access and modify shared spreadsheets, version control becomes problematic, potentially resulting in conflicting information or overwritten updates.

The complexity of modern RIA compliance obligations, spanning quarterly filings, annual reviews, vendor management, and cybersecurity protocols, exceeds the capabilities of manual tracking methods. Firms relying on email reminders and individual calendars frequently experience gaps when staff members are unavailable or overwhelmed.

Staff Turnover and Process Gaps

Personnel changes create significant compliance vulnerabilities when responsibilities aren't properly centralized or documented. Key compliance tasks may fall through organizational cracks during transitions, especially if departing employees maintained institutional knowledge in informal systems.

Effective compliance programs assign clear ownership for each recurring obligation while maintaining backup coverage. Cross-training and detailed procedure documentation ensure continuity regardless of staffing changes. This systematic approach prevents knowledge silos that create single points of failure.

Structured Technology Eliminates Deadline-Driven Stress

Modern compliance management platforms transform how RIA firms approach regulatory obligations. Instead of scrambling to meet individual deadlines, structured technology creates predictable workflows that distribute compliance activities throughout the year. Automated reminders, centralized documentation, and integrated task tracking eliminate the feast-or-famine cycle that characterizes manual compliance management.

Purpose-built compliance software provides dashboards showing what's complete, what's due, and what's at risk. This visibility enables proactive resource planning and prevents last-minute crises. When regulatory examinations occur, firms with organized digital compliance trails can efficiently respond to examiner requests while demonstrating systematic adherence to requirements.

The scalability of technology-driven compliance becomes particularly valuable for growing RIAs. Whether onboarding new advisors, expanding client bases, or entering new jurisdictions, robust compliance platforms ensure firms won't outgrow their control systems. The investment in structured compliance technology pays dividends through reduced operational stress, improved regulatory relationships, and enhanced firm reputation.
