AICPA standards & SOC reports

๐Ÿ“˜ AICPA Standards & SOC Reports


๐Ÿงพ What Is the AICPA?

The AICPA (American Institute of Certified Public Accountants) is the national professional organization of CPAs in the United States. It sets ethical standards, auditing standards, and information security reporting frameworks, including those used in SOC (System and Organization Controls) reports.

AICPA frameworks are particularly critical for:

  • CPA firms providing IT/financial services
  • Cloud service providers
  • Tax technology vendors
  • Financial institutions handling sensitive data

โœ… What Are SOC Reports?

SOC (System and Organization Controls) Reports are independent audit reports that assess a service organizationโ€™s controls related to security, availability, processing integrity, confidentiality, and privacy. They help build trust between service organizations and their customers.

They are conducted under the AICPAโ€™s Trust Services Criteria and are aligned with attestation standards (e.g., SSAE 18).


๐Ÿงฉ Types of SOC Reports

Type Purpose Audience Focus Area
SOC 1 Financial reporting controls Internal auditors, financial controllers Controls over financial transactions
SOC 2 Security & operational controls IT, compliance teams, regulators, clients Trust Services Criteria
SOC 3 Public assurance General public Same as SOC 2, but summary level
SOC for Cybersecurity Enterprise-wide cyber risk posture Executive management, stakeholders Cybersecurity risk management
SOC for Supply Chain Vendor/manufacturer security & integrity Supply chain partners, regulators Production and delivery controls

๐Ÿ” SOC 2 โ€“ Most Relevant for IT and Data Handling

SOC 2 is the most commonly referenced standard for CPA firms, SaaS companies, and tax tech vendors that manage or process sensitive customer data.

๐Ÿ“‹ SOC 2 Examines 5 Trust Services Criteria:

  1. Security โ€“ Protection from unauthorized access
  2. Availability โ€“ System availability for operation and use
  3. Processing Integrity โ€“ Complete, valid, and accurate system processing
  4. Confidentiality โ€“ Protection of sensitive information
  5. Privacy โ€“ Protection of personal identifiable information (PII)

โžก You can choose which of these criteria your report covers based on your services and client expectations.


๐Ÿ“ SOC Report Types: Type I vs. Type II

Type Covers Time Frame
Type I Design of controls at a point in time One-time snapshot
Type II Design and operational effectiveness over time Typically 6-12 months

โžก Type II is more rigorous and trusted, especially in due diligence and vendor management.


๐Ÿ” Why Are SOC Reports Important for CPAs and Tax Firms?

  • Regulatory compliance: Shows that your firm follows strong IT security and internal control practices
  • Client assurance: Offers transparency and builds trust in B2B relationships
  • Competitive advantage: SOC 2-certified vendors are often preferred
  • Risk management: Helps identify and correct weaknesses in security and operations
  • Due diligence: Large clients and institutions often require SOC reports before onboarding vendors or service providers

๐Ÿ“Š AICPA Trust Services Criteria Framework

SOC 2 and SOC 3 are based on the Trust Services Criteria (TSC), which includes:

Component Description
Control Environment Organizational structure, commitment to integrity
Communication & Information How data flows and is protected
Risk Assessment How risks are identified and addressed
Control Activities Specific procedures and controls in place
Monitoring Activities Ongoing or separate evaluations of performance
Logical & Physical Access Controls Access restrictions and authentication
System Operations Monitoring and maintenance processes
Change Management Managing system and application updates
Incident Response Detecting and responding to security incidents

๐Ÿ“Ž Who Performs SOC Audits?

SOC reports must be performed by an independent CPA firm with experience in attestation services and information security. These firms must follow the AICPAโ€™s Statement on Standards for Attestation Engagements (SSAE 18).


๐Ÿ› ๏ธ How to Prepare for a SOC 2 Audit

  1. Conduct a readiness assessment
  2. Identify and document all controls related to the selected Trust Services Criteria
  3. Implement missing controls (e.g., encryption, access logs, MFA)
  4. Train staff on control-related responsibilities
  5. Choose between Type I or Type II based on client needs
  6. Engage with an AICPA-certified firm to perform the audit
