SOC 2 Type 1 vs Type 2
Answer
A SOC 2 Type 1 report covers whether a company's controls are suitably designed as of one date. A Type 2 report covers design and operating effectiveness throughout a specified period, as CPA firm Johanson LLP summarized the AICPA definitions on March 10, 2026. Wolf & Company says Type 2 suits companies that need to show clients their controls work over time.
What each report tests
- Type 1: the auditor reviews the system description and whether controls are suitably designed as of a specified date.
- Type 2: the auditor reviews the same things and tests whether the controls operated effectively throughout a specified period.
- Wolf & Company, a CPA firm, wrote on Oct. 14, 2023 that a Type 1 does not assess whether controls are operating effectively.
- Both reports are issued by a CPA firm under AICPA standards.
How long the Type 2 period runs
The AICPA definition says a specified period. CPA firms set the length with the client.
Johanson LLP, on March 10, 2026, puts the minimum at three months for a first Type 2 and says some customers want six months.
Wolf & Company, on Oct. 14, 2023, gives six to 18 months and says 12 months is common.
How to choose
- Start with a Type 1 if a deal needs a report soon and your controls are new. Wolf & Company calls this a foundation for a first audit.
- Begin the Type 2 observation period once controls are running.
- Pick the trust services categories in scope. The AICPA lists security, availability, processing integrity, confidentiality and privacy.
- Watch the criteria. The AICPA posted exposure drafts of proposed 2027 Trust Services Criteria on Oct. 26, 2026.
