Type Differences

SOC 1 Type I vs. Type II

SOC 1 reports are available as Type I and Type II, each addressing a different level and period of assurance over relevant controls.

Type I
Evaluates whether relevant controls are suitably designed and implemented as of a specified date.
Type II
Evaluates control design and operating effectiveness throughout a defined review period.
Choosing the Right Report
Type I supports point-in-time assurance. Type II provides evidence of sustained control operation over a defined period.

Planning depends on scope, control maturity, evidence readiness, and the reporting period selected for the SOC 1 examination.

Point-in-time examination. Timing depends on scope, documentation quality, control readiness, and auditor coordination.

Period-based review. Requires consistent evidence that controls operated effectively over time.

SOC 1 Type I is appropriate when stakeholders need assurance over control design and implementation as of a specified date. It is often used for an initial reporting cycle, newly implemented controls, or a defined customer requirement before progressing to a Type II examination.
SOC 1 Type II is appropriate when relevant controls have operated for a defined period and stakeholders need assurance over both design and operating effectiveness. It provides evidence of how controls performed throughout the review period and is commonly requested for recurring assurance.
Type I addresses whether controls are suitably designed and implemented as of a specified date, while Type II also evaluates whether those controls operated effectively throughout a defined period.
The appropriate report depends on stakeholder requirements, control maturity, and timing. Organizations may begin with Type I for point-in-time assurance and move to Type II when they need evidence of sustained operating effectiveness.
