How long does a SOC 2 audit take?
A SOC 2 Type 1 usually takes one to three months end to end, while a Type 2 adds an observation window of three to twelve months. Readiness prep, not the audit itself, is often the longest phase.
The full answer
The honest answer splits by report type. Per AICPA guidance and common market practice, a SOC 2 Type 1 examines your controls at a single point in time and typically runs one to three months from kickoff to report. A Type 2 tests whether those controls operated effectively across an observation window, so it takes longer overall: the window itself is usually three to twelve months, plus prep and fieldwork on either side.
Most of the calendar time is not the auditor's testing — it is readiness. Writing policies, standing up controls, and gathering evidence can take a few weeks to several months depending on how mature your security program already is. GRC platforms such as Vanta, Drata, Secureframe, and Sprinto automate much of that evidence collection and can meaningfully shorten prep.
Fieldwork — the auditor's actual review and testing — is comparatively short, often a couple of weeks, followed by report drafting. When your auditor has a confirmed integration with your GRC platform, they can pull evidence directly, which trims back-and-forth during this phase.
To plan realistically, work backward from the date a customer needs your report. If you have a hard deadline, a Type 1 first (then a Type 2) is a common way to show progress quickly. SOC 2 audits booked through the AuditNex network start at $2,500 promotionally and average about $5,000, per our 2026 rate card, and the timeline estimator can map your scope to a realistic schedule.

Related questions
Can I speed up a SOC 2 audit?
Yes, partly. You can compress readiness and fieldwork with a GRC platform, a Type 1 or 3-month Type 2 first, and fast evidence responses — but a Type 2 observation window still has to run its full length.
Can a SOC 2 Type 2 observation period be 3 months?
Yes. Three months is the shortest observation window most auditors will accept for a SOC 2 Type 2, so a 3-month period is valid and common for a first report. Longer windows give buyers more assurance.
Do SOC 2 audits happen on-site or remotely?
Almost always remotely. Most SOC 2 audits are conducted entirely over video calls, screen shares, and secure evidence uploads, since the evidence is digital. On-site visits are rare and usually only relevant if you run your own physical data centers.
How long does the SOC 2 report take after fieldwork ends?
Most SOC 2 reports are drafted and delivered within a few weeks of fieldwork ending, though timing varies by firm and how quickly you clear any open evidence items. There is no AICPA-set deadline for delivery.
How many internal hours does a SOC 2 audit take my team?
There is no official figure. Most internal effort is front-loaded during readiness, not the audit itself. Expect a designated owner to spend meaningful part-time hours over the prep window, plus lighter time answering auditor questions during fieldwork.
How often do I need a SOC 2 audit?
Once a year in practice. No AICPA rule sets a frequency, but buyers treat a SOC 2 report as current for twelve months from its period end, so most companies renew annually with a rolling Type 2 to avoid gaps.
