SOC 2 Renewal: What Changes After Year One

Annual re-audits, why costs drop 30–50%, and how to keep the program running without reliving year one.

Why renewal exists

A SOC 2 report covers a defined period — usually 12 months. Customers doing annual vendor reviews want a current report, so most companies re-audit every year with overlapping or contiguous periods. Let it lapse and the next security questionnaire gets awkward.

What the re-audit looks like

Same structure, less drama: scoping (lighter — the system description mostly carries over), evidence testing across the new period, fieldwork, report. The observation period is now just "the last 12 months of normal operations" rather than a special project. Most companies report 4–8 weeks of active effort versus the months year one consumed.

Why it costs less

Published guidance suggests year-two costs drop 30–50%: policies exist, tooling is deployed, evidence habits are muscle memory, and there's no readiness assessment or remediation project. What remains is the annual audit fee plus tooling subscriptions. The fee itself may still rise with headcount growth — that's the main variable.

Keeping it cheap

• Don't let evidence habits decay. The #1 cause of expensive renewals is rebuilding a year's evidence in a panic.
• Track control changes. New systems, new vendors, new data flows — log them as they happen so scoping isn't a forensic exercise.
• Re-test your DR plan annually. It's the most commonly lapsed control between audits.
• Renegotiate on value, not just price. A second-year quote should reflect that you're an easy, organized client.

Switching auditors

Allowed and common. The new firm will want your prior report and system description; expect a slightly heavier first year with them as they re-baseline. Time the switch so periods stay contiguous — a gap in coverage is worse than a higher fee. Compare renewal quotes.
