SOC 1 vs. SOC 2 – How They Are Different & Which Report You Need

SOC 1 and SOC 2 are both audit reports issued under AICPA standards, but they serve very different purposes. A SOC 1 report focuses on internal controls that affect your clients’ financial statements — it matters if your service touches payroll, billing, or financial data. A SOC 2 report focuses on how you protect data — security, availability, confidentiality, processing integrity, and privacy. If a customer or partner asks you to prove your data security practices, you likely need a SOC 2. If their financial auditors need to review your controls, you likely need a SOC 1. Some businesses need both.

Every year, more businesses get asked for a SOC report by their clients — and the first question that comes up is: which one do I need? SOC 1 vs. SOC 2 is honestly one of the most common points of confusion in the compliance world. They sound similar, they’re both from AICPA, and they can even overlap. But they are built for completely different situations.

This guide breaks it all down in plain language — no jargon overload, no unnecessary complexity. Whether you are a startup getting your first audit request or a growing company trying to sort out your compliance roadmap, this should help you make the right call.

What Is a SOC Report and Where Does It Come From?

SOC stands for System and Organization Controls. These are audit reports created by the American Institute of Certified Public Accountants (AICPA). They are designed to help service organizations prove to their clients that their internal controls are working as they should.

Think of a SOC report like a formal report card — written by an independent auditor (a CPA firm) — that tells your clients: “Yes, this company has the right controls in place, and we checked that they actually work.” There are a few types of SOC reports: SOC 1, SOC 2, SOC 3, and SOC for Cybersecurity. But by far the two you will hear about most often are SOC 1 and SOC 2. That’s what we are focusing on here.

SOC 1 vs. SOC 2 in one sentence: SOC 1 covers controls that impact your clients' financial reporting. SOC 2 covers controls that impact your clients' data security and privacy.

SOC 1 vs. SOC 2 — The Core Difference

Here is the simplest way to think about this:

SOC 1 — If your service affects how your client reports money, you need a SOC 1. Examples: payroll processors, billing platforms, claims management.
SOC 2 — If your service stores, processes, or transmits your client’s data, you likely need a SOC 2. Examples: SaaS platforms, cloud providers, data centers, managed IT services.

The big question your auditor will ask is: Does your service affect your client’s financial statements, or does it affect their data security? The answer usually points clearly to one report — or sometimes both.

What Is a SOC 1 Report?

A SOC 1 report is a formal audit of the internal controls at a service organization that could affect the accuracy of a client’s financial statements. It falls under the AICPA standard known as SSAE 18 AT-C 320.

Who asks for SOC 1 reports? Usually, the financial auditors of your clients. When a big company gets its books audited, their auditors want to know: “If this company uses a third-party payroll processor, are those controls solid enough that we can rely on them when we audit their financials?”

Who Typically Needs a SOC 1?

Payroll processing companies
Loan servicing platforms
Medical billing and claims processors
Tax preparation software providers
Benefits administration services
Accounting and ERP service providers

Real-world example: If you run a payroll platform and your clients are mid-size businesses, their financial auditors will likely request a SOC 1 report from you during audit season. This is a very common scenario.

What Is a SOC 2 Report?

A SOC 2 report is an audit of how a service organization manages and protects its systems and data. It is built around the AICPA’s Trust Services Criteria (TSC), which covers five areas:

The Five Trust Services Criteria

Security — required in every SOC 2
Availability — system uptime and reliability
Processing Integrity — accurate, complete processing
Confidentiality — protecting sensitive data
Privacy — handling personal information responsibly

Who Typically Needs a SOC 2?

SaaS and cloud software companies
Data centers and hosting providers
Managed IT service companies
AI and analytics platforms
HR tech and CRM providers
Healthcare technology companies

The security criteria (also called the “Common Criteria”) is the only one you must always include. The other four are optional — you add them based on what makes sense for your services. For example, a cloud storage company might add Availability and Confidentiality. A healthcare SaaS might add Privacy.

SOC 2 reports are typically requested by enterprise procurement teams, compliance officers, and IT security teams — not financial auditors. In 2026, SOC 2 has become almost a baseline expectation for any B2B software company working with enterprise clients.

SOC 1 vs. SOC 2 Comparison

Here is a clean breakdown so you can see the differences at a glance:

Factor	SOC 1 Report	SOC 2 Report
Primary focus	Financial reporting controls	Data security and privacy controls
Governing standard	SSAE 18 AT-C 320	SSAE 18 AT-C 105 / SSAE 21 AT-C 205
Who asks for it	Financial auditors, CFOs	Enterprise clients, IT/security teams, procurement
Control framework	Custom control objectives (defined by your business)	AICPA Trust Services Criteria (pre-defined)
Required criteria	No fixed criteria — objectives defined per service	Security (Common Criteria) is always required
Report types	Type I and Type II	Type I and Type II
Typical industries	Payroll, billing, loan servicing, benefits admin	SaaS, cloud, managed IT, data analytics, healthcare tech
Audience	User entities and their financial auditors	User entities, regulators, partners, compliance teams
Covers IT controls?	Yes, where they affect financial data	Yes, more broadly across all five criteria

SOC 1 Type 2 vs. Type 1 — What's the Difference?

Within both SOC 1 and SOC 2, there are two sub-types: Type I and Type II. This is where a lot of people get confused — so let’s keep it simple.

Feature	Type I	Type II
What it looks at	Design of controls at a single point in time	Design + operating effectiveness over a period of time
Testing period	A specific date (e.g., "as of December 31, 2025")	Minimum 6 months (most prefer 12 months)
Level of assurance	Lower — confirms controls exist	Higher — confirms controls work consistently
Best for	Getting started quickly, new programs	Ongoing compliance, client requirements, trust-building
What clients prefer	Acceptable as a first step	Strongly preferred by enterprise clients

A SOC 1 Type 2 report (also written as SOC 1 Type II) tests whether a service organization's financial reporting controls were actually operating as designed over a minimum 6-month period. It is the gold standard when your clients' financial auditors need to rely on your controls.

Most clients — especially enterprise ones — will eventually ask for a Type II, not just a Type I. A Type I is fine to start with if you need a report quickly, but plan to move toward a SOC 1 Type 2 report or SOC 2 Type II as your ongoing report.

Which Report Do You Actually Need?

Here is the honest answer: it depends on what your service does and who is asking for the report. But these questions can guide you pretty quickly:

Quick Decision Guide

Does your service directly process financial transactions, payroll, or billing for your clients? → You likely need a SOC 1.

Is a financial auditor or CFO asking you for a report? → They want a SOC 1.

Do you store, manage, or process your clients' business or personal data in the cloud? → You likely need a SOC 2.

Is a security team, IT manager, or enterprise procurement team asking for a report? → They want a SOC 2.

Does your service touch both financial data AND general business data? → You may need both reports.

If you are still unsure, the best move is to talk to a compliance expert who can review your specific services and tell you exactly what fits. At JS Certification, we do this assessment as part of our onboarding — no guesswork needed.

Do You Need Both SOC 1 and SOC 2?

Yes, some organizations genuinely need both. It is more common than you might think.

Imagine you run a platform that processes payroll for HR departments and stores sensitive employee data in the cloud. The client’s financial auditors need your SOC 1 to review financial controls. But the client’s IT and security team also needs your SOC 2 to confirm data security practices. The good news is that when both audits happen at the same time with the same audit firm, there is often significant overlap in testing — which means less work and lower cost overall.

Pro tip: If you think you might need both, schedule the SOC 1 and SOC 2 engagements together. Shared control testing can save you time and reduce the audit burden on your team.

Frequently Asked Questions

Is a SOC 2 harder to get than a SOC 1?

Not necessarily harder, but different. SOC 2 follows a pre-defined framework (the Trust Services Criteria), so the scope is more standardized. SOC 1 is more flexible — the control objectives are shaped around your specific services. Both require real effort and proper controls. The complexity depends more on the size and maturity of your organization than on which report type you pick.

Can a SOC 2 replace a SOC 1?

No. These are two separate reports under different standards and they answer different questions. A financial auditor who needs a SOC 1 to assess the impact on their client's financial statements will not accept a SOC 2 in its place. They serve distinct purposes.

What is a SOC 1 Type 2 report exactly?

A SOC 1 Type 2 report is a detailed audit that covers both the design and the operating effectiveness of a service organization's controls related to financial reporting. It spans a defined period — usually 6 to 12 months — and is the type that most financial auditors require when they need to rely on your controls as part of their audit of your client's financials.

How long does a SOC audit take?

A Type I audit can typically be completed in a few weeks to a couple of months once your controls are in place. A Type II audit requires a minimum six-month observation period, so the full process from readiness to report issuance often takes 8–14 months depending on how prepared you are going in.

What is the difference between soc1 vs soc2 compliance?

SOC 1 compliance means your internal controls over financial reporting have been independently audited and found to be designed and operating effectively. SOC 2 compliance means your controls for data security, availability, privacy, and other trust criteria have been independently verified. Both are evidence of organizational maturity — just in different domains.

Does my startup need a SOC audit?

If you are selling to enterprise clients — yes, almost certainly. Enterprise procurement and security teams increasingly require SOC 2 as a baseline before signing a contract. Starting the process early (even with a readiness assessment) is much easier than rushing to get compliant when a big deal is on the line.

Final Thoughts — SOC 1 and SOC 2 in 2026

The compliance landscape in 2026 has made SOC reports more important than ever. Enterprise clients are more security-conscious, supply chain risk is a top concern, and auditors are increasingly thorough. Getting the right report — and getting it right — is not just about compliance. It is about building trust with your clients.
