SOC 1 vs SOC 2: Which Audit Does Your Company Actually Need in 2026?
A prospect sends over a security questionnaire. Your sales team scrambles to figure out what kind of SOC report the deal requires. Meanwhile, your CFO mentions that your payroll processor's client is asking about a SOC 1. And your CTO is convinced the company needs "a SOC 2."
The confusion is understandable. SOC 1 and SOC 2 are both audit frameworks governed by the AICPA (American Institute of Certified Public Accountants), both are performed by licensed CPA firms, and both produce formal attestation reports. But they evaluate fundamentally different things -- and choosing the wrong one wastes months and tens of thousands of dollars.
This guide clarifies exactly what each audit covers, who asks for which, when you might need both, and how to move from decision to certification efficiently.
The Fundamental Difference
SOC 1 evaluates controls relevant to financial reporting. Specifically, it addresses whether your organization's controls could affect the accuracy and completeness of a client's financial statements. The formal term is Internal Controls over Financial Reporting (ICFR).
SOC 2 evaluates controls relevant to security, availability, processing integrity, confidentiality, and privacy. These five categories are called the Trust Services Criteria (TSC), and they cover how your organization handles and protects data -- regardless of whether financial reporting is involved.
In simpler terms: SOC 1 asks, "Can we trust this vendor not to break our financial numbers?" SOC 2 asks, "Can we trust this vendor to keep our data secure?"

When You Need SOC 1
You need a SOC 1 if your service directly touches, processes, or could affect the financial data that appears on your clients' financial statements. The operative question is: Does your organization's work product flow into your client's general ledger, financial reports, or financial disclosures?
Common scenarios that require SOC 1:
- Payroll processing companies. You calculate wages, withholdings, and tax remittances that your clients record as expenses and liabilities.
- Payment processing platforms. Transaction data you handle directly affects your clients' revenue recognition and accounts receivable.
- Loan servicing and origination software. Interest calculations, payment allocations, and balance reporting affect your clients' financial statements.
- Claims processing platforms. Insurance or benefits claims you adjudicate affect your clients' reserves and loss estimates.
- Fund administration services. NAV calculations, investor allocations, and fee computations directly impact your clients' reported figures.
- Managed hosting for financial applications. If you host a client's ERP or accounting system, the availability and integrity controls around that hosting are relevant to their ICFR.
The key indicator: if your clients' external auditors are asking about your controls as part of their annual financial audit, they almost certainly want a SOC 1.
When You Need SOC 2
You need a SOC 2 if your clients care about how you protect their data, maintain system availability, or ensure the integrity and privacy of the information they entrust to you. The question here is: Does your organization store, process, or transmit data that your clients consider sensitive, proprietary, or regulated?
Common scenarios that require SOC 2:
- B2B SaaS platforms. Enterprise buyers conducting vendor security assessments will request your SOC 2 report.
- Cloud infrastructure and managed services providers. Clients need assurance that their workloads are protected.
- Healthcare IT companies. While HIPAA is the primary regulation, many healthcare organizations also require SOC 2 as part of their vendor risk management.
- Data analytics and business intelligence platforms. Clients sharing proprietary data need confidence in your security and confidentiality controls.
- HR tech and payroll platforms (for the data security side). While the financial processing may require SOC 1, the sensitive employee data you hold may also trigger SOC 2 requirements.
- Any company selling to enterprises with formal Third-Party Risk Management (TPRM) programs. SOC 2 has become the de facto standard for vendor security assessment in enterprise procurement.
The key indicator: if your prospects' security teams are asking about encryption, access controls, incident response, and data handling during the sales process, they want a SOC 2.
Can You Need Both?
Yes -- and it is more common than most companies expect. Organizations that both process financial data and handle sensitive non-financial data frequently need both SOC 1 and SOC 2.
Examples of companies that often need both:
- Payroll and HR platforms (ADP, Gusto, and similar): SOC 1 for the payroll calculations that affect financial statements, SOC 2 for the security and privacy controls around sensitive employee data (SSNs, salary information, benefits data).
- Payment processors that also store transaction analytics or customer data: SOC 1 for the payment processing controls, SOC 2 for data security.
- Financial SaaS companies offering cloud-based accounting, expense management, or invoicing: SOC 1 for the financial processing accuracy, SOC 2 for the cloud security posture.
The practical impact of needing both:
The good news is that significant control overlap exists between SOC 1 and SOC 2. Controls around access management, change management, system monitoring, and incident response are typically tested in both. Organizations that pursue both can often share 40-60% of the control evidence between the two audits. Coordinating the observation periods and engaging the same CPA firm for both can further reduce cost and effort.
Cost Comparison
Understanding the full cost requires looking beyond audit fees.
SOC 1 Total Cost of Ownership
| Cost Component | DIY / In-House | With Consulting Firm | With QuickTrust |

Timeline Comparison
SOC 1 Timeline (Type 2)
| Phase | Duration | Key Activities |
|---|---|---|
| Scoping and assessment | 2-4 weeks | Identify services in scope, map financial data flows, define control objectives |
| Control design and documentation | 4-8 weeks | Write control descriptions, define testing attributes, create process narratives |
| Observation period | 6-12 months | Controls operate, evidence is collected continuously |
| Audit fieldwork | 4-6 weeks | CPA firm tests controls, samples evidence |
| Report issuance | 2-4 weeks | Final report drafted and delivered |
SOC 2 Timeline (Type 2)
| Phase | Duration | Key Activities |
|---|---|---|
| Gap assessment | 2-3 weeks | Map current state against Trust Services Criteria, identify gaps |
| Remediation and implementation | 4-10 weeks | Implement missing controls, deploy tooling, write policies |
| Observation period | 6-12 months | Controls operate, evidence is collected continuously |
| Audit fieldwork | 4-6 weeks | CPA firm tests controls against TSC |
| Report issuance | 2-4 weeks | Final report drafted and delivered |
Both audits share similar timelines, with the observation period representing the longest phase. The key difference is in the preparation phase: SOC 1 requires deep mapping of financial data flows and client-impact analysis, while SOC 2 focuses on security control implementation.
Decision Framework: How to Choose
Use this sequence of questions to determine the right audit:
Question 1: Does your service affect your clients' financial statements?
- Yes: You need SOC 1 (and possibly SOC 2 as well -- continue to Question 2).
- No: Skip SOC 1, move to Question 2.
Question 2: Do your clients' security or procurement teams ask about data protection, access controls, or system security?
- Yes: You need SOC 2.
- No: You may not need SOC 2 today, but if you sell to enterprise B2B buyers, the request is likely coming soon.
Question 3: Do you handle both financial data and sensitive non-financial data for clients?
- Yes: Plan for both SOC 1 and SOC 2. Coordinate the audits to maximize control overlap and minimize cost.
- No: Proceed with whichever single audit matches your primary use case.
Question 4: Are your clients' external auditors asking for your controls report?
- Yes: SOC 1, specifically. External financial auditors reference SOC 1 reports when evaluating their clients' ICFR.
- No: SOC 2 is more likely the right fit.
Common Mistakes to Avoid
Mistake 1: Assuming SOC 2 covers financial reporting controls. SOC 2 does not address ICFR. If your client's auditor asks for a SOC 1 and you hand them a SOC 2, they will ask again for the SOC 1. The two are not interchangeable.
Mistake 2: Starting with the wrong audit. If you are a fintech company processing transactions and you begin with SOC 2 because it feels more "standard," you may find that your largest clients actually need SOC 1. Validate with your top five customers before starting.
Mistake 3: Treating SOC 1 and SOC 2 as completely separate projects when you need both. The overlapping controls (access management, change management, monitoring, incident response) should be designed once and tested for both reports. Running parallel but uncoordinated audits doubles the effort unnecessarily.
Mistake 4: Ignoring the Type 1 vs Type 2 decision. Both SOC 1 and SOC 2 come in Type 1 (point-in-time) and Type 2 (period-of-time) variants. Most enterprise buyers require Type 2 eventually, but Type 1 can unblock deals while you build toward Type 2.
How QuickTrust Supports Both SOC 1 and SOC 2
QuickTrust's approach eliminates the ambiguity and execution overhead associated with SOC audits. Here is how:
Framework mapping and gap assessment. QuickTrust's platform maps your current controls against both SOC 1 (ICFR objectives) and SOC 2 (Trust Services Criteria), identifying exactly where gaps exist and which controls can be shared across both reports.
Engineering-led implementation. QuickTrust does not just identify gaps -- the engineering team implements the fixes. IAM configurations, encryption at rest and in transit, logging pipelines, network segmentation, CI/CD security controls, and policy documentation are all handled by QuickTrust's security and DevOps engineers. Your internal team commits approximately two hours per week.
Audit coordination. QuickTrust manages the relationship with the CPA firm, organizes evidence collection, and ensures the observation period produces clean, auditable data. For organizations needing both SOC 1 and SOC 2, QuickTrust coordinates the audit scopes to maximize shared controls and reduce total cost.
Continuous compliance. After certification, QuickTrust monitors for control drift, maintains the evidence portal, and ensures you are always ready for annual re-examination -- not scrambling to rebuild evidence from scratch every 12 months.
The result: a 100% audit pass rate across 100+ audits, with most organizations moving from gap assessment to audit-ready in 6-10 weeks.
