PCI SAQ Basics and Types – Guide to Choosing and Completing Your Questionnaire

---

The Payment Card Industry Data Security Standard (PCI DSS) defines various levels of PCI compliance based on the volume of payment transactions per year an organization handles. Large-scale entities (over 6 million transactions) typically complete a Report on Compliance (RoC), while smaller ones (below 6 million transactions) validate compliance through a Self-Assessment Questionnaire (PCI SAQ). If you’ve determined that you only need to complete an SAQ, this article will help you understand its purpose, the different SAQ types, and how to fill it out.

What Is a PCI Self-Assessment Questionnaire (SAQ)?

A PCI SAQ is a validation tool designed for merchants and service providers that do not require a full RoC. It assesses whether your organization meets the PCI DSS requirements for storing, processing, or transmitting cardholder data. SAQs contain yes/no questions on areas such as network security, system configurations, and access controls. They also include an Attestation of Compliance (AOC), where you formally confirm that your environment aligns with PCI DSS standards.

Why PCI SAQ Matters?

• Consumer Trust: By proving you protect payment data, you boost customer confidence.
• Regulatory Requirements: Non-compliance can lead to fines, legal issues, or suspension of card-processing privileges.
• Enhanced Security Posture: Regularly evaluating your data protection measures helps you detect vulnerabilities early and mitigate evolving cyber threats.

Who Needs to Complete a PCI DSS Self-Assessment Questionnaire?

Any organization that stores, processes, or transmits cardholder data, even a few transactions per year, must follow PCI DSS guidelines. Generally, SAQs are for:

• Merchants and service providers handling fewer transactions (under 6 million annually) or not mandated to complete a full RoC.
• E-commerce and brick-and-mortar businesses that do not require an on-site audit by a Qualified Security Assessor (QSA).

If your organization’s transaction volume exceeds certain thresholds, or if you handle more complex processing, you may need an external audit (RoC). When in doubt, consult your acquiring bank or a QSA to confirm eligibility.

Types of PCI SAQs and Their Applicability

The PCI Security Standards Council offers multiple SAQ types to reflect diverse payment environments. Choosing the correct one is essential for accurate compliance validation.

SAQ A

Who It’s For: Merchants that outsource all card data processing to PCI DSS compliant third parties (e.g., an e-commerce site that redirects to a secure payment gateway).

Key Point: No cardholder data is stored, processed, or transmitted through the merchant’s own systems.

SAQ A-EP

Who It’s For: E-commerce merchants outsourcing payment processing but who still control the web page that can affect transaction security (e.g., a payment form embedded on your site).

Key Point: You don’t handle card data directly, but your website environment may influence the security of the payment transaction.

SAQ B

Who It’s For: Merchants using only imprint machines or standalone dial-out terminals with no electronic card data storage.

Key Point: Common for smaller, brick-and-mortar businesses that run simple card-present transactions.

SAQ B-IP

Who It’s For: Merchants using standalone, IP-connected terminals without storing cardholder data.

Key Point: Similar to SAQ B, but terminals connect via the internet, so network security is critical.

SAQ C

Who It’s For: Merchants processing card data via payment applications connected to the internet but who do not store card data electronically.

Key Point: Applies to slightly more complex in-person or mail-order/telephone order scenarios with internet connectivity.

SAQ C-VT

Who It’s For: Merchants manually entering transactions into a virtual terminal provided by a PCI DSS compliant third party.

Key Point: Often used by call centers, mail order, or other environments where cardholder data is typed into an online form but not stored locally.

SAQ P2PE

Who It’s For: Merchants using only hardware terminals under a validated Point-to-Point Encryption (P2PE) solution.

Key Point: Data is encrypted at the terminal, minimizing the merchant’s PCI scope.

SAQ D

Who It’s For:

• SAQ D for Merchants: Businesses that don’t fit other SAQ categories (often storing or extensively handling cardholder data).
• SAQ D for Service Providers: Entities managing or storing card data on behalf of others (e.g., hosting providers, payment gateways).

Key Point: Covers the most comprehensive PCI DSS requirements and is typically used by more complex or higher-risk organizations.

How to Choose the Right SAQ for Your Business

1. Identify Payment Channels: Determine whether you accept payments in person, online, or through a mix of channels.
2. Outline Data Flows: Map out where cardholder data enters and exits your systems. Check if it’s stored electronically or only on paper.
3. Assess Third Parties: If you outsource payment processing, verify your provider’s PCI DSS compliance.
4. Review PCI DSS Guidelines: Match your specific payment environment to the SAQ descriptions or consult a QSA if needed.

How to Complete and Submit Your PCI DSS SAQ

1. Gather Documentation: Collect policies, logs, and network diagrams. Having everything ready makes it easier to answer SAQ questions accurately.
2. Conduct a Gap Analysis: Compare your current security setup to the PCI DSS requirements. Identify weaknesses or missing controls.
3. Implement Required Controls: Close any compliance gaps, such as updating firewalls, strengthening password policies, or segmenting networks.
4. Fill Out the SAQ: Provide truthful yes/no answers, attach evidence where possible, and ensure no inconsistencies.
5. Sign the Attestation of Compliance (AOC): Confirm you meet the necessary requirements and have all controls in place.
6. Submit Documentation: Provide your completed SAQ and AOC to your acquiring bank or the relevant payment brand.

Answering the SAQ Questions

The PCI Self-Assessment Questionnaire has four options for each question. You can select only one response for each. Here are the responses and when you can use it.

• Yes: You meet the stated requirement and have tested controls.
• Yes with CCW: You meet the requirement using compensating controls; include the Compensating Control Worksheet.
• No: You do not currently meet the requirement or are still implementing a solution.
• N/A: Not applicable to your environment (document why in Appendix C of the SAQ).
