SA 220 – Quality Control for Audit of Financial Statements: Scope, Applicability, and Objectives

## SA 220 – Quality Control for Audit of Financial Statements

### What is SA 220?

SA 220 deals with Quality Control specifically at the engagement level for audits of financial statements.

> Key Premise: SA 220 is based on the assumption that the firm is already subject to SQC 1 (firm-level quality control). SA 220 builds on top of SQC 1 at the individual engagement level.

---

### Applicability

SA 220 applies to:

  • Audit engagements
  • Review engagements
  • Assurance engagements
  • Related service engagements

---

### Two Levels of Quality Control

LevelStandardResponsibility
Firm LevelSQC 1Managing Partner
Engagement LevelSA 220Engagement Partner

---

### Objectives of SA 220

To implement quality control procedures at the engagement level so as to:

Objective (a): Ensure the audit complies with:

  • Professional Standards
  • Regulatory Requirements
  • Legal Requirements

Objective (b): Enable the auditor to issue an appropriate audit report.

---

### Engagement Partner's Responsibility for Quality

The Engagement Partner bears overall responsibility for the quality of each audit engagement.

This responsibility emphasises the importance of:

1. Achieving Objective (a) of SA 220 (compliance with standards/law)

2. Achieving Objective (b) of SA 220 (appropriate report)

3. Complying with the Firm's Quality Control Policies & Procedures (under SQC 1)

4. Enabling every engagement team member to raise concerns without fear of reprisals

5. Recognising that quality is essential in performing audit engagements

> Exam Tip: If a question asks about elements of SA 220 not explicitly covered in SA 220 notes, write the corresponding content from SQC 1 — the two standards are complementary.

Worked example

### Example 1

Q: What is the premise/basis on which SA 220 operates?

SA 220 is premised on the basis that the firm is subject to SQC 1 (Standards on Quality Control). SA 220 operates at the engagement level and supplements the firm-level quality controls already established under SQC 1.

### Example 2

Q: State the objectives of SA 220.

SA 220 has two objectives at the engagement level:

(a) To ensure the audit engagement complies with Professional Standards, Regulatory Requirements, and Legal Requirements.

(b) To enable the auditor to issue an appropriate audit report.

Both objectives are implemented through quality control procedures at the engagement level.

### Example 3

Q: Distinguish between the responsibilities under SQC 1 and SA 220.

⚠️ Common exam mistakes

  • Confusing SA 220 (engagement-level) with SQC 1 (firm-level) — they operate at different levels and have different responsible persons.
  • Assuming SA 220 applies only to audit engagements — it also applies to review, assurance, and related service engagements.
  • Attributing overall engagement quality responsibility to the Managing Partner — it is the Engagement Partner who is responsible at the engagement level.
  • Ignoring the premise: SA 220 assumes the firm is already subject to SQC 1; without SQC 1 compliance, SA 220 alone is insufficient.
  • Forgetting the 'no fear of reprisals' element when listing the Engagement Partner's quality responsibilities — this is a frequently tested point.
