Types of Audit Opinions: Unmodified and Modified (SA 705)

Updated 4 October 2026 · Fact-checked

An auditor gives an unmodified opinion when the financial statements are prepared fairly in all material respects. Otherwise the opinion is modified. Decide two things: is the matter material, and is it a misstatement or an inability to get evidence? Then pick qualified, adverse or disclaimer.

Understand Types of Audit Opinions: Unmodified and Modified (SA 705)

The auditor's opinion tells users whether the financial statements give a true and fair view (or are presented fairly) in all material respects under the applicable framework. If they do, the auditor gives an unmodified opinion. SA 705 (Revised) deals with the cases where the opinion has to be modified.

An opinion is modified in two situations. First, the auditor concludes, based on evidence, that the financial statements are materially misstated. Second, the auditor cannot obtain sufficient appropriate audit evidence to conclude that they are free from material misstatement. Keep these two causes apart. They drive the whole topic.

There are three modified opinions. A qualified opinion says the financial statements are fine except for one matter. An adverse opinion says the financial statements are misleading as a whole. A disclaimer of opinion says the auditor does not express any opinion at all.

Two tests decide the type. The first is materiality: if the matter is not material, there is no modification. The second is pervasiveness: do the effects spread across many items, affect a substantial part of the financial statements, or relate to disclosures fundamental to users' understanding? Material but not pervasive leads to a qualified opinion. Material and pervasive leads to an adverse opinion (for misstatement) or a disclaimer (for inability to get evidence).

If the auditor cannot get evidence and the possible effects could be both material and pervasive, the auditor disclaims. There is also a separate, extremely rare case. In extremely rare circumstances involving multiple uncertainties, the auditor disclaims when, despite having obtained sufficient appropriate audit evidence on each uncertainty, it is not possible to form an opinion because of the potential interaction and possible cumulative effect of the uncertainties.

Key rules to remember

Qualified opinion: misstatement: Material misstatement + not pervasive → Qualified ('except for'); Wording: 'except for the effects of the matter described in the Basis for Qualified Opinion section'.
Adverse opinion: Material misstatement + pervasive → Adverse; States that the financial statements do not give a true and fair view.
Qualified opinion: inability to get evidence: Cannot get evidence + possible effects material but not pervasive → Qualified ('except for'); Wording: 'except for the possible effects of'.
Disclaimer of opinion: Cannot get evidence + possible effects material and pervasive → Disclaimer; Auditor says: 'we do not express an opinion'. A disclaimer is also required in extremely rare circumstances involving multiple uncertainties, where, despite sufficient appropriate evidence on each uncertainty, it is not possible to form an opinion because of their potential interaction and possible cumulative effect.
Decision matrix: Cause (misstatement / no evidence) × Extent (material / pervasive); Misstatement: qualified or adverse. No evidence: qualified or disclaimer. Adverse is never used for lack of evidence.
Basis for Opinion heading: Qualified / Adverse: 'Basis for Qualified (Adverse) Opinion'. Disclaimer: 'Basis for Disclaimer of Opinion'; The basis paragraph comes after the opinion paragraph and explains the reason and, where practicable, quantifies the effect.

How to solve Types of Audit Opinions: Unmodified and Modified (SA 705) questions

Use this sequence for any case-based question on SA 705.

1Read the facts and find the issue: a wrong accounting treatment, a disclosure gap, or a limit on the audit work (e.g., could not attend stock count, records unavailable).
2Classify the cause: material misstatement (auditor disagrees with management) or inability to obtain evidence (scope limitation).
3Test materiality using the amount against profit, total assets or revenue, and the nature of the item.
4Test pervasiveness: does it affect many items, a substantial part of the statements, or fundamental disclosures?
5Pick the opinion using the matrix: misstatement gives qualified or adverse; no evidence gives qualified or disclaimer.
6Write the opinion in the right words: 'except for' for qualified, 'do not give a true and fair view' for adverse, 'we do not express an opinion' for disclaimer.
7Add the Basis for Opinion paragraph with the reason and the quantified effect. Where the effect cannot be quantified, say so.
8Conclude in one line, e.g., 'Hence the auditor should issue a qualified opinion.'

Quickest way: Two-question shortcut for MCQs and written answers

When to use it: Use it when the time is short, for MCQs and for the first line of a written answer.

Ask: misstatement or no evidence? Write M or E next to the question.
Ask: is it pervasive? If the facts say 'material' only, assume not pervasive.
M and not pervasive: qualified. M and pervasive: adverse.
E and not pervasive: qualified. E and pervasive: disclaimer.
In MCQs, eliminate 'adverse' whenever the problem is a scope limitation, and eliminate 'disclaimer' whenever evidence was obtained but the treatment is wrong.
In written answers, use this layout: Issue, Provision of SA 705, Application to the facts, Conclusion. Each part earns step marks.

Common mistakes in Types of Audit Opinions: Unmodified and Modified (SA 705)

Giving an adverse opinion for a scope limitation.
Students link 'serious problem' with 'adverse'.
Fix: Adverse is only for material and pervasive misstatement. For pervasive lack of evidence, the answer is a disclaimer.
Giving a disclaimer when the auditor simply disagrees with an accounting treatment.
Students mix up 'not agreeing' with 'not able to conclude'.
Fix: If the auditor has evidence and finds the statements wrong, it is a misstatement. Choose qualified or adverse.
Modifying the opinion for an immaterial item.
Students treat every error as a reason to qualify.
Fix: Always test materiality first. No material effect means an unmodified opinion, though the auditor may report the point to management.
Ignoring pervasiveness and stopping at 'material'.
Students remember only one test.
Fix: Apply both tests. Materiality decides whether to modify; pervasiveness decides how severely.
Using the wrong wording, such as 'except for' in an adverse opinion.
Students memorise the types but not the phrases.
Fix: Learn: qualified = 'except for'; adverse = 'do not give a true and fair view'; disclaimer = 'we do not express an opinion'.
Forgetting the Basis for Opinion paragraph.
Students focus only on the opinion paragraph.
Fix: Always state the reason and, where practicable, quantify the effect in a Basis paragraph with the matching heading.

Worked examples

Example 1

During the audit of Alpha Ltd, the auditor finds that a trade receivable of ₹8,00,000 is clearly irrecoverable, but management refuses to provide for it. Profit before tax is ₹1,20,00,000 and total assets are ₹15,00,00,000. Management has no other disagreements. What opinion should the auditor give?

Show the solution

Cause: the auditor has evidence and disagrees with management's treatment, so this is a misstatement.
Materiality: ₹8,00,000 is about 6.7% of profit before tax (8,00,000 ÷ 1,20,00,000), which is reasonably significant, so assume it is material.
Pervasiveness: it affects one item (receivables) and the related profit figure. It is not spread across many items and does not affect fundamental disclosures, so it is not pervasive.
Apply the matrix: material misstatement and not pervasive gives a qualified opinion.
Wording: 'In our opinion, except for the effect of the matter described in the Basis for Qualified Opinion section, the financial statements give a true and fair view...'. The Basis paragraph states that no provision of ₹8,00,000 was made, so receivables and profit are overstated by ₹8,00,000.

Answer: A qualified opinion ('except for'), with a Basis for Qualified Opinion paragraph quantifying the ₹8,00,000 overstatement.

Example 2

Beta Ltd's auditor was appointed after year end and could not attend the physical verification of inventory. Inventory is the major asset, and no alternative procedures can give sufficient evidence. The auditor also could not verify other key areas because the accounting records were largely destroyed in a fire. What opinion should the auditor give?

Show the solution

Cause: the auditor could not get sufficient appropriate evidence, so this is an inability to obtain evidence, not a misstatement.
Materiality: inventory is the major asset, so the possible effects are material.
Pervasiveness: records are largely destroyed and other key areas are also unverifiable, so the possible effects are widespread and substantial. They are pervasive.
Apply the matrix: evidence not obtained and possible effects material and pervasive gives a disclaimer of opinion.
Wording: 'We do not express an opinion on the accompanying financial statements... Because of the significance of the matters described in the Basis for Disclaimer of Opinion section, we have not been able to obtain sufficient appropriate audit evidence to provide a basis for an audit opinion.'
Do not give an adverse opinion, because the issue is lack of evidence, not a known misstatement.

Answer: A disclaimer of opinion, with a Basis for Disclaimer of Opinion paragraph explaining the inventory and records limitations.

Exam tips

In case studies, underline the cause words: 'refused to provide', 'wrongly capitalised' point to misstatement; 'could not verify', 'records not available' point to scope limitation.
Write the type of opinion in the first line of your answer, then justify it. Examiners award marks for the correct conclusion and for the reasoning.
Quote the key phrase: 'except for', 'do not give a true and fair view', or 'we do not express an opinion'. These are often tested in MCQs.
Practise the ICAI RTP and MTP questions on this topic. They usually give a mix of facts and ask which of the three modified opinions applies.
Link SA 705 with SA 706 and SA 701 for comparison questions: modification changes the opinion, while emphasis and other matter paragraphs do not.

Types of Audit Opinions: Unmodified and Modified (SA 705): frequently asked questions

What is the difference between qualified, adverse and disclaimer of opinion?

A qualified opinion says the statements are fair except for one material matter that is not pervasive. An adverse opinion says the statements are materially and pervasively misstated. A disclaimer says the auditor could not obtain enough evidence, with possible pervasive effects, and so gives no opinion.

When does the auditor give a disclaimer of opinion?

When the auditor cannot obtain sufficient appropriate audit evidence and the possible effects of undetected misstatements could be both material and pervasive. In extremely rare circumstances involving multiple uncertainties, the auditor also disclaims when, despite sufficient appropriate evidence on each uncertainty, it is not possible to form an opinion because of their potential interaction and possible cumulative effect.

Can an auditor give an adverse opinion for lack of evidence?

No. Adverse is used only when the auditor has concluded that the financial statements are materially and pervasively misstated. If the problem is lack of evidence, the choice is qualified or disclaimer.

Does a modified opinion mean the auditor found fraud?

No. A modified opinion only means there is a material misstatement or a limitation on the audit evidence. The cause could be an error, a disagreement on accounting policy, or a scope limit. Fraud, if found, is dealt with under separate reporting requirements.
