Types of Audit Opinion: Qualified, Adverse and Disclaimer under SA 705

Updated 11 October 2026 · Fact-checked

An auditor gives an unmodified opinion when the financial statements are free from material misstatement. Otherwise SA 705 (Revised) requires a modified opinion: qualified, adverse or disclaimer. The choice depends on the nature of the matter (misstatement or inability to get evidence) and whether its effects are material but not pervasive, or material and pervasive.

Understand Types of Audit Opinion

An audit opinion is the auditor's conclusion on whether the financial statements give a true and fair view under the applicable reporting framework. SA 700 (Revised) says that if the financial statements as a whole are not free from material misstatement, or the auditor cannot obtain sufficient appropriate audit evidence to conclude that they are, the opinion must be modified under SA 705 (Revised).

There are four types. An unmodified opinion means no modification is needed. The other three are modified opinions: a qualified opinion, an adverse opinion and a disclaimer of opinion.

SA 705 says the choice rests on two questions. First, what is the nature of the matter? Either the financial statements are materially misstated, or the auditor is unable to get sufficient appropriate evidence and they may be materially misstated. Second, how pervasive are the effects or possible effects on the financial statements, in the auditor's judgment?

Put the two questions in a grid. Material but not pervasive misstatement: qualified. Material and pervasive misstatement: adverse. Material but not pervasive inability to get evidence: qualified. Material and pervasive inability: disclaimer.

A material misstatement can arise from the appropriateness of the accounting policies chosen, their application, or the appropriateness or adequacy of disclosures. Remember that an Emphasis of Matter paragraph is not a modification. It does not change the opinion.

Key rules to remember

Qualified opinion: Material but not pervasive misstatement, or possible effects of undetected misstatements material but not pervasive → "except for" opinion; The rest of the financial statements are fine. The report carries a Basis for Qualified Opinion section.
Adverse opinion: Material AND pervasive misstatement → financial statements do not give a true and fair view; Expressed when the auditor concludes, on the evidence obtained, that the misstatements are material and pervasive. It does not depend on whether management agrees or disagrees.
Disclaimer of opinion: Unable to obtain sufficient appropriate evidence + possible effects material AND pervasive → no opinion expressed; Also used in extremely rare cases of multiple uncertainties where, despite evidence on each, no opinion can be formed because of their possible cumulative interaction.
Decision grid (SA 705, Para A1): Nature of matter × Pervasiveness → type of opinion; Misstated: material → qualified; pervasive → adverse. Evidence unavailable: material → qualified; pervasive → disclaimer.
No contradiction rule: Adverse or disclaimer on the whole → no unmodified opinion on a single statement or element under the same framework; Such an unmodified opinion would contradict the adverse opinion or disclaimer. Exceptions in A16: unmodified under one framework and adverse under a different framework; disclaimer on results and cash flows with an unmodified opinion on financial position (opening balances, SA 510).
Duty to modify (SA 700, Para 17): Not free from material misstatement OR unable to get sufficient appropriate evidence → modify under SA 705; Modification is mandatory, not optional.

How to solve Types of Audit Opinion questions

Use the same sequence for any case-based question on the type of opinion. Write the reasoning, not just the label.

1Read the facts and identify the matter. State it in one line.
2Decide its nature: is it a misstatement (policy, application or disclosure) or an inability to obtain sufficient appropriate evidence?
3Judge materiality. If the matter is not material, no modification is needed.
4Judge pervasiveness: does it affect only specific elements, or is it fundamental to users' understanding of the financial statements as a whole?
5Match to the grid: misstatement material → qualified; misstatement pervasive → adverse; evidence limitation material → qualified; evidence limitation pervasive → disclaimer.
6Name the type of opinion and quote the standard (SA 705 (Revised); SA 700 (Revised) Para 17 for the duty to modify).
7Add the reporting consequence: a Basis for Modification section, and the wording of the opinion section.
8Check for contradictions, for example no unmodified opinion on a part if you give an adverse opinion or disclaimer on the whole under the same framework.

Quickest way: Two-question grid

When to use it: When time is short and the facts are clearly stated in a case.

Ask: wrong or unknown? Wrong means misstatement. Unknown means evidence limitation.
Ask: limited or everywhere? Limited means material only. Everywhere means pervasive.
Wrong + limited = qualified. Wrong + everywhere = adverse.
Unknown + limited = qualified. Unknown + everywhere = disclaimer.
Write one line of reasoning using the words material and pervasive.

Common mistakes in Types of Audit Opinion

Treating qualified, adverse and disclaimer as degrees of the same thing without linking them to the nature of the matter.
Students memorise a severity ladder and skip the misstatement versus evidence distinction.
Fix: Always state the nature first. Adverse comes only from misstatement. Disclaimer comes only from inability to get evidence (or the rare multiple-uncertainties case).
Giving a disclaimer because the client is uncooperative on a small item.
Students link any limitation with disclaimer.
Fix: A disclaimer needs possible effects that are both material and pervasive. If only material, the opinion is qualified.
Calling an Emphasis of Matter paragraph a modified opinion.
Both add extra text to the report.
Fix: A modified opinion changes the opinion. An Emphasis of Matter paragraph draws attention to a properly presented or disclosed matter and leaves the opinion unmodified. It is not a substitute for a key audit matter either.
Qualifying the opinion for a pervasive misstatement.
Students prefer the softer option.
Fix: If the misstatement is material and pervasive, the opinion must be adverse. Judgment on pervasiveness decides the type.
Giving an adverse opinion or disclaimer and also an unmodified opinion on a single item under the same framework.
Students think it is helpful to the reader.
Fix: SA 705 Para 15 prohibits it because it contradicts the opinion on the whole. Remember the A16 exceptions.
Forgetting the Basis for Modification section and just naming the opinion.
Focus on the label, not the report.
Fix: Close the answer by stating that the report must explain the reasons for the modification in a basis section.

Worked examples

Example 1

During the audit of Sundaram Textiles Ltd, the auditor finds that inventory of ₹5 crore was valued at cost although its net realisable value is lower, resulting in an overstatement of ₹1.2 crore. Profit before tax is ₹6 crore, and the rest of the financial statements are properly stated. Management refuses to adjust. What opinion should the auditor express?

Show the solution

Matter: inventory is overstated by ₹1.2 crore, so the accounting policy is wrongly applied.
Nature: a misstatement, because evidence shows the amount is wrong.
Materiality: judge it by the size of the amount against a benchmark such as profit before tax. Reported PBT of ₹6 crore includes the ₹1.2 crore overstatement. So ₹1.2 crore ÷ ₹6 crore = 20% of reported PBT. Corrected PBT is ₹6 crore − ₹1.2 crore = ₹4.8 crore, and ₹1.2 crore ÷ ₹4.8 crore = 25% of corrected PBT. On either basis the amount is clearly material. Management's refusal does not change materiality. It only means the misstatement stays uncorrected, so the auditor must consider the effect on the opinion.
Pervasiveness: judge it by the effect on the financial statements as a whole, not by the size of the amount alone. The overstatement is material, as shown above. But the error is confined to one element, inventory, and the rest of the financial statements are properly stated. Nothing in the facts shows it is fundamental to users' understanding of the financial statements. So it is not pervasive.
Grid: misstatement, material but not pervasive, means a qualified opinion.
Reporting: use an "except for" opinion and a Basis for Qualified Opinion section describing the ₹1.2 crore overstatement.

Answer: A qualified opinion (except for the inventory overstatement of ₹1.2 crore), with a Basis for Qualified Opinion section, under SA 705 (Revised).

Example 2

Bharat Agro Ltd's management does not let the auditor access the books and records of its main subsidiary, which makes up most of the consolidated assets and revenue. The auditor cannot perform alternative procedures. What opinion should the auditor express, and how does it differ from an adverse opinion?

Show the solution

Matter: the auditor is denied access to records of the major subsidiary.
Nature: an inability to obtain sufficient appropriate audit evidence, not a known misstatement.
Materiality: the subsidiary is the major part of the group, so possible effects are material.
Pervasiveness: effects on consolidated assets and revenue are so large that possible misstatements would be pervasive.
Grid: inability to get evidence, material and pervasive, means a disclaimer of opinion.
Difference: an adverse opinion says the statements are materially and pervasively misstated, on the basis of evidence. A disclaimer says the auditor could not obtain evidence and so gives no opinion.
Reporting: include a basis section explaining the limitation, and do not express an unmodified opinion on any single element under the same framework (SA 705 Para 15).

Answer: A disclaimer of opinion, because the evidence limitation has material and pervasive possible effects. It differs from an adverse opinion, which arises from known pervasive misstatement.

Exam tips

Always give the two-factor reasoning, nature of the matter and pervasiveness. Marks are given for analysis, not only for the label.
Use the exact words "material", "pervasive" and "sufficient appropriate audit evidence" in your answer.
In a distinction question, compare on basis (misstatement or evidence limitation), pervasiveness, wording of the opinion and the auditor's position.
Mention SA 705 (Revised) for modified opinions and SA 700 (Revised) Para 17 for the duty to modify. Do not quote paragraph numbers you are unsure of.
Close case answers with the practical point: the Basis for Modification section in the report and the discussion with those charged with governance.

Types of Audit Opinion: frequently asked questions

What is the difference between a qualified opinion and an adverse opinion?

Both arise from material misstatement. A qualified opinion applies when the effect is material but not pervasive, so the statements are fair except for the matter. An adverse opinion applies when the effect is material and pervasive, so the statements do not give a true and fair view.

What is the difference between an adverse opinion and a disclaimer of opinion?

An adverse opinion follows from evidence that the financial statements are materially and pervasively misstated. A disclaimer follows when the auditor cannot get sufficient appropriate evidence and the possible effects are material and pervasive. In a disclaimer the auditor expresses no opinion.

Can an auditor give a qualified opinion for a scope limitation?

Yes. If the inability to obtain sufficient appropriate audit evidence has possible effects that are material but not pervasive, the opinion is qualified. It is a disclaimer only when the possible effects are also pervasive.

Is an Emphasis of Matter paragraph a modified opinion?

No. It draws attention to a matter already presented or disclosed in the financial statements and does not change the opinion. A modified opinion is qualified, adverse or a disclaimer under SA 705 (Revised).
