Audit Evidence and Forming an Opinion on Financial Statements

Updated 11 October 2026 · Fact-checked

Forming an opinion means the auditor concludes whether reasonable assurance has been obtained that the financial statements as a whole are free from material misstatement. SA 700 (Revised) says this conclusion rests on audit evidence, uncorrected misstatements and evaluations of policies, estimates, disclosures and fair presentation. If not, the opinion is modified under SA 705.

Understand Audit Evidence and Forming an Opinion

An auditor does not give a guarantee. The auditor gives reasonable assurance that the financial statements as a whole are free from material misstatement, whether due to fraud or error. The opinion is the end point of the audit. Everything before it, such as risk assessment, procedures and evidence, feeds into it.

Audit evidence is the information the auditor uses to reach conclusions. Its quality is judged on two tests. Sufficient is about quantity: is there enough? Appropriate is about quality: is it relevant and reliable? Better quality reduces the quantity needed, but a large amount of poor evidence does not make up for poor quality.

Under SA 700 (Revised), para 11, the auditor's conclusion takes into account three things: (a) the conclusion under SA 330 on whether sufficient appropriate audit evidence has been obtained; (b) the conclusion under SA 450 on whether uncorrected misstatements are material, individually or in aggregate; and (c) the evaluations required by paragraphs 12 to 15.

Those evaluations (para 13) cover whether significant accounting policies are adequately disclosed, whether policies are consistent with the framework and appropriate, whether management's estimates are reasonable, whether information is relevant, reliable, comparable and understandable, whether disclosures let users understand the effect of material transactions, and whether terminology and statement titles are appropriate. Para 15 adds that the framework must be adequately referred to or described.

For a fair presentation framework, para 14 adds a further test: the overall presentation, structure and content, and whether the statements with notes represent the underlying transactions and events fairly. If the auditor finds material misstatement, or cannot get sufficient appropriate evidence, the opinion must be modified under SA 705 (Revised) (para 17).

Key rules to remember

Basis of the opinion (SA 700, para 11): Opinion = conclusion on (a) sufficient appropriate evidence (SA 330) + (b) materiality of uncorrected misstatements (SA 450) + (c) evaluations in paras 12–15; Write all three limbs. Missing the misstatement limb is a common loss of marks.
Sufficient appropriate evidence: Sufficiency = quantity; Appropriateness = relevance + reliability; Higher risk of misstatement needs more evidence. Poor quality cannot be cured by more quantity.
Fair presentation evaluation (para 14): (a) overall presentation, structure and content; (b) statements and notes represent underlying transactions and events fairly; Applies only to a fair presentation framework.
Compliance framework (para 19): No duty to evaluate fair presentation; if statements are misleading in extremely rare cases, discuss with management and decide whether and how to communicate; Do not apply the para 14 test here.
Modification trigger (para 17): Statements not free from material misstatement OR unable to obtain sufficient appropriate evidence → modify opinion per SA 705 (Revised); Two triggers: misstatement and scope limitation.
Equivalent phrases (A19): "present fairly, in all material respects" = "give a true and fair view"; The wording used follows law or practice in the jurisdiction.

How to solve Audit Evidence and Forming an Opinion questions

Use this order for any case question on evidence and opinion. It follows the structure of SA 700 para 11.

1Identify the framework: fair presentation or compliance. This decides whether the para 14 test applies.
2Test the evidence: is it sufficient (enough) and appropriate (relevant and reliable)? Note any area where evidence is missing.
3List misstatements found. Decide if each is material, and whether they are material in aggregate once uncorrected ones are added up.
4Evaluate para 13 items: policies, estimates, disclosures, comparability, terminology. Add para 15 on the framework description.
5For a fair presentation framework, assess overall presentation, structure and content, and whether transactions are fairly represented.
6Conclude: if there is material misstatement or insufficient evidence, modify under SA 705. Otherwise, an unmodified opinion.
7State the conclusion in the format: provision, application to the facts, conclusion.

Quickest way: Three-limb check

When to use it: Use when time is short and the question asks whether the auditor can give a clean opinion.

Evidence: enough and reliable? If no, scope limitation.
Misstatements: material alone or together and uncorrected? If yes, modify.
Evaluations: policies, estimates, disclosures, fair presentation OK? If no, modify.
If all three pass, unmodified opinion. Cite SA 700 paras 11 and 17 and SA 705.

Common mistakes in Audit Evidence and Forming an Opinion

Saying the auditor gives absolute assurance that the statements are correct.
Students confuse the opinion with a certificate of accuracy.
Fix: Always use the words reasonable assurance and as a whole, free from material misstatement.
Treating sufficient and appropriate as the same thing.
The two words sound similar.
Fix: Define sufficient as quantity and appropriate as quality, covering relevance and reliability.
Judging misstatements one by one and ignoring aggregation.
Each item looks small by itself.
Fix: Para 11(b) says individually or in aggregate. Add up uncorrected misstatements before concluding.
Applying the fair presentation test to a compliance framework.
Students remember para 14 but not para 19.
Fix: Check the framework first. For a compliance framework, no fair presentation evaluation is required.
Forgetting that lack of evidence also forces a modified opinion.
Students link modification only to errors found.
Fix: Remember both triggers in para 17: material misstatement and inability to obtain sufficient appropriate evidence.
Thinking true and fair view and present fairly are different tests.
The wording differs.
Fix: A19 says they are regarded as equivalent. The law of the jurisdiction decides which phrase is used.

Worked examples

Example 1

During the audit of Kaveri Textiles Ltd, the auditor finds uncorrected misstatements: inventory overstated by ₹4,00,000 and expenses understated by ₹3,00,000. Management refuses to correct either. The auditor's materiality is ₹5,00,000. Can the auditor conclude the statements are free from material misstatement?

Show the solution

Provision: SA 700 (Revised) para 11(b) requires the auditor to consider whether uncorrected misstatements are material, individually or in aggregate, as concluded under SA 450.
Individually, ₹4,00,000 and ₹3,00,000 are each below ₹5,00,000.
Aggregate effect: both items overstate profit. Inventory overstated by ₹4,00,000 raises profit; expenses understated by ₹3,00,000 raises profit. Total effect is ₹4,00,000 + ₹3,00,000 = ₹7,00,000.
₹7,00,000 exceeds ₹5,00,000, so the misstatements are material in aggregate.
Under para 17(a), the statements as a whole are not free from material misstatement, so the opinion must be modified under SA 705 (Revised).

Answer: No. Each item is below materiality, but together they overstate profit by ₹7,00,000, which exceeds ₹5,00,000. The auditor must modify the opinion under SA 705 (Revised).

Example 2

Explain what the auditor must evaluate under SA 700 (Revised) before forming an opinion on statements prepared under a fair presentation framework.

Show the solution

Start with the objective: the auditor must conclude whether reasonable assurance is obtained that the statements as a whole are free from material misstatement, due to fraud or error (para 11).
State the three inputs: the SA 330 conclusion on sufficient appropriate evidence, the SA 450 conclusion on uncorrected misstatements, and the evaluations in paras 12 to 15.
List para 13 evaluations: disclosure of significant policies; policies consistent with the framework and appropriate; reasonableness of estimates; information being relevant, reliable, comparable and understandable; adequate disclosures to understand material transactions; appropriate terminology and titles.
Add para 15: adequate reference to or description of the applicable framework.
Add para 14 for a fair presentation framework: overall presentation, structure and content, and whether the statements with notes represent underlying transactions and events fairly.
Conclude: if the statements are not free from material misstatement, or evidence is insufficient, the opinion is modified under SA 705 (Revised) (para 17).

Answer: The auditor evaluates the evidence, uncorrected misstatements, the para 13 and para 15 matters and, for a fair presentation framework, the para 14 fair presentation test. A failure on misstatement or evidence leads to a modified opinion under SA 705.

Exam tips

Structure answers as provision, facts, conclusion. Quote SA 700 para 11 early.
In numerical cases, always show the aggregate of misstatements against materiality.
Name the framework type before applying paras 14 or 19.
Mention both modification triggers from para 17.
If the case mentions missing records or refusal of access, think scope limitation and insufficient evidence.

CA FinalSA 700 (Revised): Forming an Opinion on Financial Statements

Audit Evidence and Forming an Opinion: frequently asked questions

What does sufficient appropriate audit evidence mean?

Sufficient measures the quantity of evidence. Appropriate measures its quality, meaning relevance and reliability. The auditor needs both to support the opinion.

How does an auditor form an opinion on financial statements?

The auditor concludes whether reasonable assurance has been obtained that the statements are free from material misstatement. This considers the evidence, uncorrected misstatements and the evaluations in SA 700 paras 12 to 15. If the conclusion is negative, the opinion is modified.

Are true and fair view and present fairly different?

No. SA 700 A19 regards them as equivalent. The law or practice of the jurisdiction decides which phrase is used.

When must the auditor modify the opinion?

When the statements as a whole are not free from material misstatement, or when the auditor cannot obtain sufficient appropriate evidence to conclude that they are. SA 705 (Revised) then applies.
