TWSA320 Materiality in Planning and Performing an Audit 　　　　

Status

Revised by Auditing Standards Committee in Taiwan on 4 October, 2022

Summary

This Standard deals with the auditor’s responsibility to apply the concept of materiality in planning and performing an audit of financial statements. It explains how materiality is applied in evaluating the effect of identified misstatements on the audit and of uncorrected misstatements, if any, on the financial statements and in forming the opinion in the auditor’s report.

When establishing the overall audit strategy, the auditor shall determine materiality for the financial statements as a whole (and, if applicable, the materiality level or levels for particular classes of transactions, account balances or disclosures). The auditor shall also determine performance materiality for purposes of assessing the risks of material misstatement and determining the nature, timing and extent of further audit procedures. The auditor’s determination of materiality is a matter of professional judgment, and is affected by the auditor’s perception of the financial information needs of users of the financial statements. 　

The auditor shall revise materiality for the financial statements as a whole (and, if applicable, the materiality level or levels for particular classes of transactions, account balances or disclosures) in the event of becoming aware of information during the audit that would have caused the auditor to have determined a different amount (or amounts) initially. If the auditor concludes that a lower materiality for the financial statements as a whole (and, if applicable, materiality level or levels for particular classes of transactions, account balances or disclosures) than that initially determined is appropriate, the auditor shall determine whether it is necessary to revise performance materiality, and whether the nature, timing and extent of the further audit procedures remain appropriate.

Effective date

This Standard is effective from 15 December, 2022.
