Materiality is the threshold below which misstatements are considered immaterial, too small to matter to a reasonable user of the financial statements. The number drives how much testing happens and which findings make it into the audit report.

Auditors apply benchmarks: 5% of profit before tax for profit-driven entities, 1% of revenue for revenue-driven entities, 1-2% of equity or total assets for asset-heavy entities. The benchmark depends on the most relevant measure to users.
The percentage applied is judgement-based. Higher risk environments (first-year audits, complex transactions, regulatory scrutiny) get lower percentages, more conservative. Standard SME audits typically use 5% of profit or 0.5-1% of revenue.
Performance materiality
Performance materiality is a smaller threshold (usually 50-75% of materiality) used when designing audit procedures. It exists to provide a buffer, multiple small misstatements below materiality could aggregate to something material if not caught individually.
Auditors adjust performance materiality during the audit if conditions change, a significant control deficiency might lower it, a clean prior year might allow it higher. The adjustment drives the sample sizes for each procedure.
Qualitative materiality
Some misstatements are material regardless of size, fraud, related party transactions not disclosed, regulatory non-compliance, items affecting management compensation, or items changing reported losses to profits or vice versa.
Auditors flag qualitative findings prominently in the management letter even where the financial impact is small. The management letter often surfaces these as 'control observations' or 'communications under ISA 260.'
What this means for management
Items below materiality usually do not need adjustment in the financial statements, the auditor signs off without recording them. Items above materiality must be corrected or the auditor qualifies the opinion.
Track misstatements through the year, even small ones. At year-end, the cumulative effect may push individually-immaterial items above the threshold. A monthly close with documented adjustments prevents the year-end cliff.
