The auditor's documentation of the results of auditing procedures directed at the tax accounts and related disclosures also should include sufficient competent evidential matter about the significant elements of the client's tax liability contingency analysis. This documentation should include copies of the client's documents, schedules, or analyses (or auditor-prepared summaries thereof) to enable the auditor to support his or her conclusions regarding the appropriateness of the client's accounting and disclosure of significant tax-related contingency matters. The audit documentation should reflect the procedures performed and conclusions reached by the auditor and, for significant matters, include the client's documentary support for its financial statement amounts and disclosures.
