Prior to tax audit, we review and analyse key tax compliance documents such as tax returns and part of accounting documents. A taxpayer can then identify tax audit risks. If the taxpayer undertakes measures to mitigate these risks in advance, the taxpayer could reduce additional tax payment caused by tax audit as well as resources to be dedicated to tax audit, such as extensive discission with tax auditors.
In addition, these days the National Tax Agency(NTA) ’s focus is not only additional tax amount, but the NTA also takes a risk-based approach which assesses the governance standards of each taxpayer. The risk-based approach differentiates the frequency of tax audit. If a taxpayer enhances tax governance prior to tax audit, good tax governance will help to reduce the frequency of next tax audits.
