FAQ
How can a tax firm help if I face a tax audit?
A tax audit is not simply about submitting documents. Organizing the facts and setting the right response strategy are critical. HAON supports clients not only after receiving an audit notice, but also through pre-audit diagnostics to identify risk factors, organize documentation, build explanatory arguments, and develop issue-specific response strategies.
We help reduce unnecessary misunderstandings and taxation risks during the audit process, enabling clients to respond in a more organized and structured way.
