HASiL tax audit: types of audit, the process and your rights as a taxpayer
Updated: 8 November 2026 Independently fact-checked.
What is a tax audit?
A tax audit is an examination conducted by the Inland Revenue Board of Malaysia (HASiL / LHDNM) to ensure that taxpayers report income and pay tax correctly.
Under the Self-Assessment System (STS), audit is HASiL's main activity to improve voluntary compliance. A taxpayer can be selected for audit at any time — but selection does not mean the taxpayer has committed an offence.

Two types of audit
HASiL conducts two types of audit:
- Desk audit — carried out based on available documents and information, usually at HASiL's office.
- Field audit — involves further examination outside HASiL's office, including visits to the taxpayer's premises if necessary.

Simple example
Mei Ling runs a small business and receives an audit notice letter from HASiL. She does not panic — being selected for audit does not mean she has committed an offence. She prepares the relevant account books and supporting documents, answers the officer's questions, and makes sure only relevant records are requested. She also appoints a registered tax agent to be present during the interview. Throughout the audit period, she gives no gifts to the audit officer.
(Illustrative example to show the concept — not specific tax advice.)
