Basically, tax audits are different from other audits in which the company will assign an internal or external audit team to examine its finances and operations.
This is because the tax audit is not carried out at the request of the organization or company, but rather as a tax authority.
In addition, tax audits do not need to be carried out by every taxpayer because the DGT will determine who needs to be examined based on the risk selection system.
Taxpayers who are found to have indications of discrepancies in the Tax Report cannot refuse a tax audit conducted by the DGT, as this is mandatory.

The HBW suspect is suspected of having issued tax invoices that were not based on actual transactions from January 2018 to May 2019.
Due to the possibility of finding discrepancies in PT BPE's tax reports, such as fictitious tax invoices, HBW finally fulfilled the DJP investigator's call to hand over the suspect's responsibility and Phase II evidence.
In this case, the suspect of HBW violates Article 39A letter A which reads “Any person who deliberately issues fictitious tax invoices can be punished”.
Next is Article 43 paragraph (1) which reads:
- Threat of punishment: minimum 2 years and maximum 6 years in prison
- Fines: 2 to 6 times the tax amount of the fictitious tax invoice
