The Finance Ministry launched Monday the second edition of tax reform, aiming to improve the capacity of tax officials and integrate taxpayer data.
"There are two highly crucial things: human resources and supporting system, including the information system," Finance Minister Sri Mulyani Indrawati said.
"The hardest thing to reform is manpower, so that it can be an agent of change," she added.
The first edition of tax reform was launched in 2006, aiming to cleanse the previously corrupt tax office.
In 2005, tax revenue amounted to Rp 298.3 trillion (US$29.8 billion), but tax revenue jumped to Rp 571.1 trillion last year, said Darmin Nasution, the tax office chief.
