Southeast Asia's biggest economy this month is winding up one of world's most successful tax amnesties, with at least 745,000 taxpayers declaring more than $330 billion of assets so far.
President Joko Widodo has cited higher tax revenue as the key to boosting infrastructure spending and growth. But if the amnesty is to avoid being just a one-off windfall, Indonesia needs to improve a tax collection ratio well below many of its peers, international agencies and local officials have said.
To that end, Indonesia's finance minister Sri Mulyani Indrawati has set up a special tax reform team to boost collection. It faces an immense task in a country where tens of millions of people - both the wealthy and the poor - remain outside the tax system.
Parliament is considering draft legislation that would overhaul an institution the public views as one of Indonesia's most corrupt, according to global corruption watchdog Transparency International.
"People don't pay taxes because they believe they won't get caught," said Darussalam (like many Indonesians, he goes by one name), a partner at consultancy Danny Darussalam Tax Centre.
