JAKARTA (REUTERS) - Indonesia's tax chief resigned on Tuesday (Dec 1) after failing to achieve President Joko Widodo's ambitious tax target this year, media reported quoting the finance minister.

Sigit Priadi Pramudito submitted his letter of resignation and "will not be active" from Wednesday (Dec 2), Finance Minister Bambang Brodjonegoro was quoted as saying by website Detik.com.

Southeast Asia's largest economy is facing a potential budget crisis as its deficit drifts towards its legal limit with government revenue failing to meet expectations.

Tax collection, excluding oil and gas receipts, reached 806 trillion rupiah (S$83 billion) as of Nov 27, representing just 65 per cent of this year's target, media reported.

When the Indonesian government set its tax targets for this year, many analysts said they were unrealistically high. A slowdown in Southeast Asia's largest economy has increased the difficulties officials face in meeting 2015 collection targets.
