JAKARTA (Nov 21): Indonesia will review its tax treaties with dozens of countries and may suspend those it concludes are being abused for tax avoidance, as the government looks to significantly boost revenue, the finance minister said on Friday.

President Joko Widodo, who took office last month, believes that Southeast Asia's biggest economy is only collecting half of the taxes it should be and is pressuring tax collectors to do more.

More than half of Indonesia's estimated 60 million tax payers are considered tax evaders, while only 12 percent of companies pay taxes, Finance Minister Bambang Brodjonegoro said.

"We have so many tax treaties. We have to reconsider whether we need them that much," Brodjonegoro told reporters. "A lot of these are not suitable for us as they are used to evade tax payments."

He gave no details about the review, including a timeframe for its completion.

Widodo said on Thursday that Indonesia had the potential to collect 1,200 trillion rupiah ($99 billion) more in annual tax revenue than this year's target.

The government has a tax revenue target of 1,246.1 trillion rupiah, but the finance ministry expects it will likely fall around 7 percent short due to a slower-than-expected economy and limited tax collecting capacity.

The 2015 budget, which was passed by the previous administration, has a tax revenue target of 1,380 trillion rupiah.

Widodo has asked the tax office to exceed that target next year and collect around 1,850 trillion rupiah, but tax officials said that could prove difficult with their limited resources.

The finance ministry aims to recruit 10,000 more tax auditors over the next five years, raising their total from 42,000, Brodjonegoro said. (1 US dollar = 12,175.0000 rupiah)
