THE Turnbull government will prosecute the case for pressure to be increased on multinational companies who fail to pay tax, when G20 finance ministers meet in Washington. 
Assistant Treasurer Kelly O'Dwyer will represent Treasurer Scott Morrison and Finance Minister Mathias Cormann, who are working on the Budget, at the meeting.
Ms O'Dwyer yesterday confirmed she would raise multinational tax issues during the meeting.
"During Australia's time of the chair of G20 we pushed very hard for the need for reform around multinationals," she said.
Australian Taxation Office Commissioner Chris Jordan is leading an international working group aimed at cracking down on tax avoiders.
"Australia is at the forefront of this and will continue to be. For us it's about ensuring the integrity of our taxation base," Ms O'Dwyer said.
"We've got one of the toughest pieces of legislation in the world around multinational anti-avoidance laws." Ms O'Dwyer arrived in Washington last night after spending the first part of the week in New York chairing roundtable meetings with venture capital firms, focusing on innovation and investment.
