Treasury reveals gains to workers under Coalition's tax plan

Treasury officials have revealed the annual gains to workers from the Turnbull government’s $140 billion income tax plan in a move that escalates the political dispute over the scale of the benefits going to wealthier households.

The move came after weeks of Labor pressure on the government to disclose the relative benefits to different workers from the sweeping tax cuts over seven years, a central issue in the fairness debate over the reforms.

The documents show that a worker on $80,000 a year currently pays $19,147 in tax and would receive a tax cut worth $540 a year by the end of the seven-year plan.

A worker on $200,000 a year pays $67,232 in tax and would receive a tax cut worth $7225 a year by the end of the changes.

Treasury secretary John Fraser released the details at a Senate estimates hearing on Tuesday morning, providing more fuel for the political debate over the fairness of the changes.
