The Treasury is today releasing the CAPITA model to the public to allow more people to contribute rigorous, evidence-based policy analysis to Australia’s public policy debate.

CAPITA, a general-purpose model of Australia’s personal income tax and transfer system, is a key tool used by government to analyse the impact of policy reforms on households.

A paper describing the CAPITA model is available on the Treasury Research Institute website.

Today’s release of CAPITA provides public access to the model. Users of the model will require access to the Australian Bureau of Statistics data underpinning it and must comply with the CAPITA user licence agreement.

“We encourage users of the model to share any suggested improvements to progress the development of CAPITA into the future through the CAPITA user group. Users of the model can contact Treasury at [email protected],” the Treasury said in a press statement.

CAPITA was developed jointly by the Treasury, the Department of Social Services and the Department of Employment, with assistance from the Australian Bureau of Statistics and the Parliamentary Budget Office.

Interested users can obtain a copy of CAPITA by following the relevant links on the Treasury website.
