The Treasury's Role
The Treasury is responsible for forecasting how much tax revenue the government can expect to earn. Twice a year the Treasury publishes Economic and Fiscal Updates which forecast revenue for the following five years.
The Financial Statements of the Government of New Zealand report on revenue that the government has received.
Inland Revenue also forecasts how much the government is likely to receive in revenue in future years. The Budget Economic and Fiscal Update 2017 has tables showing both departments' forecast figures. The Treasury's forecasts are the Crown's official forecasts.
The Treasury provides tax policy advice jointly with the Inland Revenue.
