Finance Minister Grant Robertson and Revenue Minister Stuart Nash have confirmed that they have received the Tax Working Group's final report - widely expected to recommend a Capital Gains Tax.
But details of the report will stay under wraps until a public release on February 21 and formal response to the proposals from the Government won't be released until April.
"The Final Report will now be analysed by officials, discussed with Coalition and Confidence and Supply partners, and then presented to Cabinet on 18 February," the Government said in a statement this morning.
"The Tax Working Group will hold a media briefing on 21 February to release the Report, and the Government will give any initial responses at this time."
Within the tax industry, it is expected that the report will recommend a broad and comprehensive capital gains tax set at the marginal tax rate with few if any concessions or exemptions - other than the family home.
