Finance Secretary John Swinney proposed the setting up of a new tax office to be called Revenue Scotland on 7 June 2012.
It will become responsible for collecting the replacements for stamp duty and landfill duty when the powers are handed to Holyrood in 2015.
Mr Swinney told MSPs it would be 25% cheaper than asking Her Majesty's Revenue and Customs (HMRC) to do the work.
The passage of the
Scotland Act 12
means that from April 2015 the Scottish Parliament will be empowered to collect and manage the current stamp duty and landfill tax.
Mr Swinney launched the consultation for replacing the first of these taxes the Land and Buildings Transaction Tax to replace Stamp Duty Land Tax.
The proposals include changing the structure of the tax to a progressive system where the amount of tax paid is more closely related to the value of the property.
Scottish Labour finance spokesperson Ken Macintosh asked the finance secretary how much setting up Revenue Scotland would cost?
Mr Swinney said in terms of the cost of collection of the two taxes, for HMRC to deliver the status quo the total costs to March 2020 would be £22m.
The equivalent costs including setting up Revenue Scotland and having it collect the taxes until 2020 would be just over £16.6m.
Scottish Conservative finance spokesperson Gavin Brown said "just what we always wanted yet another quango" and he asked where Mr Swinney got the figures for the HMRC estimate from.
Mr Swinney said he thought Mr Brown would welcome the fact the government were taking forward efficiencies which would lead to savings for the public purse.
