Details yet to emerge on how new supermarket tax will be administered
The Scottish Retail Consortium (SRC) claim the Scottish Government has so far failed to answer key questions from business organisations about the proposed supermarket tax.
SRC says since the new tax was first announced in the Draft Budget last week it is still unclear which companies will be affected and how the tax will be assessed and calculated.
The proposed supermarket tax is estimated will push business rates up by 35 per cent for large high street stores and out-of-town retail parks.
Major retailers of alcohol and tobacco in Scotland will pay around s110 million in tax over the next three years under the terms of the new levy, tabled to launch in the spring of 2012.
CBI Scotland, the Scottish Chambers of Commerce, SRC and the Wine and Spirit Trade Association have collectively written to finance secretary John Swinney to condemn the tax and the lack of consultation before the budget announcement.
SRC director, Ian Shearer, said Rural Affairs Secretary, Richard Lockhead, who met with the Scottish Grocery Retailers' Forum on Wednesday, had faced "the impossible task of defending an illogical measure".
Shearer said: "This type of policy making sends out a dangerous message to businesses of all kinds about Scotland as a place to invest.
"The Scottish Government and the retail sector have many goals in common.
"We both want to see growth, investment and job creation. But instead of partnership, ministers have opted for an ill-conceived and discriminatory tax.
"This is no way to treat a sector that provides around one in ten jobs in Scotland.
"Instead of being able to focus on the future success of their businesses, retailers are left trying to find out how much damage has been done by this Governments tax raid."
Finance Minister, John Swinney, is due to meet with the SRC in late October.
The new supermarket tax was a surprise announcement in the Draft Budget last week.
It follows a failed proposal from the last parliament to introduce a s30 million 'Scottish Large Retailer Levy' on stores with a rateable value over s750,000.
The so-called 'Tesco tax' was voted down in the Scottish Parliament last February and was not included the SNPs election manifesto.
