The report from SPICe found that funds for the NHS had been included as local government cash.
The Scottish Government also included £70 million of council tax rises in order to claim funds for local services were rising.
Scottish Conservative shadow finance secretary Murdo Fraser said:
"Dodgy Derek's double counting con has been found out. In short, the Finance Secretary has signed off on the kind of creative accountancy that would make Fred Goodwin blush.
"NHS money has been double counted as cash for local councils. And the SNP has simply banked 3% council tax rises everywhere in Scotland, even though this is for local authorities to decide.
"Incredibly this is happening at a time when - as SPICE confirms - the SNP Budget is rising, thanks to decisions made by the UK Government.
"Yet because of the SNP's incompetence, it is making Scotland the highest taxed part of the United Kingdom whilst still cutting local services.
"Nicola Sturgeon tried to hide these cuts using dodgy figures. This kind of spin and manipulation is a disgrace.
"Ultimately it is the First Minister who has to take responsibility for all this.
"She is the one who replaced 'Honest John' as finance secretary with Dodgy Derek, and it is her government that has shamefully spun these fiddled figures."
