Around 30 former Bell Pottinger partners who were paid net of tax are facing huge tax liabilities.
One source said the tax collected by the firm was not held in a separate escrow account but “frittered away”, but the Revenue will still demand the tax from the partners.
It is understood that partners found out their tax liability on Friday, with amounts due ranging from £25,000 to as much as £100,000.
Many also borrowed to invest in now-worthless equity in the business.
A source said: “I think anybody can see why staff are livid, especially partners who’ve lost their entire investment and face this tax liability.”
