BILLIONAIRE mining magnate Clive Palmer's mining company Mineralogy reportedly paid no tax in the 2010-11 financial year.
A Fairfax media report on Thursday cited ASIC documents showing the company had reported losses for the past three years.
Mr Palmer has been a virulent critic of the mining tax proposed by the Federal Government.
A company spokesman would not comment on the figures except to say the magnate had a "vast portfolio of business interests including numerous resource companies".
"Mineralogy lodges its accounts with ASIC and follows all regulatory procedures."
