James Joseph Daly, of 13 Grays Meadow, Cloghan, is listed as one of 30 cases on Revenue's Tax Defaulters list for the first quarter of the year.
Trading as 'Any Gear', Mr Daly's total relates to over 4.5million euro in unpaid tax, over 2.5m euro in interest and over 4.5m euro in penalties.
It arises from a Revenue investigation into non-declaration of income tax and VAT.
