I have read a few Threads here about operating as a Sole Trader, I have recently undertook this particular status, I have been advised to operate on as simple a basis as possible to start with, i.e don't register for VAT until you believe you will exceed €33,700 etc, keep separate bank account for monies etc.. however I wonder do I need to ring up Revenue and inform them I am no longer PAYE and will be operating as a Sole Trader? what does this entail
