I would say go self assessment,ie file your own tax return at the end of the year or get an accountant to do it and pay him a one off fee or certainly smaller fees then if you had a company.you can get hms or irish revenue to send you the required forms.Then Fill them in before the specified deadline.
I thought about this setting up a company lark and to be honest its way way over priced.hundreds per month.Also accountants charge huge fees plus vat if you set up a company under them.
