Paddy, thanks for your reply!
So, I don't need to file the form this year? I guessed I would need to file income / expenditure for this year, at the end of this year.
Is there a website that spells out my situation in absolute laymans terms? I can only ever find more detailed information on vat registered businesses, and it seems to be quite a different process.
Due to the very limited turnover of my business, I really want to try and avoid paying for an accountant if at all possible.
Another question... I'm registered on the Core.ie site. Can I file the B1 online form instead?
