Here is the official lin - Citizens Information:
Self-employed & unemployments.
You will be subject to means test.
I was out for 3 months, living on savings and rent-a-room.
I finally caved in & signed on. Filled out forms, was told to provide bunch of info for an interview.
During interview inspector went through all details only to tell me that I shold not have applied becuse my gross the previous year was too high. (€60K).
So despite having paid 3K per month in VAT, PRSI & PAYE she told me I was not entitled to anything.
I then had to listen to her having a bit of a moan about her pension levy.
Spoke to my TD who said it should be appealed, that I was entitled to something.
Long & short of it was that I got a job before things got too bad.
Best advice I can give it to apply as soon as you can becuse there is a backlog and will take min 6 weeks to sort out (really longer though).
Call [broken link removed] for some help and advice.
Good luck - have a look at other threads here. You are not alone.
