Many thanks for the responses. I have managed to find my initial contract which states that:
" the company will deduct Income tax (PAYE), PRSI and other agreed and statutory deductions at source. Your salary will be paid by Credit Transfer in monthly instalments...."
I worked for the company from the end of January to mid March so as you can imagine the sums are not huge but all the same.
I have tried to contact the liquidators to find out what taxes were paid however the liquidators have also gone bust. It gets more of a joke but a quick search of Irish airlines going belly should prove what I am saying. I honestly don't believe the airline ever paid taxes. Why did i not gain a PPS number? and after all any 16 year old could knock up a false paysheet.
The other problem is that the monies i did receive were not in monthly instalments at all, but were in 3 random chunks. The result is that some is due in tax year 05-06 and some effects 06-07 even though i only worked jan-March 06. Due to the "chunks" being random I have no way of determining the splits of what is income, FDA and ABA (FDA/ABA 65% tax free). Due to the other 2 payments being after 5 April 06 I can simply, i think, fill in an self assestment tax form for 06-07.
Its not an easy case and fear that seeking specialist tax advice would lead to me paying £200 / hour till the cows come home.
Should have been a doctor.
