Law / UK National Insurance and Polish ZUS and tax issues [11]

Hello,

I am British yet I am resident and also work full time in Poland. I carry out all of my work in Poland and therefore my total income is from Poland. I would like to carry on paying my National Insurance contributions in the UK, but I need to get my Polish taxes in order.

It seems that it would be more beneficial to keep up my NI contributions and paying ZUS would be a waste.

I read a newspaper article (Dec 2012) which roughly stated the following…

After 20 years of paying the minimum social insurance in Poland / the UK:
ZUS in Poland: Pay £180 now & receive £120 pension per month
NI contributions in the UK: Pay £15 now & receive £600 pension per month

I have a couple of questions regarding tax in Poland/the UK:

1) Is it possible to be registered as self-employed in the UK yet receive all my income from Poland?
(I would pay my NI contributions in the UK and my income tax in Poland)

2) Do I only pay income tax in Poland if I have an A1 form?
(I understand that I can pay my NI contributions in the UK and am therefore exempt from paying ZUS in Poland)

Many thanks in advance for your suggestions.
