Jersey wages are high compared to a very large % of the UK.
Tax is Tax, we are not taxed abnormally high here, have 5% GST instead of VAT and social is not a killer (Large % is paid by employer, rest is paid by you)
Cost of living is higher but depending on your personal circumstances I don't imagine you will be worse off, not unless you are taking a pay cut. If anything housing will be your main issue with regards to costs unless you get housing qualifications through your work or because you were born here. Even with qualifications housing is pretty expensive anyway so rather than look into taxation I suggest you look into accommodation.
The other outgoing will be parish rates, differs from parish to parish and the land your own/occupy. Think of it as council tax. It's not crippling though.
Leccy/Gas is pretty expensive compared to UK, just another factor of living costs though.
Out of curiosity What company/sector? Contracted or worked in many big corporates, which I imagine is what is bringing people in from UK.
Just think, can order from OcUK VAT free
