Spanish tax return - working in Gibraltar

I understand that I will have to do a Spanish tax return even though I work in Gibraltar.  My company will be giving me a summary document of my earnings and tax paid.  Do I also need to get something from my Gibraltar bank showing average balance, interest received etc. like you get from Spanish banks?

Thanks in advance.

Can anyone help with this please?

Hi,  I have the same problem and I'm currently looking into it.  Found this helpful.

Thanks daniela.  The Spanish lads in the office don't declare their Gib accounts.  They just get something from the company stating their earnings and tax paid.  I think that's all I will do.

Most people don't.  But you are supposed to.  I own property in Spain and I am legally Spanish so I'm in the "system" in Spain so I think I'd better do it just in case they chase me later on.
