I have some loan notes with Iberdrola following the takeover of Scottish Power.
Interest was given recently, and the spanish gov. took 18% "witholding tax" that they apply to non-residents of Spain, which leaves me to pay another 2% tax to the UK gov.
It's only a small sum left to pay (~£16) but does anyone know how I actually make the payment ?
I have some sort of certificate from Equiniti to say 18% has been taken already which I guess will have to be submitted somehow as proof to avoid dual taxation, but there are warnings about not losing it / costs to replace it.
Knowing what the UK gov. is like for losing stuff, can I send a copy of this paperwork ?
