IBI local council tax can be paid at Al Kasar council office, you need your blue form . I am sure i have put a document on doc folder some time ago.. Income tax is the other tax due and www.spanishtaxforms.co.uk has always had a good report. The local lawyers through mil Lev also do it speak to David at Office,
Wealth tax is another matter and unless you have an expensive villa eleswhere in Spain or loads in Spanish account - not wise , then probably does not apply.
