Basura
That is determined by the town hall. They produce a bill
Wealth Tax
Unless you are talking about an incredibly luxurious home, in effect it no longer exists
IBI Rates – we have had different opinions on this one as some people insist you should wait till the casteral value for your house has been determined and the IBI demanded before you pay it while other people are paying it already.
That is determined by the town hall. They produce a bill. I don't believe you can pay it before that.
Community Charge
That is determined by the community and they will tell you.
Anything else?
If you are non resident then you will also have to pay the Non-Residents Property tax. More or less 0.5% of the catastral value, or the declared price in the Escritura, which ever is the higher. If you are resident then income tax on your worldwide assets (with a couple of exceptions, including a government employee pension, this is not OAP, and property which you let in another country)
It would be good to get some direction so that when we approach a gestor we have an idea of what we should be paying for.
A gestor will probably advise you for free
How much does a gestor charge – any indication would be good.
Again, depends how lucky / unlucky you are with choosing the gestor, Ask around. example. I am resident and pay 40 euros for a full tax return for my wife and myself.
