Hi Shell77,
Three basic annual charges we face (besides utility bills)
1. Community charge collected by Resortalia for managing the site - you should contact them to sort out the standing order. This is collected quarterly
2. Local community charge to the local authority (Torre Pacheco in our case) - this needs to be set up with the Town Hall in Torre Pacheco, This can be paid on the spot and/or standing order set up. I can give you more details should you need it. This is due now and annually.
3. Non residents tax - this is paid to the tax office annually in Q4. Resortalia offer a fairly decent service to get this paid. Its a bit tricky in the 1st year as you need to fill out additional forms. You can go to a solicitors but they can often charge more than the tax itself. I believe you could try and sort it out yourself (tax office in Cartegena) but I don't know how difficult this would be.
If you want any more details on any of the above, I'd be glad to try and help.
