Apologies for new thread however i am, similar to Andi having difficulty posting a reply to the previous thread (other threads not a problem - strange)
From what I can understand:
Previously stated I had Catastral Value o E22617.30 - this is incorrect as it only represents my 50% share in property.
The total Valor Catastral for my brothers and my 3 bed on Naranjos is V.SUELO 18371,44 plus V.CONST 26.863,13 Total E45234.60
Rules changed last year so it is unclear whether a multiplyer of 2% or 1.1% is applicable for 2008 however as I completed in mid Oct the difference is about E20 overall so I have decided to overpay to be safe.
So for example Form 210 tax will be 45234.6 x 2% x 24% then prorata for the period I owned the property i.e mid Oct to end Dec.
i.e total tax for 08' = E45.21
All this has been made all the more simple by using http://spanishtaxforms.co.uk/ and paying £19.95 for the advice. John Bosdet at the site has been particularly helpful in correcting my previous errors.
P.S Catastral value for my prop was obtained by speaking to the Alhama Town hall on 0034 968 636 780
Hope this helps!
