Not sure about speeding fines but so far as taxation notices are concerned these are issued by your local government authority…Your vehicle’s change of address should be notified to them.
You can do this via
Click on ‘?D?nde se puede solicitar?’ this will open up a window asking for your Province then Poblacion. The poblacion lists those towns in the province where you can change your vehicles address and where in those towns such as the town hall (ayuntimiento)
The following is a Google translation of the documentation required;
Proof of address change: ID card, certificate of residence, census card, etc.. If no change of municipality with proof of sufficient water, electricity, gas, etc.
For Relocation of vehicles from the Canary Islands, Ceuta and Melilla on the Peninsula or the Balearic Islands, provide supporting evidence that the vehicle has cleared customs. If not provide the document will inform the Customs Department.
Documentation of vehicle:
registration certificate (except in case of loss or theft) and ITV card with the recognition effect.
Hope this helps…
