You can import your vehicle completely tax free, if you have owned it for six months or more ( name on registration document/title ) and it is imported when you arrive to live in Spain.
This is significant, as tax is based on a combination of the Spanish fiscal valuation of the vehicle, and the Co2 emissions figure ( see figures below )
However, the tax may not be as much as you think ,especially for Co2 efficient or Electric/Hybrid vehicles.
Co2 tax payable
0 to 120 grms. Zero tax
121 to 159 grms. 4.75% of Spanish fiscal value
160 to 199 grms. 9.75% of Spanish fiscal value.
200 grms or above. 16% of Spanish fiscal value.
We will access your personal situation to advise of your tax free eligibility , or calculate the taxes payable accuratly for you.
It is always advisable to have the registration document in your name, regardless of your entitlement to a tax free importation, as otherwise a further 6% transmission tax is attracted !
