RE: Spanish Tax Forms due to be filed now7 Jan 2026 11:55
They are only free from CGT if you report the gain on a modelo 210 form. This, as previously shared, has to be submitted to the Spanish Tax authorities on the following January after the sale of the shares, regardless of the vehicle you use to hold those shares. Due to a double tax treaty between the UK and Spain, no CGT will be due if you report correctly. Failure to report the gain may mean that a penalty would be due. What i cant work out is how they serve said penalty or the consequences of not paying any penalty. The investor pages on IAG listed a company called spanish tax tax forms that do all this for you, albeit for a flat fee. The same company is also quoted on the Santander website so i assume its a bonafide company. If anyone has done this I'd be interested in how you got on with it all.
