Employees who relocate to Spain from abroad, and who fulfil a series of obligations, can benefit from a generous tax regime.
You must not have been tax resident in the 10 years prior to the relocation and the employer must be a Spanish company or have a permanent establishment in Spain.
The employee may not own more than 25% of the company. Typically, the tax applicable is reduced from 45%+ to 24% and is applicable for a period of up to 6 years.
