Why might executives avoid living in Spain while working in Gibraltar?
Short answer
Living in Spain usually makes you Spanish tax resident, so a Gibraltar salary is also taxed in Spain, where rates are generally higher, and Gibraltar's executive regime HEPSS requires approved accommodation in Gibraltar. Housing in Spain is cheaper, so the decision turns on income level, family circumstances and commuting time.
Detailed answer
Tax If you spend more than 183 days a year in Spain or your centre of economic interests is there, Spain taxes your worldwide income, including your Gibraltar salary, with a credit for Gibraltar tax. For higher earners the Spanish top-up can be substantial. Under the 2019 UK-Spain tax agreement, someone whose only permanent home is in Spain, or who spends more than 183 nights there, is treated as resident only in Spain. Loss of Gibraltar regimes HEPSS, which caps taxable income at the first £160,000, requires approved residential accommodation in Gibraltar for the executive's exclusive use. An executive living in Spain also cannot expect to obtain a Gibraltar tax residence certificate: the Income Tax Office looks at where the applicant's home, finances, family and social life are, and gives most weight to evidence such as a Gibraltar identity card, health card, local utility bills and day-to-day spending in Gibraltar. The frontier The UK-EU treaty on Gibraltar has applied provisionally since 15 July 2026 and is designed to ease movement across the frontier. Daily commuting still takes time, which matters for executives with demanding schedules. Living in Gibraltar Since 14 July 2026 living in Gibraltar requires a residence permit, with a primary residence in Gibraltar that is owned or rented for at least 12 months.
