Tensions flared again at Spain’s southern frontier on 2 November after Andalucía’s Tourism and External Action Minister, Arturo Bernal, blasted the central government for “opacity” in ongoing talks with the UK over Gibraltar’s future fiscal status. Speaking in Seville, Bernal claimed that Madrid has excluded the regional executive from negotiations that will directly affect more than 15,000 Spanish commuters who cross ‘la Verja’ daily to work in the British Overseas Territory.
The still-unfinished pact—designed to replace EU frameworks lost after Brexit—covers corporate taxation, social-security coordination and the treatment of remote workers resident in Spain. Bernal warned that lack of clarity on withholding rules and double-tax relief is already complicating payroll for Andalusian SMEs that post staff to Gibraltar’s booming online-gaming and fintech sectors. He also fears a “race to the bottom” on company tax that could drain investment from neighbouring Campo de Gibraltar municipalities, which suffer Spain’s highest unemployment rate (28%).

For global-mobility managers, the episode underscores the regulatory grey zone that has persisted since the UK left the EU in 2020. Employees who reside in Spain but hold Gibraltar contracts currently face dual reporting obligations and patchy access to Spanish welfare benefits. Tax advisers say the new accord must spell out which jurisdiction enjoys taxing rights on income earned partly in each territory and how social-security contributions will be totalised.
Failure to involve regional authorities could also complicate implementation. The Junta de Andalucía controls regional employment offices and vocational-training funds used by many Gibraltar-based firms for upskilling Spanish staff. Bernal hinted that the Junta might set its own conditions for cross-border licences if Madrid signs a deal viewed as unfavourable.
Until the text is published, companies with staff shuttling between Algeciras, La Línea and Gibraltar should maintain conservative tax withholding, review permanent-establishment exposure and anticipate possible changes to commuter-pass arrangements at the border—especially once the EU Entry/Exit System becomes mandatory in 2026.
