The part of Spain offering a 60% tax break that most Costa expats cannot use

Skilled foreign workers moving to Bizkaia, the Basque province that includes Bilbao, could benefit from a proposed 50 per cent income exemption, rising to 60 per cent for under-36s. But the deal is still being processed, and comes with strict regional rules and a postcode catch many expats may miss.

One Spanish postcode could change the tax bill for new arrivals

For British workers thinking about a move to Spain, the biggest financial pull may not be on the Costa del Sol, Costa Blanca or Balearic Islands.

A proposed tax reform in Bizkaia, the Basque province also known as Biscay and home to Bilbao, could give some skilled workers a major income tax advantage if they relocate there for work. The measure is already attracting attention because of one hard-hitting figure: a possible 60 per cent exemption on certain work income for people under 36.

Unfortunately, this is not a Spain-wide tax break. It is a proposed regional measure tied to Bizkaia’s own tax system, with its own rules and conditions. 

How Bizkaia’s proposed 60% worker tax break would work

The Provincial Council of Bizkaia, known in Spanish as the Diputación Foral de Bizkaia, says its 2026 tax measures are designed to attract and retain qualified workers, support businesses and make it easier for people to settle in the territory.

Under the proposal, Bizkaia would increase the exemption on income from professional activity to 50 per cent. For workers under 36, that figure would rise to 60 per cent. The province also plans a new deductible expense for geographical mobility linked to work, worth €2,000 a year during the year of the move and the following three years. For under-36s, that would rise to €3,000.

The measure relates to Personal Income Tax, known in Spain as Impuesto sobre la Renta de las Personas Físicas (IRPF), the main tax residents pay on earnings and other income.

For a young professional choosing between job offers in different parts of Spain, the difference could be huge. For a retiree, holiday homeowner or self-employed person already living elsewhere in Spain, the picture is much less straightforward.

Why most expats in Spain would not qualify automatically

The proposal is aimed at workers displaced from abroad or moving for employment reasons, not at all foreign residents already living in Spain.

Tax firm EY says the draft reform would simplify access to Bizkaia’s special regime for workers arriving from abroad, remove restrictions on some professional activities, reduce the regime’s duration to eight years and increase the income exemption to 50 per cent, or 60 per cent for under-36s. EY also notes possible extension to certain family members, depending on the conditions.

Andersen, another tax and legal firm, says the draft is still in the public hearing stage and may change during processing. Its analysis says the special regime would be reshaped for displaced workers, with the exemption rising from 30 per cent to 50 per cent, or 60 per cent for under-36s, while the duration would fall from 11 years to eight.

However, a British resident already settled in Alicante, Malaga, Murcia or Mallorca should not assume this can be claimed simply by moving paperwork around. Location, previous residence, employment status, age, timing and the type of work are all likely to matter.

Why this is not the same as Spain’s Beckham Law

Many expats already know Spain’s national inbound worker regime as the Beckham Law. Officially, it is the special tax regime for workers posted to Spanish territory under Article 93 of Spain’s Personal Income Tax Law. Spain’s Tax Agency says taxpayers who want to opt into that national special regime must use Form 149 and meet registration and documentation requirements. 

Bizkaia is different because the Basque Country has a special tax framework known as the Concierto Económico, or Economic Agreement. The Bizkaia authority itself says the draft tax package uses that fiscal capacity to respond to economic and social challenges in the province.

Why Bizkaia wants workers to stay

The proposal is not only about attracting foreign professionals. Bizkaia says the wider tax package is intended to help companies remain rooted in the province, deal with generational change in businesses, improve worker loyalty and support access to housing.

Now Spain’s regions are not only competing for tourists and second-home buyers. They are also competing for skilled workers, younger professionals and companies that can bring long-term employment.

For British workers who can choose where to live, tax may now sit alongside the big factors people weigh up when moving to Spain: climate, language, schools, housing costs and flights back to the UK.

The tax saving only matters if the move fits the life

For anyone looking at Spain from abroad, Bizkaia’s proposal may add a new name to the relocation shortlist. Bilbao and its surrounding province can now be weighed not only against Madrid, Malaga, Alicante or Valencia, but against the possible tax difference that could come with choosing one postcode over another.

That does not make the decision easy. A lower tax bill will not solve housing pressure, language barriers, school choices, family distance or the practical reality of building a life in northern Spain rather than on the Mediterranean coast.

It also doesn’t mean every new arrival will qualify. The reform is still being processed, and the benefit will depend on the final wording, the worker’s age, previous residence, employment situation and whether the move genuinely falls within Bizkaia’s rules.
