High profile and high stakes: The Shakira Spanish tax case

In May 2026, Spain’s High Court acquitted Shakira of tax fraud in relation to her 2011 tax affairs, finding that the Spanish tax authority had failed to prove she was resident in Spain for that year. 

The case turned on a relatively simple statutory test: whether she spent more than 183 days in Spain. The court concluded she spent only 163 days in the country and that Spain was not the centre of her economic interests, nor did she have family ties with residents of Spain. As a result, assessments and penalties of more than €55m were overturned, and the Spanish tax authorities were ordered to reimburse her. We wait to see if the Spanish tax authorities will appeal with the Supreme Court.

While the headline rule appears straightforward, the case itself, running for nearly a decade, illustrates a deeper point: determining where an internationally mobile individual is “tax resident” is rarely as simple as counting days.

For many UK advisers, the themes underpinning the Shakira litigation will feel familiar. Before the introduction of the Statutory Residence Test (SRT) in 2013, UK tax residence was determined largely by case law and HMRC guidance. This created a position that was highly subjective, dependent on qualitative factors (e.g. centre of vital interests) and prone to protracted disputes.

The introduction of the SRT with effect from 6 April 2013 replaced the previous “multi-factor” approach with a structured, mechanical framework, comprising:

1. Automatic overseas tests (clearly non-UK tax resident),
2. Automatic UK tests (clearly UK tax resident — including the 183-day rule), and
3. The sufficient ties test, which determines the number of days you can spend in the UK based on your “ties” to the UK.

Crucially:

• The test operates in a prescribed order, with the effect that once a condition is met, the analysis stops;
• Day counting is codified (with specific rules as to what constitutes a “day” in the UK); and
• The interaction between days and ties is deterministic, not discretionary. 

However, this does not eliminate complexity. Indeed, the SRT is detailed and can produce unexpected outcomes, but it significantly reduces the scope for purely subjective arguments.

From a UK perspective, the SRT represents a deliberate shift away from the uncertainty that characterized the pre-2013 regime. Whilst not perfect, it provides a level of predictability that many other jurisdictions (as this case demonstrates) are still grappling to achieve.

For internationally mobile clients, the message is clear: keep meticulous records and understand the applicable residence tests in each jurisdiction to ensure you do not fall foul of the rules.
