UK Ltd Company When You Live in Spain: What Changes After Brexit

The Post-Brexit Landscape for UK Ltd Owners in Spain

Before Brexit, UK Ltd companies with Spanish-resident shareholders operated in the comfort of the EU Parent-Subsidiary Directive (PSD) and EU Interest and Royalties Directive — frameworks that largely eliminated withholding taxes on cross-border income flows within the single market. The UK's departure from the EU on 31 December 2020 fundamentally changed this: those EU directives no longer apply to UK companies, and the UK-Spain tax relationship is now governed exclusively by the 1975 Spain-UK Double Tax Convention (as amended by the 2014 Protocol).

For the hundreds of thousands of British nationals living in Spain who own or have owned UK Ltd companies, this creates a more complex and potentially more expensive tax position than existed before 2021. This guide explains what has changed, what risks have emerged, and what planning options remain available.

Pre-Brexit vs Post-Brexit: The Key Differences

Under the EU framework (pre-31 December 2020), a Spanish-resident shareholder receiving dividends from a qualifying UK parent or subsidiary benefited from the Parent-Subsidiary Directive's zero withholding tax on dividends where the EU company held at least 10% of the paying company for at least one year. The directive applied regardless of where the ultimate owner was resident.

Post-Brexit, this protection is gone. Dividends paid from a UK Ltd to a Spanish-resident individual are now subject to:

• UK withholding tax at the domestic rate of 0% (UK domestic law does not impose withholding tax on dividends paid to individuals — this is actually a more favourable position than many EU countries)
• Spanish IRPF on the gross dividend received, at savings income rates of 19-28%
• A credit under Art. 80 LIRPF for any UK tax withheld (which in the case of dividends paid to individuals is usually 0%, so the credit is nil)

The absence of UK dividend withholding tax for individual shareholders is therefore somewhat fortuitous post-Brexit — the change to treaty-only status has not, in the dividend context for individuals, significantly worsened the position compared to the PSD era.

Where the position has deteriorated is for corporate structures: a Spanish holdco receiving dividends from a UK subsidiary can no longer rely on the PSD zero rate and must use the treaty's 10-15% WHT provision, compared to the 0% that applied under the PSD.

The Permanent Establishment Risk: Directors in Spain

The most significant risk for UK Ltd owners who have moved to Spain is the permanent establishment (PE) question. Under the Spain-UK DTT (Art. 5) and Spanish domestic law (Art. 13 LIRNR), a UK Ltd has a PE in Spain if it carries on business through a fixed place of business in Spain, or through a dependent agent — an individual who habitually exercises authority to conclude contracts on behalf of the company.

The practical risk is this: if you are a UK Ltd director resident in Spain, and you are making all significant business decisions — negotiating and signing contracts, managing client relationships, directing the company's operations — from your Spanish home or office, the AEAT can credibly argue that the UK Ltd has a PE in Spain. The consequences:

• Spain asserts the right to tax profits attributable to the Spanish PE at the Spanish IS rate (25%)
• The UK Ltd now has a Spanish tax filing obligation (Modelo 200 or non-resident returns)
• Potential double taxation: the UK taxes the company's worldwide profits at UK corporation tax rates (25% from April 2023); Spain taxes the PE's attributed profits at 25%
• The Spain-UK DTT's PE provision (Art. 7) should protect against double taxation — but only if the company actively claims treaty protection and allocates profits to PE and non-PE activities on a defensible basis

The PE risk is fact-specific. A UK Ltd with multiple UK-based directors and employees, genuine UK operations, and a Spanish director who participates in management but does not solely control the company is in a fundamentally different position from a sole-director UK Ltd where 100% of commercial activity occurs from Spain.

Dual Residency: Can Your UK Ltd Be Tax Resident in Both Countries?

Under UK domestic law, a company is tax resident in the UK if it is incorporated in the UK or if its central management and control (CM&C) is exercised in the UK. If a UK Ltd is effectively managed and controlled from Spain — because its sole director or board of directors is in Spain and all key decisions are made in Spain — HMRC may argue CM&C has shifted to Spain, making the company non-UK resident for UK corporation tax purposes.

Simultaneously, Spain's domestic corporate residence rule (Art. 8 LIS) holds that a company is tax resident in Spain if its registered office is in Spain, if its effective management seat is in Spain, or if its principal activity or economic activity is carried on from Spain. This creates the potential for dual residency — both HMRC and the AEAT claiming the UK Ltd as their resident entity.

The Spain-UK DTT's tie-breaker rule for companies (Art. 4(3)) resolves dual residency by reference to where the company's "effective management" is located. If effective management is in Spain, the company is treated as Spanish-resident under the treaty — meaning Spain has primary taxing rights on the company's worldwide profits, and the UK treats the company as non-resident (subject to UK tax only on UK-source income). This is a catastrophic outcome for many UK Ltd owners who assumed their company would remain safely UK-resident.

Spanish CFC Rules and the UK Ltd

Spain's Controlled Foreign Corporation (CFC) rules (Art. 100 LIS for corporate shareholders; Art. 91 LIRPF for individual shareholders) may require a Spanish resident who controls a foreign company to include that company's undistributed passive income in their Spanish tax base.

For an individual Spanish resident owning a UK Ltd that generates passive income (dividends from investments, rental income, interest), the individual CFC rules may apply where:

• The Spanish resident holds more than 50% of the UK Ltd
• The UK Ltd's income is primarily passive
• The UK Ltd pays corporate tax at less than 75% of the Spanish IS equivalent on that income

Given the UK's 25% corporate tax rate (matching Spain's IS rate), the 75% test is generally satisfied for UK Ltd companies paying full UK corporation tax. However, UK Lts that benefit from R&D credits, the patent box regime, or other UK tax incentives that reduce their effective rate may fall below the 75% threshold, triggering Spanish CFC attribution.

Dividends from UK Ltd to Spanish Residents: Tax Treatment

As noted above, UK domestic law does not impose withholding tax on dividends paid to individual shareholders. The dividend reaches the Spanish resident without UK deduction. In Spain, it is taxed as savings income (rendimiento del capital mobiliario) at 19-28% on the gross amount.

There is no credit for UK corporation tax paid by the UK Ltd at the entity level — this is the classic economic double taxation of dividends, with the first level of tax being UK corporation tax (25%) and the second level being Spanish IRPF (19-28%). The Spain-UK DTT does not provide for an underlying tax credit on dividends (known as a "tax sparing" or "avoir fiscal" credit) in the way that some older treaties did.

Should You Close Your UK Ltd When Moving to Spain?

This is the question most clients ask. There is no universal answer, but the key considerations are:

• If the UK Ltd has genuine UK operations: Clients, contracts, employees, and commercial relationships in the UK — the UK Ltd has a valid commercial reason to exist and the PE risk is manageable if the Spanish director's role is clearly subsidiary to the UK management.
• If the UK Ltd is a personal service company with all work done from Spain: Closing the UK Ltd and operating through a Spanish SL or as an autónomo is almost always cleaner from a tax perspective. The tax savings from avoiding the PE risk and dual residency exposure usually outweigh the transition costs.
• Timing of closure: If closing, it is generally better to close the UK Ltd before becoming Spanish tax resident. A liquidation distribution while you are still UK-resident may benefit from UK entrepreneur's relief (Business Asset Disposal Relief) at 10% on qualifying gains — a rate that will not be available once you are Spanish-resident and gains are taxed at Spanish savings income rates (19-28%).
• Beckham Law as a bridge: If you qualify for the Beckham Law, maintaining the UK Ltd for up to six years while enjoying the foreign income exemption can allow an orderly transition without triggering immediate adverse tax consequences in Spain.
