Are We Still UK Domiciled After Living in Spain?

Residency and Domicile Are Not the Same Thing

This is where most confusion begins.

Residency answers:

“Where do you live now?”

Domicile answers:

“Where do you ultimately belong in law?”

You can change residency relatively quickly.

Changing domicile is far more complex.

Living in Spain for several years does not automatically change your UK domicile.

That distinction has significant consequences for inheritance tax.

How UK Domicile Is Determined

Under UK law, domicile is generally acquired at birth.

Most British nationals have a UK domicile of origin.

Changing domicile requires:

• Severing ties with the UK
• Establishing a permanent intention to reside elsewhere
• Demonstrating that intention through consistent actions

Intention is central.

Courts assess:

• Where you consider your permanent home
• Where you hold long-term assets
• Where you expect to retire
• Where family ties remain
• Whether you maintain UK property
• Whether you retain UK burial wishes or long-term plans

Domicile does not shift automatically when you relocate.

Why Moving to Spain Does Not Automatically Change Domicile

Many expats say:

“We’ve left the UK.”

“We pay tax in Spain.”

“We don’t plan to return.”

Those statements may reflect current life.

They do not automatically prove permanent intention to abandon UK domicile.

If:

• You retain UK property
• Your children remain in the UK
• Your estate planning assumes return
• You describe Spain as temporary
• You maintain long-term UK ties

UK domicile often persists.

The burden of proof sits with the individual asserting change or back to uk

Deemed Domicile Rules

Even if domicile of origin is lost, UK deemed domicile rules may apply.

Under current UK legislation, individuals may be deemed domiciled in the UK for inheritance tax if:

• They have been UK resident for 15 of the previous 20 tax years
• Or they were UK domiciled within the previous three years

This creates complexity for long-term expatriates.

Spanish residency does not override UK deemed domicile rules.

It is entirely possible to:

• Be tax resident in Spain
• Be non-UK resident
• And still be UK deemed domiciled for inheritance tax

This is often discovered too late.

Inheritance Tax Consequences

If UK domiciled or deemed domiciled:

• Your worldwide estate may be subject to UK inheritance tax
• UK IHT currently applies at 40 percent above available thresholds
• UK situs assets are always within scope

Spanish residence does not remove UK IHT exposure.

Spanish succession law and UK inheritance tax operate independently.

This is where cross-border planning becomes technical.

How Spanish Residency Interacts With Domicile

Spain determines tax residency based on:

• 183-day rule
• Centre of vital interests

Domicile is irrelevant for Spanish income tax residency.

However:

• Spain may apply its own succession tax rules based on residency
• UK may apply inheritance tax based on domicile

This creates potential dual exposure.

Understanding which system applies to which asset category is critical.

Why This Becomes Relevant Later

Domicile rarely causes stress early.

It becomes critical when:

• Estate planning begins
• Large assets accumulate
• Trust planning is considered
• A spouse dies
• Children inherit
• Property is transferred

At that point, assumptions made years earlier are tested.

The question is not:

“Where do we live?”

It is:

“Where are we legally tied?”

Common Misinterpretations

Frequently heard:

• “We’ve been gone 10 years, so we must have changed domicile.”
• “We pay tax in Spain, so the UK cannot apply inheritance tax.”
• “We have a Spanish will, so the UK is irrelevant.”

Each statement is incomplete.

Residency does not cancel domicile.

Spanish succession documentation does not override UK inheritance tax.

When Domicile Review Is Essential

You should review domicile position if you:

• Have lived in Spain more than three years
• Hold significant UK assets
• Intend to remain abroad permanently
• Are approaching retirement
• Are considering trust structures
• Have children in multiple jurisdictions

For modest estates, exposure may be limited.

For structured wealth, ignoring domicile is negligent.

Evidence of Intention Matters

If you intend to change domicile from the UK to Spain, evidence may include:

• Selling UK property
• Severing long-term UK ties
• Establishing permanent property in Spain
• Clear statements of long-term intention
• Updating estate documentation accordingly

This is not a box-ticking exercise.

It is a narrative supported by action.
