Inheritance Tax in Spain for Foreigners: Rates, Deadlines, and Regional Rules

Spanish inheritance tax is an individual obligation — each heir files and pays separately, based on their relationship to the deceased, the value of what they inherit, and which region of Spain the assets are located in. The regional variation is enormous, and this is where most English-speaking families either overpay or miss deadlines they didn't know existed.

The 6-Month Filing Deadline

From the date of death, heirs have exactly 6 months to file and pay the Impuesto sobre Sucesiones y Donaciones (ISD) using Modelo 650 at the regional tax office. This is not a suggestion — it's a hard deadline with automatic penalties.

Miss it, and you face surcharges (recargos) of 5% to 20% of the tax owed, plus daily interest (intereses de demora) calculated retroactively from the original deadline.

The 5-Month Extension Trap

If the estate is complex — involving foreign assets, consular delays, or cross-border probate — heirs can request a 6-month extension (prorroga). But the request must be submitted within the first 5 months of the initial 6-month period.

This catches families who assume they can request more time at the last minute. An extension request filed in month 6 is automatically denied. The practical advice: review the estate's progress by month 3. If international paperwork is causing delays, file the extension request immediately using Modelo 739 at the relevant regional tax office.

The extension prevents late-filing penalties but does not stop interest from accruing. Interest starts from month 6 regardless of whether an extension was granted.

Regional Rates: Why Location Matters

Spain's inheritance tax is administered by the 17 autonomous communities, and the differences are dramatic:

Low-tax regions: Madrid, Andalusia, and the Valencian Community offer substantial reductions — in some cases up to 99% — for direct family members (spouse, children, parents). An estate worth EUR 500,000 inherited by a spouse in Madrid might generate almost zero tax.

Higher-tax regions: Catalonia, Aragon, and Asturias apply lower reductions, meaning the effective tax rate on the same estate could reach 10% to 20% or more.

The tax is assessed where the deceased had their habitual residence (residencia habitual), defined as the region where they spent the most time in the 5 years before death. For an expat living on the Costa Blanca, that's the Valencian Community. For someone in Barcelona, it's Catalonia.

Non-Resident Heirs

If the heirs are non-residents of Spain (living in the UK, US, or elsewhere), they still owe Spanish inheritance tax on assets located in Spain — property, bank accounts, vehicles. Since a 2014 EU Court ruling, non-resident EU/EEA heirs can apply the same regional reductions as residents. Non-EU heirs (Americans, Canadians) can also claim these reductions under current Spanish practice, though the legal basis is less settled.

Non-residents file with the national AEAT tax office in Madrid rather than a regional office.

How to Pay Tax from Frozen Bank Accounts

This is the practical question families struggle with most: the bank accounts are frozen, but the tax office wants payment before they'll release the funds. It feels circular, and it is — but there's a legal route through.

Heirs can request that the bank issue a payment directly to the regional tax office from the deceased's frozen funds. The bank is legally permitted to do this. You'll need the Modelo 650 tax assessment showing the amount due, plus the standard testamentaria documentation (death certificate, will certificate, heir identification).

Some regional tax offices also offer instalment payment plans (fraccionamiento) for large tax bills, though interest applies.
