Inheritance tax FAQ
- When is form 650 due?
- 6 months from death. You can request an additional 6-month extension within the first 5 — granted essentially automatically. Tax accrual: date of death.
- Do I owe ISD if I live abroad?
- If the deceased or the asset is in Spain, yes. After Supreme Court 2018, EU/EEA non-residents can apply the more favourable regional rules (Madrid, Andalucía, etc.). For third countries it depends on the tax treaty.
- What bonuses apply in my region?
- Madrid, Andalucía, Galicia, Murcia, Cantabria, Extremadura, Castilla y León, Canarias and La Rioja apply 99 % or more bonus to Groups I (descendants <21) and II (spouse + descendants ≥21 + ascendants). Other regions apply their own progressive schedules.
- What documents do I need?
- Death certificate + last-will + life-insurance certificate · heir IDs · will or court declaration of heirs · asset inventory (deeds, bank balances, valuations, vehicles) · debts and charges. We send the full checklist at intake.
- Can I defer payment?
- Yes. AEAT and every region accept ISD payment deferral up to 12 months without guarantee, longer with surety. Habitual residence has a special 5-year deferral. We file the request with the return.
