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.
