If administration has not started, we organise the decisions, evidence and deadlines. If the estate is already stuck, we identify what is missing and coordinate tax, notary, local tax, Cadastre and Land Registry work through completion.

Heirs and legatees are the taxpayers for Spanish Inheritance Tax. Each heir's tax residence determines whether the acquisition is subject to personal or real liability; the competent tax authority and the State or regional rules that apply are then determined under the relevant connecting factors.
Those obliged to pay and file the tax are the heirs (who succeed universally) and legatees (who receive specific assets) who acquire assets and rights due to death or hereditary succession.
The applicable regional rules cannot be determined by a single shortcut. In a domestic inheritance governed by the common system, they generally connect with the deceased's habitual residence, determined by the greatest number of days during the five years immediately preceding the chargeable event. If the deceased or any heir is non-resident, each taxpayer's residence and the location of the estate must also be reviewed, because the special rules for non-devolved cases may apply.
An heir resident for Spanish tax purposes is subject to personal liability on the worldwide acquisition, even if the deceased lived abroad. A non-resident heir is subject to real liability on assets and rights situated, exercisable or payable in Spain. The competent tax authority and the State or regional rules are then determined under the applicable connecting factors.
The documentation required to process an inheritance may vary slightly depending on the Autonomous Community, but generally the following is required (original or certified copy):
Correctly and timely filing of Inheritance Tax is crucial not only to avoid penalties but also to be able to register inherited assets (real estate, vehicles) in the names of the new owners in the corresponding registries (Property Registry, Traffic, etc.).
State regulations for Inheritance Tax establish basic reductions, but Autonomous Communities (ACs) have extensive powers to significantly improve them or introduce important allowances on the tax liability. It is crucial to know the specific regulations of the applicable AC to correctly apply the available reductions and allowances.
There are very significant state and regional reductions depending on the degree of kinship with the deceased (Groups I and II: direct descendants, direct ascendants, spouse). Many ACs also apply significant allowances on the tax liability for these groups, in some cases reaching 99% or even 100%.
Reduction in the taxable base for the acquisition of the deceased's primary residence (generally 95%, with maximum limits varying by AC), if the heirs are spouse, ascendants, or descendants (or collaterals over 65 who lived with the deceased) and meet maintenance requirements for a specified period.
Reduction of up to 95% (or more depending on AC) in the value of shares in entities or individual family businesses, if strict requirements for maintaining the activity and shares by the heirs are met.
Additional reductions for heirs with a recognized degree of physical, mental, or sensory disability, the amount of which varies according to the degree of disability and AC regulations.
Reduction of 100% with a state limit of €9,195.49 on amounts received from life insurance contracts, when the beneficiary is the spouse, ascendant or descendant of the deceased policyholder. Some Autonomous Communities improve this limit or apply specific rules, so the regional regulations applicable to each case should be checked.
Applicable reduction (generally 95%) for the acquisition of assets listed in the General Inventory of Spanish Historical Heritage or equivalent AC registries, under certain conservation and maintenance conditions.
The Community of Madrid is one of the ACs with the greatest tax benefits in Inheritance Tax for direct relatives:
This may significantly reduce the tax burden for close relatives in Madrid, and reduced by half for siblings, uncles/aunts and nephews/nieces (by consanguinity and affinity) from July 2025.
Each case should be reviewed individually, especially when the estate includes property, non-resident heirs, life insurance policies or multiple heirs with different degrees of kinship.

For estates with real estate, in addition to Form 650 there may be a plusvalía municipal (Spanish municipal capital gains tax on the increase in the value of urban land). It is a local tax charged separately by the city council where each property is located, with its own deadlines, taxpayers and allowances. At GESTISYD we also review the plusvalía municipal and coordinate its filing when you engage us for the full estate administration.
The Inheritance and Gift Tax (IGT) is a direct and subjective tax levied on wealth increases obtained by individuals free of charge. The Inheritance modality applies to acquisitions of assets and rights due to death (inheritances, legacies, and other succession titles).
Those liable for payment of the tax as acquirers (taxpayers) are:
The tax becomes due (i.e., the obligation to pay it arises) on the day of the deceased's death (the person leaving the inheritance) or when the declaration of death becomes final. The deadlines for its settlement and payment begin from this date.
The general deadline for filing the self-assessment or declaration of Inheritance Tax (Model 650) is 6 months, counted from the day of the deceased's death or from when the declaration of death becomes final.
Failure to file the tax on time can have several negative consequences:
The taxable base starts from the value of the assets and rights acquired. In general, market value applies, or the declared value if higher. For real estate, the cadastral reference value at the date of death applies, or the declared value if higher. If no certifiable reference value exists, the higher of declared value and market value applies, subject to administrative review. The statutory rules on additions, charges, debts and deductible expenses are then applied.
Spanish inheritance tax includes a presumption that the deceased's household goods ("ajuar doméstico") are worth a percentage of the estate. The general rule presumes 3% of the computable estate, but following Spanish Supreme Court case-law from 2020, this percentage does NOT apply to the entire estate: it only covers assets actually used for personal/domestic purposes (mainly the principal and secondary residences). Bank balances, investment funds, shares, receivables and other assets not subject to domestic use must be excluded from the calculation. The taxpayer can rebut this presumption with evidence. We review this case by case, especially when the estate includes property and significant financial assets.
Yes, significantly. Autonomous Communities have broad regulatory powers.
Yes. Taxpayers can request an extension of the filing period for an additional 6 months. This request must be made within the first 5 months of the initial filing period (i.e., before the end of the fifth month from death). Granting the extension entails the accrual of late payment interest corresponding to the extension period but does not prevent the application of surcharges if the filing is made after the granted extension has ended.
The main form for the self-assessment of Inheritance Tax is Model 650.
