How long do you have to accept an inheritance?

Tax deadline (ISD)

Law 29/1987 regulates ISD; each autonomous community may offer tax relief and require its own forms. The six-month period is the standard starting point for submitting the self-assessment. Check with the regional tax office whether extensions or special rules apply to your case.

Municipal capital gains tax (plusvalía municipal), the deceased's debts or other taxes may have different schedules. ISD does not replace them.

Acceptance and renunciation in civil law

The Civil Code (arts. 1004 et seq.) distinguishes between pure and simple acceptance, acceptance subject to benefit of inventory or renunciation. It does not set a universal 'month X' to accept: the inheritance is considered accepted in specific legal scenarios (actions that imply an intention to accept) or when an interested party serves you with a judicial or notary notice and you fail to renounce within the deadline.

A formal notice (interpellation) is the legal procedure used by a creditor or another interested party to compel you to declare your position. Ignoring it can amount to tacit acceptance depending on the circumstances. For this reason, it is advisable to make a decision with a solicitor before using the property, withdrawing funds from the deceased's bank accounts or selling assets.

Can I wait for years?

In practice, many families delay due to grief, disagreements or missing documentation. Meanwhile, the property remains registered in the deceased's name at the Land Registry, debts can accumulate and the heirs cannot complete a clean transfer. There is no automatic penal deadline of 'two years and you lose the inheritance', but inaction makes the process more costly and complicated.

Connection with selling the property

Buyers and notaries usually require accepted inheritance, partition or allocation, and registration prior to signing the public deed. Attempting to sell 'in parallel' without a clear title delays everything. The guide inheriting a property: steps before selling outlines this path.

Inheritances involving multiple heirs

If one heir accepts and another does not, or if there are specific bequests and a surviving spouse's life interest (usufruct), the timeline is no longer purely tax-related: a partition agreement or judicial proceedings become necessary. The six-month ISD deadline does not wait for family reconciliation; sometimes it is advisable to request an extension or make a provisional tax filing based on professional advice.

Preliminary documentation

• Death certificate and certificate of last wills.
• Will or declaration of heirs intestate.
• Inventory of assets and liabilities (mortgage, loans, unpaid debts).
• Indicative valuations for ISD tax purposes and for negotiating among heirs.

Common mistakes

Believing that 'I have not accepted yet' exempts you from taxes, using the inherited property as your own without formal procedures, or signing a deposit agreement without registered authority. Another mistake is confusing the ISD deadline with time limits for claims against the estate or against co-heirs.

International inheritances

If the deceased or the assets have links outside Spain, foreign laws, multiple wills and consular certificates may be involved. The six-month ISD deadline remains an urgent landmark within Spanish territory, but obtaining documentation may take longer. Plan ahead for sworn translations and apostilles.

Extensions and deferrals

The regional tax authority can grant an extension to the ISD deadline if you request it within the statutory timeframe and provide valid grounds. It is not automatic: you must submit the official form and justification. In the meantime, avoid actions that amount to tacit acceptance if you are still considering renunciation or acceptance subject to benefit of inventory.

Will pending location

If the certificate of last wills is delayed, the tax clock continues ticking in most cases. Initiate notary and consular procedures early if assets are located across multiple countries to avoid reaching the sixth month without a clear title.
