Deferring or splitting Spanish Inheritance Tax when the estate has no cash

Inheriting does not always bring money. Very often it brings a flat, and Hacienda (the Spanish tax authorities) demands a tax bill that has to be paid within 6 months. The law foresaw exactly that problem and created a regime of its own, separate from the general one: articles 37 to 39 of Ley 29/1987 del Impuesto sobre Sucesiones y Donaciones (the Spanish Inheritance and Gift Tax Act) and articles 82 to 85 bis of its implementing regulation, Real Decreto 1629/1991.

Deferring means pushing the whole payment back to a later date. Splitting means breaking it into several staggered payments. It is not a write-off: the tax is paid in the end, and, except in the special cases, with interest. What you gain is time to sell, to rent out or to raise the money without the debt going into enforced collection.

The underlying requirement is the same in every form of the special regime: that the deceased's inventoried estate holds no cash and no readily realisable assets sufficient to pay the tax (articles 82.b and 83.b of the Reglamento, the implementing regulation). A bank balance or listed shares are readily realisable assets. A flat, a commercial unit or a stake in a family company are not. That is why the lack of liquidity has to be evidenced with an inventory: simply stating it is not enough.

This special regime covers only acquisitions on death: inheritances and legacies. Lifetime gifts fall outside it and go through the general regime of article 65 of the Ley General Tributaria (the Spanish General Tax Act). The tax is devolved to the comunidades autónomas (Spain's regional governments), so the body that decides your application is the competent region, not the state Agencia Tributaria (AEAT, Spain's national tax agency). Managora identifies which one it is, prepares the application and files it with that office on your behalf.

The deadline to file and pay Spanish Inheritance Tax is 6 months counted from the day of death (article 67.1.a of the Reglamento). That is the date everyone knows. The one almost nobody knows is the second one.

The application to defer or to split must be filed before the regulatory payment period expires (article 38.1 of the Ley). And where the tax is settled by self-assessment (autoliquidación), which is the compulsory system in most regions, article 90.2 of the Reglamento requires it to be applied for within the first 5 months of that period. That is, 5 of the 6 months. If you reach the sixth month with your self-assessment in hand and have applied for nothing, the letter of the regulation rules your application out.

The Tribunal Supremo (the Spanish Supreme Court) has partly corrected that restriction. In judgment 1297/2025, of 15 October (cassation appeal 5673/2023, Third Chamber, Second Section), it held that article 90.2 of the Reglamento cannot cut by 1 month the period that article 62.1 of the Ley General Tributaria grants to pay a self-assessment, and it accepted an application filed together with a late self-assessment. In practice, missing the fifth month no longer necessarily closes the door.

Even so, the operational recommendation does not change: apply within the first 5 months. It is what the regulation in force says, it is what the managing offices apply and it is the only way to avoid having to argue about whether your application is admissible. A deferral you have to defend on appeal is no longer a solution, it is litigation.

Do not confuse the deferral with the prórroga (an extension of the filing deadline). The prórroga in article 68 of the Reglamento extends by another 6 months the period to file the documents, it is also applied for within the first 5 months, it is deemed granted if you get no answer within 1 month and it accrues late payment interest. They are different things and they are compatible: the prórroga gives you time to prepare the estate, the deferral gives you time to pay for it.

The first is the deferral of up to 1 year in article 38.1 of the Ley and article 82 of the Reglamento. It is granted where there is no liquidity in the estate and it is applied for in time. It accrues late payment interest. It is the simplest route and the least demanding, because the inheritance tax rules do not require you to provide security.

The second is splitting into a maximum of 5 yearly instalments (articles 38.2 of the Ley and 83 of the Reglamento). Same requirements, plus one: you must attach an undertaking to provide sufficient security covering the debt, the late payment interest and an extra 25% of the sum of the two. Final approval is conditional on that security actually being put in place.

The third is the deferral for unknown heirs (articles 38.3 of the Ley and 84 of the Reglamento). It is applied for by the administrators or holders of the estate assets when it is not yet known who the heirs are, and it lasts until they are known. It also requires an undertaking to provide security.

The fourth and the fifth are the special cases in article 39: transfer of a sole trader business, of a professional practice or of shareholdings exempt from the Impuesto sobre el Patrimonio (Spanish wealth tax), and transfer of the deceased's main home. Here the deferral is 5 years with no interest accruing, and once it ends the debt can be split into 10 half-yearly instalments at the statutory interest rate. It is by far the most favourable route.

The sixth is the splitting of life insurance paid out as an annuity (articles 39.4 of the Ley and 85 bis of the Reglamento): it is split over as many years as the annuity lasts, or 15 years if it is for life, with no security and no interest. In addition, if 3 months pass with no express decision, the application is deemed granted.

Underneath all of them there is always the safety net of the general regime: article 37 of the Ley refers to the Reglamento General de Recaudación (the Spanish general tax collection regulation), so even if you fit none of the special routes you can apply for an ordinary deferral under article 65 of the Ley General Tributaria, even once you are already in the enforcement period.

This is the case that solves the typical situation, that of someone who inherits their parents' flat and does not have the thousands of euros the comunidad autónoma is asking for. Article 39.3 of Ley 29/1987 extends to the deceased's main home the privileged regime that articles 39.1 and 39.2 provide for the family business.

Not every heir can apply for it. The law requires the person acquiring the home to be the spouse, an ascendant or a descendant of the deceased, or else a collateral relative over 65 who had lived with the deceased during the 2 years before the death. A nephew who inherits the flat and did not live there falls outside this route, although the other routes remain open to him.

The benefit is twofold. First, deferral during the 5 years following the day the payment period ends, with no interest payable during that period. Second, once those 5 years are over, splitting into 10 half-yearly instalments, this time at the statutory interest rate. In total, the debt can be stretched over a decade.

There is a limit worth knowing before you do the maths: the deferral does not cover the whole tax bill, only the proportional part of the tax debt corresponding to the value of the home over the total estate of each beneficiary (article 85.4 of the Reglamento). If the flat is 80% of what you inherit, 80% of your tax is deferred and the remaining 20% is paid within the deadline. The application must be accompanied by an undertaking to provide sufficient security.

A technical warning that most texts overlook: article 85 of the Reglamento still says 3 years and 7 half-yearly instalments, because it was not updated when the law moved to 5 years and 10 half-yearly instalments. The law prevails, as the higher-ranking and later rule. Managora bases the application on article 39 of the Ley and sets that reasoning out in writing in the application itself.

Deferring has a financial cost, except in the special cases of the main home, the business and life insurance annuities. The deferred debt accrues tax late payment interest, which in 2026 stands at 4.0625%, while the statutory interest rate remains at 3.25%. Interest runs from the day after the voluntary payment period ends until each granted instalment falls due, and it is paid together with each instalment (article 53 of the Reglamento General de Recaudación).

There is a little-used lever to bring that cost down: article 65.4 of the Ley General Tributaria provides that, where the whole of the deferred debt is secured by a joint and several guarantee from a credit institution, from a mutual guarantee company or by a surety insurance certificate, the interest charged is the statutory rate and not the late payment rate. On a debt over 5 years, the difference between 4.0625% and 3.25% is real money.

On the security: where it is required, it must cover the debt in the voluntary period, the late payment interest the deferral generates and 25% of the sum of those two items (article 48.2 of the Reglamento General de Recaudación, on the same terms as articles 83 and 84 of the inheritance tax Reglamento). With the application, an undertaking to provide it is enough. Once approval is notified, you have 2 months to formalise it; if you do not, the enforcement period starts the following day (articles 48.6 and 48.7).

The threshold that saves you the bank guarantee is €50,000. Orden HFP/583/2023, in force since 11 June 2023, raised to that figure the limit below which no security has to be provided for deferrals and instalment plans of devolved taxes whose collection is handled by the comunidades autónomas, replacing the old limit of €30,000. The amount is computed cumulatively, adding up all your outstanding debts with that administration, not only the one from the estate.

That threshold operates clearly in the general regime of article 65 of the Ley General Tributaria and several regions have also brought it into their own inheritance tax rules. Cataluña, for example, allows splitting into 5 yearly instalments with no security where the total debt does not exceed €50,000, and it also offers an exceptional deferral of up to 2 years with no security for lack of liquidity. Since the detail changes from one region to another, Managora checks the criteria of yours before deciding the route.

The application itself carries no tasa (official fee): there is no modelo 790 and nothing to pay to the administration for making it. What you take on is the deferral interest, the cost of the bank guarantee where applicable, and the service fee, which you can always see up to date on the service page at Managora.

The administration has 6 months to notify its decision. Once that period passes with no reply, the application is deemed refused for the purpose of appealing, although you can choose to wait for an express decision (article 52.6 of the Reglamento General de Recaudación). A refusal can be challenged by recurso de reposición (an appeal to the same office) or by an economic administrative claim.

Even if you are refused, having applied in time protects you. Filing the application in the voluntary period prevents the enforcement period from starting, although it does not stop interest accruing (article 65.5 of the Ley General Tributaria). That means the 5%, 10% or 20% surcharge in article 28 does not apply to you. If you are refused, the notification opens a new payment period, and only if you do not pay then either does enforcement begin.

If the deferral is granted and you then miss an instalment, article 54 of the Reglamento General de Recaudación applies: the unpaid part goes into the enforcement period with its surcharge and, depending on the case, the rest of the instalment plan can be declared due and the security enforced. It is not an irreversible situation, but it is best to tell us before the due date, not after.

And if the problem is that the 6-month deadline has already passed, the cost is fixed. A self-assessment filed late with no prior demand carries a surcharge of 1% plus another 1% for each complete month of delay, and of 15% plus interest if it is filed after 12 months (article 27.2 of the Ley General Tributaria). That surcharge is reduced by 25% if it is paid within the deadline, and the reduction is kept even when paying in instalments, provided the deferral was applied for when filing the late self-assessment and is granted with a bank guarantee or a surety insurance certificate (article 27.5). In other words, applying for the deferral at the same time as you regularise also saves surcharge.

We start with the number. We calculate the tax you owe in your region, we review the inventory of the estate and we determine whether or not there are sufficient readily realisable assets, which is the requirement that decides whether you fall into the special regime or have to go through the general one.

Then we choose the route. It is not a neutral choice: if the flat was the deceased's main home and you are the spouse, a child or a parent, the article 39.3 route gives you 5 years with no interest and nothing else comes close. If you do not fit, we compare the split into 5 yearly instalments with the 1-year deferral and with the general regime, and we tell you which works out better with your figures.

We prepare the application with its legal grounds, the inventory that evidences the lack of liquidity and, where appropriate, the undertaking to provide security, telling you exactly what to ask your bank for. We file it with the managing office of the competent region within the deadline and we follow it up until the decision.

If the estate has not been accepted yet and the deed is missing, we prepare it and we coordinate the signing before a notario (a Spanish notary public): it is a step in the procedure, not a job we hand back to you. And remember one useful effect of the deferral: article 33 of Ley 29/1987 makes access to public registers conditional on the document having been filed with the tax office, not on the tax having been collected. Filing and deferring lets you register the inheritance and, if you want, sell the property to pay afterwards.
