Marina Castell inherited her father's home in Jerez de la Frontera in April 2026. Her cousin Clara inherited her mother's flat the same month in a village in the Cádiz hills. The two homes have a similar cadastral value (the official value set by the Cadastre, Spain's property register for tax purposes), and both parents had owned them for more than twenty years. Clara has paid a token plusvalía (the plusvalía municipal is the local tax on the increase in value of urban land); Marina has been told of a four-figure sum. There is no mistake: each council decides whether to grant relief, how much and to whom, and decides it in a rule that almost nobody reads, its ordenanza fiscal, the council's tax bylaw.
What the law decides and what the council decides
The consolidated text of the Local Government Finance Act (TRLRHL) sets the framework and leaves almost everything else to each municipality. It starts with the basics: under its article 59.2, the plusvalía is a tax that councils "may establish". A municipality that has not approved the bylaw does not charge it.
Within the tax, the law allows the council to decide:
| Element | What the law sets | What the bylaw sets |
|---|---|---|
| Tax rate | A maximum (art. 108.1) | The rate, single or by periods |
| Coefficients for the objective method | Maximums by years of ownership (art. 107.4) | The specific coefficients |
| Reduction coefficient on the cadastral value | A ceiling (art. 107.2.a) | Whether it applies it, and to what extent |
| Reduction after a cadastral revaluation | Ceiling and duration (art. 107.3) | Whether it applies it, and with what percentages |
| Relief on family inheritances | Up to 95 % of the gross tax (art. 108.4) | Whether it exists, the percentage and the conditions |
| Relief for activities of municipal interest | Up to 95 % (art. 108.5) | Whether it exists; the full council declares it on application |
The exemptions in article 105, on the other hand, are set by the law and the council cannot remove them. Among them are handing over the main home in payment of the mortgage debt and transfers of that home in mortgage enforcement proceedings, subject to the requirements of article 105.1.c).
The relief that matters most: inheritances within the close family
Article 108.4 allows a relief of up to 95 % of the gross tax on transfers on death in favour of descendants and adopted children, spouses, ascendants and adoptive parents. Brothers and sisters, nephews and nieces, or unmarried partners are not on the legal list. Nor are gifts, because the paragraph refers only to transfers on death; we explain this in is plusvalía payable on a gift.
The 95 % is the ceiling, not the rule. A bylaw may set a single percentage, grade it by cadastral value, limit it to the deceased's main home, or not provide for it at all. That freedom explains the difference between Marina and her cousin.
How to find your municipality's bylaw
Article 17.4 of the Act requires the full text of tax bylaws and of their amendments to be published in the official gazette of the province, and they do not come into force until they are published. To find the one that affects you:
- Look on the council's website for the section on tax bylaws and for the one on the "tax on the increase in value of urban land".
- Check the date of the latest amendment published in the provincial gazette. Many were reformed at the end of 2021 to adapt to Royal Decree-law 26/2021 and have changed again since.
- If the management of the tax is delegated to the provincial council or to a provincial tax collection body, look there too: it usually publishes the forms and the instructions for the relief.
- Keep the version in force on the date of death, not today's.
Step 4 is the one most often forgotten. The tax falls due on the day of death, and the applicable bylaw is the one in force at that time.
Marina's figures, step by step
With the figures from her provisional assessment:
- Objective base for the land: 17,400 €.
- Gross tax with the rate in her municipality's bylaw: 4,350 €.
- If the bylaw granted the legal maximum to children: 4,350 × 0.05 = 217.50 €.
- If it only granted it when the cadastral value does not exceed a certain threshold and her father's does: 4,350 €, with no reduction.
- If it made it conditional on Marina keeping the property for a certain time and she sells before then: the council could claim back the relieved part, with the interest the bylaw lays down.
Scenarios 3 to 5 are assumptions to show the mechanism, not the content of any specific bylaw. What Marina pays depends only on what the Jerez bylaw in force in April 2026 says.
The requirements worth looking for in the text
When reading the bylaw, the useful questions are few and specific:
- Which relationships does it include? Does it mention spouses and registered partners?
- Is it limited to the deceased's main home? How is that proved: the padrón (the municipal register of inhabitants), living together, bills?
- Is there a cadastral value ceiling above which the relief falls or disappears?
- Does it require the property to be kept for a number of years? What happens if it is sold before then?
- Does it have to be applied for? Must it be claimed within the six-month period for filing the declaration?
You can send us the cadastral reference, the death certificate and the inheritance deed with the plusvalía form. We find the bylaw applicable on the date and check whether the relief fits.
When the bylaw requires the relief to be applied for, it is not granted automatically. If it also ties the application to the filing period, filing late can cost the whole relief, which in an inheritance usually weighs much more than the surcharge for lateness. And if it requires the property to be kept, selling too soon can mean having to pay it back. We cannot assure you that a council will accept a late application.
If the problem is not the relief but the base
Sometimes the difference between two municipalities lies not in the relief but in the base. The reduction coefficient and the reduction after a cadastral revaluation lower the value of the land on which the objective method is calculated, and they do not depend on the family relationship. And whatever the bylaw says, any heir can ask to be taxed on the actual increase if it is lower, or prove that there was no increase. Both routes are covered in objective or actual method and in how the value of the land is worked out.
For the inheritance as a whole, with its deadline and its taxpayers, the reference is who pays the plusvalía on an inheritance, and the guide on plusvalía on inheritances and gifts completes the picture with Inheritance Tax.
The Salama Tax page devoted to the municipal plusvalía explains the tax and the documents needed in each situation, including those the reliefs require.
