Deductions on ICIO (Tax on Construction, Installations and Works)
What is the ICIO and how does it affect your photovoltaic installation?
When you carry out a work in your home -such as installing solar panels- you must pay the Tax on Constructions, Installations and Works (ICIO). This municipal tax can increase the initial costs of the project, since it is calculated as a percentage of the material execution budget of the installation.
Did you know that you can save between 50% and 95%?
Many municipalities in Catalonia offer rebates of between 50% and 95% of the ICIO for self-consumption installations with solar panels. This means a direct saving in the procedures and helps to make the amortization of the installation even faster.
| Municipality | % ICIO rebate |
|---|---|
| Barcelona | 95% |
| Girona | 95% |
| Lleida | 95% |
| Tarragona | 50% |
| Sabadell | 95% |
| Mataró | 95% |
| Reus | 50% |
Important: These bonuses depend on the tax ordinances of each municipality and may change annually.
How to apply for the ICIO rebate?
- Apply for a minor construction permit or urban development permit.
- Submit budget and technical report of the photovoltaic project.
- Consult and take advantage of the bonus established in the current municipal ordinance.
- Apply for the bonus at the same time of applying for the license (in some municipalities it may be automatic).
At FOTOVOL we can help you to process this bonus in your municipality and reduce the administrative costs from the very first moment.

Reduced VAT for solar installations in Catalonia (2025)
In Catalonia, the reduced VAT rate of 10% remains in force in 2025 for certain solar installations, but only in specific cases. This tax benefit allows the cost of the investment to be reduced when certain conditions are met, as defined by the VAT regulations (Law 37/1992).
Cases in which the reduced VAT rate of 10% is applied
- First delivery of a new home:
If you buy a home directly from the developer or build one from scratch (new construction), and a solar installation is included, a reduced VAT rate of 10% is applied to the entire transaction. - Refurbishment or renovation of the usual dwelling:
If the photovoltaic installation is included in a refurbishment, and its cost does not exceed 40% of the total budget of the work, 10% is also applied.
What should you keep in mind?
- The reduced VAT does not apply if the solar installation is done on a stand-alone basis without major works.
- It must be a regular dwelling, not premises or an industrial facility.
- It is essential that the supplier invoices correctly by applying the reduced rate when applicable.
The reduced VAT rate is only applied in specific cases (first delivery of a home or renovations where the solar installation represents less than 40% of the total cost of the work). In the majority of standard installations on homes already built, the general rate of 21% applies.
Reduction in the urban development tax for the installation of solar panels
When applying for a minor works permit or a responsible declaration to install solar panels, many municipalities apply an urban planning fee. This fee covers the administrative and technical costs of the urban planning authorization.
Tax rebate or exemption
In Catalonia, many municipalities partially or totally subsidize this tax, especially in energy self-consumption projects. In some cases, the reduction can be up to 100%.
| Municipality | Urban development tax rebate |
|---|---|
| Barcelona | Up to 100%. |
| Girona | Up to 100%. |
| Sabadell | Partial (according to budget) |
| Reus | Partial |
Caution: This is not an automatic or uniform assistance. Each municipality has its own ordinances and requirements.
How to apply for the bonus?
- To present the request of work or responsible declaration.
- Indicate that it is a self-consumption solar installation.
- Consult if the city council foresees a reduction or exemption.
- In some cases, it is automatically applied when the documents are submitted.

How are solar panel subsidies taxed?
Subsidies received for the installation of solar panels are considered a capital gain and, for this reason, must be declared in the Personal Income Tax (IRPF). The amount to be declared will be the monetary amount of the subsidies obtained and must be included in the capital gains section of the period in which the payment was received.
How to maximize your savings? A real case in Barcelona
Let’s take the example of a single-family house in Barcelona with a self-consumption photovoltaic installation. The following subsidies are currently in force in this municipality:
- 50% IBI rebate for 3 years
- 95% ICIO rebate
- 95% reduction in the urban development tax
- 40% deduction in personal income tax, provided that energy efficiency requirements are met.
In this case, the initial cost of the installation was €7,500. Thanks to the available rebates and deductions, the direct savings exceeded €3,000, reducing the final investment to less than €4,500.
In addition to these initial savings, monthly electricity costs are practically eliminated, which further accelerates the return on investment.
Remember: these conditions are only available until the end of 2025 and may vary depending on the municipality. If you want to know how much you can save, contact the FOTOVOL team for free and personalized advice.
