Solar panels on a home in the Valencian Community can be cheaper than the invoice says: the regional government, many town halls and the national tax agency each reduce a different tax. This article puts them in one place, with the official source of each rule. ## Regional income-tax deduction **40% of the amount invested** in a self-consumption installation at your main home can be deducted from the regional part of your income tax (20% for other homes), on up to €8,800 of spending per home and year. Homes in the Comunitat Valenciana: 40% for your main residence, 20% for other homes. Installation registered with the regional administration. **Conditions** - The installation must be registered in the Valencian self-consumption registry - Payment by card, bank transfer, nominative cheque or bank deposit (not cash) - The home is not used for an economic activity; subsidised amounts are excluded - Enough regional income tax due (four-year carry-forward available) - Compatibility with the national IRPF deduction on the same invoice should be confirmed with a tax adviser Official source: [Agencia Tributaria — Manual Renta 2025, Comunitat Valenciana: instalaciones de autoconsumo (Ley 13/1997, art. 4.Uno.o)](https://sede.agenciatributaria.gob.es/Sede/ayuda/manuales-videos-folletos/manuales-practicos/irpf-2025-deducciones-autonomicas/comunitat-valenciana/cantidades-invertidas-instalaciones-autoconsumo-generacion-termica.html) ## Property-tax (IBI) bonuses by town Several town halls reduce the property tax (IBI) for a few years after you install solar. The bonus is a share of your IBI bill; some towns also cap it. You request it from the town hall with the installation certificate and the invoices. | Town | IBI bonus | Years | Official source | | --- | ---: | ---: | --- | | València | 50% | 4 | [Tax ordinance](https://sede.valencia.es/sede/descarga/doc/DOCUMENT_1_20250009476596) | | Alicante/Alacant | 50% | 5 | [Tax ordinance](https://www.alicante.es/sites/default/files/documentos/202512/ordenanza-ibi-dic2025.pdf) | | Castelló de la Plana | 50% | 10 | [Tax ordinance](https://www.castello.es/documents/35637/5037693/Ordenanza+Fiscal+IBI+2026.pdf/2c766195-3997-d259-15c4-5e7d5293cc04?t=1767873142317) | | Elche/Elx | 50% | 3 | [Tax ordinance](https://www.elche.es/download/ordenanzas-fiscales-del-ajuntament-delx-para-el-ano-2025/) | | L'Eliana | 30% | 3 | [Tax ordinance](https://www.leliana.es/sites/www.leliana.es/files/IBI_lEliana.pdf) | | Bétera | 40% | 3 | [Tax ordinance](https://betera.sedelectronica.es/preview-document/bad44c78-a2db-4ea8-b34b-d1be307bfbab) | ## Construction-tax (ICIO) bonuses by town The construction tax (ICIO) is paid with the works licence or declaration.

Solar can qualify when the energy certificates before and after the works show the improvement. **Conditions** - An energy performance certificate issued before the works (within the previous 2 years) and another after them - The certificates must show at least a 30% cut in non-renewable primary energy use, or an A/B rating - Works completed by 31 Dec 2026 and the post-works certificate issued before 1 Jan 2027 - Enough income tax due to absorb the deduction; subsidised amounts are excluded from the base - You pay income tax under the common state regime (not in País Vasco or Navarra, which have their own) Official source: [Agencia Tributaria — Deducción por obras para la mejora en el consumo de energía primaria no renovable (Ley 35/2006, DA 50ª.2)](https://sede.agenciatributaria.gob.es/Sede/vivienda-otros-inmuebles/deducciones-obras-mejora-eficiencia-energetica-viviendas/deduccion-obras-mejora-consumo-energia-renovable.html) ## Before you sign - Most bonuses are claimed by you, after the installation, with the installation certificate and the invoices. - The Valencian deduction does not accept cash payments: pay by card, bank transfer, nominative cheque or bank deposit. - For the national deduction, order the first energy certificate before the works start. - Rules change every year: open the official source before relying on a figure.

Possibly, but it has not been confirmed for the same invoice: check with a tax adviser before counting on both. Subsidised amounts are excluded from both deductions. ### Which towns in the Valencian Community reduce the IBI for solar? In our data: València, Alicante/Alacant, Castelló de la Plana, Elche/Elx, L'Eliana, Bétera. Each town sets its own share, duration and caps in its tax ordinance. ### Do I need to register the installation? Yes. The Valencian deduction requires the installation to be registered in the regional self-consumption registry. ## Sources - [Agencia Tributaria — Manual Renta 2025, Comunitat Valenciana: instalaciones de autoconsumo (Ley 13/1997, art. 4.Uno.o)](https://sede.agenciatributaria.gob.es/Sede/ayuda/manuales-videos-folletos/manuales-practicos/irpf-2025-deducciones-autonomicas/comunitat-valenciana/cantidades-invertidas-instalaciones-autoconsumo-generacion-termica.html) - [Agencia Tributaria — Deducción por obras para la mejora en el consumo de energía primaria no renovable (Ley 35/2006, DA 50ª.2)](https://sede.agenciatributaria.gob.es/Sede/vivienda-otros-inmuebles/deducciones-obras-mejora-eficiencia-energetica-viviendas/deduccion-obras-mejora-consumo-energia-renovable.html) - [Ajuntament de València — Ordenanza fiscal reguladora del IBI, art. 15](https://sede.valencia.es/sede/descarga/doc/DOCUMENT_1_20250009476596) - [Ayuntamiento de Alicante — Ordenanza fiscal del IBI (texto dic. 2025), art. 4º.2.2](https://www.alicante.es/sites/default/files/documentos/202512/ordenanza-ibi-dic2025.pdf) - [Ajuntament de Castelló de la Plana — Ordenanza fiscal IBI 2026, art. 13](https://www.castello.es/documents/35637/5037693/Ordenanza+Fiscal+IBI+2026.pdf/2c766195-3997-d259-15c4-5e7d5293cc04?t=1767873142317) - [Ajuntament d'Elx — Ordenanzas fiscales 2025, IBI bonificación 5ª](https://www.elche.es/download/ordenanzas-fiscales-del-ajuntament-delx-para-el-ano-2025/) - [Ajuntament de l'Eliana — Ordenanza fiscal IBI, art. 3.(VI)c](https://www.leliana.es/sites/www.leliana.es/files/IBI_lEliana.pdf) - [Ajuntament de Bétera — OF nº 01 IBI (mod. 2024), art. 14](https://betera.sedelectronica.es/preview-document/bad44c78-a2db-4ea8-b34b-d1be307bfbab) - [Ajuntament de València — Ordenança fiscal ICIO (text consolidat 2025), art. 7.B](https://sede.valencia.es/sede/descarga/doc/DOCUMENT_1_20250008120705) - [Ayuntamiento de Alicante — Ordenanza fiscal ICIO, art. 5º](https://www.alicante.es/sites/default/files/documentos/202312/ordenanza-impuesto-construcciones-instalaciones-y-obras.pdf) - [Ajuntament de Castelló de la Plana — Ordenanza fiscal ICIO (vigente desde 1-1-2022), art. 5.3](https://www.castello.es/documents/35637/91232/icio_2022_cas.pdf/a9d9954a-a521-cd5e-cc8c-7990a3abe74a?t=1647290989888) - [Ajuntament de l'Eliana — Ordenanza fiscal ICIO (2026)](https://www.leliana.es/sites/www.leliana.es/files/files/ordenances/2026/09-04-26%20IMPUESTO%20DE%20CONSTRUCCIONES%20INSTALACIONES%20Y%20OBRAS%20%28ICIO%29.pdf) - [Ajuntament de Bétera — Ordenanza fiscal ICIO, art. 7.2](https://betera.sedelectronica.es/preview-document/3e945a4f-e3e3-44aa-87d0-1ec014f15e04)
