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

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 |
| Alicante/Alacant | 50% | 5 | Tax ordinance |
| Castelló de la Plana | 50% | 10 | Tax ordinance |
| Elche/Elx | 50% | 3 | Tax ordinance |
| L'Eliana | 30% | 3 | Tax ordinance |
| Bétera | 40% | 3 | Tax ordinance |
Construction-tax (ICIO) bonuses by town
The construction tax (ICIO) is paid with the works licence or declaration. These towns reduce it on the solar part of the works:
| Town | ICIO bonus | Official source |
|---|---|---|
| València | 95% | Tax ordinance |
| Alicante/Alacant | 50% | Tax ordinance |
| Castelló de la Plana | 95% | Tax ordinance |
| L'Eliana | 95% | Tax ordinance |
| Bétera | 50% | Tax ordinance |
National income-tax deduction (works until 31 December 2026)
Across Spain (except the Basque Country and Navarre), you can deduct 40% of works that cut the home's non-renewable energy use by at least 30% or reach an A or B energy rating — at most €3,000. 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)

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.
