Modelo 560 — Special Tax on Electricity Spain

Modelo 560 — Special Tax on Electricity Spain (Impuesto Especial sobre la Electricidad — IEE) is the periodic tax declaration required under Ley 38/1992 de Impuestos Especiales (LIIEE) arts. 64–79 and Real Decreto 1165/1995 (Reglamento de Impuestos Especiales — RIIEE) arts. 145–162, by which electricity suppliers (comercializadoras de energía eléctrica), distributors, and self-consumers (autoconsumidores) of electricity must declare and pay the special excise duty (impuesto especial) levied on the supply and self-consumption of electrical energy in Spain. The Impuesto Especial sobre la Electricidad is an indirect tax forming part of Spain's special taxes framework (impuestos especiales de fabricación) under the broader EU excise duty harmonisation framework established by Council Directive 2003/96/EC (Energy Taxation Directive).

The IEE applies to the supply of electricity for consumption in Spain by any person who acquires electricity for their own use (including industrial self-consumption and renewable energy self-consumption), and to electricity consumed by the generators and operators themselves. The taxable event (hecho imponible) under LIIEE art. 64 is the supply of electrical energy to final consumers by authorised electricity suppliers operating under the licences issued by the Comisión Nacional de los Mercados y la Competencia (CNMC) or, in the case of self-consumption, the drawing of electricity from generation facilities.

The tax rate applicable to the IEE is established by LIIEE art. 69: the general rate is 5.11269632% applied to the value of electrical energy supplied (base imponible), calculated on the total billing amount excluding VAT but including the system access charges (peajes de acceso) and network charges (cargos de red) set by the Secretaría de Estado de Energía under the Ministerio para la Transición Ecológica y el Reto Demográfico (MITERD). This structure means the IEE base includes both energy cost and regulated network access charges.

The IEE was substantially restructured by Real Decreto-Ley 17/2021, de 26 de octubre, which temporarily reduced the IEE rate to 0.5% — and subsequently to 0.5% under various emergency measures through 2022 and 2023 — in response to the European energy crisis and high electricity prices. Subsequent legislation including Real Decreto-Ley 8/2023 and Real Decreto-Ley 4/2024 further modified rates and exemptions. Operators must verify the currently applicable rate with the AEAT's published tax tables before completing Modelo 560.

Exemptions from the IEE under LIIEE arts. 64–66 include electricity consumed in electrolytic processes for the production of aluminium, chlorine, alkali metals, and other industrial chemicals; electricity generated and consumed by high-efficiency combined heat and power (CHP) plants under specific output thresholds; electricity used in railway traction (tracción ferroviaria); and electricity consumed in the Canary Islands, Ceuta, and Melilla, which have their own special tax regimes under LIIEE.

Modelo 560 must be filed quarterly by most operators, though large enterprises (grandes empresas) and certain high-volume operators file monthly. The declaration summarises the total electricity supplied or self-consumed during the period, the applicable rates, total IEE due, applicable exemptions and reductions, and the net tax payable. Filing is made through the AEAT Sede Electrónica using a certificado digital or Cl@ve PIN, with concurrent electronic payment through the Spanish banking system or direct bank debit (domiciliación bancaria).

Modelo 560 — Special Tax on Electricity Spain must be filed by all entities authorised to supply electricity to final consumers under licences granted by the Comisión Nacional de los Mercados y la Competencia (CNMC), including comercializadoras de electricidad (licensed retail electricity suppliers), distribuidoras (distribution network operators) when they supply electricity directly, and any person who generates and self-consumes electrical energy above the exemption thresholds set by LIIEE art. 64.

Modelo 560 is required for comercializadoras de electricidad — the licensed retail electricity suppliers such as Iberdrola Clientes, Endesa Energía, Naturgy Iberia, and smaller independent suppliers — who bill final consumers (households, businesses, industries) for electricity supply. These entities act as IEE taxpayers (sujetos pasivos) under LIIEE art. 68, collecting the tax from consumers as part of their electricity bills and remitting it to the AEAT through periodic Modelo 560 declarations.

Modelo 560 is required for industrial self-consumers (autoconsumidores industriales) who generate electricity from their own facilities — solar panels, wind turbines, or CHP plants — and consume it on-site. Under LIIEE art. 64 and the regulations introduced by Real Decreto 244/2019 on self-consumption and Real Decreto-Ley 23/2020, self-consumed electricity above 100 kW of installed generation capacity is subject to IEE, though specific exemptions and reductions apply depending on the technology and consumption profile.

Modelo 560 is required when a company operating in the Peninsular Spain or the Balearic Islands receives electricity under a direct line (línea directa) from a generator — as permitted under Ley 24/2013 del Sector Eléctrico — and the supplying entity is not a licensed comercializadora. In this case, the recipient company may be deemed the IEE taxpayer.

Modelo 560 is not required by final consumers (consumers who are not electricity suppliers or self-consumers above thresholds) — they pay the IEE embedded in their electricity bills from their comercializadora. Modelo 560 is also not applicable to entities operating exclusively in the Canary Islands, Ceuta, or Melilla, which have separate special tax regimes under LIIEE arts. 64–66 and separate declaration forms.

Modelo 560 is required when a company operating a renewable energy park (parque eólico, planta solar fotovoltaica) generates electricity and either self-consumes a portion on-site or supplies directly to industrial clients under a power purchase agreement (PPA — contrato de compraventa de electricidad). In these cases the energy producer may qualify simultaneously as an electricity supplier and a self-consumer, requiring careful identification of which CUPS (Código Universal del Punto de Suministro) reference points are subject to IEE. The Comisión Nacional de los Mercados y la Competencia (CNMC) assigns CUPS codes and maintains the registry of electricity supply points through which IEE liability is tracked.

Modelo 560 is required when a retailer or industrial operator with on-site CHP (combined heat and power — cogeneración) equipment consumes the electricity generated in excess of the efficiency thresholds that would qualify for IEE exemption under LIIEE art. 64.4. The MITERD's certification of CHP efficiency under Real Decreto 616/2007 is a prerequisite for claiming the exemption — without a valid efficiency certificate, full IEE applies to all CHP-generated electricity consumed on-site.

Under Spanish law, the Constitución Española 1978 is the supreme law. The Código Civil governs contractual obligations under Article 1255 (libertad de pactos). The AEAT administers taxation. The Juzgados de Primera Instancia have general civil jurisdiction. The Ley 39/2015 governs administrative procedure. The LOPDGDD (LO 3/2018) and RGPD govern data protection through the Agencia Española de Protección de Datos (AEPD).

A correctly completed Modelo 560 — Special Tax on Electricity Spain under LIIEE arts. 64–79 must include the following mandatory sections and data elements.

Declarant Identification: NIF (Número de Identificación Fiscal) of the electricity supplier or self-consumer, full legal or business name, CAE (Código de Actividad y Establecimiento) assigned by the AEAT's Impuestos Especiales administration for the relevant electricity supply or generation establishment, and the reporting period (monthly or quarterly).

Taxable Supply Data: Total kilowatt-hours (kWh) of electricity supplied to final consumers during the period, broken down by tariff category and consumer type — domestic consumers, commercial consumers, industrial consumers, and exempt consumers. The billing amount (importe facturado) for each category forms the tax base (base imponible) for IEE purposes, excluding VAT but including regulated network charges.

Applicable Tax Rate: The IEE rate applicable to the reporting period — which may vary due to emergency legislation reducing the rate below the standard 5.11269632% — must be confirmed from the AEAT's published tables before completing Modelo 560. Different rates may apply to different consumption categories if rate exemptions or reductions are in force.

Exemptions and Reductions: Electricity supplied to exempt consumers (electrolytic processes, railway traction, CHP plants meeting efficiency thresholds, diplomatic missions) must be separately identified with the applicable exemption code under LIIEE art. 64. Documentary proof of the consumer's exempt status (certificate from CNMC, DGT ruling, or customs/excise authorisation) must be maintained in the operator's records for AEAT inspection.

Self-Consumption Data: Self-consumers filing Modelo 560 must declare the total self-consumed electricity, the installed generation capacity, the technology type (solar photovoltaic, wind, CHP, etc.), and any applicable exemption or reduction under LIIEE and Real Decreto 244/2019. Net generation after grid injection (surplus sold to the network) is excluded from the self-consumption IEE base.

Tax Calculation and Payment: Total IEE payable (cuota íntegra) is calculated as the taxable base multiplied by the applicable rate, less any allowable credits or deductions. The resulting net amount (cuota diferencial) must be paid simultaneously with the Modelo 560 filing through the AEAT's electronic payment system or bank transfer. Large enterprises must use direct bank debit (domiciliación).

Amendment Procedure: Errors in filed Modelo 560 declarations are corrected through a declaración complementaria or sustitutiva filed through the AEAT Sede Electrónica, referencing the original filing's justificante number. Additional IEE liability revealed by the amendment must be paid with applicable late-payment interest (intereses de demora).

Forms-legal.com provides this Modelo 560 template as an operational reference. Electricity suppliers and large industrial self-consumers should engage a specialist in impuestos especiales (excise duty specialist) or accredited asesor fiscal familiar with energy sector regulations to confirm correct rate application and exemption documentation. The rate volatility during 2021–2024 makes historical rate verification essential for prior-period declarations.

Rate History and Documentation: Given the repeated emergency rate modifications since 2021, operators preparing Modelo 560 for prior periods must maintain a rate application log identifying the specific Royal Decree or Real Decreto-Ley that established the rate for each billing period. The AEAT's Departamento de Aduanas e Impuestos Especiales publishes rate tables on the AEAT website, and the CNMC publishes complementary tariff regulatory orders that affect the IEE base calculation. Failure to apply the correct rate for the relevant period constitutes a filing error subject to LGT sanctions even if corrected voluntarily.

Integration with Electricity Market Billing Systems: Comercializadoras de electricidad must confirm their billing systems (sistemas de facturación eléctrica) are configured to calculate IEE automatically by billing period, applying the rate in force for each invoice date. The CUPS (Código Universal del Punto de Suministro) must be correctly assigned to each consumption point, and IEE amounts must be itemised separately on invoices issued to business customers under Real Decreto 1619/2012 (Reglamento de Facturación). Correct invoice itemisation is essential for business customers who need to account for IEE as a non-deductible energy cost in their corporate income tax returns.

Under LIIEE arts. 64–79, the IEE is administered by the AEAT's Departamento de Aduanas e Impuestos Especiales. The CNMC regulates electricity market operators and licensing. The Secretaría de Estado de Energía (MITERD) sets network tariffs. Council Directive 2003/96/EC governs EU energy taxation harmonisation. The Tribunal Económico-Administrativo Central (TEAC) hears IEE administrative appeals.
