Gift Tax Declaration (Modelo 651) Spain

The Gift Tax Declaration (Modelo 651) Spain is the official self-assessment form used to declare and pay the Impuesto sobre Sucesiones y Donaciones (ISD) on inter vivos donations — gifts of money, property, or other assets received from a living person — governed by Ley 29/1987, de 18 de diciembre, del Impuesto sobre Sucesiones y Donaciones and its implementing Reglamento approved by Real Decreto 1629/1991, de 8 de noviembre. Article 31 of the ISD Reglamento establishes the specific rules governing the taxation of inter vivos acquisitions, distinguishing the Modelo 651 from the Modelo 650 (used for inheritances) and the Modelo 652 (used for life insurance proceeds).

The Impuesto sobre Sucesiones y Donaciones is a direct, personal, and progressive tax levied on the net increase in wealth acquired gratuitously by natural persons. The taxable event (hecho imponible) under Article 3.1.b) of Ley 29/1987 is the acquisition of property and rights by gift or any other gratuitous inter vivos legal transaction. The tax base (base imponible) under Article 9 is the net value of the goods and rights acquired — their market value (valor real) minus any deductible debts and charges.

Tax rates under ISD range from 7.65% to 34% under the State tariff established in Article 21 of Ley 29/1987, applied to brackets of taxable base. However, Spanish Autonomous Communities (Comunidades Autónomas) have broad regulatory powers over ISD under Ley 22/2009, de 18 de diciembre, de financiación de las Comunidades Autónomas — they may modify rates, establish reductions, and grant bonifications that can drastically reduce or even eliminate the tax for certain family relationships. For instance, Madrid grants a 99% bonification on gifts between direct relatives under their regional legislation, while Andalucía has also introduced significant reductions. The applicable law is that of the Autonomous Community where the donor has their fiscal residence (residencia fiscal) for most donations.

The aplicable reduction (reducción) system under Article 20 of Ley 29/1987 grants significant tax reliefs based on the kinship group (grupo) between donor and recipient: Group I (descendants under 21), Group II (spouses and direct relatives), Group III (second-degree collateral relatives), and Group IV (more distant relatives and unrelated persons). Additional reductions apply for persons with disabilities (discapacidad) under Article 20.2.a), and for business assets (empresa individual, negocio profesional, or participaciones en entidades) under Article 20.6, provided conditions on maintenance of the gift for 10 years are met.

The Modelo 651 must be filed within 30 working days (días hábiles) from the date of the donation act, pursuant to Article 67.1 of the ISD Reglamento. The filing is made before the Consejería de Hacienda or Agencia Tributaria of the competent Autonomous Community — generally where the donee has their habitual residence (residencia habitual). Donations formalised before a Spanish notary (notario) in a public deed (escritura pública) trigger immediate notification from the notary to the tax authorities, but the donee must still file the Modelo 651 and pay any tax due within the statutory period.

For donations of real estate (bienes inmuebles) located in Spain, the Junta de Castilla y León, Generalitat de Catalunya, Comunidad de Madrid, and other communities operate their own online platforms for Modelo 651 submission. Donations involving foreign assets or non-resident donors may also trigger reporting obligations under the Modelo 720 (foreign assets declaration) if the recipient becomes the holder of foreign assets exceeding €50,000 in any category.

A Gift Tax Declaration Modelo 651 Spain is required whenever a natural person receives a donation, gift, or gratuitous inter vivos transfer of property, rights, or money from another person — whether from a family member or an unrelated third party — with a value that generates an ISD taxable event under Ley 29/1987 Article 3.1.b).

Modelo 651 is needed when parents gift money or real estate to their children — one of the most common triggers — including partial transfers of a family business, gifting shares (participaciones) in a Sociedad Limitada under Ley 29/1987 Article 20.6 with application for the empresa familiar reduction, or transferring bank deposits exceeding the minimum exemption threshold established by the applicable Autonomous Community.

The declaration is required when a spouse or registered civil partner (pareja de hecho) receives property through a donation agreement — the applicable reduction and tax rate depend on the Autonomous Community of the donee's fiscal residence, as community rules vary widely from near-total exemption (Madrid, Andalucía) to standard State rates.

Modelo 651 must be filed when a person receives a gratuitous forgiveness of debt (condonación de deuda) from another natural person, as Article 12 of Ley 29/1987 treats debt forgiveness as a taxable donation to the extent of the forgiven amount, valued at market rates.

The form is required when a donor makes a gift of participation units (participaciones sociales) in a Spanish company to a family member — the empresa familiar reduction under Article 20.6 of Ley 29/1987 may reduce the taxable base by 95% if the conditions on percentage ownership, active management, and 10-year retention are satisfied.

Modelo 651 is needed in the context of a pacto sucesorio (succession agreement) under civil law of certain Autonomous Communities (Cataluña, Galicia, País Vasco, Navarra, Aragón, Baleares) — these agreements can anticipate inheritance and may be subject to ISD treatment as donations under regional laws.

The declaration is also required when a non-resident in Spain receives a donation of assets located in Spain — under Article 7 of Ley 29/1987, non-residents are subject to ISD on Spanish-sited assets received as donations, and the filing is made before the Agencia Tributaria (AEAT) Oficina Nacional de Gestión Tributaria rather than the Autonomous Community.

A complete Modelo 651 Gift Tax Declaration Spain under Ley 29/1987 and RD 1629/1991 must accurately record the following elements to achieve a valid self-assessment and avoid penalties from the Agencia Tributaria or the competent Comunidad Autónoma tax authority.

Identification of Parties: Full name, DNI/NIE, and fiscal address of the donee (donatario) — the person receiving the gift and liable for the tax. Full name, DNI/NIE or NIF, and address of the donor (donante). Where a legal entity makes a gift, the entity's NIF and Registro Mercantil details are required, though note that donations from legal entities to natural persons may be subject to IRPF treatment rather than ISD under Article 12.2 of the Ley del IRPF.

Description and Valuation of the Gift: Precise description of the donated asset — for real estate, the cadastral reference (referencia catastral), surface area, location, and registration data from the Registro de la Propiedad. For shares in companies, the company name, NIF, number of participaciones, nominal value, and computed real value per the rules of Article 16 of Ley 29/1987. For cash donations, the amount in euros and the source account. The declared value must equal the real market value (valor real de mercado) — understating value triggers inspection by the Comprobación de Valores procedure under Ley 58/2003 General Tributaria Article 57.

Date and Form of Donation: The date on which the donation was formalised — for notarised donations, the date of the escritura pública before the notario; for private document donations, the date of the document. The method of formalisation affects timing of the 30-day filing deadline under Article 67 of RD 1629/1991.

Kinship Group (Grupo de Parentesco): The relationship between donor and donee, determining applicable pre-existing patrimony multiplier (coeficiente multiplicador) and reductions under Article 20 of Ley 29/1987. Groups I through IV carry different base reductions — €15,956.87 for Group II, €7,993.46 for Group III, and no state reduction for Group IV, before any autonomous community additions.

Pre-existing Patrimony of the Donee: The total value of the donee's pre-existing net patrimony (patrimonio preexistente) as declared — classified into four bands under the State tariff. The pre-existing patrimony affects the coeficiente multiplicador applied to the calculated tax quota under Article 22 of Ley 29/1987, potentially increasing the effective rate by up to 2.4 times for wealthier recipients.

Applicable Reductions: Identification of all reductions claimed — disability reduction (minusvalía) under Article 20.2.a), empresa familiar reduction under Article 20.6, principal residence reduction in certain communities, and any regional reductions specific to the donee's Autonomous Community. Each claimed reduction must be separately itemised and its legal basis cited.

Autonomous Community Regulations: Specification of the competent Autonomous Community — the fiscal residence (residencia fiscal habitual) of the donee for most asset types. Regional bonifications and reductions — such as Madrid's 99% bonification under Decreto Legislativo 1/2010 — must be separately computed and applied after the State quota calculation.

Payment Method and Deferral: ISD can be paid in cash, by bank transfer, or through a financial institution. In certain circumstances, the tax authority may grant deferral (aplazamiento) or fractioned payment (fraccionamiento) under Articles 65 and 82 of Ley 58/2003 General Tributaria, subject to interest accrual at the legal rate.

Forms-legal.com provides this Modelo 651 Gift Tax Declaration Spain template as a practical starting point for the self-assessment process. Every donation of significant value should be reviewed by a qualified gestor-administrativo, asesor fiscal, or abogado tributarista to confirm the applicable community rules, available reductions, and accurate valuation methods, particularly for complex assets such as unlisted company shares, agricultural land, or business assets qualifying for the empresa familiar exemption under Ley 29/1987.

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).
