What Is a New Vehicle Tax (ISAN) Declaration Mexico (Declaración del Impuesto sobre Automóviles Nuevos)?

The New Vehicle Tax (ISAN) Declaration Mexico (Declaración del Impuesto sobre Automóviles Nuevos) is the official tax payment instrument required for the transfer and importation of new automobiles in Mexico under the Ley Federal del Impuesto sobre Automóviles Nuevos (Ley Federal del ISAN), published in the Diario Oficial de la Federación on 30 December 1996 and most recently reformed to align with the fiscal federalism framework under the Ley de Coordinación Fiscal. Article 1 of the Ley Federal del ISAN establishes that the tax applies at the moment the first transfer of a new automobile is made by the manufacturer (fabricante), assembler (ensamblador), distributor (distribuidor autorizado), or importer (importador) to the final purchaser or to any commercial intermediary in the domestic market, as well as at the moment of importation of a new automobile for use in Mexican territory.

ISAN is a federal tax (impuesto federal) coordinated through the Sistema Nacional de Coordinación Fiscal — under the Ley de Coordinación Fiscal, states that adhere to the coordination system agree not to levy their own vehicle acquisition taxes in exchange for receiving ISAN participaciones (revenue-sharing transfers). This coordination means that ISAN operates as the sole first-acquisition vehicle tax at both federal and effectively state levels across all adhering states, avoiding double taxation on new automobile purchases.

The tax base (base gravable) is defined in Article 2 of the Ley Federal del ISAN as the manufacturer's or importer's price to the final consumer (precio de enajenación al consumidor), excluding IVA (Impuesto al Valor Agregado) but including all accessories, optional equipment, and freight charges included in the sale price. For importers, the tax base is the customs value (valor en aduana) determined under the Ley Aduanera and the Código Fiscal de la Federación, plus applicable tariffs (aranceles) and other importation costs, excluding IVA.

ISAN rates (tasas) are progressive, established in Article 3 of the Ley Federal del ISAN, ranging from a base rate for lower-value vehicles up to higher rates for luxury vehicles (automóviles de lujo) exceeding price thresholds updated annually through the Resolución Miscelánea Fiscal. Electric vehicles (vehículos eléctricos) and hybrid vehicles meeting specified technical standards benefit from preferential ISAN rates or complete exemptions under amendments introduced to promote environmentally sustainable transport — the specific applicable rates for each vehicle category and price bracket are published in the Resolución Miscelánea Fiscal each fiscal year.

The ISAN Declaration is filed electronically through the SAT portal (sat.gob.mx) and through the specialized e-ISAN module used by manufacturers and authorized distributors who file on a monthly or event-by-event basis. Payment is made through authorized banking institutions (instituciones de crédito autorizadas) or through the SAT's electronic payment portal, generating a línea de captura and an acuse de recibo with a folio number confirming payment receipt. The Servicio de Administración Tributaria administers ISAN collection nationally, and the proceeds are distributed to states through the participaciones fiscales mechanism under the Ley de Coordinación Fiscal.

The automotive sector in Mexico operates under additional regulatory frameworks that interact with ISAN obligations. The Secretaría de Economía administers import quotas and tariff classifications under the Tarifa de la Ley de los Impuestos Generales de Importación y de Exportación (TIGIE), which determines the applicable fracción arancelaria for each vehicle type and triggers preferential tariff rates under free trade agreements. The T-MEC (Tratado entre México, Estados Unidos y Canadá) replaced NAFTA/TLCAN in 2020 with new rules of origin requirements for motor vehicles, requiring regional value content and specific labour value content thresholds for vehicles to qualify for zero tariff treatment under Annex 4-B of the T-MEC. These trade compliance considerations affect both the ISAN tax base calculation and the total landed cost for imported vehicles, making ISAN declaration preparation an interdisciplinary task requiring both fiscal and trade compliance expertise.

When Do You Need a New Vehicle Tax (ISAN) Declaration Mexico (Declaración del Impuesto sobre Automóviles Nuevos)?

The ISAN Declaration Mexico is required in three primary circumstances defined by the Ley Federal del ISAN: domestic first-transfer (enajenación), importation (importación), and in certain circumstances involving new vehicles used by manufacturers themselves before commercial transfer.

The declaration is needed when a manufacturer (fabricante) or assembler (ensamblador) of automobiles registered with the SAT as a causante del ISAN transfers a new vehicle for the first time to a distributor (distribuidor autorizado) or directly to the end consumer. Under Article 1 Fracción I of the Ley Federal del ISAN, the tax event (hecho imponible) occurs at the moment of the first enajenación — typically corresponding to the invoice date (fecha de factura) issued by the manufacturer or authorized distributor under the CFDI (Comprobante Fiscal Digital por Internet) system.

The declaration is needed when any person or entity — whether a commercial importer (importador persona moral) or an individual (importador persona física) — imports a new automobile into Mexico for use in Mexican territory under Article 1 Fracción II of the Ley Federal del ISAN. The ISAN must be paid at the aduana (customs office) prior to the vehicle being released from customs clearance (despacho aduanero), alongside the applicable general import tariff (arancel de importación) and IVA. An official customs declaration (pedimento de importación) issued under the Ley Aduanera serves as the primary import document, and the ISAN payment is recorded in the pedimento.

The ISAN Declaration is also required when a manufacturer or assembler uses a new automobile for company purposes (uso propio) before any transfer — Article 1 Fracción III of the Ley Federal del ISAN treats this as a taxable event equivalent to a transfer to oneself, triggering ISAN liability at the moment the vehicle is assigned to company use.

The declaration is not required — and ISAN is not payable — for used vehicle (vehículo usado) transfers, since ISAN only applies to the first transfer of new vehicles. It is also not required for transfers between manufacturers and their authorized distributors that qualify as intermediate commercial transactions rather than final consumer transfers, though the applicable rules and documentation requirements for claiming distributor-level treatment must be reviewed carefully against the SAT's published criteria to avoid misclassification. Diplomatic exemptions (exenciones diplomáticas) apply to vehicles acquired by foreign diplomatic missions under the Ley sobre Inmunidades de las Misiones Diplomáticas.

For dealerships (concesionarios automotrices) participating in the Asociación Mexicana de Distribuidores de Automotores (AMDA) network, ISAN obligations arise at the point of delivery of the vehicle to the consumer under the terms of the concession agreement with the manufacturer. Fleet sales (ventas a flotillas) to corporate buyers are subject to ISAN at the same rates as retail transactions — there are no ISAN volume discounts for large fleet purchases, though ISR deductibility rules under LISR Article 36 may provide income tax benefits for fleet vehicle acquisitions.

What to Include in Your New Vehicle Tax (ISAN) Declaration Mexico (Declaración del Impuesto sobre Automóviles Nuevos)

A complete ISAN Declaration Mexico under the Ley Federal del ISAN must include the following elements to be accepted by the SAT and to comply with the coordination requirements under the Ley de Coordinación Fiscal.

Taxpayer Identification: Full legal name (razón social) of the manufacturer, distributor, or importer filing the declaration, together with their RFC (Registro Federal de Contribuyentes) assigned by the SAT. For manufacturers and distributors filing monthly consolidated ISAN returns, the RFC is the principal identifier linking each month's ISAN declaration to the entity's broader federal tax compliance profile. For individual importers (personas físicas), both the 13-character RFC and CURP (Clave Única de Registro de Población) are required.

Vehicle Description: Make (marca), model (modelo), model year (año modelo), version or trim level (versión), vehicle identification number (número de identificación vehicular — NIV, equivalent to VIN), engine displacement or motor type, and category (automóvil, camioneta, motocicleta, or other category under the ISAN rate schedule). For imported vehicles, the customs classification (fracción arancelaria) under the Tarifa de la Ley de los Impuestos Generales de Importación y de Exportación (TIGIE) must also be specified.

Tax Base and Sale Price: The price of transfer or importation value forming the ISAN tax base under Article 2 of the Ley Federal del ISAN — excluding IVA but including accessories, optional equipment, and freight. For importers, the customs value (valor en aduana) established under the Ley Aduanera and the Agreement on Customs Valuation (Acuerdo sobre Valoración en Aduana de la OMC, implemented via the Ley Aduanera) forms the starting point, plus applicable import duties (derechos arancelarios).

Applicable ISAN Rate and Calculated Tax: The applicable rate from the progressive ISAN tariff schedule in Article 3 of the Ley Federal del ISAN, and the calculated ISAN amount. Rates range from 0% for the lowest-value vehicles (below the minimum threshold updated annually) through progressive brackets to rates applicable to luxury automobiles (automóviles de lujo). Electric vehicles meeting the technical specifications published in the SAT's annual Resolución Miscelánea Fiscal are subject to reduced rates or zero rate.

Payment Reference: The línea de captura generated by the SAT e-ISAN system or the payment portal, identifying the specific tax period (ejercicio and período de pago), the SAT office of competent jurisdiction, and the payment amount. The línea de captura must be used within its validity window (typically 3 business days) to make the payment at an authorized banking institution (banco autorizado) or through the SAT's electronic payment channel (pago en línea). The acuse de recibo and payment confirmation are essential records for the purchaser's vehicle registration (emplacamiento) with the Secretaría de Movilidad or equivalent state transport authority.

CFDI Integration: Under the mandatory electronic invoicing regime administered by the SAT, manufacturers and distributors must issue a CFDI (Comprobante Fiscal Digital por Internet) for every new vehicle sale. The CFDI must correctly classify the ISAN component — the ISAN amount appears as a separate line from the vehicle price and IVA in the CFDI XML structure, using the complemento de impuestos locales when state-level charges apply. Errors in CFDI issuance generate SAT audit flags and may trigger requiremientos de información (information requests) under CFF Article 22 even after ISAN has been paid.

Forms-legal.com provides this ISAN Declaration Mexico template as a reference instrument for manufacturers, distributors, and importers. Given the technical complexity of ISAN rate schedules, the interaction between ISAN and IVA for accounting purposes, and the coordination mechanism under the Ley de Coordinación Fiscal, declarations should be prepared by a Contador Público Certificado (CPC) familiar with the automotive sector's fiscal obligations and the SAT's current technical specifications for electronic ISAN filing. Errors in the tax base or rate application that result in underpayment are subject to updating factors (INPC actualization) and surcharges (recargos) under CFF Articles 17-A and 21, plus applicable infraction penalties under CFF Article 76.

Forms-legal.com provides this ISAN Declaration Mexico template as a practical reference for manufacturers, distributors, and importers subject to the Ley Federal del Impuesto sobre Automoviles Nuevos — always confirm current SAT ISAN rates and filing deadlines before submission.
