Professional Services Receipt Mexico (Recibo de Honorarios)

A Professional Services Receipt Mexico (Recibo de Honorarios) is a fiscal and civil document issued by a self-employed professional (profesionista independiente or persona física con actividad profesional) to the client (persona física or persona moral) paying for professional services, governed primarily by the Ley del Impuesto sobre la Renta (LISR) Articles 100 through 113, the Código Fiscal de la Federación (CFF) Article 29, and the SAT's electronic invoicing rules requiring issuance as a Comprobante Fiscal Digital por Internet (CFDI). The recibo de honorarios documents the professional fee (honorario) charged, establishes the ISR (Impuesto sobre la Renta) withholding obligation, and serves as the tax-deductible comprobante for the client.

Under LISR Chapter II of Title IV (Articles 100–113), professionals who render independent personal services (servicios personales independientes) — including médicos (physicians), abogados (lawyers), contadores públicos (accountants), arquitectos (architects), ingenieros (engineers), notarios (notaries public in their professional capacity beyond their notarial function), and any other licensed professional — are taxed on their honorarios income as part of the Régimen de Actividades Empresariales y Profesionales or the Régimen Simplificado de Confianza (RESICO) introduced by the 2022 tax reform. LISR Article 100 defines this income category and establishes the monthly provisional payment (pago provisional mensual) obligations.

The SAT CFDI requirement under CFF Article 29 mandates that all professionals registered with the SAT issue CFDIs for every payment of honorarios received. The CFDI must be issued through a PAC (Proveedor Autorizado de Certificación) and include the professional's RFC, the client's RFC, the service description (descripción del servicio), the amount before IVA (Impuesto al Valor Agregado at 16% unless exempted), and the applicable ISR withholding amount. Failure to issue CFDIs constitutes a CFF infraction subject to sanctions under CFF Article 82.

ISR Withholding (Retención de ISR sobre Honorarios): Under LISR Article 106, when a persona moral (company) pays honorarios to a persona física (professional individual), the company is obligated to withhold 10% ISR on the gross amount of the honorarios and remit this withholding to the SAT on behalf of the professional through the monthly DIOT (Declaración Informativa de Operaciones con Terceros) and the provisional payment declaration. The professional then credits the withheld amounts against their annual ISR liability. When the client is another persona física not engaged in business activities, no withholding obligation exists — the professional must pay their own ISR directly.

IVA Treatment (Impuesto al Valor Agregado): Professional services rendered in Mexico are generally subject to IVA at the rate of 16% under the Ley del Impuesto al Valor Agregado (LIVA) Article 14. However, certain medical services rendered by qualified physicians (médicos titulados) are exempt from IVA under LIVA Article 15 Section XIV. Legal, accounting, engineering, and architectural services are fully subject to 16% IVA. The recibo de honorarios must state the pre-IVA base amount (base), the IVA amount separately, the ISR withholding amount, and the net amount payable (neto a pagar) to the professional.

The Tribunal Federal de Justicia Administrativa (TFJA) has issued jurisprudencia confirming that honorarios income is taxable in the period when payment is actually collected (cobrado), not when the service is rendered — the cash-basis principle (base de efectivo) applies to professionals under both the general Actividades Profesionales regime and RESICO under LISR Articles 100 and 113-E respectively.

A Professional Services Receipt Mexico (Recibo de Honorarios) is required whenever a self-employed professional in Mexico receives payment for independent personal services and must satisfy both the fiscal documentation obligation under CFF Article 29 and the client's right to a deductible comprobante under LISR.

The recibo de honorarios is mandatory when a company (persona moral) pays a professional: the company must obtain the CFDI to deduct the expense under LISR Article 27 Section III, and must withhold 10% ISR under LISR Article 106 from the payment. Without a valid CFDI de honorarios, the company cannot deduct the professional fee payment in its annual ISR return.

Medical professionals — including médicos generales, especialistas, dentistas (odontólogos), and psicólogos — require recibos de honorarios for each consultation, procedure, or treatment rendered. Patients who hold a private health insurance policy (seguro de gastos médicos mayores) need the CFDI de honorarios to submit reimbursement claims to the insurance company (aseguradora). The insurance company will not reimburse without a valid CFDI from the treating physician.

Law firms (despachos de abogados) and individual lawyers (abogados independientes) issue recibos de honorarios for legal consultations, document preparation, litigation representation, and any professional legal service. Corporate clients require CFDIs de honorarios to deduct legal fees under LISR Article 25 and to document the expense in their financial statements under NIF (Normas de Información Financiera) C-9.

Architects, civil engineers, and urban planners (arquitectos, ingenieros civiles, urbanistas) issue recibos de honorarios for project design, supervision, technical review, and consulting services. Construction companies and real estate developers require these CFDIs to deduct professional fees against the cost basis of construction projects under LISR Articles 30 and 32.

Under the RESICO (Régimen Simplificado de Confianza) established by the 2022 reform of LISR Articles 113-E through 113-I, professionals with annual income below $3.5 million MXN may opt into this simplified regime with reduced ISR rates. RESICO professionals still must issue CFDIs for all honorarios received and may have different withholding rules — always verify the professional's regime with their RFC registration before applying withholding rates.

Government agencies and public institutions (dependencias gubernamentales) contracting independent professionals must obtain recibos de honorarios with CFDI under the Ley de Adquisiciones, Arrendamientos y Servicios del Sector Público — such contracts typically require the professional to be registered in the government's supplier registry (padrón de proveedores) and to issue CFDIs meeting SAT's CFDI 4.0 requirements including the professional's full fiscal address.

A valid Professional Services Receipt Mexico (Recibo de Honorarios) under LISR Articles 100–113 and CFF Article 29 must include the following elements:

Professional's Fiscal Data (Datos Fiscales del Profesionista): The professional's full name or corporate name, RFC with homoclave, and registered tax address (domicilio fiscal ante el SAT). The RFC must be active (vigente) in the SAT's RFC registry — clients can verify RFC validity through the SAT's online portal (sat.gob.mx). For professionals in RESICO, the regime must be disclosed on the CFDI.

Client's Fiscal Data (Datos del Cliente): The client's full legal name or corporate name, RFC, and fiscal address. When the client is a persona moral, their RFC must be included for withholding purposes under LISR Article 106. For individual clients without RFC, 'XAXX010101000' (public general) is used on the CFDI.

Service Description (Descripción del Servicio): A specific, accurate description of the professional service rendered — for example, 'Asesoría jurídica en materia de derecho corporativo correspondiente al mes de enero 2026' or 'Consulta médica de especialidad en cardiología del paciente [name], fecha [date]'. The SAT's CFDI validation requires a meaningful service description; generic descriptions such as 'servicios profesionales' may trigger SAT audit flags.

Honorario Base Amount (Subtotal antes de IVA): The professional fee amount before IVA, expressed in Mexican pesos (MXN). This is the base on which IVA at 16% and ISR withholding at 10% are calculated.

IVA (Impuesto al Valor Agregado): The IVA amount at 16% of the base honorario for taxable professional services. Medical services by licensed physicians are exempt under LIVA Article 15 Section XIV — if exempt, the CFDI must state 'exento de IVA'.

ISR Withholding (Retención de ISR): When the client is a persona moral, 10% ISR withholding under LISR Article 106 on the gross honorario amount. The CFDI shows the withholding as a deduction from the total payable. The withheld amount is remitted by the client to the SAT, not paid to the professional.

Net Amount Payable (Total Neto a Pagar): The final amount the client actually pays: Base + IVA − ISR Withholding. This figure must match the bank transfer (SPEI) or cheque amount actually paid.

Payment Date and Method (Fecha y Forma de Pago): The SAT CFDI complement requires the payment method (forma de pago: '03' for SPEI transfer, '04' for tarjeta de crédito, '01' for cash) and the payment date. For deferred payments, the CFDI complement de pago (complemento de pago 2.0) must be issued at the time of actual payment.

Professional Licence Reference (Cédula Profesional): For licensed professionals — abogados, médicos, contadores, arquitectos, ingenieros — including the professional licence number (número de cédula profesional) issued by the Secretaría de Educación Pública (SEP) on the recibo de honorarios reinforces the professional's legal standing to render the service and supports the IVA exemption claim (for medical services) or confirms the professional's regulatory compliance.

Contract Reference (Referencia al Contrato de Honorarios): Where the professional services are rendered under a written honorarios contract (contrato de prestación de servicios profesionales), the receipt should cite the contract date and parties — this links each payment to the underlying contractual obligation and establishes the payment sequence for multi-payment engagements.

Forms-legal.com provides this Professional Services Receipt Mexico template as a reference for understanding honorarios documentation requirements. All formal recibos de honorarios must be issued as CFDIs through a SAT-authorized PAC — a paper-only recibo de honorarios does not satisfy CFF Article 29 for any professional registered with the SAT.
