What Is a Excess Withholding Refund Request Mexico (Solicitud de Devolución de Exceso de Retención ISR)?

The Excess Withholding Refund Request Mexico (Solicitud de Devolución de Exceso de Retención del Impuesto sobre la Renta de Sueldos y Salarios) is the formal instrument through which a worker (trabajador) or an employer (patrón) requests recovery of ISR amounts that were withheld from wages in excess of the taxpayer's actual annual ISR liability. The two principal legal bases are Article 22 of the Código Fiscal de la Federación (CFF), which establishes the general right of taxpayers to request refunds of amounts unduly paid or overpaid (cantidades pagadas indebidamente o en exceso) to the federal treasury, and Article 97 of the Ley del Impuesto sobre la Renta (LISR), which governs the employer's obligation to perform the annual ISR adjustment (cálculo anual del ISR) and to refund any resulting overpayment directly to the worker through the payroll.

Excess ISR withholding from wages arises because monthly ISR is withheld on a period-by-period basis using the monthly tariff under LISR Article 96, which applies the progressive rate schedule (tarifa) to the monthly income without perfect visibility into the worker's total annual income. Annual income fluctuations — months with lower-than-average wages, extended unpaid leaves of absence, mid-year hires, or mid-year terminations — often result in monthly withholdings that, when aggregated, exceed the amount computed under the more precise annual tariff of LISR Article 152. The employer's annual adjustment (cálculo anual) under Article 97 LISR reconciles this difference.

Under Article 97 LISR, employers must perform the cálculo anual del ISR for every worker who was employed with the same employer throughout the entire calendar year and who did not have additional income sources outside of wages. The employer applies the annual ISR tariff (Article 152 LISR) to the worker's total annual taxable wage income, computes the correct annual ISR, and compares it against the total ISR withheld monthly. Where the withheld amount exceeds the correct annual liability, the employer must refund the excess (diferencia a favor del trabajador) to the worker through the December payroll or through a special payment no later than 31 March of the following year. The employer then recovers the refunded amount by crediting it against its own ISR monthly withholding deposits with the SAT.

Where a worker had multiple employers during the year, changed employers mid-year, had non-wage income, or opted out of the employer's annual adjustment by submitting a written request under Article 97 LISR, the worker must file their own annual ISR declaration (declaración anual de personas físicas) by 30 April of the following year and claim the refund directly from the SAT using the refund request process under CFF Article 22 through the SAT portal. The SAT processes CFF Article 22 refund requests through the Devoluciones y Compensaciones module on the portal sat.gob.mx, generating a folio number and processing the refund within the 40-business-day period established in CFF Article 22, extendable to 20 additional days for the first refund when the taxpayer has not previously received refunds from the SAT.

The mandatory electronic CFDI de Nómina regime — under which employers must stamp every payroll payment as a CFDI (Comprobante Fiscal Digital por Internet) through a PAC (Proveedor Autorizado de Certificación) authorised by the SAT — transformed the refund claim process by creating a pre-populated electronic income and withholding record for every worker. The SAT's declaración anual prellenada (pre-filled annual declaration) automatically aggregates all CFDI de Nómina data, allowing wage-only workers to review and file their annual declaration in minutes with accurate pre-filled withholding data. This reduces administrative burden for refund claims while also enabling the SAT to cross-check worker-declared amounts against employer-reported CFDI data, creating a closed verification loop for compliance purposes.

When Do You Need a Excess Withholding Refund Request Mexico (Solicitud de Devolución de Exceso de Retención ISR)?

The Excess Withholding Refund Request Mexico is needed in two distinct scenarios based on whether the adjustment is handled by the employer under LISR Article 97 or claimed directly from the SAT under CFF Article 22.

The employer-side refund under Article 97 LISR is needed at year-end when the employer performs the mandatory annual ISR adjustment for workers who were employed with the same employer throughout the calendar year. Most full-year workers with uniform monthly wages will have minimal excess withholding — but workers who took extended unpaid sick leave, received a mid-year salary reduction, had months with irregular bonus payments that inflated specific months' withholdings, or were on maternity or paternity leave with reduced wages are likely to have a diferencia a favor. The employer identifies these workers through the SUA or payroll software's year-end adjustment module and refunds the excess through the payroll.

A direct SAT refund under CFF Article 22 is needed when a worker changed employers during the year — each employer withheld monthly ISR on the worker's income from that employer alone, but the combined annual income from both employers may push the worker into a higher bracket, or alternatively the partial-year income from each employer may have been overtaxed because each employer applied monthly tables as if the income represented a full year. The worker must file their annual declaration, declare combined income from all employers, apply the annual tariff, and claim the net overpayment from the SAT.

The request is also needed when a worker was terminated (finiquito or liquidación) mid-year and received severance compensation that was not taxable (indemnizaciones exentas under LISR Article 93 Fraction XIII) but was nonetheless overtaxed because the paying employer incorrectly included it in the taxable base. In these cases, the former worker must request a SAT refund through the declaración anual.

The request is needed when the subsidio para el empleo was improperly withheld or not fully credited — low-income workers for whom the subsidy fully offset their ISR liability but who nonetheless had nominal ISR withheld due to a payroll calculation error have a right to recovery under both CFF Article 22 and the subsidio framework.

For workers who exercised stock options (opciones sobre acciones) or received restricted stock units (unidades de acciones restringidas) from an employer stock plan during the year, ISR withholding on the exercise or vesting event is complex and frequently results in either over- or under-withholding. Workers in this situation almost always need to file their own annual declaration and either claim a refund or pay additional ISR, depending on the applicable rates and any foreign tax credits (créditos fiscales por impuestos pagados en el extranjero) available under LISR Article 5 where the employer is a foreign multinational.

What to Include in Your Excess Withholding Refund Request Mexico (Solicitud de Devolución de Exceso de Retención ISR)

A valid Excess Withholding Refund Request Mexico must include the following elements whether filed through the employer's Article 97 LISR adjustment mechanism or through the SAT's CFF Article 22 portal process.

Taxpayer Identification: Full name, RFC (13-character individual RFC assigned by the SAT), CURP (18-character Clave Única de Registro de Población), and current address (domicilio fiscal) of the worker requesting the refund. For employer-side adjustments under Article 97 LISR, the employer's Registro Federal de Contribuyentes and IMSS Registro Patronal are also required to link the adjustment to the employer's monthly withholding deposit account at the SAT.

Fiscal Year and Withholding Period: The specific fiscal year (ejercicio fiscal) for which excess withholding occurred, and a breakdown of monthly wages and ISR withheld from each payroll period. The monthly withholding schedule, supported by CFDI de Nómina stamped through the PAC network, is the primary evidence base for demonstrating the amounts withheld. Workers requesting SAT refunds must attach or reference all CFDI de Nómina received during the year — the SAT's electronic systems automatically pre-fill much of the annual declaration with CFDI data, but the worker must verify accuracy.

Annual ISR Calculation: Application of the annual tariff under LISR Article 152 to the total annual taxable wage income (ingreso acumulable del ejercicio), showing the correct annual ISR liability. Deductible amounts and applicable exempt income exclusions (ingresos exentos under LISR Article 93) must be properly separated — overstating exempt income is a common audit trigger. The calculation must show the diferencia a favor (excess withheld over correct annual liability).

Banking Coordinates for Direct Deposit: For SAT refunds under CFF Article 22, the taxpayer must register a CLABE (Clave Bancaria Estandarizada, 18-digit Mexican interbank transfer code) in their SAT portal profile. The SAT processes all refunds via SPEI (Sistema de Pagos Electrónicos Interbancarios) transfer directly to the registered CLABE. The account must be held in the taxpayer's own name — the SAT will not transfer to third-party accounts.

SAT Electronic Filing: Refund requests under CFF Article 22 are filed exclusively through the SAT portal (sat.gob.mx) using the taxpayer's e.firma (Firma Electrónica Avanzada) or contraseña (password). The system generates a folio de devolución (refund tracking number) and an acuse de presentación confirming receipt. Under CFF Article 22, the SAT must resolve the request within 40 business days (extendable to 20 additional for first-time requesters), after which the taxpayer may file an adverse claim (recurso de revocación under CFF Article 116) if the refund is denied or partially adjusted.

Forms-legal.com provides this Excess Withholding Refund Request Mexico template as a practical reference for workers and employers navigating the annual ISR reconciliation process. For SAT portal filings, taxpayers should use the pre-filled declaración anual available through sat.gob.mx, which automatically incorporates CFDI de Nómina data. A Contador Público or authorized tax advisor (asesor fiscal) should review any refund request exceeding $50,000 MXN, as the SAT's risk-scoring system subjects larger refunds to a verification process (revisión de devolución) that may extend the timeline and require additional documentation under CFF Article 22-D.

Forms-legal.com provides this ISR Excess Withholding Refund Mexico template as a practical reference for employers and workers navigating the annual salary adjustment process under LISR Articles 96 and 97 — consult a licensed contador publico to confirm eligibility and calculate the correct refund or charge amount.

Annual Adjustment Timing and Payroll Obligations: The annual ISR salary adjustment (ajuste anual) must be completed by employers in February of the year following the fiscal year under review — specifically, the adjustment calculation must be reflected in the February payroll (nomina de febrero). Employers with more than ten workers are required to perform the annual adjustment for all eligible workers under LISR Article 97; employers with ten or fewer workers may opt out, in which case workers must file their own annual ISR return with SAT to recover excess withholding. The CFDI de Nomina issued for the February payroll adjustment must use the complemento de nomina version 1.2 or higher, reflecting the adjustment amount (diferencia a cargo del patron or diferencia a favor del trabajador) in the corresponding XML fields. Workers who receive a refund from their employer as part of the annual adjustment are not required to file a separate SAT annual return solely on account of that adjustment, provided their only income source is salary from a single employer.
