The Corp Q3 Final 2026 Final Pack covers the formal close of the third fiscal quarter, which is the transition quarter for Mexican corporate groups: summer tourism is behind, Tianguis Turístico Rosarito closes the cycle, the US parent closes its fiscal year (April-March calendar) and sends its SEC report, and the Mexican corporate group kicks off budget planning for the next fiscal year. The pack delivers the Q3 CFDI 4.0 reconciliation file before 30 September, with quarterly obligations and preparation for the annual close.
The Q3 Final integrates four formal components that the corporate group receives between 25 September and 5 October, ahead of the quarterly SAT return (due the last business day of October). Q3 is particularly sensitive for groups with IMMEX presence because it coincides with the US parent fiscal year close (April-March calendar), which requires the consolidated IMMEX report to be delivered to the parent before 30 September so the parent can include it in its SEC 10-K.
The Q3 file includes the consolidated detail of temporary and definitive exports during the quarter, with pedimento number, Carta Porte 3.0, tariff fraction, and final destination of the piece. For groups with SEC 10-K reporting, the file includes an English-language annex with the translation of the key fields, which simplifies consolidation of the IMMEX report for the parent.
The Q3 report includes the reconciliation of Tianguis Turístico Rosarito (end of September): pieces delivered as corporate staff kit, amount invoiced under unit key E48; pieces delivered as promotional piece for international clients, amount under unit key G03 with General Tourism Law compliance. For groups with tourism operations, the report also includes the reconciliation of summer operations in coastal destinations.
The Q3 Final executive report includes the consolidated detail of operations that require UIF notice during the quarter: gifts, prizes, raffles, and donations that exceed the current UMA thresholds under the LFPC. The report classifies each operation by vulnerable activity, amount, and recipient, which simplifies the client’s compliance submission in the AML portal.
We run the merch line for the 2027 budget planning workshop that Mexican groups typically run between September and November: executive folders in leather tanned in León, USB with digital annexes, and a curated piece for the planning committee members. Coordination with FP&A and the CFO’s office for compliance with the internal budget presentation deadlines to the board.
Q3 is the Mexican fiscal quarter that coincides with the US and Canadian parent’s April-March fiscal year close. For Mexican corporate groups with IMMEX operations and USMCA presence, this means the Q3 Final file serves simultaneously the Mexican quarterly SAT return and the parent’s SEC annual report (10-K) or Canadian Securities Administrators filing (40-F or 20-F as applicable). The file must meet the fiscal requirements of both countries and the multinational’s reporting policies.
Additionally, Q3 is the quarter when Tianguis Turístico runs, Mexico’s most important tourism promotion event in Mexico and Latin America, normally held in Rosarito, Baja California. For groups with tourism, hotel, or entertainment operations, Tianguis concentrates a significant share of the quarter’s commercial spend, which forces the tax function to correctly document each delivery for deduction and for LFPC compliance.
Q3 also kicks off the preventive UIF notices for groups with intensive prize, raffle, and gift operations during Buen Fin and year-end (which run in Q4 but plan in Q3). The Q3 Final executive report identifies the operations that will require notice in Q4, which lets the client’s compliance function prepare the documentation ahead of time.
The Q3 close starts with brief confirmation by 15 September 2026. Corp-Merch.MX processes the quarter’s CFDI reconciliation during the last week of September and delivers the final file between 28 and 30 September. The merch line for the tax team is delivered between 25 and 30 September. The merch line for the 2027 budget planning workshop is delivered 8 days before the scheduled date, normally between 15 and 30 October.
For groups with IMMEX operations, the Q3 Final file includes a specific annex for the US parent: detail of temporary exports with expected return date, detail of definitive exports, total amount of pieces delivered to plant staff, USMCA compliance, and Mexican fiscal compliance. The annex is delivered in English with standard IRS terminology.
Q3 Final invoicing runs as a single consolidated CFDI or as separate CFDIs per component. Each CFDI carries its unit key, its recipient tax regime, and its CFDI use. For IMMEX deliveries, the foreign trade complement is included with 0% IVA rate. For summer temporary staff deliveries in tourism destinations, the CFDI is issued without the complement but with the specific tourism-sector unit key.
The operational brief close is 15 September 2026. That allows the quarter’s CFDI reconciliation to be processed during the last week of September and the final file delivered before 30 September. Briefs arriving after 15 September are processed for deliveries from the second half of October onwards, after the SAT quarterly return and after the USMCA parent’s fiscal year close.
Yes. For clients with a US parent, the Q3 Final file includes an English annex with the key fields for SEC 10-K consolidation: total temporary export amount, total definitive export amount, pieces delivered to plant staff, USMCA compliance, and Mexican fiscal compliance. The translation uses standard IRS terminology.
The Q3 Final executive report identifies prize, raffle, and gift operations that ran during the quarter and require UIF notice under the LFPC. The report classifies each operation by vulnerable activity, UMA amount, and recipient, which simplifies the client’s compliance submission in the AML portal within 30 calendar days following the operation.
