Mexico IVA Guide 2026

Mexico IVA at a glance

Do I need to comply? — 60-second check

Three numbers tell you whether you need to register for Mexico IVA. MXN zero is the effective domestic floor for IVA registration — Mexico has no general turnover threshold; all commercial activity is in scope. MXN 3.5 million / MXN 35 million is the RESICO simplified-regime threshold (individuals / corporates) that determines which compliance path applies for small taxpayers. And 16% is the standard rate that applies to most goods and services nationally (8% in the Northern Border Region for qualifying activities).

Four questions, in order. By the end of them, you will know which compliance path applies:

• Mexican-resident business? All taxable activity is in scope from supply one. The structural choice is between standard IVA taxpayer status and the RESICO simplified regime (for individuals up to MXN 3.5M, corporates up to MXN 35M). The Local Mexican Business track covers the full picture.
• Non-resident vendor supplying digital services to Mexican consumers? Foreign SaaS / Digital Services Seller track. The LIVA Article 18-D foreign digital services regime (effective 1 June 2020) requires non-resident vendors to register, charge 16% IVA on B2C supplies, and submit monthly returns. Among the more mature cross-border digital services frameworks in Latin America.
• Non-resident vendor shipping physical goods to Mexican consumers — Mercado Libre Mexico, Amazon Mexico, Linio, your own store? Foreign E-commerce Seller track. Import IVA at 16% applies at customs alongside Customs Duty (IGI/IGE) and IEPS for specific categories.
• Non-resident vendor importing goods into Mexico for distribution, manufacturing (IMMEX/maquiladora), or onward sale? Foreign Importer track. Import IVA at 16% applies at customs on customs value + Customs Duty + applicable IEPS. Recoverability through input IVA credit for IVA-registered Mexican entities. IMMEX and other preferential frameworks provide structural advantages for export-oriented operations.

Two contextual points worth surfacing up front. First: Mexico’s 16% IVA rate is the standard across most of the country; the 8% Northern Border Region rate operates in border-adjacent municipalities for qualifying activities under specific eligibility criteria. The border-zone treatment requires careful documentation and operational discipline. Second: Mexico’s CFDI 4.0 mandatory e-invoicing infrastructure is one of the most mature and stringent globally — all invoices must be electronically generated, signed with SAT-issued certificates, and validated through Authorised Certification Providers (PACs) before issuance. Foreign-backed Mexican subsidiaries must plan CFDI integration as a day-one operational requirement.

Foreign SaaS / Digital Services Seller into Mexico

Sell SaaS or digital services into Mexico from outside? You’re operating under LIVA Article 18-D — the foreign digital services regime introduced effective 1 June 2020. The 16% IVA rate applies to B2C digital services to Mexican consumers; non-resident vendors register through SAT’s dedicated foreign supplier portal, charge 16% IVA on consumer-facing invoices, and submit monthly returns. The regime is among the more mature cross-border digital services frameworks in Latin America, and the structural choice between direct registration (Article 18-D) and operating through Mexican subsidiary depends on revenue scale and B2B vs B2C mix.

Are your Mexican sales actually in Mexico’s tax base?

Place of supply for cross-border digital services follows the recipient’s location. LIVA Article 18-B sets out the indicators expected: customer billing address in Mexico, payment instrument issued by a Mexican institution, IP address resolving to Mexico, telephone country code, and other commercially relevant location data.

Take Cascadia Outerwear Inc., a Canadian outerwear brand with USD 15 million of global revenue. Cascadia operates a B2C customisation SaaS platform alongside its physical-goods business — a subscription-based custom-design service sold to outdoor-activity enthusiasts globally. Cascadia’s Mexican B2C subscription revenue reached MXN 28 million in 2025 (approximately USD 1.4M). Cascadia registered through SAT’s foreign supplier portal in late 2024, applies 16% IVA to Mexican B2C subscriptions, and submits monthly returns. The physical outerwear business operates through Mercado Libre Mexico and Cascadia’s own e-commerce site — sits in the e-commerce track.

When the SAT clock starts running

Three structural triggers.

The Article 18-D trigger applies on every cross-border digital service supply to a Mexican non-RFC-registered consumer. Registration is required for non-resident vendors regardless of revenue threshold — Article 18-D operates on a category-based rather than threshold-based trigger.

The B2B framework operates differently. Mexican RFC-registered business customers receiving imported services self-assess IVA under the imported services framework (Article 24 LIVA) — the non-resident vendor does not register for these B2B supplies.

The permanent-establishment trigger applies when an overseas vendor creates a Mexican presence (representative office, subsidiary, dependent agent). The Mexican presence enters the full standard IVA framework with RFC registration, CFDI infrastructure, and monthly compliance.

Getting registered with SAT

Registration runs through SAT’s dedicated foreign supplier portal. Four operational steps:

• Apply for the Foreign Resident Digital Services RFC through SAT. Required information includes business name and home jurisdiction details, authorised representative information, business activity description, and projected Mexican revenue.
• Receive the foreign vendor RFC identifier assigned by SAT. The RFC appears on every invoice issued to Mexican customers.
• Designate a Mexican tax representative if appropriate. Article 18-D doesn’t strictly require a Mexican representative but practical compliance is materially easier with one engaged.
• Configure billing platform for Mexican 16% IVA on B2C digital services, with the foreign vendor RFC displayed on invoices, and B2B-imported-services treatment handled through customer-side self-assessment.

What you charge, and on what

Mexican IVA at 16% applies to B2C digital services to Mexican consumers under Article 18-D. The 8% Northern Border Region rate does not generally apply to cross-border digital services.

For B2B supplies to RFC-registered Mexican business customers, the Mexican customer self-assesses IVA under the imported services framework. Confirm the customer’s RFC status before invoicing on a no-IVA basis.

Consider BrightLearn Inc. selling USD 79/month subscriptions. A Mexico City consumer subscribes. BrightLearn charges USD 79 + 16% IVA = USD 91.64, collects the MXN equivalent of USD 12.64 in IVA, and submits this through the monthly Article 18-D return on SAT’s foreign supplier portal.

What a Mexico cross-border invoice must say

Under Article 18-D, the foreign vendor’s invoice must include:

• Supplier business name and foreign vendor RFC.
• Customer identification (name or email for B2C).
• Invoice date and supply date.
• Description of services supplied.
• Total amount payable, with IVA amount (16%) separately stated.
• For invoices in foreign currency: MXN equivalent of the IVA amount using a SAT-recognised exchange rate.

CFDI 4.0 — Mexico’s mandatory domestic e-invoicing format — generally does not apply to foreign vendors under Article 18-D, who operate under the simplified foreign-supplier invoice format.

Submitting and paying SAT

Article 18-D registrants submit monthly returns through SAT’s foreign supplier portal by the 17th day of the following month.

Payment is made through SAT’s payment infrastructure with international wire transfer to designated bank accounts, or via Mexican banking partnerships if established.

What this actually costs

Approximate operating ranges for an Article 18-D foreign vendor:

• Mexican tax representative (where engaged): USD 6,000–18,000 per year.
• Monthly Article 18-D return preparation: USD 800–2,500 per submission — typically bundled into representative retainer.
• Initial Article 18-D registration through SAT: minor cost; mostly internal effort plus representative onboarding.
• Initial billing-platform configuration for Mexico 16% IVA and foreign vendor RFC handling: USD 4,000–12,000.
• Annual reasonableness review by a Mexican Contador Público Certificado: USD 2,500–8,000 per year.

What we see foreign SaaS sellers get wrong

Three patterns recur. They cost overseas vendors money and exposure in roughly equal measure.

The first: assuming the 8% Northern Border Region rate applies to cross-border digital services to consumers in border-zone municipalities. It generally does not — the reduced rate applies to qualifying domestic activities under specific eligibility, not to Article 18-D cross-border supplies.

The second: misjudging the B2B imported-services treatment. The mechanism applies only where the Mexican customer is RFC-registered. Invoicing a Mexican customer that turns out not to be RFC-registered (typical for small businesses below RESICO thresholds) is a direct compliance breach. Verify RFC status before invoicing — TaxDo’s Global Tax Identity engine validates Mexican RFCs across the SAT registry in real time.

The third: under-investing in indicator capture for customer location. SAT’s audit attention on Article 18-D compliance has matured since the 2020 introduction; the documentation requirement for indicator capture is treated as a substantive compliance line.

If you get this wrong

Sanction framework under CFF and LIVA:

• Late filing of monthly Article 18-D return: MXN 1,400–17,500 per return + updating of tax base.
• Late payment: actualización at INPC + recargos at ~1.47%/month.
• Under-reporting: 55–75% of underpaid IVA (up to 100% for aggressive).
• Defraudación fiscal: criminal prosecution under CFF with imprisonment 3 months to 13 years.

If you’ve been selling without registering

Engage a Mexican tax representative. Voluntary regularisation (regularización) under standard SAT practice unlocks sanction mitigation. Article 18-D enforcement has been progressive since 2020; SAT’s response to clean pre-detection voluntary regularisation is typically constructive.

Foreign E-commerce Seller into Mexico

Shipping physical goods to Mexican consumers? Mercado Libre Mexico, Amazon Mexico, Linio, your own Shopify store, or marketplace-routed models — the import IVA mechanic at customs applies 16% on customs value + Customs Duty (IGI) + applicable IEPS for specific categories. Mexico’s de minimis (USD 117 — increased from USD 50 under USMCA), combined with the cross-border e-commerce expansion since USMCA implementation, has driven significant growth in direct-to-consumer cross-border flows.

Does this apply to your store?

If physical goods you sell arrive at a Mexican address, you’re inside the import-IVA framework:

• Direct cross-border shipping: import IVA at 16% on customs value + Customs Duty (IGI) + applicable IEPS at customs. Mexico’s de minimis is USD 117 CIF per consignment (under USMCA simplified entry rules); below this, most personal-use consignments clear with simplified treatment.
• Mexican fulfilment via Mexican distributor or your own Mexican subsidiary: imported under the Mexican entity’s name; full IVA and customs duty paid at customs; domestic IVA on each onward sale with CFDI 4.0 e-invoicing.
• Marketplace-routed sales via Mercado Libre Mexico, Amazon Mexico, Linio, Shopee Mexico: each marketplace has specific operational treatments. Mercado Libre in particular has integrated tax operational infrastructure for foreign sellers.

Three triggers, three deadlines

Import IVA attaches at every consignment. The registration question is structural: Mexican subsidiary (registers automatically with RFC) vs Mexican distributor (handles importer of record).

Getting set up with SAT (for Mexican subsidiaries)

Mexican subsidiary route: incorporation under Ley General de Sociedades Mercantiles → RFC registration with SAT → Customs Account (Padrón de Importadores) → CFDI 4.0 e-invoicing infrastructure → bank account configurations. Full sequence typically 6–10 weeks. Foreign-invested entities require additional Foreign Investment Registry registration.

Charging IVA on goods, shipping, and returns

Mexican subsidiary as RFC-registered: 16% IVA on most taxable goods (8% in Northern Border Region for qualifying activities). Zero-rated for exports and qualifying food/medicine categories. Exempt categories per Article 9 LIVA.

On import: 16% IVA on customs value + IGI + applicable IEPS. Mexico’s customs duty varies by HS code with rates from zero to high for specific categories. IEPS (Special Tax on Production and Services) applies to alcohol, tobacco, automotive fuel, sugary beverages, and other specified categories — rates vary materially.

Returns operate as credit-note adjustments through the CFDI 4.0 system. Issue a CFDI Egreso (credit note) referencing the original invoice’s UUID.

Take Maple Goods Co. operating through a Mexican subsidiary. Maple imports household goods consignment, paying customs duty (assume 15%) and IVA (16%) at customs. The subsidiary sells an MXN 800 item to a Guadalajara consumer. The invoice (CFDI 4.0) is MXN 800 + 16% IVA = MXN 928. Maple’s subsidiary collects IVA, submits monthly through Buzón Tributario, claims input IVA credit.

Invoice rules for e-commerce

CFDI 4.0 mandatory for all Mexican RFC-registered entities. Each invoice must be electronically signed with SAT-issued certificates, validated through an Authorised Certification Provider (PAC), and receive a UUID (Universally Unique Identifier) before being shared with the buyer.

For marketplace-routed sales, marketplaces handle their own CFDI 4.0 infrastructure for platform fees; sellers operating through marketplaces require their own CFDI capability for sales they originate.

Submitting — and the marketplace question

Mexican subsidiary submits monthly IVA returns through Buzón Tributario by the 17th of the following month.

The marketplace question for Mexican e-commerce has evolved with SAT guidance on platform operator obligations. Mercado Libre Mexico has the most integrated foreign-seller tax operational infrastructure; Amazon Mexico, Linio, and Shopee Mexico operate differently. Confirm in writing per marketplace.

The compliance cost stack

Total run-rate for mid-volume foreign e-commerce through Mexican subsidiary typically lands in USD 25,000–100,000 per year. Subsidiary establishment is a separate one-time cost USD 8,000–30,000.

What we see e-commerce sellers get wrong

The first: misjudging the USD 117 de minimis. Per consignment, not per item. Consignments above the de minimis attract full customs treatment.

The second: under-investing in CFDI 4.0 infrastructure readiness. The Mexican e-invoicing requirement is among the most stringent globally; integration delays create immediate operational disruption.

The third: misjudging Northern Border Region treatment. The 8% reduced rate applies only to qualifying domestic activities in eligible border-zone municipalities — not to cross-border imports or to activities outside the eligibility scope.

The sanction exposure

Same framework: MXN 1,400–17,500 per late return + INPC updating + ~1.47%/month surcharges, 55–75% under-reporting, criminal exposure for fraud. Plus Customs Law penalties for misdeclaration.

If you’ve been selling without proper structure

Engage a Mexican tax advisor with cross-border e-commerce experience. Voluntary regularisation prior to SAT audit unlocks sanction mitigation.

Foreign Importer / Physical Goods Seller into Mexico

Import IVA at 16% on customs value + IGI customs duty + applicable IEPS, customs duty per HS code (Mexico’s TIGIE tariff with USMCA preferential treatment for US/Canada origins), recoverability through input IVA credit for IVA-registered Mexican entities, and the IMMEX/maquiladora and IMMEX-affiliated frameworks providing structural preferential treatment for export-oriented manufacturing operations. The structural choices for foreign importers: full Mexican subsidiary, DDP sale to a Mexican distributor, or operation through an IMMEX-registered maquiladora arrangement. The IMMEX/maquiladora framework is particularly significant for North American supply chains given Mexico’s role as the primary manufacturing hub for the USMCA region.

Whether you’re the importer of record

Bring goods into Mexico and Mexican Customs (Aduana, under SAT) assesses IGI customs duty (HS-code dependent, with USMCA preference for US/Canadian-origin goods), IVA at 16%, applicable IEPS, and any sector-specific levies. Combined liability is payable at clearance — unless an IMMEX/maquiladora or bonded warehouse arrangement defers it.

Trigger event → statutory deadline

Import IVA attaches at every consignment. Registration question is structural: Mexican subsidiary or distributor.

The registration walk-through (customs and IVA together)

Three importer-specific registrations on top of standard RFC registration:

• Padrón de Importadores (Importer Registry) with SAT through the Aduana portal — required for all commercial importers.
• Padrón Sectorial de Importadores for specific sectoral categories (chemicals, textiles, footwear, alcohol/tobacco, motor vehicles) — additional sectoral registration.
• IMMEX/maquiladora authorisation for qualifying export-oriented manufacturing operations — provides material IVA, customs duty, and operational advantages.

How import IVA is calculated

Standard 16% IVA on customs value + IGI customs duty + applicable IEPS. For consumer and industrial goods at moderate duty rates, the cumulative landed cost is manageable but materially affected by HS code and origin treatment under USMCA.

Run the numbers on a USD 100,000 customs-value consignment at 10% IGI customs duty (typical for many consumer goods; lower or zero for USMCA-origin goods). IGI = USD 10,000. IVA base = customs value + IGI = USD 110,000. IVA at 16% = USD 17,600. Total at clearance: USD 27,600. For USMCA-origin goods qualifying for preferential treatment, IGI drops to zero, materially reducing landed cost: customs value USD 100K → zero IGI → USD 16K IVA → total USD 16K at clearance. The IVA is recoverable as input credit for IVA-registered Mexican entities.

Invoicing for re-sold imports

CFDI 4.0 format applies for onward sales. Reference the Pedimento (import declaration) number on the CFDI for goods imported and re-sold; this links customs to IVA records and is a standard SAT audit reconciliation point.

Submitting and where importers extract real value

Mexican subsidiary submits monthly IVA returns through Buzón Tributario. The input IVA recovery is where importers extract most compliance value at the 16% rate. Reconciliation between import IVA paid (Aduana Pedimento records) and input credit claimed (monthly IVA return) is the standard SAT audit starting point.

The real cost of compliance for importers

Itemised cost matrix for a mid-sized foreign importer through Mexican subsidiary (MXN 50M–MXN 1B annual Mexican turnover):

What we see importers get wrong

Four lines we audit:

• HS classification correct and defensible — Aduana scrutiny is active.
• USMCA origin documentation in place where preferential treatment is claimed — Certificate of Origin requirements under USMCA.
• Input IVA reconciliation discipline — Pedimento records vs monthly IVA return.
• IMMEX/maquiladora documentation chain where preferential treatment is claimed.

Customs and IVA sanctions together

SAT sanction framework plus Customs Law (Ley Aduanera) penalties for misdeclaration, undervaluation, or violation of import controls — goods seizure, fines exceeding the customs duty involved, importer blacklisting.

If you’ve been importing without proper structure

Engage both a Mexican Agente Aduanal AND a Mexican tax advisor before voluntary regularisation. Reconciliation across customs and IVA chains must be clean.

Local Mexican Business

If your business is established in Mexico, IVA applies from supply one — Mexico has no general turnover floor for IVA registration. The structural choice is between standard IVA taxpayer status (Régimen General) and the RESICO simplified regime for small taxpayers (Régimen Simplificado de Confianza). The bigger 2026 questions for Mexican-resident businesses are about CFDI 4.0 operational discipline (mature and stringent, with continued SAT enhancements), the Buzón Tributario digital communication infrastructure, and the operational compliance with the monthly Declaración de IVA rhythm.

When IVA registration kicks in

Mexico has NO general turnover floor for IVA registration — all commercial activity is in scope from supply one. The structural choice is between standard IVA taxpayer status (Régimen General de Ley) and the RESICO simplified regime for small taxpayers (individuals up to MXN 3.5M annual; corporates up to MXN 35M annual).

Acting in time and what backdating means

Within 30 days of commencing taxable activity. SAT’s enforcement infrastructure (CFDI 4.0 real-time validation, Buzón Tributario digital communication) makes operational gaps quickly visible.

Registering as a resident Mexican business

Through SAT’s e.firma (electronic signature) and RFC registration infrastructure. Documents required: business incorporation documents (Acta Constitutiva), proof of business address (Comprobante de Domicilio), representative identification, e.firma electronic signature certificate. Most registrations complete within 2–4 weeks of full application.

What you charge — and the zero-rated vs exempt distinction

Standard rate 16% (8% in qualifying Northern Border Region activities). Zero-rated 0% on exports and qualifying food/medicine — input IVA credit recoverable. Exempt supplies (residential property, most financial services, education, certain medical services) — outside IVA system, input IVA on related costs generally not recoverable.

Invoicing rules and the CFDI 4.0 infrastructure

Mandatory CFDI 4.0 for all RFC-registered Mexican entities. Each invoice must be generated electronically, signed with SAT-issued e.firma certificate, validated through an Authorised Certification Provider (PAC), and receive a UUID before being shared with the buyer. Among the most mature and stringent mandatory e-invoicing regimes globally.

Filing the periodic return rhythm for local businesses

Monthly Declaración de IVA through Buzón Tributario by the 17th of the following month. Annual income tax reconciliation (ISR Declaración Anual) separate.

The internal cost of being IVA-compliant

Small business under RESICO: simplified compliance. Mid-sized business (MXN 100M+ revenue) on Régimen General: MXN 500,000–2,500,000 per year on external Contador Público Certificado support.

The traps for local Mexican businesses

Where do most local Mexican finance teams trip up first in 2026?

Mis-applying the CFDI 4.0 cancellation framework. The 2022 reforms tightened invoice cancellation procedures — improperly cancelled CFDIs trigger SAT enforcement attention. Discipline around the cancellation workflow matters.

What’s the second?

Mis-managing the Northern Border Region 8% rate. Eligibility criteria are specific (geographic, activity-based); operating under the reduced rate without meeting eligibility creates retroactive exposure.

And the third?

Mis-applying the RESICO simplified regime vs Régimen General choice. The regime choice has material tax economics implications; transitioning from RESICO once revenue crosses thresholds requires careful planning.

Sanction exposure for residents

Same framework: MXN 1,400–17,500 per late return, INPC updating, ~1.47%/month surcharges, 55–75% under-reporting, criminal exposure for fraud.

Catching up after a misclassification

Voluntary regularisation prior to SAT audit unlocks sanction mitigation under standard SAT practice.

Cross-track essentials

Invoicing requirements

CFDI 4.0 (Comprobante Fiscal Digital por Internet version 4.0) — mandatory electronic invoicing format. Each invoice generated, signed with e.firma certificate, validated through a PAC, and assigned a UUID before issuance. Mandatory elements include supplier RFC, customer RFC (or generic RFC for B2C), invoice details, applicable IVA rate and amount, and UUID.

CFDI 4.0 and Buzón Tributario

CFDI 4.0 is one of the most mature mandatory e-invoicing regimes globally. Buzón Tributario is SAT’s mandatory digital communication mailbox for all RFC-registered taxpayers; SAT notifications, audit communications, and information requests flow through Buzón Tributario.

Audit and record-keeping

Records retained 5 years from date of relevant tax filing under CFF. Electronic records standard under CFDI infrastructure. SAT audits are routine and increasingly data-driven through CFDI integration.

Sanctions summary

Voluntary regularisation under standard SAT practice unlocks sanction mitigation.

Frequently asked questions

What is the Mexico IVA rate in 2026?

For all sellers

16% standard rate nationally. 8% reduced rate in qualifying Northern Border Region activities. Zero-rated 0% on exports and qualifying food/medicine. Exempt categories include residential property, most financial services, education, certain medical services.

Do foreign companies need to register for Mexico IVA?

For overseas businesses

Yes — non-resident vendors supplying digital services to Mexican consumers must register under LIVA Article 18-D (effective 1 June 2020). 16% IVA on B2C; B2B uses imported-services self-assessment by RFC-registered Mexican buyers. Monthly returns through SAT’s foreign supplier portal.

What is the Mexico IVA registration threshold for resident businesses?

For local Mexican businesses

Mexico has NO general turnover threshold — all commercial activity is in scope. The RESICO simplified regime applies for small taxpayers (individuals up to MXN 3.5M, corporates up to MXN 35M).

How often do I submit Mexico IVA returns?

For all registered taxpayers

Monthly Declaración de IVA through Buzón Tributario by the 17th of the following month. Annual ISR (income tax) reconciliation separate. Foreign Article 18-D registrants submit monthly through SAT’s foreign supplier portal.

What is the late-payment surcharge in Mexico?

For all registered taxpayers

INPC actualización (consumer price index updating) + recargos at approximately 1.47% per month (rates updated quarterly via Diario Oficial). Late filing penalties MXN 1,400–17,500 per return.

What is Article 18-D of LIVA?

For overseas digital service providers

Mexico’s foreign digital services regime effective 1 June 2020. Non-resident vendors register, charge 16% IVA on B2C supplies to Mexican consumers, submit monthly returns through SAT’s foreign supplier portal. Among the more mature cross-border digital services frameworks in Latin America.

What is the Northern Border Region 8% rate?

For businesses operating in border-zone municipalities

Reduced IVA rate of 8% in qualifying activities in municipalities adjacent to the US border. Eligibility criteria are specific (geographic, activity-based, operational). Does not generally apply to cross-border imports or to activities outside the eligibility scope.

What is CFDI 4.0?

For all Mexican RFC-registered businesses

Comprobante Fiscal Digital por Internet version 4.0 — Mexico’s mandatory electronic invoicing format. Each invoice must be electronically signed with SAT-issued e.firma certificate, validated through an Authorised Certification Provider (PAC), and receive a UUID before being shared with the buyer.

How does the B2B imported-services mechanism work?

For overseas suppliers and Mexican business customers

Mexican RFC-registered business customers receiving imported services from non-resident vendors self-assess IVA under Article 24 LIVA. The non-resident vendor does not charge IVA. Confirm RFC status before invoicing on a no-IVA basis.

How is import IVA calculated at Mexican customs?

For foreign importers

16% IVA on customs value + IGI customs duty + applicable IEPS. For USMCA-origin goods qualifying for preferential treatment, IGI drops to zero — materially reducing landed cost. IVA recoverable as input credit for RFC-registered Mexican entities.

What is IMMEX/maquiladora?

For foreign manufacturers and importers

Industria Manufacturera, Maquiladora y de Servicios de Exportación — Mexican framework providing structural preferential treatment (IVA deferral, customs duty advantages) for qualifying export-oriented manufacturing operations. Significant for North American supply chains under USMCA.

How do I correct an error in a Mexican IVA return?

For all registered taxpayers

Voluntary regularisation (regularización voluntaria) under standard SAT practice unlocks sanction mitigation. Submit the corrected return through Buzón Tributario with supporting documentation. Engage a Mexican Contador Público Certificado before initiating.
