Zero Mexican VAT on the customer line can mean three different things
A zero-rated sale, an exempt sale, and an out-of-scope event do not create the same input-IVA result. Mapping all three to one tax code can corrupt CFDI data and the recoverable-VAT calculation.
A product team launches a Mexican catalog from global ERP labels: STANDARD, ZERO, and EXEMPT. That is not enough. Mexico's classification follows the exact legal transaction, product characteristics, preparation, location, and statutory exception. A name imported from another country cannot decide Mexican IVA.

Use a tax-effect matrix
| Mexico treatment | Output IVA | Input IVA consequence |
|---|---|---|
| 16% taxable | Charge at general rate | Potential credit if requirements are met |
| 0% taxable | Calculated at zero | Potential credit remains available |
| Exempt | No output tax under an exemption | Related input IVA may be restricted |
| Out of scope | No applicable taxable event | Does not independently support credit |
Article 2-A of the IVA Law says zero-rated activities have the same legal effects as activities on which tax is payable. That sentence is why “zero-rated” must not be translated into “exempt” in a Mexican tax engine.
Product analysis starts below the category name
Mexico's published Article 2-A applies 0% to specified transactions, including qualifying patent medicines and human or animal food products, subject to exclusions. The analysis belongs at SKU and transaction level.
| Master-data question | Evidence |
|---|---|
| What is the item? | Technical sheet, ingredients, packaging and intended use |
| Was it prepared? | Kitchen or production process and point of sale |
| How is it delivered? | Packaged, dine-in, takeaway or home delivery |
| Is an exclusion triggered? | Exact Article 2-A language |
| Is this a service or a good? | Contract and commercial substance |
| Where is the transaction located? | Mexican territorial rules |
Prepared food can carry 16% even when taken away
Article 2-A applies the general rate to food prepared for consumption at the selling establishment, including takeaway and home-delivery formats. A zero-rated ingredient does not guarantee a zero-rated prepared product.
Exemption is a separate statutory path
Article 9 of the IVA Law exempts specified transfers, including land, qualifying residential construction, and certain books, newspapers, and magazines under the stated facts. Services and leases have their own exemption provisions. Similarity is not enough to extend an exemption.
Out of scope comes before the rate
Ask whether a Mexican sale, service, lease, or import exists under the IVA Law before assigning any rate. An event outside that charging scope is not merely an exempt domestic sale. The distinction matters to CFDI coding and to the denominator used for shared input IVA.
Translate legal treatment into CFDI without collapsing it
SAT's CFDI/Annex 20 information distinguishes whether a line is subject to tax and how it is treated. A mixed invoice should preserve each concept's result; grouping different products into “assorted goods—zero tax” hides the evidence needed for validation.
| System layer | Required alignment |
|---|---|
| Product master | SKU, description, technical facts and legal conclusion |
| POS/e-commerce | Customer price and tax treatment |
| CFDI | Object/tax data and line-level separation |
| General ledger | Output and input IVA accounts |
| IVA return | Taxable, zero-rated, exempt and other activity totals |
| Input allocation | Direct attribution and shared-cost ratio |
Worked launch: health-food catalog
A retailer assigns 0% to fresh produce, a ready-to-eat bowl, flavored juice, and dietary capsules because all appear under HEALTH. Fresh produce may fit a zero-rate provision; the prepared meal and beverage require explicit exclusion analysis; supplements cannot borrow the treatment of ordinary food. The fix begins with product facts, then updates systems and measures historical exposure.
- Freeze new SKU mapping until classification is approved.
- Collect technical files and actual preparation/delivery workflows.
- Document the article, paragraph, exclusion, and effective date.
- Update POS, website, ERP, and CFDI rules together.
- Quantify prior output IVA and input-credit effects by filing period.
- Evaluate invoice correction and amended returns without erasing the original audit trail.
Why zero rating can create a refund position
A zero-rated business charges no output IVA but may pay IVA on rent, professional services, equipment, and other inputs. When Article 5 requirements and attribution are met, those amounts can remain creditable and produce a balance in favor. Exempt activity does not produce the same answer.
Quarterly product-tax review
| Test | Exception |
|---|---|
| All non-16% SKUs have legal support | Tax code assigned from vendor description only |
| Prepared and packaged variants are separate | One code shared across different delivery forms |
| CFDI matches commerce systems | Correct price but wrong tax object |
| New products are approved before sale | Tax reviewed after first return |
| Input IVA is attributed | All purchases credited despite exempt activity |
| Effective dates are retained | Current rule overwrote historical mapping |
Frequently asked questions
Are zero-rated and exempt sales identical for Mexican IVA?
No. Zero-rated activities are taxable activities with legal effects that can preserve input credit. Exempt activities can restrict the input IVA connected to them.
Is every food product zero-rated in Mexico?
No. Article 2-A has exclusions, including rules for prepared food, beverages, and other categories. Review the exact item and selling format.
Can a global ERP ‘exempt’ code represent Mexico's 0% rate?
It should not if it collapses the legal or reporting effect. Configure a Mexican mapping that preserves zero-rated, exempt, and out-of-scope outcomes separately.
Does no output IVA mean no IVA return data?
No. Zero-rated, exempt, and other activity values can affect reporting, credits, allocation, and refund support even when the customer sees no IVA amount.
