SAT publication of article 1 of the VAT law.
These references are not an approval of a tax rate. The calculator applies a percentage you enter manually. Selecting Mexico changes the currency, not the applicable tax rules.

What still needs validation
Review the current consolidated law, zero-rating, exemptions, border incentives and eligibility dates. Article 1 alone does not establish treatment of every transaction.
Before a rate can become a preset
Each executable rule needs a specific legal citation, jurisdiction, transaction category, tax base, effective period, exceptions and rounding policy. It also needs independent expected-result tests and recorded human approval. A retrieval date is not an effective date or a tax-professional sign-off.
Calculation method
For a single proportional percentage, add tax using net × rate ÷ 100. To extract included tax, divide the total by (1 + rate ÷ 100). This manual method does not determine whether that percentage legally applies.
