These references are not an approval of a tax rate. The calculator applies a percentage you enter manually. Selecting Italy changes the currency, not the applicable tax rules.

What still needs validation
This is sector-specific evidence, not a complete national rate schedule. Obtain the current consolidated DPR 633/1972, article 16 and schedules before approving general or reduced presets.
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.
