# IVA

O IVA (Índice de Valor Agregado) também chamado de margem de lucro, é estabelecido pelo fisco de acordo com os aspectos específicos de cada mercadoria.\
BC = (Valor mercadoria + frete + IPI + outras despesas) x margem de lucro.\
A margem de valor agregado será determinada com base nos preços praticados no mercado, obtidos por levantamento, ainda que por amostragem ou através de informações e outros elementos fornecidos por entidades representativas dos setores, adotando-se a média ponderada dos preços coletados. A mercadoria submetida ao regime de substituição tributária em operação interestadual terá a margem de valor agregado estabelecida em Convênio ou Protocolo.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ajuda.consistem.com.br/glossario/iva.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
