# Tax Groups

Tax Groups, as the name suggests, group together a set of related Tax Codes and present a single rate which is the sum of the constituent Tax Code Rates. Tax Groups are used when you need to apply multiple Tax Rates to your Sales Line Items.

**Note:** You can assign a default Tax Group to a Customer so that when an associated Sales Document is created (such as a Sales Invoice), it will automatically be assigned the default Tax Group.

The Tax Group document is shown below:

**Note:** The Group Tax Rate is the sum of the selected Tax Code rates. As you select the appropriate Tax Codes from those listed you will notice the Group Rate change accordingly.

## 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://helpwith.salesorder.com/accounting/tax/tax-groups.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.
