# list_tax_rates — Tax rates available for invoices

> Reference for the list_tax_rates MCP tool. List the tax rates an organization can apply to invoices.

The `list_tax_rates` tool returns the tax rates an organization can apply to invoice line items. Every request must include `intent` and `organizationId`, and the token must carry the `invoices.read` scope.

> [!NOTE]
>
> Receivables tools require the organization to have invoicing set up in Relay. If it does not, the tool returns an error instead of data.

## Scope

Required OAuth scope: `invoices.read`

## Input

**organizationId** `string` *required*

The organization to query. Must be one of the organizations the token can access.

**cursor** `string`

Opaque pagination cursor from a previous response. Keep the same `pageSize` and filters when following cursors. Never parse, edit, or reuse a cursor across different filter sets.

**pageSize** `integer`

Number of results per page. Must be between 1 and 100. Defaults to 50.

**intent** `string` *required*

What the user asked for and why this call serves it, in 1 to 500 characters. Required on every tool call. See [Common tool arguments](https://mcp.docs.relayfi.com/concepts/transport.md#common-tool-arguments).

**Pagination**

**hasNextPage** `boolean` *required*

**pageSize** `integer` *required*

**nextCursor** `string`

Opaque cursor to fetch the next page. Present only when `hasNextPage` is `true`.

## Example

```json Request theme={null}
{
  "jsonrpc": "2.0",
  "id": 16,
  "method": "tools/call",
  "params": {
    "name": "list_tax_rates",
    "arguments": {
      "intent": "User asked which sales tax rates they have set up for invoicing.",
      "organizationId": "org_1"
    }
  }
}
```

```json Response theme={null}
{
  "jsonrpc": "2.0",
  "id": 16,
  "result": {
    "structuredContent": {
      "data": [
        {
          "id": "tax_1",
          "name": "NY Sales Tax",
          "percentage": 8.875,
          "integration": null
        }
      ],
      "pagination": {
        "hasNextPage": false,
        "pageSize": 50
      }
    }
  }
}
```

## Notes

* `percentage` is a percentage value. `8.875` means 8.875%.
* Follow `nextCursor` until `hasNextPage` is `false`. Keep the same `pageSize` and filters on every page.
