# Tax summary webhook and calculation requests now includes shop and presentment currency amount

As of API version `2026-01`, the `tax_summaries/create` webhook and tax calculation requests for Tax Partner Apps include additional fields for currency. These fields provide amounts in both shop currency and presentment currency. This enhancement allows tax Partners to perform calculations and reporting in the merchant's accounting currency while maintaining the customer-facing currency for display.

## What's New

The webhook and tax calculation request payloads now include new [`MoneyBag`](https://shopify.dev/docs/api/customer/2026-01/objects/MoneyBag) fields in both shop currency and presentment currency in the following locations:

1. **Sale Records** (`agreements[].sales[]`):

   * `discount_amount_set`
   * `tax_amount_set`
   * `amount_before_taxes_after_discounts_set`
   * `amount_after_taxes_after_discounts_set`

2. **Cart Line Costs** (`delivery_groups[].cart_lines[].cost`):

   * `amount_per_quantity_set`
   * `subtotal_amount_set`
   * `total_amount_set`

These fields complement the existing single-currency amount fields and are available when shops have multi-currency enabled.

### MoneyBag Structure

The new `MoneyBag` fields contain two [`MoneyV2`](https://shopify.dev/docs/api/customer/2026-01/objects/MoneyV2). Below is an example of the structure:

**Before (2025-10 and earlier):**

```json
{
    "amount_before_taxes_after_discounts": {
        "currency_code": "CAD",
        "amount": "135.00"
    }
}
```

**After (2026-01):**

```json
{
    "amount_before_taxes_after_discounts": {
        "currency_code": "CAD",
        "amount": "135.00"
    },
    "amount_before_taxes_after_discounts_set": {
        "shop_money": {
            "currency_code": "USD",
            "amount": "100.00"
        },
        "presentment_money": {
            "currency_code": "CAD",
            "amount": "135.00"
        }
    }
}
```
