Taxes at Order Creation

Taxes are an essential element of an order. In addition to static configurations, IOM also supports variable tax rates and tax location rules at order creation. This is required for several markets, e.g. in the EU (see VAT in European Commission | Buying goods online coming from within the European Union) or US, where rules can be complex and can change at any time.

This section describes in short how to create orders with the old and the new approach for taxes.

Possible Tax Data at Order Creation

Starting from Reference - IOM REST API - Order 2.2 taxes support a rate and a location.

The following table describes useful combinations that may be submitted on order creation.

#JSON of Tax-model
1{"taxType": "FullTax", "amount": 20}
2{"taxType": "FullTax", "location": "US/Baltimore", "amount": 20}
3{"taxType": "FullTax", "rate" : 6.5, "amount": 20}
4{"taxType": "carbon dioxide tax", "rate" : 3.75, "amount": 12.3", "location": "USA"}

Info

If the location is a country, it is recommended to use its ISO-3-code.

Mapping Rules

The following list of rules describes how the tax will be stored depending on the given data of the REST API and the configuration of the shop.

Depending on the configuration and the available information, either a strict validation of predefined taxes is used or (almost) anything will be accepted.

For Tax-model see the table above.

Tax-model

Rule/ Mapping

#1 or #2Without rate, the tax must be pre-configured in TaxDO, with a valid tie range. Otherwise, the order will be refused.
#1 or #3

Without location it will be selected during the order validation. It will always be set to a country code (ISO 3166-1 alpha-3).

Depending on the configuration, the location will be selected as follows:

  • ShopDO.shippingCountryTaxMapping IS NOT set, ShopDO.country will be used.
  • ShopDO.shippingCountryTaxMapping IS set:
    • For all taxes located within a shipping bucket, the country of the shipping bucket's shipping address will be used
    • For all taxes located outside a shipping bucket (e.g.: order charges), the country of the first shipping bucket's shipping address will be used.

      Info

      This is an arbitrary choice, and customers with shipping buckets to different countries should in fact always include the location as a tax attribute.

#3 or #4

Type and rate provided.

If no corresponding entry in TaxDO is found, a new one will be created automatically (and possibly a new tax-type too).
