One-Stop Shop

To be able to facilitate the One Stop Shop (OSS) Scheme, you need to specify the following settings for your Marketplace and relevant sellers.

First, you need to ensure that you have created an EU region to represent the European Union.

Marketplace regional settings

You need to specify the following fields in the Marketplace's regional settings:

Field	Description
`taxation.physical.special_tax_registration`	Indicates the tax scheme that applies. Specify `VOEC` for the EU.
`oss_member_state_of_identification`	Specify the member state country where the OSS number is registered.
`oss_registration_number`	Specify the OSS number, if any, that will be used by sellers in this region.

Example:

{
     "settings": [
          {
               "value": {
                    "taxation": 
                    "regions": {
                         "EU": {
                              "taxation": {
                                   "physical": {
                                        "special_tax_registration": "OSS",
                                        "oss_member_state_of_identification": "DE",
                                        "oss_registration_number": "DEF345667"
                                   }
                              }
                         }
                    }
               }
          }
     ],
}
'

Marketplace country and subdivision settings

For the Marketplaces country setting, you need to ensure that the taxation.physical.is_seller_registered setting is set for the subdivision.

For country subdivisions, you need to ensure that the taxation.is_enabled setting is set for the subdivision.

Example:

{
     "settings": [
          {
               "value": {
                    "countries": {
                         "GB": {
                              "is_domestic": true,
                              "taxation": {
                                   "physical": {
                                        "is_seller_registered": true
                                   }
                              },
                              "country_subdivisions": {
                                   "NI": {
                                        "taxation": {
                                             "is_enabled": true
                                        }
                                   }
                              }
                         }
                    },
                    "regions": {
                         "EU": {
                              "taxation": {
                                   "physical": {
                                        "special_tax_registration": "OSS",
                                        "oss_member_state_of_identification": "DE",
                                        "oss_registration_number": "DEF345667"
                                   }
                              }
                         }
                    }
               }
          }
     ],
}

Field	Description
`physical.oss_member_state_of_identification`	The EU member state where the OSS number was registered.
