# Setting up tax exemptions
As part of the process of configuring tax exemptions, you can set a customer's [type](#customer-type), along with arrays of [tax identifiers](#tax-identifiers) and [tax certificates](#tax-certificates)
## Customer type
For details on how a use the [customer's ](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers)`type` to calculate taxes, refer to the [Setting the customer type](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/setting-the-customer-type) page.
## Tax identifiers (legacy)
{% hint style="warning" %}
In versions `2020-12-17` and earlier, use the legacy features described in this section to manage tax identifiers. If you're on versions `2021-02-23` and later, refer to the [Tax identifiers](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/tax-identifiers) page.
{% endhint %}
Some customers have tax identifiers that allow them to purchase zero-rated goods. If you want customers to apply tax identifiers to their purchases, your integration must first [add the tax identifier to the customer's record](#adding-tax-identifiers-to-customers). Once that operation is successfully completed, Digital River automatically attaches the tax identifier to the transaction whenever the customer creates an applicable [registered checkout](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/using-the-checkout-identifier#registered-checkouts-or-invoices).
### Adding tax identifiers to customers
When you [create ](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers#customers)or [update a customer](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers#customers-id-1), you can add one or more `taxIdentifiers[]`. For each tax identifier, you want to add, specify a `type` and a `value`. The [enumerated `type` values](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/tax-identifiers#supported-tax-identifiers) typically consist of a lowercase, two-letter country code. This `value` is dependent on the format used in each country.
{% hint style="info" %}
You can use the [tax identifier element](https://docs.digitalriver.com/digital-river-api/developer-resources/reference/elements/tax-identifier-element) to validate customer-supplied data.
{% endhint %}
The following shows how to add multiple tax identifiers in a [`POST /customers/{id}`](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers#customers-id-tax-identifiers-taxid) request:
{% tabs %}
{% tab title="POST /customers/{id}" %}
```
curl --location --request POST 'https://api.digitalriver.com/customers/987654321' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ' \
--data-raw '{
"taxIdentifiers": [
{
"type": "uk",
"value": "GB243609761"
},
{
"type": "nl",
"value": "NL002458380B62"
}
]
}'
```
{% endtab %}
{% endtabs %}
The response returns `taxIdentifiers[]` that are now saved to the customer's record:
{% tabs %}
{% tab title="Customer" %}
```javascript
{
"id": "987654321",
...
"taxIdentifiers": [
{
"type": "uk",
"value": "GB243609761"
},
{
"type": "nl",
"value": "NL002458380B62"
}
],
...
}
```
{% endtab %}
{% endtabs %}
### Replacing a tax identifier
A [customer](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers) can't have multiple `taxIdentifiers[]` of the same `type`. So, if you'd like to attach a new tax identifier to a [customer ](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers)with the same `type` as a saved tax identifier, you must first delete the existing object.
To do this, submit a `POST /customers/{id}` request and set the `value` you'd like to replace to `""`.
{% hint style="success" %}
Make sure you format `value` without white spaces.
{% endhint %}
{% tabs %}
{% tab title="POST /customers/{id}" %}
```
curl --location --request POST 'https://api.digitalriver.com/customers/987654321' \
--header 'Authorization: Bearer ' \
--header 'Content-Type: application/json' \
--data-raw '{
"taxIdentifiers": [
{
"type": "nl",
"value": ""
}
]
}'
```
{% endtab %}
{% endtabs %}
Then submit another `POST /customers/{id}` request with the original `type` and an updated `value`:
{% tabs %}
{% tab title="POST /customers/{id}" %}
```
curl --location --request POST 'https://api.digitalriver.com/customers/987654321' \
--header 'Authorization: Bearer ' \
--header 'Content-Type: application/json' \
--data-raw '{
"taxIdentifiers": [
{
"type": "nl",
"value": "NL001868214B01"
}
]
}'
```
{% endtab %}
{% endtabs %}
### Supported tax identifiers
For a complete list, refer to the [supported tax identifiers](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/tax-identifiers#supported-tax-identifiers) section on the [Tax identifiers](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/tax-identifiers) page
## Tax certificates
You can build your integration so [eligible customers](#what-customers-are-eligible) with [valid tax certificates](#how-we-validate-tax-certificates) can make tax-exempt purchases.
To configure certificates for use in [eligible transactions](#what-transactions-are-eligible), you must:
* [Collect tax exemption information from customers](#collecting-tax-certificate-information)
* [Create a tax certificate file](#creating-tax-certificate-files)
* [Add the certificate to the customer](#adding-a-tax-certificate)
Digital River also allows you to [associate multiple tax certificates with a single customer](#adding-multiple-tax-certificates-to-a-customer).
### What customers are eligible
Usually, customers who want to use a tax certificate must be a government agency, a non-profit organization, or a product reseller based in the United States.
In the US, almost all product end users are taxed. The primary exceptions are government agencies and not-for-profits. Businesses are typically only tax-exempt when reselling a product.
### What transactions are eligible
In the Digital River APIs, tax certificates can only be used in [registered checkouts](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/using-the-checkout-identifier#registered-checkouts-or-invoices) and [registered checkout-sessions](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/drop-in-checkout-sessions/checkout-sessions-basics#registered-customers). Additionally, the [customer's](https://www.digitalriver.com/docs/digital-river-api-reference/#tag/Customers) record must contain a valid `taxCertificates[]` whose [`taxAuthority`](#tax-authority) matches the transaction's `shipTo.address.state` or `billTo.address.state`. If the purchase contains [physical products](https://docs.digitalriver.com/digital-river-api/product-management/creating-and-updating-skus#how-products-are-specified-as-physical-or-digital), Digital River compares `taxAuthority` to [`shipTo.address.state`](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/providing-address-information#ship-to-address). In transactions that only contain [digital goods](https://docs.digitalriver.com/digital-river-api/product-management/creating-and-updating-skus#how-products-are-specified-as-physical-or-digital), we compare `taxAuthority` to [`billTo.address.state`](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/providing-address-information#bill-to-address).
For example, the following [customer](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers) has [multiple tax certificates](#adding-multiple-tax-certificates-to-a-customer). Since the `taxAuthority` of one is `MN` and the other is `WI`, if this customer requests to have physical products shipped to Minnesota or Wisconsin, that transaction is tax-exempt. However, if the customer specifies a shipping address other than these two states, Digital River applies taxes.

### How we validate tax certificates
Since Digital River is the [reseller of record](https://docs.digitalriver.com/digital-river-api/general-resources/glossary#merchant-of-record-seller-of-record-mor-sor), we subject a [customer's ](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers)`taxCertificates[]` to a verification process. When customers supply their certificate during a checkout, we issue a temporary exemption for that transaction.
If we determine that a customer's document isn't a valid, state-accepted exemption certificate, we mark the account as in review. While in this state, certificates can't be used to make tax-exempt purchases.
We then email the customer to request additional documentation. If the customer fails to provide a valid certificate, we send another follow-up email. If that request doesn't produce the necessary documentation, we move the certificate into an unapproved state. This means it won't be applied to future transactions.
{% hint style="info" %}
On your site, we recommend that you inform customers that they might receive a follow-up email from Digital River requesting more information about their tax certificate.
{% endhint %}
On the other hand, if our review determines that a certificate is valid, we automatically apply a tax exemption to all future [eligible transactions](#what-transactions-are-eligible). However, once the tax certificate's [`endDate`](#start-and-end-dates) elapses, that exemption no longer applies.
No methods currently exist to query the APIs and determine the status of a tax certificate. Additionally, at this time, you can't subscribe to [webhook events](https://docs.digitalriver.com/digital-river-api/order-management/events-and-webhooks-1/events-1) that notify you when a certificate's state has been updated.
### Collecting tax certificate information
If your site intends to offer tax-exempt purchases, provide a form for customers to enter their certificate information. The form must contain fields that collect:
* The name of the company/organization/agency that was issued the tax exemption
* The name of the tax authority (i.e., the US state) that issued the certificate
* The start and end dates of the tax exemption
You'll also need to allow customers to upload a copy of their certificate. Restrict the format of the uploaded file to PDF, JPG, or PNG and its size to 10 MB or less.
Certificates of exemption must be addressed to Digital River. This is because we act as the [reseller of record](https://docs.digitalriver.com/digital-river-api/general-resources/glossary#merchant-of-record-seller-of-record-mor-sor). The correct address depends on the [selling entity](https://docs.digitalriver.com/digital-river-api/integration-options/checkouts/creating-checkouts/selling-entities) that is facilitating the transaction. So, during the checkout process, use `sellingEntity.id` or `sellingEntity.name` to determine the appropriate address disclosure to display to customers:
| `sellingEntity.id` | `sellingEntity.name` | Address disclosure |
| ------------------ | --------------------- | -------------------------------------------------------------------------------------------------------------------------------- |
| `DR_INC-ENTITY` | `Digital River, Inc.` |
Please address exemption certificates to:
Digital River, Inc.
10380 Bren Road West
Minnetonka, MN 55343
|
| `C5_INC-ENTITY` | `DR globalTech Inc.` |
Please address exemption certificates to:
DR globalTech, Inc.
10380 Bren Road West
Minnetonka, MN 55343
|
After you collect the document, use it to [create a tax certificate file](#creating-tax-certificate-files).
### Creating tax certificate files
Once customers upload their tax certificate, submit a [`POST /files`](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/files#files-1) request to create a file in Digital River's system. In the request, make sure you define [`file` ](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/files/file-basics)and set [`purpose` ](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/files/file-basics#file-and-purpose)to `tax_document_customer_upload`.
From the response, retrieve `id` and use it to [add the tax certificate to the customer](#adding-a-tax-certificate).

### Adding tax certificates to existing customers
After [creating a tax certificate file](#creating-tax-certificate-files), pass the customer's unique identifier as a path parameter in a [`POST /customers/{id}`](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/files#files-id-1). In the body of the request, use `taxCertificate` to send the information your form collected, as well as the identifier of the file.
{% tabs %}
{% tab title="Update customer" %}
```
curl --location --request POST 'https://api.digitalriver.com/customers/541670080336' \
--header 'Content-Type: application/json' \
...
--data-raw '{
"taxCertificate":{
"companyName": "Acme Inc",
"taxAuthority": "MN",
"startDate":"2021-04-07T13:47:13Z",
"endDate":"2025-04-07T13:47:13Z",
"fileId": "9d149880-7306-49da-b37b-8440649ae9c2"
}
}'
```
{% endtab %}
{% endtabs %}
#### Company name
The `companyName` should indicate the name of the company or organization granted the tax exemption.
#### Tax authority
Since tax certificates only apply to US-based customers, `taxAuthority` corresponds to the issuing state. The value you assign should be formatted to conform to the [USPS two-letter state and possession abbreviation standard](https://pe.usps.com/text/pub28/28apb.htm). These are the same abbreviations used in the [ISO 3166-2 subdivision codes](https://www.iso.org/obp/ui/#iso:code:3166:US).
#### Start and end dates
The `startDate` and `endDate` values correspond to the issue and expiration dates of the tax certificate, respectively.
{% hint style="info" %}
In the request, make sure `startDate` and `endDate` adhere to the [date and time format used in the Digital River APIs](https://app.gitbook.com/s/ZrhMyLX5esFYS64lNWVW/digital-river-api-reference-guide/api-structure#dates-and-times).
{% endhint %}
Tax certificates can be difficult to interpret. As a result, your customers might be unable to determine appropriate input dates. If this is the case, define `startDate` as the first date of the current month and `endDate` as the last date of the current month. This allows us time to review the certificate, determine its validity, and set the applicable dates.
#### File identifier
Retrieve the identifier of the [tax certificate file](#creating-tax-certificate-files) that you created and use it to define `fileID`.
### Verifying the tax certificate exists
Once you [add a tax certificate to the customer's record](#adding-a-tax-certificate), send a [`GET /customers/{id}`](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers#customers-id) request and parse the response to verify the object has been successfully added to `taxCertificates[]`.

}
],
"locale": "en_US",
"type": "business"
}
```
{% endtab %}
{% endtabs %}
### Adding multiple tax certificates to a customer
You can only send one `taxCertificate` in a [`POST /customers`](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers#customers) or [`POST /customers/{id}`](https://app.gitbook.com/s/x8fSFzVR3sg0TsNWwwVz/customers#customers-id-1) request. But a customer can have multiple `taxCertificates[]`.
At checkout-time, Digital River determines which (if any) are [applicable](#what-transactions-are-eligible).
