# `Stripe.Params.InvoiceCreatePreviewParams.CustomerDetails.Tax`
[🔗](https://github.com/jeffhuen/tiger_stripe/blob/main/lib/stripe/params/invoice_create_preview_params.ex#L105)

Nested parameters.

# `t`

```elixir
@type t() :: %Stripe.Params.InvoiceCreatePreviewParams.CustomerDetails.Tax{
  ip_address: map() | nil
}
```

* `ip_address` - A recent IP address of the customer used for tax reporting and tax location inference. Stripe recommends updating the IP address when a new PaymentMethod is attached or the address field on the customer is updated. We recommend against updating this field more frequently since it could result in unexpected tax location/reporting outcomes.
