Hi there, is it about a feature request to automatically determine type based on customer address?

Hey Jack. I want to provide the customer's Tax ID to the Tax Calculation

Yet it requires me to set the "type" of the Tax ID

Say I'm based in France and selling internationally. How would I know which "type" of Tax ID my customer has entered?

[elfin eagle]

https://stripe.com/docs/billing/customer/tax-ids#supported-tax-id you can find the list of tax ID types here

Okay but how would I know wich Tax ID type to use?

my first thought was to use take the customer country, but some countries have multiple Tax IDs. Canada even has 6

That's a local regulations, you might want to check with your compliance team.

But Stripe Checkout has a tax_id_collection flag that doesn't require to pass a Tax ID Type

it enables the option for the customer to select "I'm purchasing as a business" and they can enter a tax ID then

Right, but how does Stripe determine the tax id type based on the tax id?

[chilly lion]

the country the user picks

[lyric lion]

But for example Canada has 6 tax id types

I guess I can use the country and then the tax id format to determine the type

Just seems a bit strange that Stripe doesn't handle it

[chilly lion]

not sure what you mean

the ID the customer enters on Checkout appears here : https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-customer_details-tax_ids when the CheckoutSession is complete

so you know the type

I'm building a custom payment flow, so we will collect the tax id ourselves and pass it to the tax calculations api

but to pass it to the tax calculations api we also need to provide the tax id type

[chilly lion]

then you need to ask the customer what their country/tax ID type is I suppose

that's how we do it inside our own product
