Tax, with and without shipping.

Hi Matt,

Rather than slack you on this, I thought I'd raise a discussion point.

It's a complicated one to write up, so it might take some discussion.

However firstly, I believe this is how the Tax is calculated on an order:

1. Tax is set within a pipeline by updating the OrderCalculation model. This is done using a TaxRate model which is a percentage.

2. This TaxRate (shipping/payment/total) is used on all the price calculators to calculate the right tax for the value.

3. TotalPrice includes shipping in it's value and then tax is calculated using that value.

Our dilemma is that we don't always want shipping to be taxed on the TotalPrice, for example America has different sales taxes which can and can't include shipping tax.

So two avenues I was thinking about were:

• Allow the TotalPrice Tax to be calculated with or without shipping.
• Allow an override for Tax (amount to collect) field in the order set we can set our own Tax, which at the moment is read-only.

Is this something we can do? or something you have an approach for?

Happy to explain more if needed, on here or on slack.
Gareth.

Can you not implement a shipping calculator to provide a specific tax rate just for shipping?

I guess I could try that. However I'm already setting tax on shipping to zero through the pipeline if our third party tells us to exclude it.

Its when total price tax is calculated, it includes the cost of shipping in the original figure.

So therefore shipping gets taxed too.

I need someway to stop shipping being included on the total price for the purpose of tax calculations.

To follow this up.

We used a price adjuster https://vendr.net/docs/core/1.4.0/key-concepts/price-amount-adjustments/ to change the tax at the end of the calculations.
