Shipping total is not including tax

[edinskeja]

Bug report

I have activated "includes_tax" feature and products are working but shipping tax seems to be only working inside "shipping_methods" and not on the "shipping_total".

"shipping_total": 7920,

 "shipping_methods": [
        {
            "id": "sm_01H97SZZ0VW6A36G4DJT6FZFB5",

Similar issue here.

I enabled tax inclusive pricing and added shipping methods. The UI indicates tax inclusive prices:

When fetching shipping methods by cart id (medusaJS) I get:

q]   {
[q]     id: 'so_01HCEMWQZ7YRBC2S99X170MCE3',
[q]     created_at: '2023-10-11T05:55:57.517Z',
[q]     updated_at: '2023-10-11T05:55:57.517Z',
[q]     deleted_at: null,
[q]     name: 'PostPac Economy',
[q]     region_id: 'reg_01HAHQYYPKTABSH3GZEDCCGGN2',
[q]     profile_id: 'sp_01HAH9PEC7JZFBR8JNWA7RQGM9',
[q]     provider_id: 'manual',
[q]     price_type: 'flat_rate',
[q]     amount: 900,
[q]     is_return: false,
[q]     admin_only: false,
[q]     data: { id: 'manual-fulfillment' },
[q]     metadata: {},
[q]     includes_tax: false,
[q]     profile: {
[q]       id: 'sp_01HAH9PEC7JZFBR8JNWA7RQGM9',
[q]       created_at: '2023-09-17T10:06:36.169Z',
[q]       updated_at: '2023-09-17T10:06:36.169Z',
[q]       deleted_at: null,
[q]       name: 'Default Shipping Profile',
[q]       type: 'default',
[q]       metadata: null
[q]     },
[q]     requirements: [ [Object] ],
[q]     price_incl_tax: 969,
[q]     tax_rates: [ [Object] ],
[q]     tax_amount: 69
[q]   },

You can see that includes_tax: false,.

When I attach this shipping method to a cart, the total prices are not calculated correctly.

I am using the latest version of medusa.
