Order totals showing wrong way around

Question

How can I change the position of the order totals (incl. tax / excl. tax) in the tax calculation? As it should show the total including tax below the total excluding tax but at the moment it does not.

Answer 1

Other than the single totals (subtotal, tax, shipping, discount) which you can reorder in Stores > Configuration > Sales > Sales > Checkout Totals Sort Order, the grand totals are hard coded in the template

Magento/Tax/view/frontend/web/template/checkout/cart/totals/grand-total.html

<tr class="grand totals incl">
    <th class="mark" scope="row">
        <strong data-bind="i18n: inclTaxLabel"></strong>
    </th>
    <td data-bind="attr: {'data-th': inclTaxLabel}" class="amount">
        <strong><span class="price" data-bind="text: getValue()"></span></strong>
    </td>
</tr>
<tr class="grand totals excl">
    <th class="mark" scope="row">
        <strong data-bind="i18n: exclTaxLabel"></strong>
    </th>Magento/Tax/view/frontend/web/template/checkout/summary/grand-total.html
    <td data-bind="attr: {'data-th': exclTaxLabel}" class="amount">
        <strong><span class="price" data-bind="text: getGrandTotalExclTax()"></span></strong>
    </td>
</tr>

Override this template in your theme and change the order of these two <tr> table rows.

This template is for the cart. For the checkout summary, do the same in Magento/Tax/view/frontend/web/template/checkout/summary/grand-total.html
