Including Tax - wrong totals and subtotals displayed on cart and checkout

[ivanweiler]

Preconditions

1. PHP 7.0.8, MySQL 5.7.13
2. Magento 2.1.2

Steps to reproduce

1. Navigate to Stores -> Configuration -> Tax
2. Set Default Tax Classes, Default Tax Destination Calculation
   (have some tax preconfigured for this)
3. Calculation Settings -> Catalog prices: Including Tax (prices are entered with default tax on products)
4. Shopping Card Display Settings -> Display Prices: Including Tax
5. Shopping Card Display Settings -> Display Subtotal: Including Tax
6. Shopping Card Display Settings -> Include Tax in Order Total: Yes

Expected result

1. Total on Cart page should include tax
2. Product prices, subtotals and totals on Checkout page should include tax. Final total should be correct, displaying what customer is paying.

Actual result

1. Cart page is displaying total without tax
2. Checkout page is displaying product prices, subtotals and total without tax. Tax is displayed separately, but never added to total, making final total wrong.

Some countries like Croatia have fixed predefined tax and prices are entered with tax included on products. Default tax country is set and all prices should be displayed Including Tax through the system.

Magento is ignoring those settings on cart and checkout, so customers see one total (without tax), but they are charged with another (with tax) when placing order!!

For example, I see that /totals-information API on cart is always returning grand_total - tax, ignoring above configuration, and javascript is just displaying that value, even though grand_total in db is correct.

Further analysis shows, if I set "Include Tax in Order Total: No", then total is right and tax is included in total (when product prices include tax like explained above).
I'm not sure if I don't understand this setting or it's a bug?

But this also works only on some setups and not another ..
Magento_Tax module rewrites some UI components from its layouts. For example, if Tax module is enabled, grand-total.html should be loaded from Tax module and not Checkout module.

However, I have live site with php 7.0.11 where grand-total.html is loaded from Checkout module, displaying wrong total. It's like UI component rules defined in Magento_Tax layouts are ignored.

I think this is related to how modules are sorted in app/etc/config.php, because Magento_Tax is sometimes loaded before Magento_Checkout (doesn't work) and sometimes after (works).

I have the same issue also. Making sure that Mage_Tax module is loaded after Mage_Checkout resolves issue for cart, but Onestep checkout (Magento standard, not a third-party module) still displays shipping and items in summary excluding tax.

Is it possible to change the loading sequence of the core modules without touching the core files?

Edit: I created my own custom module with only module.xml + registration.php files in module.
In the module.xml file I added:
<sequence> <module name="Magento_Checkout"/> <module name="Magento_Tax"/> </sequence>

Then the modules got the correct order in config.php and checkout worked as expected.

Under tax -> shipping settings have you set the origin country to the correct country?

just to share, I had a similar issue where the prices in the catalogue, cart and orders were fine, but the sidebar on the checkout refused to add tax to the order summary - turned out to be an issue with layout file Magento_Checkout/layout/checkout_index_index.xml from the Luma theme. The components loading in the sidebar were that of Magento_Checkout/js/view/summary/grand-total instead of Magento_Tax/js/view/checkout/summary/grand-total. Compare yours with the master copy (https://github.com/pepe1518/magento2/blob/master/vendor/magento/module-tax/view/frontend/layout/checkout_index_index.xml) to confirm if you have the same issue.

Similar issue in MCE 2.1.3.

My goal was to show the same product on two websites (once including tax, once excluding tax, e.g. on "checkout/cart" page).

I have added two modules with sequence dependency to "Magento_Tax", which results in a different module loading order in "app/etc/config.php" ("Magento_Checkout" after "Magento_Tax"). The (js/knockout) file grand-total.html was included from "Magento_Checkout" not from "Magento_Tax" module, because Layout XML merging of both modules was done in the wrong direction.

Magento Team Todos:

1. Review all core modules for correct or missing module sequence dependencies.
2. Refactor module sequence (config.php) generation.

Regarding 2): Some strange behaviour occured here: Adding a module with a sequence entry to one Magento core module changes also loading order of other Magento core modules...

BTW: I had also an issue with loading correct Magento_Tax configuration, where the scope is restricted t o "website" scope. It looks like Magento can not fetch "parent" setting if scope "store" and Store model is used to fetch the config information which is configured for scope "website".

Unfortunately, I could not reproduce the issue as you described it. Can you reproduce this issue on latest version of Magento2?

[swayoleg]

I can reproduce this issue in latest m2 version.
