Magento2: 2.2.8 Configurable product option dropdown - price difference incorrect when catalog prices are entered excluding tax

[danielpfarmer]

After upgrading to 2.2.8 we have noticed that configurable products that have only have one configurable attribute display a price increase in the dropdown of the tax amount. This seems to be only affecting stores when prices are entered excluding tax and configurable products with only one configurable attribute.

Preconditions (*)

1. Magento 2.2.8
2. Catalog Prices are EXCLUDING TAX (Stores > Configuration > Sales > Tax > Calculation Settings > Catalog Prices (Excluding Tax)

Steps to reproduce (*)

1. Create a configurable product with only one configurable attribute (e.g color).
2. Assign simple products to the configurable, and set all simples to be the same price.
3. Load configurable product page.
4. View options in the configurable attribute.

Expected result (*)

1. The attribute dropdown does not show an increase in price as all attached simples are the same price and tax is already rendered in the final price at the top of the page.

Actual result (*)

1. Observe that the dropdown displays an incorrect increase in price. It adds on the tax amount of the product onto the price increase when this is already rendered in the product final display price at the top of the page.

Magento 2.2.6 (Correct)

Magento 2.2.8 (Incorrect)

In this example, each simple product was added into Magento with a price of £150 and a special price of £122.49. The tax settings then add on an additional £24.50 (20% VAT).

Hi @danielpfarmer thank you for you report, this is expected behavior introduced in -> https://github.com/magento/magento2/pull/17695

[hostep]

@engcom-backlog-nazar: closing this makes no sense, since this ticket is about seeing the taxes in the dropdown. This might be a regression introduced by #17695.

[ghost]

@hostep ok, the core issue that

EXCLUDING TAX (Stores > Configuration > Sales > Tax > Calculation Settings > Catalog Prices (Excluding Tax)

does not affect in prices of dropdown attribute ?

[hostep]

@engcom-backlog-nazar: not sure, haven't looked into the details yet, just reopened the issue because it looked like it was closed for the wrong reason.

Maybe @danielpfarmer can answer your question.

[danielpfarmer]

Hey @hostep @engcom-backlog-nazar

Yes this affects stores which have their prices inserted in the backend excluding tax, and then display prices including tax. Tax is added using the tax rules.

The problem:

Magento displays the product price including tax on the pdp.

The dropdown then shows a price increase, in this case of £24.50, which shouldnt be there as it is the product tax amount and is already included as part of the product price already displayed on the pdp.

This would make the customer think that the price is £146.99 + £24.50 (£171.49) when it isn't. It is only £146.99 in total.

Cheers

[hostep]

Good point @Naitaes. Sometimes the version mentioned in those automated comments is not correct unfortunately.
However it looks like it got included in Magento 2.2.10: https://github.com/magento/magento2/blob/2.2.10/app/code/Magento/ConfigurableProduct/view/frontend/web/js/configurable.js#L376

I am having the same issue in Magento ver. 2.2.2. Is there any quick tip to fix this in v2.2.2 instead updating the whole magento version?
