Product custom option pricing ignores tax calculation settings

[bentideswell]

Preconditions and environment

• Magento version: 2.4.6

Steps to reproduce

1. Create new simple product and set price as 0.00 and add a custom option with a fixed price of $10.00
2. Navigate to Stores > Configuration > Sales > Tax
3. Change 'Calculation Settings > Catalog Prices' to 'Includes Tax'
4. Change 'Price Display Settings > Display Product Prices in Catalog' to 'Including Tax'
5. Change 'Shopping Cart Display Settings > Display Prices' to 'Including Tax'
6. Change 'Default Tax Calculation Destination' to 'United Kingdom'
7. Setup a 20% tax rule that is auto applied to the United Kingdom.
8. Browse to the product on the frontend and view the option price

Expected result

The website is configured to input prices including tax and then display them including tax. The product has a price of $0.00 and the option has a price of $10.00 so the option should display at $10.00. When added to the cart with this option, the price should be $10.00.

Actual result

The option price is $12.00 (assuming a 20% tax rate), which is incorrect. Product pricing is configured to be entered including tax so the $10 entered for the option should not have tax added to it.

Additional information

I first noticed this bug on 2.4.3-p3 but have tested this on a 2.4.6 CE install for this bug report and confirm it is still there.

When product prices are entered inculding tax and configured to display including tax, tax is added to option price, which is incorrect as this has been entered including tax.

I have since noticed that this bug only exists when setting the tax rule for the UK (which is what my client uses). When using the US, this does not occur. The only difference here potentially is the State field.

As a workout around users must enter their product custom option prices excluding tax. This is confusing as all other pricing on the site is entered inclusive of tax.

Issue recreated using the provided Magento instance here

You can see option price being displayed as $12.00 but price was entered as $10.00.

I had to change the tax country and default country to the United Kingdom as setting it as the United States didn't trigger the error. I've edited the initial comment/steps to include this. I've also tried using France and Ireland and both also had the bug present. Only the US did not.

@engcom-Bravo If it's helpful, I have an instance here that is configured to replicate the bug.

The option price was entered as $10 and product pricing configured to be entered inclusive and display inclusive, so it should display as $10, but you can see it as $12 in the custom options dropdown.

@engcom-Bravo did you set the price display and price calculation settings to Include Tax? This is the key part that causes the issue.

I can reconfigure your instance to show the error, however the instance is no longer available

I've tested and I had missed a step which I thought wasn't relevant but was. Here are the updated steps:

Updated Steps to reproduce

• Create new simple product and set price as 0.00 and add a custom option with a fixed price of $10.00
• Navigate to Stores > Configuration > Sales > Tax
• Change 'Calculation Settings > Catalog Prices' to 'Includes Tax'
• Change 'Price Display Settings > Display Product Prices in Catalog' to 'Including Tax'
• Change 'Shopping Cart Display Settings > Display Prices' to 'Including Tax'
• Change 'Default Tax Calculation Destination' to 'United Kingdom'
• Setup a 20% tax rule that is auto applied to the United Kingdom.
• Flush the full page cache
• Browse to the product on the frontend and view the option price

The extra step is setting the 'Shopping cart Display Settings > Display Prices' to 'Including Tax' and flushing the full page cache (or just resaving the product).

I wouldn't have thought this setting would affect the product view page as we are not in the cart yet, but setting this and flushing the cache changes the option price to $12.00.

You can see this here on the latest instance I generated (if it's still up) but here's a screenshot:

@bentideswell

After a little research on the functionality, I can conclude that if the taxes for origin country of shipping, set in the configuration, and the default destination country in the tax calculation settings are different, then the customer tax will be added to the amount of product ( Instead of a store tax ).

Perhaps the option "Cros Border Trade" can provide the desired calculations. Or set the original country of delivery as UK (if the store does not intend to trade cross-border)

@engcom-Bravo Just want to clarify: is this really a bug, or this behavior is expected?
