Subtotal Cart Price Rule excludes product tax

[bamboekeizer]

Preconditions (*)

Magento ver. 2.3.5-p1 - upgraded from 2.3.3 using composer

1. Product price includes product tax. Product tax is 21%. Shipping table rate is 6 euro.
2. Create subtotal cart price rule to have free shipping start from 99 euro. Use 0 discount either as fixed value or percentage, tried both configurations
3. Shipping costs set to 6 euro from table rates

Steps to reproduce (*)

1. As customer, add a product to the cart of 102 euro
2. Go to checkout
3. Look at the shipping costs displayed as part of the cart price
4. The shipping costs remain on 6 euro
5. The order total is product price + shipping costs = 102 + 6 euro

Expected result (*)

1. At checkout, the subtotal cart rule should evaluate the product price including tax, being 102
2. The subtotal cart rule applies the free shipping and 0 discount
3. The order total is only product price and has 0 shipping costs: 102 euro

Actual result (*)

1. At checkout, the subtotal cart rule should evaluate the product price including tax, being 102 euro
2. The subtotal cart rule does not apply the free shipping and 0 discount
3. The order total remains at product price and 6 euro shipping costs: 108 euro

We have the same issue on Magento 2.3.5-p1. For a workaround I changed the free shipping amount to the subtotal price - tax.

Also having this issue. Reproduced on 2.3.5-p1.

Temporary workaround is:
$amount / 1,{$taxrate}. So in NL (21%) with 20$ MOQ:
20/1,21 = 16,53. If you fill this in your good.

[cproboscht]

Also having this issue in 2.3.5-p1.
Got second problem which is according to this one: we have the issue, that free shipping is also calculated without tax #13392
we did not have this in 2.3.4-p2 and so we investigated changes:

found this:
vendor\magento\module-tax\Model\Sales\Total\Quote\CommonTaxCollector.php Line 596FF
$address = $shippingAssignment->getShipping()->getAddress();
$address->setBaseSubtotalTotalInclTax($baseSubtotalInclTax);
$address->setSubtotal($total->getSubtotal());
$address->setBaseSubtotal($total->getBaseSubtotal());

removed
$address->setSubtotal($total->getSubtotal());
$address->setBaseSubtotal($total->getBaseSubtotal());
for test and both issues where fixed?!

Also reproducible on 2.3.5-p2.

We worked around this by introducing a new condition option

Bumping this ticket as this is quite a critical feature.

The descriptive labels on the address attributes are just plain wrong. The first option was introduced in #21288 but this clearly was a mistake and never properly tested.

The suggestion of @k4emic is going towards the right direction with adding the correct option but the labels are still not very descriptive for the excluding tax options.

[grassst]

I also have the same problem on 2.3.5-p2.
We are using at least two tax clases. So for us changing the values in the table rate CSV is no option for us.
@k4emic can you please tell me what I have to do to get your work arround running in my system? I changed vendor/magento/module-sales-rule/Model/Rule/Condition/Address.php as you described, but where can i find this new condition to choose?

thank you!

[willtran]

I believe I am seeing the same problem.
Found inconsistency here vendor/magento/module-quote/Model/Quote/Address.php:1031

$request->setPackageValue($item ? $item->getBaseRowTotal() : $this->getBaseSubtotal());

$this->getBaseSubtotal() should be $this->getBaseTotal() or

$item-getBaseRowTotal should be $item->getBaseSubtotal()
