Tax not excluded from revenue

Hey all,

I have the option “exclude tax from revenue” checked, but my “revenue” data in GA4 is showing the total cost of the product.

In our store, we show the total cost of product with tax.

I hoped that with this option it will show only the product cost without VAT.

The option “exclude shipping from revenue” works great.

Can anybody help me fix this?

Really thanks for your time and work!
