I see you have removed the tax from product “Beanie”, try enabling the tax but with Zero rate, that’s my situation. You can see in my screnshots there is existing VAT but it is free (0,00 kn in my currency).

I am using default Woocommerce tax settings, the only thing I did is through code I made Zero rate to a specific user role.

if ( is_user_logged_in() && in_array( 'fizicka', $user->roles ) ) { 
    $tax_class = 'Zero Rate'; 
}

Hi Freddie,
here are some screenshots.

This is the order before splitting. You can see the first item has VAT zero rate, and the other item has normal VAT.

And this is after splitting.
As you can see, the first product has VAT just like before:

And the second product, that had Zero rate, now has VAT, and it shouldn’t.
