VAT rate calculation doesn't reflect delivery address

[splohmer]

Bug

Hi,

I think there is one case which is currently not reflected in the VAT rate calculation for the european union. In EU, there is a scenarion where it is important where the delivery goes to. Example:

A company in germany is selling something to a company in italy with vat ids. This would be normally vat rate 0%. But if the delivery goes to germany (some country as the seller), the german tax rate needs to be applied.

I checked this in the code and I was able to identify these two functions which need to be adapted in my opinion:
html.form.class.php#load_tva
functions.lib.php#get_default_tva

I can provide the implementation for it, but would like to discuss shortly how the best way would be to implement it.

After discussion again with a tax consultant, there are many more cases in which tax rate needs to be german rate or null. Currently not possible to determine this based only on dolibarr data. Therefore I close this ticket as this has to be done manually.
