When creating a new product, there is no need to fill in an account. When invoicing the product, the account is taken from the product category. However, no tax code can be filled in on a product category. It is possible to specify a default tax code on the account, and this would actually work well for me.

The only issue I have is that it seems the default tax codes in accounting settings cannot be set to blank. The codes filled in there are used as defaults when creating a new product and override the value specified on the account. Admittedly this is not a huge problem as the only thing that needs to be done is remove the values on every new product, but people forget this from time to time.

So I'm wondering:

• Can de default tax codes in accounting settings be set to blank?

• Is there a drawback/issue with not setting the vat on every product separately?

• Related point: when importing data from a csv, is it possible to set tax (or any other one2many field) to blank, so that any pre-existing values are removed and no defaults are used?
