Hello,

The following issue is already known on GitHub (https://github.com/odoo/odoo/issues/10855). As there is no movement I wanted to ask this community if someone has an idea on how to fix the following issue:

It's not possible for accountant to deliver VAT declaration if PoS is used:

Steps to reproduce on Odoo9:

1. Create a Product with default demo sale and purchase VAT (15%) ;
2. Open a PoS session;
3. Sell the product (qty = 1) ; pay the Order ;
4. Close the session and post entries;
5. Check generated sale accounting entries ; Open the move.line related to the sale.

Current behavior:

• 'tax_ids' is not defined

Expected behavior:

• 'tax_ids' = the vat of the product
  
  

I identified the following code snippet as potential problem:

point_of_sale/point_of_sale.py

insert_data('product', {
                    'name': name,
                    'quantity': line.qty,
                    'product_id': line.product_id.id,
                    'account_id': income_account,
                    'analytic_account_id': self._prepare_analytic_account(cr, uid, line, context=context),
                    'credit': ((amount>0) and amount) or 0.0,
                    'debit': ((amount<0) and -amount) or 0.0,
 'partner_id': order.partner_id and self.pool.get("res.partner")._find_accounting_partner(order.partner_id).id or False
                })

We suppose by adding "tax_ids" it should work:

'tax_ids': tax_var,

The only difficulty we have is in getting the variable for the tax_ids. 

Does anybody of you have an idea?
