try this way it definitely worked :
classSaleOrderLine (models.Model):
_inherit = 'sale.order.line'
​ @api.onchange ( 'tax_id' )
def  _onchange_tax_id ( self ):
if  self .order_id.order_line:
for line in  self .order_id.order_line:
origin_line = line._origin
origin_line.tax_id = [( 6 ,  0 ,  self .tax_id.ids)]

Hi,
You can use the on-change functionality.
For example:
class SaleOrder(models.Model):
_inherit = 'sale.order'
@api.onchange('tax_id')
def _onchange_tax_id(self):
for line in self.order_line:
line.tax_id = self.tax_id
Hope it helps
