all IDs are configured to use Autogenerated HIGHLOW type.

Your class definition looks good.
The only idea I have about your error is that you are generating new TaxCode objects that will get individual ids because of the high-low key generator.
To generate a new Product you have to get the existing TaxCode out of the database using a query. This is the only object that you should assign to the product TacCode property. If you generate new objects instead, even if you set the right id, the objectscope.Add() call will overwrite that with a new generated id.
All the best,
