Hi Awije,

We experienced this problem.

At first, an account that is not marked as tax account, was setup in "Posting Control Navigator" for posting type TX2.
When the expense's voucher was updated to GL, no transactions were created in "Tax Transactions".
Then we changed accounts in "Posting Control", so that a tax account was used instead.
After this, we created a new expense report, authorized it and updated the voucher to GL. This time, tax transactions were created.
