If we pay a person commission only for work he brings us. He pays his own tax etc. how do I set this up in quickbooks ? is it an expense or somewhere else?

I'll help you record the commission, Pat34.

It seems like you don't need to set them up as an employee since they pay their taxes. You can create an expense or cheque to record the commission or transaction. Here's how:

1. Click the New or Plus sign (+) button.
2. Select Expense or Cheque.
3. Fill in the necessary fields.
4. Click Save and close.

As always, I'd suggest reaching out to your tax adviser on the best way to categorise this transaction.
