Withholding tax and suspense account

How do I account for withheld tax on an invoice in manager? I usually receive the full invoiced amount without deducting the tax amount this ends up giving me wrong balances when doing my bank reconciliation.

Then where should the Cash into the petty cash account go? mine goes to the suspense account which is not right,

Not sure I understand. If you receive full invoiced amount, how do you end up with wrong balances again? Can you give some specific example?
