Hi FelicityEvelyn
The General ledger report looks at transactions posted to the account and the GST reports look at amounts allocated the GST tax code, so you'll need to look for transactions in one report but not the other. For example, General journals posted directly to the GST paid/collected account.
You can also reconcile the GST accounts in the Reconcile accounts window. Enter $0.00 as the Closing Statement balance and the date as the last day of the period. Bulk tick all transactions. Then use the Receivables with Tax report to untick the unpaid transactions. The out of balance should be the total on the GST cash report.
Please let me know if you need further help.
