Generating the GST Input Tax Credit Report
Compare the contents of the report to the GST account balances for the period reported from the G/L. If you find discrepancies, first verify that the A/P module does not contain unposted vouchers posted from Purchasing.
Then, make sure the A/P Distribution journal has been posted to the ledger. You may have additional discrepancies if you adjusted the tax account balances manually with journal entries, or adjusted the A/P Voucher G/L GST Account Distribution records manually. Only these discrepancies are acceptable.
