Generating the PST Input Tax Credit Report
To verify the report, compare the contents of the report to the PST account balances for the period reported from the G/L. If you find discrepancies, first verify that A/P does not contain unposted vouchers from Purchasing.
Then, make sure that 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 PST Account Distribution records manually. Only these discrepancies are acceptable.
