Deposits in transit are ordinary when cash is recorded the day it is received but the bank posts it the next clearing day. Trouble starts when the same deposit sits open for more than a few business days without a matching bank credit.
Begin with the deposit slip or remittance advice date, not the ledger posting date alone. Match amount, then payer reference, then bank credit date. If the amount matches but the payer reference does not, treat it as a separate investigation rather than forcing the match.
Age the open list weekly during close week. Items older than five Taipei banking days deserve a named owner and a follow-up note. Items older than thirty days usually need either a bank inquiry letter or a reclassification discussion with the controller.
During a bank reconciliation audit we list each deposit in transit with age, evidence status, and a recommended action. That list becomes the clearance plan rather than a static footnote on the reconciliation worksheet.
