Learn what causes a reconciliation discrepancy, how to trace changed or missing transactions, and why unexplained adjustments can hide bookkeeping errors.
A reconciliation discrepancy is an unexplained difference between a financial statement or other independent record and the corresponding balance or activity in the accounting records. The term can also describe a beginning-balance difference caused when a previously reconciled transaction is later changed, deleted, duplicated, or moved.
A discrepancy is a signal to investigate. It is not itself an expense, income item, or permanent adjustment category.
Not every difference is an error. A bank reconciliation can properly include an outstanding check or deposit in transit. Those are timing differences: the books recorded the transaction, but the bank had not processed it by the statement date.
An actual discrepancy may arise from:
The response depends on the cause. Timing items are documented and carried forward. Book errors are corrected.
Begin with the last period known to be correct. Confirm the statement, ending date, and ending balance used. Then:
Do not assume the newest transaction caused the problem. A current-period alert may reflect an edit to a much older reconciled item.
The consulting business completed June with a zero difference. In August, the beginning balance is $450 lower than expected.
The audit history shows that the June $450 equipment payment was moved from Checking to a different bank account during cleanup. The expense or asset side of the original entry still exists, but the cash side no longer appears in the reconciled checking ledger.
The appropriate fix is based on what actually happened:
Entering a new $450 "reconciliation expense" may make the screen agree, but it would duplicate the economic effect and could distort taxable profit.
A reconciliation adjustment is not automatically wrong. A small historical difference may sometimes require a documented correction when source records cannot be recovered and professional judgment supports the treatment.
The risk is using an adjustment before investigating. A plug can hide omitted revenue, duplicate expenses, personal purchases, payroll errors, loan balances, or unauthorized transactions. It can also create an artificial deduction or income amount.
Materiality, age, available evidence, entity type, tax impact, and financial-statement purpose all matter. When the cause remains unknown, document the limitation and obtain qualified review.
During an active reconciliation, the software may display a "difference" equal to statement balance minus selected cleared activity. That number changes as transactions are matched and should reach zero when the period is complete.
A "reconciliation discrepancy" often refers to a problem carried into the process or created after an earlier reconciliation. Software uses the labels differently, so focus on the facts: which balance changed, when, and why?
Neither the IRS nor California FTB treats "reconciliation discrepancy" as a general deductible category. Tax returns must be supported by records that clearly show income and expenses. If resolving a discrepancy uncovers omitted income, duplicate expense, personal activity, fixed assets, payroll, or an incorrect liability, the tax treatment follows the underlying transaction.
Corrections affecting a previously filed year may require a tax-return review. Not every book correction changes tax; some move amounts between balance-sheet accounts or correct timing without changing taxable income.
Retain the original statement, prior reconciliation, audit history, correction entry, and supporting documents. California FTB guidance emphasizes records that document transactions and support filed returns.

Can I delete a reconciliation discrepancy?
Do not delete the signal without resolving the underlying entries. Trace the difference, correct the records, and preserve the audit trail.
Why did a discrepancy appear after I reconciled?
A previously reconciled transaction may have been edited, deleted, moved, or had its cleared status changed.
Can I use a reconciliation adjustment?
Only after reasonable investigation and with documentation. An unexplained adjustment can conceal a larger accounting or tax problem.
Does every discrepancy change taxable income?
No. The effect depends on the underlying transaction. Some corrections affect cash and another balance-sheet account without changing profit.
