Your bank reconciliation comes out to zero. Good news.
Probably.
A balanced reconciliation tells you that the difference between your accounting records and your bank records has been accounted for. That's important. But it doesn't necessarily tell you that every item used to explain that difference is correct, current, or resolved. An outstanding check that's been sitting there for six months can still be a reconciling item. So can a deposit that should have cleared long ago. A manual adjustment can make the numbers work without fixing the transaction that caused the problem.
For a growing company, that's the difference between completing a bank reconciliation and learning something from it.
Bank reconciliation is the process of comparing the cash activity recorded in your accounting system with the activity reported by your bank. The goal is to identify and explain differences between the two records.
Those differences are normal. Your accounting system and bank don't necessarily record the same transaction at the same time. A check may have been recorded in your books but not yet deposited by the recipient, while a bank fee may appear on the statement before anyone records it in the general ledger.
Reconciliation identifies those differences and determines what needs to happen next. Some items require an accounting entry. Others are legitimate timing differences that simply need to be documented and monitored. Still others require investigation because neither explanation is immediately obvious.
A bank reconciliation statement documents the differences between the cash balance in your accounting records and the corresponding balance reported by the bank. Traditionally, the reconciliation begins with the two balances and accounts for items such as:
Modern accounting platforms can automate much of the matching process, particularly when bank feeds are connected directly to the general ledger. That makes reconciliation faster, but it doesn't eliminate the need to understand the exceptions. That's where much of the accounting work lives.
Suppose your accounting system shows $102,400 in a checking account at month-end, while the bank statement shows $98,750. You have a $3,650 difference.
At first glance, something appears to be wrong. Then you investigate.
| Item | Effect |
|---|---|
| Book balance | $102,400 |
| Bank fee not recorded in books | -$300 |
| Interest income not recorded in books | +$50 |
| Adjusted book balance | $102,150 |
| Outstanding payment not yet cleared by bank | $3,400 |
| Bank balance | $98,750 |
| Bank balance + outstanding payment | $102,150 |
The $300 bank fee and $50 of interest require entries in the accounting system because the bank has recorded activity the books haven't. The $3,400 outstanding payment is different: it has already been recorded in the books, but the recipient hasn't deposited or cleared the payment yet.
Once those items are accounted for, the reconciliation balances. But the $3,400 payment deserves another question: How long has it been outstanding? Three days may be perfectly ordinary; three months may deserve investigation.
The reconciliation reaches the same zero either way. What that zero tells you depends on what's behind it.
The mechanics can vary by accounting system, but the basic process is straightforward. The IRS's recordkeeping guidance specifically recommends reconciling checking accounts and illustrates the process using outstanding checks, deposits not yet credited, bank charges, and recording errors.
Confirm that the beginning balance in the accounting records agrees with the prior reconciliation. If it doesn't, investigate before proceeding. Beginning with an unexplained difference makes the rest of the reconciliation considerably less useful.
Compare deposits recorded in the accounting system with deposits appearing on the bank statement. Identify any deposits that have been recorded in the books but haven't yet reached the bank; these may be legitimate deposits in transit, particularly around month-end.
Compare checks, ACH payments, card transactions, transfers, and other withdrawals. Payments recorded in the books but not yet processed by the bank may be legitimate outstanding items, but how long they've been outstanding matters.
Look for activity the bank knows about before the accounting system does. Common examples include:
Legitimate items should be recorded in the accounting system using the appropriate accounts.
A transaction appearing on one side without an obvious counterpart shouldn't automatically become a miscellaneous adjustment. Determine what happened. The answer could be a duplicate transaction, incorrect amount, posting error, timing difference, unauthorized payment, or something else entirely.
Correct the accounting records for items that genuinely require entries. Adjustments should have a clear reason and appropriate support rather than simply providing a convenient way to eliminate a difference.
Once the numbers agree, look at what's left on the reconciliation. Consider how old the outstanding items are, whether the same differences appeared in prior months, and whether anything still requires follow-up.
This review matters because a reconciliation can be mathematically complete while some of the underlying work remains unfinished.
A difference between the bank and general ledger isn't inherently evidence of an accounting problem. Many differences result from timing, while others identify transactions that need to be added, corrected, or investigated.
A payment can be recorded in the books immediately but take days or weeks to clear the bank. Until it does, the book balance and bank balance will differ.
A company may record a customer payment or deposit before the bank processes it. This is particularly common around the end of a reporting period.
Banks can post charges or interest directly to an account. Those transactions may not reach the accounting system until the statement or bank feed is reviewed.
A customer payment that was initially recorded as received may later be rejected or reversed. The accounting records need to reflect the reversal.
Amounts can be entered incorrectly, transactions can be duplicated, or activity can be posted to the wrong bank account. Reconciliation is often where those mistakes surface.
Occasionally, the problem is a transaction nobody recognizes. That deserves prompt investigation. Reconciliation is one of the mechanisms that can expose unauthorized or unexpected cash activity before it disappears into months of subsequent transactions.
Bank reconciliation provides an independent comparison between what the company believes happened to its cash and what its financial institution recorded. That makes it useful for finding:
This is one reason reconciliation belongs within a broader system of accounting controls. The IRS notes that bank records are third-party source documents that can provide an audit trail and help determine whether bank-account transactions are being properly recorded.
A reconciliation is therefore more than clerical cleanup at the end of the month. It's one of the recurring opportunities to test whether the cash reported in the books can be supported by independent records.
Here's where the zero at the bottom of the reconciliation can become misleading. Suppose every difference between the bank and books has been categorized and the reconciliation balances perfectly. The next step is to look at what's actually on it.
An outstanding check is a perfectly legitimate reconciling item—for a while. If the same check remains outstanding month after month, the relevant question becomes why it hasn't cleared.
The payment may have been lost, voided, replaced, recorded incorrectly, or never received. Carrying it indefinitely preserves the mathematical reconciliation while leaving the underlying issue unresolved.
Deposits in transit should generally clear quickly. If one persists across multiple reconciliations, it may no longer be reasonable to treat it as an ordinary timing difference. The accounting team needs to determine what happened to it.
Occasional adjustments are normal. Recurring adjustments for the same issue can indicate a broken process upstream. A system may not be integrated correctly, transactions may be mapped incorrectly, or a payment processor may not reconcile cleanly to the general ledger.
Correcting the result every month can allow the underlying process problem to continue indefinitely.
Giving a difference a label doesn't explain it. An “other reconciling item” may make a spreadsheet balance, but material or unusual differences should have support showing what they represent and why their treatment is appropriate.
One of the most useful things to examine is the reconciliation history. Which items were present last month? Were they there the month before that?
A reconciliation populated with aging items can indicate that the company is documenting problems faster than it is resolving them. The account can balance perfectly while the process behind it remains weak.
For many businesses, bank accounts should be reconciled at least monthly as part of the month-end close. IRS Publication 583 specifically recommends reconciling a checking account each month.
Higher-volume or higher-risk accounts may warrant more frequent reconciliation. Weekly or even daily review can make sense when an account:
Frequency should reflect the amount of activity and the consequences of allowing an error to remain undetected. A low-volume account with predictable activity presents a different risk from an operating account processing hundreds or thousands of transactions.
Whatever cadence the company chooses, consistency matters. A reconciliation performed irregularly becomes harder because each missed period adds transactions and makes discrepancies more difficult to trace.
A small company may have one operating account and a relatively short bank statement. As the business grows, it may add:
The reconciliation process has to grow with that environment. At sufficient scale, manually checking transactions against a statement becomes impractical. Accounting systems and bank feeds can automate much of the matching, while the accounting team concentrates on exceptions, review, and resolution.
Process ownership becomes more important too. A growing company needs to know who prepares the reconciliation, who reviews it, who investigates old outstanding items, who can record adjustments, and who confirms that unusual differences have actually been resolved.
Those responsibilities are part of building an accounting operation that can continue producing reliable financials as the company becomes more complicated. For a broader look at how those requirements evolve, our guide to small business accounting services examines how the accounting function changes as a company grows.
A completed bank reconciliation should leave you able to explain the relationship between the balance in your books and the balance at the bank. Sometimes that explanation is simple: a payment hasn't cleared yet, a deposit was made at month-end, or a bank fee needed to be recorded.
Other times, the reconciliation exposes something worth investigating. The same item has been outstanding for months. An adjustment keeps returning. A deposit never arrived. A transaction doesn't belong there. That's where reconciliation becomes particularly valuable.
The goal isn't merely to make two numbers agree. It's to understand the differences well enough to know that they should agree.

A zero at the bottom of a reconciliation is useful. Knowing how you got there is considerably more useful.
Bank reconciliation is the process of comparing the cash transactions and balance recorded in a company's accounting system with the corresponding bank statement. Differences are identified, investigated, and either adjusted in the books or documented as legitimate timing differences.
Bank reconciliation helps verify cash balances and can identify missing transactions, duplicate entries, recording errors, bank fees, returned payments, unusual withdrawals, and unresolved timing differences. Regular reconciliation also supports a stronger month-end close and financial reporting process.
A bank reconciliation statement documents the differences between the cash balance shown in a company's accounting records and the balance reported by its bank. It identifies items such as outstanding payments, deposits in transit, bank fees, interest, and other differences needed to explain or reconcile the two balances.
Many businesses reconcile bank accounts monthly as part of the month-end close. Accounts with high transaction volume, significant cash activity, or greater risk may benefit from weekly or even daily reconciliation or review.
Bank reconciliation compares a cash account in the general ledger with records from the corresponding financial institution. Balance sheet reconciliation is broader: it substantiates balances in other balance sheet accounts using appropriate supporting records. Bank reconciliation is therefore one specific type of balance sheet reconciliation.
