Definition of Bank Statement Reconciliation

Bank statement reconciliation, commonly called bank reconciliation, is the process of comparing transactions and balances recorded in a company's accounting records with information reported by its bank.

The purpose is to identify and explain differences so that the company's accounting records accurately reflect its cash transactions and balance.

Differences can arise from:

• Timing differences
• Outstanding checks
• Deposits in transit
• Bank fees
• Interest
• Returned payments
• Electronic transactions
• Recording errors
• Unauthorized or unfamiliar transactions

For example, a Florida business may record a $1,200 check when it is issued. If the recipient has not deposited the check by month-end, the payment will appear in the company's accounting records but may not yet appear as a cleared transaction on the bank statement.

Therefore, you must consider the outstanding check when reconciling the two balances.

Purpose of Bank Reconciliation in U.S. Business Operations

Regular bank reconciliation can serve several important purposes:

1. Detects Errors and Omissions – Helps identify missing, duplicated, or incorrectly recorded transactions.
2. Identifies Unusual Transactions – Regular review can help businesses notice unauthorized or unfamiliar activity.
3. Improves Cash Accuracy – Helps ensure the cash balance in the accounting system reflects transactions that should have been recorded.
4. Supports Financial Reporting – Accurate cash records contribute to reliable balance sheets and cash flow information.
5. Supports Tax Recordkeeping – Reconciled records can help businesses maintain documentation supporting income and expenses reported on federal tax returns.
6. Improves Financial Management – Reliable cash information supports budgeting, forecasting, and payment decisions.
7. Strengthens Internal Controls – Regular reconciliation can help identify errors and control problems before they accumulate.

A bank reconciliation does not guarantee that fraud or accounting errors will be detected, but it can be an important component of a company's internal control and recordkeeping processes.

Common Items That Cause Reconciliation Differences

Outstanding Checks

Outstanding checks are checks that a business has issued and recorded in its books but that have not yet cleared the bank.

For example, a company issues and records a $2,000 vendor check on March 29. If the vendor deposits it in April, the March bank statement may not include the transaction even though the company's books do.

Deposits in Transit

Deposits in transit are amounts the business records as deposits but that have not yet appeared on the bank statement as of the reconciliation date.

For example, a business deposits $5,000 late on the final day of the month. The business may have recorded the deposit immediately, while the bank may process it during the following month.

Bank Fees

Service charges, wire fees, account fees, and other bank charges may appear on the bank statement before the company records them in its accounting system.

These amounts generally require an adjustment to the company's books.

Interest Income

A bank may credit interest to an account during the period. If the business has not yet recorded the interest, it may need to make an accounting entry.

Errors

Errors can occur in either the company's records or, less commonly, the bank's records.

Examples include:

• Incorrect transaction amounts
• Duplicate entries
• Missing transactions
• Incorrect account classifications
• Data-entry errors

Investigate differences rather than automatically adjusting them without supporting information.

Returned or NSF Payments

A customer's payment may initially be recorded as received but later be returned because of insufficient funds or another problem.

When this occurs, the business generally needs to reverse or otherwise adjust the previously recorded receipt and, when appropriate, restore the applicable customer receivable.

Electronic Transactions

ACH payments, debit card transactions, automatic withdrawals, merchant deposits, and electronic transfers may appear on a bank statement before you enter them into the accounting system.

Regular reconciliation helps identify these transactions.

Steps in Bank Statement Reconciliation

1. Obtain the Bank Statement

Collect the bank statement for the period being reconciled.

Businesses using online banking may obtain statements electronically rather than waiting for paper copies.

2. Compare Deposits and Receipts

Compare deposits appearing on the bank statement with receipts recorded in the company's accounting records.

Identify deposits in transit and investigate unexplained differences.

3. Compare Payments and Withdrawals

Match checks, ACH payments, transfers, debit transactions, and other withdrawals with the company's books.

Identify outstanding checks and investigate unfamiliar transactions.

4. Identify Bank-Only Transactions

Look for items that the bank has recorded, but the business has not yet entered into its accounting system.

Examples include:

• Bank service charges
• Interest
• Automatic payments
• Returned checks
• Electronic transfers

5. Record Necessary Book Adjustments

Update the accounting records for legitimate transactions that were missing or incorrectly recorded.

For example, if the bank statement contains a $50 service charge that has not been recorded, the company might make a simplified entry such as:

Timing differences such as outstanding checks and deposits in transit generally do not require new journal entries when the company has already recorded them.

6. Calculate the Adjusted Bank Balance

A simplified reconciliation may use:

Any identified bank errors would also be considered where applicable.

7. Confirm the Reconciled Balances Agree

After valid book adjustments and reconciliation items are accounted for:

If the balances still differ, the business should investigate the remaining discrepancy rather than forcing the reconciliation to balance.

Bank Balance vs. Book Balance

The two balances do not have to be identical before reconciliation. Legitimate timing differences frequently explain why they differ.

Bank Reconciliation vs. Cash Account Reconciliation

Bank reconciliation compares a company's accounting records with information from its financial institution.

Cash account reconciliation can be broader and may involve verifying multiple cash-related sources and accounts.

A business with several bank accounts generally reconciles each applicable account separately.

How Bank Reconciliation Supports Internal Controls

Bank reconciliation can be an important internal control over cash.

For stronger controls, businesses may consider separating responsibilities among employees where practical.

For example, the employee who authorizes payments or handles cash may be different from the person who reviews the bank reconciliation.

Independent review makes it harder for an unauthorized transaction or accounting error to go unnoticed.

For very small businesses where full segregation of duties is impractical, an owner or manager can periodically review bank statements and completed reconciliations.

Bank Reconciliation and IRS Recordkeeping

The IRS does not impose a general rule requiring every business to prepare a formal bank reconciliation on a particular schedule.

However, U.S. businesses must maintain records that adequately support information reported on their federal tax returns.

The IRS explains that business records should support:

• Gross income
• Deductions
• Credits
• Business expenses
• Other amounts reported on tax returns

Bank statements, deposit records, canceled checks, electronic payment information, invoices, receipts, and accounting records can all form part of a business's supporting documentation.

Regular bank reconciliation helps ensure transactions reflected in bank records are captured in the company's accounting system.

Advantages and Limitations of Bank Reconciliation

Advantages

Interesting Fact

Did you know? The IRS specifically recommends reconciling a business checking account each month. IRS Publication 583 explains that reconciliation helps verify the account balance, identify bank charges, and correct errors in bank statements, checkbooks, and accounting records.

Statistic

According to the U.S. Taxpayer Advocate Service, about 57 million small businesses and self-employed taxpayers operate in the United States. Maintaining accurate business records — including records supporting bank transactions — is an important part of meeting federal filing and recordkeeping responsibilities.

Frequently Asked Questions (FAQ)

1. What is the main goal of bank statement reconciliation?

The primary goal is to explain differences between the bank's records and the company's accounting records and ensure that legitimate transactions are properly reflected in the books.

The objective is not simply to make the unadjusted bank statement balance equal the original book balance.

2. How often should bank reconciliation be performed?

The IRS recommends reconciling a business checking account each month. Businesses with high transaction volumes, significant cash activity, or greater control risks may reconcile more frequently, such as weekly or even daily.

3. What tools can businesses use for bank reconciliation?

Businesses can use accounting platforms such as QuickBooks, Xero, or Sage; enterprise accounting systems; specialized reconciliation software; or spreadsheets.

Many accounting systems can import bank transactions and automatically suggest matches, although businesses should still investigate discrepancies and review the completed reconciliation.

4. What if the balances do not match after reconciliation?

The business should investigate unresolved differences. Potential causes include missing transactions, duplicate entries, incorrect amounts, outstanding checks, deposits in transit, bank fees, returned payments, bank errors, or transactions recorded in the wrong accounting period.

Journal entries should be made only when the company's accounting records require adjustment. Legitimate timing differences generally do not require duplicate entries.

5. Is bank reconciliation required by law in the United States?

There is no general federal tax rule requiring every U.S. business to prepare a formal bank reconciliation each month. However, businesses must maintain adequate records to support amounts reported on their federal tax returns. The IRS specifically recommends monthly reconciliation of a business checking account as a good recordkeeping practice.
