Comparing Bank Statement and Cash Book

For any business, keeping the numbers straight is non-negotiable. And one of the most basic—but absolutely essential—tasks in accounting is comparing the bank statement with the cash book. These two records should ideally match, but in reality, they often don’t. Checking them against each other, a process known as bank reconciliation, is crucial. It helps catch errors, spot fraud, and make sure you know exactly how much cash you actually have.

In this blog, we’ll break down why comparing the bank statement and cash book is so important, where the differences come from, and the steps you need to take to reconcile them accurately.

Why Bother Comparing the Bank Statement and Cash Book?

The first instinct that came to our mind was that bank statements and cash books will always match. That can occur because you know that the same money is getting tracked. However, when the real situation involves a constant stream of pop-ups, these discrepancies may not always be the result of malpractice. Instead, they may occur due to timing issues, unexpected bank fees, or unrecorded transactions.

Here’s why you need to reconcile them regularly:

Keeps Your Cash Position Accurate: In the absence of a reconciliation, you may find yourself with more cash than you actually possess. This can lead to numerous complications, particularly when you need to cover urgent expenses but lack the necessary cash.

Catches Mistakes and Fraud: Mistakes can occur for various reasons, i.e., forgetting to record a transaction, mistyping any number, or any unauthorized transactions get unnoticed. Reconciliation can find these mistakes before they create bigger problems.

Ensures Compliance: Accuracy in records is required for legal compliance. Regular reconciliation ensures that the books are neat, accurate, and audit and tax filing ready.

Bank Statement vs. Cash Book: What’s the Difference?

Before you start comparing, make sure you understand what each record represents:

Bank Statement: This is the document that you receive from the bank. All deposits, withdrawals, and bank fees are listed. In essence, it’s what the bank considers occurred with your account during the previous month.

Cash Book: This is your record. The cash book keeps track of all cash-related transactions—receipts, payments, bank deposits, and withdrawals. This is what your business thinks it has in cash.

Why Don’t These Two Always Match?

There are plenty of reasons why your bank statement and cash book might not line up.

Unpresented Cheques (Outstanding Cheques): You may occasionally write a check to a merchant, but they may not pay it right away. Thus, although it appears in your bank as accessible cash, it is noted in your cash book as money spent.

Deposits in Transit: You deposit money at the end of the month, and it’s in your cash book. But it hasn’t cleared the bank yet, so it’s not showing up on the bank statement. These are called deposits in transit.

Bank Fees and Charges: Banks like to sneak in charges—service fees, transaction fees, or processing fees. These charges come straight out of your bank account, but they might not get recorded in your cash book until you see the bank statement.

Interest Income: Sometimes, banks pay interest on your account balance. But if you don’t record that interest in your cash book, it creates a discrepancy.

NSF (Non-Sufficient Funds) Cheques: When a cheque you deposited bounces, it’s marked as NSF. It’ll show as a deduction on your bank statement, but unless you record it in the cash book, the balances won’t match.

Errors: Mistakes are common—wrong amounts, duplicate entries, or numbers swapped around. Even a small error can throw off the balance between the bank statement and the cash book.

Steps to Reconcile Your Bank Statement with Cash Book

Reconciliation might seem tedious, but it’s straightforward once you get the hang of it. Here’s how to do it step-by-step:

Check Opening Balances

Start by making sure the opening balances on both the bank statement and the cash book match. If they don’t, check last month’s reconciliation to see if there were any errors that carried over.

Identify Unrecorded Transactions

Look through the bank statement for any transactions that didn’t make it into the cash book. Common ones include bank fees, interest income, or automatic payments (like loan installments). Record these in your cash book as adjusting entries.

Mark Outstanding Cheques and Deposits in Transit

Find any cheques you issued that haven’t been cashed yet and any deposits you recorded that haven’t cleared the bank. List these out separately, as they’ll explain some of the differences.

Correct Errors

Look for errors on both sides. Maybe you entered a deposit amount wrong, or there’s a duplicate entry in the cash book. Fix these as you go along.

Prepare Adjusting Entries

Any unrecorded items from the bank statement—fees, interest, NSF cheques—should now be recorded in the cash book. This brings your cash book closer to matching the bank’s record.

Update the Reconciliation Statement

After making all adjustments, update the reconciliation statement. This document should explain any remaining differences, such as outstanding cheques or deposits in transit, and show that the adjusted cash book balance now matches the bank statement.

Final Review

Check your work. Make sure every discrepancy is accounted for, and confirm that the final balances align. Save the reconciliation as part of your records.
