How often should I reconcile my business bank account?

At least once a month, right after your bank statement closes. Monthly reconciliation keeps errors small and easy to trace. Businesses with high transaction volumes sometimes reconcile weekly to stay on top of cash flow.

What's the difference between my book balance and my bank balance?

Your book balance is what your accounting records say; your bank balance is what the bank reports. They differ because of timing — uncleared cheques, deposits in transit — and because of items only one side has recorded yet, such as bank fees. Reconciliation identifies and explains every one of those differences.

What if my account won't balance no matter what?

Work through the usual causes in order: transposed digits, duplicate or missing entries, unrecorded fees, wrong dates, and an incorrect opening balance. Check whether the difference divides evenly by nine, which points to a transposition. Never invent an entry to force a match — find the real cause or ask your bookkeeper.

Does reconciliation affect my tax return?

Yes — filing on unreconciled books risks over- or under-stating income and expenses, which affects the tax you owe. Reconcile before you prepare any return so the figures are accurate. This is general information; confirm current rules with the relevant country's tax authority or a qualified local tax professional.

Can software do the reconciliation for me?

It can do most of it. Tools like Tallium import your bank transactions, suggest matches against your existing records, and flag anything unexplained, so your job becomes reviewing and approving rather than matching by hand. You still make the final judgement on unusual items.

Do I need to reconcile accounts other than my main bank account?

Yes. Reconcile every account the business uses, including credit cards, savings accounts and payment processors like your card terminal or online gateway. Each one can hold errors or charges you haven't recorded, and together they give you a complete, trustworthy picture of your cash.

How to Reconcile Your Business Bank Account

Bank reconciliation is the monthly check that makes sure your accounting records match what actually happened in your bank account. This guide walks you through it step by step and shows how to keep it painless.

The short answer

Reconciling means matching every transaction in your books to your bank statement so the two balances agree.
Do it monthly, right after your statement closes, before you run reports or file tax.
Match deposits and payments line by line, then investigate anything left over.
Common gaps: bank fees, uncleared cheques, duplicate entries, and timing differences.
Software that imports your bank feed and auto-suggests matches turns an afternoon into a few minutes.

What bank reconciliation actually means

Reconciliation is simply proving that your accounting records tell the same story as your bank. Your books say you have a certain amount of money; your bank statement says something too. Reconciling is the process of matching them transaction by transaction until they agree — and explaining any difference.

Think of it as a monthly health check. When the two match, you can trust every report you pull: your profit figure, your cash position, and the numbers you hand to your accountant or tax authority. When they don't match, reconciliation is how you find out why before it becomes a bigger problem.

Why it matters for a small business

Catch mistakes early — a mistyped amount, a payment entered twice, or a supplier charge you forgot.
Spot fraud and unauthorised charges while you can still dispute them.
Know your true cash position, not the optimistic version in your head.
File tax returns on accurate numbers — under- or over-stating income both cause trouble.
Make your year-end and any audit far faster because the books are already clean.
Sleep better: you've verified the money is really there.

Before you start: what to gather

Reconciliation goes quickly when everything is in front of you. Pick a consistent time each month — most owners do it in the first few days after the previous month closes, once the statement is final.

Your bank statement for the period (or the exported feed).
Your accounting records or ledger for the same dates.
Receipts and invoices for anything you're unsure about.
Last month's reconciliation, so you know your opening balance and any items still outstanding.

Step-by-step: reconcile in seven moves

1
Confirm your opening balance
Check that the opening balance in your books matches the closing balance from last month's reconciliation. If they don't agree, fix that first — everything downstream depends on it.
2
Bring in the bank statement
Get the full list of transactions for the period, either on paper or as an imported feed. Note the bank's closing balance — that's the number you're working toward.
3
Match deposits and income
Tick off every deposit on the statement against a matching entry in your books — customer payments, transfers, refunds. Anything on the statement but not in your books needs to be recorded.
4
Match payments and withdrawals
Do the same for money going out: supplier payments, wages, direct debits, card purchases. Match each one to a bill or expense in your records.
5
Add what only the bank knew about
Record items the bank applied but you hadn't entered — account fees, interest, standing charges. These are a common source of a small stubborn difference.
6
List uncleared items
Note anything in your books that hasn't hit the bank yet — a cheque you wrote that isn't cashed, or a deposit in transit. These are timing differences, not errors, and they explain a legitimate gap.
7
Confirm the balances agree
Take the bank's closing balance, adjust for uncleared items, and check it equals your book balance. If it matches to the cent, you're reconciled. If not, move to investigating the difference.

When it doesn't balance: where to look

A difference almost always comes from one of a few familiar culprits. Work through them in order rather than re-checking everything at random.

Transposed numbers — 54 entered as 45. If the difference divides evenly by 9, suspect this.
A transaction entered twice, or missed entirely.
Bank fees or interest you haven't recorded yet.
A payment dated in the wrong month.
An uncleared cheque or a deposit still in transit from a previous month.
The wrong opening balance carried over.

Tallium pulls in your bank transactions and suggests matches against existing records, flags anything unexplained, and remembers uncleared items from month to month so nothing slips.
