Balance sheet reconciliation is the process of checking every account on your balance sheet against its supporting records — bank statements, invoices, loan documents — to confirm the numbers are accurate. When accounts aren't reconciled, BAS lodgements can be wrong and EOFY becomes a scramble of corrections.
For Australian businesses lodging BAS quarterly and closing books at 30 June, reconciliation is how you catch errors before they reach the ATO or your accountant's desk. Research from Dext's 'Built for Bigger Things' report (2025) found that 21% of SMB owners spend 21 to 40 hours per month on financial admin. Reconciliation done regularly reduces that rework rather than adding to it.
This guide covers which accounts to check, how to reconcile them step by step, the mistakes that throw most balance sheets out, and how to build a monthly routine that keeps your books clean.
Key takeaways
Balance sheet reconciliation verifies every account balance against external or internal records – it's broader than bank reconciliation alone.
Unreconciled accounts can lead to BAS errors, EOFY delays, and extra clean-up work at tax time.
The accounts that need reconciliation most often: bank, accounts receivable, accounts payable, GST clearing, and loan accounts.
Monthly reconciliation catches errors when they're small – annual reconciliation compounds them.
Connected accounting software can reduce manual matching time and support faster, more accurate reconciliation.
What is balance sheet reconciliation?
The process covers every account on your balance sheet – not just your bank. Your general ledger accumulates transactions over time, and errors, duplicates, and missed entries can compound if no one catches them.
Balance sheet reconciliation vs. bank reconciliation
Bank reconciliation is one type of balance sheet reconciliation. It checks your bank account in the general ledger against your bank statement. Balance sheet reconciliation goes further – it covers receivables, payables, GST clearing accounts, loans, and equity. If you're only doing bank reconciliation, you're checking one piece of a larger picture.
The distinction matters because a business can have a perfectly reconciled bank account and still carry errors in accounts receivable, GST clearing, or payroll liabilities – accounts that directly affect your BAS and EOFY reporting.
Why balance sheet reconciliation matters for Australian businesses
Reconciliation confirms your books reflect what actually happened, and the consequences of skipping it show up at the worst times – incorrect BAS lodgements, surprise costs at tax time, or a loan application that stalls because the numbers don't add up.
BAS confidence
Your BAS draws on your books. If accounts receivable, GST clearing, or bank accounts are wrong, your BAS may be too. Reconciling before each quarterly lodgement helps catch discrepancies early, before they flow through to your activity statement.
EOFY preparation
Reconciled books let you close year-end quickly. Unreconciled accounts can lead to extra time and cost at tax time when your accountant or bookkeeper has to trace and fix errors that accumulated over the year.
Cash flow visibility
You can't make confident decisions about spending or investment if your balance sheet doesn't reflect reality. According to RBA and ScaleSuite data (2025), the median Australian SMB holds roughly three months of cash reserves. When margins are that thin, the difference between actual and recorded cash matters.
Loan and finance readiness
Lenders and brokers review balance sheets. Reconciled accounts signal financial credibility. If you're applying for a loan or line of credit, an unreconciled balance sheet raises questions.
With BAS due quarterly, reconciling before each lodgement is the most practical way to catch discrepancies before they reach the ATO.
Which balance sheet accounts need reconciliation?
Not every account carries the same risk. Here's what to check and how often.
Account type | Supporting record | Frequency | What to check |
Bank accounts | Bank statement | Monthly | GL balance matches bank statement balance. Investigate outstanding cheques, deposits in transit, and unallocated bank feed transactions. |
AR aging report / sub-ledger | Monthly | Invoices marked as paid match payments received. No aged invoices that should have been written off or followed up. | |
AP aging report / sub-ledger | Monthly | Bills entered match supplier statements. No duplicate bills or payments recorded without a matching bill. | |
GST clearing account | BAS lodgement records | Quarterly (before BAS) | GST collected minus GST paid nets to your BAS liability. Miscoded GST categories are a frequent source of discrepancies. |
Loan and credit card accounts | Lender statements | Monthly | Balance matches lender statement. Interest accruals and repayment allocations are correct. |
Payroll liabilities | Pay run reports | Each pay cycle | Super, PAYG withholding, and leave provisions in the GL agree with your pay run summaries. |
Where to start: bank accounts are the most straightforward. Most businesses already do some form of account reconciliation, and accounting software with bank feeds can reduce the manual matching involved. Once your bank accounts are clean, work outward to receivables, payables, and then GST and payroll.
How to reconcile your balance sheet step by step
1. Pull your balance sheet report
Run a balance sheet report as at the reconciliation date – typically the last day of the month. Use a specific date, not "today." In MYOB Business, you can generate this via Reports > Balance Sheet.
2. Gather supporting documents
Collect the records you'll compare against: bank statements, AR and AP aging reports, loan statements, BAS records, and pay run summaries. One document per account.
3. Compare each account balance
Work through the balance sheet top to bottom – assets first, then liabilities, then equity. For each account, compare the general ledger balance to the supporting document. Note any differences.
4. Identify and investigate discrepancies
Common causes of discrepancies include:
Timing differences: a cheque you've recorded hasn't cleared the bank yet, or a payment was received after the statement date.
Data entry errors: a transposed number, an amount entered in the wrong account, or a transaction recorded twice.
Unallocated bank feed transactions: imported from the bank but sitting in a clearing account, not coded to the right place.
Missing adjusting entries: depreciation, accruals, or prepayments that haven't been posted.
Start with the largest discrepancy and work down. Small timing differences often resolve themselves in the next period. Larger gaps usually point to a specific transaction that needs correcting.
5. Make corrections
Post journal entries to fix errors. Reverse duplicate transactions. Allocate unmatched bank feed items. For complex adjustments — depreciation schedules, accruals, intercompany entries — consult your bookkeeper or accountant.
6. Document and sign off
Record what was checked, what was adjusted, and the final confirmed balance. Even a simple note — "Bank account reconciled to 30 April statement, $0 variance, reviewed by [name]" — creates accountability and an audit trail. A trial balance report can also help confirm your books are in order after corrections.
Common mistakes that throw your balance sheet out
A quick clarification – when people say "my balance sheet doesn't balance," they can mean two things. First, the balance sheet report itself is out of balance — assets don't equal liabilities plus equity — which usually signals a system or data entry issue.
The more common scenario is that individual account balances don't reconcile to their supporting records – your bank GL doesn't match your bank statement, or your GST clearing account doesn't agree with your BAS. This section focuses on that second scenario.
Unallocated bank feed transactions
Transactions imported from the bank but left sitting in a clearing account. They show up on your bank statement but aren't coded to the right account in your books. This is a frequent cause of discrepancies – and straightforward to fix.
Reconciling to the wrong date
Your balance sheet is dated 30 June, but the bank statement you're comparing against runs to 1 July. Even one day's difference can introduce mismatches.
Duplicate transactions
A payment entered manually and also imported through a bank feed. Bank feed auto-matching in MYOB Business can help reduce this risk by removing the need for manual data entry on imported transactions.
Missing adjusting entries
Depreciation, accruals, and prepayments that haven't been posted at period end. These affect your balance sheet balances but are easy to overlook if they're not part of your monthly routine.
GST miscoding
Transactions recorded with the wrong GST category — GST-free coded as GST-inclusive, or vice versa — throw your GST clearing account out and can affect your BAS.
Editing reconciled transactions
Changing a transaction after it's been reconciled breaks the previous reconciliation. If a correction is needed, post a new adjusting entry rather than editing the original.
Balance sheet reconciliation best practices
Reconcile monthly, not annually
Monthly catches errors when they're one transaction, not twelve months of compounding issues. If EOFY is your first reconciliation of the year, the clean-up will take significantly longer. Decision trigger: if you only reconcile at year-end, consider starting a monthly rhythm before next quarter's BAS.
Work in order of verifiability
If an upstream account has errors — say, unallocated bank feed transactions — those errors cascade into your GST clearing and payroll liability reconciliations. Fix the accounts with clear external documents first (bank statements, lender statements), then move to accounts that rely on internal sub-ledgers (AR, AP, GST).
Use a checklist
A simple list of accounts to check each month prevents things from being missed. The account-type table earlier in this article works as a starting point.
Don't skip the sign-off
Even an informal "checked by [name], [date]" creates accountability and an audit trail. If your bookkeeper or accountant reviews your books, a signed-off reconciliation can save them time, which may reduce back-and-forth and clean-up costs.
Connect your bank feeds
Automatic transaction import removes a common source of reconciliation problems – manual data entry errors. More than 250,000 businesses across Australia and New Zealand use MYOB's automatic transaction matching to reduce the time and effort involved in bank reconciliation.
When it's time to use accounting software for reconciliation
If any of these sound familiar, it may be time to consider software that supports reconciliation:
You're spending more than an hour per month on manual transaction matching.
You manage three or more bank or credit card accounts.
You've made a BAS error that traced back to an unreconciled account.
Your bookkeeper or accountant keeps finding errors you missed.
What to look for: automatic bank feed import, transaction matching rules, balance sheet reporting, GST tracking, and multi-account reconciliation.
Connected accounting software doesn't fully automate reconciliation – you still review and confirm matches. It imports transactions directly from your bank and suggests matches based on amount, date, and description – flagging discrepancies so you can resolve them faster.
MYOB Business connects to more than 130 banks across Australia and New Zealand, importing transactions automatically. Smart Reconciliation in MYOB Business Pro is designed to support faster matching across multiple bank and credit card accounts – learning how your business categorises transactions to suggest matches. MYOB Business also supports BAS preparation by helping pre-fill activity statement data from your reconciled accounts.
As Greenspace Bookkeeping put it: "Using the MYOB suite of products really helps with making sure that the client's data is accurate ... it allows us to reconcile the accounts back to the data on a timely basis."
MYOB customers save an average of more than 8 hours of admin every week.
What to do next
If you haven't reconciled recently: start with your bank accounts this month. Pull a balance sheet report, compare it to your bank statement, and note any discrepancies.
If you reconcile but not regularly: set a monthly calendar reminder. Even reconciling two or three accounts consistently each month is more useful than a once-a-year sweep across all of them.
If you want to reduce manual work: try connecting your bank feeds in MYOB Business. Automatic transaction import can significantly reduce the time you spend on reconciliation.
If you need help: bring your reconciliation notes to your next adviser meeting. Pre-reconciled accounts mean less back-and-forth and a faster turnaround on your tax work. CPA Australia's small business resources are also a good starting point if you want to learn more about managing your finances independently.
Frequently asked questions
How often should each account be reconciled?
Bank accounts: monthly at minimum. Accounts receivable and accounts payable: monthly. GST clearing: quarterly, before each BAS lodgement. Payroll liabilities: each pay cycle. Loan accounts: monthly, matched to lender statements.
What if I've fallen behind on reconciliation and EOFY is close?
Start with bank accounts – they're the fastest to verify and have the clearest supporting documents. Prioritise any account that feeds directly into your BAS (GST clearing, accounts receivable).
If the gap is more than a few months, consider bringing your bookkeeper or accountant in early rather than attempting a full-year reconciliation under time pressure. Prioritising the highest risk accounts is better than doing nothing, especially if you also flag what still needs review.
Where should I start when a discrepancy is hard to trace?
Check the date range first: confirm the balance sheet report and the supporting document cover exactly the same period. Then look for unallocated bank feed transactions, which are the easiest to miss. If neither resolves it, run a transaction detail report for the account and compare line by line. Start with the largest variance.
Who should do balance sheet reconciliation – me or my accountant?
Monthly bank, AR, and AP reconciliation is manageable for most small business owners who handle their own books. Leave complex adjustments — depreciation, accruals, intercompany transactions — to your accountant or bookkeeper. When you hand over accounts that are already reconciled, your adviser spends their time on higher-value work (tax planning, cash flow strategy) rather than tracing data entry errors – which can mean a lower bill and a faster turnaround.
Build the habit, not the backlog
Reconcile monthly and you're more likely to catch BAS issues before they become bigger clean up jobs – because errors caught at one transaction are far cheaper to fix than errors discovered across a full financial year. The point of reconciliation isn't perfection – it's confidence that your numbers hold up when it matters, whether that's BAS lodgement or a lender asking to see your books.
If you take one thing from this guide, make it this: set a monthly reminder, start with your bank accounts, and work through the checklist above. By the time EOFY arrives, your books will already be in order – and your accountant will thank you for it.
