You can undo a reconciliation, but the method depends on whether it was completed recently or months ago

If you reconciled your bank account in QuickBooks Online and now need to reverse it — because you found an error, matched the wrong transactions, or need to re-do the whole thing — you have two paths. For reconciliations completed in the current or previous month, QuickBooks lets you unreconcile individual transactions or clear the entire reconciliation. For older reconciliations, you'll need to manually reverse the process by re-opening the reconciliation and unmarking transactions. The faster route is almost always to unreconcile rather than start over, because it leaves your transaction history intact.

The good news is that unreconciling does not delete anything. Your transactions stay in your register with all their details. You're straightforward removing the "reconciled" status so you can fix what went wrong and match them again correctly.

Key Takeaways

  • Recent reconciliations can be undone by going to the Reconcile page, finding the reconciliation, and clicking Unreconcile — this removes the reconciliation status from all matched transactions at once.
  • Individual transactions can be unreconciled one at a time from the bank register by unchecking the checkmark next to each transaction.
  • Reconciliations older than two months may not show an Unreconcile button, in which case you manually uncheck transactions in the bank register to reverse the match.
  • After unreconciling, your bank balance in QuickBooks will change, so verify it matches your actual bank statement before re-reconciling.
  • If you unreconcile by mistake, you can re-reconcile the same transactions — QuickBooks does not delete the history of what was matched.

How to unreconcile a recent reconciliation all at once

Open QuickBooks Online and go to the Reconcile page. You'll find this under the Accounting menu on the left sidebar, or by searching "Reconcile" in the search bar at the top. The page shows a list of all your bank accounts and their reconciliation history.

Find the reconciliation you want to undo. Each row shows the account name, the date it was reconciled, and the ending balance on that reconciliation. Click on the row for the reconciliation you want to reverse. QuickBooks will open a summary showing which transactions were matched and the reconciliation details.

Look for the Unreconcile button. It appears in the top right of the reconciliation summary, but only for reconciliations completed within the last two months or so. If you see it, click it. QuickBooks will ask you to confirm — click Unreconcile again. All transactions that were marked as reconciled will be unmarked at once, and your bank balance in QuickBooks will revert to what it was before that reconciliation.

How to unreconcile individual transactions from the bank register

If you only need to undo the reconciliation status on a few specific transactions — not the entire reconciliation — you can do this directly from your bank register. Go to the Banking menu and select the account you want to work with. QuickBooks opens the bank register for that account.

Look for the checkmark column on the left side of each transaction. A checkmark means that transaction was included in a reconciliation. Find the transaction you want to unreconcile and click the checkmark to remove it. The checkmark disappears, and that transaction is now unreconciled. Your account balance updates automatically.

You can uncheck as many transactions as you need this way. This method is useful if you reconciled correctly for most transactions but matched one or two incorrectly. It's slower than using the Unreconcile button if you need to undo dozens of transactions, but it gives you precise control over which transactions stay reconciled and which ones don't.

What to do if the Unreconcile button is not there

QuickBooks Online does not always display the Unreconcile button for older reconciliations — typically those more than two months old. If you don't see the button, you'll need to manually uncheck the transactions in your bank register instead.

Go to the Banking menu, select your account, and open the bank register. Scroll through and find all the transactions that were part of the reconciliation you want to undo. You can identify them by the checkmark in the leftmost column. Click each checkmark to remove it. This takes longer than clicking Unreconcile once, but it accomplishes the same thing: those transactions are no longer marked as reconciled.

If you have dozens of transactions to uncheck and you're not sure which ones were part of that specific reconciliation, write down the reconciliation date and ending balance from the Reconcile page. Then uncheck transactions between the previous reconciliation date and the one you're undoing. This helps you stay organized and avoid unchecking the wrong transactions.

What happens to your account balance after you unreconcile

When you unreconcile a reconciliation, your QuickBooks bank balance changes when ready. It reverts to whatever it was before that reconciliation was completed. This is correct behavior — the reconciliation is no longer in effect, so the balance should reflect that.

Before you re-reconcile or move forward, verify that your new QuickBooks balance makes sense. Pull up your actual bank statement from the date before the reconciliation you just undid, and make sure the QuickBooks balance matches it. If it doesn't, you may have unreconciled the wrong reconciliation, or there may be other unreconciled transactions in your account. Check your bank register for any transactions without a checkmark that should have been reconciled.

How to re-reconcile after undoing a reconciliation

Once you've undone a reconciliation and fixed whatever error prompted you to undo it, you can re-reconcile. Go back to the Reconcile page, select your account, and enter the same ending date and ending balance from your bank statement. QuickBooks will show you all the unreconciled transactions again.

This time, match only the transactions that actually appear on your bank statement. If you're re-reconciling because you matched the wrong transactions the first time, take extra care to verify each one against your statement. When you're done, click Reconcile to complete the process. Your account balance will update to reflect the new reconciliation.

If you unreconcile by mistake and want to go back to the way things were, you can re-reconcile the same transactions using the same ending date and balance. QuickBooks keeps a record of what was matched before, so you're not starting from scratch — you're just re-doing the match with the information you already have.

Common reasons to undo a reconciliation

The most common reason people undo reconciliations is that they matched a transaction to the wrong bank entry. For example, you might have two deposits of similar amounts on the same day, and QuickBooks matched one of them to the wrong transaction in your register. Undoing the reconciliation lets you fix that mismatch without having to manually reverse anything.

Another frequent reason is discovering a duplicate transaction. If you imported the same bank transaction twice — once through a direct connection and once through a CSV file — you might not notice until after reconciliation. Undoing lets you remove the duplicate and re-reconcile cleanly.

Sometimes you undo a reconciliation straightforward because you want to double-check your work before closing out a month. If you reconciled quickly and want to verify every match, unreconcile, review, and reconcile again. This is a safe way to catch errors before they compound.

Frequently Asked Questions

Can I undo a reconciliation from six months ago?

Yes, but you'll need to do it manually. The Unreconcile button typically only works for reconciliations from the last two months. For older ones, go to your bank register, find the transactions from that reconciliation period, and uncheck them one by one. It's slower, but it works.

Will undoing a reconciliation affect my tax records?

Undoing a reconciliation only changes which transactions are marked as reconciled in QuickBooks — it does not delete or change the transactions themselves. Your actual income and expense records stay the same. However, if you're undoing a reconciliation from a closed tax year, check with your accountant before making changes.

What if I unreconcile and my balance doesn't match my bank statement?

Check your bank register for transactions without a checkmark. These are unreconciled transactions that may belong to an earlier reconciliation or may be pending. Verify each one against your bank statement. If a transaction appears on your statement but not in QuickBooks, you may need to add it manually before reconciling again.

Can I undo just part of a reconciliation?

Yes. Use the bank register method to uncheck individual transactions rather than using the Unreconcile button. This lets you keep some transactions reconciled while undoing others. This is useful if you only need to fix one or two matches and the rest were correct.

Do I lose any information when I unreconcile?

No. Unreconciling removes the reconciliation status from transactions, but the transactions themselves stay in your register with all their details intact. You can re-reconcile them later, and QuickBooks will remember what was matched before.
