When the payment or balance does not match¶

You paid your Activity Statement, but the amount does not seem to match, or your Australian Taxation Office (ATO) account balance looks wrong. Before worrying, it is worth knowing that most of these mismatches have a simple cause: the wrong reference number, normal processing time, or a refund being used to reduce another debt. This lesson walks through the calm steps to check, and when to pick up the phone.

In one line

Check you used the right payment reference number, allow for processing time, and remember a refund can be offset against other tax debts — then contact the ATO if it still does not add up.

Why this matters¶

A payment that does not show, or a balance that looks off, is stressful — it can feel like money has gone missing. In most cases it has not. Knowing the usual causes lets you check calmly and avoid paying twice or chasing something that is simply still processing.

Understanding the concept¶

When you pay the ATO, you use a payment reference number (PRN). The ATO explains that you have different PRNs for different types of tax — for example, one PRN for income tax and a different one for your Activity Statement. If you pay using the wrong PRN, the money can land against the wrong account, so it does not show where you expect. Using the correct PRN is the first thing to check.

Second, payments are not instant. The ATO notes it can take a few business days for a payment you have made to become visible on your account. So a balance that still looks unpaid the same day may simply be a payment that has not finished processing.

Third, if you were expecting a refund and it did not arrive, it may have been offset. The ATO explains that where you have a debt on another account, it can use a credit or refund from one account to reduce that debt — this is called offsetting and it is required by law. For example, a GST credit may be used to reduce an income tax debt. Once your debts are covered, the ATO refunds anything left.

So the calm steps are:

Check the PRN you used matches the one for your Activity Statement.
Allow processing time — give a payment a few business days to appear.
Check for an offset — a refund may have gone towards another debt.
Contact the ATO if the amounts still do not add up after these checks.

For accountants & bookkeepers

Each ATO account has its own PRN, and paying with the wrong one is a common cause of "missing" payments and can trigger unnecessary follow-up. An account balance may also include amounts not yet due, which can make it look higher than the current statement. Offsetting is applied automatically across accounts, so a client's expected refund may appear as a reduced debt elsewhere rather than a cash refund.

Example¶

Sam lodges an Activity Statement and pays it straight away, but uses the PRN from an old income tax notice by mistake. A few days later the Activity Statement still shows as unpaid, and Sam nearly pays again.

Instead, Sam works through the steps. First, the PRN — and there it is: the payment went against the income tax account, not the Activity Statement. Sam also gives it a couple of business days to be sure nothing is still processing, then contacts the ATO to have the payment matched to the right account. No second payment needed — the money was never lost, just pointed at the wrong place.

Common mistakes¶

Paying with the wrong PRN, so the money lands against another account.
Assuming a payment is missing before allowing a few business days to process.
Expecting a full refund when part or all of it was offset against another debt.
Paying a second time before checking the PRN and processing time.

How this works in myaccountant¶

In the app — when an Activity Statement is ready, myaccountant shows what to pay along with the payment reference to use, so you can pay against the right account. If a balance still looks wrong after allowing for processing time, check it against your ATO account and contact the ATO.

Key points¶

You have different PRNs for different types of tax — use the right one.
A wrong PRN can send money to the wrong account.
Allow a few business days before assuming a payment is missing.
A refund can be offset against other tax debts you owe.
Contact the ATO if the amounts still do not add up.
