When a payroll report is replaced¶

Most of the time, if a pay run needs a fix, your payroll software sends the ATO a small extra report to adjust it. But sometimes — when a whole report was sent in error, or was badly wrong — the software sends a corrected report that replaces the earlier one for that pay period instead.

Replacing a report changes the running totals the ATO holds for the year. Because your activity statement pre-fill is built from those totals, a replaced report can change the figures at W1 and W2. This lesson explains why, and what to do if it happens near statement time.

In one line

Replacing a payroll report changes the year-to-date figures the ATO holds, which can change your pre-filled W1 and W2 — so if you replace a report around statement time, re-check the pre-fill before you lodge.

Why this matters¶

The pre-filled W1 and W2 on your activity statement are not typed in by hand — the ATO builds them from the payroll reports it holds. If one of those reports is swapped for a corrected version, the totals behind the pre-fill move too.

If you had already looked at the pre-fill, or already saved a draft, the figure you remember may no longer match what your payroll now says. Lodging the old figure would report the wrong amount. A quick re-check catches that.

Understanding the concept¶

Your payroll keeps a year-to-date running total for each employee — the wages and tax added up across the year so far. Each report you send tells the ATO where those totals stand.

There are two ways to fix a report:

A small adjustment — an extra report that nudges the totals up or down.
Replacing the report — a corrected report that takes the place of a previous one for that pay period, rather than adjusting it.

When a report is replaced, the earlier version is set aside and the corrected one stands in its place. That changes the year-to-date figures the ATO holds. And since the ATO builds your pre-filled W1 and W2 from those figures, the pre-fill can change when a report is replaced.

The timing is what matters. If you replace a report around statement time — just before or while you are preparing your activity statement — the pre-fill you were looking at may no longer be current. The ATO keeps updating the pre-fill as new payroll information comes in, right up until you save or lodge the statement.

So the rule of thumb is simple: if you replaced a payroll report near statement time, re-open the statement and re-check the pre-fill against your own payroll before you lodge. Make sure W1 and W2 reflect the corrected figures, not the old ones.

For accountants & bookkeepers

This is the full file replacement case: a corrected pay report that replaces the last lodgment sent in error or with significantly inaccurate data, rather than a small adjustment. It restates the year-to-date position the ATO holds, which flows through to the W1 and W2 pre-fill built from processed reports. The ATO limits its use — it is not for routine corrections, cannot be used once later payroll reporting has changed the affected employees, and is capped to one per 24 hours. After any replacement near a lodgment, reconcile the refreshed pre-fill to the payroll register before lodging, and revise an already-lodged period if the totals moved.

Example¶

Jordan does the books for a landscaping business and is getting the quarterly BAS ready. He notices the last pay report went out with the wrong pay date and some wrong hours — the whole report is off, not just one line.

Rather than a small adjustment, Jordan has the payroll software send a corrected report that replaces the faulty one for that pay period. The corrected report carries the right wages and the right tax withheld.

Earlier that morning Jordan had glanced at the pre-fill and jotted the numbers down. Because he replaced a report, he goes back into the activity statement and re-checks. Sure enough, the pre-filled W1 and W2 have moved to reflect the corrected report. He compares the new figures against his payroll for the quarter, confirms they match, and only then lodges. Had he lodged from his earlier notes, he would have reported the old, wrong amount.

Common mistakes¶

Assuming the pre-fill stays put after you replace a payroll report — the year-to-date totals behind it can change.
Lodging from a figure you noted earlier, before a report was replaced.
Replacing a report near statement time and not re-opening the statement to re-check.
Not comparing the refreshed pre-fill against your own payroll totals before lodging.

How this works in myaccountant¶

In the app — when a payroll report is replaced with a corrected one, myaccountant re-checks the pre-filled W1 and W2 the next time you prepare the activity statement, and shows you the payroll totals to compare against so you can confirm the figures before you lodge.

Key points¶

Sometimes a corrected payroll report replaces an earlier one rather than adjusting it.
Replacing a report changes the year-to-date figures the ATO holds.
Those figures feed your pre-filled W1 and W2, so the pre-fill can change.
The ATO keeps updating the pre-fill until you save or lodge the statement.
If you replace a report around statement time, re-check the pre-fill before lodging.
Compare the refreshed figures against your own payroll totals to be sure.
