PAYG Withholding Records: What Small Business Owners Get Wrong and How to Fix It

Every time you pay an employee, a portion of their wages is withheld and held on behalf of the ATO. That amount gets reported through your BAS and paid across as part of your regular tax obligations.

For most businesses, PAYG withholding for small business runs in the background without much thought. But it is one of the most common sources of ATO debt in Australia and the problems almost always trace back to payroll records and bookkeeping that are not quite right.

This article focuses on the bookkeeping side of PAYG withholding - what clean records look like, where the gaps usually appear, and how to make sure your payroll and BAS figures stay in sync. For advice on your specific PAYG compliance obligations or what to do if you have a PAYG debt with the ATO, speak with your accountant.

What Good PAYG Withholding for Small Business Looks Like

Before looking at the gaps, it helps to be clear on what good PAYG bookkeeping actually involves.

Good PAYG withholding records mean:

• Every pay run has the correct withholding amount calculated and recorded in your payroll system

• Withholding amounts are tracked clearly and separately from other payroll costs

• PAYG figures from your payroll records match what is reported in STP for the same period

• BAS PAYG figures reconcile exactly to your STP and payroll records before lodgement

• Withholding amounts are set aside and available when BAS is due, not mixed with general operating funds
  

When all of this is in place, PAYG withholding runs smoothly. When any part of it breaks down, problems build up, often quietly, over several quarters.

Where PAYG Withholding Bookkeeping Gaps Usually Appear 

1. Payroll software not updated at the start of a new financial year

Tax withholding rates change. At the start of each financial year, payroll software needs to be updated to reflect current tax tables. If this does not happen, every pay run for the new year may be withholding the wrong amount.

This is a straightforward bookkeeping maintenance task, but it gets missed more often than it should. 2. New employees set up incorrectly

When a new employee joins, their TFN declaration, residency status, and tax treatment code need to be entered correctly in the payroll system. Errors in setup flow through to every pay run for that employee.

A common example: a new employee's TFN declaration is not processed before their first pay run, so withholding defaults to the no-TFN rate, which is significantly higher than it should be. Reviewing new employee setup before the first pay run prevents these errors.

For questions about which tax treatment code or scale applies to a specific employee, speak with your accountant before processing.

3. STP and BAS PAYG figures not reconciled

This is one of the most common and most consequential bookkeeping gaps.

Your STP reports and your BAS must show the same PAYG withholding figures for the same period. When they do not match - because of payroll adjustments made after an STP submission, manual BAS entries, or payroll periods that do not align neatly with BAS quarters - the ATO can see the discrepancy.

Reconciling STP and BAS PAYG figures before every BAS lodgement is not optional. It should be a standard step in your bookkeeping process.

4. Different pay types not set up with correct withholding rules

Not all payments to employees are withheld in the same way. Whether a specific payment type should be withheld at a different rate is a question for your accountant. The bookkeeping issue is making sure those rules, once confirmed, are correctly set up in your payroll software and applied consistently.

If you are unsure how a particular pay category should be treated, check with your accountant before processing the payment.

5. Payroll records and actual bank payments not matching

A common bookkeeping issue is where payroll records show PAYG being withheld correctly, but the amounts being paid to the ATO through BAS do not match. This can happen when BAS is prepared from memory or estimates rather than from reconciled payroll records.

The fix is straightforward: BAS PAYG withholding should always be taken directly from reconciled payroll records, not entered manually.

6. Withholding amounts not treated as separate from operating cash

PAYG withholding is not business income. It is an amount held on behalf of employees' tax obligations. When it is mixed with general operating funds and spent on business expenses, the BAS obligation becomes difficult to meet.

Tracking PAYG withholding separately in the bookkeeping - so it is always visible and accounted for - is the most reliable way to make sure it is available when BAS is due.

What to Do If Your PAYG Records Have Gaps 

If your payroll records and BAS PAYG figures have not been reconciled regularly, or if you suspect there are errors in how withholding has been calculated, the right approach is to identify and correct the gaps proactively, ideally before the ATO does.

Your bookkeeper can help you review payroll records, reconcile STP and BAS figures, and identify where corrections may be needed. If the gaps are significant, involve your accountant. They can advise on the compliance implications and how best to proceed.

For businesses that already have a PAYG debt with the ATO, your accountant is the right first call. Once you know what you are dealing with, your bookkeeper can help get the underlying records in order.

Frequently Asked Questions About PAYG Withholding

What is PAYG withholding?

PAYG withholding is the tax deducted from employee wages and reported and remitted to the ATO through your BAS. Your accountant can advise on your specific withholding obligations. From a bookkeeping perspective, it needs to be tracked clearly in your payroll records and reconciled against your BAS each quarter.

How often do I need to report and pay PAYG withholding?

Most small businesses report and pay quarterly through BAS. Some businesses with higher withholding obligations report monthly. Your accountant or the ATO can confirm your reporting frequency. The bookkeeping task is making sure records are reconciled before each reporting period.

What happens if my STP and BAS PAYG figures do not match?

The ATO compares these figures automatically. A discrepancy may trigger follow-up. If you notice a mismatch, your bookkeeper can help you identify the cause and reconcile the records. Your accountant can advise on how to correct it and any compliance implications.

Do different types of payments have different withholding rates?

Yes. Some payments such as bonuses, termination leave payouts, and certain allowances have different withholding treatment. Your accountant can confirm the correct treatment for specific payment types. Once confirmed, your bookkeeper can make sure your payroll software applies those rules correctly and consistently.

What if I cannot pay PAYG withholding when BAS is due?

This is a question for your accountant. They can advise on your options. From a bookkeeping perspective, keeping withholding amounts tracked separately from operating funds so they are always visible helps prevent this situation from arising.

How do I know if my payroll withholding setup is correct?

The most reliable check is to reconcile STP submissions against BAS PAYG figures for each period and confirm they match. Your bookkeeper can help you do this review and flag anything that does not look right for your accountant to assess.
