The first pay run is a milestone — and the moment a new set of obligations quietly switches on. Withholding tax from wages is not something you opt into when the business feels ready; it starts with the first payment to an employee. Most of the mechanics are handled by software these days, which is exactly why the parts that are not automated are where the problems hide.
Register before the first pay run
Before making any payment you need to withhold from, the business must be registered for PAYG withholding. Registration is straightforward — through Online services, the Australian Business Register, or your agent — but it has to happen first, not at BAS time. Paying wages for months before registering is a surprisingly common discovery when a new client's file is reviewed.
Working out how much to withhold
The amount withheld from each pay comes from the ATO tax tables, driven by what the employee declares: their TFN, whether they claim the tax-free threshold, and any study loan. In practice, STP-enabled software such as Xero or MYOB calculates this automatically once the employee's details are entered correctly — the software is only as accurate as the declaration behind it. Every new employee should complete a TFN declaration, either on paper or through ATO online services, before their first pay. If an employee does not provide a TFN, you are generally required to withhold at the highest rate — check the current rate — which is an uncomfortable conversation better had early.
Reporting and paying: W1 and W2
Each pay run is reported to the ATO through Single Touch Payroll as it happens. The money itself is remitted through the BAS: label W1 reports total gross wages and other payments subject to withholding, and label W2 reports the amount actually withheld. Smaller withholders generally pay quarterly with the BAS, while larger withholders move to monthly — the ATO advises you when your cycle changes. W1 and W2 need to reconcile to what the payroll software reported through STP; a mismatch is one of the first things a review will find.
Directors and family members are not exceptions
Director fees are subject to withholding just like wages, and they belong in STP and on the BAS. The same applies to wages paid to a spouse or family member: the employment must be genuine, the rate defensible for the work actually done, and the pay treated exactly like any other employee's — withholding, STP reporting and super included. Where withholding and reporting obligations are ignored entirely, the deduction for the payment itself can be at risk, which turns a bookkeeping shortcut into a real tax cost.
What we commonly see go wrong
- Wages paid before the business is registered for PAYG withholding, leaving a backlog to untangle.
- Director drawings reclassified as wages at year end with no withholding, no STP and no super along the way.
- No TFN declaration on file, so the software withholds on default settings nobody checked.
- W1 quietly missing categories such as director fees or allowances, so the BAS and the payroll records tell different stories.
A worked example
As an illustration: a company owner takes irregular amounts from the business all year, intending to sort it out later. At year end, the accountant is asked to call it wages. But no tax was withheld, nothing went through STP, and no super was paid — so the tidy-up now involves late reporting, potential loss of the deduction, and a super shortfall on top. The same money, run through payroll properly each month, would have cost nothing extra and created no exposure. The difference is not the amount; it is the process.
When to get help
If you are hiring your first employee, paying yourself or family members from a company, or you suspect W1 and W2 have drifted from what payroll actually shows, it is worth a review before the next BAS rather than after. These issues are almost always cheaper to fix in the quarter they arise.
Common questions
Do I need to register for PAYG withholding before hiring?
Yes — registration must be in place before you make the first payment you are required to withhold from. It can be done through Online services, the Australian Business Register, or your accountant, and it is much easier than unwinding unregistered pay runs later.
Does my accounting software work out the withholding for me?
STP-enabled software such as Xero or MYOB calculates withholding automatically from the ATO tax tables, but only from the details entered — TFN, tax-free threshold and loan flags. The calculation is only as good as the employee's declaration behind it.
Do I have to withhold from wages paid to my spouse or from director fees?
Yes. Director fees and genuine family wages are treated like any other wages — withholding, STP reporting and super all apply. Where those obligations are ignored entirely, the tax deduction for the payment itself can be at risk.
