Australia · guidePAYG withholding: the employer's data obligations
The short answer
Pay as you go withholding (PAYG-W) is the system that requires an employer to register with the ATO, withhold tax from each employee's pay using the current withholding schedules, and report those amounts through Single Touch Payroll (STP) every pay run. The withheld totals surface on the business activity statement at labels W1 and W2 and are paid to the ATO on a cycle set by how much the business withholds each year, then confirmed for each employee through an STP finalisation declaration at year end. PAYG-W is separate from PAYG instalments, which prepay the business's own income tax rather than an employee's.
Key facts — verified dates on each
Registering for PAYG withholding
An entity that will make a payment covered by PAYG withholding — most commonly wages to an employee — must register for a PAYG withholding account with the ATO before the first such payment is made. This applies even in a pay period where nothing ends up being withheld, because the obligation attaches to being a payer, not to the size of the withholding.
Registration is done through the ATO's business registration channels: online through ATO or Business Registration Service channels, by phone, through a registered tax or BAS agent, or by lodging the paper application to register a PAYG withholding account. Most businesses that already hold an ABN add the PAYG withholding role to their existing registration rather than starting a separate entity record.
What gets withheld from a pay run, as a mechanism
Each pay run, the payer works out how much tax to withhold from an employee's gross pay using the ATO's withholding schedules — the tax tables that translate gross pay, pay frequency, and the employee's tax file number declaration (including any Medicare levy variation, HELP or other study and training loan debt, and claimed tax-free threshold) into a withheld amount. Those schedules are published and updated by the ATO and change from time to time, which is why the specific withheld dollar figure for a given pay is a payroll-software calculation against the current schedule, not a fixed rule that holds year to year.
The amount withheld is money that belongs to the employee's eventual income tax liability — the employer is holding it on the ATO's behalf, not the employer's own funds. If a payee has not provided a tax file number declaration, or has not quoted an ABN where one is required for a non-employee payment, withholding applies at a higher, ATO-set rate rather than the standard schedule rate.
Where PAYG withholding is reported: STP and the BAS
Since Single Touch Payroll became the standard reporting channel, an employer reports gross pay and the amount withheld to the ATO at, or before, each pay run — not in a separate return after the fact. STP-enabled payroll software sends this data directly to the ATO as part of running payroll, which is also what pre-fills the PAYG withholding labels on the business activity statement.
On the BAS, label W1 shows total gross payments from which the business is usually required to withhold — salary, wages, allowances, and similar payments — for the reporting period, and label W2 shows the total amount actually withheld from those payments. Because STP has already reported the underlying pay-run data, these two labels are typically pre-filled from STP figures rather than calculated from scratch when the BAS is prepared, though the figures are still reviewed before lodgment.
- W1 — total gross wages and other payments subject to withholding for the period
- W2 — total amount actually withheld from those payments
Paying withheld amounts to the ATO: the withholding cycle
How often withheld amounts are actually paid over to the ATO depends on how much the business withholds in a year, not on how often it runs payroll. The ATO sorts payers into three cycles based on that annual figure, and writes to a business if its cycle needs to change for the coming financial year.
A business does not choose its cycle freely — it is set by the withholding amount reported to the ATO, and moving between cycles happens through an ATO notification or a request the business lodges if its withholding is trending toward a different band.
- Small withholder — up to $25,000 withheld a year: reports and pays quarterly, aligned with the quarterly BAS due dates
- Medium withholder — $25,001 to $1,000,000 withheld a year: reports and pays monthly through the activity statement
- Large withholder — more than $1,000,000 withheld a year: pays electronically within a matter of days of the pay run, using a unique payment reference number rather than the standard BAS cycle
Annual reconciliation: STP finalisation
PAYG withholding is settled for each employee, for the year, through the STP finalisation declaration rather than through a separate PAYG withholding annual report. For arm's length employees the finalisation declaration is due 14 July following the end of the financial year; where a business has closely held payees, that group has until 30 September. Finalisation is what changes an employee's income statement in ATO online services from year-to-date figures to "tax ready," and it is what the employee's own tax return pre-fills from.
Finalisation is a confirmation step, not a fresh calculation — it declares that the amounts already reported pay run by pay run through the year are complete and correct. A business running PAYG withholding cleanly through the year, with STP data checked each pay cycle, generally reaches finalisation with nothing left to reconcile.
PAYG withholding versus PAYG instalments
PAYG withholding and PAYG instalments share a name and both feed the same activity statement, but they cover different tax and different taxpayers. PAYG withholding collects tax from payments the business makes to someone else — employees, and in some cases contractors or other payees — and remits it against that payee's eventual tax liability. PAYG instalments are prepayments toward the business's or individual's own income tax for the current year, based on the ATO's estimate from the last lodged tax return.
On the activity statement, PAYG withholding shows at the W-series labels described above; PAYG instalments show at separate labels (commonly T1 and T7, depending on the instalment method) that have nothing to do with wages withheld. A business can have both obligations at once — withholding tax from its employees' pay and separately prepaying its own income tax — and the two amounts are calculated and reported independently.
Where CapEasy's work fits, and where it stops
CapEasy is a bookkeeping and accounting firm; registered BAS and tax agent work runs through the business's own registered tax or BAS agent. Our bookkeeping work for Australian clients keeps payroll records reconciled to the general ledger and the underlying data current, so PAYG withholding figures flowing into STP and the BAS are drawn from clean books rather than reconstructed under deadline pressure.
Ascertaining or advising on a BAS or tax position, determining what should be withheld from a specific payment, lodging the BAS, and dealing with the ATO on a client's behalf are handled by the business's registered tax or BAS agent. Setting or verifying withholding amounts, confirming a PAYG withholding cycle, and preparing or lodging the activity statement are matters for the business's registered tax or BAS agent.
The figures, and when we checked them
These numbers change by year or by notification. Each one shows the date we last verified it against the source — if that date looks old, check the source before relying on it.
Questions on this
What is PAYG withholding?
It is the system requiring an employer (or other payer covered by the rules) to withhold tax from payments such as employee wages and remit it to the ATO on the payee's behalf, reported through Single Touch Payroll and paid over on a cycle set by the annual withholding amount.
When does a business need to register for PAYG withholding?
Before the first payment it makes that PAYG withholding applies to — for example, before the first pay run to an employee. This applies even if no amount ends up being withheld from that first payment.
How is the amount withheld from a pay worked out?
Payroll software applies the ATO's current withholding schedules to the employee's gross pay, pay frequency, and tax file number declaration details. The schedules are set and updated by the ATO, so the exact withheld figure for a given pay depends on the schedule in force at the time.
What happens if an employee has not provided a tax file number declaration?
Withholding applies at a higher, ATO-set rate rather than the standard schedule rate until a valid declaration is provided.
Where does PAYG withholding show up on the BAS?
At label W1, total gross payments the business is usually required to withhold from for the period, and label W2, the total amount actually withheld. Both are typically pre-filled from Single Touch Payroll data.
How often does a business pay withheld amounts to the ATO?
It depends on how much is withheld a year: up to $25,000 a year pays quarterly, $25,001 to $1,000,000 pays monthly, and more than $1,000,000 pays electronically within days of each withholding event rather than on the standard BAS cycle.
Can a business choose its own PAYG withholding cycle?
No. The cycle is determined by the ATO from the annual withholding amount reported. The ATO notifies a business if its cycle needs to change, and a business can request to stay on its current cycle if it expects to remain under the relevant threshold.
How does PAYG withholding get reconciled for the year?
Through the STP finalisation declaration — due 14 July for arm's length employees and 30 September for closely held payees — which confirms the pay-run figures already reported through the year are complete for each employee.
Is PAYG withholding the same as PAYG instalments?
No. PAYG withholding is tax withheld from payments made to someone else, such as an employee. PAYG instalments are prepayments toward the paying business's or individual's own income tax, based on the ATO's estimate from the last tax return, and they appear on the activity statement at different labels.
Who decides how much to withhold or confirms a PAYG withholding cycle for a business?
The business's registered tax or BAS agent is the party who ascertains and advises on withholding amounts, cycle status, and BAS lodgment. Bookkeeping work can keep payroll records reconciled and STP data current so that determination is made from accurate figures.
