Pay-as-you-go (PAYG) is an Australian tax system designed to collect income tax from employees and businesses throughout the year rather than in a lump sum at the end of the financial year. It is a mechanism for prepaying tax obligations, ensuring a smoother cash flow for the government and avoiding large tax bills for taxpayers.
The PAYG system encompasses two main components: PAYG withholding and PAYG instalments. In this article, we look at the breakdown of each component and its implications for business owners in Australia.
PAYG withholding requires businesses to withhold tax from payments they make to others, including:
Employee salaries and wages
Payments to contractors who don’t provide an Australian Business Number (ABN)
Certain supplier payments, such as for goods or services
Employer Obligations
Employers must register for PAYG withholding with the Australian Taxation Office (ATO) before hiring employees. They are responsible for deducting tax from employee salaries and remitting it to the ATO. Additionally, employers must provide employees with a PAYG payment summary (also known as a Group Certificate) at the end of the financial year.
“PAYG is how the ATO collects tax throughout the year — instead of one big bill at the end of the financial year.”
The amount of tax to withhold depends on various factors, such as employee salary, tax brackets, and individual tax offsets. The ATO provides tax tables to guide employers on the correct withholding amounts. Employers should regularly update these tables to reflect legislative changes.
Business owners report PAYG withholding through their Business Activity Statements (BAS). These statements outline tax obligations, such as Goods and Services Tax (GST), PAYG withholding, and PAYG instalments. Depending on their turnover and reporting frequency, business owners must lodge their BAS with the ATO at regular intervals.
Along with PAYG withholding, employers are responsible for paying superannuation contributions to their employees. This is a separate obligation from PAYG but is closely related, as failure to meet either can lead to penalties and interest charges from the ATO.

PAYG instalments require businesses and individuals to prepay their income tax throughout the year rather than wait until the financial year’s end. This system helps businesses manage cash flow by spreading tax payments over multiple periods.
Businesses and individuals may need to pay PAYG instalments if their annual business or investment income exceeds a certain threshold. The ATO will notify taxpayers when they need to start paying instalments. PAYG instalments are commonly paid by:
There are two methods for calculating PAYG instalments: the instalment rate method and the instalment amount method.
Instalment Rate Method: The ATO provides a specific instalment rate based on the previous year’s tax return. Businesses apply this rate to their instalment income to determine the amount to pay.
Instalment Amount Method: The ATO sets a predetermined amount based on the previous year’s tax return for each instalment period. This method is more straightforward but less flexible.
Reporting PAYG Instalments
Businesses and individuals report their PAYG instalments through their BAS. The frequency of BAS reporting depends on the business’s size and turnover. The options include:
Quarterly: For businesses with annual turnover below a certain threshold
Monthly: For larger businesses with a higher annual turnover
Annually: For certain individuals and small businesses
“The PAYG system comprises two parts — PAYG withholding and PAYG instalments — covering wages, contractor payments, business and investment income.”
BAS is the key reporting document for business owners regarding their tax obligations, including PAYG withholding, PAYG instalments, GST, and other taxes. Businesses must lodge their BAS by the due date to avoid penalties and interest charges.
A BAS generally contains the following sections:
GST: Details of GST collected and paid during the reporting period
PAYG Withholding: Amount of tax withheld from employees and other payees
PAYG Instalments: Prepaid tax instalments for business income
Other Taxes: May include Fringe Benefits Tax (FBT) instalments
BAS lodgement can be completed online through the ATO’s Business Portal, using accounting software, or by mailing a paper form. Businesses must ensure accurate record-keeping to facilitate BAS preparation and compliance.
The frequency of BAS reporting determines the due dates:
Quarterly BAS: Due on the 28th day of the month following the quarter (except the December quarter, due on the 28th of February)
Monthly BAS: Due on the 21st of the following month
Annual BAS: Due with the income tax return
Businesses can apply for an extension if they face difficulties meeting these deadlines, but avoiding delays is advisable to prevent penalties.
The PAYG system in Australia is a comprehensive method for prepaying tax obligations, ensuring that businesses and the government maintain a stable cash flow throughout the year. Business owners must understand their responsibilities regarding PAYG withholding, PAYG instalments, and Business Activity Statements (BAS) reporting to ensure compliance and avoid penalties.
Accurate record-keeping, deadline compliance, and regular consultation with accounting professionals are essential for business owners to navigate the PAYG system effectively.

As Director and Business Advisor, Marius uses his accounting expertise and empathetic skills to work directly with business owners and help them feel at ease with their finances.
Marius saw a common need in clients that just wasn’t being met by accounting providers.
That need was for clear, open communication and streamlined accounting services that didn’t come padded out with any unnecessary features.
Business owners just don’t have time to compare different accounting firms to see which one has the best packages with the best inclusions (many of which they would pay for but never use).
If you employ staff or pay directors, PAYG withholding is not optional — it’s a fundamental part of running a compliant business in Australia.
Using reliable payroll software and correct tax tables helps ensure the right amounts are withheld and reported, reducing the risk of errors.
PAYG amounts don’t belong to the business. Setting funds aside regularly helps avoid cash flow pressure when BAS payments are due.

PAYG (Pay As You Go) withholding is the system where businesses withhold tax from payments made to employees, directors and some contractors, and send those amounts to the ATO on their behalf.
You must register for PAYG withholding if you pay wages or salaries to employees, make payments to company directors, or pay contractors who don’t quote an ABN.
The amount depends on the employee’s earnings and tax circumstances. Employers use the ATO tax tables or payroll software to calculate the correct withholding amount.
PAYG withholding is reported and paid through your Business Activity Statement (BAS), usually monthly or quarterly, depending on your reporting cycle.
Late or missed payments can result in penalties, interest charges and, in serious cases, director penalty notices. Staying up to date is critical for compliance.
