Ever looked at your payslip and wondered why the amount reaching your bank account is lower than your gross salary? One of the main reasons is PAYG withholding. Your employer deducts an amount for tax before paying your wages.
PAYG withholding is Australia’s system for collecting income tax progressively throughout the year. Instead of dealing with your entire tax liability at the end of the financial year, amounts are withheld from your salary or wages as you earn them. These amounts are then taken into account when your final tax position is calculated.
Understanding how PAYG tax works makes it easier to read your payslip, estimate your take-home pay and understand what happens to the tax deducted from your earnings.
How Does PAYG Withholding Work?
PAYG withholding starts when you begin employment and continues each time you are paid.
Step 1: You Provide Your Tax Information
When starting a job, you usually provide your employer with information such as your Tax File Number (TFN) and whether you are claiming the tax-free threshold.
Your employer uses the relevant information to determine which withholding rules apply to your payments.
This is important because two employees earning the same gross salary may not always have exactly the same amount withheld if their tax circumstances are different.
Step 2: Your Employer Calculates Your Gross Pay
Your employer calculates how much you earned during the pay period before tax and other deductions.
Your gross earnings may include:
- Regular salary or wages
- Overtime
- Bonuses or commissions
- Allowances
- Other taxable payments
This amount becomes the starting point for calculating PAYG withholding.
Step 3: Your PAYG Withholding Is Calculated
Your employer calculates how much to withhold using the applicable ATO withholding schedules, tax tables or payroll formulas.
The amount can depend on factors such as:
- How much you earn
- Whether you are paid weekly, fortnightly or monthly
- Whether you claim the tax-free threshold
- Information you have provided to your employer
- Any applicable withholding adjustments
Because Australia uses a progressive income tax system, higher earnings generally result in a higher amount of tax being withheld.
Step 4: PAYG Is Deducted From Your Pay
Once the PAYG amount has been calculated, your employer deducts it before paying you.
The basic process is:
Gross earnings → PAYG withholding → Other applicable deductions → Take-home pay
The amount remaining is your net pay, commonly called your take-home pay.
Step 5: Your Employer Reports and Pays PAYG Withholding
Employers generally use Single Touch Payroll (STP) to report information such as salary or wages and PAYG withholding when employees are paid.
The employer must also report and pay withheld amounts to the ATO according to their PAYG withholding and activity-statement obligations.
This means the tax deducted from your salary is recorded against your tax information and contributes towards your final tax position for the financial year.
How Much Tax Is Withheld From Your Salary in Australia?
No single PAYG withholding amount applies to every employee. The tax withheld from your salary in Australia depends mainly on your earnings, pay frequency and the tax information applying to your employment.
| Pay Frequency | How PAYG Withholding Works |
| Weekly | Withholding is calculated from each weekly payment |
| Fortnightly | Withholding is calculated from each fortnightly payment |
| Monthly | Withholding is calculated from each monthly payment |
Your withholding can also change between pay periods.
For example, earning overtime or receiving a bonus may increase your gross pay for that period, which can change the amount withheld.
This is why comparing only your annual salary with one PAYG figure does not always give an accurate picture of what will appear on every payslip.
Example: How PAYG Withholding Affects Your Pay
Suppose Alex earns $80,000 per year and is paid fortnightly.
Before tax and other deductions, the approximate gross fortnightly salary is:
$80,000 ÷ 26 = $3,076.92
Alex’s employer then uses the applicable PAYG withholding calculation based on the information Alex has provided.
The process looks like this:
$3,076.92 gross pay → PAYG withholding → Other applicable deductions → Net fortnightly pay
The exact amount of PAYG withheld depends on the relevant withholding rules and Alex’s circumstances, so it should not simply be estimated using one flat tax percentage.
This example also explains why an $80,000 annual salary does not mean $80,000 is deposited into the employee’s bank account over the year. PAYG withholding reduces each payment before the employee receives their take-home pay.
What Are Employer PAYG Obligations?
Employers play the main administrative role in the PAYG withholding process.
Depending on their circumstances, employer PAYG obligations can include:
- Registering for PAYG withholding
- Collecting the required employee tax information
- Calculating the correct amount to withhold
- Withholding tax from applicable payments
- Reporting payroll information through STP
- Reporting withheld amounts through the appropriate activity statement
- Paying required withholding amounts to the ATO
- Keeping accurate payroll records
Employers need to distinguish between withholding tax from an employee’s pay and reporting payroll information. STP reports payroll information to the ATO, while PAYG amounts must also be dealt with through the employer’s relevant reporting and payment obligations.
Frequently Asked Questions
Why is PAYG tax deducted from my salary?
PAYG withholding allows tax to be collected progressively from your earnings throughout the year rather than leaving the entire amount until tax time. Your employer deducts the applicable amount before paying you.
Is PAYG withholding my final tax amount?
Not necessarily. PAYG is tax withheld during the year. Your final tax position is calculated using your annual taxable income, deductions, offsets and other applicable tax information.
Does PAYG withholding account for the Medicare levy?
PAYG withholding calculations can account for Medicare levy settings through the relevant withholding rules. However, your actual Medicare levy liability is determined as part of your final income tax assessment and depends on your circumstances.
Can my PAYG withholding change from one payday to another?
Yes. Changes in earnings, such as overtime, bonuses, commissions, or other taxable payments, can affect the amount withheld for a particular pay period.
Do I still need to lodge a tax return if PAYG has been withheld?
PAYG withholding does not, by itself, determine whether you need to lodge a tax return. Your lodgment requirement depends on your income and other circumstances for the financial year.
Final Thoughts
PAYG withholding spreads income tax collection across the financial year instead of leaving the full amount until the end.
In simple terms, how PAYG tax works is straightforward: your employer calculates your gross earnings, works out the applicable PAYG withholding, deducts it before paying you, reports the payroll information and meets their reporting and payment obligations with the ATO.
