PAYG stands for "Pay As You Go" - the system where your employer withholds tax from your wages and sends it directly to the Australian Taxation Office (ATO). This means you pay tax throughout the year rather than a large sum at tax time.
Why PAYG Exists
- • Makes tax easier to manage - paid in small amounts each pay cycle
- • Provides steady revenue for government services
- • Reduces risk of a large tax bill at end of year
- • Ensures most people get a refund rather than owing money

How PAYG Works
When you start a job, you complete a TFN Declaration Form. This tells your employer how much tax to withhold from your pay. Each pay cycle, your employer:
- Calculates your gross pay (before tax)
- Calculates the PAYG tax to withhold based on ATO tables
- Deducts the tax amount from your pay
- Sends your net pay (after tax) to your bank account
- Sends the withheld tax to the ATO on your behalf
Example: Weekly Pay
- Gross pay: $1,200 per week
- PAYG tax withheld: $198
- Net pay (take-home): $1,002
- The $198 goes straight to the ATO as a credit against your annual tax liability.
PAYG Withholding vs PAYG Instalments
| Type | Who | How It Works |
|---|---|---|
| PAYG Withholding | Employees | Employer deducts tax from wages automatically |
| PAYG Instalments | Self-employed, investors | You pay tax directly to ATO quarterly |
The Tax-Free Threshold
The tax-free threshold is the amount of income you can earn each year without paying any tax. For 2024-25, this is $18,200.
Tax-Free Threshold = $18,200
If you earn $18,200 or less per year from all sources combined, you pay zero income tax. Every dollar above $18,200 is taxed according to the tax brackets.
Claiming the Tax-Free Threshold
When you complete your TFN Declaration, you're asked: "Do you want to claim the tax-free threshold?"
If You Claim It (YES)
- + Less tax withheld each pay
- + Higher take-home pay
- + Only claim from ONE employer
- + Best for your main job
If You Don't Claim It (NO)
- + More tax withheld each pay
- + Lower take-home pay
- + Use for second/third jobs
- + Reduces chance of tax debt
Warning: Multiple Jobs
If you have multiple jobs, only claim the tax-free threshold from your main employer (where you earn the most). Claiming it from multiple employers will result in too little tax being withheld, leading to a tax debt at the end of the year.
Tax Brackets 2024-25
Australia uses a progressive tax system, meaning higher income is taxed at higher rates. But only the portion of income in each bracket is taxed at that rate.
Australian Resident Tax Rates (2024-25)
| Taxable Income | Tax Rate | Tax on This Bracket |
|---|---|---|
| $0 - $18,200 | 0% | Nil (tax-free threshold) |
| $18,201 - $45,000 | 16% | 16c for each $1 over $18,200 |
| $45,001 - $135,000 | 30% | $4,288 + 30c for each $1 over $45,000 |
| $135,001 - $190,000 | 37% | $31,288 + 37c for each $1 over $135,000 |
| $190,001+ | 45% | $51,638 + 45c for each $1 over $190,000 |
Plus Medicare Levy of 2% on taxable income (with exemptions for low income).
Understanding Progressive Tax
Example: Earning $80,000
- First $18,200: $0 tax (tax-free)
- $18,201 to $45,000: $26,800 x 16% = $4,288
- $45,001 to $80,000: $35,000 x 30% = $10,500
- Total Tax: $14,788
- Medicare Levy: $80,000 x 2% = $1,600
- Total Tax + ML: $16,388
- Effective Tax Rate: 20.5%
Common Misconception
Many people think earning more will put "all their income" in a higher bracket. This is wrong. Only the income within each bracket is taxed at that rate. A pay rise will never leave you worse off after tax.
How PAYG Is Calculated
Employers use the ATO's tax tables to calculate PAYG withholding. The tables account for:
- Your pay frequency (weekly, fortnightly, monthly)
- Whether you claim the tax-free threshold
- Whether you have a HELP/HECS-HELP debt
- Whether you have a spouse
- Any additional tax you've requested to withhold
Weekly PAYG Examples (2024-25, claiming tax-free threshold)
| Weekly Gross | Annual Equivalent | PAYG Withheld | Take Home |
|---|---|---|---|
| $500 | $26,000 | $24 | $476 |
| $800 | $41,600 | $94 | $706 |
| $1,000 | $52,000 | $159 | $841 |
| $1,200 | $62,400 | $218 | $982 |
| $1,500 | $78,000 | $307 | $1,193 |
| $2,000 | $104,000 | $463 | $1,537 |

Understanding Your Payslip
Your payslip shows how PAYG tax affects your pay. Here's what to look for:
Sample Payslip Breakdown
Key Payslip Terms
- Gross Pay: Your total earnings before any deductions
- PAYG Withholding: Income tax sent to ATO
- Net Pay: What actually goes into your bank account
- Super: Paid separately by employer (not deducted from gross)
- Year-to-Date (YTD): Total amounts since 1 July
Common PAYG Situations
HECS-HELP Debt
If you have a HELP debt (student loan), extra tax is withheld once your annual income exceeds the repayment threshold ($54,435 for 2024-25). The repayment rate ranges from 1% to 10% of your income.
HELP Repayment Example
Income: $65,000/year
HELP repayment rate: 3%
Annual repayment: $1,950
Additional weekly deduction: ~$37.50
Second Job
For a second job where you don't claim the tax-free threshold, tax is calculated as if all income falls in the highest applicable bracket. This means roughly 32% tax on every dollar.
Irregular Hours
If your hours vary (casual work), PAYG is calculated based on each individual pay. This might result in over-withholding in higher-earning weeks, leading to a refund at tax time.
Salary Sacrifice
If you salary sacrifice into super, the sacrificed amount is taxed at 15% (super contributions tax) instead of your marginal rate. This reduces your PAYG withholding.
Refunds vs Tax Debts
At the end of the financial year (30 June), you lodge a tax return. The ATO compares:
- Total tax you should have paid (based on actual annual income)
- Total PAYG tax withheld during the year
Tax Refund
If too much tax was withheld, you get a refund. Common reasons:
- + Work-related deductions
- + Worked less than full year
- + Claimed private health rebate
- + Salary sacrifice reduced income
Tax Debt
If not enough tax was withheld, you owe the ATO. Common reasons:
- - Claimed tax-free threshold twice
- - Second job income
- - Investment income (no PAYG)
- - Didn't update TFN declaration
Avoiding a Tax Debt
- Only claim tax-free threshold from one employer
- Request additional tax withheld on your TFN declaration
- Set aside money from investment income
- Update your employer if circumstances change
