PAYG withholding is calculated per pay period using ATO tax tables (Schedule 1 -- NAT 1004) or the Statement of Formulas. The employer applies the appropriate coefficients based on weekly/fortnightly/monthly earnings.
Resident Individual Tax Rates (2025--26)
| Taxable Income (AUD) | Rate | Tax on This Income |
|---|---|---|
| 0 -- 18,200 | 0% | Nil |
| 18,201 -- 45,000 | 15% | 15c for each $1 over $18,200 |
| 45,001 -- 135,000 | 30% | $4,020 plus 30c for each $1 over $45,000 |
| 135,001 -- 190,000 | 37% | $31,020 plus 37c for each $1 over $135,000 |
| 190,001+ | 45% | $51,370 plus 45c for each $1 over $190,000 |
These rates exclude the Medicare levy (2%). From 1 July 2026 the rate on $18,201--$45,000 dropped from 16% to 15% (Treasury Laws Amendment (More Cost of Living Relief) Act 2025); it drops again to 14% from 1 July 2027.
Medicare Levy
| Item | Detail |
|---|---|
| Standard rate | 2% of taxable income |
| Low-income threshold (single) | No levy up to $28,011; reduced levy $28,012--$35,014 |
| Low-income threshold (family) | No levy up to $47,238; reduced $47,239--$59,048 |
| Medicare Levy Surcharge | 1.0%--1.5% additional for high earners without private hospital cover |
Australia does not have a separate employee social security contribution. The Medicare levy (2%) serves a similar function but is collected through PAYG withholding, not as a separate line item.
Employee-Side Deductions Summary
| Deduction | Rate | Ceiling | Notes |
|---|---|---|---|
| PAYG income tax | Progressive (see above) | No ceiling | Includes Medicare levy in tax tables |
| STSL repayment | 1%--10% (income-based) | No ceiling | Only if employee has HELP/STSL debt |
| Salary sacrifice (super) | Voluntary | Concessional cap $32,500/year (2026-27) | Pre-tax; reduces PAYG withholding base |
There is no employee-paid social insurance premium equivalent to NIC (UK) or social security tax (US).
|---| | SG rate | 12% of qualifying earnings | | Maximum contribution base | $270,830 per year (ANNUAL, year-to-date basis; quarterly base abolished for earnings paid from 1 Jul 2026) | | Minimum earnings threshold | Abolished (no $450/month threshold from 1 Jul 2022) | | Payment deadline | Received by the employee's fund within 7 business days of each payday (clearing house receipt does not count) | | Eligible employees | All employees 18+; under-18s working 30+ hours/week |
Deadline exceptions: new employee / new fund -- 20 business days for the first contribution; out-of-cycle payments (bonuses) ride with the next regular payday's deadline; ATO exceptional-circumstances determinations -- 20 business days.
Legacy: quarterly due dates (28 Oct/28 Jan/28 Apr/28 Jul) apply only to earnings paid up to 30 June 2026; the final quarterly deadline was 28 July 2026. The ATO Small Business Super Clearing House closed permanently on 1 July 2026 -- small employers now use payroll-software super payments or commercial clearing houses.
12% is the final scheduled SG rate (reached 1 July 2025). No further increases are planned.
For earnings paid from 1 July 2026, SGC is ATO-assessed per payday (no SGC statement is lodged; the ATO matches STP data against fund reporting). Components:
The redesigned SGC is tax-deductible (GIC on late SGC and the late payment penalty are not). Old-regime SGC for quarters before 1 July 2026 remains non-deductible. Unpaid SGC 28 days after assessment triggers a Notice to Pay, then a 25% or 50% late payment penalty. First-year ATO approach: PCG 2026/1.

| Failure to withhold PAYG | Employer liable for amount that should have been withheld |
| Late BAS/IAS lodgement | General interest charge (GIC) + potential failure-to-lodge penalty |
| Payslip non-compliance | Up to $16,500 per contravention (individual); $82,500 (body corporate) |
Annual salary $85,000. Paid monthly. No STSL debt.

Annual salary $120,000. Sacrifices $10,000/year to super.
Employee earning $65,000 with HELP debt. STSL repayment rate from Schedule 8 tables: approximately 4.5%. Annual repayment: $65,000 × 4.5% = $2,925, withheld progressively via PAYG.
