Australia — Business: Social Security
Australia does not have a traditional "social security payroll tax" system for employers — instead, employers must make compulsory superannuation guarantee (SG) contributions into an employee's nominated super fund. The SG rate reached 12% of ordinary time earnings from 1 July 2025, the final step of a legislated series of increases, with no further scheduled rate rises. From 1 July 2026, "Payday Super" requires contributions to be paid within days of each pay run rather than quarterly.

Why this matters
Underpaying or late-paying superannuation triggers the non-deductible Superannuation Guarantee Charge (SGC), plus interest and administration fees, and is a common compliance trap for new employers.
Key facts
- Businesses that pay employees must register with the ATO for PAYG withholding and pay superannuation guarantee contributions on their behalf; the maximum contribution base for SG purposes is AUD 270,830 for 2026-27.
- The superannuation guarantee rate is 12% of ordinary time earnings, effective from 1 July 2025 — this is the final scheduled increase under current legislation.
- From 1 July 2026, the "Payday Super" reform requires super to be paid within 7 business days of each pay day, replacing the previous quarterly payment cycle.
Steps
- Step 1: Determine Social Security Obligations — Review the Australian Government's website and consult with an accountant or tax professional to determine the social security obligations specific to your business, including superannuation contributions and any applicable taxes.
- Step 2: Register with the ATO — Register your business with the ATO for tax purposes, which includes obtaining an Australian Business Number (ABN) and a Tax File Number (TFN).
Costs

- ATO registration: free
- Superannuation Guarantee Charge (if contributions are late or underpaid): the shortfall amount plus interest and an administration fee — not tax-deductible

Required documents
