Understanding STP Phase 2
Single Touch Payroll (STP) Phase 2 represents a significant evolution in payroll reporting for Australian businesses. Introduced by the ATO, Phase 2 expands reporting requirements to include additional information about employee payments, tax withholding, and superannuation. This comprehensive guide helps you understand your obligations and implement compliant processes.

Common STP Phase 2 Questions
Q.When is STP Phase 2 mandatory?
STP Phase 2 became mandatory for substantial employers (20+ employees) from January 1, 2022, and for all other STP reporters from January 1, 2023. However, the ATO has provided transitional arrangements for businesses needing more time.
Q.What happens if I miss the deadline?
The ATO has been taking a supportive approach during the transition period. However, ongoing non-compliance may result in penalties. Contact the ATO early if you anticipate difficulties meeting requirements.
Q.Do I need new payroll software?
Most modern payroll software has been updated for Phase 2. Check with your provider to ensure your version supports all Phase 2 requirements. Some older systems may require upgrades or replacement.
Q.How do I classify employment basis correctly?
Employment basis must reflect the actual employment arrangement: full-time (regular hours), part-time (regular but fewer hours), casual (irregular hours, casual loading), or labour hire. Misclassification can lead to compliance issues.
Q.What are disaggregated PAYG amounts?
Phase 2 requires separate reporting of tax withheld for different payment types (salary/wages, allowances, bonuses, etc.) rather than a single total. This provides the ATO with more detailed information.
