The ATO has released important updates to Single Touch Payroll Phase 2 reporting requirements. Understand what has changed, how it affects your business, and what you need to do to remain compliant.

What You Need to Know

  • Enhanced reporting requirements for employment types and income streams
  • New data elements for disaggregated salary and wage information
  • Clearer guidance on country codes and overseas employment
  • Updated child support deduction reporting requirements
  • All employers on STP Phase 2 by 1 January 2022 (with limited exemptions)

What is STP Phase 2?

Single Touch Payroll (STP) Phase 2 is an enhancement to the original STP system that requires employers to report more detailed information about their employees' pay, tax, and super to the ATO each time they run payroll.

STP Phase 2 provides the ATO with more granular data to help employees access government services more easily, improve compliance, and reduce the need for payment summaries (formerly known as group certificates).

Key Changes in the Latest Update

1. Enhanced Income Type Reporting

The ATO now requires more detailed categorisation of income types to help determine employee eligibility for government benefits and services. You must now separately report:

  • Salary and wages (disaggregated)
  • Allowances (with specific allowance types)
  • Bonuses and commissions
  • Directors fees
  • Lump sum payments (types A, B, D, and E)
  • Fringe benefits

2. Employment Basis Classification

You must now clearly identify the employment basis for each employee using one of these categories:

Full-time: Employees working standard full-time hours
Part-time: Permanent employees working less than full-time hours
Casual: Employees engaged on a casual basis
Labour hire: Workers supplied through labour hire arrangements
Other: Employees not fitting the above categories

3. Country Code for Overseas Employment

If you have employees working overseas or Australian residents working for foreign employers, you must now report the country where the work is performed using ISO 3166-1 alpha-3 country codes (e.g., AUS for Australia, NZL for New Zealand, USA for United States).

4. Child Support Deduction Updates

Enhanced reporting for child support deductions now requires:

  • Separate reporting of ongoing deductions versus arrears payments
  • Customer reference numbers for all child support deductions
  • Deduction amounts must match the amounts forwarded to Services Australia

5. Cessation Date Reporting

When an employee leaves your business, you must report their cessation date through STP. This helps the ATO and Services Australia determine when an employee may be eligible for government payments or services.

Who Needs to Comply?

All employers who report through STP must transition to STP Phase 2. This includes:

  • All employers: Regardless of business size (20+ employees, micro employers, and closely held payees)
  • All payroll systems: Software must be updated to support Phase 2 reporting
  • Limited exemptions: Only employers with an active STP deferral or exemption are excluded

What You Need to Do

To ensure compliance with STP Phase 2, follow these steps:

1. Update Your Payroll Software

Ensure you are using STP Phase 2 compliant software. Exacc is fully compliant with all STP Phase 2 requirements and automatically includes the latest ATO updates.

2. Review Employee Classifications

Check that all employees are correctly classified by employment basis (full-time, part-time, casual, labour hire, or other).

3. Set Up Income Type Categorisation

Configure your payroll to correctly categorise different income types (salary, allowances, bonuses, etc.) according to ATO requirements.

4. Update Overseas Employee Records

If you have employees working overseas, add the correct country code to their employment records.

5. Verify Child Support Details

Ensure child support customer reference numbers are correct and deductions are properly categorised as ongoing or arrears.

6. Test Your STP Reporting

Run a test STP submission to ensure all data is being reported correctly and accepted by the ATO.

Common Errors and How to Fix Them

Error: Invalid Employment Basis Code

Cause: Employee classification is missing or uses an invalid code.

Solution: Review each employee record and assign one of the five valid employment basis codes: full-time, part-time, casual, labour hire, or other.

Error: Missing Income Type Disaggregation

Cause: Total gross reported without breaking down into specific income types.

Solution: Configure pay items to automatically categorise income into the correct type (salary, allowances, bonuses, etc.).

Error: Invalid Country Code

Cause: Country code format is incorrect or uses an invalid code.

Solution: Use ISO 3166-1 alpha-3 country codes (three-letter codes like AUS, NZL, GBR).

Error: Child Support Customer Reference Number Missing

Cause: Child support deduction reported without required customer reference number.

Solution: Obtain the customer reference number from the Services Australia deduction notice and add it to the employee record.
