If you manage payroll in Australia, you already know the complexity of multi-state payroll tax compliance. The challenge isn’t understanding the rules - it’s getting your payroll system to apply them correctly.
You’ve likely seen it before:
-
An employee lives in NSW but works in QLD.
-
The system defaults to their home address for payroll tax.
-
You know it’s wrong, but fixing it requires manual overrides and spreadsheet gymnastics.
You’re doing the right thing for compliance – but your payroll system is making you work too hard to get there.
Why payroll systems struggle with multi-state payroll tax
Multi-state payroll tax is a real-world complexity that most payroll systems aren’t built to handle well.
Common pain points include:
-
One-size-fits-all logic that uses employee home addresses, not work location.
-
Difficulty splitting earnings across multiple states within the same pay period.
-
No link between pay elements and payroll tax totals by jurisdiction.
Payroll managers know the rules, but the tools force them into workarounds. The result? More admin, more risk, and less time for strategic work.
Four essentials for multi-state payroll tax compliance
1. Flexible Location Tracking
Payroll tax should be based on the employee’s work location per pay period, not just a static home or office address.
2. Pay Element-Level Allocation
Each allowance, overtime payment, or bonus must be assigned to the correct state to ensure accurate totals.
3. Accurate GL Mapping
Payroll tax costs need to be assigned correctly to cost centres and reporting dimensions. Read more about payroll GL mapping best practices.
4. Clear Reporting
Managers need breakdowns of payroll tax by state, pay element, and employee for easy reconciliation. Explore how Affinity supports real-time reporting & workforce insights.
