Adjust MCB Threshold Configuration (AUS)

Adjust MCB Threshold Configuration (AUS)

  • Security:
    Set Up: Payroll (Superannuation) - AUS
  • A Superannuation Default Configuration.
.
You can assign alternative Maximum Contributions Base (MCB) limits or MCB Excess rules to groups of workers using restriction rules within a superannuation configuration period. Workday evaluates a worker against each of the restriction rules in order until there’s a matching rule.
If you leave the grid blank, the legislated MCB rate from the advanced lookup table will apply, and the default MCB rule for the tenant will apply.
  1. Access the
    Maintain AUS Superannuation Configuration
     task.
  2. Access the superannuation configuration period that you’re adjusting the MCB configuration for, or add a new configuration period.
  3. In the
    Maximum Contributions Base Configuration
     grid, add a new row. Add the details and restriction.
    Option Description
    Annual Contribution Base
    Enter the MCB limit per annum. Qualifying Earnings (QE) over the MCB limit is subject to the MCB rule.
    Exceeds MCB Rule
    Select the treatment of any QE exceeding the contribution base.
    • Pay excess to Taxable Income.
    • Cap payments at MCB.
    • Ignore MCB.
      MCB rules only apply to percent-based allowance plans. Amount-based plans contribute to the quarterly MCB, but Workday doesn't apply the rule to amount-based earnings exceeding the contribution limit.
    Default
    Mark the final row of the grid as Default.
    Workday uses the default if no other restrictions apply to the worker.
    Restriction
    Use an existing restriction, or create a new one to define which workers this configuration applies to.
A group of workers in your organization have rules from a prior agreement that are different from your default method of treating earnings over the MCB. You can use superannuation configuration restriction rules to identify these workers and apply different MCB rules in the pay calculation.
