Net Pay and Arrears Processing Calculations

Initial gross-to-net calculation
To adjust net pay during payroll processing, Workday first performs an initial gross-to-net calculation (excluding arrears amounts) to verify that an employee's net pay is at, or above, the net pay minimum (zero by default).
Example:
Deduction
Current Period Amount
Arrears Amount
A
100
50
B
50
25
C
25
10
When calculating net pay, Workday deducts only the current period values of deductions A, B, and C (100 + 50 + 25), not the arrears amounts.
Subsequent calculations when initial net pay is above the minimum
For employees with positive net pay (net pay > minimum net) and no arrears, there are no subsequent calculations. The initial calculation is used.
For employees with positive net pay (net pay > minimum net) and outstanding arrears, Workday:
  • Recoups the arrears based on the deduction priorities defined by the
    Maintain Deduction Priorities
    task (subject to applicable arrears limits).
  • Performs multiple iterations to reduce pretax deduction arrears. After each loop, Workday modifies the applicable deduction (based on priority) by adding the positive net value to the deduction value and redetermining net pay. Once 2 loops produce the same net value, the iterations stop.
  • Generates new gross-to-net results.
Example
: Eric had medical benefits deducted while he was on leave. When he returns, you need to recoup as much as possible from his pay.
To recoup arrears, Workday determines the most current outstanding arrears balance by referencing the last completed payroll result that has a payment date earlier than the current payroll result.
Subsequent calculations when initial net pay is below the minimum
For employees with negative net pay (net pay < minimum net) and outstanding arrears, Workday:
  • Reduces or eliminates deductions based on the deduction priorities defined by the
    Maintain Deduction Priorities
    task and puts them into arrears.
  • Recalculates taxes, if the net pay validation forces the reduction or elimination of pretax deductions (from the
    Pre Tax Deduction
    pay component group).
  • If Workday recalculated taxes and took a partial amount for a pretax deduction, it adds the negative net value to the deduction until net pay reaches the minimum net amount, produces the same net value in 2 loops, or completes 50 loops and then places the pretax deduction into arrears.
  • Generates new gross-to-net results.
Restrictions
The
Run Retro Pay Calculation
task doesn't put deductions into arrears or attempt to recoup arrears generated for a completed pay calculation.
When you run retro for a period with a deduction in arrears, Workday sometimes calculates a negative retro result for the impacted deduction. To avoid issuing a retro refund for the deduction not taken, Workday first recoups the arrears balance for the deduction with negative retro amount, then recoups the arrears balances for current period and historical deductions.
For Payroll for the U.S., Workday doesn’t split arrears deductions for workers with multiple tax authority worktags.

Arrears Reporting

Workday provides these reports for tracking arrears balances and managing arrears processing rules:
  • The
    Pay Calculation Results - Outstanding Arrears Balance Composite
    report (secured to the
    Reports: Pay Calculation Results (Reports: Indexed Data Source Filters)
    domain) displays arrears balances in a given pay period for workers in 1 or more pay run groups or pay groups.
  • The
    Net Pay Validation and Arrears Rules
    and
    Net Pay Validation and Arrears Rules (filter by priority)
    reports (secured to the
    Set Up: Payroll (Calculations - Payroll Specific)
    domain) display net pay validation and arrears processing rules for all deductions in Workday.
  • The
    Most Recent Arrears Transaction for Worker
    report field (secured to the
    Reports: Results for Worker (Pay Calculation)
    domain) on the Worker business object enables you to generate custom reports to view 1 or more workers when there is at least 1 worker with deductions in arrears or at least 1 deduction in common.
