Instructions

Step 1: Create a deduction code

1. Search for Create Deduction.

   

2. Select a Name, Code, and Effective Date.

   1. Set the Effective Date on or before the earliest period you'll calculate.

      

3. Set the eligibility fields:

   1. Set Run Category Eligibility to Regular.

   2. Set Worker Eligibility to Payroll Input (Onetime or Ongoing) Exists for Pay Component (Sub Period).

      

Step 2: Set a calculation

Workday requires every deduction to have an associated calculation.

1. Select Payroll Input and check Input Amount Allowed?

   

Step 3: Set tax treatment

1. Navigate to Non-Effective Dated → Groups.

2. Add the deduction to groups based on how it should be taxed:

   • Post-tax — This is the default. A deduction is post-tax unless it's in a taxable reduction group. You can optionally add it to the Workday-delivered Post Tax Deductions group for net pay accumulation and payslip grouping.

     

   • Pre-tax — Add the deduction to the taxable reduction group for each tax it should be excluded from, such as Federal Taxable Reduction, State Withholding Taxable Reduction, FICA Taxable Reduction, or Section 125 Cafeteria Plan (for a cafeteria plan premium). Confirm the right groups with your payroll or benefits team.

     

Step 4: Create a new payroll input batch

A Payroll Input Batch is a shared label you attach to a group of submitted payroll inputs so Workday can track, report on, and clean them up together.

1. Search for Payroll Input by Batch ID.

2. Click Create Batch ID.

   

3. Enter a Batch_ID and Usage category.

   

4. Click OK.
