If a salary increment is approved after a payrun has already been processed — with an effective date that falls in a past pay period — you can use the Salary Backpay feature to automatically calculate and include the owed difference in your next payrun.
Feature Availability — Salary Backpay is controlled by a feature flag and may not be enabled on your account by default. Please contact JustLogin Support to request activation. |
How Salary Backpay Works
When a backdated salary increment is entered, the system detects that the effective date covers a period that has already been paid. Upon confirmation, it automatically calculates the backpay amount and creates a dedicated pay element under the employee's pay details, ready to be included in the next payrun.
Step 1: Enter the Backdated Salary Increment
- Navigate to Payroll → Administration → Salary Progression.
- Click View on the relevant employee.
- Enter the following details:
- Effective Date: Set this to the start month of the increment (the backdated date).
- New Basic Pay Amount: Enter the updated salary figure.
- Click Add.
- A confirmation prompt will appear asking whether to proceed with the backpay calculation. Click Yes to allow the system to automatically generate the backpay amount.
Step 2: Verify the Auto-Created Pay Element
After confirming, the system automatically creates a pay element to hold the backpay amount. You can find it here:
- Location: Employee Pay Details → Addition
- Pay Element Name:
Basic Pay - Back (Sys)
Step 3: Configure the Pay Element (Required for AW Classification)
To ensure the backpay pay element is correctly classified as Additional Wages (AW), update its configuration before processing payroll:
- Navigate to Configuration → Pay Element.
- Locate the
Basic Pay - Back (Sys)pay element. - Update the following settings:
- Wage Type: Set to AW (Additional Wages).
- Frequency: Set to One Time.
- Save your changes.
Step 4: Process Payroll
Once the pay element is configured, proceed with payroll processing as normal. The system will automatically calculate and include the backpay amount in the payrun — no manual entry is required.
