This feature is available when the National Pension, Health Insurance, and Employment Insurance settings are configured as Monthly Corporation Notice Amount. Please check your deduction item settings before using this feature.
When downloading a health insurance corporation notice file due to reasons such as a delayed acquisition report or a monthly remuneration change, the previous year's settlement amount may be included. If you reflect the previous year's settlement amount as-is without correcting it, the insurance premium attributed to the previous year will be recorded as the current year's insurance premium, which may result in an incorrect settlement amount!
This guide will walk you through how to handle the health insurance previous year settlement amount in flex.

How to Upload After Excluding the Previous Year Settlement Amount

Enter the amount attributable to the previous year in the year-end tax settlement item

Update the [Start Month] and [End Month] to the current year's dates, not the previous year's.
Example) When the 2024 notice file includes an amount from 2023
[If 100,000 KRW out of a 150,000 KRW settlement amount corresponds to the previous year]
Enter 100,000 KRW in the year-end tax settlement item
Correct the settlement amount to 50,000 KRW, deducting the year-end tax settlement amount.
