1. Introduction
In the year-end adjustment procedure from October 2020, employees are able to submit electronic data for applying deductions, replacing the attachment of paper documents on applications such as the “Application for Deduction for Insurance Premiums for Employment Income Earner” and the “Application for Deduction for Special Credit for Loans, etc. Related to a Dwelling (Specific Additions or Improvements, etc.).”

The introduction of electronic submission of documents will mitigate the year-end adjustment paperwork which used to be complex and troublesome for both companies and employees. In this News, we will mention the summary of digitization in the year-end adjustment procedure.

2. Advantages of digitization
Digitization in the year-end adjustment procedure will be beneficial not only to administrators in companies but also to employees from the reasons below.

      In cases where employees use the software for the year-end adjustment known as “Nencho-Software,” it will calculate the amount of deductions for insurance premiums and others automatically; hence, companies will no longer be required to double-check employees’ calculations.
・Increased accuracy
      In cases where employees use electronic certificates for insurance premiums deductions, companies will no longer be required to check the amount of deductions with the original documents.
