I don't know how to fill out the request form for switching to special collection.

For details on how to enter the “Request for Switching to Special Collection”, please refer to “D: Switching to Special Collection” on the “Submission of Transfer Notification / Change Request” page.
At that time, please attach a copy of the payment notice for the normal collection of the employee (taxpayer) during the switching period, a copy of the tax payment notice, and a copy of the receipt if there is a paid period.
In addition, the tax amount that has already passed the deadline (if the original delivery date has arrived if the payment has been made), cannot be switched to special collection.
In addition, the special collection start month should, in principle, be after the month following the month in which the switching request is submitted.
Download registration form, etc.
