The year-end tax settlement preview is a service that allows wage earners to check their tax burden and expected refund amount in advance through the National Tax Service Hometax. This allows you to prevent deduction omissions and prepare in advance to avoid unnecessary tax burdens. The year-end tax settlement is usually conducted in January of the following year, but the preview service is provided between October and December, so be sure to use it.
