The new decision to fix the taxation undue tax loss came into effect on 1^st January 2016. If a tax payer has not paid his or her taxes by the recommended time, or the tax inspector has accumulated more taxes than recommended (irrespective of the tax payer), the undue loss will be set as 0.0537% per each day.

In order to calculate the undue loss, the average tugrik loan rate of the commercial banks has been taken into consideration. As of November 2015, the average tugrik loan rate was annually 19.6%; monthly 1.63% and 0.0537% daily.
