We enabled section 89 relief for employees but there are differences in manually calculated values and values coming from system. Mostly the difference is in /650 and what we calculate (Tax of previous years for income + arrears). We checked but it isn't case of recalculation of exemptions. Can anyone please help in the matter? What can be possible causes of this? Also, what is the relevance of /6i2 in calculation of /6i6? What is /6i2 exactly? Willing to provide screenshots if anyone needs more data. Thanks.
