Why Some additional amount is not reflected in the iras?
The additions which are not taxable won't appear in IRAS.
Kindly select the additions taxable "yes" when those additions are subjected to the TAXABLE income.
Admin >> Manage Setting >> Edit the Addition >> Select Attract Taxable Gross = yes and the correct tax group
This will ensure that the additions subject to taxable income are properly reflected in the IRAS.
