in NIC class 1 primary and secondary ,we reduce the threshold of 5715 and 43875 according to months…bt i am confused in NIC 4….do v also reduce the threshold in it????refer to que 1(b) of june 2011 paper…
Dont worry with NIC 4 about reducing threshold. Since NIC 4 is paid along with income tax due date i.e. 31 January, 31 July and balance in 31 january of next year. However first two installment are based on the last year profits. As we dont have to worry about apportioning the threshold on monthly basis.
I am not sure of question, however I do think I have solved your problem.
