Get due salary in next year

. if ITR of 2015-16 AY is not filled yet, then show this income in last year. otherwise you can take rebate u/s 89 in AY 2016-17

Is there any columns in ITR to show income of last month.
Actually situation is department is asking for my income,investment & all , so that they deduct calculated tax from salary of month Feb-15. So i am in dilema that will i show it in my income or not,
as it's income of last year.
 

you have to show this in your income. employer will deduct tax on your current income only. they will show balance tax amount as relife u/s 89. then you can claim this in return also
