Special Allowance Is Less Than Previous Month

Hi,
My special allowance included in my payslip for the month of April 2017 is less than March 2017. I've declared investments under section 80C which has reduced my TDS but I don't understand the reason behind the difference in special allowance.
Need inputs from experts here before I go and talk to the HR.
Thanks,
Abhik.

Dear Abhik
Without knowing the basis on which the Spl.Allowance is computed how one can comment. Give details. Give full components of CTC to examine. When is your appraisal and increment due ?

Please do not club TDS with less Special Allowance.As already pointed by Mr Kumar, furnish relevant details to know any injustice has been done to you.What do you mean by difference? is it short payment

Your HR can only guide you with reason of lesser Spl. Allowance than the previous month. If there is any LWP it should effect every component of your Salary and not only one component. Apart from that if there is any recovery it should feature seperately in the Deductions and not adjusted in any Salary component to the best of my view

1. Check your attendance for April, if it is equivalent then check with HR. Simply ask them to explain as to why it is less than the last month? You have not mentioned comparison of February with March, are they same?

Thank you for the replies.
I checked with the HR. Actually, I had increased my declarations under Flexible Benefit Plans like Telephone and Medical Allowances which is being adjusted from Special Allowance. The same will be paid every month once I submit the respective bills or in March 2018 after necessary deductions.
Actually, I had made a mistake here as I wasn't much aware. I was planning to invest some amount in SIP and had declared accordingly under 80C, this has redcued my TDS compared to months in last FY. But now since certain amount is going to FBP, I'm not able to use the money which I'm saving in tax. Hopefully, I've to wait every month once I submit the bills or till next March to get the lump sum amount.
Thanks.
