Tds credit as per form 26as

One of my client being a HUF having Commission Income,Consultancy Charges Income & Interest Income are main sources of Income.

I have filed online ITR-4 relevant to Asst.Year 2014-15 on 11.07.2014 with digital Signature.

Till the filing of return i have claimed TDS Credit in his return as per Form 26AS.

Moreover I have shown consultancy Income of Rs.173000/- on which TDS was not deducted by the deductor hence the same was not shown in 26AS also.

However after filing of said return the deductor has intimated to my client that a TDS of Rs.17300/- was deducted & deposited to Government by way of filing E-TDS return relevant to Last IVth Quarter pertaining to F.Y.2013-14 in Aug,2014.

Now the same is displaying in Form 26AS also.But i have not claimed the same in my ITR relevant to Asstt.Year 2014-15.

Now query is how to claim this Additional TDS Credit of Rs.17300/- in my clients Tax Return though i have already shown relevant income in Return. That is whether i have to file revised return to claim the said TDS Credit of Rs.17300/- or can i claim in next Asstt Year 2015-16 when i am going to file the return.

Please advice urgently
