Mismatch in form 16 and 26 as

Dear sir,

My form 16 shows that my taxable income is 532270 for year 2013-14 and tax deducted is 37548.

My form 26as shows total amount paid credited 554974 and tax deducted is 37548.

i donot have any other income source other than salary. e.g. no fixed deposits,shares etc.

what to do in this case.
