Respected Sir,
At my office ,every month a same amount as TDS is deducted in each month salary.I got a SMS from IT Dept.,shows only amount of two months TDS amount.Hence I downloaded 26AS ,it also shows TDS deducted for two months instead of six months.
What is solution to have all six months TDS deducted to show on 26AS.Thanks in advance
