True Sir, central government pensioners draw their pension through scheduled commercial banks. Banks can deduct the TDS if the annual pension exceeds the threshold limit of taxation. They cannot deduct any TDS unless the pension account holders intimate them about other sources of income viz Term Deposits etc. In any case a big chunk of senior citizens (even super senior citizens) get all benefits due to them but never bother to pay any income tax at all.
The context of my query is whether the concerned departments of Govt like CBDT, CPAO etc should build up a mechanism to check whether the additional payment of 20% of basic pension is to be allowed as a blanket to all 80+ pensioners or to warn them for first paying their dues before getting any additional payment etc
