The liability of quoting wrong PAN of the deductee, in TDS return is imposed on the Assessee filing the TDS return and not on the deductee unless he has given the wrong PAN in writing.
How to check that PAN given is correct or not:
I am suggesting a WAY to check:
SELECT challan 280
Fill the correct PAN no. and other fake details like in name field type "a" etc...
select any bank, advance tax, latest assessment year etc.
click to accept the data
THE SYSTEM WILL SHOW THE NAME OF PAN HOLDER IN RED COLOUR
