if the proprietor of organisation expire, can authorize signatory pay the tax with his/her name?

Hello All,
Here is an organisation which proprietor expired but authorize signatory deposit the tax like tds and income tax under the name of proprietor who is no more with out mentioning the word “Late” before the name of proprietor.
In this case, is it legally right or wrong?
If it is wrong, tell me correct procedure, athough they already sent the death information of proprietor to Department of Income tax office.
