Dear Querist
My opinion on your queries are as under:
1.Is giving false declaration to IT dept to escape a TDS fraud an offence or not?
Opinion: It is an offence, If a person or entity fails to deduct tax at source for payments made to a third party (for example prize money of lottery etc) or in another case, collects the tax at source but does not remit the same to the IT department, then he is liable to pay a penalty equal to amount of tax which was failed to be deducted at source.
2.Is the concerned ITO trying to save the tenant as it appears to me.
Opinion: It may be possible.
3.Is being a private partnership firm & an engineering educational institution with teaching/non teaching staff & faculty,not enough ground to have provisions of TDS applicable?
Opinion: TDS will be applicable on them being a third party transaction which was more then 20,000/-
4.What should be my reply to the ITO?(The ITO,infact,at the first instance,just accepted the false declaration of the tenant as an individual,never bothered to investigate & closed the case,till I brought the truth to notice,that the tenant is a regd. partnership firm)
Opinion: It's depend on the contents of the notice and requirement of department, is there any registered rent agreement executed between the tenant and your father?
