My view is that such ITC can still be claimed and bar on ITC u/s 17 (5) (g) will not apply when such residential dwelling is used by an employees for his own home-accommodations. Some of reasoning for the same is as follows:
A. Prior to 01.02.2019, ITC was specifically disallowed as per then prevalent Section 17 (5) (b) which reads as follows:
"(b) the following supply of goods or services or both:-
(i) food and beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery except where an inward supply of goods or services or both of a particular category is used by a registered person for making an outward taxable supply of the same category of goods or services or both or as an element of a taxable composite or mixed supply;
(ii) membership of a club, health and fitness centre;
(iii) rent-a-cab, life insurance and health insuranceexcept where ––
(A) the Government notifies the services which are obligatory for an employer to provide to its employees under any law for the time being in force; or
(B) such inward supply of goods or services or both of a particular category is used by a registered person for making an outward taxable supply of the same category of goods or services or both or as part of a taxable composite or mixed supply; and
(iv) travel benefits extended to employees on vacation such as leave or home travel concession;"
B. The way I see this is that prior to 01.02.2019, to deny ITC against any inward supply - which is used for personal consumption by an employee - there were TWO specific situations:
I) ITC was denied on some specified inward-supplies (such as 'food and beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery) used by employees provided that 'the Government has NOT notified such services as obligatory for an employer to provide to its employees under any law for the time being in force'.
II) ITC was denied on travel benefits extended to employees on vacation such as leave or home travel concession, whether or NOT the Government notifies these services which are obligatory for an employer to provide to its employees under any law for the time being in force. This was blanket exclusion prior to 01.02.2019.
C. So, prior to 01.02.2019, there were TWO specific situations specified under same sub-section 17 (5) for any inward supply where 'personal consumption by an employee is the main angle to deny ITC' and one of those situations was blanket exclusion from ITC specifically dealing with supplies related to "travel benefits extended to employees on vacation" (which is as much a personal consumption by an employee and IF NOT MORE, as the issue under consideration). Hence, Section 17 (5) (g) should not be read into as dealing with a case of "personal consumption by an employee". Said restriction is only for "personal consumption by tax-payer assessee IMHO".
C1. In other words, if Section 17 (5) (g) also covers "personal consumption by an employee" to deny ITC, there was no need to put clause (iv) (i.e. travel benefits extended to employees on vacation such as leave or home travel concession) in Section 17 (5) (b).
D. Post 01.02.2019, main changes (in the context of this discussion) in above-said Section 17 (5) (b) was that ITC against every inward supplies specified therein is allowed if it is obligatory for an employer to provide the same to its employees under any law for the time being in force.
E. But, again, that also means that ITC against 'all specified inward supplies u/s 17 (5) (b)' will not be available when employer provides them to employees without any statutory obligation under law. And those specified inward supplies u/s 17 (5) (b) does not include 'Renting of Residential Dwelling Services' but continues to include "travel benefits extended to employees on vacation" and "Renting or hiring of Motor Vehicle".
F. Above arguments needs to be supported by demonstrating the facts to prove that such 'residential dwelling' fulfills other business-needs such as getting most-suitable employees who are not having own home in either in same city or in the vicinity of tax-payer's place of businesses where such employee is working etc. In other words, these services can be seen as 'personal consumption' from point of view of an employee but they are are not 'personal consumption' from point of view of the tax-paper assessee.
Hence, my view is that ITC against 'Renting of residential dwelling is used by an employee for his own home-accommodation' can still be claimed and bar on ITC u/s 17 (5) (g) will not apply.
These are ex facie views of mine and the same should not be construed as professional advice / suggestion.
