My take:
A. Gifts (i.e. supply of goods / services / both without consideration) exceeding fifty thousand rupees in value in a financial year by an employer to an employee shall be treated as supply of goods or services or both, in view of serial No. 2 of Schedule - I read with Section 7 of the CGST Act, 2017.
B. ITC is not available against "goods" (here, there is no mention of services) which are disposed of by way of gift, in view of Section 17 (5) (h).
C. While both of above legal provisions are crystal clear, it does NOT mean, in my humble view, that tax-payer needs to do BOTH i.e. pay taxes against gifts (goods) to employee as 'outward supply' in view of serial No. 2 of Schedule - I read with Section 7 of the CGST Act, 2017as well as not to take ITC against very same goods in view of Section 17 (5) (h).
C1. The way, I read these two legal provisions, in my view, payment of taxes against gifts (goods) to employee as 'outward supply' in view of serial No. 2 of Schedule - I read with Section 7 of the CGST Act, 2017itself means 'reversal of ITC' - fulfilling the requirement of Section 17 (5) (h) - simultaneously.
C2. This is more so because employee will not take ITC against outward tax so charged & paid by the employer. Furthermore, being related party transaction without consideration, value of outward supply will be market price (i.e. purchase price, generally specking) resulting into outward tax liability equal to ITC claimed against goods (i.e. gifts) involved.
C3. In other words, there can NOT be double loss (i.e. payment of outward tax as well as loss of ITC) to the tax-payer / employer against gifts given to his employees in subject situation under discussion here because payment of outward tax by itself fulfils both requirements of law.
These are ex facie views of mine and the same should not be construed as professional advice / suggestion.
