Rent Free Accomodation by CG

employer is central government and providing rent Free Accomodation to employees.
CG (employer) doesn't own the house and therefore CG (employer) deducts TDS u/s 194-I on rent payment to landlord.

now the question is, whether this Rent free accomodation is taxable in the hands of employees? as CG (employer) has already deducted TDS on rent payment.

if yes, then isn't it attract double taxation on single rent income??
