Company Lease Accomodation

Sir, I am working in an IT company, where i get 20000-HRA. Since my landlord asked for doing agreement with the company, therefore I availed Company Lease accomodation option. I pay Rs 15000 as a rent paid by my company as a CLA, and on remaining HRA amount tax is deducted.

Now my query is the CLA of 15000X12=Rs 180000 is also taxable, as i found that my company has taken this amount as a taxable amount and deducted tax on it.

Pls advise.
