You are getting a monthly amount of 20000 and yearly perquisite of 140000 which means total amount is 380000.
Why are you getting rent as well as perquisites?
Perquisites are provided if your employer is providing you some property or taking some property on lease for you.
Perquisite amount taxable would be for unfurnished flat:
Rent paid or 15% of salary whichever is lower less rent recovered from you.
Since you are owning house yourself i dont think you will get any benefit.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you.
