Section 80GG allows individuals a deduction for rent paid for furnished or unfurnished accommodation. 

The deduction is allowed to taxpayers who do not receive any HRA (House Rent Allowance) from their employer.

So if you are unable to see the deduction entered under this section, then it means you have already added the HRA received under salary income and hence you are not eligible to claim this deduction.

How is deduction u/s 80GG calculated?

The deduction under Section 80GG is given to the least of the following :

  1. Total rent paid minus 10% of basic salary.
  2. Rs 60,000 per year (Rs 5,000 per month).
  3. 25% of the adjusted gross total income.
