Deduction from Net Annual Value (NAV)

Taxpayers should be aware that for every house property owned by them, income tax is payable on a yearly basis. The tax payable is calculated as a percentage of the net annual value of the property. The net annual value is determined based on the approximate amount of annual rent which the property can be expected to fetch in the market at an arms' length price. Each and every house property owned by a taxpayer is taxable, with the exclusive exception of self-occupied residential properties. Even in the case of self-occupied residential properties, the exemption from taxability is given only for one self-occupied property.  According to Section 24 of the Income Tax Act, “the Income from House Property shall be reduced by the amount of interest that is paid on Loan where the loan has been taken for the purpose of purchase, construction, renewal, repair or reconstruction of property”. The following deduction from Net Annual Value (NAV) is permissible to determine the taxable income from house property:
  • Deduction at 30% on NAV under Section 24(a).
  • Interest on loan under Section 24(b) if the loan is taken for purchases, construction, repair or reconstruction of House Property.

Self-occupied house property does not require standard deduction because there is no NAV for a self-occupied house.
