Dear if the House or Building is used in business where depreciation is being claimed under Income Tax Act, then Indexation benefit will not be allowed and such assets are not eligible for Indexation.
Here we provide depreciation whereby we are charging off Depreciation to the Books of accounts and getting benefit of time value. Thus, whenever we sell this assets, it would be treated as either Short term Capital Gain or Loss.
Depreciation and Indexation benefits cant be claimed simultaneously. Indexation is allowed only for Long term Asset.
Thanks
