There are numerous slabs and sections under which you can save on tax if you reinvest your long-term capital gains (In your case, it is capital loss- there is no need to reinvest the amount):
Section 54: Under this section, you can avoid tax on capital gains from the sale of a house property if you reinvest the money to buy another property. You can claim tax exemptions under this section if you buy the new property one year before the sale or two years after the sale. In case it is under construction, the new property should be ready within three years of the old property’s sale.
Section 54EC: You can claim tax exemption by using the amount you gain from selling an asset to buy bonds issued by NHAI and REC.The bonds should be bought within 6 months of the sale of the asset. The maximum amount you can invest in this way is Rs. 50 lakh. It will lock your money for 5 years.
Section 54F: You can claim total tax exemption by using the money you gain from selling any asset (except a house property) to buy a house property, which needs to be bought one year before the sale or two years after thse sale. For under-construction properties, the new property should be ready within three years of the asset’s sale.
Capital Gains Account Scheme (CAGS): if you do not get a chance to invest in a profitable property immediately and still want to save your long-term gains from being taxed, you can invest your capital gains in CGDAS by approaching any public sector bank. The timeframe for the purchase or construction of the property remains unchanged in this case as well. But you can utilise this account momentarily so that you save your gains from being taxed and have more time to finalise a property for reinvestment.
It is required to deposit such unutilised capital gain in the capital gains account before furnishing return of income but not beyond due date for furnishing return of income.
Normally, the due date of filing Income Tax return is July 31 for the previous Financial Year. Under extraordinary circumstances, it can be extended by the Finance Ministry.
This is just for your information.
