Hi
Have you only received a property as a gift? Or you have sold the gifted property? Tax is applicable only when the gifted property is sold.
1. No
2. No
3. If you are paying the amount of capital gains to your husband and getting a registration done for the co-ownership in the property, it would be considered as sale of property by your husband and a purchase by you. If such sale transaction happens within 2 years or sale of gifted property, capital gain tax shall be exempt.
Above all this, let us know whether the gifted property is sold or not. Also, capital gain calculations need to be done. Please provide the details of costs and sales consideration and respective dates of transfers.
