One of my friend is a Pensioner and is also running a proprietory business for the past three years. For the past 2 years, he has filed ITR 4. This year, ( FY - 22 23 ) he has sold a property and has incurred long term Capital gain.
Now, can he file his IT return in Form ITR 3 for this FY ?
If yes, can he revert back to ITR 4 in the subsequent years ?
