Vipin and others,
Just for sake of an argument, we may explore a possible argument.
What if we say that mother is only the legal owner of the property and the son is the actual/ beneficial owner of the property. The beneficial ownership plays an important role in determing the liability of paying capital gains in several circumstances.
The facts looked into for establishing beneficial ownership are normally as under:
The formal owner is not a benefical owner he/she:
• Acts as a conduit for another person who actually receives the benefit of dividends; or
• Is a mere fiduciary or administrator acting on behalf of the interested persons
Now in this case it can be argued that the mother is only a conduit for the son.
Thus if the son is the beneficial owner of the capital asset, the income generated from it should also be attributed to the son. The fact that son is paying back the housing loan and the interest can further strengthen the case. Consequently, the benefits of deduction under 24B and 80C should be allowed to the son.
But there is a flip side. If the above argument is made, then an alternative accusation can be made that the beneficial owner used his mother to avoid stamp duty. Accordingly, the consequence of avoidance of stamp duty should be attributed to the son.
Also, if the beneficial ownership argument is forwarded, then the son shall also be liable for paying taxes on the rent income (if, any) and possible future tax liability on LTCG (if any may arise on sale of the impugned property)
As I said before, I normally don't like such playing around with the facts. Though there is no harm in taking an aggresive tax position provided the above mentioned negatives can be factored in.
