Property sold to wife via power of attorney

It was better to execute a gift deed instead of sale deed. Anyways now you will pay the tax for the sale amount .

So I am a general power of attorney holder, will the tax liability comes on me ?

And if yes so what I can do purchase any other property of same amount?

You have mentioned in sale  deed that you received a consideration sum for sale of property and for that amount you have to pay tax.

If you want to show investment as capital gain then better you consult some tax consultant he will advise you better.

The facts posted lack clarity. What do you mean by "I purchased a home via power of attorney in 1988"?
