You did not provide enough information to determine taxability.
Most professional partnerships are purchased, with equity commitments, assumption of debts, a contract for services, termination, covenant not to compete, and other factors. You mentioned none.
If the interest in a partnership worth $250,000 is being transferred to you without consideration, that's very possibly taxable. Not enough information was provided.
i stand by my response. I said "but with the limited facts presented, you might have no tax due. " It very possible it could be taxable.
Since the advisor you consulted likely had more information on the transfer, and advised it was indeed taxable, then I tend to agree. You just didn't provide enough information.
I will advise site management to close out your request.
