I own a buy-to-let (BTL) in Bradford and I want to transfer a share of 25% to my son so that he is a beneficial owner and gets part of the rental income. Does that lead to capital gains tax (CGT) for me? And will my son have to pay stamp duty land tax (SDLT)? 

Arthur Weller replies:  

It does lead to CGT for you if the property is worth more today than when you originally acquired it. But it appears that you are gifting the 25% of the property, i.e., for no consideration. If so, there should be no SDLT for your son to pay, if there is no existing debt on the property (e.g., a BTL mortgage).
