Silly question to which I should know the answer but having a brain fatigue moment
Client with small property portfolio. In 2012/13 a commercial property was sold giviunbg rise to a drop in income drom lettings for the year. The shop was sold together with the flat above which was clients PPR. We are still waiting for info from client's agent (RICS) as to split in sale price between shop and flat so any CGT cannot yet be determined.
In looking at whether client should request reduction in payments on account because of fall in income, should any potential CGT be taken into account?
