CGT on second property

My question is a calculation for PPR and capital gains I have owned a second property for 7 years and have rented it out during that period. I intend to sell my main residence and move into that property for two years and then sell it. What tax will I be liable to pay? And will the gain be added to my self assessment as a lump. I’m currently in the lower rate tax band and am sole director of my ltd company.

Hi Laura Free,
HMRC cannot comment on future events as legislation and/or plans may change.
Based on current guidance, you would be due private residence relief on the 2nd property for the 2 years you plan to live in it.
The rate of tax you pay depends on the gain made as it could be 18% or 24% 
Thank you.
