Re: Trading up - any capital gains liability ??
1. Have you ever rented out the property, other than under the Rent a Room Scheme?
2. Have you occupied the house as your main residence for the last 4 years, excluding the past 12 months?
If the answer to (1) is 'No' and the answer to (2) is 'Yes', then you will have NO tax on sale of your property.
