Capital gain tax expenditure

Can i claim as expenditure if i've put in a new bathroom and kitchen before selling

Hi
You can claim for the cost of improvements you have made to the property since you became the property owner. Improvements are permanent changes that raise the value of a property, like adding extensions or garages. Normal maintainance costs can not be claimed. In this example replacing a basic kitchen or bathrom with a luxury version would normally be considered an improvement. However, replacing them with something of a similar standard is not normally considered an improvement. 

if i own a 50% share in a property but gift my share, do i pay CGT on the 50% (difference in cost and present value)

Hi
Possibly if it is not your main home and not being gifted to a spouse or charity - Capital Gains Tax: what you pay it on, rates and allowances
