Are expenses on my primary residence for improvement and renovation tax deductible?

If you have renovated your property and improved its income earning capacity (for example, you have added on a room) then this would be regarded as capital expenditure - it would not be deducted from income, but would be added to the base cost of the property and used to decrease capital gains tax when you sell it one day.
