Is a valuation required?
To calculate the gains or losses arising on the disposal you may need to provide a valuation. For example, a valuation at 5 April 2013 or 5 April 2015 or 5 April 2016. Where a valuation is required it must be the open market value of the property or interest in the property at the relevant date.
Please note: An estimated valuation for an Annual Tax on Enveloped Dwellings (ATED) pre-return banding check does not count as an agreed valuation for the purposes of calculating the amount of any ATED-related capital gain or loss. For further guidance follow the link below.
