142.This section provides the time limits under which a Revenue Scotland assessment may be made. The general time limit for the making of a Revenue Scotland assessment is five years from the “relevant date”. This time limit is extended to 20 years where the loss of tax is attributable to deliberate behaviour by the taxpayer or a “related person”. A Revenue Scotland assessment to recover excessive repayment of tax is not late if it is made within 12 months of that repayment. If a taxpayer has died, a Revenue Scotland assessment may be made on a taxpayer’s personal representatives within three years of death and is limited to “relevant dates” within five years before the death. It also sets out how any objection to a Revenue Scotland assessment on the basis of the time limits can be made and defines “relevant date” and “related person”.
