136.This section provides that, where a person makes a tax return after Revenue Scotland has made a determination of chargeable tax, the self-assessed tax return will supersede Revenue Scotland’s determination. This provision does not apply when a person makes a tax return more than five years after the power to make the determination was first exercisable by Revenue Scotland, or more than three months after the date on which the determination was issued, whichever is the later. In instances where proceedings have commenced for the recovery of tax following a Revenue Scotland determination, and during those proceedings Revenue Scotland receives a self-assessment that supersedes its determination, the proceedings may continue as if they were for the recovery of so much of the self-assessed tax which remains due and not yet paid.
