An inheritance tax charge made every ten years on most forms of discretionary trust (now defined as relevant property trusts). As a discretionary trust does not attach to the life of an individual there is no inheritance-tax charge on passing through the generations. To compensate for this a ten-year charge, calculated at 30% of the lifetime rate, is assessed, so that a full charge is made every 33.33 years. Assets are valued at market value at the tenth anniversary of the trust after 31 March 1984, and every ten years thereafter. The current rate is 6%, being 30% of the current lifetime rate of 20%.
