Wealth-tax rate structure revised: progressive banding and separate scales adjust individual and HUF tax computation. Amendment substitutes Part I of Schedule I to the Wealth-tax Act effective 1 April 1986, revising wealth-tax rates and thresholds. It prescribes progressive net-wealth bands for individuals (and most HUFs) with nil and graduated marginal-rate bands tied to successive thresholds, applying base amounts plus marginal percentages for higher brackets. A separate parallel scale applies to Hindu undivided families with at least one member exceeding the initial threshold, establishing a lower nil threshold and its own graduated bands and marginal rates for computing tax liability.
