Wealth tax is a direct tax levied on individuals, HUFs and companies annually. It is charged at the rate of 1% of net wealth (the value of specified assets on the valuation date in excess of the value of the debt that the taxpayer owes on the said assets) of a person if it exceeds Rs 30 lakh. Wealth tax is applicable on an asset held by a taxpayer as on March 31. Hence, the assets sold during the year are not subject to wealth tax.This tax is levied on the non-productive assets of a taxpayer. The intent of this law is to tax assets that do not generate any income.
