ESA If you sell property, stock, or other assets that you&#8217;ve held for years at a time, then inflation erodes the actual worth of your investment. For the purposes of fair tax the legislation does allow the purchase price to be increase using the Cost Inflation Index (CII).&nbsp;<\/p>\n\n\n\n<p>This is known as indexation. Taxpayers can be helped by indexation to reduce their taxable capital gains and prevent paying tax on increases caused by inflation.

The legislated formula includes special rules on the valuation of older assets and on indexation, such as which is the fair market value of the asset at the time of purchase, at what point indexation is relevant (after 24 or 36 months holding) according to the type of asset held.<\/p>\n\n\n\n<div class=\"btn-div\">\n\n    <a href=\"https:\/\/me9.in\/MBB\" class=\"marg-btn\" target=\"_blank\" rel=\"noopener\">Get Cloud-Based GST Billing Software<\/a>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Indexed_Cost_of_Acquisition\"><\/span>What Is Indexed Cost of Acquisition?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Indices of Cost of Acquisition means the original price of purchase of an asset adjusted for inflation to be weighted by Cost Inflation Index (CII).
