When a taxpayer sells property, shares, or any capital asset, capital gain tax becomes applicable.
However, the Income Tax Act provides multiple exemptions which can legally reduce or eliminate tax, if planned correctly.
With the introduction of the Income Tax Act, 2025:
- Section numbers have been reorganized into 120 series
- Core provisions remain largely unchanged
- Focus now is on limits, timelines & structured compliance
