Stamp duty value governs stock-in-trade valuation, with safe harbour relief and agreement-date adoption where banking conditions are met. Determination of the full value of consideration for transfer of land or building held as stock-in-trade is governed by the stamp duty value mechanism. Where the consideration received or accrued is less than the stamp duty value, that value is treated as the full value of consideration for computing income under the head Profits and Gains of Business or Profession. If the date of agreement and the date of registration are different, and part of the consideration has been received on or before the agreement date through specified banking or electronic modes, the stamp duty value on the agreement date may be adopted instead of the registration-date value.
