Long Term Capital Loss

The assessee has loss (other than shares) under the head of Long Term Capital Gain.The assessee does not want to set off in the same year nor does he want to carry forward it.The assessee has taxable income and he want to file his Return Of Income.Whether it is necessary to show calculation of loss under the head Capital Gain in his Return Of Income eventhough he does not want to set off or carry forward the same even in future? Sec 50C is not applicable in this case because loss under the head of Capital Gain is of other than Shares and IMMOVABLE PROPERTIES.Please give reasons.
