Do I need to show Foreign Remittance in ITR?

No. Its not any inward remittance or income. Where will you declare it in ITR?

It is  personal expenditure & will reflect in your capital account.

No need at all. Just combine with the rest of your personal expenses and list the total as a reduction from your capital account.

Just remember to claim credit for TCS if it's been deducted.

Sir, my boss has paid more than 40 lakh through the LRS Scheme, So where have to show in ITR
