Income Earned outside India by a non resident is not taxable in India as long as the same is not received directly in your Indian bank account when your earned it. It is apparent from your question that the said amount is not received in India and you want to bring the same to India.

The principal amount when remitted to India will not be considered as income. In fact even the interest amount is also not considered as income at the time of remittance. Interest would be taxed in India the year of accrual depending on whether you were resident at the time of such accrual.

If you were resident at the time of accrual of interest but you have not disclosed this income in your Indian Income tax return, although above the taxable limit, then perhaps this will amount to black money and not otherwise.

Principal money represents savings from income taxed outside India and it is certainly not black money. Interest on money braught to India will be taxed when gross total income exceeds basic exemption limit under I T Act.
