A friend of mine has realized huge capital gains after a decade. Note, he has been filing nil / negligible returns over the past years and now has to pay capital gain tax in lakhs. He has to pay it via NEFT/RTGS method since it's not trivial.
Will it be safe to do so via NEFT/RTGS?
Also, I believe there is no requirement for any audit since it's his individual income and not any business income. Please confirm.
