Where the income tax chargeable has been under-assessed or where such income has been assessed at too low a rate or where excessive relief is granted to the non-resident Indian, the Assessing Officer may reassess such income or re-compute the loss for the assessment year concerned. Where the Assessing Officer believes that such assessment or re-assessment is due to the omission or failure on the part of the Non-Resident Indian to disclose fully and truly all facts in the return, the Assessing Officer can issue a notice under Section 148/147(a) within 4, or 6 years, depending on the quantum of income concerned. |
