Hello taxpayer,
Going by the limited facts of your query, I have understood that you are having income from salary and trading of crytocurrencies and you are falling within high income tax bracket.
Second, gains from crypto trading can either be classified as business income or capital gains depending on a wide range of parameters which are not clear from above query. Please note that the govt may discard any beneficial position that you try to take without strong reasoning and documentation in this regard.
Third, any income tax charge arising on a income where either TDS/WHT has been deducted needs to be deposited by way of quarterly advance tax installments during the year to avoid penal interest at the time of return filing.
Fourth, being in HNI category you need to comply with a wide set of additional compliances and pay surcharge along with normal income tax & cess. The exact tax rate will depend on total income that is finally computed and its composition.
Given the multiple aspects of your query and significant implications of the same, it is advisable to have a telephonic consultation for detailed discussion on end to end tax planning along with possible exemption claims.
Best Regards,
