How are gains on Quantumsphere Acquisition Corp. Units shares taxed in India?

The US does not levy capital gains tax on shares for Indian residents, so the tax is an India-side one. Gains on shares held for more than 24 months are long-term and taxed at 12.5%. Gains on shares held for 24 months or less are short-term and taxed at your income-tax slab rate. The gain is computed in rupees using the USD/INR rate on the purchase and the sale date, so the rupee move counts alongside the Quantumsphere Acquisition Corp. Units price. Paasa issues a capital-gains statement for your return.

Does Quantumsphere Acquisition Corp. Units pay a dividend?

No. Quantumsphere Acquisition Corp. Units does not currently pay a dividend, so holding it produces no dividend income to declare in India. If it starts paying one, the Indian treatment is the usual one — dividends are taxed at your slab rate in India — and Paasa's dividend report would show the gross amount and any tax withheld.

When can I trade Quantumsphere Acquisition Corp. Units from India?

NASDAQ trades 7:00 pm – 1:30 am IST in Indian time, so the close lands after midnight. The window shifts to 8:00 pm – 2:30 am IST when the US is on standard time. Orders can only execute during that window.

Is there estate or inheritance tax on Quantumsphere Acquisition Corp. Units shares held from India?

US-situs assets such as US-listed shares can be exposed to US estate tax for non-US persons. It applies to your overall holdings in that jurisdiction rather than to any one position. Paasa's US estate tax calculator shows the exposure for a given portfolio value.

Do I have to declare Quantumsphere Acquisition Corp. Units shares in my Indian tax return?

Yes. Foreign shares held on 31 March must be reported in Schedule FA of your Indian income-tax return. Paasa gives you a Schedule FA-ready statement listing your Quantumsphere Acquisition Corp. Units holding, its cost and its closing value.

How do I sell Quantumsphere Acquisition Corp. Units and bring the money back to India?

You sell during market hours (7:00 pm – 1:30 am IST) and the proceeds settle in USD in your Paasa account. From there you can hold the balance, reinvest, or repatriate. Funds can be withdrawn in any currency to any bank account in your own name. Whether the sale is short- or long-term is decided by the 24-month holding period.
