FAQs
Can Indian residents buy Rallybio stock?
Yes. Rallybio (RLYB) has been listed on NASDAQ since 2021, in the Biotechnology industry, and Indian residents can buy it through Paasa. You fund the account from your Indian bank under the RBI's Liberalised Remittance Scheme and the money is converted to US dollars. Shares are held in your own name at Interactive Brokers LLC and are SIPC-insured up to $500,000 in total, including $250,000 for cash.
How much does one Rallybio share cost in rupees?
One Rallybio share is $16.62 — about ₹1,596 at a USD/INR rate of 96.02 on 24 Sep 2026. Both the Rallybio price and the rupee rate move during the day, so the rupee cost changes with them.
What are the LRS and TCS rules for buying Rallybio from India?
Remit up to $250,000 per financial year under the RBI's Liberalised Remittance Scheme (LRS). Banks collect 20% tax at source on LRS remittances above ₹10 lakh in a financial year; the TCS is adjustable against your income-tax liability. FX and the LRS declaration are handled by your bank when you fund your account.
Can I buy whole shares of Rallybio?
Yes. One Rallybio share is $16.62, and you can buy as many whole shares as you like. You can also buy by amount rather than by quantity: there is no minimum trade size, and Paasa supports fractional investing in Rallybio.
How are gains on Rallybio 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 Rallybio price. Paasa issues a capital-gains statement for your return.
Does Rallybio pay a dividend?
No. Rallybio 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 Rallybio 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 Rallybio 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 Rallybio 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 Rallybio holding, its cost and its closing value.
How do I sell Rallybio 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.
