Indian residents can buy Retension Pharmaceuticals shares through Paasa in four steps. Funds leave India under the RBI's Liberalised Remittance Scheme and the shares are held in your own name with Interactive Brokers. Read the full guide: how to invest in Retension Pharmaceuticals from India

  1. Open a Paasa account

    Complete digital KYC with your PAN, Aadhaar and address proof. Your brokerage account is opened in your own name with Interactive Brokers.

  3. Search for Retension Pharmaceuticals and place an order

    Find Retension Pharmaceuticals by name or by its ticker, RTSN, and choose an order type. You can buy by amount or by quantity — fractional shares mean there is no minimum trade size. Retension Pharmaceuticals trades 7:00 pm – 1:30 am IST; orders can only execute during that window.

FAQs

Can Indian residents buy Retension Pharmaceuticals stock?

Yes. Retension Pharmaceuticals (RTSN) has been listed on NASDAQ since 2026, in the Medical - Pharmaceuticals 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 Retension Pharmaceuticals share cost in rupees?

One Retension Pharmaceuticals share is $10.53 — about ₹1,020 at a USD/INR rate of 96.87 on 9 Oct 2026. Both the Retension Pharmaceuticals 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 Retension Pharmaceuticals 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 Retension Pharmaceuticals?

Yes. One Retension Pharmaceuticals share is $10.53, 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 Retension Pharmaceuticals.

How are gains on Retension Pharmaceuticals 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 Retension Pharmaceuticals price. Paasa issues a capital-gains statement for your return.

Does Retension Pharmaceuticals pay a dividend?

No. Retension Pharmaceuticals 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 Retension Pharmaceuticals 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 Retension Pharmaceuticals 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 Retension Pharmaceuticals 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 Retension Pharmaceuticals holding, its cost and its closing value.

How do I sell Retension Pharmaceuticals 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.
