How to buy Serina Therapeutics from India

Indian residents can buy Serina Therapeutics 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.

  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.

  2. Add funds under LRS

    Transfer INR from your Indian bank account. Your bank reports the remittance under the RBI's Liberalised Remittance Scheme and converts it to US dollars.

  3. Search for Serina Therapeutics and place an order

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

  4. Track holdings and download tax reports

    Follow your Serina Therapeutics position in USD and INR. Serina Therapeutics pays no dividend today, so your filing is the capital-gains statement plus the Schedule FA holding line.

FAQs

Can Indian residents buy Serina Therapeutics stock?

Yes. Serina Therapeutics (SER) has been listed on NYSE American since 2018, 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 Serina Therapeutics share cost in rupees?

One Serina Therapeutics share is $2.08 — about ₹200 at a USD/INR rate of 96.06 on 29 Sep 2026. Both the Serina Therapeutics 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 Serina Therapeutics 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 Serina Therapeutics?

Yes. One Serina Therapeutics share is $2.08, 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 Serina Therapeutics.

How are gains on Serina Therapeutics 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 Serina Therapeutics price. Paasa issues a capital-gains statement for your return.

Does Serina Therapeutics pay a dividend?

No. Serina Therapeutics 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 Serina Therapeutics from India?

NYSE American 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 Serina Therapeutics 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 Serina Therapeutics 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 Serina Therapeutics holding, its cost and its closing value.

How do I sell Serina Therapeutics 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.
