How to buy Aton from India

Indian residents can buy Aton 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 and then to EUR.

  3. Search for Aton and place an order

    Find Aton by name or by its ticker, ALTAO, and choose an order type. Aton trades 12:30 pm – 9:00 pm IST; orders can only execute during that window.

  4. Track holdings and download tax reports

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

FAQs

Can Indian residents buy Aton stock?

Yes. Aton (ALTAO) has been listed on Euronext Paris since 2007, 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 and then to EUR. Shares are held in your own name at Interactive Brokers, segregated from Paasa's own assets.

How much does one Aton share cost in rupees?

One Aton share is €0.01 — about ₹1 at an EUR/INR rate of 109.37 on 25 Sep 2026. Both the Aton 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 Aton 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.

How are gains on Aton shares taxed in India?

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 EUR/INR rate on the purchase and the sale date, so the rupee move counts alongside the Aton price. Paasa issues a capital-gains statement for your return.

Does Aton pay a dividend?

No. Aton 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 Aton from India?

Euronext Paris trades 12:30 pm – 9:00 pm IST in Indian time. The window shifts to 1:30 pm – 10:00 pm IST when France is on standard time. Orders can only execute during that window.

Do I have to declare Aton 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 Aton holding, its cost and its closing value.

How do I sell Aton and bring the money back to India?

You sell during market hours (12:30 pm – 9:00 pm IST) and the proceeds settle in EUR 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.

Does the rupee rate affect what I make on Aton?

Yes. Aton is priced in EUR, so your rupee outcome combines the EUR move with the EUR/INR move between the day you remit and the day you convert back. Both directions are reflected in the capital-gains statement Paasa issues.
