FAQs
Can Indian residents buy ClearSign Technologies stock?
Yes. ClearSign Technologies (CLIR) has been listed on NASDAQ since 2012, in the Industrial - Pollution & Treatment Controls 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 ClearSign Technologies share cost in rupees?
One ClearSign Technologies share is $3.39 — about ₹326 at a USD/INR rate of 96.02 on 24 Sep 2026. Both the ClearSign Technologies 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 ClearSign Technologies 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 ClearSign Technologies?
Yes. One ClearSign Technologies share is $3.39, 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 ClearSign Technologies.
How are gains on ClearSign Technologies 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 ClearSign Technologies price. Paasa issues a capital-gains statement for your return.
Does ClearSign Technologies pay a dividend?
No. ClearSign Technologies 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 ClearSign Technologies 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 ClearSign Technologies 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 ClearSign Technologies 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 ClearSign Technologies holding, its cost and its closing value.
How do I sell ClearSign Technologies 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.
