FAQs
Can I buy Tanvex BioPharma on Paasa?
Tanvex BioPharma (6541) has been listed on the Taiwan Stock Exchange since 2015, in the Biotechnology industry. Tanvex BioPharma is not currently available to trade on Paasa; the figures on this page are for information. Indian residents who hold it through another broker still declare it under the rules below.
How much does one Tanvex BioPharma share cost in rupees?
One Tanvex BioPharma share is NT$30.30 — about ₹91 at a TWD/INR rate of 3.01 on 30 Sep 2026. Both the Tanvex BioPharma price and the rupee rate move during the day, so the rupee cost changes with them.
What are the LRS and TCS rules for investing abroad 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.
How are gains on Tanvex BioPharma 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 TWD/INR rate on the purchase and the sale date, so the rupee move counts alongside the Tanvex BioPharma price.
Does Tanvex BioPharma pay a dividend?
No. Tanvex BioPharma 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.
When does TAI trade, in Indian time?
The Taiwan Stock Exchange trades 6:30 am – 11:00 am IST in Indian time.
Is Tanvex BioPharma a Taiwan company, and does that change how it is taxed?
Tanvex BioPharma trades on the Taiwan Stock Exchange in TWD, but the company is domiciled in Cayman Islands. Tanvex BioPharma trades as an ordinary share listed directly in Taiwan, not a depositary receipt. Your India-side capital-gains treatment is the same either way.
Do I have to declare Tanvex BioPharma 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. The holding is reported with its cost and its closing value.
Does the rupee rate affect what I make on Tanvex BioPharma?
Yes. Tanvex BioPharma is priced in TWD, so your rupee outcome combines the TWD move with the TWD/INR move between the day you remit and the day you convert back.
