FAQs

Can Indian residents buy Costain stock?

Yes. Costain (COST) has been listed on the London Stock Exchange since 1988, in the Engineering & Construction 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 GBP. Shares are held in your own name at Interactive Brokers, segregated from Paasa's own assets.

How much does one Costain share cost in rupees?

One Costain share is £2.60 — about ₹330 at a GBP/INR rate of 127.06 on 29 Sep 2026. Both the Costain 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 Costain 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 Costain shares taxed in India?

Non-residents are exempt from UK capital gains tax on the disposal of listed shares, 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 GBP/INR rate on the purchase and the sale date, so the rupee move counts alongside the Costain price. Paasa issues a capital-gains statement for your return.

Does Costain pay a dividend, and how is it taxed in India?

Yes. Costain pays a dividend and the current yield is 2.00%; the last declared dividend was £0.04 per share, about ₹5.34. Dividends are taxed at your slab rate in India. The UK levies 0% withholding tax on company dividends paid to non-residents. Paasa's dividend report lists the gross dividend and any tax withheld for each payment.

When can I trade Costain from India?

The London Stock Exchange trades 12:30 pm – 9:00 pm IST in Indian time. The window shifts to 1:30 pm – 10:00 pm IST when the UK is on standard time. Orders can only execute during that window.

Is there estate or inheritance tax on Costain shares held from India?

Shares in UK-incorporated companies are UK-situs assets and fall within UK Inheritance Tax, charged at 40% above the £325,000 threshold for non-residents. It applies to your overall holdings in that jurisdiction rather than to any one position.

Are there transaction taxes when buying Costain?

The UK charges 0.5% Stamp Duty Reserve Tax when buying direct company shares electronically on the LSE; ETFs and UCITS funds do not attract it. This is charged by the market, not by Paasa.

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

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

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