Frequently asked questions
Can I buy Costain stock from India?
Yes. Indian residents and NRIs can buy Costain (COST) shares directly through Paasa. Costain is listed on the London Stock Exchange, in the Engineering & Construction industry. Your money leaves India under the RBI's Liberalised Remittance Scheme and the shares are held in your own name at Interactive Brokers.
How are Costain dividends taxed for Indian investors?
The UK levies 0% withholding tax on company dividends paid to non-residents. Dividends are taxed at your slab rate in India. Costain’s current yield is 2.00%. Paasa's dividend report lists the gross dividend and any tax withheld for each payment, which is what you need when you file.
What tax do I pay in India when I sell Costain shares?
Non-residents are exempt from UK capital gains tax on the disposal of listed shares. In India, gains on shares held for more than 24 months are long-term and taxed at 12.5%, and gains on shares held for 24 months or less are short-term and taxed at your income-tax slab rate. Both are worked out in rupees at the GBP/INR rate on the day you bought and the day you sold, so the currency move is part of the gain. Paasa's capital-gains statement gives you the figures for your return.
What happens to my Costain shares if I pass away?
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. The rule looks at everything you hold there, not at Costain alone.
Is there stamp duty when I buy Costain shares?
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.
