Indian investors can now buy crypto ETFs by depositing INR in Indian exchanges or through the Liberalised Remittance Scheme (LRS) route. The LRS route allows investors to send up to $250,000 per year to a US brokerage account and take exposure to the ETF. However, using the LRS route may incur a 20% TCS on remittances above 7 lakhs.Trading on Indian exchanges does not have a TCS angle but involves a 1% TDS on selling and a 30% tax on profits. Investors can allocate around 10% or less to crypto ETFs and accumulate assets systematically.
