LRS — $250k/FY ceiling, plus TCS on every transfer
Under RBI's Liberalised Remittance Scheme you can move up to $250,000 per Indian Financial Year (April–March) per individual. Since October 2023 most remittances above ₹7 lakh in an FY attract 20% Tax Collected at Source (refundable against your ITR but cash-locked until then). A spouse can have their own quota. For a $400k+ CBI investment, staging across two FYs with a cross-border tax professional coordinating both sides is the usual answer.
