@Chirag: the answer to your question will depend upon your residential status, which is Resident Indian. Income paid by way of (living) allowance to an employee in the UK becomes
taxable both in India and in the UK. However, since India and UK have a DTAA (double taxation avoidance agreement) in force, India shall tax only the net amount of income not taxed in UK. For the exact amount of tax payable in India, you may get in touch with your employer HR department.
