Taxable income includes salaries, wages, bonuses, etc., along with unearned income and investment income. Taxable income determines your tax liability.

  • You need to add the bonus received during the financial year as income for calculation.
  • The total you arrive at is your gross salary. From the gross salary, you reduce the exemptions such as House Rent Allowance, Transport Allowance (for which the maximum exemption is Rs.19,200 per year), Medical reimbursement (for which the maximum exemption is Rs.15,000), and all other reimbursements. You should provide bills for all these reimbursements.
