1. Compensation is quoted as CTC, not salary
Indian offers are quoted as CTC — Cost to Company — meaning everything the employer spends on that person in a year. The employer EPF share, gratuity provisioning, group insurance and sometimes meal vouchers and telecom reimbursement are all inside the number.
So ₹12,00,000 CTC is not a ₹12,00,000 salary. Strip out the employer-side contributions and you get gross; take employee deductions off gross and you finally have take-home. Report CTC to head office for headcount cost, but talk to the employee in take-home terms, or the conversation goes wrong.
