Form 16 is a certificate issued by the employer providing a summary of salary paid and TDS deductions during the financial year.
It is divided into two parts - Form 16 (A) and Form 16 (B) containing details like salary breakup, exemptions, and deductions.
Deductions under Chapter VI-A include investments in insurance, pension funds, health insurance premiums, etc., outlined in Section 80C to Section 89 of the Income Tax Act.
Employees switching jobs in a year need to obtain Form 16 from each employer, and Form 16 is issued for taxable incomes falling under the basic exemption limit.
