What is Form 16?
Form 16 is a TDS certificate that an employer issues to you when TDS is deducted by the employer. An employer is required to deduct tax at source (therefore the name TDS - Tax Deducted at Source) when the employer pays salary to the employee (you). The employer deducts this tax on behalf of the Government and after deducting deposits the tax to the Government. The employer is then required to give a certificate to the employee giving the details of tax deducted. This certificate is called the Form 16.
In case no TDS has been deducted by the employer they may not issue you a Form 16.
You will require your Form 16 from your employer to file your tax return. You can directly upload your Form 16 and file your income tax return quickly.
