How to get Form 12B from previous employer?
Form 12B is different from Form 12BB. Form 12B is a salary certificate from your previous employer (used when you switch jobs mid-year). Contact your previous employer's HR or payroll team and request Form 12B. They may provide it in PDF, Form 12B word format, or printed. Form 12BB is the investment declaration you submit to your current employer.
