Form 12BB
Form 12BB is the statement you give the employer so TDS under Section 192 can include the claims the law allows. Form 12BB is still that statement. This page does not treat a "Form 124" replacement as enacted.
Pay from an earlier employer in the same tax year is not a line on Form 12BB. That statement is Form 122 (earlier Form 12B and Form 12BAA), under section 392(4)(a). You furnish it at your option.
If you are in the new regime, most of the lines on the form do not reduce TDS. HRA, Section 80C, Section 80D, and your own extra NPS under Section 80CCD(1B) are old regime only. Employer NPS under Section 80CCD(2) still counts in both. The standard deduction is applied by payroll in both regimes: ₹75,000 in the new regime and ₹50,000 in the old regime.
What the form can carry, in the old regime:
- ✓ Rent paid, and the landlord's PAN if rent for the year is more than ₹1,00,000
- ✓ Home-loan interest (Section 24) and principal (Section 80C)
- ✓ Section 80C proofs, which share one ₹1,50,000 cap (employee EPF, PPF, ELSS, and the rest)
- ✓ Section 80D health-insurance premium
- ✓ Your own extra NPS under Section 80CCD(1B), up to ₹50,000
Employer NPS is not a receipt you attach. Ask HR to put it in the salary structure. The employer NPS page has the caps and a short email you can send.
When to send it: payroll sets the date, often in the first month. If the form is late, TDS for the months before it ignores those claims. You can still claim what the law allows when you file. Any refund comes after the return is processed, not on the next payslip.
