What Form 12BB is, and why it matters

Form 12BB is a statement of the tax-saving claims a salaried employee makes to their employer, prescribed under Rule 26C for the deduction of TDS on salary under Section 192. You give it to your employer — it is not filed with the Income Tax Department. Based on it, your employer works out how much TDS to deduct each month. Typically you submit a provisional declaration early in the year and back it with proofs (rent receipts, premium receipts, interest certificates) before the year ends. If you do not submit it, the employer deducts higher TDS — though you can still claim the benefit later in your return.

The four heads of claim

#ClaimWhat you declare
1House Rent Allowance (HRA)Rent paid, and the landlord’s name, address and PAN. Landlord PAN is required if annual rent exceeds ₹1,00,000.
2Leave Travel Concession / AssistanceThe LTA/LTC amount claimed for eligible travel.
3Interest on home loan (Section 24)Interest payable/paid, and the lender’s name, address and PAN.
4Deductions under Chapter VI-ASection 80C/80CCC/80CCD and other sections (80D, 80E, 80G, 80TTA and so on) with amounts.

Proof to keep for each claim

ClaimEvidence to retain
HRARent receipts / rent agreement; landlord PAN where rent exceeds ₹1,00,000 a year
LTA / LTCTravel tickets and boarding passes
Home loan interestInterest certificate from the bank / lender
80C / 80D / 80E / 80G etc.Premium receipts, PPF/ELSS statements, donation certificate (Form 10BE), loan interest certificate
You do not attach the proofs to Form 12BB itself — you declare the amounts on the form and keep the evidence to give your employer when asked. Your employer verifies the proofs before allowing the deduction in your Form 16.

Old vs new regime — what is worth declaring

This is the point that trips people up. Under the new tax regime (the default), most Form 12BB claims are not available — HRA exemption, LTA, the home-loan interest deduction on a self-occupied house, and the common Chapter VI-A deductions (80C, 80D and so on) do not apply. The main things that survive under the new regime are the standard deduction and the employer’s NPS contribution under 80CCD(2). So Form 12BB is mostly worth completing if you have opted for, or intend to opt for, the old regime. If you are on the new regime, tell your employer that too so they do not withhold on the assumption of old-regime deductions.

How to submit

  • Fill Form 12BB with your expected claims for the year and give it to your employer (usually around April, and updated later).
  • Submit the supporting proofs before the cut-off your employer sets (commonly January–February).
  • Your employer factors it into the monthly TDS and reflects the allowed items in your Form 16.
Old vs new numbering (Income-tax Act 2025): from the tax year 2026-27 (income on or after 1 April 2026), Form 12BB is renumbered Form 124 under the Income-tax Act 2025 and the Income-tax Rules 2026. For the FY 2025-26 declaration you give your employer now, Form 12BB and Rule 26C continue to apply. The heads of claim and the evidence rules are unchanged — only the numbering changes.

Frequently asked questions

Is Form 12BB filed with the Income Tax Department?

No. Form 12BB is given to your employer, not to the department. It is the basis on which your employer computes the TDS to deduct from your salary under Section 192. The department sees the outcome through your Form 16 and your return.

When do I submit Form 12BB?

Usually at the start of the financial year (around April) as a provisional declaration, updated during the year, with the supporting proofs submitted before your employer’s cut-off (commonly January or February). If you miss it, the employer deducts higher TDS, which you can recover by claiming the deductions in your income tax return.

When is the landlord’s PAN required?

If the aggregate rent you pay during the year exceeds ₹1,00,000, you must report the landlord’s PAN in Form 12BB for the HRA exemption. Below that, the PAN is not mandatory but rent receipts are still needed.

Do I need Form 12BB under the new tax regime?

Mostly no. Under the new regime, HRA, LTA, home-loan interest on a self-occupied house and the usual Chapter VI-A deductions are not available; only items like the standard deduction and employer NPS (80CCD(2)) apply. If you are on the new regime, there is little to declare — but you should still tell your employer your regime choice so TDS is computed correctly.

What proofs do I attach to Form 12BB?

None are attached to the form itself. You declare the amounts on Form 12BB and separately give your employer the evidence — rent receipts, travel tickets, the lender’s interest certificate, and investment/premium receipts — when they ask for verification.

Is the generated form the official Form 12BB?

The generator produces a statement in the official Form 12BB format with your figures filled in, ready to print and sign. Always review it and confirm the details and current requirements before submitting it to your employer.

Is Form 12BB being renumbered under the Income-tax Act 2025?

Yes. From the tax year 2026-27, Form 12BB becomes Form 124 under the Income-tax Act 2025 and the Income-tax Rules 2026. For the FY 2025-26 declaration you give your employer now, Form 12BB and Rule 26C still apply, and the heads of claim are unchanged.
