Form 12BB (Now Form 124): How Do You Submit Rent Receipts to HR?

Form 12BB is the investment declaration form prescribed under Rule 26C of the Income Tax Rules, 1962 (renumbered as Form 124 from 1 April 2026 under the Income Tax Rules, 2026). Salaried employees submit it to their employer at the start of each financial year (April) to declare planned investments and rent payments, then again in January–February with actual supporting proof. Employers use Form 12BB / Form 124 to compute correct TDS on salary. Missing or late submission means TDS is deducted on the full HRA amount, recoverable only via ITR refund.

Myth

Form 12BB is optional paperwork, so skipping it just means you claim HRA later in your return.

Fact

Form 12BB has been mandatory for every salaried Indian under Rule 26C[1] since 1 June 2016, and skipping it forces your employer to deduct TDS on the full HRA amount.

What is Form 12BB (now Form 124)?

Short answer

Form 12BB is the investment declaration form prescribed under Rule 26C of the Income Tax Rules, 1962[1], renumbered as Form 124[4] from 1 April 2026 under the Income Tax Rules, 2026.

  • Form 12BB has been in force for every salaried Indian since 1 June 2016.
  • You submit it to your employer to declare planned investments and rent payments so they can estimate TDS for the year.
  • The landlord PAN becomes mandatory the moment annual rent exceeds Rs. 1,00,000.
  • Missing the proof leaves the employer obliged to compute TDS on the full HRA amount under Section 192[3], now Section 392 under the Income-tax Act, 2025 for Tax Year 2026-27 onwards.

What do you include in the HRA section of Form 12BB?

Short answer

You declare four landlord and rent details, plus the landlord PAN whenever annual rent exceeds Rs. 1,00,000, on the official Form 12BB[2].

To verify the exact HRA exemption you should declare, run the numbers on our Tax Optimization Calculator. It applies the FY 2026-27 Rule 279 metro logic, so you do not need to memorise which cities take the 50% cap.

  • Name and address of your landlord.
  • Landlord's PAN, mandatory if annual rent exceeds Rs. 1,00,000; see our HRA-without-landlord-PAN guide if your landlord refuses.
  • Monthly rent amount.
  • Rental period, stated from month to month.
  • Attach your rent receipts, one per month, as supporting documents.

When do you submit Form 12BB?

Short answer

Most employers follow a two-stage process under Rule 26C[1]: an April estimate and a January-February submission with actual proof.

  • April: submit Form 12BB with estimated figures, no receipts needed yet.
  • January-February: submit Form 12BB again with actual receipts for the full year.
  • Some employers ask for quarterly submissions instead.
  • Check with your HR department for your company's specific schedule.

What happens if you do not submit rent receipts?

Short answer

Your employer deducts TDS on the full HRA component under Section 192[3], and you recover the exemption only via an ITR refund.

You can still claim the exemption while filing your ITR and get a refund.

This delays your money and may trigger queries from the IT department.

What are the common Form 12BB mistakes to avoid?

Short answer

The frequent errors are a missing landlord PAN when rent exceeds Rs. 8,334/month, unsigned receipts, mismatched periods, and claiming HRA under the New Tax Regime where it is not allowed.

For the underlying HRA math, see how to calculate HRA exemption.

  • Missing landlord PAN when rent exceeds Rs. 8,334/month.
  • Receipts without the landlord's signature.
  • Mismatched periods, where receipt dates do not cover the full claim period.
  • Claiming HRA under the New Tax Regime, which is not allowed; see income tax slabs FY 2026-27 for the regime comparison.
  • Both spouses claiming HRA on the same property.
