Quick summary

Form 124 is the statement an employee gives the employer to claim HRA, LTA, home loan interest and Chapter VIII deductions while TDS is calculated. It replaces Form 12BB from 01/04/2026.
It has Part A (your details) and Part B (claims and evidence), and is filed once a year with the employer. It is not uploaded on the income tax portal.
For HRA you give the landlord’s name, address, PAN, Aadhaar, relationship, if any, and the rent paid. Landlord PAN is a must if yearly rent exceeds ₹1,00,000.
If you do not submit it, the employer deducts TDS without allowing any deduction or exemption.

How to submit Form 124 to your employer

1. Check your salary structure for HRA and LTA

↓

2. Collect rent agreement, travel proofs, loan and investment documents

↓

3. Fill Part A with your name, address, PAN, contact details and tax year

↓

4. Fill Part B with the claims you want considered

↓

5. Sign the declaration and hand it to your employer, online or on paper

Every year your employer deducts tax at source (TDS) from your salary. To deduct the right amount, the employer needs to know about your rent, travel, home loan and investments. You tell the employer through a statement. Until 31/03/2026 this was Form 12BB. From 01/04/2026 under the Income-tax Rules, 2026 it is Form 124.

Form 12BB and Form 124 side by side

	Old	New
Form	Form 12BB	Form 124
Rule	Rule 26C, Income-tax Rules, 1962	Rule 205, Income-tax Rules, 2026
Section	Section 192 of the 1961 Act	Section 392(5)(b) of the Income-tax Act, 2025

Who files it, and when?

An employee gives it to the current employer, once every financial year, as early as possible so the TDS is calculated correctly. It is only needed if you want your claims considered. If you do not submit it, the employer deducts TDS without allowing any deduction or exemption, and you can claim them later in your own return.

If you change jobs in the year, give the new employer your details of income and TDS from the old employer (Form 122), along with a fresh Form 124.

What does the form contain?

Part A: employee details. Name, address, PAN, email id, contact number and tax year.

Part B: claims and evidence.

House rent allowance: name and address of the landlord, landlord’s PAN, Aadhaar, relationship with the landlord (if any) and the rent paid. Give a copy of the rent agreement.
Leave travel concession or assistance: the travel details, with documents supporting the claim.
Interest on borrowing: name and address of the lender, lender’s PAN where available and the interest paid or payable. Give a copy of the loan agreement.
Deductions under Chapter VIII (A and B): the sections you claim, for example section 123 (the old section 80C), section 124 (NPS), section 129 (education loan interest), section 130, section 131 and section 153 (interest on deposits), with proofs.
Other details as an annexure.

Then comes your declaration that the information is complete and correct.

Landlord PAN

The PAN of the landlord must be furnished if the rent in the year is more than ₹1,00,000. Aadhaar is not mandatory unless your employer asks for it.

Do I file it on the portal?

No. Form 124 goes to your employer, electronically or on paper. It is not uploaded separately on the income tax portal.

Before you fill it

Check that HRA and LTA are part of your salary structure. If they are not, there is nothing to claim.
Collect the rent agreement and rent receipts, travel tickets, the home loan interest certificate and the investment proofs.
Remember that most of these claims work only in the old tax regime. Tell your employer which regime you choose.

Documents you may need

Claim	Supporting document
House rent allowance	Rent agreement, rent receipts or bank proof, landlord’s PAN if rent is above ₹1,00,000 a year
Leave travel allowance	Tickets, boarding passes or invoices
Home loan interest	Loan agreement and the lender’s interest certificate
Section 123 items: PPF, ELSS, life insurance, tax-saver FD, NSC, tuition fees	Receipts, certificates, passbook
Health insurance premium (80D)	Premium receipts
Education loan interest	Lender’s certificate showing interest paid
Disability deductions	Medical authority’s certificate
Donations	Valid receipts in your name

A few tips

If you pay rent to your parents, make the payments by bank transfer and ask them to show it as income in their return.
Do not submit false rent receipts. It can lead to action by the tax department.
Declare only what you really expect to spend. If you do not invest later, your TDS may be short and you will pay more tax when you file.
You can still claim missed deductions in your return, so do not worry if you could not give every proof to your employer.
