Joint Home Loan: Eligibility, Tax Benefits and Risks

A joint home loan lets two or more people, usually spouses or a parent and child, combine incomes to borrow more and, in the old tax regime, each claim their own home loan deductions. As of October 2026, a couple who co-own a self-occupied house can together deduct up to ₹4 lakh of interest and up to ₹3 lakh of principal a year. The price is that every co-borrower is liable for the entire loan, not just their share.

This guide covers who can apply, how much more you can borrow, the tax rules, and what to settle before you sign.

Co-borrower, co-owner and guarantor: not the same thing

Most lenders insist that every co-owner of the property joins as a co-borrower. The reverse is not always true: a parent may be a co-borrower to boost eligibility without being on the title. Our article on co-applicant and guarantor liability covers what happens when things go wrong.

Lenders typically allow close relatives as co-borrowers: spouse, parents, children and sometimes siblings. Unmarried partners and friends are usually not accepted as co-borrowers by most banks.

Higher eligibility: worked example

Neha earns ₹1.1 lakh a month take-home and her husband Arjun earns ₹70,000. Their lender caps total EMIs at 50% of net income (FOIR). At an illustrative 8.5% for 20 years:

The loan is still capped by RBI's loan-to-value limits as of October 2026: 90% for loans up to ₹30 lakh, 80% above ₹30 lakh to ₹75 lakh, and 75% above ₹75 lakh. A ₹1.04 crore loan needs a property valued at about ₹1.38 crore or more. The full method is in our guide to home loan eligibility and documents.

Higher eligibility is not the same as affordability. If one income stops, can the other carry ₹90,000 a month? Run the EMI calculator at the amount one of you could pay alone.

Lenders also look at both credit scores. A weak score for one co-borrower can raise the rate or lead to rejection, so check both reports first.

Tax benefits of a joint home loan

Under the old tax regime, as of FY 2026-27, each co-borrower who is also a co-owner and contributes to the EMI can claim separately:

• Interest: up to ₹2 lakh a year for a self-occupied house, under old Section 24(b), now Section 22 of the Income-tax Act, 2025.
• Principal: within their own ₹1.5 lakh limit under old Section 80C, now Section 123, along with stamp duty and registration in the year paid.

Claims should follow ownership share and actual payment. If Neha owns 50% but pays 70% of the EMI, a tax professional may advise adjusting the ownership ratio at the time of purchase rather than claiming out of proportion later.

Example: tax saved on a ₹90 lakh loan

Loan ₹90 lakh at 8.5% for 20 years, EMI ₹78,104. In year one, interest is about ₹7.58 lakh and principal about ₹1.79 lakh. Both are in the 30% slab, old regime, with 4% cess, and own the house 50:50.

The joint structure doubles the interest deduction here. Whether the principal deduction adds anything depends on how much of each person's ₹1.5 lakh limit is already used by EPF, PPF or insurance.

The new regime changes this. Under the default new regime, no interest or principal deduction is allowed for a self-occupied home. If both of you are better off in the new regime, the tax argument for a joint loan disappears. Details are in our home loan tax benefits guide.

Other advantages

• Stamp duty concessions for women: several states charge women buyers less as of October 2026, for example Delhi (4% against 6% for men) and Uttar Pradesh (a 1 percentage point concession up to a value cap). Some states extend part of the benefit to joint ownership with a woman. Confirm on your state's registration portal.
• Lower rate offers: some lenders give a small rate concession, often around 0.05 percentage point, when a woman is the primary borrower or co-owner.
• Shared ownership reflects joint contribution, which helps in succession and in divorce settlements.

Risks to settle before signing

1. Joint and several liability. The bank can recover the full EMI from either borrower. Paying "your half" is not a defence if the other stops paying.
2. Credit score linkage. Every missed EMI shows on both CIBIL reports and limits both people's future borrowing.
3. Divorce or separation. The loan does not split automatically. One person must refinance in their own name, or the house is sold. Transferring a share usually needs a registered release or gift deed.
4. Death of a co-borrower. The survivor owes the whole loan. Each earning co-borrower should hold term insurance at least equal to the outstanding loan; a lender-sold single-premium cover is optional and often costlier.
5. Family disputes. When a parent or sibling is a co-owner, agree in writing on who pays what and what happens on sale.

Joint loan or one borrower: a quick test

A joint loan is most useful when at least two of these are true:

• One income alone cannot support the loan you need, but the two together can with room to spare.
• Both of you will stay in the old tax regime and each has enough interest to use the ₹2 lakh limit.
• You both want legal ownership of the home, and both contribute to the down payment and EMIs.
• You live in a state where a woman co-owner lowers the stamp duty.

If only one person earns, the other's name on the loan adds liability without adding eligibility, so a single borrower with the spouse as co-owner (where the lender permits) may be simpler.

How to apply

1. Decide ownership shares based on who will contribute, and record them in the sale deed.
2. Check both credit reports and fix errors before applying.
3. Gather KYC, income proof and bank statements for every applicant.
4. Compare rates and processing fees from at least three lenders.
5. Read the sanction letter and Key Facts Statement together, and confirm both names on the loan agreement.
6. Set up the EMI from a joint account, or from each person's account in proportion, so payment records support tax claims.

Key takeaways

• A joint home loan combines incomes; in our example, eligibility rose from about ₹63 lakh to ₹1.04 crore.
• In the old regime, each co-owner co-borrower can claim up to ₹2 lakh interest and their own ₹1.5 lakh principal limit as of FY 2026-27.
• The new regime gives no deduction on a self-occupied home, for either borrower.
• Every co-borrower is liable for the whole loan, and the account affects every co-borrower's credit score.
• Agree on contributions, ownership shares and term insurance before signing.
