A married couple in Bengaluru had their hearts set on a flat in Hebbal, but on one salary the bank would not lend quite enough, and the tax break on the loan felt modest. Their loan officer suggested a small change that solved both problems at once. By making the wife a co-owner and co-borrower, the couple could combine their incomes to qualify for a larger loan, and each could claim the home loan deductions separately, roughly doubling the tax benefit. Nothing about the flat changed. The way they structured the ownership and the loan did, and it made the same home both more affordable and more tax efficient.

The short answer. A joint home loan, taken by two people who are both co-owners and co-borrowers, lets each of them claim the home loan tax deductions on their own share. Under the old tax regime, each can claim up to 2 lakh rupees of interest under Section 24(b) for a self occupied home and up to 1.5 lakh rupees of principal under Section 80C, so a couple can claim far more together than one borrower could alone. The trade off is that both must genuinely co own the property and repay the loan, and the deductions follow the share of ownership and repayment, not a wish.

These benefits sit in the income tax law, as guides such as ClearTax set out. Here is how a Bengaluru couple can use them properly.

What makes a home loan a joint home loan?

A joint home loan is one taken by two or more people together, who share the responsibility to repay it. Commonly it is a couple, but it can be a parent and child or siblings, provided the lender accepts them. All the joint borrowers are liable for the loan, which is part of why lenders are willing to combine their incomes when deciding how much to lend. The joint structure is what opens the door to both a larger loan and a larger combined tax benefit.

But taking the loan jointly is only half the picture. The tax benefits depend on a second condition that many buyers overlook, which is who actually owns the property on paper.

Why must you be both a co-owner and a co-borrower?

You must be both because the law ties the deductions to ownership and to the loan at the same time. To claim the home loan deductions, you have to be a co-owner of the property and a co-borrower on the loan. Someone who owns a share but is not on the loan cannot claim the interest or principal, and someone who is on the loan but does not own the home cannot claim it either. Both boxes must be ticked for each person who wants the benefit.

This matters when a couple casually puts the home in one name but takes the loan jointly, or the reverse. In either case only the person who is both an owner and a borrower can claim, and the intended doubling of the deduction is lost. Getting both the sale deed and the loan documents to reflect both partners is the step that unlocks the benefit.

It helps to name the roles precisely. A co-borrower who is not a co-owner is effectively guaranteeing the loan without gaining ownership or a tax benefit, while a co-owner who is not a co-borrower owns a share but cannot claim the deductions. Neither halfway position gives a partner the full benefit. If the goal is to share both the home and the tax break, both partners need to appear on both documents, and it is worth checking that the lender and the sub registrar have actually recorded them correctly rather than assuming it.

How do joint owners double the tax deductions?

Joint owners double the deductions because each of them claims the limits separately on their own return. Under the old tax regime, each co-owner who is also a co-borrower can claim up to 2 lakh rupees of interest under Section 24(b) for a self occupied home and up to 1.5 lakh rupees of principal under Section 80C. Two qualifying partners therefore have two sets of limits, not one shared set. The table below shows how the numbers change when a single borrower becomes two co-owners.

How is the deduction split between co-owners?

The deduction is split in proportion to each owner's share and the interest each actually pays. The total interest on the loan is allocated to the owners in the ratio of their ownership, and the same logic applies to the principal. If a couple own the home equally and repay equally, they split the deductions evenly. If they own equally but one repays sixty percent, the benefits follow that sixty forty split. So the paperwork should reflect reality, because the tax office looks at who owns and who pays, not simply whose name is first.

This is also why keeping clean records matters. Paying the EMI from a joint account, or in shares that match the ownership, makes it straightforward to claim the deductions each partner is entitled to and avoids disputes if the return is ever questioned.

How does a joint loan improve your eligibility?

A joint loan improves eligibility because the lender can consider the combined income of the co-borrowers. Two incomes support a larger EMI than one, so a couple can often qualify for a bigger loan together than either could alone, which was exactly what let the Hebbal couple reach their target flat. This is separate from the tax benefit but frequently the more important reason to borrow jointly, since it can decide whether a home is within reach at all. Our guide to how much you can borrow and the down payment you need explains the other limits that sit alongside income.

A joint loan can also help when one applicant has a thinner credit record, since a co-borrower with strong credit can strengthen the application. As always, both borrowers remain fully responsible for the loan, so the decision should be made with open eyes about that shared liability.

What should a Bengaluru couple weigh?

Weigh the larger loan and doubled deductions against the shared liability and the need to structure ownership properly. The benefits are real, but they only arrive if both partners are co-owners and co-borrowers, if you file under the old regime to access the deductions, and if the repayment matches the ownership share. It is worth reading our guide to home loan tax benefits alongside this one, since the old versus new regime choice decides whether these deductions are available at all. For a sense of the ticket size where a joint loan often makes the difference, a project such as Abhee on Bellary Road in Jakkur sits in the range where two incomes frequently do the work one cannot.

The practical move is to decide the ownership split and the loan structure before you sign, with both the sale deed and the loan reflecting both partners. Fixing this after the fact is far harder than getting it right at the start.

There is a longer term benefit too. Clear joint ownership makes succession simpler, since a surviving co-owner already holds a recorded share rather than having to establish a claim later. That said, joint ownership also means neither partner can sell or mortgage the whole property alone, so it suits partners who plan to hold the home together for the long run. As with the loan, the tidy time to settle these questions is before you sign, not after a disagreement has already arisen.

What should you set up before you sign?

Run through these seven steps so the joint structure actually delivers its benefits.

1. Add both partners as co-owners on the sale deed if you both want to claim deductions.
2. Ensure both partners are co-borrowers on the loan, not just one.
3. Decide the ownership share deliberately, since deductions follow it.
4. Repay the EMI in shares that match the ownership, ideally from a joint account.
5. Remember each co-owner can claim up to 2 lakh interest and 1.5 lakh principal.
6. File under the old tax regime, since these deductions are not available in the new one.
7. Have each co-owner claim their share in their own income tax return.

Can both husband and wife claim home loan tax benefits?

Yes, if both are co-owners of the property and co-borrowers on the loan. Under the old tax regime, each can separately claim up to 2 lakh rupees of interest under Section 24(b) for a self occupied home and up to 1.5 lakh rupees of principal under Section 80C. The deductions are split in the ratio of ownership and the interest each actually pays.

Do I need to be a co-owner to claim deductions on a joint loan?

Yes. You must be both a co-owner of the property and a co-borrower on the loan to claim the deductions. A person who is only on the loan but does not own the home cannot claim, and an owner who is not on the loan cannot claim either. Both conditions must be met for each person seeking the benefit.

Does a joint home loan increase how much I can borrow?

Usually yes. Lenders can consider the combined income of the co-borrowers, so two incomes typically support a larger loan than one. This is often the main reason couples borrow jointly. Both borrowers remain fully liable for the loan, so the larger amount comes with shared responsibility that should be considered carefully.

How are the deductions divided between co-owners?

They are divided in proportion to each owner's share and the amount each actually repays. The interest and principal are allocated to the owners in the ratio of their ownership, adjusted for who pays what. Owning and repaying equally means an even split, while an unequal split of repayment shifts the deductions accordingly, so keep clear records of the payments.
