Joint Home Loan and Co-ownership for Bengaluru Buyers

When a Bengaluru couple bought a flat together in 2026, they assumed that putting both names on the loan would automatically double their tax savings. Their accountant pointed out a catch they had missed: the wife was a co borrower on the loan but not a co owner on the sale deed, so she could not cleanly claim the deductions at all. A small change to the paperwork, made before registration, was all that stood between one set of tax benefits and two, and it would have been almost impossible to fix afterwards. Joint home loans can genuinely multiply your tax relief, but only when ownership, borrowing and payments line up, which is a matter of planning rather than luck.

The short answer. On a joint home loan, each person who is both a co owner and a co borrower can separately claim up to 2 lakh rupees of interest under Section 24b and up to 1.5 lakh of principal under Section 80C, in proportion to their ownership share. For a couple that can mean a combined benefit of around 7 lakh rupees a year under the old tax regime. The trade off to understand: these home loan deductions are available only under the old regime, so if you have opted for the new regime, the joint structure gives you no extra tax benefit.

What is a joint home loan and who should be on it?

A joint home loan is a single loan taken by two or more people together, typically a couple or close family members, who share the responsibility for repaying it. Lenders often encourage it because two incomes can support a larger loan and reduce the risk of default, which is why a joint loan can also help a buyer qualify for the home they actually want. For buyers, the joint structure has two attractions: it can improve your loan eligibility by pooling two incomes, and it can, in the right conditions, let each borrower claim home loan tax deductions separately. But the tax advantage is not automatic, and it depends on getting the ownership and borrowing structure right before you register. The people you put on the loan and on the sale deed should therefore be chosen deliberately, with both the repayment capacity and the tax position in mind, rather than added as an afterthought at the bank counter. A decision that takes five minutes to fix before registration can be slow, costly or impossible to correct once the deed is signed.

How do co-owners split the tax benefit on a joint home loan?

Each co owner who is also a co borrower can claim the deductions separately, up to the individual limits, in proportion to their share in the property. That means each eligible person can claim up to 2 lakh rupees a year of interest under Section 24b and up to 1.5 lakh of principal repayment under Section 80C, within the overall 80C ceiling. For a couple who each own half the flat and are both on the loan, the household can therefore claim up to about 7 lakh rupees in a year, made up of 3.5 lakh each, being 2 lakh of interest and 1.5 lakh of principal per person, far more than the 3.5 lakh a single borrower on the same loan could claim on their own. The important discipline is that your split has to follow the ownership percentage recorded on the property papers, not simply who happens to transfer more money each month. So if you want to divide the benefit equally, the ownership share and the loan should be structured to support that from the start.

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

To claim the deductions cleanly, a person must be both an owner of the property and a borrower on the loan, because the two roles do different things. Ownership, recorded on the sale deed, is what entitles you to the tax benefit on the property, while being a co borrower is what ties you to the loan whose interest and principal you are claiming. If someone is only a co borrower but not a co owner, as in the case of the couple above, the deduction claim does not stand cleanly, because they do not own the asset. Conversely, a co owner who is not on the loan has nothing to claim, because they are not repaying it. This is why the safe approach is to align the names on the sale deed with the names on the loan, and to sort this out before registration rather than trying to correct it later. Adding a name to a sale deed after the fact can trigger fresh stamp duty and paperwork, so it is far cheaper to get it right the first time.

Does the tax regime you choose matter?

Yes, and this is the point most likely to catch buyers out: the home loan deductions under Section 24b and Section 80C are available only under the old tax regime. If you have opted for the new tax regime, with its lower slab rates and fewer deductions, you cannot claim these home loan benefits, and the whole calculation of doubling relief through a joint loan simply does not apply. So before you structure a joint loan mainly for the tax saving, work out whether you and your co owner are actually on the old regime and will genuinely benefit from the deductions, or whether the new regime, with its lower rates, leaves you better off overall despite losing the deductions. This is a genuinely personal calculation, and it is worth doing the maths, or asking a tax adviser, rather than assuming the joint loan automatically pays off. The table below sets out the key conditions.

What should a couple check before taking a joint home loan?

You should align ownership, borrowing and your tax regime, and confirm the numbers before you sign. The checklist below helps a couple set up a joint loan sensibly.

1. Decide the ownership shares in advance and ensure both intended claimants are named on the sale deed.
2. Ensure the same people are named as co borrowers on the home loan.
3. Check whether you and your co owner are on the old or the new tax regime.
4. Estimate each person's likely share of interest and principal to see who can actually use the limits.
5. Keep the loan repayments flowing from accounts that reflect your intended split, so the paper trail supports it.
6. Retain the annual loan interest and principal certificates from the lender for each year's tax filing.
7. Confirm your specific position with a tax adviser before relying on the double benefit.

How does a joint loan affect liability if one person cannot pay?

A joint home loan usually makes each borrower jointly and severally liable, which means the lender can recover the full outstanding amount from any one of them, not just their notional share. This is the side of a joint loan that gets less attention than the tax benefit, but it matters just as much. If one co borrower loses their income or the relationship between the borrowers breaks down, the bank still expects the full EMI, and the burden can fall entirely on the other person. It also affects each borrower's credit record and their capacity to take future loans, since the whole liability sits on both credit reports. None of this is a reason to avoid a joint loan, which is often the sensible way to buy, but it is a reason to enter it with open eyes, to keep the repayments current, and to think through, calmly and in advance, what would happen if circumstances changed for either borrower. A frank conversation at the start is far easier than an argument later.

Frequently asked questions

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. Each can then claim up to 2 lakh rupees of interest under Section 24b and up to 1.5 lakh of principal under Section 80C, in proportion to their ownership share. Under the old regime that can total around 7 lakh a year for a couple.

Do I need to be a co-owner to claim the deduction?

Yes. To claim home loan deductions you must be both a co owner of the property and a co borrower on the loan. A co borrower who is not on the sale deed cannot cleanly claim, and a co owner not on the loan has nothing to claim. Align both sets of names before you register.

Does the new tax regime allow joint home loan benefits?

No. The home loan deductions under Section 24b and Section 80C are available only under the old tax regime. If you have opted for the new regime, you cannot claim these benefits, so the tax advantage of a joint loan does not apply. Work out which regime leaves you better off before structuring the loan for tax.

How is the joint home loan tax benefit split between owners?

The benefit is split in proportion to each person's ownership share recorded on the property papers, not according to who pays more each month. So if you want an equal split, the ownership share and the loan should be structured to support that from the start. Keep repayment records consistent with the intended split for a clean claim.
