Joint Home Loan: Tax Benefits and Eligibility for Bengaluru Buyers in 2026

A married couple buying a flat in Bengaluru in 2026 discovered that a small structuring decision, taking the home loan jointly, did two things at once. Their two incomes combined let them qualify for a larger loan than either could alone, and because both were co owners and co borrowers on the old tax regime, each could separately claim the interest and principal deductions, roughly doubling the household tax benefit. A joint home loan is one of the few decisions that can improve both your buying power and your tax position in a single move, but only if it is set up so that each person is genuinely both an owner and a borrower.

The short answer. A joint home loan is taken by two or more people together, and it helps in two ways. First, lenders combine the applicants' incomes, which raises how much you can borrow. Second, under the old tax regime, each person who is both a co owner and a co borrower can individually claim the interest deduction of up to 2 lakh under Section 24(b) and the principal deduction of up to 1.5 lakh under Section 80C, so a couple can potentially double the household deduction. The catch that matters most is the eligibility test: to claim, you must be both an owner of the property and a borrower on the loan, and you must actually contribute to the EMI. Confirm the rules on the Income Tax Department site and with a tax adviser.

What is a joint home loan?

It is a single home loan taken by two or more borrowers together, most often a married couple or close family. All the co borrowers are jointly responsible for repaying the loan, and the lender assesses their combined income and credit profiles when deciding how much to lend. A joint loan is usually paired with joint ownership of the property, so that the people on the loan are also the people on the title, though the two are legally distinct and it is the combination that unlocks the tax benefits. Choosing to borrow jointly is not just paperwork, it shapes who owns the home, who is liable for the debt, and who can claim the tax deductions, so it deserves a deliberate decision rather than a default choice at the bank counter.

How do the tax benefits multiply?

Because each qualifying co borrower gets their own set of deductions. Under the old tax regime, a single borrower can claim up to 2 lakh of home loan interest under Section 24(b) and up to 1.5 lakh of principal under Section 80C. In a joint loan where both parties are co owners and co borrowers, each of them can claim these limits individually, so a couple can together claim up to 4 lakh of interest and up to 3 lakh of principal, subject to their actual shares and the tax being paid on the old regime. We explain the two deductions separately in our guides to the Section 24(b) interest deduction and to Section 80C for home buyers. This doubling is the headline attraction of a joint loan, but it applies only under the old regime, so it must be weighed against the new regime's lower rates.

Who exactly can claim, the owner or the borrower?

Only someone who is both, which is the rule buyers most often get wrong. To claim the tax deductions on a joint home loan, a person must be a co owner of the property and a co borrower on the loan, and must actually contribute to the repayment. An owner who is not on the loan cannot claim, and a borrower who is on the loan but is not an owner of the property also cannot claim, and someone who is on paper but does not really pay the EMI is not entitled to the benefit either. This is why the structure has to be genuine: both names on the title, both names on the loan, and both actually paying. Setting this up correctly at the start, rather than trying to rearrange it later, is what secures the double benefit. A common and avoidable mistake is to add a spouse as a co borrower for eligibility, to get a bigger loan, but to leave the title in one name alone. That structure boosts borrowing power yet quietly forfeits the second set of deductions, because the co borrower is not an owner. If the tax doubling matters to you, the title must carry both names too, so decide the ownership and the loan structure together rather than treating them as separate errands.

How is the deduction split between us?

In the ratio of ownership and contribution, which banks often assume to be equal. The total interest and principal are allocated between the co owners in proportion to their share in the property and their contribution to the EMI, and in the absence of a specified split, a 50:50 division is commonly assumed. If your ownership shares are unequal, or one person pays more of the EMI, the deductions should follow that reality, so it is worth recording ownership shares clearly and paying the EMI from an account that reflects both contributions. The point is that the deductions are not simply doubled by having two names, they are shared according to who actually owns and pays, so align the paperwork with the substance to claim correctly and defensibly.

Does it really increase how much I can borrow?

Yes, because the lender adds the incomes together. When two people apply jointly, the bank considers their combined income against its fixed obligation to income limit, which usually allows a larger total EMI and therefore a bigger loan than either applicant could obtain alone. This is often the practical reason couples borrow jointly, since it can lift a shortlist from what one salary supports to a home the household can genuinely afford, a calculation we set out in our guide to CIBIL score and home loan eligibility. If you are stretching to reach a specific home, such as a flat in this Bengaluru project, a joint loan may be what makes it reachable. Remember though that the liability is joint too, so both incomes are now committed to the EMI, and a stretch that felt comfortable on two salaries can strain if one of them pauses.

What are the catches to watch?

Joint liability, the regime question, and what happens if circumstances change. Because both borrowers are jointly and severally liable, each is responsible for the whole EMI if the other cannot pay, so a joint loan ties two financial lives together and should be entered with that seriousness. The tax doubling applies only under the old regime, so if either of you is on the new regime, that person's deductions do not apply and the benefit shrinks. And you should think ahead about events such as one borrower stopping work, a separation, or the wish to sell, since untangling a joint loan and joint ownership is more involved than a single name arrangement. None of these are reasons to avoid a joint loan, but they are reasons to set it up thoughtfully and to keep a woman co owner's name on title where a rate concession or succession planning makes sense.

What should we check before taking a joint loan?

Work through this before you sign as co borrowers.

1. Put both names on the title and on the loan, so each is a co owner and a co borrower.
2. Ensure both parties actually contribute to the EMI, since only real contributors can claim.
3. Confirm you are on the old tax regime if you want the doubled deductions.
4. Record your ownership shares, since the deductions are split in that ratio.
5. Use the combined income to size the loan, but remember the liability is joint.
6. Plan for changes such as a job loss, separation or sale before they arise.
7. Consult a tax adviser to confirm each person's eligibility and the split.

Frequently asked questions

What are the tax benefits of a joint home loan? Under the old tax regime, each co borrower who is also a co owner can individually claim up to 2 lakh of home loan interest under Section 24(b) and up to 1.5 lakh of principal under Section 80C. So a couple can together claim up to 4 lakh of interest and 3 lakh of principal, subject to their ownership shares and both being on the old regime.

Who can claim tax benefits on a joint home loan? Only a person who is both a co owner of the property and a co borrower on the loan, and who actually contributes to the EMI. An owner who is not a borrower, or a borrower who is not an owner, cannot claim, and someone who does not really pay the EMI is not entitled to the benefit. Both names must be on the title and the loan.

Does a joint home loan increase how much I can borrow? Yes. Lenders combine the incomes of the co applicants when assessing eligibility, which usually allows a larger total EMI and a bigger loan than one applicant could get alone. This is a common reason couples borrow jointly, though it also means both incomes are committed to the repayment, since the liability is joint.

How is the deduction split in a joint home loan? The interest and principal are allocated between the co owners in the ratio of their ownership and their contribution to the EMI, with a 50:50 split commonly assumed if nothing is specified. If shares or contributions are unequal, the deductions should follow that, so record ownership shares clearly and pay the EMI in a way that reflects both contributions.
