Buying your first home as a couple? A joint home loan is often the single biggest lever you have. It can raise the amount you can borrow, double the tax relief in the old regime, and settle on paper who owns what. It also ties you both to the loan until the last EMI. This guide explains each part in plain words, with ₹ examples you can check yourself.
Every rule here was checked on 15 October 2026 against the Income Tax Department's e-filing help pages. Tax rules change, so check again when you file.
Co-applicant, co-borrower, co-owner: the difference
Banks use three words that sound alike but mean different things:
- Co-applicant or co-borrower: a person who signs the loan and is responsible for repaying it. Banks use these two words almost the same way. If the other person stops paying, the bank can ask you for the whole EMI.
- Co-owner: a person whose name is on the sale deed, the legal document that transfers the home to you. Ownership comes from the deed, not from the loan.
You can be one without the other. A spouse can co-sign the loan without owning a share, and many banks insist that every owner of the property signs the loan too. For tax, though, you need both: only a person who owns a share and repays the loan can claim the deductions. For most married couples buying a first home, the simple answer is to be co-owners and co-borrowers together.
How much more you can borrow
Banks do not lend a fixed multiple of your salary. They look at how much of your monthly take-home pay can safely go to EMIs, often about half, after counting any EMIs you already pay. With two incomes, that limit is worked out on the total.
A worked example. Say one spouse takes home ₹1.2 lakh a month and the other ₹80,000. Neither has other loans. The bank allows EMIs of up to 50% of take-home pay. At 8.5% a year for 20 years, the EMI is about ₹868 for every ₹1 lakh borrowed.
| Monthly EMI allowed | Loan it supports | |
|---|---|---|
| Higher earner alone | ₹60,000 | about ₹69 lakh |
| Both together | ₹1,00,000 | about ₹1.15 crore |
That is simple arithmetic: ₹60,000 ÷ ₹868 × ₹1 lakh, and ₹1,00,000 ÷ ₹868 × ₹1 lakh. Real offers vary by bank, age, job type and credit score. Try your own numbers in our home loan eligibility calculator.
A word of care. Being able to borrow more is not a reason to. Many first-home couples are happier with an EMI that still works if one income pauses for a baby, a job change or a sabbatical. Plan for that month before you plan for the biggest loan.
Both credit scores matter too. A weak score on one side can raise the rate for both of you, so check yours before you apply.
Tax: both claim 80C and 24(b) (old regime)
This is where a joint loan really pays. Each co-owner who repays the loan is treated as a separate taxpayer, with separate limits:
- Principal: each of you can count your share of the principal repaid towards the ₹1.5 lakh yearly limit under section 80C. That limit is shared with PF, PPF, life insurance and similar items.
- Interest: each of you can deduct up to ₹2 lakh a year of interest on a home you live in, under section 24(b).
A worked example. Say you borrow ₹80 lakh at 8.5% and own the home 50:50. The first year's interest is roughly ₹6.7 lakh. Alone, one person could deduct only ₹2 lakh of it. Together, each pays about ₹3.35 lakh and each deducts ₹2 lakh, so ₹4 lakh in all. If both of you are in the 30% slab, the extra ₹2 lakh of deduction saves about ₹62,400 a year (₹2 lakh × 31.2%, including the 4% cess). See your own figure in our home loan tax benefit calculator.
Three conditions catch people out:
- The old regime only. The new tax regime, now the default, does not allow the 80C deduction or interest relief on a home you live in. Each spouse chooses a regime separately, so it can be right for one of you to use the old regime and the other the new.
- Share follows ownership. Claims should match your ownership share and what each of you actually pays. Pay EMIs from a joint account or in the agreed ratio, and keep the bank's interest certificate in both names.
- Under-construction homes. Interest paid before you get possession is not lost. It is claimed in five equal parts from the year construction is complete, within the same ₹2 lakh limit. Principal counts for 80C only after possession.
One more change for 2026. The new Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026. It renumbers many sections, but the home-loan reliefs carry over in the same way: the same limits, and still for the old regime only. You will see new section numbers in returns from tax year 2026-27, so ask your tax adviser to map them for you.
Ownership share and the sale deed
Write the ownership share into the sale deed, for example 50:50 or 60:40. If the deed is silent, owners are generally presumed to own equal shares, which may not match who paid what.
A good rule: set the share close to how you will split the EMIs and down payment. It keeps your tax claims clean and avoids questions later. Bring both owners, both PAN cards and both Aadhaar cards on the day you register. Our Karnataka registration-day guide walks you through the visit to the sub-registrar's office.
Some states charge women a lower stamp duty. Check Karnataka's current rate before you plan your budget around it.
If you are also looking at the government's interest subsidy, note that it looks at your whole household, both of you together. Our guide to PMAY-Urban 2.0 for your first home explains who qualifies.
Women co-borrower rate concessions
Many lenders give women a small cut in the interest rate, usually about 0.05% a year. SBI and HDFC Bank have both long offered one. The condition is usually that a woman is the main applicant or a co-owner of the home.
On an ₹80 lakh loan, 0.05% is about ₹2,400 less interest in the first year, and more over 20 years. It is small next to the rate you negotiate, but there is no reason to leave it on the table. Put the wife's name first on the application if your bank asks for that, and ask for the women-borrower rate in writing.
What if one of you stops paying
This is the part couples rarely talk about, and should. On a joint loan, each borrower is liable for the whole loan, not just half. If one stops paying, the bank can ask the other for the full EMI, and a missed EMI marks both credit scores.
Some simple protections:
- Insure both incomes. A term insurance policy on each earner, for at least the loan amount, means the loan can be cleared if one of you dies.
- Keep a buffer. Six months of EMIs in savings covers a job loss or a gap between jobs.
- Know the exit. Taking a name off the loan needs the bank's approval. Usually the remaining borrower must qualify alone, or the loan is moved to a new lender in one name.
None of this is a reason to avoid a joint loan. It is a reason to set one up with your eyes open.
