Joint Home Loan Tax Benefits: How Co-Borrowers Can Save Tax

Taking a joint home loan can make it easier to qualify for a larger loan because lenders may consider the combined income of the co-borrowers. It can also provide tax benefits to eligible co-owners, but those benefits do not automatically apply just because two people are listed on the loan.

For a co-borrower to claim home loan deductions, ownership of the property, participation in the loan, actual repayment contribution, property status and the applicable tax regime all matter.

For Assessment Year 2026-27, the Income Tax Department confirms that the old tax regime allows eligible deductions under Section 80C and Section 24(b), while the new tax regime has different rules, particularly for self-occupied property.

What Is a Joint Home Loan?

A joint home loan is a housing loan taken by two or more borrowers to purchase, construct or, where applicable, finance a residential property. Each borrower is responsible for repayment according to the loan agreement.

Common combinations include:

• Husband and wife
• Parent and child
• Siblings
• Other family members, subject to the lender’s eligibility criteria

Banks and housing finance companies generally assess factors such as income, credit history and repayment capacity before approving the loan.

One important distinction is that a co-borrower and a co-owner are not necessarily the same thing. Being named on the loan alone does not automatically create an entitlement to claim every available tax deduction.

Who Can Claim Tax Benefits on a Joint Home Loan?

A person generally needs to satisfy the relevant conditions for the particular deduction being claimed.

For joint home loan tax benefits, the practical requirements include:

1. You should have an ownership interest in the property

Your name should appear in the relevant property ownership documents. Simply paying EMIs on a property owned by someone else does not, by itself, make you eligible to claim the owner’s home loan deductions.

2. You should be a co-borrower

Your name should be included in the home loan agreement. The loan and property documents should be consistent with the actual ownership and borrowing arrangement.

3. You should contribute towards repayment

The tax claim should be supported by the actual financial arrangement between the co-owners. Keep clear records of who is paying the EMIs and in what proportion.

4. The deduction must be available under the applicable tax regime

This is particularly important because the treatment of home loan deductions differs between the old and new tax regimes. For example, interest on borrowed capital for a self-occupied property is not allowed under Section 24(b) in the new tax regime.

What Tax Benefits Are Available on a Joint Home Loan?

For eligible taxpayers choosing the old tax regime, two provisions are particularly relevant:

• Section 80C for eligible principal repayment and certain other qualifying payments
• Section 24(b) for eligible home loan interest

Section 80C: Principal Repayment

Eligible principal repayment of a housing loan can form part of the Section 80C deduction.

The combined Section 80C limit is ₹1.5 lakh per individual per financial year. This is not an exclusive home loan limit because other eligible investments and payments can also use the same overall Section 80C limit.

Certain other property-related payments, such as eligible stamp duty and registration charges, can also qualify under Section 80C, subject to the applicable conditions.

Therefore, if two eligible co-owners independently satisfy the conditions, each may be able to claim eligible amounts within their own Section 80C limit.

Section 24(b): Home Loan Interest

Under the old tax regime, interest paid on a qualifying home loan for a self-occupied property can generally be deducted up to ₹2 lakh per individual per year, subject to the conditions of the Income Tax Act.

For a let-out property, the actual eligible interest can be considered under Section 24(b), although restrictions apply to how much loss from house property can be set off against other income in a financial year. The Income Tax Department currently states that the set-off limit is ₹2 lakh, with eligible unabsorbed loss subject to the applicable carry-forward rules.

Joint Home Loan Tax Benefit Example

Suppose a husband and wife jointly purchase a house and take a ₹60 lakh home loan.

Assume, for illustration, that during a financial year:

• Interest paid: ₹4 lakh
• Principal repaid: ₹3 lakh
• Both are co-owners and co-borrowers
• Their ownership and repayment arrangement supports an equal claim

The ₹4 lakh interest could potentially be divided equally, giving ₹2 lakh of interest to each co-owner. Similarly, the ₹3 lakh principal repayment could be divided equally, giving ₹1.5 lakh to each.

Subject to all applicable conditions and the tax regime:

Taxpayer	Interest under Section 24(b)	Principal under Section 80C
Husband	₹2 lakh	₹1.5 lakh
Wife	₹2 lakh	₹1.5 lakh
Combined	₹4 lakh	₹3 lakh

This gives a potential combined deduction of ₹7 lakh under the two provisions, although the actual tax saving depends on each person’s taxable income, tax regime and eligibility.

The ₹1.5 lakh Section 80C figure is also a combined limit covering other eligible Section 80C payments, so it should not automatically be treated as an additional ₹1.5 lakh exclusively for the home loan.

What Happens to Pre-Construction Interest?

If you take a loan for a property that is still under construction, the treatment of interest is different.

Eligible interest relating to the pre-construction period can generally be accumulated and claimed in five equal annual instalments, beginning from the year in which construction is completed or the property is acquired, subject to the applicable conditions.

For example, if eligible pre-construction interest is ₹5 lakh, the amount may be claimed at ₹1 lakh per year over five years, in addition to the eligible interest deduction for the relevant year, subject to the applicable limits and rules.

Because the tax treatment depends on the nature and status of the property, the loan and the applicable tax regime, buyers should retain the lender’s interest certificate and supporting documents.

How to Claim Joint Home Loan Tax Benefits

Step 1: Check the Ownership Structure

Confirm that the people intending to claim the deductions have the required ownership interest in the property.

Step 2: Check the Loan Agreement

Make sure the relevant co-borrowers are correctly listed in the home loan documents.

Step 3: Keep the Ownership and Repayment Arrangement Clear

If ownership shares are unequal, maintain documentation that reflects the actual arrangement. Do not assume that every joint property automatically has a 50:50 ownership ratio.

Step 4: Obtain the Home Loan Certificate

Ask the lender for the annual home loan interest certificate or statement showing the principal and interest components.

Step 5: Maintain EMI Payment Records

Keep bank statements and other payment records showing who actually contributed towards the loan repayment.

Step 6: Claim the Applicable Deductions in Your ITR

Eligible taxpayers can claim the relevant deductions while filing their Income Tax Return, subject to the applicable provisions and tax regime.

Salaried employees may also provide the required documents to their employer when requesting appropriate tax treatment for TDS purposes.

Joint Home Loan and the New Tax Regime

The choice between the old and new tax regimes can significantly affect the tax benefits available from a home loan.

Under the new tax regime, Section 80C deductions such as eligible housing-loan principal repayment are generally not available. In addition, interest on borrowed capital for a self-occupied property cannot be claimed as a Section 24(b) deduction under the new regime.

For a qualifying let-out property, the new regime permits deduction of actual interest under Section 24(b), but the resulting house-property loss cannot be set off against other heads of income or carried forward in the same manner as under the old regime.

This makes the tax-regime decision particularly important for homeowners with substantial loan interest.

What About a Second Property?

The tax treatment of a second property depends on factors such as whether it is self-occupied or let out, the applicable tax regime and the other conditions of the Income Tax Act.

Under the old regime, eligible interest deductions under Section 24(b) can apply to qualifying properties, while the treatment of rental income and house-property losses must also be considered.

Section 80C continues to have a combined ₹1.5 lakh individual limit, rather than providing a separate ₹1.5 lakh limit for every home loan or property.

When Can a Co-Borrower Miss Out on the Tax Benefit?

A joint borrower should not assume that being listed on the loan is sufficient.

Potential problems can arise when:

• The person’s name is not on the property ownership documents.
• The person is an owner but is not a borrower on the home loan.
• The person does not actually contribute towards repayment where such contribution is relevant to the claim.
• The required conditions for the particular deduction are not satisfied.
• The taxpayer chooses a tax regime under which the relevant deduction is unavailable.
• The necessary ownership, loan or payment records are not maintained.

The exact tax position can depend on the structure of the transaction, so unusual ownership or repayment arrangements should be reviewed with a qualified tax professional.

Documents to Keep for Joint Home Loan Tax Claims

Maintain copies of:

1. Home loan interest certificate
2. Home loan agreement
3. Sale deed or other ownership documents
4. Documents showing the ownership arrangement
5. Bank statements showing EMI payments
6. Possession or completion-related documents, where applicable
7. Receipts for eligible stamp duty and registration charges
8. Relevant tax and income records

Keeping these documents together can make it easier to support the deduction if the tax authorities require clarification.

What If the Ownership Shares Are Unequal?

Consider a hypothetical example where one co-owner has a 70% ownership interest and the other has 30%.

Instead of automatically assuming a 50:50 tax claim, the ownership documents, loan arrangement and actual repayment contribution should be examined together.

The important point is consistency. If the ownership structure, EMI contributions and tax claims do not match the underlying arrangement, the taxpayers may face questions about the deduction being claimed.

For this reason, it is better to establish the ownership and repayment structure clearly when purchasing the property rather than trying to reconstruct it while filing the ITR.

Should You Take a Joint Home Loan Only for Tax Benefits?

Tax savings can be useful, but they should not be the only reason for taking a joint home loan.

Before adding a co-borrower, consider:

• Combined repayment capacity
• Credit profiles of both applicants
• Ownership rights
• EMI contribution
• Future sale or transfer of the property
• Applicable tax regime
• Long-term financial responsibilities

A joint loan can provide financing and tax advantages when the ownership, borrowing and repayment structure genuinely support them. It should be planned as part of the overall property and financial arrangement.
