Sub-clause (b) of section 24 read with the second proviso, and section 26 of the Income-tax Act, 1961 -- the per-co-owner ₹2 lakh cap; the requirement of definite and ascertainable shares; the contribution-based allocation; the practitioner's structuring of joint title plus joint loan plus joint EMI; and the Income Tax Appellate Tribunal jurisprudence on partial-EMI and single-EMI joint-ownership scenarios
Taxpayer Brief
Where a husband and wife jointly own a residential property and have jointly taken the home loan, each spouse can independently claim the section 24(b) interest deduction up to ₹2 lakh -- producing an aggregate family deduction of ₹4 lakh. The effective tax saving on a ₹4 lakh deduction at the 30%-plus-cess slab is approximately ₹1.25 lakh per year. Maximising this is one of the most lucrative tax-planning levers available to dual-income salaried families. The conditions are precise -- joint title with definite shares, joint loan, contribution-based EMI payment, separate documentation. This article maps the framework, the common structures, the partial-payment contingencies, and the practitioner's checklist.
Complexity Matrix
Feature | Complexity Level | Primary Risk |
|---|---|---|
Joint title 50:50, joint loan, joint EMI 50:50 | Low | Each spouse claims ₹2 lakh; aggregate ₹4 lakh |
Joint title 50:50, joint loan, single-spouse EMI | Medium | Income Tax Appellate Tribunal authority required for full claim by EMI-payer |
Unequal joint title (e.g., 70:30), joint loan, allocation by share | High | Section 24(b) follows ownership share; documentation critical |
Joint title with parents / siblings; multiple co-owners | Very High | Per-owner ₹2 lakh; aggregate up to ₹6L+; complex contribution mapping |
1. The Statutory Framework
Provision | Effect |
|---|---|
Section 26 of the Income-tax Act, 1961 | Where property is owned by two or more persons and their respective shares are definite and ascertainable, each co-owner is taxed individually on the portion of income attributable to his / her share |
Sub-clause (b) of section 24 | Interest on loan for property is deductible from House Property income; capped at ₹2 lakh for self-occupied property |
Second proviso to sub-clause (b) of section 24 | The ₹2 lakh cap applies per assessee (per co-owner), not per property |
The ₹2 lakh cap is per assessee, not per property This is the critical statutory point. Where a property is jointly owned by two persons (typically spouses), the ₹2 lakh cap is available to EACH of them separately. A property with joint title and joint loan can therefore support a combined ₹4 lakh interest deduction at the family level. With three co-owners, ₹6 lakh; with four, ₹8 lakh. Each co-owner files his / her own Income Tax Return claiming his / her own share of the deduction. |
2. The Three Conditions for the Per-Co-Owner Claim
Condition | Test | Documentation |
|---|---|---|
1. Joint Title with Definite Shares | Sale deed registers each co-owner's specific percentage share -- e.g., 50:50, 70:30, 25:25:25:25 | Sale deed; share-of-ownership clause |
2. Joint Loan | Both / all co-owners are co-borrowers on the loan agreement | Loan sanction letter; loan agreement |
3. Contribution-Based EMI Payment | Each co-owner pays his / her share of the EMI, ideally from his / her own bank account | Bank statement showing EMI debits by each spouse / co-owner |
Case Law Reference: Mumbai Income Tax Appellate Tribunal -- partial-EMI scenarios Where the EMI is paid wholly from one spouse's account but both are co-owners and co-borrowers, the Mumbai Bench has accepted the full deduction by the EMI-paying spouse subject to documentary support of the inter-spouse arrangement (gift, contribution, or family-financing agreement). The Bench has not allowed the non-EMI-paying spouse to claim a deduction not actually paid. The cleanest structure remains contribution-based EMI -- each spouse paying his / her own share.

3. Worked Example -- Dual-Income Couple in Bangalore
Mr. Vikram (₹35 lakh annual salary) and Mrs. Asha (₹30 lakh annual salary) jointly purchased a 3 BHK apartment in Bangalore for ₹1.5 crore in April 2023. Both are 50:50 co-owners. Joint home loan of ₹1.2 crore at 8.5% annual interest; EMI ₹1,04,000 per month, paid 50:50 from each spouse's salary account. Annual interest in Tax Year 2026-27 (year 4 of the loan) -- approximately ₹9.6 lakh.
Per-Spouse Computation | Mr. Vikram | Mrs. Asha |
|---|---|---|
Share of total interest paid -- 50% of ₹9.6 lakh | ₹4,80,000 | ₹4,80,000 |
Section 24(b) cap for self-occupied property | ₹2,00,000 | ₹2,00,000 |
Allowable section 24(b) deduction | ₹2,00,000 | ₹2,00,000 |
Tax saved at 30% slab + 4% Cess (each spouse) | ₹62,400 | ₹62,400 |
Combined family tax saving | ₹1,24,800 | (same) |
Without joint structure -- single-owner alternative Had Mr. Vikram alone been the title-holder and sole borrower, his deduction would have been capped at ₹2 lakh -- and the additional ₹2.8 lakh of interest paid (his share of ₹4.8 lakh minus the ₹2 lakh cap) would have been wasted from a tax perspective. The joint structure preserves the full benefit. The structuring decision must be made at the time of purchase -- joint title cannot be retrofitted to convert single-owned property to joint without triggering section 56(2)(x) gift implications. |
4. Unequal Share Scenario
Where the joint title shows unequal shares (e.g., 70:30 between spouses), the section 24(b) deduction must be allocated in the same ratio. Each co-owner can claim up to ₹2 lakh, BUT only on his / her share of the actual interest. If the 30%-share spouse's allocated interest is only ₹1.5 lakh, that is the ceiling of his / her claim -- the unused ₹50,000 of the ₹2 lakh cap cannot be transferred to the other spouse.
5. Multi-Co-Owner Structures
Co-Owner Profile | Aggregate Section 24(b) Cap |
|---|---|
2 co-owners (typical spouse case) | ₹4 lakh |
3 co-owners (parent + spouse + self) | ₹6 lakh |
4 co-owners (parent + spouse + self + sibling) | ₹8 lakh |
Hindu Undivided Family co-ownership with members | Per-member cap; HUF as single owner has its own ₹2 lakh |
The 4+ co-owner caveat Bringing in additional co-owners beyond the spouse pair (parents, siblings, adult children) to inflate the aggregate cap can be structured but invites scrutiny. The assessing officer can challenge whether the additional co-owners genuinely contributed to the purchase consideration and EMI payments. Each additional co-owner should have demonstrable funds-flow evidence supporting their share. Without genuine funds, the co-ownership is a façade. |
6. Section 80EEA / 80EE Layer
The additional ₹50,000 deduction under section 80EE (for first-time buyers, sanction in 2016-17) and the additional ₹1.5 lakh deduction under section 80EEA (for affordable housing, sanction in 2019-20 to 2022-23) are also per-assessee deductions and can be claimed independently by each co-owner subject to the eligibility conditions. HP-09 covers the section 80EEA framework in detail.
7. Practitioner Documentation Discipline
- Sale deed clearly recording each co-owner's percentage share.
- Loan sanction letter naming all co-borrowers.
- Loan agreement -- shareholder-wise interest schedule.
- Bank statement showing EMI debits from each spouse's / co-owner's separate account.
- Annual interest certificate from the lender, ideally with each co-borrower's share separately certified.
- Internal contribution agreement if EMI is paid disproportionate to ownership share -- explaining the contribution arrangement.
- Each co-owner's Income Tax Return claiming his / her share of section 24(b) deduction.
8. Key Takeaways
- Section 26 read with second proviso to section 24(b) -- the ₹2 lakh cap is per co-owner, not per property.
- Three conditions -- joint title with definite shares, joint loan, contribution-based EMI.
- Spouse pair structure produces ₹4 lakh aggregate deduction; family tax saving roughly ₹1.25 lakh per year.
- Mumbai Income Tax Appellate Tribunal accepts partial-EMI scenarios with documentary support of inter-spouse contribution.
- Multi-co-owner structures (3+) can scale aggregate cap; require genuine funds evidence per co-owner.
- Sections 80EE / 80EEA provide additional per-assessee deductions; co-owners can claim independently.
