You signed the booking form. Your home loan is running. The builder is working floor by floor. And every month, you are paying Pre-EMI interest - but you cannot claim a single rupee of tax deduction yet.
That is the under-construction property tax dilemma - and it confuses thousands of borrowers every year.
Here is the truth:
The tax benefits on an under-construction home loan are real and very significant.
You just cannot claim them during construction. The rules are specific - and understanding them before possession can save you from costly mistakes and missed deductions that run into lakhs of rupees.
This guide explains every tax benefit available on home loans for under-construction properties in 2026 - Section 24(b), Section 80C, Section 80EEA, the pre-construction interest rule, the 5-year possession deadline, and exactly what happens if you sell the property early.
The Golden Rule: No Deductions During Construction
Before anything else, this is the single most important rule to understand:
Deductions under Section 24(b) on home loan interest payments cannot be claimed during construction. These deductions are available only after the property is completed and possession is taken.
The under-construction period, also known as the pre-possession phase, refers to the duration from the initiation of a home loan until the construction is finished or possession is obtained.
You cannot immediately deduct the loan interest you pay during this time.
This means: even if you are paying ₹40,000 per month in Pre-EMI interest for 3 years during construction, none of it is deductible in those years. The clock on your deductions starts only from the year of possession.
But - and this is the crucial part - that Pre-EMI interest is not lost. It is preserved and claimable in instalments after possession. Let us first see how income taxes are calculated on a home loan as per the new and old tax regimes.
Tax on Home Loans As Per Old Regime
Tax on Home Loans As Per the New Regime
Now, let us see the home tax benefits in detail.
Benefit 1: Section 24(b) - Interest Deduction After Possession
Under Section 24(b) of the Income Tax Act, you can claim a deduction on the interest paid on your home loan after you take possession of the property.
For self-occupied property: You can claim up to ₹2 lakh per financial year as deduction on home loan interest (under the old tax regime). This is one of the most valuable benefits for homeowners.
For let-out (rented) or deemed let-out property: There is no upper limit on the interest you can deduct while computing “Income from House Property”.
Important: The deduction is available only after possession. You must also be the registered owner of the property. For self-occupied homes, the ₹2 lakh limit applies only if construction is completed within the prescribed timeline (explained later in this article).
Once you receive possession, you can claim up to ₹2 lakh per year on the interest you pay on your outstanding home loan - every year until the loan is repaid.
For a borrower in the 30% tax bracket, this single deduction saves ₹60,000 in tax annually. Over a 15-year remaining tenure, that is ₹9 lakh in total tax savings from this one section alone.
For let-out (rented) property: There is no upper limit on home loan interest deduction under Section 24(b) when calculating Income from House Property. You can deduct the entire interest paid during the year.
However, if the interest exceeds your rental income and creates a loss from house property, this loss can be set off against your other income (salary, business, etc.) only up to ₹2 lakh per year. Any excess loss can be carried forward for up to 8 assessment years (generally to be set off only against future house property income).
Benefit 2: The Pre-Construction Interest Deduction - The Rule Most Borrowers Miss
This is the most valuable and most misunderstood tax rule for under-construction property buyers.
For under-construction properties, the interest paid during the pre-construction period can be claimed as a deduction over five equal instalments, starting from the year the construction is completed.
2.1: How does it work?
Step 1: Add up all the interest you paid from the day of your first loan disbursement until the last day of the financial year before the year of possession. This total is called your Pre-Construction Interest (PCI).
Step 2: Divide this total by 5.
Step 3: Claim this 1/5th amount every year for 5 years - starting from the year of possession - in addition to the regular annual interest deduction.
Example
Year
EMI Paid
Pre-EMI Interest
Taxable?
2022–23 (Year of Loan)
Pre-EMI only
₹1,20,000
No - accumulates
2023–24
Pre-EMI only
₹1,40,000
No - accumulates
2024–25
Pre-EMI only
₹1,60,000
No - accumulates
2025–26 (Possession Year)
Full EMI starts
Total PCI = ₹4,20,000
Claim ₹84,000/year for 5 years
2.2: The Combined Annual Deduction After Possession
The total claim - current year interest plus 1/5th of pre-construction interest - is still capped at ₹2 lakh for self-occupied homes.
Component
Annual Deduction
Current year interest paid
₹1,60,000
1/5th of Pre-Construction Interest (₹4,20,000 ÷ 5)
₹84,000
Combined before cap
₹2,44,000
Applied cap under Section 24(b)
₹2,00,000 maximum
Even with the cap, you are still maximising the full ₹2 lakh deduction every year - and the pre-construction interest ensures you reach that cap comfortably.
Benefit 3: Section 80C - Principal, Stamp Duty, and Registration
Section 80C allows a deduction of up to ₹1.5 lakh on the principal repayment of home loans for under-construction properties. It further allows the borrower to avail of a tax deduction on the payments made towards stamp duty and registration charges only after the construction of the property is complete.
Since the under-construction stage of the house is well-defined and no principal amount is owed during this period, the eligibility for claiming tax benefits under Section 80C does not occur during construction. The under-construction period concludes only when full EMI payments commence. Later, the principal amount becomes claimable under Section 80C.
3.1: What qualifies under Section 80C after possession
Principal component of each EMI - up to ₹1.5 lakh per year
Stamp duty paid at the time of registration
Property registration charges
Important: The ₹1.5 lakh limit under Section 80C is shared among other tax-saving instruments like PPF, ELSS, life insurance premiums, etc. Prioritise home loan principal repayment within your Section 80C investments to maximise tax benefits.
This means if you are already investing ₹1 lakh in PPF and ELSS combined, your home loan principal deduction only gives you ₹50,000 more under Section 80C - not the full ₹1.5 lakh. Plan your 80C portfolio accordingly.
Benefit 4: Section 80EEA - Additional Deduction for Affordable Housing
If the stamp duty of the property purchased does not exceed ₹45 lakh under Section 80EEA, you can also avail of a tax deduction of up to ₹1.5 lakh on the interest payment of home loans for under-construction properties.
If you took a loan for an affordable property before March 31, 2022 and still meet the conditions, you can continue claiming this deduction in FY 2026-27 for the interest paid during the year. The maximum combined benefit then becomes: ₹2,00,000 (Section 24b) + ₹1,50,000 (Section 80EEA) = ₹3,50,000 on interest alone.
4.1: Conditions for Section 80EEA
Loan must have been sanctioned between April 1, 2019 and March 31, 2022
The stamp duty value of the property must not exceed ₹45 lakh
You must not be eligible for deduction under Section 80EE
You must be an individual (not a company or HUF)
You must not own any other residential property on the date of loan sanction
For eligible borrowers who took loans in the 2019–2022 window, this deduction continues to apply in FY 2026-27 on the interest paid - provided all conditions are met.

The Critical 5-Year Possession Rule
This rule applies specifically to self-occupied properties:
If construction is not completed and possession is not taken within 5 years from the end of the financial year in which you took the home loan, the maximum interest deduction under Section 24(b) drops from ₹2 lakh to just ₹30,000 per year.
Example:
Loan taken in August 2021: 5-year deadline ends on 31 March 2027.
If you get possession by 31 March 2027: Full ₹2 lakh limit applies.
If possession is delayed beyond this date: Your annual interest deduction for self-occupied property reduces to only ₹30,000 (a big loss of ₹1.7 lakh in deduction every year).
Note for let-out properties: The above reduction to ₹30,000 does not apply. You can still claim the full interest deduction (subject to the loss set-off rules mentioned earlier).
What to do if your builder is delaying
Document all communication demanding possession
Approach RERA for the state where the project is registered
Apply for an extension or compensation under RERA provisions
Inform your tax consultant so you can plan for the reduced deduction scenario if necessary
Note: If the delay is due to court orders, government actions, or circumstances beyond the builder's control, some tax authorities have provided relief - consult a Chartered Accountant for your specific situation.
The 5-Year Sale Rule - Tax Benefits Are Reversible
If you sell off your property within 5 years from the last day of the financial year in which you gained possession, all these tax benefits will be reversed.
If you sell within 5 years of possession, all Section 80C deductions claimed previously will be added back to your income and taxed in the year of sale. Section 24(b) interest deductions are not reversed even if the house is sold early.
If you took possession in March 2025 and sell in December 2027 (within 5 years of possession):
All principal deductions claimed under Section 80C from 2025 onwards are added back to your taxable income in FY 2027-28
Stamp duty and registration charge deductions claimed under 80C are also reversed
Interest deductions under Section 24(b) are NOT reversed - you keep those
This reversal can result in a large unexpected tax bill in the year of sale. Plan holding period carefully before deciding to sell.
Joint Ownership - Double the Tax Benefits
If a home loan is taken jointly, each co-borrower who is also a co-owner of the property can claim deductions independently.
Both co-borrowers who are also co-owners can independently claim full deductions - ₹2 lakh each under Section 24(b) and ₹1.5 lakh each under Section 80C.
Both must be co-owners on the property documents AND co-borrowers on the loan agreement.
If one person is just a co-applicant (on the loan) but not on the property title, they cannot claim independent deductions.
What About The New Tax Regime?
As of 2026, the New Tax Regime is the default. Under the old regime: includes 80C, 24(b), and 80EEA - usually better if total deductions exceed ₹4 lakh. Under the new regime: no 80C or 24(b) for self-occupied houses - only interest on let-out properties is allowed, capped at rental income.
Should you choose the old or the new regime as an under-construction property buyer?
If your total eligible deductions - home loan interest (₹2 lakh) + principal (₹1.5 lakh) + other 80C investments (PPF, ELSS, LIC) - exceed ₹4 lakh per year, the old tax regime almost always saves you more tax. Run both calculations with your actual numbers or use an online home loan tax benefit calculator before deciding.
Documents Required to Claim Tax Benefits
You need a completion or possession certificate to confirm the 5-year construction condition, co-ownership documents if claiming as joint borrowers, stamp duty and registration receipts if claiming those under 80C, and the interest certificate from your lender.
The complete document checklist are as follows.
For claiming Section 24(b) interest
Annual interest certificate from your lender (bank or HFC)
Possession certificate or completion certificate from the builder
Registered sale deed or allotment letter
For claiming pre-construction interest
Year-wise interest certificates covering the entire pre-possession period
Loan disbursement schedule showing dates and amounts
Builder's completion certificate confirming the year of possession
For claiming Section 80C principal + stamp duty
Annual interest certificate (shows principal component separately)
Stamp duty payment receipt
Property registration receipt
Possession certificate
For Section 80EEA (if applicable)
Loan sanction letter dated between April 1, 2019 and March 31, 2022
Proof that the stamp duty value of the property does not exceed ₹45 lakh
Self-declaration that no other residential property is owned at the time of sanction
How to Claim These Deductions in Your ITR
When you file your return by the ITR filing deadline of July 31, 2026, Section 24(b) interest is entered under "Income from House Property" - a negative value for self-occupied property shows as a loss. Section 80C principal is entered under Chapter VI-A deductions.
Summary
Home loan tax benefits for under-construction property in 2026 are powerful - but require careful understanding of timing, rules, and limits. Here is the complete recap:
No deductions during construction. Pre-EMI interest paid before possession is not immediately deductible - it accumulates.
Pre-construction interest claimable in 5 equal instalments starting from the year of possession - even if the accumulated amount is large.
Section 24(b): Up to ₹2 lakh per year on interest after possession - combined with 1/5th PCI, subject to the ₹2 lakh cap.
Section 80C: Up to ₹1.5 lakh per year on principal repayment, stamp duty, and registration - available only after possession.
Section 80EEA: Additional ₹1.5 lakh interest deduction for eligible affordable housing loans sanctioned by March 2022 - still claimable in FY 2026-27.
5-year possession rule: Construction must be complete within 5 years of the end of the loan-taken FY - or the Section 24(b) limit drops to ₹30,000.
5-year sale rule: Selling within 5 years of possession reverses all Section 80C deductions claimed - plan your exit timeline accordingly.
Joint ownership: Doubles all deductions for couples who are both co-owners and co-borrowers.
Old vs New Tax Regime: All deductions are available only under the old tax regime - calculate carefully before choosing your regime.
