The Home Buyer's Tax Playbook.

Section 24(b) is the most powerful home loan tax benefit available. It lets you deduct the interest component of your home loan EMI — up to ₹2,00,000 per year for self-occupied property under the old regime.

If you took a home loan of ₹50L at 8.5% interest, your annual interest in year one is roughly ₹4.2L. Under 24(b), you can deduct ₹2L of that — saving you up to ₹62,400 in taxes at the 30% slab (plus 4% cess).

The principal repayment of your home loan qualifies for deduction under Section 80C — but it shares the ₹1,50,000 annual basket with PPF, EPF, ELSS, LIC premiums, tuition fees, NSC, and other instruments. You don't get ₹1.5L extra for home loan principal — you get a slice of the same ₹1.5L everyone else gets.

The stamp duty trap: Most home buyers don't realize that stamp duty and registration charges — which can be 5–7% of property value in metros — qualify for 80C deduction in the year you pay them. On a ₹50L flat in Mumbai, stamp duty alone could be ₹2.5L. But since the 80C limit is ₹1.5L, you'll only get ₹1.5L of that deducted — and only if you haven't used any of the 80C basket elsewhere that year.

Two additional deductions exist for first-time homebuyers — but they come with strict eligibility windows and are available only under the old regime.

Important: If your loan was sanctioned after 31 March 2022, neither 80EE nor 80EEA applies. The government has not announced replacements. First-time buyers in FY 2026-27 get only 24(b) + 80C — no additional bonus. Plan accordingly.

If you and your spouse (or any co-owner) are both co-borrowers on a home loan, each can claim the full 24(b) and 80C deductions separately — up to ₹2L interest + ₹1.5L principal per person. For a couple, that's potentially ₹4L in interest deduction and ₹3L in principal deduction.

But there are three conditions that must ALL be met:

The split is proportional. If both earn and contribute equally, each claims 50% of the interest and principal. If one earns more and pays more EMI, they can claim a higher share — provided the bank records show payments from their respective accounts.

If you took a home loan but construction completed in a later financial year, the interest paid during the construction period is called pre-construction interest. You can claim this — but it's often forgotten or misclaimed.

Pre-construction interest is calculated from the date of borrowing to the date of completion (or 31 March prior to completion, whichever is earlier). This total amount is then divided equally over 5 assessment years starting from the year of completion.

Here's the catch most people miss: for self-occupied property, pre-construction interest deduction is within the ₹2L cap of 24(b). So if your regular annual interest already hits ₹2L, the pre-construction portion gives you zero additional benefit for self-occupied property. It only adds value if your regular interest is below ₹2L — or if the property is let-out.

Here's the trap that catches home buyers off guard every year: if you choose the new tax regime, ALL home loan tax benefits for self-occupied property vanish. Zero deduction under 24(b). Zero under 80C for principal. Zero under 80EE/80EEA.

For let-out property, both regimes allow interest deduction — but that's cold comfort if you're living in your own flat. The new regime's lower slab rates (0% up to ₹4L, 5% on ₹4–8L, 10% on ₹8–12L, etc.) are designed for people without deductions. The moment you have a home loan, the math tilts heavily toward the old regime.
