Section 24(b) Home Loan Interest Guide 2026-27

Home loan interest is the single largest tax shield available to Indian property owners. Here’s how Section 24(b) works, how it stacks with 80C principal, and why the new regime changes the math.

Last updated

What is Section 24(b)?

Section 24(b) of the Income Tax Act, 1961 allows you to deduct the interest component of a home loan EMI from taxable income. For most home-loan borrowers in India, this is the single largest legitimate deduction available — because interest dominates the early EMI years.

Deduction caps (FY 2026-27)

  • Self-occupied property (you live in it): up to ₹2,00,000/year. If your annual interest exceeds ₹2L (common in the first 7-10 years of a ₹40L+ loan), the excess is simply unclaimable — no carry-forward for self-occupied.
  • Let-out property (rented): interest is fully deductible against rental income with no ceiling. But overall property-head loss against other income heads is capped at ₹2 lakh/year (the excess loss carries forward up to 8 years).
  • Under-construction property: interest paid pre-possession can be claimed in 5 equal instalments starting the year of possession, within the ₹2L cap.

How 24(b) stacks with 80C and 80EE/80EEA

A home loan EMI has two parts — principal + interest. Each qualifies for a different section:

  • Principal repayment → Section 80C (up to ₹1.5L, shared with other 80C claims like PPF, ELSS, life insurance).
  • Interest → Section 24(b) (up to ₹2L self-occupied / unlimited against rent).
  • First-time buyer, affordable-housing (80EEA) → additional ₹1.5L interest deduction, if your loan was sanctioned between Apr 2019 and Mar 2022. Now grandfathered — no new sanctions eligible.
  • First-time buyer 80EE → additional ₹50K, loan sanctioned FY 2016-17. Also closed to new applicants.

Worked example — ₹50L home loan, self-occupied

Anjali, 34, takes a ₹50 lakh home loan at 8.5% for 20 years. Her year-1 EMI is ₹43,391, of which ~₹42,000/month goes to interest (₹5,04,000/year in year 1). Her principal repayment is ~₹1,38,000/year.

  • 24(b) claim (interest): min(₹5,04,000, ₹2,00,000) = ₹2,00,000 (she loses ₹3,04,000 of interest as unclaimable ceiling overflow)
  • 80C claim (principal): min(₹1,38,000, ₹1,50,000) = ₹1,38,000
  • Additional 80C items (PPF ₹12K): ₹12,000 fills the remaining 80C room
  • Combined home-loan tax saving at 30% slab: (₹2L + ₹1.38L) × 30% = ₹1,01,400/year

Over a 20-year loan, that's roughly ₹15-20 lakh of tax saved — provided Anjali stays in the old regime.

Why the new regime removes 24(b)

Section 115BAC (the new regime, default from FY 2023-24) exchanges most deductions for flatter slabs. For a home-loan borrower with ₹2L of 24(b) + ₹1.5L of 80C + ₹25K of 80D, the old regime usually wins for incomes between ₹10L and ₹30L. Above ₹40L, the deduction stack shrinks in relative terms and new-regime slabs often edge out old.

The only way to know for sure is to compute both. Every data point we've seen — real taxpayer returns across 50+ scenarios — says: if you have an active home loan, compute both regimes before filing. Use our calculator.

Frequently asked questions

What is the Section 24(b) deduction for FY 2026-27?

Under the old regime, you can deduct up to ₹2,00,000/year of home loan interest for a self-occupied residential property. For a let-out (rented) property, interest is fully deductible against rental income — but a property loss cap of ₹2 lakh still applies against other income heads, with the excess carried forward up to 8 years.

Is 24(b) available in the new tax regime?

For self-occupied property — NO, the new regime removes it. For let-out property — YES, interest is still deductible against rental income under the new regime. If your only property is self-occupied and you have a large home loan, the old regime almost always wins. Run our old-vs-new calculator.

Can I claim both 24(b) interest AND 80C principal on the same home loan?

Yes — they cover different parts of the EMI. 80C covers principal repayment (up to ₹1.5 lakh, combined cap with all other 80C items). 24(b) covers interest (up to ₹2 lakh for self-occupied). A typical ₹50 lakh home loan EMI has both components, and you claim each under its respective section.

What about Section 80EE and 80EEA?

80EE offers up to ₹50,000 additional interest deduction for first-time buyers (loan sanctioned FY 2016-17, now closed to new applicants). 80EEA gave up to ₹1,50,000 extra interest for affordable-housing first-time buyers (loan sanctioned Apr 2019 – Mar 2022). Both were OLD-regime only and are now grandfathered — new loans after the closure windows are not eligible.

Can I claim 24(b) on a pre-construction interest?

Yes. Interest paid during the pre-construction period (from the date of borrowing until the financial year immediately before completion) can be claimed in 5 equal annual instalments starting from the year of possession. The ₹2 lakh annual cap applies to the combined claim (pre-construction instalment + current-year interest).
