Buying Before March 31? Home Loan Tax Benefits Explained

The last quarter of the financial year concentrates property decisions, because buyers want deductions to land in the current assessment year rather than the next. Understanding home loan tax benefits before March 31 helps you judge whether the rush is worth it — or whether a calmer purchase in April serves you better.

The two principal deductions

Under the old tax regime, two provisions matter most to homebuyers.

The Section 24 home loan interest deduction allows interest on a housing loan to be claimed against income, subject to the applicable annual limit for a self-occupied property, with different treatment for a let-out property. Section 80C principal repayment allows the principal portion of your EMI, along with stamp duty and registration paid in the year of purchase, to be claimed within the overall 80C limit.

Both are claimed on a payment basis within the financial year, which is why the March 31 deadline matters. Availability also depends on which tax regime you have opted for, so confirm your position with a chartered accountant before making a decision based on tax.

Under-construction property is treated differently

Interest paid during the construction period is not deductible in the year it is paid. It is aggregated and claimed in instalments after the property is completed and possession is taken, under the rules applicable at the time. That single point changes the calculus for any buyer choosing between a near-ready home and one several years from handover.

A phase with possession scheduled for 2027, such as Ramky Fortuna's Phase 1, brings the completion date — and therefore the start of the interest deduction — considerably closer than stock with four-to-five-year timelines. It also brings forward rental income, computed in this corridor at 3.5 to 4.0% of property cost semi-furnished.

Costs you can plan around the year-end

• Stamp duty of about 5% in Karnataka for properties above Rs 45 lakh, with registration and cess taking the total to roughly 6.6 to 7.7%.

• GST of 5% on under-construction consideration.

• Club membership, maintenance corpus and advance maintenance of 12 to 24 months at handover.

Stamp duty and registration are among the items claimed in the year they are paid, which is one reason registration timing gets attention in March.

Do not let the deadline choose the property

A deduction is a percentage of an expense; the property is the whole of it. Buying a weak asset in March for a tax benefit is a poor trade against buying the right one in May. If the year-end pressure is genuine, work backwards: get your loan sanction in place first, keep the documentation ready, and confirm that the developer can complete the agreement and registration within the window.

Then judge the asset on its own terms — rate against the corridor average of about Rs 13,000 per sq. ft., possession date, layout efficiency and the depth of the local rental market — and treat home loan tax benefits before March 31 as a tiebreaker rather than a reason.

A year-end action list

• Confirm which tax regime you are on, since the deductions depend on it.

• Get your loan sanction in place before you shortlist, not after.

• Keep identity, income and address documentation ready for both the lender and the sub-registrar.

• Ask the developer in writing whether the agreement and registration can be completed before 31 March.

• Book the sub-registrar appointment early, as March is the busiest month of the year.

• Speak to your chartered accountant before you commit, not after.

Handled in that order, the deadline becomes a schedule rather than a scramble.
