Own a Second House You Don't Rent Out? The Taxman Still Adds Notional Rent to Your Income (2026)

Buy a second house to keep for aging parents, a future move, or simply as an investment, and leave it vacant — no tenant, no rent, no rental agreement — and it feels reasonable to assume the property generates no taxable income at all. The Income Tax Act takes a different view. Once a taxpayer owns more than two residential houses, any additional one that isn't actually let out is still taxed as though it were, under a rule the law calls 'deemed to be let out.'

The Two-House Rule Budget 2019 Introduced

Until FY 2019-20, only one self-occupied house could carry a nil annual value for tax purposes — a second self-occupied property was automatically treated as let out, even if nobody lived there and no rent changed hands. Budget 2019 raised that limit to two, a change aimed squarely at taxpayers who own a home in their native town and a second one near their workplace, using both without renting either out. Both stay at nil annual value under this rule, and it applies whether you file under the old or the new regime — our guide to claiming HRA and home loan interest together covers a closely related scenario for taxpayers in exactly this position.

The Third House Onward: Section 23(4) and Notional Rent

A third residential property — or any beyond the first two — that is neither actually let out nor used for business falls under Section 23(4) and is deemed to be let out. The law then computes a notional, or expected, rent for it under Section 23(1)(a): the higher of the municipal valuation and the fair rent for a comparable property in the same area, capped at the standard rent if the property falls under rent-control legislation. This expected rent is added to taxable income under 'Income from House Property' exactly as if a tenant were actually paying it — even if the house sat locked and empty all year.

What You Can Deduct Against the Notional Rent

The notional rent isn't taxed in full. A flat 30% standard deduction under Section 24(a) applies regardless of actual maintenance spend, and home loan interest on that specific property is deductible under Section 24(b) if it was purchased or built with a loan. Unlike a self-occupied property, there's no ₹2 lakh ceiling on the interest claimed against a deemed let-out house — the cap only bites if the resulting loss is set off against other income, where Section 71(3A) limits that set-off to ₹2 lakh a year, with the remainder carried forward for eight assessment years. Our breakdown of the ₹2 lakh set-off cap under Section 24(b) covers exactly how that carry-forward works.

A Worked Example

Consider someone who owns a flat they live in, a second house in their hometown kept for parents, and a third apartment bought as an investment that currently sits vacant. The first two qualify as self-occupied under the 2019 rule and carry nil annual value. The third, deemed let out, is assessed on its expected rent — say, a locality where comparable flats fetch ₹18,000 a month, or ₹2,16,000 a year. After the flat 30% standard deduction (₹64,800), taxable income from that one unrented flat works out to ₹1,51,200, taxed at the owner's slab rate, even though not a single rupee of actual rent was ever collected.

How to Avoid Getting Caught Out at Return-Filing Time

• Count every residential property you own, jointly or individually — co-owned houses can complicate which two qualify as self-occupied.
• If a third house sits vacant, estimate its notional rent using the municipal valuation or a broker's rent estimate for comparable properties, rather than assuming it adds nothing to your return.
• Choosing which two houses to nominate as self-occupied is generally the taxpayer's own call each year — nominate the ones with the lower notional rent, since any additional houses default to the deemed-let-out calculation.
• If the third property has a home loan, keep interest certificates ready — the Section 24(b) deduction against notional rent is claimed the same way as it would be for an actually rented property.

Owning more real estate than you can occupy or rent out is common enough — an inherited house, a second home bought early, or a flat kept for a child's future. None of that makes the notional rent optional. The safer approach is to estimate it before filing, using a same-locality rent comparison, rather than discovering the gap only after a scrutiny notice flags a house that never showed up on the return.
