Section 23 of the Income-tax Act, 2025 — Arrears of Rent and Unrealised Rent Received Subsequently

In plain language

What Section 23 actually deals with

Section 23 of the Income-tax Act, 2025 taxes two specific types of money a landlord receives late — that is, in a year after the rent was originally due:

• Arrears of rent — rent that was legitimately due in an earlier year (say the tenant paid less than the agreed rent, or a rent revision was awarded later) and is received now.
• Unrealised rent — rent that fell due earlier, could not be recovered from a defaulting tenant, and is realised (recovered) subsequently.

The core rule is simple: this money is deemed to be "Income from House Property" in the tax year in which it is received or realised — not the year it was originally due. This is a pure receipt-based (cash) charge grafted onto an otherwise accrual-based head of income.

The three sub-sections in plain English

• Sub-section (1): Arrears of rent received, or unrealised rent realised later, are deemed income from house property in the year of receipt/realisation.
• Sub-section (2): This amount is taxed under "Income from House Property" whether or not you still own the property in that year. So even if you have already sold the house, gifted it, or the tenancy is long over, the recovered rent is still taxed in your hands.
• Sub-section (3): A flat 30% deduction is allowed on the arrears/unrealised rent. Nothing else is deductible against this amount.

Who it applies to

It applies to any assessee (individual, HUF, firm, company) who earlier owned a house property that was let out and who now recovers old rent. The most important feature is that ownership in the year of receipt is irrelevant. If the property has changed hands, the person who is entitled to and actually receives the arrears is taxed.

Key conditions and limits

• The charge is triggered only on receipt — mere accrual or a court decree that is not yet paid does not attract tax under this section.
• The only deduction is 30% of the gross arrears/unrealised rent. You cannot claim municipal taxes, home-loan interest, or actual repair costs against this income — those belong to the regular computation under Section 22/24.
• There is no requirement that the amount was earlier offered to tax or earlier allowed as a deduction. Recovery is taxed on a standalone basis.
• If part of the recovery is interest or damages (not rent), that portion is generally not "rent" and may fall under "Income from Other Sources" instead.

How it interacts with related sections

Section 23 sits inside Chapter IV-C (Income from House Property) of the 2025 Act. It is the successor to Section 25A of the Income-tax Act, 1961, with the language modernised — "financial year" becomes "tax year" and the word "special" is dropped from the heading. The 30% here mirrors the 30% standard deduction on Annual Value under Section 24(a)-equivalent for normal let-out property, keeping the two treatments consistent. Because arrears are pulled out and taxed separately in the year of receipt, they do not get re-added to the Annual Value of the property in the current year.

Practical implications for taxpayers

• Report the recovery in the year the cheque/transfer actually comes in, under Schedule HP of the ITR.
• Do not try to claim interest or municipal taxes against it — only the automatic 30% applies.
• Keep proof (rent agreement, ledger, court order, bank credit) showing the amount is old rent, to justify the 30% deduction and the head of income.
• Even if you no longer file under "House Property" for any current property, a single arrears recovery obliges you to open Schedule HP for that year.
