Q.Mr. Dutta owns a house. He runs his own medical clinic from the ground floor (his professional income from the clinic is separately taxable under 'Profits and Gains of Business or Profession') and lives with his family on the first floor. Explain, with reference to Section 22, how the ground-floor clinic portion is treated for the purposes of the head 'Income from House Property'.

A property portion an owner uses for their own taxable business or profession is carved out of this head entirely, not merely given a deduction after being included.

Only the first-floor residential portion (if let out) or the fact that it is self-occupied would be relevant to this head; the clinic portion is not.

Section 22 charges to tax the Annual Value of a building EXCEPT such portions as the assessee occupies for a business or profession of their own, the profits of which are chargeable to tax. Mr. Dutta occupies the ground floor for his own medical practice, and his professional income from that clinic is already taxable under the separate head 'Profits and Gains of Business or Profession'. Bringing the same floor's notional Annual Value into 'Income from House Property' as well would, in substance, tax the economic benefit of that space twice over — once as part of his professional profits (through the deduction he would otherwise NOT get for a notional rent on his own premises) and once again as house-property income. Section 22's own carve-out avoids this by excluding the clinic portion from this head at the very first step, not merely allowing a deduction for it afterward. The first-floor residential portion, being genuinely occupied for personal residence and not for any taxable business/profession, remains within the scope of this head and would be assessed as a self-occupied house under Section 23(2) if Mr. Dutta owns no other residential house.

A common error is trying to bring the business-use portion into the house-property computation and then look for a deduction to cancel it out — the correct treatment is to exclude that portion from this head from the very first step, under Section 22 itself, not to include and then offset it.
