Reassessment and business-use tests: vague material fails for reopening, while actual commercial occupation shields a flat from wealth-tax.

Reassessment requires tangible material with a rational nexus to a bona fide belief that income escaped assessment; a vague Inspector's report was insufficient, so the reassessment was quashed. Service of notice under section 148 was nevertheless treated as established because the assessee accepted the notice in conduct and participated in proceedings. For house-property and wealth-tax purposes, occupation of the Mumbai flat for business use was the material test, and evidence of business activity supported depreciation, maintenance claims, and exclusion from wealth-tax. For the later period when business use had ceased, only fair notional rent under section 23 could be brought to tax, limited to the rateable value basis.

Issues: (i) Whether the reassessment proceedings were validly initiated. (ii) Whether service of notice under section 148 of the Income-tax Act was established. (iii) Whether the Mumbai flat was used for business purposes so as to allow depreciation and maintenance charges and to exclude the property from wealth-tax. (iv) Whether notional rent could be charged for the period when the flat was admittedly not used for business purposes.

Issue (i): Whether the reassessment proceedings were validly initiated.

Analysis: Reassessment can be initiated only where there is material having a rational connection with the formation of a bona fide belief that income chargeable to tax has escaped assessment. Mere suspicion or a vague report does not suffice. The Inspector's report only showed that the flat was locked on the date of visit and that someone came once a month for cleaning, but it did not establish that the property had not been used for business in the relevant earlier years. The material relied upon by the Assessing Officer was thus too general and was later undermined by the earlier appellate decision for the related assessment year.

Conclusion: The reassessment proceedings were invalid and were quashed, in favour of the assessee.

Issue (ii): Whether service of notice under section 148 of the Income-tax Act was established.

Analysis: Although service of notice is a condition for reassessment, the assessee addressed a letter stating that the original returns may be treated as returns filed in response to the notice. That conduct amounted to acceptance of service in the facts of the case, and the assessee also participated in the reassessment proceedings.

Conclusion: The objection to service of notice failed and the issue was decided in favour of the Revenue.

Issue (iii): Whether the Mumbai flat was used for business purposes so as to allow depreciation and maintenance charges and to exclude the property from wealth-tax.

Analysis: Section 22 of the Income-tax Act and section 2(ea)(3) of the Wealth-tax Act exclude property occupied for business or profession. The statutory language does not require the premises to be a commercial property; occupation for business use is the material test. The record showed business expenditure, bank operations, client confirmations, and other evidence supporting use of the flat for business activities. The society's description of the building as residential was not decisive.

Conclusion: The flat was held to have been used for business purposes, the depreciation and maintenance claims were allowable, and the flat was not liable to wealth-tax on that basis, in favour of the assessee.

Issue (iv): Whether notional rent could be charged for the period when the flat was admittedly not used for business purposes.

Analysis: For the period during which the assessee had stopped using the premises for business, the property could be brought to tax only on a fair rental basis under section 23. The addition had to be aligned with the available municipal rateable value evidence, and no further material justified a higher figure.

Conclusion: Notional rent was sustained only to the limited extent of the proportionate amount directed, resulting in a mixed outcome, partly in favour of the assessee and partly in favour of the Revenue.

Final Conclusion: The reassessment challenges succeeded, the business-use claim in respect of the flat was accepted, the wealth-tax additions were deleted, and only a limited notional rent addition survived for the later period in the relevant year.

Ratio Decidendi: Reassessment requires tangible, relevant material connecting the belief of escapement to the assessment year, and property actually occupied for business use is outside the charging provisions for house property income and wealth-tax even if situated in a residential complex.
