Section 80AB of the Income Tax Act

When computing deductions under Chapter VI-A, such as Section 80IA, losses from other business undertakings must be set off against the profits of the eligible undertaking before calculating the deduction. No deduction under Section 80IA is permissible if the overall 'Profits & Gains of Business or Profession' results in a loss.

Profits of an eligible undertaking cannot be adjusted against losses from other undertakings when calculating deductions under sections like 80-IA, 80IB, or 80IC. The overriding provisions of these sections require that deductions are calculated based on the profits of the eligible unit itself, without set-off.

Gross total income must be computed by setting off losses, including brought-forward losses and unabsorbed depreciation, before any deductions under Chapter VI-A can be considered. Deductions under Chapter VI-A are only available if the resulting gross total income is positive.

Each industrial undertaking must be considered independently when calculating deductions under Section 80-I of the Income-tax Act, 1961, even if the assessee has multiple units and incurs losses in one unit while making profits in another.

Expenditures such as salary, travelling, and conveyance linked to setting up a new business are revenue in nature and allowable as deductions, especially when some linked expenses (like salary) have already been allowed.

When computing deductions under Section 80HHC, profits from the export of self-manufactured goods and trading goods cannot be considered separately if there is a loss in one, and the deduction is admissible if the overall business income is positive after set-off.
