Section 139(1) of the Income Tax Act

A penalty notice issued under section 274 read with section 271(1)(c) is invalid if it fails to specify whether the penalty proceedings are initiated for concealment of income or for furnishing inaccurate particulars of income. This non-specification vitiates the penalty proceedings.

Employee contributions to PF and ESIC, deposited beyond the due date under the respective Acts but within the due date for filing the income tax return under Section 139(1), are allowable deductions under Section 36(1)(va). Such disallowance cannot be made during processing under Section 143(1).

Employee contributions to provident fund and ESI deposited by an employer beyond the due dates prescribed under the respective special Acts are not allowable as a deduction under section 36(1)(va) of the Income-tax Act, 1961. Such disallowance can be made during processing under section 143(1).

Employees' contributions to welfare funds, such as provident fund, are not allowable as a deduction under section 36(1)(va) if deposited beyond the due date prescribed under the respective welfare statutes, even by a single day. Such delayed deposits are not cured even if made before the income-tax return filing due date.

Appellate authorities can entertain fresh claims or revised computations of income made by an assessee, even if these were not submitted through a revised return of income.

A penalty notice under section 271(1)(c) read with section 274 of the Income Tax Act is invalid if it fails to specify whether the penalty is for concealment of income or for furnishing incorrect particulars of income.

A citizen is free to carry on business within the law, and mere tax planning without a motive to evade taxes through colorable devices is not frowned upon. The liability to taxation, for the purpose of tax treaty application, is a legal situation, not the fiscal fact of actual payment.

Belated remittance of employees' contribution to ESI and PF, even if deposited before the due date for filing the return of income under Section 139(1), is not allowed as a deduction. This disallowance falls under Section 36(1)(va) read with Section 2(24)(x), as Section 43B applies only to employer's contributions.

Co-operative banks are not fundamentally different from co-operative societies, entitling them to claim deductions under Section 80P of the Income Tax Act, 1961, including for interest income treated as business income.

Deduction for employees' contributions to PF and ESIC is allowable under Section 43B if paid before the due date for filing the return under Section 139(1); similarly, delayed deposits of employers' contributions to ESIC and PF are also allowable.
