Section 43B of the Income Tax Act

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).

A proviso inserted into a section to remedy unintended consequences, make the section workable, or supply an obvious omission must be read retrospectively in operation to give effect to the section as a whole.

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.

Employee contributions to provident fund or ESI, even if deposited after the due date specified in the respective welfare statutes, are allowable as a deduction under Section 36(1)(va) if paid before the due date for filing the income-tax return. This judgment aligns the treatment of employee contributions with employer contributions under Section 43B.

Tax liability for an item of income or expenditure is determined solely by the provisions of the Income-tax Act. Entries in an assessee's books of account are not conclusive and do not govern the taxability or deductibility of an item, as the legal rights and obligations under the Act prevail.

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.

Employees' contributions to provident fund or other welfare funds are deductible under section 36(1)(va) only if paid by the due date specified in the respective welfare fund enactments, and section 43B does not extend this period to the income tax return filing due date under section 139(1).

Employee contributions to provident fund, ESI, and other welfare funds, if deposited by the due date for furnishing the return of income under Section 139(1), are allowable as a deduction and cannot be disallowed under Section 36(1)(va) read with Section 2(24)(x) or Section 43B, even if deposited after the due date prescribed by the respective welfare Acts.
