Section 234B of the Income Tax Act

Rule 8D, for computing disallowance under Section 14A for expenses related to exempt income, applies from Assessment Year 2008-09 onwards; for prior years, a reasonable disallowance must be made. The disallowance under Section 14A cannot exceed the actual exempt income earned.

Payments for the supply or use of computer software, where there is no transfer of copyright but only a right to use the copyrighted product, are generally considered business profits and not 'royalty' or 'fees for technical services' under the Income Tax Act, 1961 or relevant DTAAs. This principle also applies to transponder fees, which are not taxable as royalty.

When computing deduction under Section 10A, if communication or telecommunication expenses are excluded from export turnover, they must also be excluded from total turnover to maintain consistency and apply the ordinary meaning of 'turnover' in context.

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.

The Assessing Officer loses jurisdiction and the entire reassessment becomes invalid if no addition is made in respect of the income that formed the basis of the reopening. Explanation 3 to Section 147 does not permit assessing other escaped income unless an addition is made for the original income forming the reason to believe.

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.

When the cost of acquisition of a capital asset cannot be determined, the computation mechanism for capital gains fails, and thus no capital gains can be charged. This establishes a broader principle that a charging section cannot operate in the absence of specific machinery provisions for computation.

Expenditure is classified as revenue or capital based on its practical business effect, necessity, or expediency, rather than solely on the juristic classification of rights; an enduring benefit does not automatically make an expenditure capital if it facilitates trading operations or business efficiency.

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.

An employer's delayed remittance of employees' contributions to provident fund (PF) or Employees' State Insurance (ESI) is deductible if the payment is made before the due date for filing the income tax return under section 139(1), applying the provisions of section 43B and notwithstanding section 36(1)(va).
