Section 34 of the Income-tax Act, 1961 outlines the conditions under which depreciation can be claimed as a deduction. This section specifies that depreciation is allowable only if the prescribed conditions are met, including the use of the asset for business or profession and ownership by the assessee. The section also mandates that the asset must be put to use during the relevant previous year. The significance of this section lies in its role in ensuring that only genuine claims for depreciation are allowed, thereby preventing tax evasion through inflated depreciation claims. The burden of proof lies with the taxpayer to demonstrate compliance with these conditions. In practice, this section is crucial for businesses as it directly impacts the computation of taxable income by allowing deductions for the wear and tear of assets.
