The amount paid on earnings via Cuelinks account is classified as 'Commission' liable to tax deduction at source, under section 194H of the Income-tax Act, 1961. When tax is deducted at source, Form 16A is provided for the amount of tax deducted. However, in the absence of PAN details, tax is deducted at the rate of 20.6% and we cannot provide you Form 16A to claim credit of tax deducted. Hence, it is advisable to always quote your PAN in your account.
