Insurance commission deduction requirement mandates tax withholding when credited or paid to resident payees under the new provision. A withholding obligation requires any person paying remuneration or reward to a resident for soliciting or procuring insurance business to deduct income-tax at the rates in force at the time of credit to the payee's account or at the time of payment, whichever is earlier, covering commission and related remuneration; a proviso excludes deduction for amounts credited or paid before a specified cut-off date.
