if I sold goods to customer in December and he returns goods on 5 Jan. then as date to file return fot Dec period is 20 August,whether I need to pay any tax on that sale amount or not if I issue credit note to customer
hmm sorry I meant to ask I sold goods on 25 Dec but customer returns goods on 5 Jan as return period for December month is 20 Jan what will be the treatment of credit note issued to customer on 5 Jan whether it will be deducted from December sale or not
