You can make an advance payment specifically towards your immediate next tax return by choosing the required option under the "Advance Payment" section of the "My Payments" screen. Your immediate next tax return will be displayed in the “Payment towards your next tax return filing” field. This advance payment will be held on account until your immediate next tax return is filed. Any excess amount after the settlement of the said tax return will then be used to settle any other outstanding or future liabilities strictly on the basis of due dates starting with the oldest liability first.
Note that, for example, if your tax period is monthly and you file your December return first and then try to make an advance payment, the tax period listed in the "Payment towards your next tax return filing" field would be the subsequent period (i.e. January) and not the one you just filed (i.e. December). Your advance payment would then be held on account till that subsequent period’s return (i.e. January) is filed and will not be allocated to the December tax return that was just filed. The payment for the December return that you have already filed, would need to be made from the “Select and Pay” screen and not as an advance payment.
Note that if you wish to make an advance payment via GIBAN, you must first generate a unique payment reference number in EmaraTax.
