Since January 13, 2025, the National Bank of the Republic of Kazakhstan has implemented the transition of payment systems of Kazakhstan and information systems of second-tier banks, as well as other participants in payment systems to the international standard of the ISO 20022 payment message format (hereinafter referred to as the international payment message formats).
In connection with the transition to international payment message formats, changes have been made to the Rules for Making Non–cash Payments and (or) Money Transfers in the territory of the Republic of Kazakhstan, approved by Resolution No. 208 of the Board of the National Bank of the Republic of Kazakhstan dated August 31, 2016 (hereinafter referred to as the Rules for Making Non-cash Payments).
Thus, the new form of payment order for payments to the budget, approved by the Rules for making non-cash payments, contains the columns "Actual payer" and "Sender of money".
According to the Rules, when a legal entity pays payments to the budget, as well as OPV, OPVR, OPV and CO to the GFSS, deductions and (or) contributions to the FSMS for its separate unit, the name of the separate unit of the legal entity for whose obligations the payment is being made is indicated in the column "IIN (BIN)" – his BEAN.
It is also stipulated that when a bailiff pays payments to the budget for the debtor's obligations as part of enforcement proceedings, the last name, first name, patronymic (if any) of the debtor for whom the payment is being made is indicated in the column "Actual payer", as well as in the column "IIN (BIN)" – his IIN.
Accordingly, payments to the budget will be posted to the taxpayer's personal accounts using the IIN/BIN indicated in the "Actual payer" column of the payment order, and in other cases payments to the budget will be posted to the taxpayer's personal accounts using the IIN/BIN indicated in the "Money Sender" column of the payment order.
