In a directive issued on Friday, Mr Moun Deng Ajuet said the move is aimed at strengthening transparency, reducing revenue leakages and modernising the country’s revenue administration.
According to the order, “all government revenues must be paid exclusively through the National e-Tax System,” meaning that taxes, levies, duties, penalties, licenses, permits and other government-related payments must now be processed only through the digital platform.
The directive implements provisions of Presidential Order No. 35/2025, which requires the full digitalisation of public revenue collection across government institutions.
Under the new rules, government officials and agencies are prohibited from receiving cash, cheques or any other form of manual payment outside the official system.
“No government official, department, agency or authorised collector is permitted to receive cash, cheque, or any other form of manual payment outside the system,” the order states.
The revenue authority warned that any individual or institution found collecting government payments manually, issuing unofficial receipts or bypassing the electronic system will face administrative penalties, disciplinary action and possible legal consequences in accordance with the law.
Officials say the introduction of the e-Tax platform is part of broader reforms aimed at strengthening financial governance and ensuring public funds are properly accounted for.
The order notes that the digital system will help “improve transparency and accountability in public finance, prevent revenue leakages, enable real-time monitoring of collections, and improve efficiency and convenience for taxpayers.”
Taxpayers and institutions are now required to process all payments through the official platform and obtain electronic receipts generated by the system as proof of payment.
The revenue authority further indicated that inspections and audits will be carried out to ensure compliance with the directive. Authorities said the monitoring process will verify whether institutions and collectors are adhering to the digital payment requirements.
The directive marks one of the most significant steps by the government to modernise revenue collection in South Sudan, where manual tax payments and informal collection practices have historically contributed to weak revenue tracking and financial leakages.
Officials at the revenue authority say the shift to the e-Tax system will strengthen oversight of government income streams while making it easier for taxpayers to comply with payment requirements.
“All stakeholders are required to comply,” the directive states, emphasising that the reform is part of ongoing government efforts to safeguard national resources and improve accountability in public financial management.
