The Mauritanian Ministry of Finance, through the General Tax Administration, has introduced a new requirement for public institutions to use an electronic invoicing platform, STT, for tax declarations and payments. This mandate, effective November 1, 2026, aims to digitize financial and tax administration, promoting transparency and traceability. The platform will enable institutions to electronically declare taxes, pay fees, and make source deductions.
The STT platform will cover the entire invoicing and payment cycle. Suppliers must declare invoices to public institutions via STT before the institutions review, verify, and electronically approve them. Public institutions are prohibited from paying invoices not registered on the platform by suppliers and electronically approved by the concerned institutions. This measure ensures that all transactions are tracked and recorded electronically.
Public institutions issuing invoices to clients must declare these invoices via the STT platform. After making payments, institutions must electronically record the payment transactions, allowing for complete tracking of invoices from declaration to payment. The Ministry of Finance views this as a step towards a digital, interconnected financial and tax system, reducing reliance on paper documents and enhancing monitoring and data accuracy.
The Ministry of Finance has stated that the new requirement aligns with its efforts to establish a digital financial and tax system. This system aims to minimize paper-based procedures, improve oversight, and provide more accurate data on financial and commercial operations related to the public sector. By implementing this electronic invoicing platform, the government seeks to increase efficiency and transparency in public financial management.
To ensure a smooth transition, the General Tax Administration will organize training and technical support sessions for responsible employees in October. These sessions will cover the use of electronic declaration and payment functions, as well as invoice management via the STT platform. The goal is to guarantee that concerned institutions are prepared for the mandatory application starting November 1, 2026.
The introduction of the STT platform represents an additional phase in the digital transformation of tax administration in Mauritania. By unifying declaration, invoicing, and payment processes within a single electronic space, the government aims to enhance transparency and effectiveness in fulfilling public institutions' financial obligations. This move is expected to improve the overall efficiency of public financial management.
The Ministry of Finance has emphasized that this new requirement is part of its broader strategy to modernize and digitalize public financial management. The successful implementation of the STT platform will depend on the readiness of public institutions and their ability to adapt to the new electronic system. The government is committed to providing necessary support to ensure a seamless transition.
