Mauritania e-Invoicing Overview
B2B
none
No official instrument requires electronic invoicing or invoice reporting between private businesses. The Ministry of Finance circular 071-26 of 29 September 2026 concerns public entities only: from 1 November 2026, those that invoice their own clients must declare those outgoing invoices on the STT platform, but the text says nothing about invoices exchanged between private companies.
B2G
planned
From 1 November 2026, every public entity must require its suppliers of goods, works and services to declare beforehand on the Système de Télédéclaration et de Télépaiement (STT) the invoices addressed to it, under circular 071-26 of the Minister of Finance . The public entity checks and validates each invoice in its own STT space. From that date no invoice subject to the procedure may be paid unless the supplier declared it and the client entity validated it on the platform, and after payment the entity records the payment there. The same circular makes STT the exclusive channel for public entities' tax returns and payments. The circular also provides for the Direction Générale des Impôts to run training throughout October 2026 for the entities concerned, covering electronic filing, electronic payment and electronic invoice management on STT.

Under circular 071-26 , posted by the Ministry of Finance on 30 September 2026 , the scheme runs on new features that the Ministry introduced, through the Direction Générale des Impôts, in the Système de Télédéclaration et de Télépaiement (STT). The supplier declares the invoice on STT, the public client reviews and validates it in its STT space, and the entity records the payment after settlement. Validation is done by the buying entity, not by the tax administration. The circular gives no technical specification, data format or schema, and does not say whether the declared invoice replaces the paper invoice or accompanies it.
