E-Invoicing in South Sudan: SSRA eTax B2B Requirements

South Sudan’s SSRA eTax platform provides a B2B e-invoice function for registered business accounts. Businesses need a valid Taxpayer Identification Number (TIN) and an eTax business account to create B2B e-invoices for sales or purchases; the platform also supports invoices to registered taxpayers, international or unregistered businesses, and retail or cash-sales transactions.

South Sudan does not currently have a confirmed nationwide structured e-invoicing or real-time invoice-clearance mandate in the official material reviewed. However, the SSRA eTax B2B invoice manual states that valid eTax B2B invoices are required as supporting documents for B2B bank transactions and movements of funds under a Bank of South Sudan directive. The 2024 South Sudan Revenue Authority Act also provides for an Electronic Tax Registrar for businesses, although no technical rollout rules or go-live schedule were identified.

Latest news

South Sudan’s digital tax infrastructure includes the SSRA eTax platform, an official B2B e-invoice verification tool and a published eTax B2B invoice manual. The manual confirms that registered entities can generate B2B e-invoices through eTax at no charge and verify issued invoices using the invoice number.

The 2024 revised South Sudan Revenue Authority Act strengthens the legal basis for electronic revenue administration. It requires revenue collections to be remitted through the government e-Tax system and provides for the deployment of an Electronic Tax Registrar for businesses to monitor and generate sales tax. This supports tax digitisation, but it is not the same as a published mandate requiring all businesses to exchange structured e-invoices in a specified data format.

What is e-Invoicing and why is South Sudan adopting it?

In South Sudan, an e-invoice is a digital invoice created through the SSRA eTax portal. The official eTax manual states that the invoice captures payable taxes when it is created, is accessible to both the selling and purchasing parties, and can be verified through its QR code or invoice number.

This government-issued invoice is a digital tax document, but official materials do not confirm that it must be exchanged in a standard machine-readable syntax such as UBL, XML, Peppol BIS Billing or UN/CEFACT CII. Businesses should, therefore, distinguish between an electronically generated eTax invoice and a regulated structured e-invoice framework.

The evolution of e-Invoicing in South Sudan

South Sudan’s e-invoicing development is closely connected to the broader rollout of digital tax administration:

• 2009: The Taxation Act established the country’s tax framework, including taxpayer registration, record-keeping, sales tax, tax returns, assessments and penalties.
• 2021: The revised Taxation Act confirmed taxpayers’ obligations to keep transaction accounts and supporting records for six years.
• 2022: The Authority published the eTax B2B e-Invoice Training Manual, covering invoice creation, verification and monthly tax declarations. It uses the former NRA name; the Authority is now the SSRA.
• 2024: The revised South Sudan Revenue Authority Act confirmed the Authority’s use of eTax for government revenue collection and its role in deploying an Electronic Tax Registrar to monitor and generate sales tax.

The official record shows an active digital tax and B2B invoice environment. It does not, based on the material reviewed, provide a confirmed effective date for a universal structured e-invoicing mandate.

B2G electronic Invoicing in South Sudan

No separate nationwide B2G e-invoicing mandate could be verified from the official sources reviewed. The SSRA Act does require government tax and non-tax revenue collections to be handled through commercial banks or financial institutions via the eTax system, and it requires banks to generate invoices for customers paying for government services.

Businesses supplying government entities should verify the payment document, tax and procurement requirements stated in the specific contract or tender documentation.

B2B electronic Invoicing in South Sudan

B2B e-invoicing in South Sudan is managed through the SSRA eTax portal. Businesses need a valid TIN and eTax business account to issue B2B e-invoices for sales or purchases. For registered buyers, eTax retrieves the recipient’s details using the TIN, sends a notification, and makes the invoice accessible to both parties. B2B invoices also feed into monthly tax declarations.

The NRA manual states that B2B transactions and bank fund movements must be accompanied by a valid eTax B2B e-invoice under a Bank of South Sudan directive. However, South Sudan has not confirmed a mandatory structured e-invoicing format such as XML, UBL or Peppol, nor a universal tax-authority clearance or real-time reporting requirement. eTax supports invoice-item bulk uploads using an SSRA template.

B2C electronic Invoicing in South Sudan

South Sudan’s eTax invoice workflow includes a retail/cash sales option for sales that cannot be linked to one purchaser. This option can be used for cumulative retail or similar sales, and the eTax manual notes that such invoices may support bank deposits of cash accumulated from sales. That feature should not be treated as evidence of a universal B2C e-invoicing mandate.

The 2024 SSRA Act refers to the deployment of an electronic tax registrar for businesses to monitor and generate sales tax. Businesses should monitor official implementing rules for any future device, registration, invoice-generation or transmission requirements.

E-reporting and sales tax compliance

South Sudan has periodic electronic tax reporting through the SSRA eTax portal, where taxpayers can file declarations for the relevant month, quarter or year using their TIN. The country applies sales tax rather than a general VAT system, covering goods produced in South Sudan, imported goods, and specified services. Businesses liable to pay tax, file returns or withhold tax must register with the SSRA and use their TIN on required returns, transactions, and documents.

B2B e-invoices generated through eTax feed into monthly tax declarations. Businesses must select the correct tax period when issuing an invoice, as invoices created for a past period may lead to penalties during return filing. Taxpayers must keep transaction accounts and supporting documents for six years and make them available for inspection in South Sudan.

What happens if businesses don’t comply?

No standalone e-invoicing penalty is confirmed in the official material reviewed. However, poor records or missing documentation may lead to a tax assessment, and the South Sudan Revenue Authority (SSRA) may inspect documents, books and records and conduct audits. 

Tax understatement penalties under the Taxation Act include:

For unpaid tax, interest accrues at the applicable annual rate. A 5% penalty begins on the first day of the fourth month after the month in which payment was due and is calculated on the first day of each successive month until the obligation is fulfilled.

Where a bank applies the controls described in the eTax B2B e-Invoice Training Manual, a missing or invalid eTax B2B e-invoice may prevent or delay processing of a deposit, withdrawal or international transfer.

Preparing for e‑Invoicing in South Sudan

DDD Invoices helps software providers, ERPs, and platforms manage e-invoicing through one unified API. Instead of building and maintaining separate country-specific invoicing workflows, developers send standard invoice data in JSON while DDD Invoices handles the relevant local format, validation, and delivery workflow.

For South Sudan, this means businesses can integrate eTax-related B2B invoicing processes into their existing systems while keeping invoice data, tax periods, and transaction records organized. As SSRA requirements develop, DDD Invoices can help businesses adapt their invoicing workflows without rebuilding their integration from scratch.
