South Africa Proposes Five-Corner E-Invoicing Model as Part of VAT Modernisation
The South African Revenue Service (SARS) has opened a public consultation on plans to introduce a new digital VAT model built around structured e-invoicing, near real-time reporting and a decentralised interoperability network.
The VAT Modernisation Consultation Paper, published in August 2026, sets out proposals for a Decentralised Continuous Transaction Control and Exchange (DCTCE) model, which SARS describes as its proposed “Digital VAT Model”.
The consultation report says that South Africa’s envisioned VAT ecosystem is built on three core pillars
1. e-Invoicing
2. An Interoperability Framework (IF) and
3. e-Reporting.
The proposals represent a significant move away from South Africa's existing VAT administration system, which largely relies on VAT returns followed by retrospective verification and audits.
Five-Corner Model Proposed
Under the proposed architecture, South Africa would operate a five-corner model involving the supplier, the buyer, the supplier's and buyers accredited service providers, and a tax authority access point. VAT transaction data would flow securely and in near real time between suppliers, buyers, service providers and SARS.
The model envisages both the supplier's and buyer's service providers reporting information to SARS, creating what the consultation paper describes as a "duplex clearance" process.
In a decentralised model, SARS itself would not validate every invoice directly. Service providers validate invoices, and the data is sent to SARS from both sides of the transition,
Invoices failing the required technical or VAT validation would be rejected and returned for correction.
The paper references standards including EN 16931, UN/CEFACT Cross-Industry Invoice and Peppol PINT BIS as examples of standards that could support the system, although final technical requirements have not yet been determined.
Near Real-Time VAT Data
The authority said this would provide greater visibility over VAT transactions and allow it to move towards exception-based oversight, using transaction data to identify discrepancies, fraud and higher-risk activity.
Over the longer term, SARS intends to use the data to support pre-filled VAT returns and ultimately move towards increasingly automated VAT assessment.
The proposals form part of the wider SARS Modernisation 3.0 programme, which aims to embed tax compliance more closely within businesses' existing ERP, accounting, invoicing and payment systems.
Mandatory Adoption Envisaged
No date has yet been set for mandatory e-invoicing.
Instead, SARS is proposing a multi-stage implementation covering preparation, solution development, testing, a pilot and phased implementation.
Initial industry engagement and preparation is expected to begin during 2026/27 and run for approximately 12 months. The consultation paper says implementation would then progress through a pilot, voluntary adoption and ultimately mandatory adoption, although the sequence for different sectors or taxpayer groups remains subject to consultation.
SARS Commissioner Dr Johnstone Makhubu said the reforms were intended to move South Africa away from a VAT system dependent on manual processes and retrospective verification.
"VAT Modernisation is a major step in reshaping how VAT is administered in South Africa. It seeks to move us from a system that is still too dependent on manual processes and retrospective verification, to one where VAT compliance becomes part of the systems businesses already use every day," he said.
SARS is seeking feedback on areas including the policy and technical design, implementation sequencing, taxpayer and service-provider readiness, costs and risks, governance, standards and safeguards.
Interested stakeholders have until 16 October 2026 to submit written comments.
