SARS Calls for Comments on a New Digital VAT Model: What It Means for Businesses

SARS is no longer talking about VAT modernisation in the abstract. On 18 August 2026, SAnews reported that the revenue service has asked the public to comment on its VAT Modernisation Consultation Paper, which sets out a proposed Digital VAT Model for South Africa. The paper builds on the 2023 discussion paper and forms part of SARS Modernisation 3.0.

The standard VAT rate stays at 15%. This is a systems and administration reform, not a rate change. The direction is familiar from our earlier note on the SARS VAT modernisation project: less paper, less after-the-fact checking, and more structured data flowing as invoices are issued.

Understanding the Digital VAT Model

Commissioner Dr Johnstone Makhubu framed the shift plainly: South Africa still leans on manual processes and retrospective verification. The proposal is to make VAT compliance part of the systems businesses already use, rather than a separate filing exercise after the month or two-month period closes.

The Consultation Paper groups the model around three building blocks:

• e-Invoicing: a structured, machine-readable tax invoice that can be processed automatically. A PDF or emailed scan is not an e-invoice under this model.
• An Interoperability Framework: a network of service providers that lets suppliers, buyers and SARS exchange validated invoice data securely, without every vendor integrating directly with SARS.
• e-Reporting: near real-time (or just-in-time) transmission of VAT transaction data to SARS as invoices move through the value chain.

SARS describes the end-state as a decentralised continuous transaction control model. Over time, trusted data could support pre-filled returns and, eventually, VAT auto-assessment so that for compliant vendors, tax “just happens” as part of ordinary trading. Implementation is expected in phases: preparation, solution design, testing, a pilot, then voluntary and later mandatory adoption. Sequencing by sector can still change.

Why This Matters for South African Businesses

If you are already a VAT vendor, or you are approaching the R2.3 million compulsory registration threshold, this is the compliance change to watch through 2026 and beyond. SARS says the model should give vendors a simpler, more predictable experience, lower administrative effort, and faster handling of VAT information. For SARS, the prize is clearer visibility of transactions, better fraud detection, and a smaller VAT compliance gap.

The trade-off is that accuracy moves to the point of invoicing. Invoice data, VAT numbers, credit notes and adjustments will need to be right the first time. Accounting and ERP software that cannot produce structured e-invoices, or that still treats VAT as a month-end spreadsheet, will become a business risk rather than a back-office inconvenience.

Small and mid-sized vendors should pay particular attention to cost, readiness and who will act as their access point or service provider. SARS is explicitly asking for evidence-based comment on those points: design choices, sequencing, readiness, costs, risks, benefits, governance, standards and safeguards.

Impact on Consumers and the Broader Economy

Households will not see a new VAT rate from this paper. Zero-rated basics remain a separate policy question. The intended economic gain is cleaner data, less duplicate processing, smoother digital trade between businesses, and a more trusted tax ecosystem. If fraud and the VAT gap shrink, there is less pressure to raise the 15% rate later to fund the same revenue.

The risk is implementation friction. If the model is poorly sequenced, smaller suppliers could face software, training and service-provider costs before the promised admin savings arrive. That is why SARS is stressing a consultative, phased path rather than a single switch-on date.

Preparing for the Consultation and the Rollout

Written comments must be in by 16 October 2026, using the response mechanism in the Consultation Paper. The paper is on the SARS website. If you are a VAT vendor, software provider, accountant or industry body, this is the window to shape the model before it hardens into regulations and technical standards.

1. Read the Consultation Paper and decide whether the three-pillar model is workable for your sector.
2. Ask your accountant or software vendor whether they can support structured e-invoicing, not just PDF invoices.
3. Estimate the cost of changing invoicing, VAT number validation and reporting workflows.
4. Submit practical, evidence-based comments by 16 October 2026 if the proposals affect how you trade.
5. Keep using the current 15% rate correctly in the meantime. The calculator on this site still applies today's rules.
