SARS Releases Updated VAT Modernisation Consultation Paper: What Businesses Need to Know

SARS has just published the follow up to its 2023 VAT Modernisation Discussion Paper, and it’s a meaningful step forward. The new VAT Modernisation Consultation Paper, published in August 2026, takes the feedback SARS gathered during that earlier consultation and turns it into something far more concrete: a more defined operating model, clearer technical direction, and a detailed, proposed implementation timeline.

This isn’t a new idea appearing out of nowhere. It’s the next chapter in a process SARS started three years ago. For businesses, that means the “wait and see” phase is coming to an end. Below are the main highlights of the paper, and what businesses can start doing about it today.

SARS’s Vision for VAT Modernisation

SARS’s bold vision is a future where tax compliance “just happens”: instead of businesses gathering VAT data after the fact to prepare a return, VAT compliance becomes something that’s built into everyday business activity, with data flowing to SARS as transactions occur.

The benefits SARS points to aren’t only about making life easier for the tax authority. For taxpayers, the paper talks about less compliance effort, fewer errors, faster VAT refunds, and real time visibility into VAT liabilities and compliance status. For the economy more broadly, SARS is targeting a smaller VAT collection gap, reduced fraud, easier trading conditions, and closer alignment with the digital VAT systems already used internationally.

The Proposed Model: A Five Corner Digital VAT Ecosystem

At the heart of the paper is what SARS calls the Digital VAT Model, a Decentralised Continuous Transaction Control and Exchange model built around five “corners”:

• Corner 1 (C1), the Supplier or Issuer: Passes invoice data from their accounting or ERP system to their Supplier Access Point
• Corner 2 (C2), the Supplier’s Access Point: An accredited service provider that validates and clears that e-invoice, and transmits it to both the buyer’s and SARS’s access points
• Corner 3 (C3), the Buyer’s Access Point: Captures the e-invoice sent from the Supplier’s Access point and in turn, transmits it to the buyer’s internal systems
• Corner 4 (C4), the Buyer or Recipient: Receives the cleared e-invoice to be captured internally.
• Corner 5 (C5), SARS’s Access Point: Receives the e-invoice data for risk analysis, pre filled returns, and eventually auto assessment.

The important thing to notice here is that this is a decentralised model. Businesses won’t be sending invoices directly to SARS. Instead, everything flows through accredited service providers who handle the validation, clearance and routing. That design avoids a single point of failure, and it also means SARS doesn’t need to build a direct integration with every single business in the country. The service providers carry that load.

One detail worth flagging early: An e-invoice under this model is not a PDF or a scanned document. It needs to be a structured, machine readable file that follows a prescribed data standard. If your business is exclusively issuing invoices as PDFs or emailed documents, that’s already a sign of where the gap will be.

The Implementation Timeline

SARS has set out five broad phases stretching over roughly six years:

1. Phase 1, Preparation (2026/2027, about 12 months): Stakeholder consultation, readiness assessments, and draft regulations.
2. Phase 2, Solution Development (2027/2028, about 12 months): Finalising technical standards and the regulatory framework.
3. Phase 3, Validation and QA Testing (2028/2029, about 6 months): Controlled testing with voluntary participants.
4. Phase 4, Pilot (2029/2030, about 6 months): Onboard pilot participants and execute voluntary pilot.
5. Phase 5, Phased Implementation (from 2030, about 36 months): Staged rollout, starting with large B2B business, then B2G, then MSMEs, then B2C businesses.

What This Means For Your Business

Chapter 9 of the paper goes into detail about exactly where the impact will be felt, and it’s worth reading closely:

• IT environments: Accounting and ERP systems need to be able to support the issuing and receipt of structured e-invoices, connect securely to accredited service providers, and handle data exchange in near real time.
• Tax and finance processes: The shift moves tax teams away from periodic, month-end VAT preparation and toward continuous transaction reporting. Instead of doing the calculations themselves, teams will spend more time managing data quality and dealing with exceptions the system flags in real time.
• Organisational readiness: SARS expects change management, staff training, and project teams that bring together IT, finance and compliance people to manage the transition properly.
• Large businesses: Generally in a good position, since most already run modern ERP or accounting software. The work here is more about integration and adjusting processes than replacing systems entirely.
• MSMEs: Face a bigger climb, particularly those still relying on paper, spreadsheets, or static PDF invoices. SARS has acknowledged this and is planning provide guidance and support channels to assist with this transition.

Wherever your business sits in this picture, the message is the same: data quality and system design are now part of your compliance obligations, not just an operational nice to have.

What Businesses Can Do Now

You don’t have to wait for final regulations before you start preparing. A few practical steps worth taking today:

1. Audit your master data. Look for missing VAT numbers, outdated or incorrect tax codes, and inconsistent customer or supplier records. Structured e-invoicing will have no tolerance for the small data gaps that manual processes have quietly absorbed for years.
2. Build controls into how documents are generated. Your systems shouldn’t allow an invoice to be created with missing mandatory fields, a duplicated invoice number, or the wrong VAT treatment. Fixing this now improves your compliance today, not just when the new framework arrives.
3. Check your systems readiness. Speak to local e-invoicing service providers about whether your current ERP or accounting environment can support structured data exchange, and whether you require any fixes or updates.
4. Automate your AR and AP processes now. Implementing e-invoicing ready accounts receivable and payable automation brings real commercial benefits straight away: faster collections, fewer manual errors, and better visibility of cash flow, all while putting you ahead of the compliance curve when the framework becomes mandatory.

Final Word

This Consultation Paper shows that SARS’s VAT modernisation journey is moving from concept to concrete design. SARS is accepting feedback submissions until 16 October 2026, and there’s a genuine opportunity for businesses, software vendors and industry bodies to help shape the final data model and the regulations that follow.

At VAT Modernisation SA, we help businesses become ready, from data audits through to selecting and implementing the right e-invoicing solution. If you’re not sure where your systems currently stand, now is a good time to find out.
