South Africa’s VAT system is entering a new era.

In August 2026, SARS published its Consultation Paper on VAT Modernisation: E-Invoicing, Interoperability Framework and E-Reporting, setting out a proposed framework that could fundamentally change the way businesses manage VAT.

The vision is ambitious: instead of VAT compliance being something businesses largely deal with at the end of a tax period, SARS wants compliance to become embedded into the ordinary flow of business transactions.

In SARS’s words, the long-term objective is for tax to effectively “just happen”.

From periodic VAT returns to continuous compliance

The current VAT system is largely retrospective. Businesses issue invoices, record transactions, reconcile their accounting records and ultimately submit a VAT201 return.

SARS generally sees the VAT information after the transaction has taken place and the return has been submitted. This can lead to reconciliations, verifications and audits after the fact.

The proposed Digital VAT Model changes that approach.

SARS envisages a system where transactional information can move between businesses, service providers and SARS in near real time.

The three key building blocks are:

• e-Invoicing
• An Interoperability Framework (IF)
• e-Reporting

Together, these form what SARS calls a Decentralised Continuous Transaction Control and Exchange (DCTCE) model.

What is an e-Invoice?

An e-Invoice isn’t simply a PDF invoice emailed to a customer.

Under the proposed model, an e-Invoice is a structured, machine-readable tax invoice containing standardised information that can be automatically processed by accounting and ERP systems.

This distinction is important.

A PDF may be digital in the everyday sense, but it isn’t necessarily structured data that another system can automatically interpret, validate and process.

What will change for businesses?

Businesses will increasingly need their accounting, invoicing and ERP systems to communicate with the digital VAT ecosystem.

That could mean:

• upgrading existing accounting software;
• integrating ERP systems with accredited service providers;
• changing invoice processes;
• improving the quality of customer and supplier data;
• automating VAT validations;
• strengthening internal controls; and
• training finance and IT teams.

For larger businesses, SARS anticipates that adoption may largely involve upgrading existing systems rather than replacing them entirely. Smaller businesses may eventually be able to use service-provider portals or simplified digital tools.

Does this mean VAT returns will disappear?

Not immediately.

The proposed model is intended to provide SARS with trusted transactional information that can eventually be used to pre-fill VAT returns and, over time, support VAT auto-assessment.

Importantly, SARS says taxpayers will retain the ability to review, confirm or amend the outcome, preserving the self-assessment principle.

When will this happen?

This is where businesses need to distinguish between the proposal and the final implementation.

The Consultation Paper envisages:

• preparation during 2026/27;
• solution development during 2027/28;
• testing during 2028/29;
• a pilot during 2029/30; and
• phased implementation commencing during 2030 and extending over approximately three years.

The exact sequencing may still change.

What should businesses do now?

There is no need to panic – but there is a very good reason to start preparing.

Businesses should consider:

1. Review your accounting system.

Can it issue and receive structured electronic invoices?

2. Review your data quality.

Poor customer, supplier and VAT data will become increasingly problematic in an automated environment.

3. Talk to your software provider.

Ask what their roadmap is for South Africa’s proposed e-Invoicing framework.

4. Review your processes.

VAT compliance will increasingly become an ongoing process rather than a month-end exercise.

5. Get finance and IT talking.

VAT modernisation isn’t purely a tax project. It is simultaneously a finance, technology and operational project.

The most important message is that VAT modernisation is not simply a new way of submitting a VAT return.

It is a proposed re-engineering of the VAT ecosystem itself.

Businesses that start preparing now will be in a much stronger position when the transition eventually moves from consultation to implementation.

The Digital VAT Model remains a proposed framework and is subject to consultation, legislative development and further guidance from SARS.
