E-Invoicing in South Africa: What SARS Is Planning and When It Affects You

What SARS has published so far

SARS published a discussion paper on VAT modernisation in September 2023. On 17 August 2026 it followed up with the Consultation Paper on VAT Modernisation, which covers e-invoicing, an "interoperability framework" for sending invoices between businesses, and e-reporting to SARS. Comments closed on 16 October 2026.

It's a consultation paper, not a law. The paper says its proposals may change after stakeholder input and any legislative process, and the detailed rules are meant to come later as VAT regulations, published in draft first. Until then, nothing about how you invoice has changed. SARS's VAT 404 guide already allows electronic tax invoices, and you don't need SARS's approval to email them.

What counts as an e-invoice

This is the part most people get wrong. In the paper, an e-invoice is a structured, machine-readable tax invoice, built on a prescribed data model, that one accounting system sends and another reads automatically. The paper says plainly that it "is not merely a PDF, scanned image or emailed document."

So the PDF you email a client today is an electronic invoice, but it isn't an e-invoice in SARS's sense. An e-invoice is data. Your VAT number, your client's, every line and the VAT all sit in fixed fields that software can check.

The paper doesn't choose a format yet. It names EN 16931, UN/CEFACT's Cross-Industry Invoice and Peppol PINT BIS as examples of the kind of standard e-invoices would have to follow. Credit notes and debit notes would be covered as well.

How it would work

SARS proposes what it calls a five-corner model:

1. You, the supplier, issue the e-invoice from your accounting software.
2. Your service provider, an "access point" accredited by a new Network Authority, checks it against the technical standard and the VAT rules. If it passes, it's sent on. If it fails, it comes back to you to fix.
3. Your client's service provider checks it again and delivers it.
4. Your client's system receives it and replies, including whether they're claiming the VAT on it.
5. SARS's service provider receives the VAT data from both sides.

All of this happens in near real time, as invoices are issued. Today SARS only sees your figures when your VAT201 comes in, and checks them afterwards. You and your client would each pick your own service provider from a list the Network Authority publishes.

The end goal is a VAT201 that SARS pre-fills from your invoices and you confirm or correct. SARS calls the final stage VAT auto-assessment, and describes it as tax that "just happens".

When it's planned to happen

Slowly. The paper sets out five phases:

• Preparation in 2026/27, about 12 months: consultation with industry and draft VAT regulations.
• Building the system in 2027/28, about 12 months: standards and specifications, and the final regulations.
• Testing in 2028/29, about 6 months, with volunteers.
• A pilot in 2029/30, about 6 months, with volunteers from priority sectors.
• A phased rollout starting in the 2030 calendar year and running for about 36 months.

The rollout is split by type of business. Large businesses go first, and sales to government may come in at the same time. Micro, small and medium businesses follow, and the paper expects their adoption to be gradual "over several years". Sales to consumers and to businesses that aren't VAT registered come last. Large businesses are expected to join voluntarily before it becomes compulsory for them, and a business of any size can volunteer. SARS adds that the order may still change.

What it means for a small business

Nothing is required of you today. If the timeline holds, nothing becomes compulsory for anyone before 2030, and small businesses come after the large ones. The direction is clear, though. The paper says small businesses will need to "gradually move away from paper-based, spreadsheets or emailed PDF invoices" to accounting software or a service provider's portal.

A few habits will make that move easier whenever it comes:

• Get your tax invoices right now. An e-invoice is checked against the VAT rules before it's delivered, so a missing VAT number or a wrong heading would be sent back instead of slipping through. Our tax invoice checklist covers every field.
• Keep your clients' details accurate, especially their VAT numbers. You can confirm a VAT number for free on SARS's VAT Vendor Search, and our guide to checking a VAT number shows how.
• Move off Word and Excel templates. Invoices kept in software as data can be converted later. A folder of Word files is much harder to bring along.
• Number your invoices and credit notes in clean sequences, and keep them for five years, as you already have to.

On cost, the paper accepts that businesses will have to spend on software and setup, and says SARS will talk to software providers about tiered pricing and "subsidised or low-cost options" for smaller taxpayers. Nothing has been decided.

If you aren't VAT registered, you're at the back of the queue. The last phase covers sales to consumers and non-registered businesses, and the paper only says that incentives "may be considered" there.

Doing this in Invo

Invo keeps every invoice as data rather than as a document: your details, your client's VAT number, each line with its VAT treatment (standard, zero-rated or exempt), the totals and the sequence number. The PDF your client receives is generated from that. It isn't an e-invoice in SARS's sense, and there's nothing to connect one to yet, because SARS hasn't chosen the standard or accredited any service providers. What Invo does now is make sure the tax invoice itself is right, which is what an e-invoice will be checked against. See how invoicing works, or start on the free plan.
