What SARS Requires on a Tax Invoice (2026)
The seven fields on a full tax invoice, the five on an abridged one, and the VAT thresholds that changed on 1 April 2026. Straight from SARS.
The most expensive invoicing mistake in South Africa is not a missing field: it is a freelancer who has never registered for VAT sending a document with the words "Tax Invoice" across the top.
That is not a formatting slip. Charging VAT you are not registered to charge is money you have collected on SARS's behalf without being entitled to, and it is the kind of thing that gets found retrospectively rather than at the time.
Put a number on it, because that is what makes it real. Invoice R40 000 a month with 15% added that you were never entitled to add, and after a year you are holding R72 000 that was never yours, spent, on a business that turns over less than half a million. That is not a fine. That is the money itself, before anybody talks about penalties.
So this starts with whether you may issue one at all, and then with what actually has to be on it. If you are here to pick a tool rather than to check a document, the ranked guide is the faster read.
First: are you allowed to issue one?
Section 20 of the VAT Act puts the obligation to issue a tax invoice on a registered vendor. Not on a business, not on anyone who sends invoices. On a vendor whose registration SARS has confirmed.
If you are not registered, you send an invoice. Not a tax invoice, and with no VAT on it. The word "tax" in front of "invoice" is a claim about your VAT status, and it should only be there if the claim is true.
The registration thresholds changed on 1 April 2026
Compulsory VAT registration went from R1 million to R2.3 million of taxable supplies a year, and voluntary registration went from R50,000 to R120,000. Almost every article you will find on this subject still quotes the old numbers, so if you read somewhere that you must register at R1 million, that page has not been updated since March. The VAT rate is unchanged at 15%.
What that change means in practice is that a lot of small businesses which were about to cross the old line are no longer anywhere near the new one. If you registered voluntarily to look established, you are now carrying VAT admin that most of your competitors are not.
That is a decision worth revisiting with whoever does your books, and it is separate from the question of what goes on the document. Where the line falls between an invoice tool and a bookkeeping one is its own question, covered in invoicing versus accounting software.
The seven things on a full tax invoice
Required when the supply, Excluding VATThe rate before 15% VAT is added, which is how almost every South African provider quotes. A rate of 2.30% excl. VAT actually bills you 2.645%, so two quotes are only comparable once you know which basis each is on.Why it decides which invoice you oweA job quoted at R4 500 excluding VAT is R5 175 including it. That is over the R5 000 line, so it needs the full seven fields, not the abridged five.Prices in South Africa are quoted both ways and the difference is 15%. It matters here more than anywhere else in invoicing, because SARS measures both tax-invoice thresholds on the amount INCLUDING VAT. Quote your work excluding VAT, check the threshold excluding VAT, and you will issue abridged invoices on supplies that legally required full ones. The R50 floor works the same way.See every term in the glossary, comes to more than R5 000. SARS's own checklist is blunt about the standard: all seven have to be there for the document to be a tax invoice.
The words Tax Invoice, VAT Invoice or Invoice
Any one of the three is accepted. It has to appear on the document.
The one field people assume is decorative. It is the first thing on SARS's list.Your name, address and VAT registration number
The supplier's details, with the VAT number, not just a letterhead.
An address on the logo is not an address on the invoice. A PO box and a trading name are both fine; a missing VAT number is not.Your customer's name and address, and their VAT number if they are a vendor
Their VAT number is only required where the recipient is itself a registered vendor.
This is the field that separates a full invoice from an abridged one, and it is why B2B invoices need more care than retail ones.A serial number and the date of issue
Sequential, unique, and dated. Not the date you were paid.
Reusing or restarting numbers is the single most common finding when somebody's invoicing gets looked at.An accurate description of what you supplied
Specific enough to identify it. Where the goods are second-hand, the checklist requires that to be indicated.
\"Services rendered\" is the line that fails this, and it is on a great many South African invoices.The quantity or volume supplied
How many, or how much. Hours, units, litres, kilograms.
The second field an abridged invoice drops, which is why it feels optional. On anything over R5 000 it is not.The value, the VAT charged, and the total
All three as separate figures: the amount before VAT, the tax, and the consideration.
A single VAT-inclusive total does not satisfy this, and it is what stops your customer claiming the input tax.Two things about that list, because they are where the real errors sit.
The threshold is measured including VAT, so a job quoted at R4 500 plus VAT is R5 175 and needs the full seven. Pricing excluding VAT and checking the threshold excluding VAT is how businesses issue abridged invoices on supplies that required full ones.
And "accurate description" is doing more work than it looks. A line that reads "consulting" tells SARS nothing about what was supplied, and it is the field most likely to be queried on a document that is otherwise perfect.
The abridged version, and what it drops
Where the supply including VAT is more than R50 and less than R5 000, you may issue an abridged tax invoice instead. It needs five of the seven.
What comes off is your customer's details and the quantity. Everything else stays exactly as it was: the words, your name and address and VAT number, the serial number and date, the description, and the value with the VAT shown separately.
The practical read is that an abridged invoice is a retail document. It exists so a shop does not have to collect a customer's address and VAT number to sell them something for R300.
If you invoice businesses, you will almost never use it, and there is no advantage in trying to. Most invoicing software puts the customer on the document by default, which means you are producing full tax invoices without deciding to, and that is the safe direction to be wrong in. The free tools do this as well as the paid ones.
Under R50, and the receipt you still need
If the supply including VAT is R50 or less, no tax invoice is required at all.
That does not mean no document. SARS is explicit that a till slip or sales docket showing the VAT charged is still needed for the input tax to be deducted, which matters to whoever bought from you rather than to you.
So the R50 rule is a relief from issuing an invoice, not a relief from keeping a record. In a business that sells a lot of small items, the till slip is doing the compliance work, which is one of the quieter arguments for a card machine that prints.
There is no such thing as SARS compliant software
Every invoicing tool sold in this country describes itself as SARS compliant, and the phrase does not mean anything.
Compliance is a property of the document, not of the program that printed it. The VAT Act puts seven requirements on a piece of paper. Any tool that lets you put those seven things on it produces a compliant tax invoice, including a spreadsheet, and no tool prevents you from leaving one of them off.
What software genuinely does is narrower and more useful than the marketing claim. It stores your VAT number so it cannot be forgotten. It numbers invoices sequentially so you cannot repeat one. It keeps the value, the VAT and the total as three separate figures rather than one. And it holds your customers' details, so a full invoice is the default rather than something you assemble.
Those are real, and they are worth paying for if you invoice often. They are just not the same claim as "compliant", and a tool that lets you type "services rendered" into the description field, which all of them do, has not made you compliant at all. Our ranked guide covers which ones pre-fill the most of this for you.
What to do with this
If you are not VAT registered, take the word "Tax" off your template today and stop adding 15% to anything. You are under the compulsory threshold until R2.3 million of taxable supplies a year, and voluntary registration now starts at R120 000 rather than R50 000.
If you are registered, open your last invoice over R5 000 and check it against the seven. The two that fail most often are the customer's address and a description specific enough to identify what you sold.
If you have been issuing documents headed "Tax Invoice" without being registered, that is a conversation to have with an accountant rather than something to quietly fix. VAT you charged and were not entitled to charge does not stop existing because the template changed.
And if you are looking at this because you are choosing a tool, choose it on what it does for getting you paid rather than on the compliance claim. The seven fields are the easy part, and every tool in the market can do them.
Questions people actually ask
The document
What must be on a tax invoice in South Africa?
A full tax invoice needs seven things: the words Tax Invoice, VAT Invoice or Invoice; your name, address and VAT registration number; your customer's name and address, plus their VAT number if they are a vendor; a serial number and date of issue; an accurate description of what was supplied; the quantity or volume; and the value, the VAT charged and the total shown separately.All seven are required. Checked against SARS on 4 September 2026.
What is an abridged tax invoice?
A shorter tax invoice permitted where the supply, including VAT, is more than R50 and less than R5,000.It needs five of the seven fields: the words Tax Invoice, VAT Invoice or Invoice; the supplier's name, address and VAT number; a serial number and date; an accurate description; and the value, VAT and total. It drops the customer's details and the quantity supplied.
VAT status
Can I issue a tax invoice if I am not VAT registered?
No. Section 20 of the VAT Act places the obligation to issue a tax invoice on a registered vendor, and you cannot issue one until SARS has confirmed your registration.If you are not registered you issue an ordinary invoice with no VAT on it. Charging VAT without being registered means collecting tax you were not entitled to collect, which is usually discovered afterwards rather than at the time.
When must I register for VAT in South Africa?
Compulsory registration applies once taxable supplies exceed R2.3 million a year, raised from R1 million with effect from 1 April 2026.Voluntary registration starts at R120,000 a year, raised from R50,000 on the same date. The VAT rate is 15%. Most articles on this subject still quote the old thresholds, so check the date on anything you read.
Small amounts
Do I need a tax invoice for something under R50?
No tax invoice is required where the supply including VAT is R50 or less.A document such as a till slip or sales docket showing the VAT charged is still needed, because that is what allows the buyer to deduct the input tax. The relief is from issuing an invoice, not from keeping a record.
Software
Is there SARS compliant invoicing software?
Compliance is a property of the invoice, not of the software.Any tool that lets you put the seven required fields on the document produces a compliant tax invoice, including a spreadsheet, and no tool stops you leaving one off. What good software actually does is store your VAT number, number invoices sequentially, keep the value, VAT and total separate, and hold customer details so a full invoice is the default.
