How to Register for VAT in South Africa (2026): R2.3m Threshold, Efiling VAT101 & 21‑day Rule

Understanding how to register for VAT in South Africa is now more important than ever following the significant threshold changes introduced in the 2026 National Budget. From 1 April 2026, the compulsory VAT registration threshold increased from R1 million to R2.3 million in taxable supplies over any consecutive twelve-month period, while the voluntary registration threshold rose from R50,000 to R120,000. These changes have created both opportunities and compliance obligations for thousands of businesses, particularly SMEs deciding whether to register, remain registered, or deregister. This guide provides a complete, step-by-step walkthrough of the SARS eFiling VAT101 application process, the documents you need, the critical 21‑day application deadline, and practical decisions every business owner must consider in 2026.

Quick Answer, Do You Need to Register for VAT in South Africa in 2026?

If your business makes taxable supplies exceeding R2.3 million in any consecutive twelve-month period, you are legally required to register for VAT with the South African Revenue Service (SARS). You must submit your application within 21 days of the date on which you exceeded the threshold. Businesses with taxable turnover above R120,000 but below R2.3 million may choose to register voluntarily. Both thresholds took effect on 1 April 2026, replacing the previous R1 million (compulsory) and R50,000 (voluntary) limits.

If you have already exceeded the R2.3 million threshold and have not yet applied, act immediately, late registration can trigger penalties, interest, and retrospective VAT liability on transactions conducted while unregistered.

Key Definitions, Taxable Supplies, “Person” and When the Threshold Applies

What Counts as Taxable Supplies?

Under the Value-Added Tax Act 89 of 1991, taxable supplies include all goods and services supplied in the course or furtherance of an enterprise that are subject to VAT at the standard rate (currently 15%) or the zero rate. Exempt supplies, such as certain financial services, residential accommodation, and public transport, are excluded from the threshold calculation. Only a “person” carrying on an “enterprise” can register, and the VAT Act defines “person” broadly to include individuals, companies, close corporations, trusts, partnerships, and public authorities.

Measuring Turnover, the Rolling 12‑Month Period

The threshold is not measured against your financial year. Instead, SARS applies a rolling consecutive twelve-month test: at any point during the year, you must assess whether your total taxable supplies over the preceding twelve months have exceeded R2.3 million. This means a seasonal business that concentrates sales in a few months can trigger the threshold even though its annual financial statements show lower overall revenue.

Example 1: A sole proprietor consulting firm invoices R200,000 per month. By month twelve, cumulative taxable supplies reach R2.4 million, triggering the compulsory registration obligation.

Example 2: A trading company sells goods worth R1.8 million over twelve months, with only R1.5 million qualifying as taxable supplies (the balance being exempt financial services). It remains below the R2.3 million threshold and is not obliged to register, though it may voluntarily do so if taxable supplies exceed R120,000.

2026 Threshold Changes Explained, R2.3m Compulsory and R120k Voluntary

Effective Date and Transitional Rules

The compulsory registration threshold of R2.3 million and the voluntary registration threshold of R120,000 both apply from 1 April 2026. The increased thresholds were announced in the 2026 National Budget and confirmed by SARS in its Budget 2026 Frequently Asked Questions. For businesses that exceeded the previous R1 million threshold before 1 April 2026, the obligation to register under the old rules remains, the new threshold does not retroactively remove an existing registration obligation that arose before the effective date.

Voluntary Registration Changes

A business may now voluntarily register for VAT if its taxable supplies exceeded R120,000 in the past twelve months. Voluntary registration is commonly used by start-ups and SMEs that want to recover input VAT on business expenses, such as equipment purchases, professional fees, and premises costs, before reaching the compulsory threshold. However, voluntary registration also brings filing obligations: you must submit VAT returns on time and charge VAT on all taxable supplies, which can affect pricing competitiveness if your customers are not VAT-registered.

Step-by-Step: How to Register for VAT in South Africa Online via SARS eFiling (VAT101)

SARS offers two primary channels for VAT registration: the SARS eFiling portal (online) and a virtual appointment booked through the SARS eBooking system. The eFiling route is the most commonly used and is described in detail below. Alternatively, you may engage a registered tax practitioner to submit on your behalf.

Starting on eFiling, Prerequisites

Before you begin the SARS VAT registration online process, ensure you have the following in place:

• Active SARS eFiling profile. If you do not have one, register at www.sarsefiling.co.za using your tax reference number.
• Organisation linked to your profile. For companies, close corporations and trusts, the entity must be registered with SARS for income tax and linked to the eFiling profile of the representative taxpayer or public officer.
• All supporting documents scanned and saved as PDF files. SARS requires clear, legible digital copies, photographs of documents are frequently rejected.
• Valid contact details. SARS communicates application status updates via email and SMS; outdated contact information causes avoidable delays.

Completing Form VAT101, Field-Level Tips

The core application for VAT registration is the VAT101 form, which you complete directly in the eFiling portal. SARS also publishes the VAT-REG-02-G01 Guide for Completion of VAT Application (available as a downloadable PDF) which provides field-by-field instructions. Follow these numbered steps:

1. Log in to SARS eFiling and select your organisation.
2. Navigate to SARS Registered Details → My Tax Products → select VAT.
3. Select “Add new product registration” and choose VAT101.
4. Complete all mandatory fields:
   • Business activity description and SIC code
   • Expected annual turnover from taxable supplies
   • Requested effective date of registration (this is the date your VAT obligations begin, typically the first day of the month in which you exceeded the threshold)
   • VAT accounting basis, choose between the invoice basis (standard) or payments basis (available only if annual taxable supplies do not exceed R2.5 million)
   • Tax period preference, monthly (Category A) or bi-monthly (Category B), depending on expected turnover and SARS assignment
   • Banking details for any refunds
   • Public officer / representative taxpayer information
5. Review the declaration carefully. Incorrect information, particularly mismatched entity names or banking details, is the most common cause of rejection.

Uploading and Naming Documents

After completing the VAT101 form fields, you will be prompted to upload supporting documents. Use clear file names (e.g., COR14.3_CompanyName.pdf, BankLetter_CompanyName.pdf) and ensure each file is under 5 MB. Required formats are typically PDF. SARS may reject blurry scans, screenshots of banking apps, or photographs taken at angles. A full list of required documents appears in the next section.

What Happens After Submission, Processing Stages

Once submitted, your application moves through several stages:

1. Receipt acknowledgement. SARS generates a reference number, save this for future correspondence.
2. Document verification. A SARS official reviews submitted documents for completeness and accuracy. If anything is missing or unclear, SARS will issue a request for additional information via eFiling or email.
3. Business verification / inspection. SARS may conduct a physical or virtual inspection of your business premises to confirm that you are actively trading. Industry observers note that inspections are more common for new entities, businesses operating from residential addresses, or applications with limited trading evidence.
4. Approval and VAT number issuance. If approved, SARS issues a VAT registration number.
5. Activate in eFiling. After receiving your VAT number, you must log back into eFiling, navigate to Manage Tax Types, and explicitly link the new VAT registration to your active profile. Until this step is completed, you cannot submit VAT returns.

To perform a SARS VAT registration check after submission, log into eFiling and navigate to SARS Registered Details to view the current status of your application.

VAT Registration Requirements, Documents and Acceptable Evidence

One of the most critical steps in understanding how to register for VAT in South Africa is assembling the correct documentation. Incomplete or non-compliant documents are the single most common reason for application delays. The table below sets out each required document, acceptable forms of evidence, and common rejection reasons.

Company and CIPC Documents

For companies and close corporations, SARS requires proof of CIPC VAT registration-related documentation, specifically, the company registration certificate. The standard document is the COR14.3 (for companies) or CK1/CK2 (for close corporations). Ensure the certificate reflects the current company name and registration number exactly as they appear on your SARS income tax records.

Identity and Representative Documents

A certified copy of the South African identity document or passport of the business owner, all directors, and the appointed public officer is required. Certification must be by a Commissioner of Oaths and must not be older than three months at the time of submission.

Banking and Proof of Address

SARS requires proof of the business bank account, either a stamped, original bank confirmation letter on bank letterhead or a recent three-month bank statement showing the account holder name, account number, and branch code. Additionally, you must provide proof of business address: a municipal utility account, a commercial lease agreement, or a rates and taxes statement in the business name.

Trading Evidence Examples

SARS requires proof that the business is actively generating revenue. Acceptable evidence includes:

• Invoices, copies of invoices issued to customers
• Contracts, signed service or supply agreements
• Quotations, formal quotes issued to prospective clients
• Purchase orders, orders received from customers

The SARS VAT-REG-02-G01 guide provides a comprehensive field-by-field explanation and is available as a downloadable PDF from the SARS website.

Timelines, the 21‑Day Rule and SARS Inspections

21‑Day Calculation, Worked Example

The VAT Act requires you to apply for registration within 21 days of the date on which your taxable supplies first exceeded the compulsory threshold. This deadline runs from the actual date the threshold was breached, not the end of the month or the next filing period.

Worked example: A retailer’s cumulative taxable supplies cross R2.3 million on 15 June 2026. The 21‑day clock starts on 16 June 2026, making the application deadline 6 July 2026. If the retailer fails to apply by this date, it remains liable for output VAT on all taxable supplies made from the effective date of registration, which SARS may set as early as the first day of the month in which the threshold was exceeded (1 June 2026).

Typical SARS Processing Timeline and Inspections

SARS typically processes a VAT101 application within approximately 21 business days, though this timeline can extend significantly if additional information is requested or if SARS decides to conduct a business verification. Early indications suggest that applications from newly incorporated entities, businesses operating from residential premises, or those with limited trading history face more scrutiny and longer processing times, sometimes extending to 60–90 days.

During an inspection, SARS verifies that the business is genuinely operational: premises exist, stock or equipment is present, and trading records support the turnover figures declared. Preparing a clean file of invoices, bank statements and supplier contracts before submission can reduce delays if an inspection is triggered.

If SARS Automatically Registers You, Next Steps

If SARS data, including third-party information from banks, CIPC, and other taxpayers’ submissions, suggests your revenue exceeds the compulsory threshold, SARS may register your business for VAT without you applying. If this happens, you will receive a notification and must respond promptly. Log into eFiling, go to Manage Tax Types, and link the VAT registration to your profile. You will then be required to file VAT returns from the effective date set by SARS, and any output VAT due from that date becomes payable.

Practical Decisions for SMEs, Stay Registered, Voluntary Registration and Deregistration

The increased threshold to R2.3 million from 1 April 2026 means many currently registered businesses with turnover between R1 million and R2.3 million now have a choice. Industry observers expect a significant number of SMEs to re-evaluate their VAT registration status in the months ahead.

How to Voluntarily Register (R120k Threshold)

VAT registration for small business purposes follows the same VAT101 process described above. The key difference is that you declare your taxable supplies as falling between R120,000 and R2.3 million and indicate on the form that you are applying for voluntary registration. Voluntary registration is especially beneficial for businesses with VAT-registered suppliers, as it allows recovery of input VAT on purchases.

How to Cancel or Deregister

To cancel your VAT registration, submit a VAT123 form to SARS via eFiling or at a branch by appointment. SARS will require a final VAT return, and you may need to account for output VAT on any assets (including capital assets) on hand at the date of deregistration. Professional advice is strongly recommended before deregistering, as the output tax adjustment can create an unexpected liability.

Common Issues, Errors and How to Avoid Delays

Based on practitioner experience, these are the eight most common errors that delay or derail VAT registration applications:

1. Unstamped or informal bank confirmation. Use an original bank letter on the bank’s letterhead, stamped by the branch, not a downloaded statement screenshot.
2. Name mismatches. The company name on the CIPC certificate, bank letter, and SARS records must match exactly.
3. Unsigned or expired certified ID copies. Ensure certification is recent (within three months) and signed by a Commissioner of Oaths.
4. No trading evidence. Include at least two to three invoices or a signed contract, applications with zero trading proof are routinely flagged.
5. Incorrect effective date requested. The effective date must align with when the threshold was exceeded; requesting an earlier date without justification will trigger queries.
6. Failing to activate the VAT tax type in eFiling. After approval, businesses often forget to link the VAT number under Manage Tax Types, preventing them from filing returns.
7. Late application past the 21‑day window. SARS may impose penalties and require retrospective VAT accounting on all taxable supplies from the date registration should have been effective.
8. Outdated contact details. If SARS cannot reach you via the email or mobile number on file, requests for additional information go unanswered and the application stalls.

If your application is delayed, book a follow-up appointment through the SARS eBooking system or contact your registered tax practitioner to submit a formal enquiry on your behalf.

Conclusion, VAT Registration Checklist for South African Businesses in 2026

Knowing how to register for VAT in South Africa is essential for every business approaching or exceeding the new R2.3 million compulsory threshold. The following ten-step checklist summarises the critical actions:

1. Calculate your taxable supplies over the most recent rolling twelve-month period.
2. Determine whether you have exceeded R2.3 million (compulsory) or R120,000 (voluntary).
3. If the compulsory threshold is breached, note the exact date, you have 21 days to apply.
4. Gather all required documents: CIPC registration, certified IDs, stamped bank letter, proof of address, and trading evidence.
5. Log into SARS eFiling and ensure your organisation is linked to your profile.
6. Navigate to SARS Registered Details → My Tax Products → VAT → Add new product registration.
7. Complete the VAT101 form accurately, pay particular attention to the effective date, accounting basis, and banking details.
8. Upload clearly scanned PDF documents with descriptive file names.
9. Submit the application and save the reference number.
10. After approval, activate the VAT tax type under Manage Tax Types in eFiling and begin filing returns on schedule.

Businesses currently registered with turnover between R1 million and R2.3 million should evaluate whether deregistration is beneficial, taking into account input VAT recovery, customer expectations, and the administrative cost of ongoing compliance. The likely practical effect of the threshold increase will be to free many smaller enterprises from compulsory filing obligations, but the decision to deregister requires careful analysis of each business’s specific circumstances.
