You must register for VAT in South Africa once your taxable turnover exceeds R1 million in any 12-month period. Voluntary registration is permitted once turnover exceeds R50,000 per year. Whether to register voluntarily before the R1 million threshold is a decision that depends on your client base, your expenses, and whether VAT registration helps or hurts your pricing competitiveness.
This is not tax advice. Always consult a registered tax practitioner before making VAT decisions for your business.
When is VAT registration mandatory?
You are required to register as a VAT vendor with SARS when your taxable supplies exceed R1 million in any rolling 12-month period. Taxable supplies include most goods and services you provide in the course of your business.
You must register within 21 business days of crossing this threshold. Late registration results in SARS treating you as a VAT vendor from the date you should have registered, meaning you may owe back-VAT on invoices you already issued.
SARS also allows compulsory registration if you have a written contract confirming that taxable supplies will exceed R1 million in the next 12 months, even if you have not yet reached that level.
When is VAT registration voluntary?
You may choose to register for VAT if your taxable turnover exceeds R50,000 in any 12-month period. Below R50,000, SARS will not accept a voluntary registration application.
Voluntary registration makes sense in certain situations, but it is not the right choice for every small business.
Pros and cons of voluntary VAT registration
Reasons to register voluntarily:
- Claim back input VAT on expenses. If you spend significantly on VAT-inclusive expenses (equipment, software, rent, professional services), you can claim back the VAT component. At 15%, this can be meaningful for capital-intensive businesses.
- Look more established to corporate clients. Many large companies and government entities prefer to work with VAT-registered suppliers. A VAT number on your invoice signals a level of business formality.
- Enable faster voluntary deregistration later. Once registered, you can only deregister if your turnover drops below R1 million.
Reasons not to register voluntarily:
- Your prices effectively increase by 15%. If your clients are not VAT registered (such as consumers or very small businesses), they cannot claim back the VAT you charge. Your prices become 15% more expensive overnight.
- Administrative overhead. VAT-registered businesses must submit VAT201 returns every 2 months and maintain proper records of all taxable supplies and input tax claims.
- Cash flow risk. You must pay over the VAT you collect to SARS by the 25th of the month following the tax period, whether or not your clients have paid you yet.
Quick answer
When must a South African business register for VAT?
In South Africa, VAT registration becomes mandatory when your taxable turnover exceeds R1 million in any rolling 12-month period. You must register within 21 business days of crossing this threshold. Voluntary registration is permitted once turnover exceeds R50,000 per year. Once registered, you must charge 15% VAT on all taxable supplies, submit VAT201 returns every 2 months, and pay over the collected VAT to SARS by the 25th of the following month. Voluntary registration is worth considering if your clients are VAT-registered businesses (who can claim back the VAT) or if you have significant VAT-inclusive expenses you want to reclaim. It is generally not advisable if your clients are consumers or non-VAT-registered businesses, as your prices will effectively increase by 15% from their perspective.
What changes when you register for VAT?
Once registered, you must:
- Charge 15% VAT on all taxable supplies in South Africa
- Issue tax invoices (not standard invoices) for all sales
- Submit VAT201 returns every 2 months (or monthly if SARS requires it based on your turnover)
- Pay net VAT to SARS by the 25th of the month after each tax period
- Keep records of all tax invoices issued and received for at least 5 years
- Display your VAT registration number on all tax invoices
Your invoicing software (like Rebill) needs to support VAT calculations. Rebill automatically calculates 15% VAT, shows it separately on the invoice, and includes your VAT number on all tax invoices.
How to register for VAT with SARS
- Check eligibility. Your turnover must be above R50,000 per year (or you have a written contract confirming R1 million within the next 12 months, or you have exceeded R1 million in the past 12 months).
- Register on eFiling. Go to www.sars.gov.za and log in to eFiling. Select “Register” under the VAT section.
- Complete the VAT101 form. This is the VAT registration application. You will need your business details, bank account information, and an estimate of your monthly taxable turnover.
- SARS processes the application. Registration typically takes 3 to 5 business days. SARS may request supporting documents.
- Receive your VAT registration number. This is a 10-digit number starting with 4. Add it to your invoicing software and all future invoices.
Frequently asked questions
What happens if I exceed R1 million turnover and do not register for VAT?
SARS will treat you as a VAT vendor from the date you should have registered. You will be liable for 15% VAT on all taxable supplies made since that date, even though you did not charge clients VAT. This means you effectively absorb the VAT from your own revenue. Penalties and interest also apply. Register promptly to avoid this.
Can I register for VAT as a sole proprietor?
Yes. VAT registration is available to sole proprietors, partnerships, companies (Pty Ltd), and other entities. As a sole proprietor, you register in your own name or trading name. Your VAT registration number will be linked to your ID number and tax reference number.
How often do I submit VAT returns after registering?
Most small businesses submit VAT201 returns every 2 months (bi-monthly). SARS assigns your tax period based on your turnover and the last digit of your VAT registration number. High-turnover businesses (above R30 million/year) may be required to submit monthly. You can request to change your tax period category by contacting SARS.
Can I deregister for VAT if my turnover drops?
Yes. You can apply to deregister for VAT if your taxable supplies are reasonably expected to remain below R1 million in the next 12 months. You submit a VAT123 form via eFiling. SARS will assess the application and may request supporting evidence. Deregistration does not happen automatically, even if your turnover drops below the threshold.
