What actually happens if you register late

If you fail to register on time, SARS can backdate your registration to the date you should have registered and assess VAT on your taxable supplies from that point, whether or not you actually charged customers VAT at the time. If you didn’t add VAT to your invoices during the period you were late, you generally still owe that amount out of your own revenue once assessed.

Penalties and interest

A late payment penalty of 10% of the outstanding tax can apply, in addition to interest calculated on the outstanding amount from when it was originally due. Depending on the specific circumstances (whether the failure to register was a genuine oversight vs a more serious matter), additional understatement penalties may also apply under South Africa’s general tax administration penalty framework.

Voluntary disclosure can help. SARS’s Voluntary Disclosure Programme lets taxpayers who proactively come forward about tax irregularities, including late VAT registration, potentially receive relief from certain penalties that would otherwise apply if SARS discovered the issue itself.

What to do if you think you’re already late

Frequently asked questions

Will I definitely be penalised if I register late?

A late payment penalty and interest generally apply once identified, though the Voluntary Disclosure Programme can provide relief from certain penalties for genuine, proactively-disclosed cases.

Do I owe VAT even if I never charged my customers?

Generally yes. Your registration can be backdated, meaning you’re liable for VAT on sales made from that date, effectively absorbing it unless you separately invoice customers for the shortfall.

What is the Voluntary Disclosure Programme?

A SARS mechanism letting taxpayers proactively disclose tax irregularities, including late registration, potentially in exchange for relief from certain penalties that would otherwise apply.

Can I object to a late registration penalty?

Yes, you can lodge a formal objection through SARS’s dispute resolution process if you believe the penalty is unjustified.
