What is Provisional Tax? A Simple Guide for South African Business Owners

As tax season approaches in South Africa, many small business owners and freelancers are asking: What exactly is provisional tax? And more importantly, do I need to pay it? This guide will break down the basics of provisional tax, who it applies to, and how to comply with SARS requirements without the stress.


What is Provisional Tax?

Provisional tax is not a separate tax but rather a system that allows taxpayers to pay their income tax in advance. Instead of waiting for the end of the financial year to settle a large tax bill, provisional taxpayers make payments in two (or sometimes three) installments throughout the year. These payments are based on estimated taxable income.

This system is designed to help manage your cash flow and reduce the risk of underpaying your tax liability at year-end.


Who Needs to Pay Provisional Tax?

You are required to pay provisional tax if you:

  • Earn income other than a salary (such as business income, rental income, interest, dividends, or freelance income)
  • Are a sole proprietor, partner, independent contractor, or self-employed individual
  • Run a small business or side hustle
  • Are a company or close corporation earning income not subject to PAYE

If your total taxable income exceeds R30,000 from sources other than a salary, SARS expects you to register for provisional tax.

Exceptions:

  • Individuals under age 65 with no business income and less than R30,000 in investment income per year do not need to register.

    • Optional Third Payment: September (after final return, if you underpaid)
