Provisional Tax Explained for South African SMMEs
Provisional tax can seem confusing, but it's essentially a way to pay your income tax liability in advance, ensuring you don't have a single, large tax bill at the end of the year. This guide breaks it down for small business owners.
🤔 What is Provisional Tax?
Provisional tax is not a separate tax. It is a method of paying the income tax that you owe. It requires you to submit two payments during the tax year based on your estimated taxable income. A third, optional "top-up" payment can be made after the tax year ends.
This system helps you manage your cash flow and avoid a large, unexpected tax debt when you file your annual income tax return (ITR12).
👤 Who Must Pay Provisional Tax?
You are a provisional taxpayer if you earn income other than a salary. This includes:
- Companies and Close Corporations (CCs).
- Individuals who earn business income, such as freelancers, sole proprietors, and independent contractors.
- Individuals who earn rental income or interest income above a certain threshold.
If you only earn a salary from an employer who deducts PAYE, you are generally not a provisional taxpayer.
🧮 How is Provisional Tax Calculated?
The calculation is based on an estimate of your total taxable income for the full tax year.
- Estimate Annual Income: Project your total income for the tax year.
- Deduct Business Expenses: Subtract your estimated business-related expenses to get your estimated taxable income.
- Calculate Annual Tax: Apply the relevant tax rates (for individuals or companies) to your estimated taxable income to find your estimated tax for the year.
- Subtract Tax Credits: Subtract any applicable rebates (for individuals).
- Divide for Payments:
- Your first payment is 50% of the estimated annual tax.
- Your second payment is the full estimated annual tax minus the first payment you already made.
🗓️ Key Deadlines (for February year-end)
Provisional tax is paid by submitting an IRP6 return.
- First Provisional Payment: Due by 31 August each year.
- Second Provisional Payment: Due by 28/29 February each year.
- Third (Voluntary) "top-up" Payment: Due by 30 September each year. This payment is optional and is used to settle any remaining tax liability to avoid interest charges.
✅ How to Submit and Pay
- Use SARS eFiling: The easiest way to file your IRP6 return and make payments.
- Payment: Payments can be made directly through eFiling, EFT, or at a participating bank. Always use the correct Payment Reference Number (PRN) to ensure your payment is allocated correctly.
⚠️ Penalties for Non-Compliance
SARS can impose penalties for:
- Late Payment: A percentage-based penalty on the amount paid late.
- Underestimation of Income: If your final assessed income is significantly higher than your estimate, penalties can be charged, especially on the second payment.
- Late Submission: A penalty for filing your IRP6 return after the deadline.
Pro Tip: It's often better to slightly overestimate your income to avoid underestimation penalties. If you overpay, SARS will refund you after you file your annual income tax return.
