For many South African taxpayers, the mention of “Provisional Tax” brings a sense of dread. With deadlines falling in August and February, it often feels like tax season never truly ends. However, provisional tax isn’t an additional tax; it’s simply a way to pay your income tax as you earn it, preventing a massive, unmanageable debt when your final assessment arrives.
At Leading Edge, we believe that with the right planning, provisional tax can move from a source of stress to a structured part of your financial management.
Whether you are a business owner or an individual with multiple income streams, here are our top tips for mastering your provisional tax obligations:
1. Know Your Deadlines
In South Africa, the provisional tax year runs alongside the standard tax year (March to February). There are two mandatory periods, and an optional third:
- First Period: Ends 31 August.
- Second Period: Ends 28/29 February (the most critical deadline).
- Third Period (Top-up): Ends 30 September (for individuals) or 6 or 7 months after year-end (for companies). This is used to “top up” payments to avoid interest.
Pro Tip: Mark these dates in your calendar at the start of the year. Missing a deadline results in an automatic 10% penalty.
2. Accuracy is King: The 80/90 Rule
SARS is strict about underestimation. If your final taxable income is:
- Under R1 million: Your estimate must be within 90% of your actual assessment.
- Over R1 million: Your estimate must be within 80% of your actual assessment.
Falling short of these margins can trigger heavy “underestimation penalties.” To stay safe, review your year-to-date management accounts in February before submitting your second-period return.
3. Keep Your Bookkeeping Real-Time
You cannot estimate what you haven’t measured. For businesses and freelancers, waiting until February to “do the books” is a recipe for disaster.
- The Leading Edge Approach: Use cloud accounting software (like Xero or QuickBooks) to keep your records updated monthly. This allows you to see exactly how much profit you’ve made, making your tax estimate a calculation rather than a guess.
4. Don’t Forget “Hidden” Income
Provisional tax isn’t just for business profits. As an individual, you are a provisional taxpayer if you earn more than R30,000 per year from:
- Rental income from property.
- Interest and dividends from investments.
- Remuneration from an employer not registered for PAYE.
Ensure you factor these into your August and February submissions to avoid a nasty surprise during your final ITR12 filing.
5. Factor in Your Deductions and Credits
Tax planning isn’t just about what you owe; it’s about what you can legally save. Before submitting your estimate, ensure you have accounted for:
- Retirement Annuity (RA) contributions: These can significantly lower your taxable income.
- Medical Scheme Credits: Ensure your medical aid contributions and out-of-pocket expenses are factored in.
6. Manage Your Cash Flow
The biggest challenge with provisional tax is liquidity. Paying a large lump sum in February can cripple a small business’s cash flow.
- Strategy: Calculate your expected tax liability for the year and divide it by 12. Set that amount aside in a high-interest savings account monthly. Not only will the money be ready for SARS, but you’ll also earn interest on the taxman’s money in the meantime.
